Abstract: PURPOSE:To always effectively and rapidly perform an initial reset confirming operation by storing and holding a phase exciting state in a memory irrespective of ON/OFF of a main power source. CONSTITUTION:An initial position exciting phase is written in an E<2>PROM at the times of assembling and regulating. The initial position exciting phase is first read from the E<2>PROM at the time of operation. A motor is turned ON in the exciting phase, and held at the initial position. Then, if an initial position sensor is not turned ON, the motor is driven by -1 step toward the initial position. This operation is repeated until the sensor is turned ON. If it is turned ON, the motor is stopped to be turned OFF. If the sensor is already turned ON, the motor is once driven toward +1 step. This is repeated until the sensor is turned OFF, and it is then stepped to the sensor side. When the sensor is turned ON, the motor is turned OFF. Thus, an initial reset confirming operation can be always effectively and rapidly performed.
