OUT

LINE

(3) Dust, dirt, oil mist

Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cooling effect due

to moisture absorption of accumulated dust and dirt, and in-enclosure tempearture rise due to clogged filter.

In the atmosphere where conductive powder floats, dust and dirt will cause such faults as malfunction, deteriorated

insulation and short circuit in a short time.

Since oil mist will cause similar conditions, it is necessary to take adequate measures.

Countermeasures Place in a totally enclosed enclosure.

Take measures if the in-enclosure temperature rises. (Refer to page 10.)

Purge air.

Pump clean air from outside to make the in-enclosure pressure higher than the outside-air pressure.

(4) Corrosive gas, salt damage

If the inverter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or

the relays and switches will result in poor contact.

In such places, take the measures given in Section (3).

(5) Explosive, flammable gases

As the inverter is non-explosion proof, it must be contained in an explosion proof enclosure.

In places where explosion may be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it

structurally complies with the guidelines and has passed the specified tests. This makes the enclosure itself expensive

(including the test charges).

The best way is to avoid installation in such places and install the inverter in a non-hazardous place.

(6) Highland

Use the inverter at the altitude of within 1000m.

If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate

dielectric strength.

(7) Vibration, impactThe vibration resistance of the inverter is up to 5.9m/s2 (2.9m/s2 for the 185K or more) at 10 to 55Hz frequency and

1mm amplitude as specified in JIS C 60068-2-6.

Vibration or impact, if less than the specified value, applied for a long time may make the mechanism loose or cause

poor contact to the connectors.

Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to break.

Countermeasures

Provide the enclosure with rubber vibration isolators.

Strengthen the structure to prevent the enclosure from resonance.

Install the enclosure away from sources of vibration.

1.4.2 Cooling system types for inverter enclosure

From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, lamps,

resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature

lower than the permissible temperatures of the in-enclosure equipment including the inverter.

The cooling systems are classified as follows in terms of the cooling calculation method.

1) Cooling by natural heat dissipation from the enclosure surface (Totally enclosed type)

2) Cooling by heat sink (Aluminum fin, etc.)

3) Cooling by ventilation (Forced ventilation type, pipe ventilation type)4) Cooling by heat exchanger or cooler (Heat pipe, cooler, etc.)

OUTLINE

(2) Clearances around the inverter

To ensure ease of heat dissipation and maintenance, leave at least the shown clearances around the inverter. At least the

following clearances are required under the inverter as a wiring space, and above the inverter as a heat dissipation space.

(3) Inverter mounting orientation

Mount the inverter on a wall as specified. Do not mount it horizontally or any other way.

(4) Above the inverter

Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter

should be heat resistant.

(5) Arrangement of multiple inverters

(6) Placement of ventilation fan and inverter

REMARKS

For replacing the cooling fan of the FR-F740-185K or more, 30cm of space is necessary in front of the inverter.

Refer topage 256for fan replacement.

When multiple inverters are placed in the same

enclosure, generally arrange them horizontally as

shown in the right figure (a). When it is inevitable to

arrange them vertically to minimize space, take such

measures as to provide guides since heat from the

bottom inverters can increase the temperatures in

the top inverters, causing inverter failures.

When mounting multiple inverters, fully take caution

not to make the ambient temperature of the inverter

higher than the permissible value by providing

ventilation and increasing the enclosure size.

Arrangement of multiple inverters

Heat generated in the inverter is blown up from the bottom of

the unit as warm air by the cooling fan. When intalling a

ventilation fan for that heat, determine the place of ventilation

fan installation after fully considering an air flow. (Air passes

through areas of low resistance. Make an airway and airflow

plates to expose the inverter to cool air.)

2.1.2 EMC filter

This inverter is equipped with a built-in EMC filter (capacitive filter) and common mode core.

The EMC filter is effective for reduction of air-propagated noise on the input side of the inverter.

The EMC filter is factory-set to disable (OFF). To enable it, fit the EMC filter ON/OFF connector to the ON position.

The input side common mode core, built-in the 55K or less inverter, is always valid regardless of on/off of the EMC filter

on/off connector.

The FR-F720-0.75K and 1.5K are not provided with the EMC filter ON/OFF connector. (Always ON)

(1) Before removing a front cover, check to make sure that the indication of the inverter operation panel is off, wait for

at least 10 minutes after the power supply has been switched off, and check that there are no residual voltage

using a tester or the like. (For the front cover removal method, refer to page 6.)(2) When disconnecting the connector, push the fixing tab and pull the connector straight without pulling the cable or

forcibly pulling the connector with the tab fixed. When installing the connector, also engage the fixing tab securely.

If it is difficult to disconnect the connector, use a pair of long-nose pliers, etc.

CAUTION Fit the connector to either ON or OFF. Enabling (turning on) the EMC filter increase leakage current. (Refer to page 43)

WARNINGWhile power is on or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock.

CAUTION

The power supply cables must be connected to R/L1, S/L2, T/L3. Never connect the power cable to the U, V, W of the inverter.

Doing so will damage the inverter. (Phase sequence needs not to be matched.)

