Troubleshoot Servo Errors When Attempting to Jog (G4 CNC)

If this happened the first time you try to jog, the problem is most likely just a tripped circuit breaker. Try pushing in the circuit breaker button on the back of the control, just above the motor connectors, then turn servos on and try to jog.

If you still get the error when you try to jog, the servo amplifier may have faulted. Ppress Esc to reset the error, and turn the servos back on. Take the blue cover off the control, and look at the top of the servo amps. Normal condition with servos on is green LED lit; flashing red LED indicates a fault. If one of the LEDs is flashing red, set control off, and wait for the LEDs on both amps to go out; power up, set servos on and try to jog.

If one of the LEDs is flashing red, set control off, and wait for the LEDs on both amps to go out. Wait a few seconds to be sure amp has reset, then set control power on, set servos on and try to jog.

If you don't get green lights, or if you do get green lights but still can't jog the machine, further troubleshooting is necessary.
