2.5 Main Circuit Recommended Wiring Table 2.5.1 below shows the recommended wiring sizes for the main circuit. Be sure to connect MCCBs

between the power supply and V31 input terminals L1(R),L2(S), L3(T). Recommended MCCBs are also listed in Table 2.5.1. When a ground fault interrupter is used, select the one that is suitable for high frequency. The current setting should be 200mA or higher and the operating time, 0.1 second or higher to prevent premature tripping.

Main Circuit Input / Output (1) Phase rotation of input terminals L1(R), L2(S), L3(T) can be in either direction. (Clockwise or counter

clockwise). (2) When inverter output terminals, T1(U), T2(V), and T3(W) are connected to motor terminals T1(U),

T2(V) and T3(W) respectively, the motor rotates clockwise as viewed from the shaft end, with a forward operation command input. To reverse the rotation, swap any two of the motor leads.

(3) Never connect AC main circuit power supply to output terminals, T1(U), T2(V), and T3(W). This can cause damage to the inverter.

(4) Care should be taken to prevent the wiring leads from contacting the V31 cabinet. If this occurs, a short

-circuit can result. (5) Never connect power factor correction capacitors or noise filters to the V31 output. (6) Never open or close contactors in the output circuit unless inverter is properly sized. (7) Do not start or stop the inverter by turning the main power switch ON or OFF. Use the control circuit

terminals or Digital Operator to start or stop the inverter.

!

Installing a Magnetic Contactor (MC) The input power supply can be connected in any phase sequence to the input terminals L1(R), L2(S), and L3(T) is not critical. If the power supply for the main circuit is to be shut off during operation, a magnetic contactor (MC) can be used. (Refer to the Fig. 2.5.1 for the main circuits wiring)

(1) The inverter can be started and stopped by opening and closing the MC on the primary side. Frequent opening and closing the MC, however, may cause the inverter to be damaged. (Limit the starting and stopping of the inverter via the MC to once every 30 minutes). (2) When the inverter is operated with the Digital Operator, automatic operation cannot be performed after recovery from a power interruption. (3) To decrease electrical noise interference, add a R-C surge suppressor (snubber) (R:10Ω/W,

C:0.1uf/1000Vdc), at the two terminals of coils of the magnetic contactor.

230V class: 7.5 to 30HP, 200 to 240Vac 50/60Hz, 3 phase

460V class: 7.5 to 40HP, 380 to 480Vac 50/60Hz, 3 phase

Installing AC Fuses Fuses are principally used to isolate a catastrophic failure within the inverter (e.g. IGBT shorted) or more likely, a short circuit between the mains-to-inverter cables. For the entire v31 models have a standard built-in DC fuse to isolate the short-circuit inside the inverter. Separate AC fuses provided by the end user are required to protect models without built-in fuses. Refer to Chapter 12.5 for the recommended AC fuses. Fuses from other manufactures’ can be used provided they meet the requirements covered in Chapter 12.5.

WARNING!. Do not remove the AC fuses when the inverter is running.. Check to ensure that there are no obvious short circuits or overloads in the protected circuit when the fuse is blown. Extensive damage can be caused to both electronic equipment and associated electrical equipment by replacing fuses or resetting circuit breakers without correcting the problem.


2-9

!

Installing a Molded-Case Circuit Breaker (MCCB) Always connect the power input terminals L1(R), L2(S) and L3(T) to the power supply using a molded-case circuit breaker with a capacity of 1.5 to 2 times the Inverter’s rated current. For the MCCB’s time characteristics, be sure to consider the inverter’s overload protection (150%, 1 minute). If the same MCCB is to be used for more than one inverter, or other devices, set up a sequence so that the power supply will be turned off by a fault output, as shown in Fig 2.5.1. Installing a Ground Fault Interrupter(GFI) On the inverter primary side, when a ground fault interrupter (or ELCB: Earth Leakage Circuit Breaker) is used, select one with a fault current detection of 200mA or more per inverter, and with an operating time of 0.1sec or more. For a special-purpose ground fault interrupter, select one with a fault current detection of 30mA per inverter. In this case, the RFI jumper connector for the IT mains shown in Fig. 2.5.2 must be placed to the OFF position to reduce the earth leakage currents. (Note that the EMC performance will be reduced, when the RFI connector is opened)

Fig. 2.5.2 Earth Leakage Current RFI Jumper for IT Mains By placing the RFI Jumper to the OFF position removes the Y capacitor on IT main supplies. (Refer to fig 2.5.3 for the RFI jumper connection location)

Fig. 2.5.3 RFI Connections Driving a 440V Motor If the wiring length between inverter and motor is excessively long, the insulation of the motor that is driven with a PWM (Pulse Width Modulation) type inverter, may be deteriorate do to the high dv/dt voltage generated by PWM. This is especially true for 440V class motors, so any of the following measures should be taken when operating a 440V class motor.

(1) Use a motor with reinforced insulation (the TECO’s inverter duty motors have reinforced insulation). (2) The wiring between the motor and inverter should be as short as possible (less than 10m). (3) Connect an optional sinusoidial filter to the inverter output terminals (Refer to Chapter 12.4).

Grounding ( PE: Protective Earth )

(1) The inverter grounding terminals PE ( ), must be grounded to ensure your safety and to minimize Electrical noise. Table 2.5.2 is the technical standard for the grounding of electric equipment having metal frames to prevent electric shock and fire.

Table 2.5.2 Grounding Resistance

Voltage class Grounding work class Grounding resistance

230V Type D 100Ω or less

460V Type C 10Ω or less

(2) Never connect the ground of the V31 in common with welding machines, motors, and other large-current electrical equipment. Run the ground lead for the V31 in separate conduit from leads for large-current electrical equipment. (3) Use the ground leads which comply with AWG standards and make sure the length is as short as possible. (4) Where several V31 units are used side by side, it is preferable to ground each unit separately, Fig. 2.5.4 (a). However, connecting all the ground terminals of V31 in parallel while grounding only one of the V31 to the ground pole is also permissible, Fig.2.5.4 (b). Do not to form a loop with the ground leads, Fig. 2.5.4 (c).

Braking Resistor Connecting Terminals There is a braking transistor built-in as standard for 230V/460V, 20HP (and below). A braking transistor can be optionally built in for 460V, 25HP (and above) (select the models: JNV31-4 口口口口-B3 口口). A braking resistor (unit) can be connected to the braking resistor terminals B1 and B2 directly for those models. Refer to Fig 2.5.5. Keep the wiring length of braking resistor to less than 5m, and the two leads should be twisted.

Fig. 2.5.5 Braking Resistor Connecting Diagram

(1) When a braking transistor is required for 230V, 25HP (and above) or 460V, 25 to 40HP without a braking transistor built-in (Models: JNV31- 2 口口口口-H3 口口口 , JNV31- 4 口口口口-H3 口口口), a braking unit should be used.

Notes -

1. Digital input signals S1 to S8 can operate in the Sink (NPN) mode where (SC = 0V) is common or Source (PNP) mode where (SC = +24V Factory default) is common and is selected by jumper JP4. An external 24V power supply can also be used. (Refer to table 2.8.1)

2. The output current capacity of the 24V terminal is 250mA max. This is inclusive of all boards, the VCC power supply and when used as external power back-up for the control unit.

4. The output current capacity of the +12V and -12V power supply is 20mA max.. 5. Dip switch SW1-2 sets analog input terminal AI2 for voltage (V position) or current (I position factorydefault). 6. Dip switch SW1-3 sets analog input terminal AI3 for a voltage (V position factory default) or current (I

position) 7. The internal resistance of the analog inputs AI1, AI2 and AI3 is 2MΩ for voltage signals, and 250Ω for

current signal. 8. Dip switch SW1-1 in the ON position internally connects a 110Ω terminating resistor to the RS-422

/RS-485 communication input terminals R(+), R(-). The resistor is disconnected in the OFF position which

is the factory default. 9. The PG (Encoder) interface is built-in as standard, and no external PG feedback option card is required.

The PG interface is designed for open-collector inputs. Shield twisted-pair cable less than 100 meters in length should be used between the inverter and the PG. The PG circuit wiring (terminals A, B, VCC, VSS) is not required for operation without a PG. The direction of rotation of the PG can be set by parameter G31-10 (PG Rotation Direction), and the factory preset phase-A leads phase-B by 90° when the motor operates in the forward direction (CCW). PG phase-A and phase-B pulses can be monitored by using the pulse output terminals PO1 and PO2 (Set G14-6 to 9). For a single A/B line driver encoder feedback interface, please select optional terminal card TER-002. (Refer to Chapter 10.4)

10. Depending on the PG input voltage rating, place the shorting jumper of JP3 to the +5V (factory default) or +12 position to supply power to the PG. The internal +5V/+12V power supply capacity is 200mA. If the

PG power requirements are greater than 200mA, a separate power supply is required. (Refer to Chapter 10.5).

11.Pulse input specifications are given in Table 2.9.1.

(b) “Stationary” will be displayed during stationary auto-tuning (T-01=1), and the motor does not rotate. (c) The RUN LED (on the upper left of RUN key) will be lit during auto-tuning. (d) An “>>>” signal corresponding to the auto-tuning processing time will be displayed during

auto-tuning. 4- The auto-tuning operation is aborted when the STOP key is pressed during auto-tuning. Press the RESET key to return to the Mode Display screen. Always use the STOP key on the Digital Operator to

abort the auto-tuning process.


5-14

5- When a fault has occurred during auto-tuning, a fault message and an uncompleted message are displayed on the Digital Operator. The RUN LED will be blinking, and the motor will coast to stop.

(Refer to Chapter 9.4 for the Auto-tuning Faults.) Fault displays can be cleared by pressing the RESET key, and the Mode Display will appear. — All set parameters (group 06 through group 07 parameters) will revert to their factory settings if a

fault occurs. The related parameters must be entered again before re-starting auto-tuning. — The “>>>” signal will remain for the time that the fault exists during auto-tuning.

6- If auto-tuning has been completed successfully, the RUN LED will turn off. Press the BACK key to return to the Mode Display, and proceed to the next operation. The entire auto-tuning operation takes up to approx. 50 seconds.

6.3 Control Method Selection 6.3.1 Introduction to Various Control Methods

The speed control methods are roughly divided into open loop and closed loop types. The intent is to select the best control mode (algorithm) for the motor characteristics in your application. Each control method generates the voltage / frequency output in a unique way, and once configured, it is the basis for other parameter settings as well. Therefore, choose the suitable control method via parameter G01-03, or G34-01 for motor 2, early in your application design process.

Fig. 6.3 Speed Control System

Referring to figure Fig. 6.3 above for the speed control system: . The open loop V/F control system does not need any speed sensor and is primarily used for a general purpose inverter applications. It is suitable for the simple speed control of existing motors and for

variable torque loads such as fans and pumps. . The slip compensation control is provided to maintain the set motor speed with torque load changes.

By sensing the motor terminal voltage and primary current changes resulting from torque load variations, the inverter output frequency is adjusted to maintain the setting speed.

. The closed loop control system compensates for speed variations according to speed feedback

information. The speed feedback information (Nfb) is obtained from a speed sensor (transducer) such as an encoder (PG) and is compared with the speed reference (Nref). The difference between (Nref) and (Nfb) results in an error signal that is used to control the inverter output frequency so that the speed sensor value will try to equal the speed reference value. The V/F + PG, SLV (Sensorless Vector) and SV (Sensor or Flux Vector) control modes are used for closed-loop speed control.


6-5

6.3.2 Closed Loop Control System (a) V/f + PG Control:

In this type of control, the inverter compensates for speed changes due to load variations, by measuring the difference between the Ref. and the feedback (PG) values and outputting a slip frequency. This type of control is relatively simple and is largely used for the speed control of general purpose inverters. However, since it is based on the V/f control it is not suitable for applications requiring quick response times.

(b) Sensorless Vector Control: Flux vector control results in quick response and high accuracy but requires a speed sensor for feedback. On the other hand, Sensorless vector control does not require a speed sensor but it is slightly lower in performance than flux vector with feedback. This method calculates the actual motor speed from the motor terminal voltage and primary output current and adjusts the output frequency (motor speed) using the calculated speed as a feedback signal.

