數字量信號連接應注意的問題
變頻器的輸入信號中包括對運行/ 停止、正轉/ 反轉、點動等運行狀態進行操作的數字量輸入信號（開關型指令信號），這些信號常來自PLC 的數字量輸出信號。PLC 通常利用其內部的繼電器接點（繼電器輸出型P L C ）或具有開關特性的元器件（晶體管輸出型PLC）與變頻器相連，得到運行狀態指令，如圖1 和圖2 所示。在進行數字量信號的連接時應注意：
（1）使用繼電器輸出型P L C 與變頻器相連時，應注意接觸不良常帶來變頻器誤動作，因此在實際接線中要注意連接可靠。
（2）使用晶體管輸出型P L C 與變頻器相連時，應注意晶體管本身的電壓的高低、電流的大小等限制條件在其範圍內，保證係統的可靠性。
（3）設計變頻器的輸入信號電路時，應盡量避免採用繼電器等感性負載，因繼電器開閉產生的浪涌電流可能引起變頻器的誤動作。
（4）當P L C 輸出的開關信號進入變頻器時，有時會發生外部電源和變頻器控制電源之間的串擾，應注意對P L C和變頻器分開接地，避免兩者使用共同的接地線。
