摘　　要：为了提高步进驱动系统手动定位调节时的便利性,文中给出了一种采用手摇脉冲发生器(手轮)进行运动定位控制的系统。具体应用西门子S7 1200 PLC直接采集手轮转动时的A/B相脉冲频率,经程序处理后控制步进电机驱动十字工作台进行正反向移动定位。应用实践表明:系统具有开发成本低、可靠性高、人机交互体验感强等特点,其思路新颖、值得推广。In order to improve the convenience of manual positioning and adjustment of stepping drive system,a motion positioning control system using hand pulse generator(handwheel)is presented in this paper.Specifically,Siemens S71200 PLC is used to directly collect the A/B phase pulse frequency while the hand wheel is rotating.After the program is processed,the stepping motor is controlled to drive the cross table to move forward and backward for positioning.The application practice shows that the system has the characteristics of low development cost,high reliability and strong experience of human-computer interaction,and its idea is novel and worth popularizing.