Note - Sensorless vector operation must be disabled when two or more motors are connected (parallel operation) to the inverter.

(c) Flux Vector (Sensor) Control: The Sensor vector control mode results in rapid motor response to torque load changes. This mode controls the primary output current to the AC motor which consists of two components; magnetic flux current (Id) and torque current (Iq). This results in a control performance equivalent to that of DC motor controllers. (Refer Fig. 6.5 below). The motor parameters, (group G07), are used by the vector processor and therefore, the performance greatly depends on the accuracy of the parameters.

6.4 Auto-tuning When using the SLV (Sensorless Vector) or SV (Sensor Vector) control method, or when the motor cable length is long for the V/F (or V/F + PG) control method, perform auto-tuning to calculate the required motor parameters to optimized system performance.

6.4.1 Setting the Auto-tuning

There are two auto-tuning modes that can be set; rotational auto-tuning and stationary auto-tuning: (1) Rotational Auto-tuning (T-01=0)

Set T-01=0, input the related motor data listed on the motor nameplate, and then press the RUN key on the Digital Operator. The motor will rotate for approximately 50 seconds and then store the required motor parameters automatically. (Refer to Chapter 5.3.5 for the auto-tuning operations.)

(2) Stationary Auto-tuning (T-01=1) Set T-01=1, input the related motor data listed on the motor nameplate, and then press the RUN key on the Digital Operator. The Inverter will supply power to the motor but the motor will not rotate. After approximately 50 seconds selected motor parameters will be calculated and set automatically. The remaining motor parameters can be set by calculation if necessary (normally, adjustment is not required). (Refer to Chapter 8.1.07 for the motor parameters setting and Chapter 5.3.5 for the auto-tuning operations.)

6.4.2 Precautions for Auto-tuning

. Use stationary auto-tuning (T-01=1) whenever performing auto-tuning for a motor that is connected to a load, otherwise, incorrect motor parameters may be recorded, and the motor may not operate properly. . Use rotational auto-tuning (T-01=0) whenever performing auto-tuning for a motor that is not connected to a load to obtain better performance. The motor shaft will rotate when rotational auto-tuning is being performed therefore, confirm safety and ensure the a holding brake if one is used is not applied. . The Multi-function Digital Inputs will not effect during auto-tuning (either stationary or rotational), and the Multi-function Digital Outputs will maintain the same status as normal operation. Always use the STOP key on the Digital Operator to abort auto-tuning. . Power will be supplied to the motor during stationary auto-tuning even though the motor does not rotate. Do not touch the motor until auto-tuning has been completed. . If the maximum output frequency (G06-03, Fmax) and base frequency (G06-04, Fbase) are different, set the maximum output frequency (G06-03) after auto-tuning.

. To improve speed response and stability in V/f control with a PG (G03-01=1), set the ASR parameters (G30-01 to G30-05) to between 0.5 and 1.5 times the default. (It is not normally necessary to adjust this setting.) ASR for V/f control with a PG will only control the output frequency; a high gain, such as is possible for SLV mode or SV mode, cannot be set.

2-Wire Mode Operation . Inverter operations using a 2-wire control is implemented by setting G10-01 (Terminal S1 function Selection) to 0 (Forward RUN/STOP, factory setting) and G10-02 (Terminal S2 Function Selection) to 1 (Reverse RUN/STOP, factory setting).

. When control circuit terminal S1is ON and S2 is OFF, the inverter will operate in the forward mode, and when S1 is OFF, the inverter will stop.

. When control circuit terminal S1 is OFF and S2 is ON, the inverter will operate in reverse mode, and when S2 is OFF and S2 is ON, the inverter will stop. . 2-wire control is as shown in Fig.8.1.4 below. S1 and S2 cannot be ON at the same time for more than 500ms or the warning message “EF9 (blinking) FWD-REV Error” will be displayed and the inverter will stop. After the condition is cleared the inverter will return normal.

Fig. 8.1.4 2- wire Mode Connection Example . When the inverter is initialized for 2-wire control by setting G01-04 (Initialize) to 2,4 or 6 (2-wire Sequence initialization), Multi-function Input Terminal S1 becomes the Forward RUN/STOP command, and S2 becomes the Reverse RUN/STOP command.

3-Wire Mode Operation . When any parameter from G10-03 to G10-08 (Multi-function Digital Input Terminal S3 to S8) is set to 4, terminals S1 and S2 will be set for 3-wire control using a RUN command and a STOP command individually. and their original function is disabled, and the multi-function digital input terminal that has been set function as a Forward/Reverse command terminal. . When the inverter is initialized for 3-wire control by setting G01-04 (Initialize) to 3, 5 or 7 (3-wire Sequence initialization), Multi-function Digital Input Terminal S5 becomes the Forward/Reverse command input terminal. . Fig. 8.1.5 below is an example of 3-wire control. Multi-function input terminal S5 is used as the forward

8.1.4 Group 04 – Carrier Frequency Selection

Carrier Frequency (G04-01)



V/F +

PG SLV SV

G04-01 Carrier Freq. 0 to 16 Carrier Freq. Varies by KVA A A A A

1 When G04-01= 2 to 16, the carrier frequency in KHz units is a fixed pattern for the PWM output. 2 When G04-01= 0, it enables detailed settings using G04-05 to G04-07.

When SLV and SV mode, the min. value of G04-01 is 4. The setting range depends on the inverter capacity (G45-01) and CT/VT mode (G02-08).

When the PWM carrier is low, the motor acoustic noise increases, but the RFI and EMI interference noise generated and the leakage current decrease. Refer Table 8.1.3 below showing the effects of carrier frequency. Table 8.1.3 Effects of Carrier Frequency

Carrier frequency (G04-01=2 to 16)) 2KHz--6K--10K--16KHz Motor Acoustic Noise High -------------- Low

Output Current Waveform Bad ---Good---- Bad Interference Noise Low --------------- High Leakage Current Low --------------- High

. The setting range and factory setting depends on the inverter capacity. Refer to Section 4.1 Basic

Specification for the factory setting and maximum limit selectable for this parameter. . Increasing the carrier frequency reduces the capacity of the inverter unit. Refer to chapter 11, for the de-rating curve.

. Reducing the setting increases the motor loss and raises the motor temperature. Increasing the setting increases inverter loss and raises the inverter temperature.

. Low carrier frequency produces less noise but greater current ripple, while high carrier frequency produces greater noise but less current ripple. Output current waveform performance is good at 6~10KHz. If higher carrier frequency is needed, avoid No-load operation at inverter output frequency above 20Hz. The high carrier frequency current waveform is good when load is applied.

. If the cable between the inverter and the motor is excessively long, the high-frequency leakage current will increase causing the inverter output current to increase as well and may affect peripheral devices. To prevent this, adjust the carrier frequency as shown in Table 8.1.4.

Table 8.1.4 Cable length and Carrier Frequency

Cable Length < 30m 30m - 50m 50m -100m > 100m Carrier Frequency (G04-01 Setting)

14KHz max (G04-01=14KHz)




. Reduce the carrier frequency if the speed and torque are inconsistent. . When using V/F and V/F+PG control mode, you can vary the carrier frequency according to the output Frequency by setting G04-05(Carrier Frequency Max. Limit), G04-06(Carrier Frequency Min. Limit) and G04-07(Carrier Frequency Proportional Gain).

Setting G04-02 to 1 enables Soft-PWM control, which changes the motor acoustic noise quality. Soft-PWM control can alter the motor generated metallic acoustical sound, which may be more pleasant to the human ear. It also limits RFI noise to minimum levels. The factory setting is Soft-PWM control OFF (Disabled). When the Soft PWM function is enabled, the maximum carrier frequency will be limited to 8kHz.

Auto carrier frequency change function is disabled, the operation carrier frequency depends on the G04-01 setting.

(2). G04-03=1 Auto carrier frequency change function is enabled, the inverter will reduce the carrier frequency automatically when the heat sink temperature is too hot. (Refer to Chapter 11 for the de-rating guidelines)

The carrier frequency characteristics differ according to the control method. 1 V/F and V/F+PG control mode: Fixed carrier frequency pattern when (G04-01=2 to 16) and variable carrier frequency with output frequency when (G04-01=0) are possible. 2 SLV and SV control mode: Fixed carrier frequency pattern only (G04-01=2 to16).

. In the V/F and V/F+PG control mode, the carrier frequency can be change in response to the output frequency by setting G04-05 to G04-07 as per the following figure.

. Use the carrier frequency variable with output frequency setting as above to reduce the carrier frequency if speed and torque are inconsistent in the V/F and V/F+PG control mode. . To fix the carrier frequency, either set the same value in G04-05 and G04-06 or set G04-07 to 0. . If the carrier frequency proportional gain (G04-07) > 6 and G04-05 < G04-06, a “SE01 Set Range Error” warning message will occur. . If the minimum limit (G04-06) is set higher than the maximum limit (G04-05), the minimum limit will be disregarded and carrier frequency will be fixed at the maximum limit (G04-05).

. In the SLV and SV control mode, the maximum limit of the carrier frequency is fixed in G04-05. NOTES-

V/f Pattern Setting (G06-03 to G06-12) . G03-03 to G06-11 can only be set by the user when G06-02 has been set to “F” or “FF”. If G06-02 is

set to anything other than F or FF, the parameters cannot be changed. . Please follow the hierarchy for frequency setting, otherwise an warning message “SE03, V/f Curve Error” will display.

Fmax ≥ Fbase ≥ Fmid1 ≥ Fmid2 ≥ Fmin G06-03) (G06-04) (G06-05) (G06-06) (G06-07)

. There is no hierarchy for the voltage setting ( G06-08 to G06-11 ).

. If the V/f characteristics are linear, set G06-06 (Fmid2) and G06-07 (Fmin) to the same value. In this case, G06-10 will be ignored.

. When changing control method via G01-03, parameters G06-07 (Fmin) and G06-11 (Vmin) will change the factory settings for that control method.

. Refer to following figure for user-defined V/f pattern.

Fig. 8.1.20 User Defined V/f Pattern

. Set the V/F curve based on the motor allowable load characteristics. In high torque-low speed application, it is likely that the motor will overheat. If the motor runs a prolonged time under these conditions, special attention must be paid to cooling the motor.

. If the auto-torque boost function is activated via G29-01, the voltage to the motor changes automatically to provide sufficient motor torque to start and run at low frequencies.

V/f Pattern Setting for SLV/SV Control . Normally it is not necessary to adjust the V/f pattern for SLV control mode. Adjust the V/f pattern when you want to change the maximum output frequency setting (G06-03, Fmax), base frequency (G06-04, Fbase), minimum output frequency (G06-07, Fmin).

. Since SV/SLV mode use a current controller, G06 group can only control the frequency pattern of SV/SLV mode. Voltage output is controled automatically. If motor need to be operated at constant horse power region or high speed area above motor rated frequency, Preweaken the flux by decreasing motor no-load voltage G07-05 or T-05 10~40V lower than inverter input voltage and re-autotuning again. When no-load voltage is decreased, inverter won’t saturate and gain more voltage for torque control, hence hunting can be prevented. The only drawback is that preweakening flux increases current.

. The base frequency (G06-04, Fbase) needs to be set as rated frequency in motor nameplate of for SLV control.

. The best setting of base frequency (G06-04, Fbase) for all control mode is the rated frequency in motor nameplate

Manual Torque Boost When the motor is connected to a high inertial load or the starting friction (break-away) is high, the starting torque may need to be increased by boosting the voltage above the normal V/f ratio as shown below in Fig. 8.1.21. However, running the motor at a low speed for a long periods of time can cause the motor to overheat. A motor with a built-in fan for cooling may be necessary.

. The motor parameter settings are as follows. Since these motor parameters are set automatically when motor 1 is selected (T-09=1) during auto-tuning, readjustment is not normally required except for some special applications such as the constant horsepower control for machine tool spindle motor etc. Cont.

(1) Number of Motor poles Setting (G07-01). . Sets the number of motor poles as written on the motor nameplate.

