Commutation offset could not be determined
Indramat · Indradrive
¿Qué significa F8011 ?
The IndraDrive failed to determine the commutation offset necessary for proper motor control during an automatic setup routine. This offset is crucial for aligning the rotor position with the stator field, and its absence prevents the drive from starting the motor correctly.
Causas comunes
- Incorrect motor wiring (phase sequence, shield).
- Faulty encoder or encoder feedback connection.
- Motor type or pole pair parameter mismatch.
- Mechanical issues preventing motor rotation during the commutation routine.
- Drive internal fault preventing current injection.
Pasos de reparación & Lista de verificación

- 1
Verify the motor power cable connections (U, V, W) and ensure they are correct according to the manual.
- 2
Check the encoder wiring for proper connection, shielding, and absence of damage.
- 3
Confirm that the motor type (e.g., S-0-0013) and pole pair count parameters (e.g., S-0-0014) match the connected motor's nameplate.
- 4
Ensure the motor can rotate freely without mechanical binding during the commutation process.
- 5
Perform an encoder test if supported by the drive, or replace the encoder if it's suspected to be faulty.
