Display Detail name
Cause
Check method
Check result
Action
32.1
(1) The servo amplifier is
malfunctioning.
It occurs.
Replace the servo
amplifier.
Disconnect the servo
motor power cables (U,
V, and W) and check if
the alarm occurs.
It does not occur.
Check (2).
Overcurrent
detected at
hardware
detection circuit
(during
operation)
(2)
It is shorted.
Replace the servo motor
power cable.
A ground fault or short
occurred at the servo
motor power cable.
Check if only the servo
motor power cable is
shorted.
It is not shorted.
Check (3).
(3) The servo motor is
malfunctioning.
A ground fault is
occurring.
Replace the servo motor.
Disconnect the servo
motor power cables on
motor side, and check
insulation of the motor
(between U, V, W, and
).
A ground fault is not
occurring.
Check (4).
(4) The dynamic brake is
malfunctioning.
It occurs.
Replace the servo
amplifier.
Check if the error occurs
when you turn on the
servo-on command.
It does not occur.
Check (5).
(5)
It is not correct.
Wire it correctly.
The connection
destination of the
encoder cable is
incorrect.
Check if the encoder
cable is connected
correctly.
It is correct.
Check (6).
(6) Something near the
device caused it.
Check the noise,
ambient temperature,
etc.
It has a failure.
Take countermeasures
against its cause.
32.2
(1) The servo gain is high.
Check if an oscillation is
occurring.
An oscillation is
occurring.
Reduce the speed loop
gain ([Pr. PB09]).
An oscillation is not
occurring.
Check (2).
Overcurrent
detected at
software
detection
function (during
operation)
(2) The servo amplifier is
malfunctioning.
It occurs.
Replace the servo
amplifier.
Disconnect the servo
motor power cables (U,
V, and W) and check if
the alarm occurs.
It does not occur.
Check (3).
(3)
It is shorted.
Replace the servo motor
power cable.
A ground fault or short
occurred at the servo
motor power cable.
Check if only the servo
motor power cable is
shorted.
It is not shorted.
Check (4).
(4) The servo motor is
malfunctioning.
A ground fault is
occurring.
Replace the servo motor.
Disconnect the servo
motor power cables on
motor side, and check
insulation of the motor
(between U, V, W, and
).
A ground fault is not
occurring.
Check (5).
(5)
It is not correct.
Connect it correctly.
The connection
destination of the
encoder cable is
incorrect.
Check if the encoder
cable is connected
correctly.
It is correct.
Check (6).
(6) Something near the
device caused it.
Check the noise,
ambient temperature,
etc.
It has a failure.
Take countermeasures
against its cause.
32.3 Overcurrent
detected at
hardware
detection circuit
(during a stop)
Check it with the check method for [AL. 32.1].
32.4 Overcurrent
detected at
software
detection
function (during
a stop)
Check it with the check method for [AL. 32.2].
