Abstract

The invention provides a multi-axis motion control system comprising a master-slave mode open type hardware system. The master-slave mode open type hardware system is composed of a PC and a multi-axis motion controller, wherein the PC serves as a master controller, and the multi-axis motion controller serves as a slave controller. The multi-axis motion controller controls an alternating current permanent magnet synchronous motor through a servo driver. The alternating current permanent magnet synchronous motor is connected with an optical-electricity encoder. The optical-electricity encoder detects operation states of the alternating current permanent magnet synchronous motor and transmits the operation states serving as a feedback signal to the multi-axis motion controller through the servo driver. The multi-axis motion control system overcomes the defects in the prior art, takes the advantages of abundant software resources of the PC and high-speed hardware of the multi-axis motion controller to the maximum extent, meets the requirements for real-time performance and high accuracy of the controller, and has universality.

Description

technical field [0001] The invention relates to a multi-axis motion control system, which belongs to the technical field of robot control. Background technique [0002] At present, in the face of the differentiation of industrial manufacturing and the individualization of product processing, traditional closed or semi-closed special motion controllers have gradually been unable to meet the growing industrial needs, and the development of open robot multi-axis motion control with strong compatibility Platforms are gaining more and more attention in related research fields. Today, the core component of the motion control system - the multi-axis motion controller has been widely used in various automation fields as an independent industrial automation control product, and is rapidly moving towards openness, modularization and generalization. develop. [0003] The open structure controller means that all levels of controller design are open to users, and users can easily expan...
