Reverse rotation detection circuit
By comparing the two phases of the Hall element signal, this circuit detects a state where the phases are
inverted, at which time the torque is reduced to 0. The detection accuracy is determined by the number of pulses
per rotation of Hall element output.
Note4: Due to its inertial force, the motor does not stop immediately after the torque is reduced to 0.