(2) Motor Rated Slip Setting (G07-02). . At V/F mode, set G07-02 to the motor rated slip calculated from the rated speed on the motor nameplate. The amount of rated slip frequency =

12001)-poles(G07 Motor*07)-speed(T rated Motor-06)-Tfrequency( rated Motor

. Normally it doesn’t need to set G07-02 at SLV/SV mode. G07-02 can be acquired from autotuned rotor

resistance, mutual inductance, leakage inductance and excitation current at SLV/SV mode. (3) Motor Rated Output Power (G07-03). Sets the value on the motor nameplate. (4) Motor Rated Current (G07-04). Sets the motor nameplate full load current. The parameter is the same as T-03. If this parameter is modified at SLV or SV mode, a rotational autotuning is suggested. (5) Motor NO-Load Voltage (G07-05).

. This parameter is the same as T-10. When T-10 or G07-05 is set, G07-05 or T-10 is also set as well. It defines the motor rated flux at rated speed. Set this value 10~50V lower than the inverter input voltage to ensure torque performance at rated frequency or higher frequency.

. Smaller No-Load voltage will reduce No-Load current, weaken the flux and increase loading current.

. Larger No-Load voltage will increase No-Load current, enhence the flux and reduce current when load is

applied. The enhenced flux also cause larger back electromotive force which saturates inverter output and makes torque control failed.

If this parameter is modified at SLV or SV mode, a rotational autotuning is suggested. (6) Motor Excitation Current Reference (G07-06).

. This parameter is set automatically at autotuning, adjustment in not normally required.

. If it is required to set G07-06, set G07-06 as percentage of motor rated current(G07-04).

. The slip compensation is activated when the output current is greater than motor no-load current in V/f control mode.

(7) Motor Core Saturation Coefficient 1,2 and 3 Settings (G07-07, G07-08, G07-09). . These parameters are set automatically at autotuning, adjustment normally is not required. . These parameters set the motor core saturation coefficient at 50% (G07-07), 75% (G07-08) and

137.5%(G07-09) of rated flux separately to compensate core saturation effect. . Core saturation coefficient is defined as the percentage of motor excitation current(G07-06). When flux is at

137.5% level, the core saturation coefficient should be larger than 137.5%. When flux is at 50% or 75%, the core saturation coefficient should be less than 50% or 75%, respectively.

(8) Motor Core Loss Setting (G07-10). . Sets the motor core loss as a percentage of motor rated output for torque compensation.

voltage (T-04). . The slip compensation is activated when the output current is greater than motor no-load current in the V/f

control mode. . G07-04 must be greater than G07-15, otherwise a warning message “SE01 Set Range Error” may occur. . Refer to the following Fig.8.1.22 for the inductor motor Y-Equivalent model for the motor parameters.

( 1 ) Motor Overload protection Selection (G08-01).

. Sets the motor overload protection function in G08-01 according to the applicable motor. ‧ Disables the motor overload protection function (set G08-01=---0B) when two or more motors are connected to a single inverter. Use an alternative method to provide separate overload protection for each motor such as connecting a thermal overload relay to the power line of each motor. ‧ The motor overload protection function G08-01 should be set to --1-B (hot start protection characteristic curve) when the power supply is turned on and off frequently, because the thermal values are reset each time when the power is turned off. ‧ For motors without a forced cooling fan (general purpose standard motor), the heat dissipation capability is lower when in low speed operation. Set G08-01= -0--B. ‧ For motors with a forced cooling fan (inverter duty or V/F motor), the heat dissipation capability is

not dependent upon the rotating speed. Set G08-01 = -1--B. . To protect the motor from overload by using electronic overload protection, be sure to set parameter G07-04 according to the rated current value shown on the motor nameplate.

. Refer to the following Fig 8.1.23 for the standard motor overload protection curve example (G08-01= -0--B)

( 2 ) Motor Overheat Protection Selection (G08-02 to G08-05) . Perform motor overheat protection by using the thermistor temperature resistance characteristics of the PTC (Positive Temperature Coefficient) sensor built into the windings of the motor. . The PTC thermistor is connected to terminals MT and GND. If the motor overheats, the OH3 (motor pre-overheat) and OH4 (motor overheat) error codes will be displayed.

(1).When G08-02=0 or 1 (stop operation when pre-overheat occurred), and the PTC thermistor input exceeds the pre-overheat alarm detection level, the Digital Operator will display “OH3 Motor Pre-Overheat” fault message, and the fault contact output will operate. (2).When G08-02=2 (continue operation when pre-overheat occurs), and PTC thermistor input exceeds the pre-overheat alarm detection level, the Digital Operator will display “OH3 Motor pre-overheat (blinking)” alarm message and the fault contact output does not operate. (3).The motor overheat protection is active when the PTC thermistor resistance RT=1330Ω and the delay time set by (G08-04) has expired. The Digital Operator will display “OH4 Motor overheat” fault message, and the fault contact output operates. The motor will stop in accordance with the stopping method set in G08-03.

The stall prevention during the acceleration function is used to prevent excessive current due to high motor loads or a rapid acceleration requirements. . When the stall prevention function during acceleration is set (G09-01=1), and the inverter output current exceeds the (G09-02) -15% level, the acceleration rate will begin to decrease. When the value of G09-02 is exceeded, the motor stops accelerating. . If the motor capacity is smaller than the inverter capacity, decrease the set value of G09-02 if the motor stalls.

. The inverter rated output current should be set to the 100% level. . Refer to Fig. 8.1.25 below showing stall prevention during acceleration.

Fig. 8.1.25 Stall Prevention During Acceleration . If using the motor in the constant horse power (CH) region, the stall prevention level (G09-02) will be automatically lowered to prevent stalling. The stall prevention level during acceleration in the constant horsepower region is reduced as follows. Accel stall prevention level (in CH region) =【Accel stall prevention level (G09-02)】×【Fbase (G06-04)】

Output frequency . G09-03 is the limit value to prevent the stall prevention level in CH region from being reduced more than necessary. Refer to the following Fig. 8.1.26.

Accel/Decel Time Selection1 (Setting=12). (14). Accel/Decel Time Selection2 (Setting=13). Refer to chapter 8.1.3 “Accel/Decel Time Switching by Multi-function Digital Input Terminals”. (15). Emergency stop (Setting=14). Refer to Section 8.1.3 “Emergency stop Deceleration Time”. (16). External Baseblock command (Setting=16). . Refer to Section 8.1.3 “Emergency stop Deceleration Time”. . Either of these settings will perform a baseblock command using the Multi-function Digital Input terminal ON

/ OFF operation, and prohibit inverter output. . During running : When an external baseblock signal is detected, the Digital Operator will display ″EFn Ext Fault (Sn)″, where n=1- 8. and the inverter output is blocked. After the baseblock signal is cleared, the motor will resume running according to the reference signal. To restart the operation, use speed search from frequency reference prior to the previous baseblock command input. . During deceleration : When an external base block signal is input, the digital operator will display ″EFn Ext. Fault (Sn)″, where n=1- 8 and the inverter output is blocked. The motor will then coast to stop. After this external baseblock signal is cleared, the inverter will stay in the stop mode. . During acceleration : Operation same as during running. Refer to the following Fig. 8.1.33 for the time chart when using the baseblock command.


8-45

Fig. 8.1.33 External Baseblock Operation (17). Inhibit ACC / DEC Command (Setting=18). . The Inhibit ACC / DEC command ( Input from the Multi-function Digital Input terminals ) will pause the acceleration/deceleration of motor and maintain the output frequency. The output frequency will be recorded at that time if G45-02=1 (The output frequency in the hold state will be recorded ). Acceleration/Deceleration will restart when the Inhibit ACC / DEC command is removed. . If G45-02 (Frequency reference recording function) is set to 1 (frequency reference on hold is recorded), and the Inhibit ACC / DEC command is input, the output frequency is stored even after the

power supply is turned OFF. . Refer Fig. 8.1.34 below for the Acceleration / Deceleration inhibit operation.

Fig. 8.1.34 Acceleration / Deceleration Inhibit Operation

*1. When G45-02=1, and the Inhibit ACC / DEC command is input, the output frequency on hold is stored even after the power supply is turned off. When a RUN command (e.g. Forward Run) is input, and the Inhibit ACC / DEC command is turned ON, the output frequency will accelerate to the previous stored on hold output frequency.

*2. When G45-02=0, and a run command is input with the Inhibit ACC / DEC command is turned ON, the output frequency will be set to zero.


8-46

(18). Inverter Overheat Warning (Setting=19). When the inverter detects an overheat signal, the LCD Digital Operator will change its display to “ INV OH Warning ”, and the inverter will still maintain its operation. When the inverter overheat warning signal is off, the Digital Operator will restore its previous display automatically and the RESET key does not need to be pressed. (19). FJOG Command (Setting=20). (20). RJOG Command (Setting=21).

. Jogging can be performed in forward or reverse direction. Setting = 20 : FJOG command ( ON : Run forward at the jog frequency set by G05-17 ) = 21 : RJOG command ( ON : Run reverse at the jog frequency set by G05-17 ) . The FJOG and RJOG commands have priority over other frequency commands. . The inverter will stop running via the stopping method set by G02-03 ( Stopping Method Selection ) when the FJOG and RJOG commands are both ON for more than 500ms. (21). UP Command (Setting=22). (22). DOWN Command (Setting=23). . The inverter can use either the Digital Operator (Refer to G45-06) or an external Multi-function Digital Input (terminal S1 to S8) to change the output frequency upward or downward while the motor is running. . When using the external Multi-function Digital Input terminals to perform the UP/DOWN operation, set G02-02 (Run Command Selection) to 1 (Control terminal) , then set one of the parameters G10-01 to G10-08 (Multi-function Digital Input terminals S1 to S8) to 22 (UP command) and 23 (DOWN command). Two terminals need to be used so that the UP and DOWN commands can be used as a pair. . The Output frequency will follow the set acceleration and deceleration times. . An operation error “SE02 DI terminal Error” will be displayed when:

(1). Only the UP or Down command has been set. (2). The UP/DOWN command and Inhibit ACC/DEC command are both on at the same time. (3). The UP/DOWN commands were selected while PID is enabled (G23-01).

. Refer to Fig. 8.1.35 below for an example of the connections and time chart for the UP/DOWN operation.

Fig. 8.1.35 UP/DOWN Connection Example


8-47

Fig. 8.1.36 Up / Down Commands Time Chart . When the UP / Down command is being used, the output frequency will accelerate to the Frequency

Reference Lower Bound (G05-19) if a RUN command is input. . The output frequency is limited by the Frequency Reference Upper Bound (G05-18) and Lower Bound (G05-19) when the UP / DOWN command is being used. . When G45-02 (Frequency reference recording function) is set to 1 ( Frequency reference on hold is recorded ), the frequency reference on hold using the UP / DOWN command is stored even after the power supply is turned off. When the power supply is turned on again, and the run command is input, the output frequency will accelerate to the previous stored frequency reference.

. The acceleration / deceleration time used with this function is the same as for normal operation, Tacc1 /Tdec2 (G03-01,02) or Tacc2 / Tdec 2 (G03-03, -04).

*1. When G45-02=1, and the run command is input, the output frequency will accelerate to the previous stored frequency reference. *2. When G45-02=0, and the run command is input, the output frequency will accelerate to frequency reference lower bound (G05-19). (23). Synchronization Command (Setting=24). . This function switches between the frequency reference converted from a pulse train input and other frequency reference (according to G02-01 setting). . This function is ineffective if any digital input is as the Local/Remote control selection (setting =5) or remote mode operation selection (setting = 6) and the corresponding digital input is on. . This function is ineffective if local mode is set by keypad local/remote key.

. The inverter must be in the STOP mode in order to set/clear Synchronization command. . Refer to Fig. 8.1.67 and Fig. 8.1.68 for synchronization operation. (24). DC Injection Braking Command (Setting=25). . With this setting, you can apply the DC injection brake to the motor by turning on the terminal for which the DC injection brake command has been set when the inverter is being stopped. . If a Run command or Jog command is input, the DC injection braking operation will be cleared and the motor will begin to run. Refer the following Fig. 8.1.37 for the DC injection braking time chart.

