電梯控制系統(tǒng)構成
電梯控制系統(tǒng)主要由變頻調速主回路、輸入輸出單元以及 PLC 單元構成,用來完成對電梯曳引電機及開關門機的起動,加減速,停止,運行方向,樓層顯示,層站召喚,轎箱內操作,安全保護等指令信號進行管理和控制功能。
變頻調速主回路由三相交流輸入、變頻調速驅動、曳引機和制動單元構成,變頻器采用日本安川公司矢量控制電梯專用變頻器616G5,其具有良好的低速運行特性,適合在電梯控制系統(tǒng)中應用。

三相電源 R、S、T 經接線端子進入變頻器為其主回路和控制回路供電,輸出端 U、V、W 接電動機的快速繞組,外接制動單元減少了制動時間,加快制動過程。旋轉編碼器用來檢測電梯的運行速度和運行方向,變頻器將實際速度與變頻器內部的給定速度相比較,從而調節(jié)變頻器的輸出頻率及電壓,使電梯的實際速度跟隨變頻器內部的給定速度,達到調節(jié)電梯速度的目的。變頻器輸入信號為:上、下行方向指令,零速、爬行、低速、高速、檢修速度等各種速度編碼指令,復位和使能信號。變頻器輸出信號為:(1)變頻器準備就緒信號,在變頻器運轉正常時,通知控制系統(tǒng)變頻器可以正常運行;(2)運行中信號,通知 PLC 變頻器正在正常輸出;(3)零速信號,當電梯運行速度為零時,此信號輸出有效并通知 PLC 完成抱閘、停車等動作;(4)故障信號,變頻器出現故障時,此信號輸出有效并通知 PLC 作出響應,給變頻器斷電。
