控制系統(tǒng)電路
控制裝置選用西門子S7-200系列PLC CPU224XPCN,這種型號的PLC除了帶有輸入輸出點外。還有1個模擬量輸入點和1個模擬量輸出點,這一型號PLC所具有的模擬量模塊,能夠滿足控制伺服電機的需要。觸摸屏選用西門子觸摸屏,型號為TP177B。
具體控制方案如圖l所示,觸摸屏是人機對話接口,最初的指令信息要從這里輸入。輸入的信息通過通訊端口傳送到PLC。經(jīng)運算后,PLC輸出模擬量,并連接到伺服控制器的模擬量輸入端口。伺服控制器對接收到的模擬量進(jìn)行內(nèi)部運算,而后驅(qū)動伺服電機達(dá)到相應(yīng)的轉(zhuǎn)速。伺服電機通過測速元件將轉(zhuǎn)速信息反饋到伺服控制器,形成閉環(huán)系統(tǒng),實現(xiàn)轉(zhuǎn)速穩(wěn)定的效果。~~~~~~~~~~~~~~~~~~~~~~~~~~~~

圖1 控制方案
由表1可看出,輸入值和實際轉(zhuǎn)速相差甚遠(yuǎn),而唯一的辦法是通過運算將輸入值轉(zhuǎn)換成能對應(yīng)上實際轉(zhuǎn)速的整形數(shù)值。但是還要首先找到最高轉(zhuǎn)速和最低轉(zhuǎn)速對應(yīng)的數(shù)值。通過實驗發(fā)現(xiàn),對應(yīng)關(guān)系如表2所示
PLC的模擬量輸出和伺服電機轉(zhuǎn)速輸出都是線性的,可以根據(jù)表2的數(shù)據(jù)列出直線方程組,計算出輸入值和整形數(shù)值之間的關(guān)系。ABB ACH 500 DRIVE CAT#ACH501-015-4-00P2 3 PHASE USED
