Abstract
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.
Claims3
A servo control system comprising:
- 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,
- wherein the delay memory includes a first memory having a short access delay time and a second memory having a long access delay time,
- wherein 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, and
- wherein the switching unit is switched such that
- when the learning period is longer than the delay time of the second memory, the second memory is selected, and
- when the learning period is equal to or shorter than the delay time of the second memory, the first memory is selected.
