yeah with r39 there is always confusion as it has no reference.

What I think is that it is communicated in the unit [Ws]. But I also cannot give a clear answer on how to handle r39 to be honest. 

Yeah, I posted all screenshots in the other post:

I tried that, but actually if you think about it one of the problems (if not the real problem) is that I receive a fixed value. Either being REAL or DINT, its stuck with 7FFF. It does never change but I have the motor running and it should be constantly updating.

And I know I havent reached maximum because I can see it incrementing (constantly) while looking at the online value in the DRIVE.

Hi Jorge, I have same problem. Can you share with me solution for this problem. Thanh you so much!!
