Is it still happening, or did you already solve it?

1. Is it reset-able (without power down)? 2. Is this a CP41 or CP42 (only 1 D motor)? 3. Any pattern, or just random? 4. How often, once a PCB, once a hour, etc?

Do you have an extra VME Servo Board to try? Servo Overflows are not as common as Over Currents or hard amplifier failures. They seem to be resolved by replacing the servo board and not the amp or motor.

My $.02

Just for starters you are experiencing a possible closedloop feedback error

1 your motor is on its way out

2 increase the reach pulse in propers

3 check gain of servo

mail me for more info
