- Servo amplifiers can cause trouble, so here's how you can quickly trouble shoot them. If you need CNC parts or tools check out my store.

Done that in the field tons of times. One time though the customer had a short in their 4ax cable and it bbq'd the other amp. Customer got two amps that day, one on their dime and one on ours. Live and learn!
Yes, probably should have made a bigger point about that. Amplifier short circuit- obviously don’t swap that one and check it but phasing alarms random overcurrent things like that. I think, if anything, I’m too general in my videos.
Just found your channel and subscribed. Awesome just what I've been looking for.🙏
Welcome aboard!
thanks for the videos.
My pleasure!
At what point would you check for shorted motor or cable with multimeter or megohmmeter?
Concern would be if we had a short that fried the drive, we could fry the second.
If you are lacking over current protections you have far bigger issues. Regardless you can check for resistance... now what does the number mean? See where I'm going?
@@ShainAndrews The drive IS the overcurrent protection. Often when a drive fails it's because a motor is full of coolant in it or a power cable worn thru and shorted. Advanced drives do a ground fault check BEFORE energizing but more basic drives do not. A dead short can take them out in short order. A megohm meter can check for breaks in inulation in cables and motor windings a regular ohmmeter cannot, and a miliohm meter is a very precise ohm meter you can check to make sure you windings are all balanced, check for opens or a short within the windings.
See Callixtus14's post below about smoking an amp due to a short.
I’d say it depends on the alarms. Did the main breaker trip or was it just a simple alarm. Most of the time the amps fail on the control circuitry
