當天修復解決西門子S120伺服控制器報F30005過載故障分析；

F30005 功率(lv)單元：I2t 過載

信息(xi)類(lei)別： 功率元器件故障 (5)

驅動(dong)對象： A_INF, B_INF, R_INF, S_INF, SERVO, SERVO_AC, SERVO_I_AC

組件： 功率(lv)部件傳(chuan)播： LOCAL

原因： 功率單元過載(zai)（r0036 = 100 %）。

- 不(bu)允許(xu)長(chang)時間超過(guo)功率(lv)單元的額定電流。

- 沒有保持(chi)允許(xu)的(de)工作周期。

故障值(zhi)（r0949，十進制）：

I2t [100 % = 16384].

處(chu)理： - 減小連續負載。

- 調整工作周期。

- 檢(jian)查電機和功率單元的額定電流。

故(gu)(gu)(gu)障(zhang)現象：變(bian)(bian)(bian)頻器(qi)(qi)(qi)在(zai)加(jia)(jia)速(su)(su)、減(jian)(jian)速(su)(su)或正(zheng)常運行時(shi)(shi)出現過(guo)電(dian)(dian)(dian)流(liu)(liu)跳(tiao)閘。首先應區分(fen)(fen)是(shi)(shi)(shi)由于負載(zai)原因(yin)，還是(shi)(shi)(shi)變(bian)(bian)(bian)頻器(qi)(qi)(qi)的(de)(de)(de)原因(yin)引(yin)起的(de)(de)(de)。如(ru)果是(shi)(shi)(shi)變(bian)(bian)(bian)頻器(qi)(qi)(qi)的(de)(de)(de)故(gu)(gu)(gu)障(zhang)，可通過(guo)歷史記錄查詢在(zai)跳(tiao)閘時(shi)(shi)的(de)(de)(de)電(dian)(dian)(dian)流(liu)(liu)，超(chao)過(guo)了變(bian)(bian)(bian)頻器(qi)(qi)(qi)的(de)(de)(de)額定(ding)電(dian)(dian)(dian)流(liu)(liu)或電(dian)(dian)(dian)子熱(re)繼電(dian)(dian)(dian)器(qi)(qi)(qi)的(de)(de)(de)設定(ding)值，而三(san)相(xiang)電(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)流(liu)(liu)是(shi)(shi)(shi)平衡的(de)(de)(de)，則(ze)應考(kao)慮是(shi)(shi)(shi)否(fou)有過(guo)載(zai)或突變(bian)(bian)(bian)，如(ru)電(dian)(dian)(dian)機(ji)堵(du)轉等。在(zai)負載(zai)慣性較大時(shi)(shi)，可適(shi)當延長加(jia)(jia)速(su)(su)時(shi)(shi)間，此過(guo)程對變(bian)(bian)(bian)頻器(qi)(qi)(qi)本身并無損壞。若跳(tiao)閘時(shi)(shi)的(de)(de)(de)電(dian)(dian)(dian)流(liu)(liu)，在(zai)變(bian)(bian)(bian)頻器(qi)(qi)(qi)的(de)(de)(de)額定(ding)電(dian)(dian)(dian)流(liu)(liu)或在(zai)電(dian)(dian)(dian)子熱(re)繼電(dian)(dian)(dian)器(qi)(qi)(qi)的(de)(de)(de)設定(ding)范(fan)圍內，可判斷是(shi)(shi)(shi)IPM模(mo)塊或相(xiang)關部(bu)(bu)分(fen)(fen)發生(sheng)故(gu)(gu)(gu)障(zhang)。首先可以(yi)通過(guo)測量變(bian)(bian)(bian)頻器(qi)(qi)(qi)的(de)(de)(de)主(zhu)回(hui)路輸出端(duan)子U、V、W， 分(fen)(fen)別與直(zhi)流(liu)(liu)側的(de)(de)(de)P、N端(duan)子之(zhi)間的(de)(de)(de)正(zheng)反向電(dian)(dian)(dian)阻，來判斷IPM模(mo)塊是(shi)(shi)(shi)否(fou)損壞。如(ru)模(mo)塊未損壞，則(ze)是(shi)(shi)(shi)驅(qu)動電(dian)(dian)(dian)路出了故(gu)(gu)(gu)障(zhang)。如(ru)果減(jian)(jian)速(su)(su)時(shi)(shi)IPM模(mo)塊過(guo)流(liu)(liu)或變(bian)(bian)(bian)頻器(qi)(qi)(qi)對地短(duan)路跳(tiao)閘，一般是(shi)(shi)(shi)逆變(bian)(bian)(bian)器(qi)(qi)(qi)的(de)(de)(de)上(shang)半橋的(de)(de)(de)模(mo)塊或其驅(qu)動電(dian)(dian)(dian)路故(gu)(gu)(gu)障(zhang)；而加(jia)(jia)速(su)(su)時(shi)(shi)IPM模(mo)塊過(guo)流(liu)(liu)，則(ze)是(shi)(shi)(shi)下半橋的(de)(de)(de)模(mo)塊或其驅(qu)動電(dian)(dian)(dian)路部(bu)(bu)分(fen)(fen)故(gu)(gu)(gu)障(zhang)，發生(sheng)這些故(gu)(gu)(gu)障(zhang)的(de)(de)(de)原因(yin)，多(duo)是(shi)(shi)(shi)由于外部(bu)(bu)灰塵(chen)進入變(bian)(bian)(bian)頻器(qi)(qi)(qi)內部(bu)(bu)或環境潮濕引(yin)起。
