Alarm Display: A. 100
Alarm Name: Over current (Heat Sink Overheated)
1. Situation at Alarm Occurrence: Occurred when the control power supply was turned ON.
Cause: The overload alarm has been reset by turning OFF the power too many times.
Corrective Actions: Change the method to reset the alarm.
Cause: The connection is faulty between the SERVOPACK board and the thermostat switch.
Corrective Actions: Replace the SERVOPACK.
Cause: The SERVOPACK board fault occurred.
Corrective Actions: Replace the SERVOPACK.
2. Situation at Alarm Occurrence: Occurred when the main circuit power supply was turned ON or when an overcurrent occurred while the servomotor was running.
Cause: The connection between grounding and U, V, or W is incorrect.
Corrective Actions: Check and then correct the wiring.
Cause: The grounding line has contact with other teminals.
Corrective Actions: Check and then correct the wiring.
Cause: A short circuit occurred between the grounding and U, V, or W of the servomotor cable.
Corrective Actions: Repair or replace the servomotor cable.
Cause: A short circuit occurred between phase U, V, or W of the servomotor.
Corrective Actions: Repair or replace the servomotor cable.
Cause: The wiring of the regenerative resistor is incorrect.
Corrective Actions: Check and then correct the wiring.
Cause: A short circuit occurred between the grounding and U, V, or W of the SERVOPACK.
Corrective Actions: Replace the SERVOPACK.
Cause: A SERVOPACK fault occurred (current feedback circuit, power transistor or board fault).
Corrective Actions: Replace the SERVOPACK.
Cause: A short circuit occurred between the grounding and U, V, W of the servomotor.
Corrective Actions: Replace the servomotor.
Cause: A short circuit occurred between the grounding and U, V, W of the servomotor.
Corrective Actions: Replace the servomotor.
Cause: A fault occurred in the dynamic brake circuit.
Corrective Actions: Replace the SERVOPACK, and reduce the load, or reduce the number of rotations used.
Cause: The dynamic brake was activated too frequently, so a DB overload alarm occurred.
Corrective Actions: Replace the SERVOPACK, and reduce the DB operation frequency.
Cause: The overload alarm has been reset by turning OFF the power too many times.
Corrective Actions: Change the method to reset the alarm.
Cause: The overload or regenerative power exceeds the regenerative resistor’s capacity.
Corrective Actions: Reconsider the load and operation conditions.
Cause: The direction or the distance of the SERVOPACK to other devices is incorrect. Heat radiation of the panel or heat around the panel occurred.
Corrective Actions: The ambient temperature for the SERVOPACK must be 55-degrees centigrade or less.
Cause: A SERVOPACK fan fault occurred.
Corrective Actions: Replace the SERVOPACK.
Cause: A SERVOPACK fault occurred.
Corrective Actions: Replace the SERVOPACK.
