Omron CP1H “Modbus RTU” Inovance MD200 Tutorial

Written by

Hello friends!
In the previous article, showed you how to use PLC Mitsubishi FX3U to control Inovance MD200 inverter through Modbus RTU, today will continue to guide you to use Omron PLC to control it.

The PLC model I use is the Omron CP1H PLC combined with the CP1W-CIF12 Module (or CP1W-CIF11) to connect to the built-in RS485 port in the Inovance MD200 inverter.

PLC Omron & Inovance MD200 “Connection Diagram”

Below is the RS485 communication connection diagram between CP1W-CIF11/12 and Inovance MD200.

Inovance MD200 Inverter Parameters Setting

In addition to the basic parameters of the inverter installed according to the motor (frequency, voltage, current…, we need to install additional communication parameters for the Inovance MD200 inverter.

Inovance MD200 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 Max Frequency)

+ Output Frequency Address = 1001 (hexa)
Output Voltage Address = 1003 (hexa)
Output Current Address = 1004 (hexa)

PLC Omron “Modbus RTU” Configuration

In order for the Omron PLC to control and monitor the Inovance MD200 inverter, we need to set them the same communication parameters.
