Alarm Display: A. 320.
Alarm Name: Regenerative Overload.
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 the main circuit power supply was turned ON.
Cause: The power supply voltage is 270 V or more.
Corrective Actions: Correct the input voltage.
3. Situation at Alarm Occurrence: Occurred during normal operation (large increase of regenerative resistor temperature).
Cause: The regenerative energy is excessive, and the regenerating state continued.
Corrective Actions: Select a proper regenerative resistance capacity, or reconsider the load and operation conditions.
4. Situation at Alarm Occurrence: Occurred during normal operation (small increase of regenerative resistor temperature).
Cause: The setting of parameter Pn600 is smaller than the external regenerative resistor’s capacity.
Corrective Actions: Correct the set value of parameter Pn600.
Cause: A SERVOPACK fault occurred.
Corrective Actions: Replace the SERVOPACK.
5. Situation at Alarm Occurrence:
Cause: The regenerative energy is excessive.
Corrective Actions: Select a proper regenerative resistance capacity, or reconsider the load and operation conditions.
