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

The invention realizes high speed communication and high precision synchronization and high reliability communication, and has goodexpansibility.

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...
