Hello everyone! In the previous post, plc247.com showed you how to use some HMIs to control Inovance MD200 inverters via Modbus RTU (RS485).
Today I will continue to guide you to use PLC Mitsubishi FX3U to control Inovance MD200 using Modbus RTU protocol.

Inovance MD200 Modbus Parameters Settings
Below are the communication parameters that need to be set up for the Inovance MD200 so that we can control it with Modbus-RTU.
Inovance MD200 Modbus Registers Address
>>> VFD Control Address = 2000 (hexa)
- Set Word “2000” = 1 >>> Forward Run
- Set Word “2000” = 2 >>> Reverse Run
- Set Word “2000” = 6 >>> Stop
>>> Set Frequency Address = 1000 (hexa)
Frequency Reference = (0 to 10000 dec) ~ (0 to VFD Max Frequency)
- Output Frequency Address = 1001 (hexa)
Output Voltage Address = 1003 (hexa)
Output Current Address = 1004 (hexa)
