Hello everyone. PLC Delta SVP-Series is a type of PLC originating from Taiwan, it is very cheap and has high quality, programming like Mitsubishi or Siemens PLC optionally, so it is extremely popular in many applications. small machines.
Today plc247.com will start a series of articles to guide you to use PLC Delta DVP-14SS2 to control inverters and thermostats via Modbus-RTU. And today I use it to control Mitsubishi FR-E720 Inverter.

In addition to the motor settings such as frequency, current, and voltage, we set the communication parameters as follows:
+ Pr117 (Slave Address) = 1
+ Pr118 (Baudrate) = 3 (9600bps)
+ 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)
Register Control Address
With inverter FR-E700 Series
Starting address = Starting register address (decimal)-40001
>>> 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 >>> Motor Stop
>>> Set Frequency Address =40014 – 40001 = 13 (dec) = D (hex)
Register Monitoring Address
+ Output Frequency = 40201 – 40001 = 200 (dec) = C8 (hex)
+ Output Current = C9 (hex)
+ Output Voltage =CA (hex)
