The graduation project in order to satisfy the need of VFD Manufacturer that Control the position precision of ShanWang which is placed on the Glass foundation plate that is printed with electrode and phosphor. Devotes in designing a set of ShanWang movement control system which is low cost, high performance-to-price ratio, complete function and can be used in actual plant production.
This system selects Panasonic’s FPX PLC for its master unit because of its strong anti-jamming capability, rich flexible instructions, flexible extension and strong communication networking capability. In order to enhance the security and operability of the system, selects programmable terminal GT32 as auxiliary equipment of monitoring system. Through PLC switch quantity outputs control the periphery switch quantity equipments of PLC, using pulse outputs control the movement of servo motor in order to achieve the goal of position control and speed control. At the same time, using touch screen technology can realize the functions of parameter establishment, hand control real-time monitoring and so on.
