【Abstract】 One kind of design method for CNC interface based on PROFIBUS structure is discussed in this paper. The interface designed will improve the system performance which will be influenced by the analog command from the CNC to the servo system. The data construction based on the PROFIBUS for the CNC and the servo system is designed. The CNC interface given in this paper has many characteristics , such as far transfer distance, flexible structure ,high anti-jamming capability ,good extension ,easy being networked, and so on.更多还原
