西門子數控系統一級代理--動能緩沖(Vdc min 控制)

6.29 動(dong)能緩沖(chong)(Vdc min 控(kong)制)

動能緩沖可以變頻器的可用性。在出現電壓驟降或電源掉電時,動能緩沖利用負載動能使設備繼續工作。電壓驟降期間,變頻器會盡可能使電機保持接通狀態。時間為一秒。

合理使用“動能緩沖"功(gong)能需(xu)遵循以下前提(ti)條件:

● 工作機(ji)械(xie)的回轉足夠大。

● 電機在電源掉電時能夠減速(su)制動。

Vdc_min 控制(zhi)僅(jin)適用于(yu)功率模塊 PM240?2 和 PM240P?2。

如果電壓驟降,變頻器中的直流母線電壓也會下降。達到設定的閾值后,動能緩沖(VDCmin 控制)介入。VDC min 控制迫使負載輕再生。為此,變頻器會用負載動能彌補其損耗功率及電機中的損耗。期間,負載轉速下降,但直流母線電壓保持恒定。電源恢復后, 變頻器立即再次正常。

公司(si)經營范(fan)圍包括(kuo)工(gong)業自動化(hua)設(she)(she)備(bei)(bei),電(dian)(dian)(dian)子(zi)元器件,儀(yi)器儀(yi)表(biao),電(dian)(dian)(dian)線電(dian)(dian)(dian)纜,通信設(she)(she)備(bei)(bei)及相關產(chan)品(pin),電(dian)(dian)(dian)器設(she)(she)備(bei)(bei),電(dian)(dian)(dian)氣設(she)(she)備(bei)(bei),五金交電(dian)(dian)(dian),電(dian)(dian)(dian)子(zi)設(she)(she)備(bei)(bei),機(ji)電(dian)(dian)(dian)設(she)(she)備(bei)(bei)及配(pei)件,機(ji)械(xie)設(she)(she)備(bei)(bei),電(dian)(dian)(dian)子(zi)產(chan)品(pin)銷售,機(ji)械(xie)設(she)(she)備(bei)(bei)安(an)裝維修,從事“工(gong)業自動化(hua)、電(dian)(dian)(dian)子(zi)”科技領域內技術開發(fa)、技術轉讓、技術咨詢(xun)、技術服務(wu)等

西門子6SE7O變頻柜的失速防止功能包括兩個方面(mian):

1、加(jia)(jia)速(su)(su)(su)中:(1)加(jia)(jia)速(su)(su)(su)時(shi)(shi)間若預置的(de)(de)過(guo)短(duan),容易因過(guo)電(dian)(dian)流(liu)而跳(tiao)閘。(2)加(jia)(jia)速(su)(su)(su)時(shi)(shi)間過(guo)長,又(you)會影響機臺運(yun)行效率。況且(qie),生(sheng)產機臺的(de)(de)工(gong)況也時(shi)(shi)有變(bian)化,這(zhe)給用(yong)戶在預置“加(jia)(jia)速(su)(su)(su)時(shi)(shi)間”時(shi)(shi)帶來了困難,難以(yi)迅(xun)速(su)(su)(su)地預置的(de)(de)恰(qia)到好處(chu)。變(bian)頻器在加(jia)(jia)速(su)(su)(su)中出現過(guo)電(dian)(dian)流(liu)時(shi)(shi),可(ke)以(yi)不必跳(tiao)閘,而啟(qi)動(dong)“防止跳(tiao)閘”程序。具體方法(fa)是:如果(guo)在加(jia)(jia)速(su)(su)(su)中,電(dian)(dian)流(liu)超過(guo)了預置的(de)(de)上限(xian)值,變(bian)頻器的(de)(de)輸出將不再,暫緩加(jia)(jia)速(su)(su)(su),待電(dian)(dian)流(liu)下(xia)降到上限(xian)值以(yi)下(xia)后再繼續加(jia)(jia)速(su)(su)(su)。

2、減速(su)(su)中(zhong):對于慣性較大的(de)負載,如果(guo)(guo)減速(su)(su)時間(jian)預置的(de)過(guo)短,會因拖動系統的(de)功能(neng)釋放(fang)得太快而(er)引起(qi)直流回路的(de)過(guo)電壓(ya)。如果(guo)(guo)在(zai)減速(su)(su)中(zhong),直流電壓(ya)超過(guo)了上限值(zhi),變頻器(qi)的(de)輸(shu)出不再下降,暫緩減速(su)(su),待直流電壓(ya)下降到設定值(zhi)。
