基于S7—200PLC与变频器(MM420)控制系统设计
摘要:PLC是在计算机技术、通信技术和继电器控制技术的发展基础上而开发出来的,现在已广泛应用于工业控制的各个领域.而且随着社会的发展,PLC与变频器密不可分,要完成好PLC与变频器控制系统的设计系统,除要求我们掌握必要的控制系统设计基础知识外,还要求我们必须经过反复实践,深入生产现场,将我们所学的理论知识和积累的经验技术应用到设计中来。本次课程设计正是本着这一目的而来进行PLC与变频器控制系统设计,通过这次课程设计,我感到更深地了解PLC与变频器控制系统的设计要求、设计内容和设计方法 。

Based on S7-200 PLC and frequency converter (MM420) control system design
Abstract: PLC is in the computer technology, communication technology and relay control technology, and developed on the basis of the development of now has been widely used in various fields of industrial control. And with the development of the society, the PLC and frequency converter are inseparable, good to complete the design of the control system of PLC and frequency converter system, in addition to the required us to master the necessary basic knowledge of control system design, also requires that we must go through repeated practice, in-depth production site, the theoretical knowledge and experience to what we have learned technology applied to the design. The curriculum design is in line with the purposes for PLC and inverter control system design, through this course design, I felt a deeper understanding of the PLC and frequency converter control system design requirements, design contents and design methods.
Key words: PLC, frequency converter, the control system