Connect the motor to U, V, W. At this time, turning on the forward rotation switch (signal) rotates the motor in the

counterclockwise direction when viewed from the motor shaft.

When wiring the inverter main circuit conductor of the 250K or more, tighten a nut from the right side of the conductor. When

wiring two wires, place wires on both sides of the conductor. (Refer to the drawing below.) For wiring, use bolts (nuts) provided

with the inverter.

Handling of the wiring cover(FR-F720-18.5K, 22K, FR-F740-22K, 30K)For the hook of the wiring cover, cut off the necessary

Doing so will damage the inverter.

CAUTION

Do not turn off the control power (terminals R1/L11 and S1/L21) with the main circuit power (R/L1, S/L2, T/L3) on. Doing so maydamage the inverter.

Be sure to use the inverter with the jumpers across terminals R/L1-R1/L11 and S/L2-S1/L21 removed when supplying power fromother sources. The inverter may be damaged if you do not remove the jumper.

The voltage should be the same as that of the main control circuit when the control circuit power is supplied from other than the

primary side of the MC. The power capacity necessary when separate power is supplied from R1/L11 and S1/L21 differs according to the inverter capacity.

When the power supply used with the control circuit is different from the one used with the main circuit, make up a circuit which willswitch off the main circuit power supply terminals R/L1, S/L2, T/L3 when the control circuit power supply terminals R1/L11, S1/L21are switched off.

If the main circuit power is switched off (for 0.1s or more) then on again, the inverter resets and an alarm output will not be held.

WIRING

The input signals are set to sink logic (SINK) when shipped from the factory.

To change the control logic, the jumper connector on the back of the control circuit terminal block must be moved to the

other position.

(The output signals may be used in either the sink or source logic independently of the jumper connector position.)

1)Loosen the two installation screws in both ends of the control circuit terminal block. (These screws cannot be

removed.)

Pull down the terminal block from behind the control circuit terminals.

2)Change the jumper connector set to the sink logic (SINK) on the rear panel of the control circuit terminal block to

source logic (SOURCE).

3)Using care not to bend the pins of the invert er's control circuit connector, reinstall the control circuit terminal block

and fix it with the mounting screws.

CAUTION

1. Make sure that the control circuit connector is fitted correctly.

2. While power is on, never disconnect the control circuit terminal block.

WIRING

(1) Common terminals of the control circuit (SD, 5, SE)

Terminals SD, 5, and SE are all common terminals (0V) for I/O signals and are isolated from each other. Do not

earth(ground) these terminals.

Avoid connecting the terminal SD and 5 and the terminal SE and 5.

Terminal SD is a common terminal for the contact input terminals (STF, STR, STOP, RH, RM, RL, JOG, RT, MRS, RES,

AU, CS) and frequency output signal (FM).

The open collector circuit is isolated from the internal control circuit by photocoupler.

Terminal 5 is a common terminal for frequency setting signal (terminal 2, 1 or 4) and analog output terminal AM.

It should be protected from external noise using a shielded or twisted cable.

Terminal SE is a common terminal for the open collector output terminal (RUN, SU, OL, IPF, FU).

The contact input circuit is isolated from the internal control circuit by photocoupler.

(2) Signal inputs by contactless switches

2.3.4 Wiring instructions

1) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and

power circuits (including the 200V relay sequence circuit).

2) Use two or more parallel micro-signal contacts or twin contacts to

prevent a contact faults when using contact inputs since the

control circuit input signals are micro-currents.

3) Do not apply a voltage to the contact input terminals (e.g. STF) of the control circuit.

4) Always apply a voltage to the alarm output terminals (A, B, C) via a relay coil, lamp, etc.

5) It is recommended to use the cables of 0.75mm2 gauge for connection to the control circuit terminals.

If the cable gauge used is 1.25mm2 or more, the front cover may be lifted when there are many cables running or

the cables are run improperly, resulting in an operation panel contact fault.

6) The maximum wiring length should be 30m (200m for terminal FM).

Terminal screw size: M3.5

Tightening torque: 1.2Nm

The contacted input terminals of the inverter (STF, STR, STOP,

RH, RM, RL, JOG, RT, MRS, RES, AU, CS) can be controlled

using a transistor instead of a contacted switch as shown on the

following basic techniques. Also, since the inverter chops outputs at high carrier frequency, that could generate noises.

If these noises cause peripheral devices to malfunction, measures should be taken to suppress noises. These

techniques differ slightly depending on noise propagation paths.

1)Basic techniques

Do not run the power cables (I/O cables) and signal cables of the inverter in parallel with each other and do notbundle them.

2)Techniques to reduce noises that enter and malfunction the inverter

When devices that generate many noises (which use magnetic contactors, magnetic brakes, many relays, for

example) are installed near the inverter and the inverter may be malfunctioned by noises, the following measures

must be taken:

Provide surge suppressors for devices that generate many noises to suppress noises. Fit data line filters to signal cables.

Earth (Ground) the shields of the detector connection and control signal cables with cable clamp metal.

