Mitsubishi E700 Series inverter is one of the most commonly used inverters on the market, it supports all basic types of inverter control including Modbus-RTU protocol.
Today plc247.com will guide you to use the Samkoon HMI (Model SK-070HS) to control the Mitsubishi FR-E720 inverter via Modbus-RTU, both of which have a built-in RS485 Communication Port.
Samkoon HMI & Mitsubishi FR-E720 “Wiring Diagram”
+ Below is the wiring diagram between HMI Kinco SK-070HS and Mitsubishi FR-E720 VFD.
Note: Use a 120Ω terminal resistor if the communication distance is long
Mitsubishi FR-E720 Modbus Parameters Setting
To be able to control the inverter via Modbus-RTU protocol, we need to set the following communication parameters:
+ Pr117: 1 (Slave Address)
+ Pr118: 96 (Baudrate 9600)
+ Pr119: 0 (8bit, stop bit = 1)
+ Pr120: 2 (Even)
+ Pr121: 9999
+ Pr122: 9999
+ Pr123: 9999
+ Pr124: 1
+ Pr340: 1
+ Pr549: 1
+ Pr79: 2 (Last Setting)
Mitsubishi FR-E720 Modbus Register Address
Note: Proface HMI – Mitsubishi FR E700 VFD
HMI Address Using = VFD Address – 40001
>>> Motor Control Address = 40009 – 40001 = 8
- Set Word “8” = 2 >>> Forward Run
- Set Word “8” = 4 >>> Reverse Run
- Set Word “8” = 0 >>> Stop
>> Frequency Setting Address = 40014 – 40001 = 13
+ Output Frequency Address = 40201 – 40001 = 200
+ Output Current Address = 40202 – 40001 = 201
+ Output Voltage Address = 40203 – 40001 = 202
