FF61 ID Run Fault in ABB ACS880 Drive

FF61 ID Run in the ABB ACS880 Drive indicates that the Motor Identification (ID) Run did not complete successfully. The ACS880 performs an ID Run to identify the motor's electrical characteristics and create an accurate motor model for optimal speed, torque, and control performance. If the identification process is interrupted, incomplete, or unsuccessful, the drive generates Fault FF61.

This fault generally indicates a problem with the motor data, motor condition, control configuration, or ID Run procedure, rather than a fault in the drive hardware itself.

Possible Causes

  • Motor ID Run was interrupted before completion.
  • Incorrect motor nameplate data entered in Parameter Group 99 – Motor Data.
  • Motor shaft is mechanically locked.
  • External control system interfered with the ID Run.
  • Incorrect ID Run type selected.
  • Motor wiring fault.
  • Loose motor power connections.
  • Incorrect motor parameter configuration.
  • Motor not suitable for the selected ID Run.
  • Load preventing successful motor identification.
  • Brake preventing motor rotation during the ID Run.
  • Insufficient power supply during the ID Run.
  • Communication interruption during the identification process.
  • Internal drive control error.
  • Motor or drive hardware fault.

Solutions

  • Cycle power to the drive (and the control unit if powered separately).
  • Verify all motor nameplate data in Parameter Group 99 – Motor Data.
  • Confirm the motor voltage, current, frequency, speed, and power ratings are entered correctly.
  • Ensure no external control system is connected to or controlling the drive during the ID Run.
  • Verify the motor shaft can rotate freely if the selected ID Run requires rotation.
  • Remove any mechanical load if recommended for the selected ID Run.
  • Release the mechanical brake if applicable.
  • Inspect the motor wiring for loose or incorrect connections.
  • Select the appropriate ID Run type for the application.
  • Repeat the Motor ID Run.
  • Verify the incoming power supply is stable.
  • Check the motor for mechanical or electrical faults.
  • Replace defective motor or wiring components if necessary.
  • Contact ABB technical support if the ID Run continues to fail.

Additional Information

The ABB ACS880 uses a Motor Identification (ID) Run to measure the motor's electrical characteristics and create an accurate internal motor model. This model allows the drive to provide precise speed control, torque control, and motor protection.

During the ID Run, the drive may perform tests such as:

  • Measuring stator resistance.
  • Measuring motor inductance.
  • Identifying magnetic characteristics.
  • Verifying motor parameters.
  • Measuring rotor characteristics (depending on the selected ID Run type).

If the drive cannot successfully complete these measurements, it generates Fault FF61.

Common reasons include:

  • Incorrect motor nameplate values entered in Parameter Group 99 – Motor Data.
  • A mechanically locked motor shaft.
  • External PLC or automation system interfering with the ID Run.
  • An unsuitable ID Run type selected for the application.

ABB also recommends cycling power to both the drive and the control unit (if powered separately) before repeating the ID Run.

Unlike motor operation faults, FF61 occurs during the motor identification procedure, preventing the drive from creating an accurate motor model.

Common Symptoms

  • Drive trips with Fault FF61.
  • ID Run stops before completion.
  • Motor fails to rotate during the ID Run when rotation is expected.
  • Commissioning cannot be completed.
  • Drive refuses to enter normal operation after a failed ID Run.
  • Fault appears immediately after starting the ID Run.
  • Motor parameters cannot be identified.
  • Mechanical brake prevents shaft movement.
  • External PLC interrupts the ID Run sequence.
  • Fault remains until a successful ID Run is completed.

Recommended Troubleshooting Sequence

  1. Cycle power to the drive and control unit if required.
  2. Verify all values in Parameter Group 99 – Motor Data.
  3. Confirm the motor nameplate information is entered correctly.
  4. Disconnect or disable any external control system during the ID Run.
  5. Verify the motor shaft is free to rotate.
  6. Release the mechanical brake if applicable.
  7. Remove the mechanical load if recommended.
  8. Inspect motor power wiring.
  9. Verify stable incoming power.
  10. Select the correct ID Run type.
  11. Repeat the Motor ID Run.
  12. Inspect the motor for electrical or mechanical faults.
  13. Replace defective components if necessary.
  14. Verify successful completion of the ID Run.
  15. Contact ABB technical support if the fault persists.

Preventive Maintenance Tips

  • Enter accurate motor nameplate data before performing an ID Run.
  • Verify Parameter Group 99 – Motor Data during commissioning.
  • Disconnect external PLC or automation control during the ID Run unless specifically supported.
  • Ensure the motor shaft rotates freely before selecting a rotating ID Run.
  • Release mechanical brakes before performing rotating identification.
  • Use the appropriate ID Run type recommended by ABB for the application.
  • Inspect motor wiring and terminals before commissioning.
  • Maintain stable power during the ID Run.
  • Save a backup of verified motor parameters after successful commissioning.
  • Record recurring ID Run failures to assist long-term diagnostics.

Proper verification of Parameter Group 99 – Motor Data, correct selection of the Motor ID Run type, removal of external control interference, and confirmation that the motor shaft is free to rotate will help prevent recurring FF61 ID Run faults in ABB ACS880 drives, ensuring accurate motor identification, reliable speed and torque control, and dependable long-term operation of the drive system.
