  If your Eurotherm Drives Servo Drive motor runs unevenly, check the setpoint wiring, grounding, and shielding. Also, high P-amplification in the speed controller may be the cause; if so, reduce the value using EASYRIDER setting/speed controller or PROG-key. Another possible cause is a too-small I-time in the speed controller; reduce its value using EASYRIDER setting/speed controller or PROG-key.
