Abstract
A motor stopping circuit is activated when a motor control circuit is stopped by a reset signal outputted from a reset circuit. This maintains an overrun angle small. As a result, a difference between a rotation angles measured when the motor control circuit is turned off and measured when the motor control circuit is turned on are small. Therefore, frequent origin setting operation is not required. This reduces sizes and manufacturing costs of a stopper and an actuator.
