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。
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. Fre- quency 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.
