2、 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。
