Cause
The ambient operating tempera-
ture around the servomotor is too
high.
The motor load is greater than the
rated load.
An encoder fault occurred.
A SERVOPACK fault occurred.
The current detection circuit for
phase U is faulty.
The current detection circuit for
phase V is faulty.
The detection circuit for the cur-
rent is faulty.
The servomotor main circuit
cable is disconnected.
SERVOPACK MECHA-
TROLINK communication sec-
tion fault.
MECHATROLINK data recep-
tion error occurred due to noise
interference.
SERVOPACK MECHA-
TROLINK communication sec-
tion fault.
A SERVOPACK fault occurred.
A SERVOPACK fault occurred.
A SERVOPACK fault occurred.
A SERVOPACK fault occurred.
Investigative Actions
Measure the ambient operating tem-
perature around the servomotor.
Check the accumulated load ratio
(Un009) to see the load.

Corrective Actions
The ambient operating temperature
must be 40°C or less.
The motor load must be within the
specified range.
Restart the SERVOPACK. If the
alarm still occurs, the servomotor
may be faulty. Replace the servo-
motor.
Restart the SERVOPACK. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Restart the SERVOPACK. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Restart the SERVOPACK. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Restart the SERVOPACK. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Correct the servomotor wiring.
Restart the SERVOPACK. 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.
Restart the SERVOPACK. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Restart the SERVOPACK. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Restart the SERVOPACK. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Restart the SERVOPACK. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
Restart the SERVOPACK. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
