look for Load Inertia paramenter LDNIT and try to decrease the value
Check for worn ball screw or bearings, backlash can cause servo motor to hunt or vibrate.

Backlash is term used to describe excessive clearances caused by worn bearings or ball screws and nuts. When the backlash becomes too great it can cause the servo to vibrate and shake. You can easily feel this by turning it by hand. Also you said the motor had heated up, check to see if the windings have not shorted.
