Abstract:
1. A motor control method in a device which drives a mechanism using a motor as a power source, comprising: a setting step of setting a driving parameter for the motor; a profile generation step of, in executing driving of the motor, generating a position profile and a speed profile of the driving in accordance with a target position and the driving parameter set in said setting step; a tracking control step of controlling the driving of the motor by dividing the driving into a plurality of regions including an acceleration region, a deceleration region and a positioning region and driving the motor in the acceleration region and the deceleration region in accordance with the position profile and driving the motor in the positioning region in accordance with the speed profile; an evaluation step of, at an end of the driving, evaluating the driving parameter by using a result of actual driving and a predetermined value; and a changing step of changing the driving parameter used in the positioning region in accordance with a result of evaluation.
