PLC控制交流变频调速控制系统在电梯中的应用分析

摘要

With the development of economy, the electronic technology is more and more widely applied in various fields. In recent years, the application of ac frequency conversion speed regulating scope expands unceasingly, elevator PLC control the application of ac frequency control of motor speed control system is close to mature, the design of PLC also made new progress. Based on the PLC control of the elevator, and discusses PLC control ac frequency control of motor speed control system in the application of the elevator.%随着经济的发展，电子技术在各个领域的应用越来越广泛。近年来，交流变频调速的应用范围不断扩大，电梯中PLC控制交流变频调速控制系统的应用已接近成熟，PLC的设计也取得了新的成果。以PLC对电梯的控制为基础，探讨PLC控制交流变频调速控制系统在电梯中的应用。
