Abstract

See full text

A motor control apparatus includes a high-resolution encoder for position control and a low-resolution encoder for velocity control, position control means for generating a velocity command in accordance with a difference between a given position command and the output of the high-resolution encoder, and velocity control means for generating a current command in accordance with a difference between the velocity command and a detected velocity that is based upon the output of the low-resolution encoder. A velocity control cycle based upon the velocity control means is made faster than a position control cycle based upon the position control means.
