What does bad servo pre-amp mean?

Here's what I know... A pre-amplifier (or preamp) as relating to ay servo system is simply an electronic amplifier that prepares a smaller electrical signal for more amplification through a series of components. Basically, it is designed to boost the signal strength so it is stable enough to survive further amplification suitable for driving a motor.

As for a bad servo pre-amp, I would think it is a failure that would require circuit board replacement at the very least, or complete drive replacement in most cases. I can't say I've seen this too often. A bad motor pre-amp could also give a generic drive fault requiring drive repair or replacement depending on the manufacturer.

If you have a servo pre-amp fault or alarm, you may just want to swap drives and take it from there.

Hope that helps...
