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PLC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PLC的輸出模塊,實現兩者的阻抗匹配。
(2)電壓範圍。當變頻器和PLC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PLC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。
