Correct the wiring of External
Regeneration Resistor.
Replace the motor.
Take noise countermeasures.
If this event occurs again after you
performed all corrections shown
above, replace the Servo Drive.

Prevention
Confirm that the motor cables are
not broken and connect them cor-
rectly.
Wire the External Regeneration
Resistor correctly when using it.
Confirm that the insulation resis-
tance is insulated between the U,
V, and W motor cable and the
motor ground wire before connect-
ing and using the motor.
Take noise countermeasures
because excessive noise may
cause false detection.
Do not perform Servo ON/OFF fre-
quently. Doing so may cause a
Servo Drive failure.
