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)
