三菱FX PLC在高壓變頻器中的應用
PLC主要邏輯控制
（1）用戶要求高壓變頻器在出現故障停機時能快速自動切換到工頻旁路運行，筆者給高壓變頻器專門配置了可以實現自動旁路功能的旁路柜，如圖1所示，K1～K4為手動操作刀閘，J1～J3為高壓真空接觸器。在變頻器發生故障時，旁路柜可以在幾秒內完成從變頻到工頻的轉換;而變頻器在工頻運行時，通過1個按鈕就可以實現變頻器從工頻到變頻的轉換。這樣的控制要求增加了變頻器整機控制邏輯的復雜性。
圖1 自動旁路柜
自動旁路柜控制邏輯簡要介紹如下：
變頻調速系統退出變頻轉工頻運行有兩種方式，一種是自動方式，一種是手動方式，選擇自動方式時，當變頻器發生停機故障時變頻器自動從變頻轉工頻;選擇手動方式時則需人工操作。
變頻調速系統退出工頻轉變頻運行也有兩種方式，一種是自動方式，一種是手動方式，選擇自動方式時，只需在控制柜上按一個按鈕，變頻器就自動完成從工頻轉變頻;選擇手動方式時則需人工操作.
（2）PLC控制系統原理圖
PLC主機選用輸入輸出點數48點，型號為FX2N-48MR，PLC作為系統邏輯量控制的控制核心，在自動旁路柜的邏輯關系控制中起著至關重要的作用。PLC控制系統原理圖如圖2所示。
