14 00 Overcurrent
Error
The current flowing to
the motor exceeded the
protection level.
There is a short circuit,
ground fault, or contact
failure on the U, V, or W
motor cable.
Correct the connection of the U, V,
or W motor cable.
There is a short circuit
on the wiring of External
Regeneration Resistor.
Correct the wiring of External
Regeneration Resistor.
The insulation resis-
tance failed between the
U, V, or W motor cable
and the motor ground
wire.
Replace the motor.
False detection due to
the noise
Take noise countermeasures.
Servo Drive failure If this event occurs again after you
performed all corrections shown
above, replace the Servo Drive.
01 Power Mod-
ule Error
An error was detected in
the power module.
There is a short circuit,
ground fault, or contact
failure on the U, V, or W
motor cable.
Correct the connection of the U, V,
or W motor cable.
There is a short circuit
on the wiring of External
Regeneration Resistor,
or the value of resis-
tance became too small.
If there is a short-circuit on the wir-
ing of External Regeneration Resis-
tor, correct the wiring.
The insulation resis-
tance failed between the
U, V, or W motor cable
and the motor ground
wire.
Replace the motor.
Servo Drive failure If this event occurs again after you
performed all corrections shown
above, replace the Servo Drive.
