A1D

Alarm code A1D means .

Cause analysis: 1. Ambient temperature is too high; 2. Operation was performed after repeatedly resetting the overload alarm by switching off the power; 3. Load is excessive, or regenerative processing capacity was exceeded during operation; 4. The drive installation orientation or spacing from other drives is unreasonable; 5. Drive fault

Remedy:

1. Measure the ambient temperature with a thermometer, or confirm operating conditions through the drive's ambient monitoring settings. Improve the drive installation conditions and lower the ambient temperature.

2. Use the alarm display to confirm whether an overload alarm has occurred. Change the alarm reset method.

3. Check the operating load through the accumulated load ratio, and check regeneration processing capacity through the regenerative load ratio. Reconsider the load conditions and operating conditions.

4. Confirm the drive installation status. Install it according to the drive installation standards.

5. Switch the drive power on again. If the alarm still occurs, the drive may be faulty. Replace the drive.
