Is the vertical lift transport equipment, is an indispensable high-rise building transportation equipment. It relies on power, drag a person or thing can be contained in the car, in the construction of the shaft to do within the rail vertical movement in peoples lives plays an important role. The PLC to control elevator systems have become increasingly demanding, requiring elevator reached the steady, accurate, fast operational purposes. The system is composed of PLC, logic control circuit. Including AC induction motors, relays, contactors, trip switches, buttons, LED indicators and frequency composition as one of the control system. The machine control unit to Siemens PLC programmable controller controls the whole process of the machine. The entire system through the PLC, logic control circuit of the elevator lift; accelerating or decelerating; flat layer; starting and braking control. Its structure is simple, high efficiency, high precision leveling, easy to understand and grasp. Keywords: Drive system;Control system;PLC procedure 目录 第一章 绪
