Danfoss Micro Drive FC-51 inverter is the most popular inverter series that Danfoss has ever produced to serve small load AC motors from 0.18 to 22 kW. The Danfoss Micro Drive FC-51 inverter of the VLT® family enjoys comprehensive quality in design, reliability and user-friendliness.
Today plc247.com will guide you to control Danfoss FC51 via Modbus-RTU protocol with HMI Mitsubishi GT2505-VTBD in the easiest way possible.

Danfoss FC51 “Modbus RTU” Parameters Setting
Below are the communication parameters that we need to set up for Danfoss FC51 to be able to control it with Modbus-RTU communication.
Registers Address
Note: Mitsubishi GOT2000 Holding Registers Address =
“VFD Address (Dec) + 400001“
+ Control Word Address = 49999 + 400001 = 450000 (dec)
- Set Word 450000 = 1148 (dec) >>> Run Forward
= 33916 (dec) >>> Run Reverse
= 1084 (dec) >>> Stop
= 1212 (dec) >>> VFD Reset
+ Set Frequency Address = 50009 + 400001 = 450010 (dec)
>>> Reference Setting = 0 to 16384(dec) ~ (0 to 100%)
+ Output Frequency Address = 416130 (dec)
