變頻器運行時對PLC幹擾應注意的問題
變頻器運行時會對周圍電氣設備（包括P L C ）產生較強的電磁幹擾，同時變頻器主電路斷路器等開關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幹擾，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，為抑制諧波幹擾，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。如果幹擾仍嚴重，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 安裝在同一電控櫃時，應盡可能使與變頻器有關的電纜和與PLC 有關的電纜分開安裝，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 結束語
變頻器和P L C 間連接問題，涉及到數字量信號連接、模擬量信號連接以及避免幹擾應注意的問題；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，避免幹擾造成變頻器、PLC 的誤動作；避免連接不當造成PLC 或變頻器的損壞。
如果購買單位的在質保日期一年內發現有質量缺陷的，可以進行一個免費維修或更換。
