Problems solved by technology

[0006] In particular, the existing "EtherCAT-ProfiBUS protocol conversion technology" cannot be directly transplanted to the "industrial computer-motor" connection, but needs to go through several complicated debugging; and how to debug, the inventor searched (including: EPO database, CNKI database, HIMMPAT database, Wanfang database, Baidu), but no literature has disclosed

Abstract

The invention discloses a numerically-controlled machine tool communication heterogeneous feeding system and a debugging method thereof, belongs to the field of numerically-controlled machine tool servo control, and is characterized in that feeding system hardware is divided into four parts: an industrial personal computer, a communication protocol conversion module, a servo driver and a servo motor. Upper computer control software is installed in the industrial personal computer and supports an EtherCAT field bus protocol, the servo driver and the servo motor support a ProfiBUS field bus protocol, debugging is conducted through lower computer control software, and the communication protocol conversion module can achieve conversion of an upper computer communication protocol and a lower computer communication protocol. The debugging method is divided into three parts: upper computer control software configures the communication protocol conversion module, lower computer control software configures the servo driver and sets parameters of a position loop and a speed loop of the feeding system. By means of the system and the debugging method, high-performance motion control over the communication heterogeneous feeding system in a numerically-controlled machine tool can be achieved.

Description

technical field [0001] The present invention relates to the field of servo control of CNC machine tools, and more specifically, relates to a communication heterogeneous feeding system of CNC machine tools and a debugging method thereof. Background technique [0002] EtherCAT (Ethernet Control Automation Technology) is an open-architecture industrial fieldbus developed by Beckhoff, Germany. It is widely used in the field of automation because of its low communication jitter and low hardware cost. The ProfiBUS protocol was developed by Siemens AG of Germany, and it is used in servo drive control scenarios with high real-time requirements and high control precision requirements. [0003] At present, many open CNC systems are developed based on the EtherCAT communication protocol. Therefore, if you want to realize real-time control of the servo that supports the ProfiBUS protocol, you must open up the conversion and debugging process of the two protocols, so as to realize the hi...
