G120 control via s7-1200

1/30/2022 5:14 PM	Rate (0)
Hanek Posts: 4 Rating: (0)	Hello, I would like to write a program using Motion Control for a s7-1200 controller connected to a G120 drive via profinet interface. I know from previous topics that this can be done without a physical encoder, but I don't know how to do it. How to create a virtual encoder? I would very much appreciate your help.

Hanek Posts: 4 Rating: (0)	Thank you very much for your help. I will ask just to be sure. Trying to implement this problem through Motion Control blocks doesn't make much sense? I have been struggling with this problem for a week now. I have spent many hours of work on it and have not been able to solve it.
