PLC OMRON CP1H and Mitsubishi inverter FR-E700 Series are both common automation devices in factory factories.
With the problem of remote inverter control or controlling multiple inverters with 1 PLC, we can use Modbus-RTU RS485 (supports up to 32 stations and distances up to 1200m)
Today I will guide you to use PLC CP1H (CP1L, CP1E) to control Mitsubishi FR-E720 inverter by CP1W-CIF11 Module
Connection diagram PLC OMRON CP1H & VFD Mitsubishi FR-E720
VFD settings FR-E720
Below are the required parameters of the Mitsubishi FR-E720 Inverter
For this project, please install according to the parameters below
- Pr117 : “1” (Slave.1)
- Pr118 : “9600” (Baud rate)
- Pr119 : “0” (8bit/Stop bit.1)
- Pr120 : “2” (Even bit)
- Pr121 : “9999”
- Pr122 : “9999”
- Pr123 : “9999”
- Pr124 : “1”
- Pr340 : “1”
- Pr549 : “1”
- Pr79 : “6” ( External Mode > Last setting )

Saludos caballero
excelente explicacion
Tengo un cj2m-cpu 32 y 7 mitsubshi dr-d40, copie su programa y lo unico que no me funciona es A640.00 PUES LA CPU DE ESTE MODELO NO CUENTA CON ESTE BIT. Sin embargo tengo en la misma instalacion un cm1l y funciona genial. si puede ayudarme se lo agradeceria.
sir please comment via english
Greetings, gentleman, excellent explanation. I have a cj2m-cpu 32 and 7 mitsubshi dr-d40, I copied your program and the only thing that does not work for me is A640.00 BECAUSE THE CPU OF THIS MODEL DOES NOT HAVE THIS BIT. However, I have a cm1l in the same installation and it works great. If you can help me I would appreciate it.
