Abstract

With the CANopen protocol,the upper control of digital servo was realized in the CNC system based on the FPGA,MCP2510,MCP2551 and IDM640-8EIA digital servo drive hardware.The data sending and receiving between master and slave were carried out with the PDO(process data objects)and SDO(service data objects) mode.During the compiling process,VHDL was the main program language,the application function of CANopen master stage can be realized in FPGA.The results show that the digital servo can drive the servo motor in agreement with the requirements from the upper control instructions and realize the CANopen communicates successfully.
