【摘要】 针对大型金相试样切割机的控制要求,采用OMRONCPM2APLC和NS10-V1触摸屏相结合的控制方式,为该型金相试样切割机设计了控制系统。控制系统以PLC为核心,触摸屏作人机交互界面,PLC用于完成数据处理和控制任务,触摸屏完成操作和显示功能。采用变频调速技术对驱动切割片的电机进行无级调速。采用细分式驱动技术控制X向、Y向、Z向的步进电机运动。更多还原

【Abstract】 Facing the control requirements for the Metallographic sample cutting machine,the control system of the cutting machine was designed by the method of combing OMRON CPM2A PLC with NS10-V1 touch panel in this paper. As far as the control system is concerned, the core of the control system is PLC ,the touch panel is used for the man-machine intercommunication interface , PLC dedicates itself to data processing and controlling, the functions of operation and display are finished by the touch panel. Frequency conversion timing technology is adopted to control the asynchronism motor of driver cuts to attain stepless timing .By making use of the electrical driver-by step, To control X、Y、and Z to three step motor.更多还原
