ABSTRACT:
A motor control apparatus comprises a speed command signal generating section generating a speed command signal for accelerating or decelerating a control object in accordance with a predetermined pattern. A position control section controls the position of the control object and a speed control section controls the speed of the control object by accelerating or decelerating the control object in accordance with the speed pattern. An encoder observes the present position of the control object. The load inertia of the control object is identified based on a positional deviation between the command position of the control object and the present position obtainable from the encoder at the time the speed command generated from the speed command signal generating means becomes a predetermined speed.
