Therefore, the output of the rotational direction detector is low, when the spindle rotates forward, and high in the reverse rota-
tion.
6. Reverse Rotation Prevention
When the output of the OR Gate, A is LOW, it steers all the output current of the current sense Amp to the Gain Controller
zero. The output current of the Driver becomes zero and the motor stops.
As in the state of the forward rotation, the D-F/F output, Q is HIGH and the motor rotates normally. At this state, if the
control input is changed such that EC>ECR, then the motor rotates slowly by the reverse commutation in the Driver. When
the motor rotates in reverse direction, the D-F/F output becomes Low and the OR Gate output, becomes LOW. This
prevents the motor from rotating in reverse direction. The operation principle is shown in the table and the flow chart.
