Corrective Actions
The external absolute encoder may
be faulty. Refer to the encoder man-
ufacturer's instruction manual for
corrective actions.
Keep the external encoder below its
maximum speed.
Replace the external encoder.
Turn the power supply to the SER-
VOPACK OFF and ON again. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Turn the power supply to the SER-
VOPACK OFF and ON again. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Turn the power supply to the SER-
VOPACK OFF and ON again. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Correct the servomotor wiring.
Turn the power supply to the SER-
VOPACK OFF and ON again. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Take measures against noise. Check
the MECHATROLINK communi-
cations cable and FG wiring and
take measures such as adding ferrite
core on the MECHATROLINK
communications cable.
Turn the power supply to the SER-
VOPACK OFF and ON again. If the
alarm still occurs, the SERVO-
PACK 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 to the SER-
VOPACK OFF and ON again. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Turn the power supply to the SER-
VOPACK OFF and ON again. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
