Hello everyone!
Delta HMI DOP-107EV and Mitsubishi FR-E700 Inverter are two extremely popular devices in the world. Cheap price, good quality, high durability are the advantages that these two devices bring, along with that they also have built-in RS485 port to support Modbus-RTU Communication.
Today plc247.com will guide you to use Delta HMI to connect control and monitor Mitsubishi FR-E720 inverter through Modbus-RTU communication standard. These are quick connections, easy drive control and monitoring as well as extremely long control distances.
DOP-107EV & Mitsubishi FR-E700 “Wiring Diagram”
+ Below is the connection diagram between HMI and VFD
Mitsubishi FR-E700 Modbus Parameters Setting
In order for Delta HMI to control Mitsubishi FR-E700 Series, we need to install the following communication parameters for the inverter
+ Pr117: 1 (Slave Address)
+ Pr118: 3 (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 (Final settings)
Mitsubishi FR E720 Modbus Registers Address
Note: VFD Address = Starting register address (decimal) – 40001
+ Motor Control Address = 40009 – 40001 = 8 (Dec) = 8 (Hex)
- Set Word 8 (Hex) = 0000 0000 0000 0010 = 2 >>> Forward Run
- Set Word 8 (Hex) = 0000 0000 0000 0100 = 4 >>> Reverse Run
- Set Word 8 (Hex) = 0000 0000 0000 0000 = 0 >>> Stop
+ Frequency Setting Address = 40014 – 40001 = 13 (Dec) = D (Hex)
+ Frequency Output Address = 40201 – 40001 = 200 (dec) = C8 (hex)
+ Current Output Address = C9 (hex)
+ Voltage Output Address =CA (hex)
Delta DOP-107EV Modbus-RTU Configuration
We need to set the communication parameters of Delta DOP-107EV exactly the same as those installed for Mitsubishi FR-E720 Inverter
