Re: G0752 CNC conversion keeps popping breakers
I don't have a real handle on what you have but here are my thoughts. A frequency drive has every kind of protection you can think off built into it so it's real rare that a drive will actually trip a breaker unless the drive has totally smoked itself. You indicate this drive is powered through a GFI and I'll bet that is the culprit. Those devices by nature are very sensitive to ground faults or minor over current conditions. If you feel you have the drive connected properly then I would plug or wire it into a source other than a GFI. A common 15 or 20 amp DCO would be perfect..a standard wall outlet.
Give that a try and I'll bet it does the trick. The drive will protect itself and if it's really toast it will produce a code, typically not trip a breaker.
