包括和應(yīng)用。
(1):
ABB Master Piece200單元是一高性能32位微處理器。存儲在EPROM模塊中,包括一個實時操作和一個ABB Master Piece語言(AMPL)執(zhí)行器。
(2)應(yīng)用
應(yīng)用存儲在帶后備電池的RWM(讀/寫存儲器)中,用ABB Master Piece語言(AMPL)編制,實現(xiàn)了結(jié)構(gòu)化程序設(shè)計。工業(yè)控制程序往往功能繁多該語言根據(jù)工業(yè)控制要求,將編程元素設(shè)計成一個個圖形功能塊,稱為PC元素。PC元素內(nèi)有三種結(jié)構(gòu)類元素GM、CONTRM和FUNCM,GM是程序結(jié)構(gòu)的高層,旨在完成一個完整的控制功能,一個GM下允許一個或幾個CONTRM,而一個CONTRM下又可包含一個或幾個FUNCM,從而使整個程序結(jié)構(gòu)呈階梯狀,實現(xiàn)了結(jié)構(gòu)化設(shè)計。
另外,在CPU內(nèi)還有一個實時數(shù)據(jù)庫,它的作用是存儲數(shù)據(jù)和在程序間傳遞數(shù)據(jù)。數(shù)據(jù)庫內(nèi)的元素稱為DB元素,這些元素包括站所使用的的I/O模板和及程序中產(chǎn)生的其它數(shù)據(jù)信息。

額定功率
額定功率是指在滿載運行時三相電動機(jī)軸上所輸出的額定機(jī)械功率,用表示,以千瓦(kW)或瓦(W)為單位。
3.額定電壓
額定電壓是指接到電動機(jī)繞組上的線電壓,用UN表示。三相電動機(jī)要求所接的電源電壓值的變動一般不應(yīng)超過額定電壓的±5%。電壓過高,電動機(jī)容易燒毀;電壓過低,電動機(jī)難以啟動,即使啟動后電動機(jī)也可能帶不動負(fù)載,容易燒壞。
4.額定電流
額定電流是指三相電動機(jī)在額定電源電壓下,輸出額定功率時,流入定子繞組的線電流,用IN表示,以安(A)為單位。若超過額定電流過載運行,三相電動機(jī)就會過熱乃至燒毀。
三相異步電動機(jī)的額定功率與其他額定數(shù)據(jù)之間有如下關(guān)系式
式中 ——額定功率因數(shù)
——額定效率
5.額定
額定是指電動機(jī)所接的交流電源每秒鐘內(nèi)周期變化的,用fN表示。我國規(guī)定電源為50Hz。
6.額定轉(zhuǎn)速
額定轉(zhuǎn)速表示三相電動機(jī)在額定工作情況下運行時每分鐘的轉(zhuǎn)速,用nN表示,一般是略小于對應(yīng)的同步轉(zhuǎn)速n1。如n1=1 500r/min,則nN =1 440r/min。
7.絕緣等級
絕緣等級是指三相電動機(jī)所采用的絕緣材料的耐熱能力,它表明三相電動機(jī)允許的高工作溫度。三相電動機(jī)的絕緣等級和高允許溫度參見表8.1。
