Proface HMI “Modbus RTU” Danfoss FC51 Tutorial

FC51 inverter with special design for close installation to save maximum space. The outstanding typical features of Danfoss inverters are still maintained. Compact design The VLT® Micro is 40% more compact than its class of inverters.

Today plc247.com will guide you to use HMI Proface to directly control Danfoss FC51 inverter by Mobdus communication through RS485 port integrated on FC51.

Danfoss FC51 Modbus Parameters Settings

In addition to the basic parameters of the inverter (frequency, voltage, current…) we need to install the following communication parameters

Control Registers Address

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

>>> Motor Control Address = 400001 + 49999 = 450000

• Set Word 450000 = 47C (hex) or 1148 (dec) >>> Forward Run
  = 847C (hex) or 33916 (dec) >>> Reverse Run
  = 43C (hex) or 1084 (dec) >>> Stop
  = 4BC (hex) or 1212 (dec) >>> VFD Reset

>>> Frequency Setting Address = 400001 + 50009 = 450010
>>> Reference Set = 0 to 16384(dec) ~ (0 to 100%)
