，歐陸 590直流調速器不能調速。
檢查剖析：經檢查 +10V 電壓基準電源為 2V 左右， -10V 電壓基準電源為 -7V 左右，檢查有一 IC 發熱很大，替換后 -10V 電源正常，但 +10V 電源為 +13V ，再測量此 IC 四周有 2 個貼片電阻燒斷，替換后± 10 電源正常，接上馬達試機調速運轉正常。
4、故障為開機顯現oxf003。
換另一(yi)好(hao)的面板(ban)(ban)毛(mao)病照舊,證明(ming)毛(mao)病在底(di)板(ban)(ban),所以拿(na)另一(yi)臺好(hao)機測(ce)底(di)板(ban)(ban)各測(ce)試點(dian)、電壓(ya)(ya),再與壞機比照,發現(xian)vp31、vp32兩點(dian)電壓(ya)(ya)反常(chang)。 查(cha)ic2、ic339外圍無(wu)元件(jian)反常(chang),換339后電壓(ya)(ya)正常(chang),開機不再顯(xian)現(xian)oxf003報警,運轉一(yi)切(qie)正常(chang)。
