I have a Fanuc Powermate D getting Alarm 414 (Digital Servo System is Abnormal).
Diagnostic #0200:
X: 0 1 0 1 0 0 0 0
U: 0 1 0 0 0 0 0 0
According to the manual, the diagnostics above tell me that the X & U axis have low voltage.
The servo for the X & U axis (A06B-6066-H233) is displaying "2" on the LED alarm display. This would mean that I have an LV5V Control Power Low Alarm. +5 of control power is abnormally low.
We measured about 4.8ish volts. Do you think this is too low? I would think anything over 4.75V would be fine.
Does anyone got any ideas for us? How do we adjust the voltage to get exactly 5.0V? Is the servo amplifier faulty?