It is mainly used for special applications such as to control a smoke fan etc. (40). RTC Timer Enabled (Setting = 43). . To enable the RTC timer function (when G42-04=2) . Refer to parameter group 42. “RTC Timer Function”. (41). RTC Offset Time Enabled (Setting = 44). . To enable the RTC offset time (when G42-21=2) . Refer to parameter group 42. “RTC Timer Function”. (42). KEB Acceleration (Setting = 45). . To enable the KEB acceleration (when G41-01 is not 0) . Refer to parameter group 41. “KEB Function”. (43). Parameter Write Enabled (Setting=48). Refer to G01-02. If you set one of the G10-01 to G10-08 to 48 (Parameter write enable), you can store parameters from the Digital Operator when the control terminal is on. When the control terminal is off, all parameters except the frequency reference (G02-01) are write protected. (44). Manual Energy-saving command (Setting=49). . ON: Manual energy saving control set for G24-11, G24-12. Refer to Fig. 8.1.91 for the Manual Energy Saving Operation. (45). Unattended Start Protection (Setting=50). . If the RUN command is already preset (Controlled by terminals) and when power is turned on, the inverter starts running immediately after power-up. The unattended start protection (USP) function (When one of G10-01 to G10-08 is set to 50) prevents an automatic startup, so that the Inverter will not run without outside intervention. Refer the following Fig. 8.1.40 for USP operation.

Fig. 8.1.40 USP Operation

. The Fault (Alarm) signal indicates that a USP Trip warning and a corresponding fault or alarm signal. When the fault or alarm is active, there are two ways to reset the fault signal and resume running : Turn the RUN command OFF, or perform a reset operation by terminal input or the RESET key on the Digital Operator.

. If a dc voltage is applied to an operating motor, the motor generates a braking torque. This is referred as dc injection braking and parameters G16-01 to G16-04 specify the settings. . The DC Injection braking should be disabled if the speed search function is enabled. . The DC injection braking function is initiated by applying a DC current to the motor. This happens in the DC Injection braking time at start (G16-04) and DC Injection Braking Time at stop (G16-03). . For the DC injection braking time at start (G16-04), set the DC injection braking operating time when the motor is to start. This will prevent the load from back driving the motor (“Windmill effect”), and allow a normal acceleration from a stop. . If G16-04 is set to 0 (Disable the DC injection brake at start), the inverter starts from the minimum output frequency set by (G06-07). . For the DC injection braking time at stop (G16-03), set the DC injection braking operating time for when the motor is to be stopped. If G16-03 is set to 0 (Disable the DC injection brake at stop) the inverter output will be blocked when the output frequency is less than the DC injection braking starting frequency (G16-01). If the set level of DC injection braking starting frequency (G16-01) is lower than the minimum output frequency (G06-07), the DC injection braking will begin from the minimum output frequency. . The DC injection braking current level is set by parameter (G16-02) for start or stop. The DC injection braking current (G16-02) is set as a percentage of the inverter rated output current (The inverter rated output current is set as 100%). The DC injection braking current parameter (G16-02) is not used with Sensor Vector (SV) control and can not be set. . Lengthening the DC injection braking time (G16-03,G16-04) or increasing the DC injection braking current (G16-02) can shorten the stopping time. . Refer to the following Fig. 8.1.70, for the DC Injection Braking Operation.

.The DC injection braking operation can be controlled by the Multi-function Digital Inputs by setting G10-01 to 08 to 23 (The DC injection braking command). Refer to Fig. 8.1.37 for the DC Injection Brake Time Chart.

. If G12-05 (Multi-function Analog Input AI2 function selection) or G12-08 (Multi-function Analog Input AI3 function selection) is set to 5(DC injection braking current), the DC injection braking current can be adjusted using the analog input.

. The pre-excitation operation is used to generate the motor magnetic flux before operating machinery requiring high starting torque, particularly with a large-capacity motor.

(1) Maximum Pre-excitation Time (G16-05).

. When the RUN command (Forward or Reverse) is input, the inverter conducts pre-exciting automatically for the maximum time specified by G16-05. . Set the pre-excitation time to start the motor after the magnetic-flux is established at 100% as shown in Fig. 8.1.71 that follows. The build-up time of the magnetic flux may is a function of the electrical time constants of the motor. . The electrical time constant (i.e. the secondary circuit time constant) can be calculated using the motor parameter (Group G07) settings.

Electrical time constant T2=14)-(G7Resistance Equivalent Rotor Motor

13)-(G7Inductance Mutual Motor12)-(G7Inductance Leakage Motor + (sec)

. Set the maximum pre-excitation time (G16-05) around 4-5 times of electrical time constant T2. (2) Pre-excitation Initial Level (G16-06)

. Use the pre-excitation initial level (G16-06) to supply a higher magnetic-flux current within the Maximum pre-excitation time (G16-05). This will increase the speed and stability of the motor’s internal magnetic-flux startup. . To reduce the pre-excitation time (G16-05) in order to establish the magnetic-flux quickly, set the pre-excitation initial level (G16-06) > Motor Excitation Current(G7-06) * Motor Core Saturation Coefficient 3(G07-09).

. If G16-06 is set higher than (G7-06)*(G7-09), a higher exciting current will be supplied during the maximum pre-excitation time (G16-05), and the motor’s internal magnetic flux build-up time can be shortened. If the pre-excitation initial level (G16-06) is set to high value, there may be greater acoustic noise generated from the motor during the pre-excitation time. Referring to Fig. 8.1.71 below, the pre-excitation initial level ends when 100% of the magnetic-flux is established.

. These settings allow the “jumping” of certain frequencies within the inverters’ output frequency range so that the motor can operate without resonance caused by some mechanical systems. . Operation is prohibited within the jump frequency range, but ramp up / ramp down changes during acceleration and deceleration are continuous with no jump. . To disable this function, set the frequency jump point 1 - 3(G17-01 to G17-03) to 0.0Hz. . For the frequency jump point 1 - 3 (G17-01 to G17-03), set the center frequency to be jumped. . For G17-04, set the frequency jump width. The jump frequency ± the frequency jump width becomes the frequency jump range. If G17-04 is set as 0.0Hz, the frequency jump function is disabled. . The relationship between the output frequency and the frequency jump reference is shown as in the following Fig. 8.1.72.

. The Overvoltage Prevention (OVP) function is used to control motor loads when the motor is being Overhauled by the stored energy during part of the machine cycle.

Example: In press application, there are two ways that the motor may be forced overhauled: (1). When the cam clutch is not engaged, the motor can accelerate and drive the flywheel. The inertia from the flywheel will overhaul the motor forcing regeneration into the inverter when the speed of the motor is reduced.

(2). When the cam clutch is engaged, the motor will drive the flywheel to compress the springs, and after the highest point of the cam moves past the center of the cam the springs will begin to release their energy into the flywheel, and overhaul the motor forcing regeneration into the inverter.


8-75

Fig. 8.1.74 Press Operation

. The Overvoltage Prevention (OVP) function monitors and regulates the DC bus voltage by adjusting the deceleration and acceleration rates of the motor to control regeneration. When the speed reference is reduced, the motor starts to decelerate, and when the frequency is constant and regeneration is detected the inverter accelerates the motor to remove the regeneration voltage.

. Refer to the following Fig. 8.1.75, for the OVP operation.

Fig. 8.1.75 OVP Operation 1). The DC bus filter is used to provide a stable bus reference needed to determine sudden changes in the DC bus do to regeneration.

. The DC bus filter buildup rate is adjusted by G18-01 (DC bus filter rise amount). When the DC bus voltage is above the G18-01+G18-03 (DC bus filter deadband), the filter output will increase. . The DC bus filter decrement rate is adjusted by G18-02 (DC bus filter fall amount). When the DC bus voltage is below the G18-02-G18-03 (DC bus filter deadband), the filter output will decrease. . The DC bus filter output can be monitored by U1-60 (DC bus filter value). . Sets the decrement rate of the DC bus filter much faster than the buildup rate (i.e. sets the value of G18-02 higher than G18-01).


8-76

2). When the inverter is running and the frequency reference is constant, the OVP function monitors for the DC bus overshoot (Can be monitored by U1-61). . The DC bus overshoot is multiplied by G18-04 (OVP frequency reference gain) and is converted

into a frequency to accelerate the inverter to prevent regeneration. . The converted frequency may be monitored by U1-62 (OVP frequency), and will be added to the

existing frequency reference. The OVP total output frequency can be monitored by U1-63. . Acceleration will occur when there is a DC bus overshoot (monitored by U1-61), and the rate is

adjusted by G03-01 (Tacc1). . The inverter output will return to the input frequency reference as the overshoot decreases, and

the deceleration rate is determined based on the DC bus voltage as shown in the following Fig. 8.1.76.

Fig. 8.1.76 Deceleration Time of OVP

3). When the inverter is stopped, the deceleration rate is set by G03-02 (Tdec1), and when the inverter decelerates after a DC bus overshoot occurs, it will use the OVP deceleration time as shown in the previous Fig. 8.1.76. . At the DC bus voltage set in G18-06 (OVP Deceleration start voltage), the OVP deceleration rate will be set in G03-06 (Tdec3). . When the DC bus voltage rises above this level, the deceleration will increase as necessary to prevent the DC bus voltage from increasing further. . When the DC bus voltage reaches the setting in G18-07 (OVP Deceleration stop voltage), the deceleration time will be the set value in G03-08 (Tdec4). . The deceleration rate will change linearly along the slope defined by the starting point (G18-06) and the stopping point (G18-07).

4). The OVP function can be disabled or enabled by G18-08. When the OVP function is activated (G18-08=1), the following parameters will be changed to the new defaults:

G02-03=1 (Stopping method : coast to stop). G03-01 (Tacc1) = 5.0 Sec (The frequency reference acceleration rate when there is a DC bus overshoot.) G03-06 (Tdec3) = 20.0 Sec (Lower set point of the OVP deceleration rate). G03-08 (Tdec4) = 100.0 Sec (Upper set point of the OVP deceleration rate). G15-01 = 0.0 Sec G15-02 = 0.0 Sec (S-curve should be off in the OVP function) G15-03 = 0.0 Sec

PID Control Operations

The characteristics of PID control are outlined below:

. P control: This is a proportional input to the control system that is based on the difference (Error) between the input command level (Set-Point) and the actual controlled value (Feed-back). The difference or error is amplified by the (P) section using a settable (Gain) to minimize the error. However as the gain is increased, the system tends toward instability . I control: This allows the proportional gain (P) to be integrated over time so that higher gains may be used thus resulting in smaller errors. However as the integral time (I) is increased, the system response decreases. . D control: This is the opposite effect of integral control and provides the derivative control input of the input error in order to increase the system response. Caution must be used when implementing this parameter as it can cause system instability and is rarely used. . PID control : Optimum control is achieved by combining the best features of P, I ,and D control .

Types of PID Control Two types of PID control are possible with the inverter：

(a) Feedback-Value Derivative PID control：(when G23-01 =-1--B) With feedback-value derivative PID control, the feedback value is differentiated. Response is possible with respect to changes both in target value and the controlled process. To adjust the PID parameters more carefully to keep system stable. Refer to Fig. 8.1.81 for the Feedback-Value Derivative PID Control.

(b)Basic PID control：(when G23-01 = -0--B) When the D control response is adjusted to follow changes in the control in the control object , overshooting and undershooting can occur with changes in the target value . This is the basic form of PID control. Refer to the following Fig. 8.1.82 Basic PID Control.

PID Adjustment Methods

. Use the following procedure to activate PID control and then make adjustments while monitoring the response.

(1) Enable PID Control (set G23-01 to other than “---0B” ) (2) Increase the proportional gain (G23-02) as high as possible without creating instability. (3) Decrease the integral time (G23-03) as low as possible without creating instability. (4) Increase the derivative time (G23-04) as high as possible without creating instability.

