變頻器輸入信號中包括對運行/停止、正轉(zhuǎn)/反轉(zhuǎn)、微動等運行狀態(tài)進行操作開關(guān)型指令信號。變頻器通常利用繼電器接點或具有繼電器接點開關(guān)特性元器件(如晶體管)與PLC)相連,到運行狀態(tài)指令。
使用繼電器接點時,常常接觸不良而帶來誤動作;使用晶體管進行連接時,則需考慮晶體管本身電壓、電流容量等因素,系統(tǒng)可靠性。設(shè)計變頻器輸入信號電路時還應該注意,當輸入信號電路連接不當時也會造成變頻器誤動作。例如,當輸入信號電路采用繼電器等感性負載時,繼電器開閉產(chǎn)生浪涌電流帶來噪音有可能引起變頻器誤動作,應盡量避免。
變頻器中也存一些數(shù)值型(如頻率、電壓等)指令信號輸入,可分為數(shù)字輸入和模擬輸入兩種。數(shù)字輸入多采用變頻器面板上鍵盤操作和串行接口來給定;模擬輸入則接線端子由外部給定,通常0~10V/5V電壓信號或0/4~20mA電流信號輸入。接口電路因輸入信號而異,變頻器輸入阻抗選擇PLC輸出模塊。
