1、變換為可調(diào)電壓、可調(diào)頻率的交流電裝置。變頻器廣泛應(yīng)用于節(jié)能、自動(dòng)化系統(tǒng)及提高工藝水平和產(chǎn)品質(zhì)量等方面。變頻器的問世，使電氣傳動(dòng)領(lǐng)域發(fā)生了一場(chǎng)技術(shù)革命，即交流調(diào)速取代直流調(diào)速，變頻調(diào)速被公認(rèn)為有發(fā)展前途的調(diào)速方式。

    可編程序控制器簡(jiǎn)稱PLC（Programmable Logic Controller），它是一種數(shù)字運(yùn)算與操作的控制裝置，廣泛應(yīng)用于工業(yè)控制的各個(gè)領(lǐng)域。PLC 通過軟件編程和硬件連接可實(shí)現(xiàn)復(fù)雜的控制任務(wù)，控制功能強(qiáng)大，是當(dāng)代工業(yè)控制的三大支柱之一。作為工控產(chǎn)品，變頻器和PLC 常配合使用（PLC 作為編程器，變頻器作為驅(qū)動(dòng)器），完成控制任務(wù)。 

    P L C 與變頻器的連接主要方式有：PLC 的數(shù)字量輸出信號(hào)與變頻器的數(shù)字量輸入信號(hào)相連；PLC 的模擬量輸出信號(hào)與變頻器的模擬量輸入信號(hào)相連。實(shí)際應(yīng)用中，就兩者正確連接時(shí)應(yīng)注意問題總結(jié)如下。同時(shí)，變頻器運(yùn)行時(shí)會(huì)對(duì)周圍電氣設(shè)備產(chǎn)生較強(qiáng)的電磁干擾，為防止變頻器運(yùn)行時(shí)對(duì)PLC 干擾，兩者相連接時(shí)應(yīng)重點(diǎn)考慮的問題總結(jié)如下。