. The Proportional (P), Integral (I) and Derivative (D) functions provide closed loop control, or regulation, of a system process variable (pressure, temperature, etc.). This regulation is accomplished by comparing a feedback signal with a set point signal which results in a deviation or error signal (U1-29).The PID control function (algorithm) then performs calculations using the parameter settings of G23-01 to G23-14 and readjusts the reference frequency (Fref). In this way the PID control loop is constantly trying to minimize the error between the set point and the actual value of the process variable. . The PID output polarity can be selected according to G23-01 (setting = --0-B：PID output is forward, setting =--1-B：PID output is reverse ).When the PID output is selected for reverse, if the PID target value increased, the inverter output frequency is lowered . . The PID feedback value can be adjusted by parameter G23-05 (PID feedback gain) and also by adjusting the gain and bias of the analog input used for feedback, terminal (AI2 or AI3), or the pulse train scaling, gain and bias. In PID control, the G23-06 (PID integral limit ) is used to prevent the calculated integral control value from exceeding a specified amount. When the load varies rapidly, the machine may be damaged or the motor may stall due to the inverter response delay. In this case, reduce the set value of G23-06 to speed up inverter response. . The G23-07 (PID limit) is used to prevent the resulting value following the PID control calculation from exceeding a specified amount .The maximum output frequency corresponds to 100%. . The G23-08 (The low pass filter time constant of the PID control output ) is used to prevent load resonance from occurring when the load friction is high, or rigidity is poor. In this case, set the time constant to be greater than the resonance frequency cycle. Increase this time constant to reduce inverter responsiveness. . The G23-09 (PID bias) is need to adjust PID control offset. Set in increments of 0.1%.


8- 85

. The G23-10(PID output gain) is used to adjust the amount of compensation if adding PID control output to the frequency reference as compensation . . When the PID control output is negative, parameter G23-11 (PID reverse output selection) can be used to invert the inverter. However, when reverse prohibit is selected (G02-04=1), the PID control output limit is 0. . The G23-12 (PID target SFS) sets the PID output ramp up and down time to increase or decrease the PID target value. The inverter acceleration / deceleration time is set by G03-01 to G03-08 and is used in conjunction with parameter G23-12. Depending on the settings G03-01 to G03-08, load resonance or instability may occur with PID control. If this occurs, reduce the acceleration / deceleration time (G03-01 to G03-08) until the system is stable, and maintain the required accel / decel time by using G23-12. Parameter G23-12 can be disabled using a Multi-function Digital Input set to 31 (PID target SFS disabled).

PID Fine Adjustment

. All of the PID control setting parameters are interactive, and will need to be adjusted until the control loop is properly tuned, so that stability with minimal steady-state error can be achieved. A general procedure for tuning these parameter is as follows:

(1) Increase or decrease the Proportional (P) gain until instability in the controlled variable is minimized.

(2) The addition of Integral (I) time will decrease system instability as the proportional gain is increased. The time should be adjusted so that the highest proportional gain can be used without causing system instability. However, increasing the time will also decrease the response time of the system.

(3) If necessary, adjust derivative time to reduce overshoot during start-up. The inverter’s acceleration / deceleration time can also be used for this purpose. . First set the individual PID control parameters, and then make fine adjustments as follows:

(1) Reducing Overshooting

If overshoot occurs, shorten the derivative time (D) and lengthen the integral time (I).

(2) Rapidly Stabilizing Control Status

To rapidly stabilize the control conditions even when overshoot occurs, shorten the integral time (I) and lengthen the derivative time (D).

(3) Reducing Long-cycle Oscillation

If oscillation occurs with a longer cycle than the integral time (I) setting, the integral time is too long. The oscillation will be reduced as the integral time (I) is lengthened.

(4) Reducing Short-cycle Oscillation

If the oscillation cycle is short and approximately the same as the derivative time (D) setting, the derivative time is too long. The oscillation will be reduced as the derivative time (D) is shortened. If setting the derivative time (D) to 0.00 does reduce oscillation, then either decrease the proportional gain (P) or raise the PID primary delay time constant.

. When the output frequency (Fout) drops below the PID sleep start frequency set by G23-21, the PID sleep mode timer is started, and the present output frequency will follow the frequency reference (Fref) until the minimum output frequency set by G06-07 (Fmin) is reached. When the time set by G23-22 (PID sleep delay time) has expired, the inverter will ramp down the motor to stop and the inverter stay at the sleep mode. .

KVA A X X X . In the V/F control mode, the Auto Energy Saving (AES) function automatically adjusts an optimum output voltage value to minimize the inverter output current according to the load. The output power savings varies according to the load ratio. When the load ratio exceeds 70% the energy savings is minimum, but as the load becomes lighter, the savings increases. . Since the parameters used in the AES have been preset at the factory to the optimum values prior to shipment, no adjustment is usually necessary under normal operation. If the motor characteristics being used differ greatly from those of TECO standard motors, refer to the following description to adjust the parameters.

(1) Auto Energy Saving Control Mode (G24-01)

. To enable AES control, set G24-01 to 1. (2) Energy Saving Voltage Limit (G24-02 to G24-05)

. Set the upper and lower limits of output voltage using G24-02 to G24-05 as shown in the following Fig. 8.1.88. . If the voltage reference value calculated in the energy savings mode exceeds the upper or lower limit value, this upper or lower limit value is output as voltage reference value. . The upper limit value G24-02 and G24-03 is set in order to prevent over excitation at low frequency, and the lower limit value G24-04 and G24-05 is set in order to prevent stalling at light load. . The Limit voltage values obtained at 6Hz and 60Hz are preset, for any other limit the value can be calculated by linear interpolation. . The setting is made as a percentage of rated output voltage.

. In the AES control mode, the optimum voltage is calculated according to the load power requirements, and this voltage is then supplied to the motor. However, this calculated value may vary due to temperature fluctuations or differences in motor characteristics, therefore the optimum voltage may not be supplied in some cases. To optimize efficiency the optimum voltage can be tuned by the setting the following AES tuning parameters.

a. AES Tuning Operation Voltage Limit (G24-06).

. Limits the range where the voltage is controlled by the tuning operation.

. Set the range to 100% / 230V for 230V class and 100% / 460V for 460V class.

. Set to 0 to disable the tuning operation.

. Refer to Fig. 8.1.89.

b. AES Tuning Operation Control Cycle Time (G24-07).

. Sets the time constant for output power detection.

. To improve response when the load fluctuates, decrease the G24-07 setting.

. If G24-07 is set too small, however, the motor may become unstable when the load is light .

c. AES Tuning Operation Voltage Step (G24-08 , G24-09). . Sets variation width of the voltage for one tuning operation cycle. . Setting is made in % of rated output voltage. . By increasing this value, speed variation becomes larger. . This voltage variation width is set at a tuning starting voltage 100% and 5%. With other voltage values, the voltage variation width can be calculated by linear interpolation is set. Refer the following Fig. 8.1.90.

(4) Energy Saving Coefficient (G24-10). . Voltage at which the motor efficiency will be maximum is calculated by using this coefficient, and the calculated value is the voltage reference. . The value of G24-10 is set at the factory for the motor capacity corresponding to the inverter. If the motor capacity differs, set the motor capacity by using parameter G07-03 (Motor rated output power), and adjust G24-10 until the output voltage reaches the minimum value. .

. Assign the zero-servo command to one of the Multi-function Digital Inputs (G10-01 to G10-08 = 41). The zero-servo function is enabled when the Multi-function Digital Input is on. . When the frequency reference falls below the zero speed level (The larger of G06-07 or G16-01 (DC braking start frequency)), the zero-servo status is implemented (zero-servo start position), and the motor shaft position will be held even though the analog reference input may not be zero. . If the run command is OFF during zero-servo status, the zero-servo function will become ineffective. . To output the zero-servo status, assign the zero-servo completion signal to one of the Multi-function Digital Outputs (G11-01 to G11-04 = 24).

. Use the zero-servo gain G27-01 parameter to adjust the holding torque of the zero-servo operation.

. The holding torque will increase if the set value is increased, but instability can occur if set too high.

. Do not use the zero-servo function to hold the motor for extended periods of time at 100% of inverter rated current, otherwise, an OH5 (IGBT overheat) fault may result. Extended periods of zero-servo holding torque can be achieved by keeping the output current during zero-servo less than 50 to 60% of inverter rated current or by increasing the inverter capacity.

Set the zero-servo count G27-02 to the number of pulses from the PG after multiplied by four. (Four times resolution of the PG by counting the rising and falling edges of phase A and B).

(3) Zero Speed Braking Operation Selection (G27-03). . In the V/f control mode, the DC injection braking operation (without PG feedback) can be used to generate the holding torque. . Set G27-03 to select the zero speed braking operation.

The V/F mode Adjustment procedure of Motor Slip Compensation Gain (G28-01): 1 Correctly set the rated slip (G07-02) and motor no-load current (G07-15 ). 2 Set the slip compensation gain (G28-01) to 1.0 (factory setting is 0.0 for V/f control mode.) 3 Operate with a load, measure the speed and adjust the slip compensation gain (G28-01) in

increments of 0.1. If the speed is lower than the frequency reference, increase the G28-01 setting. If the speed is higher than the frequency reference, decrease the G28-01 setting.

. Slip compensation is enabled when the output current is greater than motor no-load current (G07-15). The output frequency will shift from f1 to f2 for the positive change of load torque. Refer to Fig. 8.1.97. The slip compensation value is as below formula:

[Output Current (U1-03) – Motor No-Load Current(G07-15)] Slip Compensation Value = Motor Rated Slip x

(G07-02) [Motor Rated current (G07-04) – Motor No-Load Current (G07-15)]

Fig. 8.1.98 Slip Compensation Limit

. If the actual motor speed is lower than the frequency reference speed and does not change when the slip compensation gain G28-01 is adjusted, the motor may have reached the slip compensation limit. Make sure the value of slip compensation limit G28-02 and frequency reference do not exceed the tolerance of the machine.

(3) Slip compensation Primary Delay Time (G28-03). . Sets the filter time of slip compensation for V/f mode.

(4) Slip Compensation During Regeneration Selection (G28-04). . Sets whether to enable or disable the slip compensation function during regeneration. . When speed accuracy during motor regeneration (deceleration) is required in SLV control, set G28-04 to 1 (enabled). . The amount of regeneration is momentarily increased when the slip compensation function is used (G28-04 =1), therefore some form braking option (braking unit, braking resistor) may be required.

SLV mode adjustment (1)Slip Compensation Gain (G28-01)

. Set this gain to control the whole range speed accuracy when load is applied.

. If motor speed drops when load is applied at low speed below 2Hz, increase G28-01.

. If motor speed increases when load is applied at low speed below 2Hz, decrease G28-01.

. G28-01 is a fixed slip gain for the whole speed range. it’s common that this gain adjusted at low speed still has a slightly speed drop at high speed. If this speed drop can’t be accepted at high speed, adjust G28-02 to add an additional compensation or just readjust G28-01 for high speed and sacrifice the low speed accuracy.

Th effect of G28-01 on Torque-Speed curve is shown as below:

Fig. 8.1.99 G28-01 effect on Torque-Speed curve

(2)High Speed Slip Compensation Gain(G28-05)

. Set this gain to control the speed accuracy from medium to high speed range when load is applied. Normally it doesn’t need to be adjusted.

. After adjustment of G28-01, increase frequency reference and see whether speed still declines or not. If the loading speed declines as the frequency reference increases, increase G28-05 to compensate the loading speed drop.

. Accelerate to motor rated frequency(G06-04 Base frequency), increase G28-05 until the loading speed drop is zero.

. When motor temperature is hot, loading speed will drop more. It’s better to over adjust G28-05 and G28-01 at cold trial operation to compensate speed drop due to temperature rise.

. In contrast to G28-01, G28-05 is a variable gain to compensate slip for the whole speed range.


8- 95

G28-05 defines the slip compensation gain at motor rated frequency. The whole slip compensation gain then computed as

Slip compensation Gain=LSSlipCmpG+HSSlipCmpG*F/Fr

Where LSSlipCmpG is G28-01, HSSlipCmpG is G28-05, F is frequency reference, Fr is motor rated

frequency defined by G06-04(base frequency). The combination slip compensation gain of G28-01 and G28-05 versus frequency reference is

Fig. 8.1.100 G28-01/G28-05 Slip Compensation Gain vs. Frequency Reference

The effect of G28-05 on Torque-Speed curve is shown as below:

Fig. 8.1.101 G28-05 effect on Torque-Speed curve

(3)FOC(Flux Orient Control) delay time(G28-06)

. In SLV mode, a flux slip compensation was conducted to keep torque current and excitation current decoupled.

. When the motor suffers over 100% load at rated frequency, the voltage drop of inductance and resistance might lead to saturation of inverter output and the coupling of torque current and excitation current and causes hunting. A flux slip compensation will decouple torque current and excitation current so that hunting disappears.

. G28-06 sets the delay time of flux slip compensation.

