若在调度进程中出现频率不上升的情况，即调整频率调度旋扭时，频率不上升，输出电流继续增大，呈限速维护情况，直至过流维护，这或许是低频赔偿短少构成，可调度主控板上的赔偿电位器(老机型)或通过设定变频器的参数“低频赔偿”(新机型)予以处理。调整时留心只需输出电流下来，频率能升上去即可，也不可调整过大，避免过赔偿，在工作进程中电流过大而使电机及变频器超电流而不正常工作。


正常工作后，可根据工作电流对电机维护仪的参数从头调整一下，以到达可靠维护又能正常工作的情况。
对电机的正回转要供认。根据阅历，通常情况下，正转比回转电流大，井口的压力指示高。回转通常压力表指针不起。有的井上油慢，要等一段时间才华判定。
因为本变频柜还设有工频备用，以便在变频出疑问时能暂时投入工频，不耽搁出产的进行，因而变频正常后还应试一下工频工作，其正回转也应调试正常。正回转调整时，变频调输出，工频调输入，即可使工变频都正常工作。
调整完后，用变频工作，正常后，发起电机维护仪，维护仪闪现正常后，旋开“变频发起”旋扭(投入电机维护仪维护，不旋开不起作用)，柜子上的各种表面指示都正常，调试即结束。
