Problems solved by technology

[0004] like figure 1 As shown, in the current AC servo system, CANopen communication is usually realized through the combination of FPGA+MCU. In this implementation method, data interaction between FPGA and MCU is required, the design is complex, the development cycle is long, and the portability is poor. This implementation method needs to occupy more resources and cannot guarantee the parallel processing speed, which will affect the flexibility of the control. Especially in the motor servo control system, the response is slow, the positioning is not accurate, and the error is large, which is not conducive to ensuring the reliability of the system.

Description

technical field [0001] The present application relates to the technical field of industrial field bus, in particular to an IP core, an FPGA chip, an AC servo driver and a communication method. Background technique [0002] CANopen is a high-level communication protocol based on the Controller Area Network (CAN), including communication sub-protocols and device sub-protocols. Its protocol content is completely open and widely used in I / O equipment, servo drive equipment, measurement and control Instruments, programmable equipment, encoders, medical equipment, elevator control, extrusion equipment, municipal vehicles and other industrial control industries. Using the motion control sub-protocol in the CANopen protocol set, the CANopen communication interface development for industrial control equipment such as inverters and servo drives can be realized. [0003] Specifically, the integration of CANopen fieldbus technology into the AC servo system can make full use of the phys...
