西門子840D按鍵不靈/鼠標能用維修廠家,我(wo)公司是(shi)國內較早從事工控(kong)設備維修(xiu)(xiu)單位,是(shi)德國SIEMENS西(xi)門(men)子專業維修(xiu)(xiu)單位,目(mu)前擁(yong)有專業的(de)(de)維修(xiu)(xiu)工程師(shi)和*維修(xiu)(xiu)設備,具有豐富的(de)(de)維修(xiu)(xiu)技(ji)術(shu)和經驗。我(wo)們一(yi)直專注維修(xiu)(xiu)技(ji)術(shu)的(de)(de)研(yan)究,保(bao)證(zheng)不二次(ci)損壞(huai)機器,一(yi)般故障當(dang)天修(xiu)(xiu)好,不收取(qu)任何檢測費用,維修(xiu)(xiu)西(xi)門(men)子就找專修(xiu)(xiu)西(xi)門(men)子公司!
西門子840D按鍵不靈/鼠標能用維修廠家,檢(jian)查方法 對這種故障(zhang),應先檢(jian)查系統84D0本身是(shi)(shi)否異(yi)常(chang)、參數設置是(shi)(shi)否正(zheng)確、調速輸(shu)入(ru)信(xin)號是(shi)(shi)否 正(zheng)常(chang)。如(ru)均正(zheng)常(chang),且運(yun)行時測得變頻(pin)器直(zhi)流母線電(dian)(dian)壓(ya)只有約(yue)450V(正(zheng)常(chang)值(zhi)應為(wei)580~600V), 則這種故障(zhang)多(duo)(duo)是(shi)(shi)缺(que)相(xiang)(缺(que)一相(xiang))引起的,應檢(jian)查電(dian)(dian)路中的空氣開關接觸是(shi)(shi)否良(liang)好(hao)。 (2)故障(zhang)原因 變頻(pin)器輸(shu)入(ru)缺(que)相(xiang)不報(bao)警(jing)仍能在低頻(pin)段(duan)工作,是(shi)(shi)因為(wei)多(duo)(duo)數系統的母線電(dian)(dian)壓(ya)下限(xian)為(wei)400V, 而當母線電(dian)(dian)壓(ya)降至(zhi)400V以下時,變頻(pin)器才(cai)顯示直(zhi)流母線電(dian)(dian)壓(ya)低故障(zhang)。
當(dang)兩相(xiang)輸(shu)(shu)(shu)入時(shi),直 流(liu)線電(dian)壓(ya)為(wei) 大于400V。當(dang)變(bian)頻器(qi)不(bu)(bu)運行(xing)(xing)時(shi),由(you)于濾波電(dian)容器(qi)的作(zuo)(zuo)用(yong),直流(liu)電(dian)壓(ya)也(ye)可(ke)達到正(zheng)常值。新 型的變(bian)頻器(qi)都采(cai)用(yong)PWM(脈寬調(diao)制(zhi))控(kong)(kong)制(zhi)技術(shu),調(diao)壓(ya)調(diao)頻的工(gong)作(zuo)(zuo)在(zai)逆變(bian)橋完(wan)成,所以在(zai) 低(di)頻段輸(shu)(shu)(shu)入缺相(xiang)仍(reng)可(ke)以正(zheng)常工(gong)作(zuo)(zuo),但因輸(shu)(shu)(shu)入電(dian)壓(ya)、輸(shu)(shu)(shu)出電(dian)壓(ya)低(di),造成異步電(dian)動(dong)機轉矩低(di) 頻率上(shang)不(bu)(bu)去。變(bian)頻器(qi)的設定(ding)參(can)數(shu)(shu)較多,每(mei)個(ge)(ge)參(can)數(shu)(shu)均(jun)有(you)一定(ding)的選擇范圍,使用(yong)中常常遇到因個(ge)(ge)別參(can)數(shu)(shu)設置不(bu)(bu)當(dang),導致變(bian)頻器(qi)不(bu)(bu)能(neng)正(zheng)常工(gong)作(zuo)(zuo)的現(xian)象,因此,必須對相(xiang)關的參(can)數(shu)(shu)進(jin)行(xing)(xing)正(zheng)確的設定(ding),1、控(kong)(kong)制(zhi)方式:即速(su)(su)度控(kong)(kong)制(zhi)、轉距(ju)控(kong)(kong)制(zhi)、PID控(kong)(kong)制(zhi)或其(qi)他方式,采(cai)取控(kong)(kong)制(zhi)方式后,一般要根據控(kong)(kong)制(zhi)精度進(jin)行(xing)(xing)靜態或動(dong)態辨識,2、最低(di)運行(xing)(xing)頻率:即電(dian)機運行(xing)(xing)的最小轉速(su)(su),電(dian)機在(zai)低(di)轉速(su)(su)下(xia)運行(xing)(xing)時(shi),其(qi)散(san)熱性能(neng)很差,電(dian)機長時(shi)間運行(xing)(xing)在(zai)低(di)轉速(su)(su)下(xia),會(hui)導致電(dian)機燒(shao)毀(hui)
