Forward rotation at EC < ECR
Rotating speed is decreased due to reverse torque at EC >ECR. (Motor still rotates forward)
At the moment that the motor rotates in reverse, the reverse rotation preventer makes the output power transistor open.
Rotating reverse at short time due to motor inertia
Stop within 1/6 turn reverse rotating
