Inovance MD200 Modbus Configuration

In order for the Mitsubishi FX5U PLC to control the Inovance inverter using the Modbus RTU protocol, we need to set the following communication parameters:

+ VFD Control Address = 2000 (hex)

  • Set Word “2000” = 1 >>> Forward Run
  • Set Word “2000” = 2 >>> Reverse Run
  • Set Word “2000” = 6 >>> Stop

+ Set Frequency Address = 1000 (hex)
>>> Frequency Reference = (0 to 10000 dec) ~ (0 to VFD Max Frequency)

  • Output Frequency Address = 1001 (hex)
    Output Voltage Address = 1003 (hex)
    Output Current Address = 1004 (hex)

How have we set up the communication parameters for the inverter, the settings for the Mitsubishi FX5U PLC are exactly the same.
