A582 Auxiliary Fan Missing Warning in ABB ACS560 Drive

A582 – Auxiliary Fan Missing in the ABB ACS560 Drive VFD indicates that the auxiliary cooling fan (IP55 internal fan) is not operating correctly. The fan may be stuck, disconnected, or faulty, preventing proper cooling of the drive. This is an alarm/warning, allowing corrective action before overheating can occur.

A582 Auxiliary Fan Missing Warning in ABB ACS560 Drive


The warning may also appear during commissioning if the drive front cover is removed, even when the corresponding fault is disabled.

Possible Causes

  • Auxiliary cooling fan (IP55 internal fan) is stuck.
  • Auxiliary fan is disconnected.
  • Faulty auxiliary cooling fan.
  • Loose or damaged fan wiring.
  • Front cover is removed or not properly secured.
  • Fan connector not fully inserted.
  • Internal cooling system issue.

Solutions

1. Check the Auxiliary Code

  • Read the auxiliary code to obtain additional diagnostic information.

2. Check the Auxiliary Fan

  • Verify that the auxiliary cooling fan is operating normally.
  • Inspect the fan wiring and connector for loose or damaged connections.

3. Replace the Faulty Fan

  • Replace the auxiliary fan if it is defective or not rotating.

4. Check the Front Cover

  • Make sure the front cover of the drive is correctly installed and tightened.

Note:
If the drive is being commissioned with the front cover removed, this warning can be generated even if the corresponding fault has been disabled.

Additional Information

The ABB ACS560 continuously monitors the operation of the IP55 internal auxiliary cooling fan. If the fan does not operate or the drive detects that the cover is removed, A582 – Auxiliary Fan Missing is generated.

Typical causes include:

  • Fan failure.
  • Fan disconnected.
  • Front cover removed during commissioning.
  • Loose fan connector.

This warning should be corrected promptly to ensure proper cooling and prevent overheating faults.

Common Symptoms

  • Drive displays A582 – Auxiliary Fan Missing.
  • Auxiliary cooling fan is not running.
  • Warning appears during commissioning with the cover removed.
  • Reduced cooling performance.
  • Possible overheating if the condition continues.
  • Drive continues operating but indicates a cooling warning.

Recommended Troubleshooting Sequence

  1. Verify that the displayed alarm is A582.
  2. Check the auxiliary code.
  3. Inspect the auxiliary cooling fan.
  4. Verify fan wiring and connectors.
  5. Confirm that the fan rotates freely.
  6. Replace the fan if defective.
  7. Ensure the front cover is properly installed and tightened.
  8. Reset the warning and confirm normal operation.
