Problems solved by technology

[0016] At present, a position sensor interface can only implement one sensor communication protocol, but cannot support other sensor protocols. The same is true for the above four interfaces. The TAMAGAWA interface can only support the TAMAGAWA interface data transmission protocol, and the Biss interface can only support the Biss interface. Data transmission protocol, SSI interface can only support SSI interface data transmission protocol, EnDat interface can only support EnDat interface data transmission protocol, these position sensor interfaces greatly increase the difficulty of on-site debugging for technicians, and have strong limitations in practicability sex

Embodiment 1

[0047] Figure 4 It is a schematic diagram of the structure of the servo control system of the position sensor interface that supports multiple sensor communication protocols in the present invention. The system includes: CPU module, FPGA module, 485 chip and position sensor interface, wherein the CPU module is connected with the FPGA module, and the FPGA module They are respectively connected with two 485 chips, and the position sensor is connected with two 485 chips respectively. Among them, the CPU module is only used to read and write the position sensor data and other information cached in the FPGA module. The CPU module is mainly used for specific applications after reading the position sensor data, such as applications such as motion control. The CPU module accesses the FPGA module through the data, address, and read-write control bus; the FPGA module plays a central role in this method, not only realizing the function of automatically identifying various position senso...

Description

technical field [0001] The invention relates to the technical field of servo control, in particular to a method for implementing a position sensor interface supporting multiple sensor communication protocols. Background technique [0002] The large-scale production of modern manufacturing industry puts forward the requirements of high speed, high precision and high efficiency for processing equipment, and full digitalization is the inevitable trend of the development of servo drive technology. Full digitization includes: digitization of the internal control of the servo drive; digitization of the interface between the servo drive and the numerical control system; digitization of the measurement unit. The full digitalization of the internal position, speed, and current of the servo drive unit, the network control connection interface, and the digital connection interface from the encoder to the servo drive have become important symbols of full digitalization, such as figure ...
