A5014 Alarm in ABB ACS550 Drive VFD

A5014 Alarm in the ABB ACS550 Drive VFD indicates that a keypad button is disabled because the drive is in a fault state. While an active fault exists, certain keypad functions are blocked to prevent unintended operation. The alarm will clear automatically after the fault has been reset successfully.

A5014 Alarm in ABB ACS550 Drive VFD


Possible Causes

  • The drive has an active fault.
  • A previous fault has not been reset.
  • A protective trip has disabled keypad operation.
  • The drive is waiting for the fault to be acknowledged.
  • The drive is in a fault lockout condition.

Solutions

  1. Check the active fault displayed on the drive.
  2. Identify and correct the cause of the fault.
  3. Reset the fault using the keypad, digital input, fieldbus, or by cycling power (if appropriate).
  4. After the fault is cleared, verify that the keypad buttons operate normally.

Additional Information

The A5014 alarm is informational and does not indicate a hardware failure. It simply informs the user that one or more keypad buttons cannot be used because the drive is currently faulted.

The alarm disappears automatically once:

  • The underlying fault has been corrected.
  • The fault has been successfully reset.

If A5014 remains after resetting the drive, check whether another active fault is still present.

Common Symptoms

  • Display shows A5014 Alarm.
  • Keypad buttons do not respond.
  • Drive cannot be started from the keypad.
  • Another active fault is displayed.
  • Normal keypad operation returns after the fault is cleared.

Recommended Troubleshooting Sequence

  1. Verify that the displayed alarm is A5014.
  2. Check the drive for any active fault codes.
  3. Correct the cause of the active fault.
  4. Reset the fault.
  5. Confirm that the alarm has disappeared.
  6. Verify that the keypad buttons function normally.
  7. Restart the drive if required.
