Abstract

PURPOSE:To control driving at high precision in no relation to the precision of assembly, by controlling the absolute phase angle of an angle encoder, and by adjusting the phase angle of a motor rotor and the phase angle of the angle encoder finely. CONSTITUTION:To a lead angle command value, a lead angle bias value from a lead angle bias circuit 17 is added, and the phase angles of a stepping motor rotor and an angle encoder 11 are controlled. By this method, a lead phase angle is change-ever-controlled, and the absolute phase angle of the angle encoder 11 is adjusted, and a fitting error is automatically corrected. Accordingly, in no relation to fitting precision, driving can be controlled at high precision, and the work of its assembly is realized as simply as possible.
