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,使電氣傳動領(lǐng)域發(fā)生了一場技術(shù)革命,即交流調(diào)速取代直流調(diào)速,變頻調(diào)速被公認為有發(fā)展前途的調(diào)速方式。
可編程序控制器簡稱PLC(Programmable Logic Controller),它是一種數(shù)字運算與操作的控制裝置,廣泛應(yīng)用于工業(yè)控制的各個領(lǐng)域。PLC 通過軟件編程和硬件連接可實現(xiàn)復(fù)雜的控制任務(wù),控制功能強大,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)字量輸出信號與變頻器的數(shù)字量輸入信號相連;PLC 的模擬量輸出信號與變頻器的模擬量輸入信號相連。實際應(yīng)用中,就兩者正確連接時應(yīng)注意問題總結(jié)如下。同時,變頻器運行時會對周圍電氣設(shè)備產(chǎn)生較強的電磁干擾,為防止變頻器運行時對PLC 干擾,兩者相連接時應(yīng)重點考慮的問題總結(jié)如下。
