Abstract

The invention relates to a multi-shaft DC servo motor control system and a method based on an EPA (Ethernet for Plant Automation) field bus. The system comprises a main control upper computer and a plurality of DC servo drivers, wherein the main control upper computer is connected with the DC servo drivers through an EPA communication network and comprises an EPA main station communication module for data exchange with the DC servo drivers; the EPA main station communication module further comprises a plurality of first data sending areas and a plurality of first data receiving areas; and each DC servo driver comprises an EPA slave station communication module for data exchange with the EPA main station communication module, and the EPA slave station communication module further comprises a second data sending area and a second data second receiving area. The invention realizes high speed communication and high precision synchronization and high reliability communication, and has good expansibility.

Description

technical field [0001] The invention relates to the field of servo motor control, in particular to a multi-axis DC servo motor control system and method based on EPA field bus. Background technique [0002] The multi-axis DC servo motor control system is widely used in the actual production process. In the production process of batching, transmission and humanoid robots, multiple DC servo motors are required to drive, and the coordinated control between multiple servo motors It directly affects the quality of the production process and the motion performance of the robot. For the control of this type of motion axis, the traditional multi-axis DC servo motor motion control system relies on mechanical cams and gears. However, this control system requires complex mechanical design to achieve multi-axis coordinated motion, resulting in large mechanical losses and maintenance. inconvenient. Therefore, the multi-axis DC servo motor control system based on various fieldbus techno...

Problems solved by technology

However, the existing multi-axis DC servo motor control systems based on fieldbus technology cannot realize direct centralized monitoring and seamless access to the factory information Ethernet, so that it is impossible to realize the comprehensive automation of industrial enterprises from the bottom of the field in the intelligent factory system. The communication network platform from the equipment layer to the upper control layer and the management layer is based on the unification of Ethernet technology, which makes the system expandability poor
