驅動(dong)(dong)器的細分驅動(dong)(dong)設置(zhi)

什么是細(xi)分(fen)(fen)(fen)(fen)(fen)驅(qu)動(dong)(dong)(dong)(dong)(dong)？步進電(dian)機在(zai)出(chu)廠時都(dou)標注(zhu)了“固(gu)有步距(ju)角”。比如(ru)某電(dian)機的(de)(de)固(gu)有步距(ju)角為0.9度/1.8度，驅(qu)動(dong)(dong)(dong)(dong)(dong)器(qi)公司，表示電(dian)機半步工作每次會(hui)轉(zhuan)過0.9度，整步1.8度。在(zai)很多精(jing)密控(kong)制(zhi)的(de)(de)場合，固(gu)有步距(ju)角不能(neng)滿足(zu)控(kong)制(zhi)精(jing)度的(de)(de)要求(qiu)，人(ren)們希(xi)望能(neng)將一個固(gu)有步距(ju)角分(fen)(fen)(fen)(fen)(fen)很多步來走完。這(zhe)種將固(gu)有步距(ju)角再(zai)分(fen)(fen)(fen)(fen)(fen)成很多步的(de)(de)驅(qu)動(dong)(dong)(dong)(dong)(dong)方法，稱(cheng)為'細(xi)分(fen)(fen)(fen)(fen)(fen)驅(qu)動(dong)(dong)(dong)(dong)(dong)'。能(neng)實(shi)現細(xi)分(fen)(fen)(fen)(fen)(fen)驅(qu)動(dong)(dong)(dong)(dong)(dong)的(de)(de)驅(qu)動(dong)(dong)(dong)(dong)(dong)器(qi)，稱(cheng)為'細(xi)分(fen)(fen)(fen)(fen)(fen)驅(qu)動(dong)(dong)(dong)(dong)(dong)器(qi)'。

驅動器是什么？

驅(qu)(qu)動(dong)器(qi)(qi)（driver）從廣(guang)義(yi)上指的是驅(qu)(qu)動(dong)某類(lei)設備的驅(qu)(qu)動(dong)硬件。在計算機(ji)領域(yu)(yu)驅(qu)(qu)動(dong)器(qi)(qi)指的是磁(ci)盤(pan)驅(qu)(qu)動(dong)器(qi)(qi)。通(tong)過某個文(wen)件系(xi)統格式化并帶有一個驅(qu)(qu)動(dong)器(qi)(qi)號的存(cun)(cun)儲區域(yu)(yu)。存(cun)(cun)儲區域(yu)(yu)可以是軟(ruan)盤(pan)、CD、硬盤(pan)或其他(ta)類(lei)型(xing)的磁(ci)盤(pan)。單擊“Windows資源管理器(qi)(qi)”或“我的電腦”中相應(ying)的圖標(biao)可以查(cha)看驅(qu)(qu)動(dong)器(qi)(qi)的詳細內容。

驅動(dong)器(qi)在整個控(kong)(kong)制(zhi)(zhi)環(huan)節(jie)中(zhong)，驅動(dong)器(qi)價格，正好處于主控(kong)(kong)制(zhi)(zhi)箱（MAIN CONTROLLER）--》驅動(dong)器(qi)（DRIVER）--》馬達（MOTOR）的(de)中(zhong)間(jian)換節(jie)。驅動(dong)器(qi)的(de)主要功能是接收來(lai)自主控(kong)(kong)制(zhi)(zhi)箱（NC CARD）的(de)信號，河南驅動(dong)器(qi)，然后將信號進(jin)行處理再轉移至(zhi)馬達以(yi)及和(he)馬達有關(guan)的(de)感應器(qi)（SENSOR），并且(qie)將馬達的(de)工作情(qing)況反(fan)饋至(zhi)主控(kong)(kong)制(zhi)(zhi)箱（MAIN CONTROLLER）。

驅動器結構(gou)組成及作用(yong)

步進(jin)(jin)驅動(dong)器接收上位機(ji)的(de)脈沖(chong)(chong)信(xin)(xin)(xin)號(hao)(hao)，驅動(dong)器公司(si)，再分配脈沖(chong)(chong)信(xin)(xin)(xin)號(hao)(hao)，再把信(xin)(xin)(xin)號(hao)(hao)功率放(fang)大，再輸出(chu)給(gei)步進(jin)(jin)電動(dong)機(ji)繞組，使電動(dong)機(ji)轉動(dong)。由此可知(zhi)，步進(jin)(jin)驅動(dong)器一般由脈沖(chong)(chong)信(xin)(xin)(xin)號(hao)(hao)發(fa)生電路、脈沖(chong)(chong)分配電路和功率放(fang)大電路構(gou)成(cheng)。

1、脈沖發(fa)生器（變(bian)頻(pin)信(xin)號源）：將(jiang)產生的基準頻(pin)率信(xin)號輸入給脈沖分(fen)配器，由(you)上位機或多諧(xie)振蕩(dang)器和單結晶體(ti)管構成的弛張振蕩(dang)器電(dian)路來發(fa)送(song)脈沖。

2、脈(mo)沖(chong)分(fen)配器(qi)(qi)（環(huan)形分(fen)配器(qi)(qi)）：由(you)雙穩(wen)態觸發器(qi)(qi)和門電路組(zu)成，也可(ke)由(you)可(ke)編程邏輯器(qi)(qi)件組(zu)成，是(shi)一個數(shu)字邏輯單元，作用是(shi)根據運行(xing)指令(ling)按一定的(de)(de)邏輯關系分(fen)配脈(mo)沖(chong)信號(hao)到每一相(xiang)的(de)(de)脈(mo)沖(chong)放大器(qi)(qi)上。
