I am not familiar with Yaskawa VFD.... Check proper Modbus wiring and enable specific Modbus function in VFD, also PLC & VFD configuration settings should match correctly. Atlast transfer the program & cycle the power after proper settings.

CP1L PLC data mapping is different then CP1E, Change the DM addresses if you mentioned the same as CP1E

I have mentioned the same as for CP1L all is fine but in cp1l there is a feature of serial gateway. where the packet is converted by this gateway at the end either in Compoway(Omron Protocol) or Modbus. how can we enable this serial gateway because i am getting an error 0x04 which is because of disable of this serial gateway
