AFF6 Identification Run Warning in ABB ACS560 Drive

AFF6 – Identification Run in the ABB ACS560 Drive VFD indicates that a Motor Identification (ID) Run has been scheduled and will be performed at the next start command. This is an informative alarm/warning only and does not indicate a fault or malfunction.

AFF6 Identification Run Warning in ABB ACS560 Drive


During the next motor start, the drive will automatically execute the motor identification procedure to determine the motor characteristics required for optimum control performance.

Possible Causes

  • Motor ID Run has been requested during commissioning.
  • Motor parameters have been changed, requiring a new identification run.
  • Start-up or commissioning procedure is in progress.
  • Automatic motor identification has been enabled.

Solution

  1. Informative warning only.
  2. Start the drive to allow the Motor Identification (ID) Run to be completed.
  3. Ensure it is safe for the motor and connected equipment to perform the ID run before issuing the start command.
  4. If an ID run is not required, review the commissioning settings and cancel the pending identification run if appropriate.

Additional Information

The ABB ACS560 uses a Motor Identification (ID) Run to measure the electrical characteristics of the connected motor. The collected data allows the drive to optimize motor control, improve torque accuracy, and enhance overall performance.

The AFF6 warning simply informs the user that the identification process is pending and will begin automatically on the next start command.

This warning does not prevent normal drive operation unless the application requires the ID run to be completed first.

Common Symptoms

  • Drive displays AFF6 – Identification Run.
  • Motor has not yet completed an ID run.
  • Warning appears after commissioning or changing motor parameters.
  • Drive is waiting for the next start command.
  • No hardware fault is present.

Recommended Troubleshooting Sequence

  1. Verify that the displayed warning is AFF6.
  2. Confirm that an ID Run has been intentionally requested.
  3. Ensure the motor and driven machine can safely perform the identification run.
  4. Issue the next Start command.
  5. Allow the ID Run to complete without interruption.
  6. Confirm that the warning clears after successful completion.

Preventive Maintenance Tips

  • Perform the Motor ID Run during initial commissioning.
  • Re-run the ID procedure whenever the motor is replaced or significant motor parameters are changed.
  • Ensure accurate motor nameplate data is entered before starting the identification process.
  • Disconnect the driven load if recommended by ABB for the selected ID Run type.
  • Do not interrupt the ID Run once it has started.
  • Record completed commissioning procedures for future maintenance.
  • Follow ABB commissioning and preventive maintenance recommendations for the ACS560 Drive VFD.

The AFF6 – Identification Run warning is a normal commissioning message indicating that the Motor ID Run will occur at the next start. In most cases, no corrective action is required other than ensuring it is safe to start the motor and allowing the identification process to complete successfully.