. Increase G28-06 for slow and stable operation. Decrease G28-06 for fast operation. FOC(Flux Orient Control) Gain(G28-07)

(4)G28-07 sets the gain of flux slip compensation.

. If motor hunts at motor rated frequency and full load, set G28-07 to zero and gradually increase until the hunting is reliefed.

. The following figures show the structure of the speed control loop(ASR).

(a) V/f + PG Control Mode: . The speed control (ASR) adjusts the output frequency so that the deviation between the frequency

reference and the speed feedback approaches 0. . ASR integrator output can be limited or cleared. The whole ASR output also can be limited.

. When one of the Multi-function Inputs (G10-01 to G10-08) is set to 37 (PG invalid), the input can be used to enable or disable the speed control loop(ASR).


8- 98

(b) SLV Control Mode: . The speed control adjusts the torque reference so that the deviation between the frequency reference

and the speed observer feedback(PG feedback) is 0. . SLV mode ASR controller has a speed observer that estimates motor speed from motor voltage and

current. In order to reduce noise on speed feedback and improve the speed accuracy, a low pass filter and a speed feedback compensator are used.

. ASR integrator output can be limited or cleared. The whole output has a low pass filter for primary delay. Torque reference is also limited.

Refer to the following Fig. 8.1.106. Cont.

(2). Adjust Speed Control (ASR) Gain: Use the following procedure to adjust the gain with the actual load connected

a. Gain Adjustments at Minimum Output Frequency G30-03 and G30-04. . Run the motor at the minimum output frequency. . Increase the ASR proportional gain 2 G30-03 as high as possible without creating instability. . Decrease the ASR integral time G30-04 as low as possible without creating instability. . Monitor the inverter output current and verify that it is less than 50% of the inverter rated current. If the output current exceeds 50% of the inverter rated current, decrease G30-03 and increase G30-04.

b. Gain Adjustments at Maximum Output Frequency. G30-01 and G30-02. . Run the motor at the maximum output frequency G06-03 (Fmax). . Increase the ASR proportional gain 1G30-01 as high as possible without creating instability. . Decrease the ASR integral time 1G30-02 as low as possible without creating instability.

c. Gain Adjustments for Integral Control during Acceleration / Deceleration G30-08. . Enable the integral control during acceleration / deceleration by setting G30-08=1 (enabled) when it is desired to closely follow the frequency reference during acceleration and deceleration. . The integral control causes the motor speed to reach the target speed as fast as possible, but may result in overshoot or undershoot per the following Fig. 8.1.107.

Fig. 8.1.107 Motor Speed and ASR Gain Adjustments . When one of the Multi-function Digital Inputs(G10-01 to G10-08) is set to 38 (Speed control integral

reset), the input can be used to switch the speed control loop (ASR) between P control and PI control. Refer to Fig.8.105. P control (integral reset) is used when the Multi-function Digital Input is on.

If overshooting occurs(), decrease G30-01(ASR proportional gain 1) and increase G30-02 (ASR integral time 1).

If undershooting occurs(), decrease G30-03(ASR proportional gain 2) and increase G30-04 (ASR integral time 2).

If the overshooting or undershooting can not be eliminated by the gain adjustments as above, decrease the ASR +/- limit (G30-06 / G30-07) to lower the frequency reference compensation (Δf) limit. Since G30-06 / G30-07 can not be changed during operation, stop the inverter first


8- 100

and then decrease the ASR +/- limit. . Make the related parameter settings as shown in the following Fig. 8.1.108 and observe the motor speed waveform while making the gain adjustments.

Fig. 8.1.108 Analog Output Setting for Motor Speed Observation

d. ASR +/- Limit (G30-06 , G30-07) . The ASR +/- limit is the frequency limit for compensation by speed control. Set this frequency limit as a percentage of the maximum output frequency G06-03. . If the frequency limit is lowed too much, the actual motor speed may not reach the target speed. Verity that the target speed is reached during normal operation. B. ASR Setting in SV/SLV Control Mode

(1). SLV Gain setting: . The SLV mode speed control controller has high speed gain G30-01/G30-02 and low speed gain

G30-03/G30-04 PI parameters for High speed and Low speed region, respectively. ASR uses frequency reference as the reference of gain switching. The switching point between high speed and low speed is set by G30-16 and G30-17.

. Similar to ASR gain, speed observer has high speed gain G30-10/G30-11 and low speed gain G30-12/G30-13 PI parameters. Gain switching also depends on frequency reference. The switching point are also set by G30-16 and G30-17.

. Speed observer has a low pass filter to reduce noise on speed feedback. G30-14 and G30-15 defines the high speed and low speed low pass filter time constant, respectively. Gain switching also depends on frequency reference. The switching point are also set by G30-16 and G30-17.

. G30-18 set the low speed compensation gain for speed feedback.

. G30-19 set the High speed compensation gain for speed feedback.

. When the frequency reference greater than G30-17, high speed ASR/Observer gains and the low pass filter time constant will be fully applied. When the frequency reference less than G30-16, low speed ASR/Observer gains and the low pass filter time constant will be fully applied. When the speed command falls between G30-17 and G30-16, gains and time constant will be linearly and smoothly switched. To avoid unwanted gain calculation error, G30-17 should be 4Hz greater than G30-16.

Fig. 8.1.109 ASR Gain Settings in SLV mode (2) SV Gain setting:

. In the SV mode, Only G30-01 and G30-02 set the proportional(P) gain and integral(I) time for full range speed operation.

(3) Adjust Speed Control(ASR) Gain： . Using the Multi-function Analog Output(terminals AO1 and AO2) to monitor both the output frequency

and motor speed(as above Fig. 8.109 ) When you make finer gain adjustment.

①. SV mode for full range speed Gain Adjustments (G30-01 , G30-02) . Adjust these parameters at normal operating speed. . Increase the ASR proportional gain 1 (G30-01) as far as possible without creating oscillation. The G30-01 setting adjusts the responsiveness of the speed control loop. The responsiveness is increased when increasing the G30-01 setting, but oscillation will

occur if the setting is increased too much. Increase the setting for larger loads. Refer to the following figure.

Fig. 8.1.110 Responsiveness for ASR Proportional Gain 1

. Decrease the ASR integral time 1(G30-02) as far as possible without creating oscillation Lengthening the integral time 1 lowers the responsiveness, and weakens the resistance to

external influences. Oscillation will occur if the G30-02 setting is too short. Refer to the following figure.

. If there’s excessive overshoot during tuning of ASR PI gain, an alarm of over voltage may occur. Put a regeneration resistor to absorb the overshoot.

Fig. 8.1.111 Response for ASR Integral Time 1

②. SLV mode Gain Adjustments(G30-01~G30-04 , G30-10~G30-19) . Adjust Low speed ASR PI gain G30-03~G30-04 at a frequency reference below G30-16. The

P gain and integral time adjustment are similar to G30-01 and G30-02 at SV mode. . Adjust High speed ASR PI gain G30-01~G30-02 at a frequency reference above G30-17. The

P gain and integral time adjustment are similar to G30-01 and G30-02 at SV mode. . Normally low speed ASR gain can be the same as high speed ASR gain. Adjust low-speed

and high-speed gain only when oscillation occurs because of resonance with the mechanical system at low-speed or high-speed.

. If a faster response can’t be obtained by adjusting the ASR PI gain G30-01~G30-04, decrease low pass filter time constant G30-14~G30-15 to increase speed feedback bandwidth and readjust ASR gain.

. Adjust Low speed low pass filter time constant G30-15 at a frequency reference below G30-16.

. Adjust High speed low pass filter time constant G30-14 at a frequency reference above G30-17.

. Increasing low pass filter time constant could limit the speed feedback bandwidth and slows whole system’s fastest response. This can reduce the speed feedback noise but weaken the capability of withstanding impact load. If the system load is slow varied and need a stable operation, this adjustment can be applied. A lower bandwidth of the speed feedback must be accompanied with a lower gain of ASR to guarantee a stable operation.

. Decreasing low pass filter time constant could lift the limitstion of the speed feedback


8- 102

bandwidth and increase whole system’s fastest response. This can increase the speed feedback noise but strengthen the capability of withstanding impact load. If the system load is fast varied and need a fast operation, this adjustment can be applied. A high bandwidth of the speed feedback allows a higher gain of ASR.

. If a faster response still can’t be obtained by adjusting the ASR PI gain G30-01~G30-04 and low pass filter time constant G30-14~G30-15, The adjusment of speed observer PI gain G30-10~G30-13 is needed.

. A high gain of speed observer(larger P gain and smaller integral time) could increase bandwidth of speed feedback but also increase noise and cause instability.

. A low gain of speed observer(smaller P gain and larger integral time) could decrease bandwidth of speed feedback but also decrease noise and increase stability.

. Normally, the adjustment of ASR is enough for most of application. The adjustment of low pass filter time constant and speed observer is complex ,riskful and not recommanded. It’s very hard to cover both fast response and stable operation. If both fast response and stable operation are demanded and can’t be done with all SLV mode adjustment, use SV mode.

. G30-16 defines low speed of the gain switching frequency and G30-17 defines high speed of the gain switching frequency.

. At speed below G30-16, inverter outputs more excitation current for precise low speed operation. When the frequency reference is higher than G30-17, inverter output rated excitation current under No-load voltage(T-10).

. Normally G30-16 should be set to 5~50% motor base frequency. If this value is too large, inverter output might saturated. G30-17 should be 4Hz higher than G30-09.

. If heavy load(over 100%) operation is stable at medium speed but hunting at high speed, decrease No-load voltage(T-10) or adjust FOC parameters G28-07~G28-08).

. G30-18 and G30-19 compensate speed feedback at low speed and high speed, respectively.

. Set G30-18 to adjust No-load speed at speed below 2Hz. The adjustment of G30-18 is similar to adding an offset to the Torque-Speed curve. When the No-load speed is lower than frequency reference, increase G30-18. When the No-load speed is higher than frequency reference, decrease G30-18. The effect of G30-18 on Torque-Speed curve is shown as below:

Fig. 8.1.112 G30-18 effect on Torque-Speed Curve

. Set G30-19 to adjust No-load speed from medium to high speed range. Normally it doesn’t need to be adjusted. G30-19 is similar to G30-19, its effect on Torque-Speed curve is

Fig. 8.1.113 G30-19 effect onTorque-Speed curve

③. ASR Primary Delay Time (G30-09).

. Adjustment is not normally required. . A high G30-09 setting lowers the speed responsiveness, but make it difficult for oscillation to

occur.

Reverse: The motor shaft rotates in the C.W (clockwise) direction with a inverter reverse Run command.

. The phase leading for a typical PG is determined as follows phase A leads when the PG rotates C.W(clockwise). As shown in the following Fig 8.1.116.

Fig. 8.1.116 PG Rotation Direction (6). PG Pulse Monitor Output Dividing Ratio (G31-11).

. Set the output ratio using G31-11 when the pulse output signal is connected to a pulse input device. . The set value in G31-11 is expressed as n for the first digit (0 or 1) and k for the second three digits (001 to 320). The output ratio is calculated from n and k with the following equation： G31-11 = , setting ranges n : 0 to 1 n k k : 01 to 32 Output Ratio = (1+n)/k

The possible output ratio settings are as follows : 1/32 - 1

e.g. G31-11=001 → n=0, k=1, ratio = (1+0)/1=1 ①. G31-11=032 → n=0, k=32, ratio = (1+0)/32=1/32 ②. G31-11=132 → n=1, k=32, ratio = (1+1)/32=1/16

. Set the PG output ratio (G31-11) to insure the PG pulse output from terminal PO1 or PO2 is less than 300KHz. (i.e. PG input pulse × PG pulse output ratio ≤ 300KHz). PG-O/PG-L card can output ratio using G31-11 when the pulse output signal, need both A/B

(7). Setting the Number of Gear Teeth PG and Motor (G31-12 , G31-13). . In V/f + PG control mode, the motor can be operated even if there is gearing between the motor and PG. (The speed response of V/f + PG mode is less than SV mode). . Set the number of teeth if there are gears between the motor and PG as follows: Set the no. of gear teeth on load side(PG side) using G31-13 (number of PG gear teeth 2). Set the no. of gear teeth on motor side using G31-12 (number of PG gear teeth 1). The motor speed will be calculated within the inverter using the following equation:

(1). Torque Control Selection (G32-01).

