None
Cause and Assumed cause
correction
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).
The Regeneration Resistor wiring is
broken.
The External Regeneration Resistor
is not suitable.
The Servo Drive failed.
Attached None

Remedy
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.
