4、 變頻器運行時對PLC干擾應注意的問題

變頻器運行時會對周圍電氣設(shè)備（包括P L C ）產(chǎn)生較強的電磁干擾，同時變頻器主電路斷路器等開關(guān)器件動作時也會影響PLC 的正常工作。為防止變頻器運行時對PLC干擾，變頻器與P L C 相連接時應該注意以下幾點：

（1）對PLC 本身應按規(guī)定的接線標準和接地條件進行接地，而且應注意避免和變頻器使用共同的接地線，且在接地時使二者盡可能分開。

（2）當電源電壓波動大，諧波成分多時，為抑制諧波干擾，應在PLC 的電源模塊及輸入/ 輸出模塊的電源線上接入噪音濾波器或者隔離變壓器。如果干擾仍嚴重，應考慮在變頻器主回路中接入電抗器、變壓器和噪音濾波器等措施。

（3）變頻器和P L C 安裝在同一電控柜時，應盡可能使與變頻器有關(guān)的電纜和與PLC 有關(guān)的電纜分開安裝，尤其是連接變頻器的強電電纜與連接PLC 的弱電電纜更要分開安裝。

4 結(jié)束語

變頻器和P L C 間連接問題，涉及到數(shù)字量信號連接、模擬量信號連接以及避免干擾應注意的問題；在實際應用中，兩者間的連接還涉及到用弱電信號控制強電的問題。因此，應引起重視，避免干擾造成變頻器、PLC 的誤動作；避免連接不當造成PLC 或變頻器的損壞。