. In the SV control mode, it is possible to switch between speed and torque control using either of The following:

①. Using the Multi-function Digital Input terminals by setting one of the G10-01 to G10-08 parameters to 39, (speed / torque control change). The speed control is performed when the terminal input is off, and torque control is performed when the terminal input is on.

②. Set G32-01 to select speed or torque control. G32-01=0: Speed control (Controlled by G30-01 to G30-10), ASR settings. =1: Torque control (Controlled by G32-02 to G32-05), torque control settings.

. Refer to chapter G8.1.30 for more details regarding speed control structure. . Refer to the following Fig. 8.1.117 for the torque control structure.

(2). Torque Reference Setting(G32-02). (a) Torque Reference Command (Tref) Input (AI2：G12-04, G12-05, AI3：G12-08, G12-09). . The torque reference (Tref) cannot be set with Digital Operator. . The torque reference (Tref) can be adjusted according to the Multi-function Analog Inputs (AI2 or AI3) by setting G12-05 (AI2 function selection) or G12-09 (AI3 function selection) to 17 (torque reference) or 18 (torque compensation). . Refer to the following Table 8.1.16 for the torque reference input methods.

(4 - 20mA) AI3 (SW1-3=” I ”) G12-09=17 AI3 used as torque reference input

. The direction of the motor torque output is determined by the sign(or polarity) of the analog input signal (AI2 or AI3). It is not determined by the direction of the run command .i.e. :

①. Torque reference (Tref) = Positive voltage (or current). Forward torque reference (counterclockwise as viewed from the motor output axis). ②. Torque reference (Tref) = Negative voltage. Reverse torque reference (clockwise as viewed from the motor output axis).

Since the polarity of analog input determines the direction, only a forward torque reference can be input when the signal level of terminal AI2 or AI3 is selected as 0 - 10V(setting value=0) or 4 - 20mA(setting value=2). To apply a reverse torque reference, use a signal level of –10V to 10V or switch the polarity using a Multi-function Digital Input by setting one of the G10-01 – G10-08 parameters to 40 (Polarity reversing command for external torque reference). (b) Torque Reference Filter Primary Delay Time (G32-02). . This time constant is used to eliminate noise in the torque reference signal and adjust the response. . Increase the setting if instability occurs during control.

(3). Speed Limit Input Setting (G32-03 and G32-04). . If the external torque reference and load are not balanced during torque control, the motor will accelerate in either the forward or reverse direction. The speed limit function is used to keep the motor speed from exceeding the specified limit. . There are two ways to set the speed limit; a parameter setting or an analog input value. Refer to The following Table 8.1.17 for the speed limit input methods.

The direction in which speed is controlled is determined by the sign of the speed limit signal: 1. Positive voltage applied: Forward rotation; speed is limited in the forward direction (G32-04

+ G32-05). Reverse rotation; speed is limited in zero or reverse direction (-G32-05). 2. Negative voltage applied: Reverse rotation; speed is limited in the reverse direction

(-G32-04 - G32-05). Forward rotation; speed is limited in zero or forward direction (G32-05). The speed limit value is zero for a motor rotation opposite to the speed limit direction. e.g. When a + voltage is input and the forward run command is on, the effective range of the torque control is from zero to the speed limit value in the forward direction (If the speed limit bias is set to 0).

(4). Speed Limit Bias Setting (G32-05).

. The speed limit bias (G32-05) is used to adjust the margin for the speed limit. . The speed limit bias (G32-05) can be set to limit both the forward and reverse motor speed to the same value. . Set the speed limit bias as a percentage of the maximum output frequency(G06-03). Example 1- Set 30% forward and reverse speed limits.

Fig. 8.1.118 Speed Limit Setting (Example 1) Example 2- Set : 1 speed limit value (G32-04)=100% (forward speed limit) 2 speed limit bias (G32-05)=20%

. The speed range of the torque control is from –20% (set by G32-05) to 120% (the setting value of G32-04 + 32-05).

(6). Setting the Torque Compensation (AI2: G12-04 and G12-05; AI3: G12-08 and G12-09) . The torque compensation (Tcomp in Fig 8.116 ) is added to the torque reference to compensate

for the amount of torque loss from the mechanical loss or other load factors. . Set Multi-function Analog Input AI2 or AI3 as a torque compensation input terminal by setting G12-05=18 or G12-09=18. . Set the proper signal level for the required torque compensation. The direction of the torque compensation is determined by the sign (or polarity) of the input and is not determined by the direction of the run command.

i.e. 1 Tcomp = + Voltage (or current): Forward torque compensation (Counterclockwise as viewed from the motor output axis).

2 Tcomp =－Voltage (or current): Reverse torque compensation (Clockwise as viewed from the motor output axis)

Since the polarity of analog input determines the direction, only forward torque compensation can be input when the signal level of terminal AI2 or AI3 is selected as 0 - 10V (G12-04 or G12-08=0) or 4 - 20mA (G12-04 or G12-08=2). To input reverse torque compensation (Tcomp), be sure to select the –10V - 10V signal level (G12-04 or G12-08=1).

. The over-torque detection function detects excessive mechanical load from an increase in the inverter output current or motor output torque. The under-torque detection function detects a sudden decrease of the mechanical load (e.g. broken belt) from a decrease in the inverter output current or motor output torque. . The settings in the torque detection parameters (G33-01 and G33-04) determine whether over-torque / under-torque conditions will be detected and the kind of processing that will be performed. . The over-torque / under-torque detection level settings depend on the control method.

(1) Inverter output current for V/f control or V/f+PG control mode, 100% of inverter rated output current.

(2) Motor output torque for vector control SLV or SV control mode, 100% rated torque. . The over-torque / under-torque detection signal can be output to Multi-function Digital Output terminals (R1A-R1C, R2A-R2C, R3A-R3C and R4A-R4C) by setting one of the parameters G11-01 to G11-04 (Multi-function Digital Output terminals function selection) to 11, 12, 13 or 14.

. Setting the torque limit function limits the torque applied to the load, or limits regeneration value.

. When the torque limit function is used, the torque control has priority and the motor speed control command and compensation will be disregarded hence, the accel / decel times may be lengthened and motor speed reduced. . There are two ways to apply torque limit:

1 Setting torque limits using parameters (G33-07 to G33-10). 2 Setting torque limits value using an Multi-function Analog Input (AI2 or AI3).

(1). Setting the Torque Limit Using Parameters (G33-07 to G33-10) . There are four torque limits that can be set separately: positive drive, negative drive, forward regeneration and reverse regeneration. Refer to the following Fig. 8.1.126 below.

(2). Setting the Torque Limit Using Multi-function Analog Inputs (G12-05 or G12-09) . The Multi-function Analog Inputs (AI2 and AI3) can be used to limit torque. Use either or both of these inputs a needed by setting parameter G12-05 (AI2 function selection) and G12-09 (AI3 function selection). Refer to the following Table 8.1.19 for the settings related to the torque limit function. Table 8.1.19 Torque Limit Using Analog Input

G12-09 (AI3) setting

Function

13 Positive Torque Limit 14 Negative Torque Limit 15 Regeneration Torque Limit (both the forward and reverse). 16 Positive / Negative Side Torque Limit (Limit torque in both

the forward and reverse direction). . Set the analog input terminal’s (AI2 or AI3) signal level (G12-04 or G12-08) , Gain (G12-06 or G12-10) and bias (G12-07 or G12-11) to match the actual input signal. The analog input terminal signal level is factory set as follows:

1AI2 = 0 to 10V (A 10V input limits the torque to 100% of the motor rated torque). 2AI3 = 4 to 20mA (A 20mA input limits the torque to 100% of the motor rated torque).

. The following Fig 8.1.127 shows the relationship between the output torque and each torque limit.

Fig. 8.1.127 Torque Limit by Analog Input (AI2 or AI3)

When the positive torque limit has been set (setting value = 13), the analog input signal acts as the limit value for positive torque. The positive torque limit input is effective when torque is generated in the positive direction even if the motor is operated in the reverse direction (i.e. regenerative torque in 2nd quadrant). When the negative torque limit has been set (setting value = 14), the analog input signal acts as the limit value for negative torque. The negative torque limit input is effective when torque is generated in the negative direction even if the motor is operated in the forward direction (i.e. regenerative torque in 4th quadrant). When the regenerative torque limit has been set (setting value = 15), the analog input signal acts as the limit value for the forward (4th quadrant) or reverse (2nd quadrant) regeneration region. When the positive / negative side torque limit has been set (setting value = 16), the analog input signal acts as the limit value for positive or negative. The torque limit is 100% of the motor rated torque when the analog input is at its maximum value (10V or 20mA). To increase the torque limit above 100%, set the input terminal’s gain (G12-06 for AI2, and G12-10 for AI3) above 100%. e.g. a gain of 200.0% would result in a torque limit of 200% of the motor rated torque with a 10V or (20mA) analog input.

. Even if a temporary power loss occurs, the inverter can be restarted automatically after power is restored to continue motor operation by setting G36-01 to 1 or 2.

1 G36-01 = 0: When the momentary power loss exceeds 15ms during operation , a “UV” fault (main-circuit Under-voltage) will be detected. 2 G36-01 = 1: When power is restored within the time set in G36-02 (Momentary power loss ride-thru time), the

inverter will restart. If the time set in G36-02 has expired ,a “UV” fault (main-circuit under-voltage) will be detected.

3 G36-01 = 2: When the main power supply is restored before the control power (i.e. the power supply to the control board), the inverter will restart, and “UV” fault (main - circuit under-voltage) will not be detected.

. To continue inverter operation after power has been restored (G36-01 = 1 or 2 ), the run command must be Maintained throughout the ride-thru period. . Fault contact output signals are not output during momentary power loss. . Upon detecting momentary power loss, the inverter shuts off output and maintains the baseblock state for a given period of time. Set a time in G36-03 when the residual voltage is expected to be almost zero. . When momentary power loss time is longer than the minimum baseblock time(G36-03), speed search operation is Started immediately after power recovery. Refer to the following Fig. 8.1.129.

Fig. 8.1.129 Minimum B.B Time and Momentary Power Loss Time

. The minimum baseblock time (G36-03) is also used with the speed search and DC injection braking functions. 1 Set the required minimum baseblock time (G36-03) in order for the residual voltage to dissipate. 2 Increase the setting if an over-current “OC” trip occurs when the speed search or DC injection braking function starts. 3 This setting is activated for speed search performed after a momentary power loss and normal speed search.

. The speed search function is used to find the actual speed of a coasting motor, and smoothly start up from the detected speed. It is effective in situations such as switching from a commercial power supply, power loss ride-through and fault restart. . If speed search during startup is selected in the V/f +PG or SV control mode (control methods with PG ), the inverter will start from the frequency detected by the PG. The speed is estimated every time from start when a run command is input. Therefore, starting is enabled even if the motor idles or runs in the reverse direction when the power supply is turned on. . Set either of the external speed search commands 1 or 2 by one of the Multi-function Digital Input terminals. The external speed search command 1 (set value = 26) and 2 (set value = 27) cannot be set at the same time otherwise , a “SE02”, (DI Terminal Error) warning may occur. . If performing speed search using external speed search commands, add an external sequence to make sure that the Run command must be performed after or at the same time with the speed search command. A typical operation sequence is shown in the following Fig. 8.1.130.

Fig. 8.1.130 Speed Search and Run Command

. Speed search cannot be used for multi-motor drives, motors with two or more frames smaller than the inverter capacity or high-speed motor.

. When using V/f mode, always perform stationary autotuning.

. When using SLV control mode, always perform rotational autotuning, If the cable length between the motor and inverter is changed after autotuning, perform stationary autotuning for motor line- to-line resistance R1 again.

. Speed search uses current detection method. G36-09 defines whether to detect direction. When 1 G36-09=1, bidirection search is enabled:

. At first, the current controller sends a step current set by G36-04 to detect direction. When the direction is determined, the current controller sends a speed search current set by G36-05 and search motor speed from the frequency when the temporary power loss was detected (external speed search command 1, by setting one of G10-01 to G10-08 = 26 ), or from the highest frequency (external speed search command 2, by setting one of G10-01 to

G10-08 = 27). Refer to Fig. 8-130 for Bidirection Speed Search. 2 G36-09=0, bidirection search is disabled:

. The current controller bypasses direction search and sends speed search current in the speed command direction to search motor speed. Make sure the speed of a coasting motor is the same with the speed command.


