* Sensor based phasing go wrong if commutation sensor is improperly wired, or not outputting signals that are expected by drive. This can yield randomness in initialization (S may seem random after each power on). | * Sensor based phasing go wrong if commutation sensor is improperly wired, or not outputting signals that are expected by drive.

* To verify if sensored method works, try starting up drive after motor shaft has been set at different angle on each test, and then try drive the motor. I.e. first power on it at angle 0°, then 5°, then 10°, then 15° and perhaps few random angles too. If motor stays stable and operates properly after each power on at any angle, then phasing is working correctly. | * To verify if sensored method works, try starting up drive after motor shaft has been set at different angle on each test, and then try drive the motor.
