Design of motion controller based on PC104

Aiming at that motion controller based PC can not meet the requirements for formidable conditions in practical industrial application in general,motion controller based on the PC104 embedded board and MCX314 motion control chip was designed.The function modules of the motion controller,interface between the PC104 bus and MCX314 chip I/O interface,the software modules and the interpolation module of the control system were introduced in detail.Three axis simultaneous motion linear interpolation and two axis simultaneous circle interpolation were realized with the controller.The designed controller was applied in the developed flame cutting machine,the practice shows that the excellent working performance is achieved in bad industrial application.
