Corrective Actions
Keep the external encoder below its
maximum speed.
Replace the external encoder.
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
Correct the servomotor wiring.
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
Confirm that the servomotor is cor-
rectly wired.
If the alarm still occurs after turning
the power OFF and then ON again,
even though the servomotor is cor-
rectly wired, the servomotor may be
faulty. Replace the servomotor.
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK or con-
verter may be faulty. Replace the
SERVOPACK or converter.
