Hi. In the previous article, plc247.com showed you how to use PLC Delta to control many inverters of different brands. Today I will continue to guide you to use DVP-14SS2 PLC to control DELTA VFD-M Inverter.
Delta VFD-M inverter is a type of inverter used extremely commonly in factories because of its competitive price but extremely good quality, along with RS485 communication support built into the RJ11 port.

You are looking to buy Jack RJ-11 (phone jack) to connect the VFD-M inverter.
VFD-M Parameters Setting
In order for VFD-M to be controlled by Modbus-RTU, we need to set the following communication parameters (I choose data type 9600/8/E/1)
+ Pr00: 03 (Control Frequency via RS485)
+ Pr01: 04 (Control Motor via RS485)
+ Pr88: 01 (Slave Address)
+ Pr89: 01 (9600bps)
+ Pr92: 04 (8bit/1bit/Even)
+ Pr157: 01 (Modbus-RTU)
Register For Control Motor
+ Motor Control Address = 2000 (Hex)
- Set 2000 (Hex) = 0000.0000.0001.0010 (Bin) = 18 (dec) >>> Forward Run
- Set 2000 (Hex) = 0000.0000.0010.0010 (Bin) = 34 (dec) >>> Reverse Run
- Set 2000 (Hex) = 0000.0000.0000.0001 (Bin) = 1 (dec) >>> Stop
+ Setting Frequency Address = 2001 (Hex)
Register For Data Monitoring
+ Output Frequency Address = 2103 (Hex)
+ Output Current Address = 2104 (Hex)
+ DC-BUS Voltage Address = 2105 (Hex)
+ Output Voltage Address = 2106 (Hex)
