模擬量信號連接應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，當變頻器與P L C 連接時，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。在進行模擬量的連接時應注意：
（1）阻抗匹配。根據變頻器的輸入阻抗選擇P L C 的輸出模塊，實現兩者的阻抗匹配。
（2）電壓範圍。當變頻器和P L C 的電壓信號範圍不同時（如變頻器的輸入信號為0∼10V，而PLC 的輸出電壓信號範圍為0∼5V 時；或PLC 的一側的輸出信號電壓範圍為0∼10V而變頻器的輸入電壓信號範圍為0∼5V時），需採用串聯電阻的方式進行分壓，以保證兩者在正常電壓範圍內
工作，避免電壓過限可能損壞器件。
（3）採用屏蔽電纜或絞合電纜。對於變頻器和P L C 而言，弱電控制信號（電壓0∼5V/10V、電流0/4∼20ｍＡ等）易受到外界強信號的幹擾，對控制信號採取適當的屏蔽措施。常用的方式就是採用屏蔽電纜進行屏蔽；對於長距離的控制回路宜採用絞合電纜，絞合電纜的絞合間距盡可能小。
（4）主、控電纜分開布線。實際連線時，注意主、控電纜分開布線，且相隔的距離。以保證主電路側的幹擾及噪音影響不到控制電路。
