DRIVE AND DETECTION METHOD THEREOF

A detection method for a drive (1) is provided. Firstly, a step (S1) is performed to determine whether an operating parameter of the drive (1) is normal. If the determining condition of the step (S1) is satisfied, a step (S2) is performed to determine whether a value of the abnormal flag is 1. If the determining condition of the step (S2) is satisfied, the soft-start circuit is disabled. If the determining condition of the step (S1) or the step (S2) is not satisfied, the soft-start circuit (3) is enabled to turn on the switch (8) and then the capacitor (C) is pre-charged in a predetermined period. If a pre-charged voltage of the capacitor (C) is greater than a voltage threshold, the drive (1) enters a standby mode. If the pre-charged voltage of the capacitor (C) is not greater than the voltage threshold, the switch (8) is turned off.
