Alarm Display: A. 510
Alarm Name: Over speed
1. Situation at Alarm Occurrence: Occurred when the control power supply was turned ON.
Cause: A SERVOPACK board fault occurred.
Corrective Actions: Replace the SERVOPACK.
2. Situation at Alarm Occurrence: Occurred when Servo was ON.
Cause: The order of phases U, V, and W in the servomotor wiring is incorrect.
Corrective Actions: Correct the servomotor wiring.
Cause: The encoder wiring is incorrect.
Corrective Actions: Correct the encoder wiring.
Cause: Malfunction occurred due to noise interference in the encoder
Corrective Actions: Take measures against noise for the encoder wiring.
Cause: A SERVOPACK fault occurred.
Corrective Actions: Replace the SERVOPACK.
3. Situation at Alarm Occurrence: Occurred when the servomotor started running or in a high speed run.
Cause: The order of phases U, V, and W in the servomotor wiring is incorrect.
Corrective Actions: Correct the servomotor wiring.
Cause: The encoder wiring is incorrect.
Corrective Actions: Correct the encoder wiring.
Cause: The servomotor cable shorts to ground.
Corrective Actions: Repair or replace the servomotor cable.
Cause: Malfunction occurred due to noise interference in the encoder wiring.
Corrective Actions: Take measures against noise for the encoder wiring.
Cause: The position or speed reference input is too large.
Corrective Actions: Reduce the reference value.
Cause: The setting of the reference input gain is incorrect.
Corrective Actions: Correct the reference input gain setting.
