Abstract

PURPOSE:To shorten the fixed position stop time by estimating a main shaft rotational position by using a motor shaft rotational position signal and a motor/main shaft change gear ratio, and executing a position control to the vicinity of the stop position. CONSTITUTION:A main shaft rotational position controller 11 receives a signal of a main shaft position detector 9 consisting of a magnetic emission body 7 attached to a main shaft 5 and a magnetic sensor 8 attached to a fixed part of the main shaft 5, as a main shaft origin signal through a position controller 10. Said signal is multiplied by a motor shaft rotating signal of a speed detection use pulse encoder 3 of a motor 2, and a change gear ratio, by which a main shaft rotational position signal is generated, and based on this signal, a position control of the first position control loop consisting of a position control loop selecting switch 17b, a speed command selecting switch 16a, a motor controller 1, the motor 2, and the pulse encoder 3 is executed. In such a way, the man shaft rotational position can be estimated, and the fixed position stop can be executed within one rotation from an arbitrary stop position.
