若在調(diào)度進(jìn)程中出現(xiàn)頻率不上升的情況，即調(diào)整頻率調(diào)度旋扭時(shí)，頻率不上升，輸出電流繼續(xù)增大，呈限速維護(hù)情況，直至過(guò)流維護(hù)，這或許是低頻賠償短少構(gòu)成，可調(diào)度主控板上的賠償電位器(老機(jī)型)或通過(guò)設(shè)定變頻器的參數(shù)“低頻賠償”(新機(jī)型)予以處理。調(diào)整時(shí)留心只需輸出電流下來(lái)，頻率能升上去即可，也不可調(diào)整過(guò)大，避免過(guò)賠償，在工作進(jìn)程中電流過(guò)大而使電機(jī)及變頻器超電流而不正常工作。
正常工作后，可根據(jù)工作電流對(duì)電機(jī)維護(hù)儀的參數(shù)從頭調(diào)整一下，以到達(dá)可靠維護(hù)又能正常工作的情況。
對(duì)電機(jī)的正回轉(zhuǎn)要供認(rèn)。根據(jù)閱歷，通常情況下，正轉(zhuǎn)比回轉(zhuǎn)電流大，井口的壓力指示高?；剞D(zhuǎn)通常壓力表指針不起。有的井上油慢，要等一段時(shí)間才華判定。
因?yàn)楸咀冾l柜還設(shè)有工頻備用，以便在變頻出疑問(wèn)時(shí)能暫時(shí)投入工頻，不耽擱出產(chǎn)的進(jìn)行，因而變頻正常后還應(yīng)試一下工頻工作，其正回轉(zhuǎn)也應(yīng)調(diào)試正常。正回轉(zhuǎn)調(diào)整時(shí)，變頻調(diào)輸出，工頻調(diào)輸入，即可使工變頻都正常工作。
調(diào)整完后，用變頻工作，正常后，發(fā)起電機(jī)維護(hù)儀，維護(hù)儀閃現(xiàn)正常后，旋開(kāi)“變頻發(fā)起”旋扭(投入電機(jī)維護(hù)儀維護(hù)，不旋開(kāi)不起作用)，柜子上的各種表面指示都正常，調(diào)試即結(jié)束。