8- 117

. When Speed Search doesn’t complete normally(For example, motor speed is too slow to be deteced), a Speed Search Time Out alarm will appear. If this situation apears frequently, please set G16-04 to use DC brake function to stop motor and then restart.

(1). Direction Search Operating Current (G36-04)

. Only used for bidetection speed search(when G36-09 = 1)

. Set the direction detect current level.

. Increase this value if direction search failed in low speed(above 5Hz) coasting. Note that larger value could cause slightly DC brake effect.

(2). Speed Search Operating Current (G36-05)

. Used for both bidirection(G36-09=1) or single(G36-09=0) direction speed search method.

. Set the speed search current level.

. Set this value below Exicitation Current(G07-06) which is equal to No-Load current. If No-Load current is unknown, 20% would be a good start. Too big speed search current will cause inverter output saturation and over magnetizing when speed is matched.

start is needed.

(4). Speed Search Delay Time (G36-07) . If the inverter output is equipped with a contact, set the contact operating delay time inG36-07

(speed search delay time). . The factory setting is 0.2 sec, after waiting for speed search delay time, the inverter starts

thespeed search operations. Set G36-07 = 0.0 sec when the contact is not need.

(5). Voltage Recovery Time (G36-08). . Set the time allowed for the normal voltage to be restored after completion of the speed search. . This is the time for voltage to be restored from 0 to 230Vac for 230V class inverter(0 to 460Vac for

460V class inverter)

(6). Bidirection Speed Search Selection (G36-09) . =1 enable bidirection speed search. =0 disable bidirection speed search. . When bidirection speed search is disabled, speed search direction depends on speed command.

- Using The RTC Timer Functions


8- 126

. A timer can be connected to multiple time periods and a time period can be set in multiple timers.

. The timer is configured in four steps: Step1: Enable the timer Configure how the timer is enabled (by G42-04). Step2: Setting the time period Set the time, day and/or offset time when the timer operates by G42-05 to G42-22. If any start time is the same as the corresponding stop time, the timer period is disabled. Ex, G42-05 (start time 1) = G42-06 (stop time 1) means time period is disabled. Step3: Creating the timer Assign the selected time period to a specific timer by G42-23 to G42-26. Step4: Connecting the parameters Connect selected parameters to the timer. A parameter can be connected to only one timer. (e.g. G11-01 to 04, and G42-27) . Refer to Fig. 8.1.139, RTC Configuration.

. The Run Direction Selection (G42-28) provides 4 RTC RUN directions.

Bit 0 of G42-28 (---X) is RTC Run 1. 0 is FWD and 1 is REV. Bit 1 of G42-28 (--X-) is RTC Run 2. 0 is FWD and 1 is REV. Bit 2 of G42-28 (-X--) is RTC Run 3. 0 is FWD and 1 is REV. Bit 3 of G42-28 (X---) is RTC Run 4. 0 is FWD and 1 is REV.

. If G42-27 is set to 1 to 4 and the RUN command is on, the RUN direction is set by RTC Run 1 and the specified timer will determine the inverter status

Table 8.1.21 Inverter Status for G42-28 = 1 to 4

Run Command

RTC Timer x Status Inverter Status

0 0 The inverter will not Run (no Run command). 0 1 The inverter will not Run (no Run command). 1 0 The inverter will not Run (RTC timer deactivated). 1 1 The inverter will Run. The Run direction is set by RTC Run 1 (0 for FWD, 1

for REV) 0: Deactivated; 1: Activated

RTC Timer x is the RTC timer specified by G42

. If G42-27 is set to 5 and the RUN command is on, the frequency reference and RUN direction is selected by the combination of the activated timer 1 and 2, refer to the following Table 8.1.21.

When G02-01 = 1 (freq. ref input = AI1 or AI2), the frequency reference is input from the analog command through terminals AI1 or AI2. *2. When G12-09 = 0 (AI3 function selected as auxiliary speed frequency), the frequency ref. is input from the auxiliary analog input AI3. When G12-09 ≠ 0, the frequency ref. is input by the setting of G05-02 (freq. reference 2).

. Application Example:

The following example shows how an RTC timer is used and connected to different parameters. In this example, the timer will be set to function from 6AM to 10PM on Monday, 8AM to 8PM between Tuesday and Friday, 8AM to 12AM on Sunday, and the motor is operated at speed 1 on weekdays (from Mon to Fri) and speed 2 on weekends (Sat and Sun).

. The traverse operation is defined as adding a triangular wave to the basic inverter output frequency at the preset wobble time. This function is primarily used for synthetic yarn winding applications to move the yarn back and forth in a diamond pattern across the surface of the yarn package. . The traverse operation is active only by selecting the V/f and V/f +PG control mode. To compensate for the inertia in the system a quick frequency jump can be included. . If any functions below is set, the traverse function is ineffective 1. frequency reference and Run direction is controlled by RTC timer (G42-27 = 1 to 5) 2. Auto-Run Function (G05-36 = 1 to 6)

. If the traverse function is set, the PID function is ineffective

. Refer to the following Fig. 8.1.142, for the traverse operation and related parameter settings.

Fig. 8.1.142 Traverse Operation and Related Parameters

.The traverse operation is enabled when one of the Multi-function Digital Inputs (G10-01 to G10-08) traverse run is set to 32 (Traverse run) and the inverter RUN command are input. The traverse operation is ready when the inverter output frequency reaches center frequency (G47-01). During acceleration the to center frequency, the acceleration time is the original preset acceleration time (Tacc 1 to Tacc 4). When the traverse operation is off or the RUN command is removed, the deceleration time is also the original preset deceleration time (Tdec 1 to Tdec4). However, in the traverse operation, the inverter is operated at the wobble time (G47-05, tup + tdown) and wobble ratio (G47-06, tup / tdown). . Set the Multi-function Digital Output terminals (R1A-R1C, R2A-R2C, R3A-R3C or R4A-R4C) to output the traverse-up (During the acceleration period) through setting G11-01 to G11-04 to a value of 20 or 21. . Refer to the following Fig. 8.1.143 for the traverse ON/OFF control.


8- 144

Fig. 8.1.144 Traverse ON/OFF Control

. During the traverse operation, the center frequency could be controlled by one of the Multi-function Digital Inputs. However, the upper deviation traverse run (G10-01- 08 = 33) and lower deviation traverse run(G10-01- 08 = 34) command can not be input at the same time, otherwise the inverter will maintain the original center frequency (G47-01). Refer to the following Fig. 8.1.145.

Fig. 8.1.145 Upper/Lower Deviation Traverse Operation

. The stall prevention function is idle in the acceleration and deceleration period of the traverse operation. However, it is in effect during the first acceleration to center frequency (G47-01) process when the traverse function is off or when the inverter is in the deceleration period after the run command is removed. This must be taken into consideration when selecting the proper inverter capacity to comply the actual system requirements when designing the equipment. . The frequency range of traverse operation is restricted by the inverter frequency upper bound (G05-18) and lower bound (G05-19). If the (center frequency + amplitude) is larger than the frequency upper bound (G05-18), it will operate at the upper bound (G05-18), and if (center frequency - amplitude) is less than the frequency lower bound it will operate at the lower bound. . During traverse operation, all of the parameter values (G47-01 to G47-08) can be modified.

. The bigger the motor is, the more the No-Load voltage is.

. Smaller No-Load voltage will reduce No-Load current, weaken the flux and increase current when load is applied.

. Larger No-Load voltage will increase No-Load current, enhence the flux and reduce current when load is applied. The enhenced flux also cause larger back electromotive force which saturates inverter output and makes torque control failed.

Motor No-Load Curr. (T-11) . Motor no load current is for SV or SLV mode and stationary autotune (T-01 = 1) only. Set this value as the no-load current of the motor,

. If this parameter is not set, the inverter will use the internal no-load current data to calculate motor parameters.

Long wire between motor and inverter . When the wire between motor and inverter is longer than 50m, always perform stationary autotuning for

long cable (T-01=2). For better vector control performance, use short wire and perform rotational autotuning (T-01=0) first, then use the long wire and perform stationary autotuning for long cable (T-01=2) again.

. If rotational autotuning (T-01=0) can’t be performed, input mutual inductance(G07-15), excitation current(G7-07), core saturation compensation factor 1~3(G07-08~G07-10) manually.

.For V/F control with long motor cable always perform stationay autotuning.

9. FAULT MESSAGE AND TROUBLESHOOTING 9.1 General

The Inverter has fault detection and warning / self- diagnostic functions. When the Inverter detects a fault the fault code is displayed on the Digital Operator, the fault contacts output operate, and the inverter output voltage goes to zero causing the motor to stop. The stopping method can be selected for some faults.

When the inverter detects a warning / self-diagnosis, the Digital Operator will display the warning / self-diagnostic code, however the fault output contacts do not operate. The system will automatically returned to its original status once the cause of the alarm has been removed.

9.2 Fault Detection Function

Table 9.2.1 below shows the LCD displayed fault, with possible causes and corrective actions. One of the following methods can be used to reset the fault after restarting the Inverter:

1. Set one of the Multi-function Digital Input terminals (G10-01 to G10-08) to 3 (Fault Reset) and turn it on, or press the RESET key on the Digital Operator.

10.3.1. PG Interface for Terminal Cards TER-001.

A. PG Interface Card TER-001 wiring. The built-in PG interface of terminal card TER-001 only allows a single A/B phase open-collector / complementary interface. The wiring and terminal specifications are shown in the following Fig. 10.3.1.

Fig. 10.3.1 PG Interface on TER-001

1 Shielded twisted-pair cables must be used for signal lines, and the shield connected terminal (E). 2 The signal lines should not exceed a maximum of 100 meters, between the PG and inverter and kept separate from power lines. 3 Do not use the pulse generator for anything other than the PG (encoder). 4 The direction of rotation of the PG can be set in G31-10. The factory default is A-phase leads B-phase by

90° for forward rotation. The PG phase-A or B pulse can be monitored using the pulse output terminal PO1 (Set G14-06 to 07) or PO2 (Set G14-08, to 09), and G31-11 for the pulse output ratio.

5 Place the shorting pin of JP3 on ‘+5V’location when using the internal +5V as PG power supply and on ’+12V’ for +12V PG power supply.

11. DERATING GUIDELINES

The inverter is designed for the maximum ambient operating temperature of 45°C without derating using the factory default setting for the carrier frequency (G04-01). If the carrier frequency is set higher than the factory setting or the operating ambient temperature is higher than 45°C, the inverter rated output current will need to be reduced. Refer to the following carrier frequency vs. rated output current de-rating curves.

If multiple braking units are being installed, the master/slave jumper of braking unit must be selected, refer to Braking Unit Installation Manual for more details. 12.4 Sinusoidal Output Filter

Since there is inductance (L) and stray capacitance (C) in wiring between the inverter and the motor, the peak value of the voltage on the motor terminals can reach up to twice of the inverter DC voltage (√2 × 460V × 2 = approx.1300V for an input voltage of 460Vac) depending on the switching speed of the inverter elements and the wiring. The surge voltages originating in the LC resonance of the wiring may be applied to the motor input terminals and can sometimes cause damage to the motor insulation. Installing an AC reactor on the output side of the inverter can reduce the voltage (dv/dt) however, if the wiring length becomes too long, suppressing the peak voltage due to surge voltage may be difficult. Installing a sinusoidal output filter on the output side of the inverter, results in the reduction of the peak value of the motor terminal voltage. Refer to Table 12.4.1 below for the sinusoidal filter selection. The sinusoidal filter is not needed for the 230V class inverters due to the lower peak voltage on the motor terminals.

Notes 1 - The V31 inverter utilizes improved latest generation IGBT devices and soft-switching gate control circuits. This improves the dv/dt by approximately 50% compared to the previous model, which in turn reduces the motor peak terminal voltage. 2 - The purpose of sinusoidal output filter is: . Increased motor service life. . Reduction of parasitic motor noise. . Reduced pulse load of the inverter. . Improved system reliability & efficiency. Connection Example:
