I would say exactly the opposite. Increase P until the oscilation is faster/shorter.

Everything looks good, except that when I JOG motor, it turns as a "pendulum". I meant that it passes point where it should stop, than shaft turns back direction and again passes "center" point. That repeats 3 to 4 times until shaft of the motor rest on the target position. I believe that need reduce P and increase D. I found some book about tune up of servo motors and their I found "symptom" of problem with the tune up of AC servomotors. I am interesting in find out which parameter causes trouble? Also, my amplifier SD-94 (servo dynamics), can work in current, velocity and position regime. Which one will be better for EMC2? I tried velocity and position regime Thank you, AramK -------------------------------------------------------------------------------- > ------------------------------------------------------------------------- > Take Surveys.
