Assumed cause
The voltage between the positive
and negative terminals in the
control power supply converter
exceeded the specified value.
The voltage was suddenly
increased by the phase advance
capacitor or the uninterruptible
power supply (UPS).
Cause and
The Regeneration Resistor wiring
correction
is broken.
The External Regeneration
Resistor is not suitable.
The Servo Drive failed.
Attached None
information
Precautions/ "12" is displayed on the Servo Drive front panel and F012 is given as the AlarmCode (4001 hex).

None
Input the correct voltage.
Remove the phase-advancing
capacitor or UPS.
Measure the resistance of the
external resistor between the B1
and B2 terminals on the Servo
Drive. If the resistance is infinite,
the wiring is broken. Replace the
external resistor.
Change the Regeneration Resistor
based on the specified
regeneration resistance and the
calculated power (W).
Replace the Servo Drive.
