Assumed cause
There is a short-circuit, ground
fault, or contact failure on the U,
V, or W motor cable
There is a short-circuit on the wir-
ing of External Regeneration
Resistor or the resistance value
is small
Cause and
correction
The insulation resistance failed
between the U, V, or W motor
cable and the motor ground wire
Servo Drive failure

Correction
Correct the connection of the U, V,
or W motor cable.
If there is a short-circuit on the wir-
ing of External Regeneration
Resistor, correct the wiring.
Replace the motor.
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.
Use the recommended External
Regeneration Resistor. If a resis-
tance value of the External Regen-
eration Resistor is small,
excessive current will flow into the
power module and cause a failure.
Confirm that the insulation resis-
tance is insulated between the U,
V, and W motor cable and the
motor ground wire before using the
motor.
Do not perform Servo ON/OFF fre-
quently. Doing so may cause a
Servo Drive failure.
