Current Micro830 Motion Support - Modbus

• Modbus communications to one or more Kinetix 3 servo drives

– Micro830 user application uses MSG_MODBUS instructions or K3-specific UDFBs

(a ailable from Sample Code ebsite) to control ser o dri es in inde ing mode(available from Sample Code website) to control servo drives in indexing mode.

– Refer to Kinetix 3 Host Commands for Serial Communication manual for Modbus

commands and parameters.

• Micro830 controller requires serial port plug-in configured as Modbus

Available K3 UDFBs from Sample Code Website

• RA_K3_MBUS_OperationMode – Reads the operation mode of the drive and change it if the

input is different. This function block continuously updates the output values on a 10 second

cycle, but will only write the new mode to the drive when triggered. y y gg

• RA_K3_MBUS_IndexControl – Provides simple index control and status for the drive. The

default operation runs continuously with a 100 millisecond cycle time.

• RA_K3_MBUS_WriteIndex – Provides simple index configuration for one index at a time in _ _ _ p g

the drive. This function block operates on a trigger, but will take more than one scan to complete.

• RA_K3_MBUS_ReadIndex – Reads the current index configuration for one index at a time in

the drive. This function block operates on a trigger, but will take more than one scan to complete.

• RA_K3_MBUS_VelocityControl – Provides simple velocity control and status for the drive.

The default operation runs continuously with a 100 millisecond cycle time.

• RA_K3_MBUS_ChangeVelocity – Updates the Preset Velocity values for the drive. This

function block continuously updates the output values on a 10 second cycle, but will only write the

input values to the drive when triggered.

• RA_K3_MBUS_Jog – Assuming that the drive is ready but not enabled, this function block will

ll th t j th d i f d d b k d t th d f lt j d ith t h iallow the user to jog the drive forward and backward at the default jog speed, without changing

the operation mode of the drive.

Conveyor application example for the lab

Now let’s take a look at a simple program for a conveyor application for

loading freight. A motor drives the conveyor belt moves the item(s) until

the item can be unloaded Depending on the type of freight the speed ofthe item can be unloaded. Depending on the type of freight, the speed of

the conveyor is adjusted

What controls do I need for this application?

• A motor

• A drive controller for the motor

• A small PLC to coordinate the start/stop/speed change of the conveyor

• An HMI – may be a simple switch(es) or touchscreen display.