3)Techniques to reduce noises that are radiated by the inverter to malfunction peripheral devices

Inverter-generated noises are largely classified into those radiated by the cables connected to the inverter and

inverter main circuits (I/O), those electromagnetically and electrostatically induced to the signal cables of the

peripheral devices close to the main circuit power supply, and those transmitted through the power supply cables.

3.1.3 Power supply harmonics

The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power

capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and

transmission path. Take the following countermeasure suppression techniques.

transmission path. Take the following countermeasure suppression techniques.

zThe differences between harmonics and noises are indicated below:

zMeasures

Item Harmonics Noise

FrequencyNormally number 40 to 50 max.

(3kHz or less)High frequency (several 10kHz to 1GHz order)

Environment To-electric channel, power impedance To-space, distance, wiring path

Quantitative understanding Theoretical calculation possible Random occurrence, quantitative grasping difficult

Generated amount Nearly proportional to load capacityDepending on the current fluctuation ratio (larger as

switching is faster)

Affected equipment immunity Specified in standard per equipmentDifferent depending on maker's equipment

specifications

Suppression example Provide reactor. Increase distance.

The harmonic current generated from the inverter

to the input side differs according to various

conditions such as the wiring impedance, whether

a reactor is used or not, and output frequency andoutput current on the load side.

For the output frequency and output current, we

understand that they should be calculated in the

conditions under the rated load at the maximum

operating frequency.

CAUTIONThe power factor improving capacitor and surge suppressor on the inverter output side may be overheated or damaged by the

high frequency components of the inverter output. Also, since an excessive current flows in the inverter to activate overcurrent

protection, do not provide a capacitor and surge suppressor on the inverter output side when the motor is driven by the inverter.

For power factor improvement, install a reactor on the inverter input side or in the DC circuit.

1Reactor installation

(FR-HAL, FR-HEL)

Install an AC reactor (FR-HAL) on the AC side of the inverter or a DC reactor (FR-HEL) on

its DC side or both to suppress outgoing harmonic currents.

2High power factor converter

(FR-HC, MT-HC)

The converter circuit is switched on-off to convert an input current waveform into a sine

wave, suppressing harmonic currents substantially. The high power factor converter (FR-

HC, MT-HC) is used with the standard accessory.

3Installation of power factor

improving capacitor

When used with a series reactor, the power factor improving capacitor has an effect of

absorbing harmonic currents.

4Transformer multi-phase

operationUse two transformers with a phase angle difference of 30 as in - , - combination

to provide an effect corresponding to 12 pulses, reducing low-degree harmonic currents.

5Passive filter

(AC filter)

A capacitor and a reactor are used together to reduce impedances at specific frequencies,

producing a great effect of absorbing harmonic currents.

6 Active filter

This filter detects the current of a circuit generating a harmonic current and generates a

harmonic current equivalent to a difference between that current and a fundamental wave

current to suppress a harmonic current at a detection point, providing a great effect of

absorbing harmonic currents.

Inverter-driven 400V class motor

3.4 Inverter-driven 400V class motor

In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals.

Especially for a 400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is

driven by the inverter, consider the following measures:

PRECAU

TIONSFORUSEOFTHEINVERTER

zMeasuresIt is recommended to take either of the following measures:

(1) Rectifying the motor insulation and limiting the PWM carrier frequency according to the wiring length

For the 400V class motor, use an insulation-enhanced motor.

Specifically,

1)Specify the "400V class inverter-driven insulation-enhanced motor".

2)For the dedicated motor such as the constant-torque motor and low-vibration motor, use the "inverter-driven,

dedicated motor".

3)SetPr. 72 PWM frequency selection as indicated below according to the wiring length

(2) Suppressing the surge voltage on the inverter side

Connect the surge voltage suppression filter (FR-ASF-H) to the 55K or less and the sine wave filter (MT-BSL/BSC)to the 75K or more on the inverter output side.

Wiring Length

50m or less 50m to 100m exceeding 100m

Pr. 72 PWM frequency selection 15(14.5kHz) or less 9(9kHz) or less 4(4kHz) or less

CAUTION

For details ofPr. 72 PWM frequency selection , refer to page 142. (When using an optional sine wave filter (MT-BSL/BSC) for the or

more, set 25 inPr.72 (2.5kHz).)

For explanation of surge voltage suppression filter (FR-ASF-H) and sine wave filter (MT-BSL/BSC), refer to the manual of each

option.

Precautions for use of the inverter

(13) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in theinverter's input side and also make up a sequence which will not switch on the start signal.If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as thepower is restored.

PRECAU

TIONSFORUSEOFTHE

INVERTER

When performing an operation of frequent start/stop of the inverter, increase/decrease in the temperature of thetransistor element of the inverter may repeat due to a continuous flow of large current, shortening the life from thermalfatigue. Since thermal fatigue is related to the amount of current, the life can be increased by reducing bound current,starting current, etc. Decreasing current may increase the life. However, decreasing current will result in insufficient

torque and the inverter may not start. Therefore, increase the inverter capacity to have enough allowance for current.

(15) Make sure that the specifications and rating match the system requirements.
