、使用複位和再啟動功能：

，ruoxuanzeshunshitingdianhoujixuyunxinggongnengshi，buxuyaofuweicaozuo，fudianhounengzidongzaiqidong。youxiebianpinqiyou“工頻切換選用件”，使用這種選用件可使因瞬停等原因脫離變頻器的電機在複電時繼續運轉
，即作為瞬停再啟動裝置使用。

2、調低低電壓保護值：

對有些品牌的變頻器
，當電壓低到額定值的90%左(zuo)右(you)時(shi)即(ji)停(ting)機(ji)，造(zao)成(cheng)同(tong)一(yi)電(dian)源(yuan)係(xi)統(tong)中(zhong)有(you)些(xie)大(da)啟(qi)動(dong)電(dian)流(liu)負(fu)載(zai)啟(qi)動(dong)時(shi)，變(bian)頻(pin)器(qi)都(dou)停(ting)機(ji)，這(zhe)些(xie)生(sheng)產(chan)商(shang)對(dui)用(yong)戶(hu)極(ji)不(bu)負(fu)責(ze)任(ren)。為(wei)提(ti)高(gao)這(zhe)類(lei)變(bian)頻(pin)器(qi)抗(kang)電(dian)壓(ya)波(bo)動(dong)能(neng)力(li)，可(ke)以(yi)適(shi)當(dang)調(tiao)低(di)這(zhe)類(lei)變(bian)頻(pin)器(qi)低(di)電(dian)壓(ya)保(bao)護(hu)值(zhi)

3、使用兩台變頻器互為熱備用：

兩liang台tai變bian頻pin器qi供gong電dian電dian源yuan分fen別bie引yin自zi不bu同tong的de供gong電dian係xi統tong
，當dang一yi台tai變bian頻pin器qi由you於yu某mou種zhong原yuan因yin停ting止zhi運yun行xing後hou，另ling一yi台tai變bian頻pin器qi自zi動dong投tou入ru運yun行xing。為wei了le保bao證zheng切qie換huan成cheng功gong，使shi用yong這zhe種zhong切qie換huan方fang式shi時shi，應ying根gen據ju旋xuan轉zhuan中zhong電dian機ji的de殘can留liu電dian壓ya檢jian出chu其qi轉zhuan速su，使shi變bian頻pin器qi的de輸shu出chu頻pin率lv與yu其qi一yi致zhi，安an全quan地di將jiang電dian動dong機ji切qie換huan到dao另ling一yi台tai變bian頻pin器qi運yun行xing，否fou則ze新xin投tou入ru運yun行xing的de變bian頻pin器qi會hui因yin過guo電dian流liu而er停ting止zhi運yun行xing。

4、交流側安裝電抗器：

對於變頻器而言，交流側交流側安裝電抗器主要是為了解決電源電壓三相不平衡度超出規定範圍(如富士變頻器要求不平衡度≤3%)，此電抗器的安裝對提高變頻器抗電壓波動能力大有好處。

5、使用瞬停再啟動控製：
