西門子S120驅動器報F31125電機問題修復分析,西門(men)子伺服器(qi)維修(xiu),西門(men)子控制器(qi)維修(xiu),西門(men)子變頻(pin)器(qi)維修(xiu)
檢查編碼器(qi)電纜的布(bu)線(xian)和屏蔽(bi)是(shi)否符合 EMC 準則。
- 檢測插塞連接。
- 更換編碼器或者(zhe)編碼器電(dian)纜。
- 檢(jian)查編(bian)碼器模塊(kuai)(例如(ru):觸點)。
伺服電(dian)機編碼器故障(zhang)及維修
(1)編(bian)(bian)碼(ma)(ma)器(qi)(qi)本(ben)身(shen)故障:是(shi)指編(bian)(bian)碼(ma)(ma)器(qi)(qi)本(ben)身(shen)元器(qi)(qi)件(jian)出現故障,導致其(qi)不能產生和輸(shu)出正確的(de)波形。這種情況下需更換編(bian)(bian)碼(ma)(ma)器(qi)(qi)或維修(xiu)其(qi)內部器(qi)(qi)件(jian)。
(2)編碼(ma)器連接(jie)電(dian)(dian)纜故障:這(zhe)種故障出現的(de)幾率 最高,維修中(zhong)經常遇(yu)到,應(ying)是優先考慮的(de)因(yin)素(su)。通常為編碼(ma)器電(dian)(dian)纜斷(duan)(duan)路(lu)、短路(lu)或(huo)接(jie)觸不良(liang),這(zhe)時(shi)(shi)需更換電(dian)(dian)纜或(huo)接(jie)頭。還應(ying)特別注意(yi)是否是由于電(dian)(dian)纜固定不緊,造成松動引起(qi)開焊或(huo)斷(duan)(duan)路(lu),這(zhe)時(shi)(shi)需卡緊電(dian)(dian)纜。
(3)編碼(ma)器+5V電(dian)(dian)(dian)源下降:是指(zhi)+5V電(dian)(dian)(dian)源過低, 通常不能低于4.75V,造成過低的原因是供電(dian)(dian)(dian)電(dian)(dian)(dian)源故障或電(dian)(dian)(dian)源傳送電(dian)(dian)(dian)纜阻(zu)值偏大而引起(qi)損耗(hao),這時需檢(jian)修電(dian)(dian)(dian)源或更(geng)換電(dian)(dian)(dian)纜。
(4)絕對(dui)式(shi)編碼器電池(chi)電壓下(xia)降(jiang):這(zhe)種故障通(tong)常有含義明確(que)的(de)報警,這(zhe)時需更(geng)換電池(chi),如果參(can)考(kao)點位置記憶丟失,還須執(zhi)行重回參(can)考(kao)點操(cao)作。
(5)編碼器電纜屏蔽(bi)(bi)線未接或脫落:這會(hui)引入干擾信(xin)號,使(shi)波形(xing)不穩(wen)定,影響通信(xin)的準(zhun)確性,進口泵必須保證屏蔽(bi)(bi)線可靠的焊接及接地(di)。
(6)編碼器安裝松動:這種故(gu)障(zhang)會影響位置控制精(jing)度,造成停(ting)止和移(yi)動中位置偏差(cha)量超差(cha),甚至剛一開(kai)機即產生伺服系(xi)統(tong)過(guo)載(zai)報警,請(qing)特別注(zhu)意
(7)光柵污染:這會(hui)使(shi)信號輸出幅度下降,必(bi)須用脫脂棉(mian)沾*輕(qing)輕(qing)擦除油污。
