  • Publication number: 20230152782
    Abstract: By controlling an operation of one reference axis using a control program, a controller operates another axis in synchronization with the reference axis. The controller generates shift information indicating an operation timing of another axis with respect to the reference axis, and determines a timing of outputting a movement amount related to each of the plurality of axes according to the generated shift information. Then, the controller outputs a movement amount of an axis, for which it is determined that it is a timing to output the movement amount, and buffers a movement amount of an axis, for which it is determined that it is not a timing to output the movement amount.
