Abstract

The invention discloses an Ethernet networked connection device and system for realizing a non-networked servo. The Ethernet networked connection device comprises an outer shell in which a control panel is arranged; the control panel comprises a core panel and a servo driving interface panel, the core panel is movably connected with the servo driving interface panel via a servo interface panel insert pin; the outer shell is of a two-half type structure, and the middle parts of the outer shell are connected via a buckle; openings respectively matched with a net opening, a terminal board and a servo plug on the core panel are positioned on the outer shell; and a chute matched with the core panel is positioned on the inner wall of the outer shell, and heat radiating holes are arranged at the bottom part of the outer shell. According to the invention, a network communication, a servo control and a servo driving connector are integrated on a small module; the driver is not required to perform any change and plugged on the control interface of the general servo driver so that the real-time Ethernet communication function is added to the general servo drive and replaces the complex connecting method of the original traditional servo interface for realizing the networked connection of the system.

Description

technical field [0001] The invention relates to a traditional servo network connection device, in particular to an Ethernet network connection device and system for realizing non-network servo. Background technique [0002] In recent years, servo drive technology has developed rapidly in terms of control accuracy and operating speed, but the servo drive interface has long been in the stage of pulse quantity and analog signal control. The communication rate of this interface is low, and the control method is complicated. Serious It hinders the development of high-end servo technology. On the other hand, industrial control network has experienced the development from distributed control to fieldbus technology. Although fieldbus still occupies this dominant position, it is increasingly difficult to meet the requirements of interconnection and large-scale data transmission between intelligent devices in the factory because of its complicated protocol standards and low data tra...
