Abstract:
A method of controlling a motor by dividing the controlling into a plurality of regions including an acceleration region and a constant-velocity region in a device in which a mechanism is driven using the motor as a power source, comprising:a command value output step of outputting a velocity command value by modifying a velocity command value defined in a preset velocity profile, based upon a preset position profile and information relating to position of the mechanism within the acceleration region; a servo-control step of outputting command information regarding the motor based upon the velocity command value modified in said command value output step and information regarding velocity of the mechanism; and a driving signal generating step of generating a driving signal of the motor, based upon the command information, wherein in said command value output step, the velocity command value based upon the preset velocity profile is outputted within the constant-velocity region.
