available and allows checking success of the starting phase. The turning direction of the start-up

sequence automatically determines the direction of motor operation with hallFX. You can check

velocity and direction, as soon as valid hallFX signals are available.

When you experience commutation sequence errors during motor operation, probably motor velocity

has dropped below the lower threshold. In this case, the motor could be restarted in forward control

mode, or you could switch to forward control mode on the fly.
