摘要
在分析了传统提升机的局限性的基础上,采用PLC为主控制器,实现对提升机的变频调速控制。介绍了控制系统的组成和工作过程,绘制了程序流程图,给出了编程思路。经过合理的硬件及软件设计,实现了提升机的无级平滑调速,停位准确。
On the basis of analyzing the limitations of traditional frequency control of motor speed control of the hoist is working process of the control system, draw the procedure reasonable hardware and software design, the stepless realized. elevator, PLC as the main controller, the This paper introduces the composition and flow chart, the programming thought is given. Through smooth speed regulation hoist is realized, parking isaccurate,
