模擬量信號連接應(yīng)注意的問題變頻器中的模擬量輸入信號，通常指0～10V/5V 的電壓信號或0/4～20 ｍＡ的電流信號；這些模擬量輸入信號可通過接線端子由外部給定，當(dāng)變頻器與P L C 連接時(shí)，這些模擬量輸入信號也可來自PLC 的模擬量輸出信號，如圖3 所示。在進(jìn)行模擬量的連接時(shí)應(yīng)注意：

（1）阻抗匹配。根據(jù)變頻器的輸入阻抗選擇P L C 的輸出模塊，實(shí)現(xiàn)兩者的阻抗匹配。

（2）電壓范圍。當(dāng)變頻器和P L C 的電壓信號范圍不同時(shí)（如變頻器的輸入信號為0～10V，而PLC 的輸出電壓信號范圍為0～5V 時(shí)；或PLC 的一側(cè)的輸出信號電壓范圍為0～10V而變頻器的輸入電壓信號范圍為0～5V時(shí)），需采用串聯(lián)電阻的方式進(jìn)行分壓，以保證兩者在正常電壓范圍內(nèi)

工作，避免電壓過限可能損壞器件。

（3）采用屏蔽電纜或絞合電纜。對于變頻器和P L C 而言，弱電控制信號（電壓0～5V/10V、電流0/4～20ｍＡ等）易受到外界強(qiáng)信號的干擾，對控制信號采取適當(dāng)?shù)钠帘未胧?。常用的方式就是采用屏蔽電纜進(jìn)行屏蔽；對于長距離的控制回路宜采用絞合電纜，絞合電纜的絞合間距盡可能小。

（4）主、控電纜分開布線。實(shí)際連線時(shí)，注意主、控電纜分開布線，且相隔的距離。以保證主電路側(cè)的干擾及噪音影響不到控制電路。
