摘要
通过PLC通讯技术和触摸屏在轴承专用设备上的应用 ,阐述了如何利用PLC通过网络通讯技术控制变频器实现电机调速 ;介绍了使用触摸屏的一般方法。同时结合PLC与变频器进行通讯联络的实例 ,给出了较为详细的PLC梯形图。
By using the PLC communication technique and touch screen to special bearing equipment, how to utilize PLC to control frequency conversion to realize change speed of the motor is expatiated by net communication technique. The general method of using the touch screen is introduced. According to practical example which were communicated between PLC and frequency conversion made in Mitsubishi, the detail PLC echelon graphics has been given.
