Abstract

PURPOSE:To stop a body securely through the attraction of a small electromagnet while utilizing a storage device for phase difference detection, by nearly equalizing a speed at a home position to zero by driving the body forward after driving it in the return direction. CONSTITUTION:When the variation speed of a body is controlled by an output having polarity and magnitude which correspond to a phase difference between a reference signal and a signal which corresponds to the displacement of the body, command codes for return drive and forward drive are stored as control data in an ROM27 for reference code generation successively instead of reference data during the returning operation of the body. Then, an output which has polarity and magnitude corresponding to readout data from the ROM27 is generated by an ROM25 for phase difference detection without reference directly to feedback data from the displacement of the said body, and the body is driven in the return direction for a constant time and then driven forward to nearly equalize the speed at a home position to zero. Thus, the body is stopped by attraction securely by using a small electromagnet.
