淺析引起LS伺服驅動器過電壓故障的原因及解決辦法:
一種相對常見的毛病是過電壓，一般顯現為“0V”或“OU”或相似現象，而且一般隨同呈現“DCLinkOvervoltage”的描繪。此故障問題是因為驅動器的內部DC總(zong)線(xian)看(kan)到(dao)的(de)電(dian)壓(ya)高(gao)於(yu)驅(qu)動(dong)器(qi)設(she)置(zhi)中(zhong)指(zhi)定(ding)的(de)約(yue)束(shu)。在(zai)大(da)都(dou)情(qing)況(kuang)下(xia)，當(dang)驅(qu)動(dong)器(qi)企(qi)圖(tu)使(shi)高(gao)慣(guan)性(xing)負(fu)載(zai)快(kuai)速(su)減(jian)速(su)時(shi)，就(jiu)會(hui)發(fa)生(sheng)此(ci)問(wen)題(ti)。然(ran)後(hou)，電(dian)動(dong)時(shi)機(ji)遭(zao)到(dao)負(fu)載(zai)的(de)檢(jian)修(xiu)，實(shi)踐(jian)上(shang)變(bian)成(cheng)了(le)發(fa)電(dian)機(ji)，將(jiang)電(dian)流(liu)推(tui)回(hui)到(dao)驅(qu)動(dong)器(qi)中(zhong)，並(bing)在(zai)直(zhi)流(liu)母(mu)線(xian)電(dian)壓(ya)有(you)時(shi)間(jian)泄(xie)放(fang)之(zhi)前(qian)為(wei)直(zhi)流(liu)電(dian)容(rong)器(qi)充(chong)電(dian)。然(ran)後(hou)，生(sheng)成(cheng)的(de)電(dian)壓(ya)會(hui)加(jia)到(dao)現(xian)有(you)的(de)總(zong)線(xian)電(dian)壓(ya)上(shang)，然(ran)後(hou)導(dao)致(zhi)過(guo)電(dian)壓(ya)。LS伺服驅動器具ju有you用yong戶hu可ke選xuan的de設she置zhi，旨zhi在zai減jian少shao在zai快kuai速su減jian速su或huo負fu載zai快kuai速su改gai變bian的de情qing況kuang下xia發fa生sheng此ci故gu障zhang的de可ke能neng性xing。還hai能neng夠gou手shou動dong調tiao整zheng加jia快kuai和he減jian速su參can數shu，以yi微wei調tiao斜xie坡po曲qu線xian，並bing在zai需xu求qiu時shi增zeng加jia時shi間jian以yi“軟化”發動和停止並防止過電壓。
除了這些根據軟件的辦法之外，還有其他辦法能夠處理由大修負載引起的過電壓毛病。LS伺服驅動器能(neng)夠(gou)在(zai)內(nei)部(bu)或(huo)外(wai)部(bu)包(bao)括(kuo)動(dong)態(tai)製(zhi)動(dong)電(dian)路(lu)。製(zhi)動(dong)電(dian)路(lu)有(you)時(shi)也(ye)稱(cheng)為(wei)製(zhi)動(dong)斬(zhan)波(bo)器(qi)，本(ben)質(zhi)上(shang)是(shi)一(yi)個(ge)開(kai)關(guan)，該(gai)開(kai)關(guan)呼(hu)應(ying)於(yu)直(zhi)流(liu)母(mu)線(xian)電(dian)壓(ya)超(chao)額(e)定(ding)值(zhi)的(de)快(kuai)速(su)上(shang)升(sheng)而(er)閉(bi)合(he)。然(ran)後(hou)，剩(sheng)餘(yu)的(de)電(dian)壓(ya)作(zuo)為(wei)熱(re)量(liang)經(jing)過(guo)大(da)電(dian)阻(zu)漏(lou)出(chu)。在(zai)非(fei)常(chang)小(xiao)的(de)驅(qu)動(dong)器(qi)中(zhong)，此(ci)電(dian)路(lu)是(shi)內(nei)部(bu)電(dian)路(lu)，而(er)在(zai)中(zhong)型(xing)和(he)較(jiao)大(da)的(de)驅(qu)動(dong)器(qi)中(zhong)，則(ze)采(cai)用(yong)獨(du)自(zi)的(de)製(zhi)動(dong)模(mo)塊(kuai)和(he)電(dian)阻(zu)櫃(gui)的(de)形(xing)式(shi)。製(zhi)動(dong)電(dian)路(lu)非(fei)常(chang)迅(xun)速(su)地(di)呼(hu)應(ying)後(hou)饋(kui)電(dian)壓(ya)，以(yi)維(wei)護(hu)直(zhi)流(liu)母(mu)線(xian)。可(ke)是(shi)，發(fa)生(sheng)的(de)高(gao)熱(re)量(liang)意(yi)味(wei)著(zhe)整(zheng)個(ge)體(ti)係(xi)功(gong)率(lv)的(de)損(sun)失(shi)。即(ji)便(bian)製(zhi)動(dong)占(zhan)空(kong)比(bi)一(yi)般(ban)很(hen)低(di)，正(zheng)確(que)選(xuan)擇(ze)電(dian)阻(zu)的(de)大(da)小(xiao)關(guan)於(yu)確(que)保(bao)電(dian)路(lu)持(chi)久(jiu)而(er)且(qie)將(jiang)損(sun)耗(hao)保(bao)持(chi)在(zai)盡(jin)可(ke)能(neng)低(di)的(de)水(shui)平(ping)。
