Abstract

PURPOSE:To improve the reliability of a positioning control by operating a main shaft rotational position from a main shaft origin position signal by a magnetic sensor, a signal of a speed detection use pulse encoder of a main shaft motor, and a change gear ratio of the main shaft and the motor, which has been set to a change gear ratio constant setting device of a position controller, and executing a stop control to a given arbitrary rotational position. CONSTITUTION:By executing a positioning control to a position of an arbitrary main shaft rotational position command, by using a main shaft origin signal by a position detector 9, a change gear ratio of a change gear ratio constant setting device 12 of a position controller 11, and a main shaft rotational position signal obtained by operating a motor shaft rotational position by a pulse encoder 3 an arbitrary position stop is executed without a main shaft position detection pulse encoder. In a such a way, by using a conventional magnetic emission body and a magnetic sensor, as a main shaft rotational position detector, it is possible to stop at an arbitrary main shaft rotational position, and the reliability is improved.
