I have two problems - firstly tuning a MR-J3-70B on a belt system
I get smooth movement with no overshoot - but the movement has a huge droop
Remove the Droop using 100% Velocity Feed forward and I get overshoot (Accel /Decel time target is 200 ms from 5000 rpm)
I have looked at the vibration filters and have not have much success
How do I remove the droop yet still have no overshoot? Any pointers - what parameters to look at
Been bashing my head on this for a couple of days

Secondly A MR-MQ100 that has to follow a synchronous encoder reference closely
What are the parameters to look at - does anyone have a mechanical program that does encoder speed dependent phase advance?
