Communication between PLC and Delta VFD-EL Series AC Motor Drive (MODRD/MODWR)

Communication between PLC and Delta VFD-EL Series AC Motor Drive (MODRD/MODWR)

Control Purpose:

• Repeatedly reading the master frequency and output frequency of VFD then store them in D0 and D1 by MODRD instruction.

• Repeatedly setting the running frequency by MODWR instruction. For example, setting the AC motor drive to run forward in 40Hz.

Parameter Settings for VFD-M Series AC Motor Drive:

Parameter Set value Explanation

02.00 03 Master frequency determined by RS485 com port.

02.01 03 Operation determined by RS-485 com port, keypad STOP is effective.

09.00 02 Communication address: 02

09.01 01 Communication rate: 9600

09.04 03 8,N,2 (Modbus, RTU)

Communication between PLC and Delta VFD-EL Series AC Motor Drive (MODRD/MODWR)

1- Create function block as follows to specify the protocol & COM2 parameters:
