I'm working on a lathe which has suddenly decided to trip the main breaker instantly on startup when I press "MachineReady" button on panel. None of the internal circit breakers are tripped, however there is a smell in the control cabinet as well as a slight haze inside as well. I have been unsucessful in tracking down the source of the smoke and my documentation on the machine appears incomplete.
Obviously something very energetic is happening and I am wondering if there is a way to check the spindle motor amp without removing it and pulling it apart, It's my #1 suspect at this point.
The lathe was working fine on friday, this problem cropped up during startup this morning.
If anyone has a troubleshooting guide they could look at, maybe post a flowchart, I would be very grateful.
Serial # P8HC0173, has Fanuc 16-T control.
