A.d10:
Motor-load Position
Error Overflow
Motor rotation direction and
external encoder installation
direction are opposite.
Check the servomotor rotation
direction and the external encoder
installation direction.
Install the external encoder in the
opposite direction, or change the
setting of the external encoder
usage method (Pn002.3) to reverse
the direction.
Mounting of the load (e.g., stage)
and external encoder joint instal-
lation are incorrect.
Check the external encoder
mechanical connection.
Check the mechanical joints.
A.E02:
MECHATROLINK
Internal
Synchronization
Error 1
MECHATROLINK transmission
cycle fluctuated.
−
Remove the cause of transmission
cycle fluctuation at host controller.
A fault occurred in the SERVO-
PACK.
−
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
A.E40:
MECHATROLINK
Transmission Cycle
Setting Error
Setting of MECHATROLINK
transmission cycle is out of speci-
fications range.
Check the MECHATROLINK
transmission cycle setting. Set the transmission cycle to the
proper value.
A.E50:
MECHATROLINK
Synchronization Error
WDT data of host controller was
not updated correctly. Check the WDT data updating for
the host controller. Update the WDT data at the host
controller correctly.
A fault occurred in the SERVO-
PACK.
−
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
A.E51:
MECHATROLINK
Synchronization
Failed
WDT data of host controller was
not updated correctly at the syn-
chronization communications
start, and synchronization com-
munications could not start.
Check the WDT data updating for
the host controller. Update the WDT data at the host
controller correctly.
A fault occurred in the SERVO-
PACK.
−
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
A.E60:
MECHATROLINK
Communications error
(Reception error)
MECHATROLINK wiring is
incorrect. Check the MECHATROLINK wir-
ings.
Correct the MECHATROLINK wir-
ing.
Connect the terminator correctly.
MECHATROLINK data recep-
tion error occurred due to noise
interference.
−
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.
A fault occurred in the SERVO-
PACK.
−
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
A.E61:
MECHATROLINK
Transmission Cycle
Error
(Synchronization
interval error)
MECHATROLINK transmission
cycle fluctuated. Check the MECHATROLINK
transmission cycle setting. Remove the cause of transmission
cycle fluctuation at host controller.
A fault occurred in the SERVO-
PACK.
−
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
