Servo-motor transmission control system for Low-E glass production line

A distribution system control method based on Siemens S7-400 PLC and SEW servo-motor was proposed,according to the characteristics of the Low-E glass production line transmission system.The system network architecture and the control strategy of the underlying servo motors were described,the model selection method of the servo motors and the calculation formula were discussed,and a typical servo controller program was presented.A single CPU for lower system control and two industrial PC for upper system management were used in the system.Through the close integration of WINCC and STEP7,the real-time monitoring and control for the transmission process were implemented.The production results show that the transmission system based on this strategy has the following features: complete structure,multiple functions,stable working and well performance.The system meets the requirements of magnetic control sputtering emission method and finally realizes the automatic production line running.
