西(xi)門子MM420變(bian)頻器代理商(shang)供(gong)應的西(xi)門子MM420變(bian)頻器主要由整流(liu)(liu)(liu)（交流(liu)(liu)(liu)變直(zhi)流(liu)(liu)(liu)）、濾波、再次整流(liu)(liu)(liu)（直(zhi)流(liu)(liu)(liu)變交流(liu)(liu)(liu)）、制動(dong)單元、驅動(dong)單元、檢測單元微(wei)處理單元等組成的。

西門子變頻器安裝調試方(fang)法(fa)如下：
i.西(xi)門子變頻器(qi)和電(dian)機的(de)距離應該(gai)盡量的(de)短，這(zhe)樣減小(xiao)了電(dian)纜(lan)的(de)對(dui)地電(dian)容(rong)，減少干擾的(de)發射(she)源。 
ii.控(kong)制電纜(lan)選用(yong)屏蔽(bi)(bi)電纜(lan)，動力電纜(lan)選用(yong)屏蔽(bi)(bi)電纜(lan)或者從西門(men)子變(bian)頻器(qi)到電機全部用(yong)穿(chuan)線管屏蔽(bi)(bi)。 
iii.電(dian)(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)(dian)纜(lan)(lan)應(ying)(ying)獨立于其它(ta)電(dian)(dian)(dian)(dian)纜(lan)(lan)走(zou)線，其小(xiao)距離為(wei)500mm。同時應(ying)(ying)避免電(dian)(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)(dian)纜(lan)(lan)與(yu)其它(ta)電(dian)(dian)(dian)(dian)纜(lan)(lan)長距離平行(xing)走(zou)線，這樣才能減少西門子變(bian)頻器輸出(chu)電(dian)(dian)(dian)(dian)壓快(kuai)速變(bian)化而產生(sheng)的電(dian)(dian)(dian)(dian)磁干擾。如果(guo)控(kong)制電(dian)(dian)(dian)(dian)纜(lan)(lan)和(he)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)纜(lan)(lan)交(jiao)叉，應(ying)(ying)盡可能使它(ta)們按90度角交(jiao)叉。與(yu)西門子變(bian)頻器有關的模擬量信號線與(yu)主(zhu)回路(lu)線分開走(zou)線，即(ji)使在控(kong)制柜中也要(yao)如此。 
iv.與西門子變(bian)頻器有關的(de)(de)模擬信號線好選用(yong)屏蔽雙(shuang)絞線，動力電(dian)纜(lan)(lan)選用(yong)屏蔽的(de)(de)三芯(xin)電(dian)纜(lan)(lan)(其規格要比(bi)普(pu)通電(dian)機的(de)(de)電(dian)纜(lan)(lan)大檔)或遵從西門子變(bian)頻器的(de)(de)用(yong)戶手冊。
