A servo control system according to the present invention includes a servo control device for driving a driven body that operates periodically using a servomotor; and a learning controller for generating correction data based on a location deviation with respect to a uniform command pattern, and storing the correction data in delay memory and correcting the location deviation. The delay memory includes first memory having a short access delay time and second memory having a long access delay time. The servo control device includes a switching unit for assigning one of the first memory and the second memory to the learning controller, depending on a learning period according to the command pattern.
