Delta MS300 inverter is a new type of inverter launched to replace old inverters such as VFD-M, VFD-L. It also has a built-in RS485 communication port for Modbus-RTU Control.
Today plc247.com will guide you to use HMI Proface GP4402WW to control and monitor Delta MS300 VFD through Modbus RTU Communication Standard.
Delta MS300 & GP4402WW “Wiring Diagram”
Delta MS300 Modbus RTU Configuration
In addition to the basic parameters of the inverter (Frequency, voltage, current, Acc/Dec,…) then we need to set the communication parameters as follows
+ P00.20 = 1 (Modbus-RTU Control Frequency)
+ P00.21 = 2 (Modbus-RTU Control Motor)
+ P09.00 = 1 (Address Slave = 1)
+ P09.01 = 9.6 (9600bps)
+ P09.02 = 0
+ P09.03 = 1.0 (Time Detect Err = 1.0s)
+ P09.04 = 14 (Modbus-RTU Slection 8bit / stop bit = 1/ Even)
Registers Address Table
Note: GP4402WW HMI Address = “400001 (dec) + Device Address”
+ Control Address = 400001(dec) + 2000(hex) = 400001 + 8192 = 408193
- Set Word 408193 = 18 >>> Forward Run
= 34 >>> Reverse Run
= 1 >>> Stop
+ Frequency Set Address = 400001(dec) + 2001(hex) = 400001 + 8194 = 408194
+ Frequency Output Address = 400001(dec) + 2103(hex) = 400001 + 8451 = 408452
+ Current Output Address = 400001(dec) + 2104(hex) = 400001 + 8452 = 408453
+ Voltage Output Address = 400001(dec) + 2106(hex) = 400001 + 8454 = 408455
