| Abstract: | For the demands of network and integration used in motion control,the article proposed a design program of network motion control chip based on FPGA.The design integrated the control of Ethernet chip,the analyse of network data protocol,a fine interpolator and the interface to the response of encoder into one single FPGA.In cooperation with the PC and the master of network,the network motion control chip can drive stepper motors or control servo drives used in position mode to realize highly efficient and integrate motion control.Simulation and machining results proved the feasibility of this design.The chip can be widely applied in such areas as CNC machine,motion control and so on. |
