MOTION CONTROL SYSTEM USING ASYNCHRONOUS COMMUNICATION AND CONTROLLER AND METHOD THEREOF

摘要

Present invention provides a motion control system using asynchronous communication, and the controller and methods thereof. The motion control system include: a first controller, being adapted for preparing a multiple of data sequentially at a series of first clocks and keeping transmitting the data at a series of second clocks until it receives a confirmation; a second controller, being adapted for receiving the data and acknowledging correct receipt of the data by returning the confirmation; wherein; an interval among the series of first clocks is longer than an interval among the series of the second clocks. By having the configuration as above, it can provide at least one of the technical effects as: 1. asynchronous communication between the first controller and the second controller; 2. the two controllers with different clock rates can communicate with each other; 3. avoidance of lost data by retransmitting the data at a frequency higher than the frequency at which the data are prepared or are to be consumed; 4. the reuse of the interval between the first clocks for transmission of the data at a series of the second clocks.
