PLC as a the traditional relay replacement products, widely used in all areas of industrial control. PLC software can be used to change control process, and small size, flexible assembly and programming is simple, strong antijamming capability and high reliability, especially suitable for harsh environments.With the development of power electronics technology and control technology, the AC frequency control has been widely used in the field of industrial motor drag。 programmable logic controller PLC as a new alternative relay control device, often used for field data collection and control equipment .This article describes the inverter speed control system based on PLC. Now the most widely used PLC and inverter together the main function of frequency control. First set to the given input to the PLC, PLC control inverter to control the motor via the inverter control algorithms mainly by the PLC and inverter to plete the implementation of the ponents of the inverter and the motor.Key words：Power electronics。Converter。 Frequency control。Ac machive目 錄1概述 12系統(tǒng)設(shè)計總體方案與功能分析 1 1 23 PLC和變頻器的型號選擇 3 PLC的選擇 3 54硬件設(shè)計 6 6 6 7 9 9 10 PLC的硬件接線 11 PLC與變頻器的連接 12 135安裝調(diào)試 146總結(jié) 14參考文獻 15致 謝 16附 錄 17
