摘要： PROBLEM TO BE SOLVED: To solve the problem that when a setting range in case of positioning is set to zero, and positioning to a target value is performed, a motor always vibrates bit by bit even after a driven body is positioned to the target value by the motor, and the driven body is moved beyond the setting range due to disturbance in conventional positioning.SOLUTION: When a current value where a positioning stage detected by a position sensor is positioned is within a first setting range, the setting range of the positioning stage is changed to a second setting range, and when the current value where the positioning stage detected by the position sensor is positioned is beyond the first setting range, the positioning stage is moved again so as to be positioned within the first setting range.
