4、 變頻器運(yùn)行時(shí)對(duì)PLC干擾應(yīng)注意的問題

變頻器運(yùn)行時(shí)會(huì)對(duì)周圍電氣設(shè)備（包括P L C ）產(chǎn)生較強(qiáng)的電磁干擾，同時(shí)變頻器主電路斷路器等開關(guān)器件動(dòng)作時(shí)也會(huì)影響PLC 的正常工作。為防止變頻器運(yùn)行時(shí)對(duì)PLC干擾，變頻器與P L C 相連接時(shí)應(yīng)該注意以下幾點(diǎn)：

（1）對(duì)PLC 本身應(yīng)按規(guī)定的接線標(biāo)準(zhǔn)和接地條件進(jìn)行接地，而且應(yīng)注意避免和變頻器使用共同的接地線，且在接地時(shí)使二者盡可能分開。

（2）當(dāng)電源電壓波動(dòng)大，諧波成分多時(shí)，為抑制諧波干擾，應(yīng)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(yán)重，應(yīng)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(shí)，應(yīng)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(qiáng)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(hào)連接、模擬量信號(hào)連接以及避免干擾應(yīng)注意的問題；在實(shí)際應(yīng)用中，兩者間的連接還涉及到用弱電信號(hào)控制強(qiáng)電的問題。因此，應(yīng)引起重視，避免干擾造成變頻器、PLC 的誤動(dòng)作；避免連接不當(dāng)造成PLC 或變頻器的損壞。

如果購買單位的在質(zhì)保日期一年內(nèi)發(fā)現(xiàn)有質(zhì)量缺陷的，可以進(jìn)行一個(gè)免費(fèi)維修或更換。
