Higher position loop gain value improves the responsiveness of the servo driver and lessens the
positioning time.
Position loop gain value shouldn’t exceed responsiveness of the mechanical system and take in
consideration velocity loop gain, if not it might cause vibration, mechanical noise and overtravel.
As velocity loop gain is based on position loop gain, please set both values accordingly.
