As part of the open CNC systems important component, motion control card research and development has been given more and more importance. From the point of development trend, based on the CAN bus, CPLD and FPGA as the core processor of the open motion controller is becoming the mainstream. This kind of open motion controller with CPLD or FPGA chip as the core processor of motion controller,with PC as the information processing platform, motion controller in embedded PC plug-in card form, also is the use of PC+ motion controller mode,this model will be PC machine information processing ability and open characteristics and motion controller for trajectory control ability organically together, with information processing ability, high degree of opening, motion trajectory control accuracy, good versatility. The graduation project designs a CPLD control applied in motion control card design system, the system uses MAX IIEPM570T14 as the core.The purpose of the design was to output two paths of pulse waveform, one waveform lag another90 degrees, and can realize the output pulse frequency adjustable. In this design uses the MAX IIEPM570T144 as the controller, using Verilog HDL as a design language, using Quartus simulation software for frequency division module, frequency modulation module and lag module simulation was carried out ，thus control precision stepper motor running.
