 調(diào)速控制：主機(jī)、喂料機(jī)選用艾默生EV2000/EV1000系列變頻器進(jìn)行調(diào)速控制，獨(dú)特的磁通矢量控制技術(shù)，保證電機(jī)0.5HZ時(shí)180%的啟動(dòng)轉(zhuǎn)矩，并保證轉(zhuǎn)速精度在0.5%以內(nèi)?？稍谟|摸屏上任意修改轉(zhuǎn)速，通過模擬量輸出模塊轉(zhuǎn)換為0-10V模擬量信號(hào)給定至變頻器,實(shí)現(xiàn)主機(jī)、喂料機(jī)的精確速度給定。同時(shí)變頻器將電流、轉(zhuǎn)速等參數(shù)通過模擬量輸入模塊反饋給主PLC，并在觸摸屏上進(jìn)行顯示和進(jìn)行超限報(bào)警保護(hù)控制。 溶壓顯示：壓力傳感器輸出4-20mA模擬量信號(hào)，直接連接至PLC模擬量輸入接口，轉(zhuǎn)換成數(shù)字量后可顯示壓力值，并可在觸摸屏上設(shè)定報(bào)警值進(jìn)行超壓報(bào)警。  人機(jī)對(duì)話界面：選用10.4寸真彩觸摸屏，與PLC的COM0通訊口連接，采用MODBUS串行通訊協(xié)議進(jìn)行數(shù)據(jù)交換，可實(shí)時(shí)顯示系統(tǒng)運(yùn)行狀態(tài)，對(duì)系統(tǒng)設(shè)備進(jìn)行控制操作，并可顯示系統(tǒng)運(yùn)行數(shù)據(jù)、報(bào)警內(nèi)容、修改工藝配方等。  互鎖和邏輯控制：EC10系列PLC程序容量可達(dá)12K步，指令處理速度0.3us，能夠根據(jù)系統(tǒng)工藝要求編寫程序?qū)崿F(xiàn)完美的邏輯控制。 
    控制系統(tǒng)特點(diǎn) 1、內(nèi)置兩個(gè)串行通訊口，可同時(shí)與觸摸屏以及其它外部設(shè)備進(jìn)行通訊。 2、 主PLC內(nèi)置模擬量輸入輸出，性價(jià)比高。 3、 系統(tǒng)最大可擴(kuò)展至128路開關(guān)量和19路模擬量，擴(kuò)展性好。 4、 超大的數(shù)據(jù)容量，可存儲(chǔ)多組配方參數(shù)及其它生產(chǎn)參數(shù)。 五、應(yīng)用總結(jié) 南京某高聚物裝備公司是專業(yè)從事雙螺桿塑料擠出造粒設(shè)備研發(fā)、生產(chǎn)和銷售的公司，其控制系統(tǒng)廣泛采用艾默生EC10系列PLC,具有很高的性價(jià)比，且穩(wěn)定可靠，深受客戶的好評(píng)。
