Krow,
You need to find the power supply that feeds the control PCB's. You should be looking for DC voltages such as 5, 12, -12, and 24 volts or what ever the Fanuc 11M uses to power the digital and analog components on it's PCB's. The volateg that you measured sounds like the input voltage. Not sure if Fanuc has test points on it's power supply for testing the voltages or not. You may need to get a rent a tech in whose familiar with the 11M to figure out your problem.
Good Luck,
Chippy |
