My AC servo minas A6 is shaking too much

I am using a AC servo minas A6 (MSMF082L1U2) with drive MCDLT35SF. When testing with dynamic load, servo running unstable (too much vibration and oscillation). Everything is running usual when i test without load or load under 100 grams.
Anyone can help me with this (reasons and how to fix it). Thanks.

Try increasing the D value in the PID settings

Go through your manual

Set the parameters for machine rigidity / stiffness then auto Tune this will get you close then you can adjust 1st Gain Loop 2Gain Loop Etc

Your problem right now is your Gains are set to high

And where would he find a D value in his servo drives

Is there no way to adjust the PID in that drive?

You should understand the servo drive that the question was being asked about most modern servo drives are setup completely different I have not looked but I don't think you will fined the word PID in the manual
