![Page 18: VFD-EL WITH PLC 12SE](https://reader031.fdocuments.us/reader031/viewer/2022020623/61f271519435377b301a2873/html5/thumbnails/18.jpg)
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)
