HMI Proface “Modbus RTU” Delta VFD-M

Written by plc247.com

Delta VFD-M is a type of inverter commonly used in small and medium-sized machines, now it is no longer produced and replaced by newer Models. However in many cases we still have to work with them.

Today plc247.com will guide you to use HMI Proface GP4402WW to connect to Delta VFD M via built-in RS485 “Modbus RTU”

GP4402WW & Delta VFD-M “Connection Diagram”

Delta VFD-M Communication Setting

Note: GP4402WW HMI Address = “400001 (dec) + Device Address”
Register for Control

>>> Motor Control Address = 400001 (dec) + 2000 (hex)
= 400001 (dec) + 8192 (dec) = 408193

+ Set Word 408193 = 18 >>> Forward Run
= 34 >>> Reverse Run
= 1 >>> Stop

>>> Frequency Reference Address = 400001 (dec) + 2001 (hex)
= 400001 (dec) + 8193 (hex) = 408194

Register for Monitoring

>>> Output Frequency Address = 400001 (dec) + 2103 (hex)
= 400001 (dec) + 8451 (dec) = 408452

>>> Output Current Address = 408453

>>> Output Voltage Address = 408454
