Post subject:  Feedforwards


I am working with Lenze I700 drives in sync position mode. Codesys sends the speed feedforward in encoderPulses/s and i700 interprets it as rpm factorized in 480000/2^32. That causes an following error proportional at speed. There exist any parameter to solve that?

Modifying fFactorvel in ref_axe it works (But not seems to be a elegant method :( ), but I cannot know how to set the addTorque FF.
