The elevator as a modern high-rise building the vertical transport, and is closely related to people's lives, as people raise their requirements, the lift has been the rapid development of its technology has developed to drag the PSA Frequency Control, the logic control Also by the PLC to replace the original relay control. Based on the realization of a PLC and inverter of conventional elevator control on the basis of the converter through the PLC chip and a reasonable choice and design, use of Yasukawa VS-616G5-speed converter can be prepared for the lift of the characteristics of the improved comfort, to provide Technical support. Greatly improving the control of the elevator, the elevator and to improve the operation of comfort, so that the lift reached a better control and operation results. And using a rotary encoder pulse a position feedback, and lift the precise control of displacement. PLC program designed to achieve through the floor count, for speed signal, to open the door of peace control of the digital control signals to replace Wells Road location detection devices, improving the reliability of the system accuracy of the peace. The system has advanced, reliable and economic characteristics. The elevator control system has run drivers and drivers operating without that manual and automatic features, and with that layer, called the Office for the election of the Commission to function. Set election with control features. Key words: Elevator; PLC; Frequency Control; modular; Encoders
