The Mitsubishi FR-E700 Series inverter is a low-cost but high-quality Mitsubishi inverter, although it has been around for a long time, it is still popularly used in factories around the world.
We can control the FR E720 inverter in many different ways such as button control, rheostat, switch, CC -Link, today plc247.com will guide you to control with HMI Weintek MT8081iE via communication MODBUS-RTU

Parameters of Mitsubishi Inverter FR-E700 Series
Parameters Setting for Modbus-RTU
In this project I use the following parameters:
- 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 )
======
Address where holding register data write will be started Starting address = Starting register address (decimal)-40001
For example, setting of the starting address 0001 reads the data of the holding register 40002
