I got an answer from Danfoss: Modbus TCP on Danfoss VFDs does not support coil addressing.
I had the same expirence with their engg , actually they dont know most of the functionalities , we still get stupid answers from them.I have set all the parameters as per manual for Modbus operation at 9600bps 8n1.
I am unable to start the drive I am sending the following frame to start the drive:
Address of Drive 2
Can someone help me, Danfoss service Engineer has refused to help since I have not purchased the drive from their Official System House...
