User Manual of EM730/EM730E Series Inverter weakening current adjustment may cause instability. This does not need to be changed manually under normal circumstances. This parameter is used to determine the amplitude of the high-frequency current injected during the initial position identification. The larger this value, the higher the “squeak” sound will be.
