Hello everyone!
Danfoss FC302 is one of the most modern multi-function inverters in the world. It meets the most demanding inverter requirements. It is also a universal inverter that supports most communication connections.
Today plc247.com will guide you to use HMI Proface GP4402 to control Danfoss FC302 inverter via Modbus RTU (both have built-in RS485 port)

Danfoss FC302 Modbus RTU Configuration
In order for the inverter to be controlled by Modbus RTU we need to configure the following communication parameters
Danfoss FC302 Registers Address for Control
Note: GP4402WW HMI Address = “400001 (dec) + Device Address”
+ Control Word Address = 400001 + 49999 = 450000
>>> Set Word 450000 = 47C (hex) or 1148 (dec) >>> Run Forward
= 847C (hex) or 33916 (dec) >>> Run Reverse
= 43C (hex) or 1084 (dec) >>> Stop
= 4BC (hex) or 1212 (dec) >>> Reset
+ Frequency Reference Address = 400001 + 50009 = 450010
>>> Reference Set = 0 to 16384(dec) ~ (0 to 100%)
Danfoss FC302 Registers Address for Monitoring
+ Frequency Output Address = 400001 + 16129 = 416130
+ Speed Output Address = 400001 + 16169 = 416170
Proface GP4402WW Modbus RTU Setting
We need to set the same communication parameters as those installed by Danfoss FC302, In addition, we need to install and use 32bit data reading in the high word first:
