Abstract：This paper aims at the cause analysis and rectification measures for the lack of over-current protection of the frequency converter under the half load state caused by the motor bearing fault. Through the technical transformation, it can avoid the further expansion of the motor and the driving equipment fault, which has a wide promotion significance in the motor driving equipment management industry.
