Valco C22-6186PAT變頻調(diào)速系統(tǒng)
1)起升工況及要求
起升機(jī)構(gòu)要求較大的調(diào)速比和較硬的機(jī)械特性,以適應(yīng)重物的精確吊裝要求;要求有大的起動(dòng)轉(zhuǎn)矩,優(yōu)異的動(dòng)態(tài)轉(zhuǎn)矩響應(yīng)能力,以適應(yīng)負(fù)載突變,保證重載二次起升的能力;必須解決好再生制動(dòng)狀態(tài)的能量回饋與處理,以縮短減速停車時(shí)間;必須解決好溜鉤問題。
2)變頻功能應(yīng)用
根據(jù)起升機(jī)構(gòu)特性和技術(shù)要求,變頻器采用帶測(cè)速反饋接口的800系列變頻器,配合ACC 7.2提升軟件,形成閉環(huán)直接轉(zhuǎn)矩控制,通過預(yù)勵(lì)磁功能和啟動(dòng)轉(zhuǎn)矩設(shè)定,使電機(jī)啟動(dòng)瞬間力矩zui高可達(dá)300%,實(shí)現(xiàn)了優(yōu)異的啟動(dòng)特性.內(nèi)置制動(dòng)斬波器,外接制動(dòng)電阻,使制動(dòng)過程中的產(chǎn)生的再生能量通過制動(dòng)電阻得到釋放,達(dá)到快速制動(dòng)的目的。使用機(jī)械制動(dòng)控制功能,使電機(jī)轉(zhuǎn)矩釋放和制動(dòng)器緊密配合,更好地提高了設(shè)備的安全性,承受頻繁起動(dòng)沖擊的能力及可靠性也大為增加。
