Today thelivingchristmascompany.com will continue to guide you to use LabVIEW software on PC to control Danfoss FC302 VFD (we need to prepare “USB to RS485” cable)

Danfoss FC302 & Computer “Wiring Diagram”

Danfoss FC302 Modbus-RTU Setting

In order for us to be able to control Danfoss FC302 with Modbus RTU, we need to set the communication parameters as shown in the table below

FC302 Registers Address for Control

>>> VFD Control Command = 49999

+ Set Word 49999 = 1148 (dec) >>> Run Forward
= 33916 (dec) >>> Run Reverse
+ Set Word 49999 = 1084 (dec) >>> Stop
+ Set Word 49999 = 1212 (dec) >>> VFD Reset

>>> Speed Reference Address = 50009
+ Speed Reference = 0 to 16384(dec) ~ (0 to 100%)

FC302 Registers Address for Data Monitoring

Note: Danfoss FC302 Address = “(Table Address*10) – 1“

• Voltage Output Address = 16119

• Frequency Output Address = 16129

• Current Output Address = 16139

• Speed Output Address = 16169
