PROBLEM TO BE SOLVED: To provide a servo control system, which can automatically change the control profile in response to the confirmation of the deterioration and a predetermined condition of a part. SOLUTION: An image forming device is provided with a control unit and a movable part, which includes a photosensitive member and a copy sheet carrying unit, and the control unit includes a main controller 68 and a servo system connected to each other through a serial command bus 70, and the servo system is electrically connected to the predetermined movable part, and the servo system is provided with a control profile for indicating the movement of the predetermined movable part, and the control profile includes an acceleration, a deceleration and a constant speed part. The main controller 68 is provided with a logic for monitoring the operation of the servo system in a predetermined condition and for performing the down-load of a change through the serial command bus 70 in response to the detection of the predetermined condition so as to automatically change the selective part of the control profile corresponding to the predetermined servo system. |
