    Bus line adjustment caused a high-voltage fault

    Solution: This issue of drive overvoltage fault due to utility capacitor switching can be prevented by adding a line reactor or a DC choke to the drive. Because it's so common, some newer drives try to assist with locating the issue by providing more information about what the drive was doing. My SRT 5kxli had a issue in which dc bus over voltage is occurred in logs and load dropped. Kindly tell me the reason and solution. The high magnitude fault currents require high-speed. The power supply has voltage instability: If incoming line voltage fluctuates or spikes, it can push the DC bus beyond its design limits. There's a mismatch in load inertia: A high-inertia load that keeps spinning after the drive commands a stop will regenerate more power than the system can. There i have a SURT10000XLI made on 2008. my UPS first fault was 'BATTERY CAPACITOR SOFT START ' after fixing the PFC (ic904 and ic903) and resistor that was near the ic and replacing the D921 and 922 my ups fault changed to """"""" DC BUS OVERVOTAGE FAULT """""" !!! Would you please please please. Drive (VFD) overvoltage protection for common low HP drives is based on the measured voltage on the DC bus of the unit and not the input AC voltage. Any and all events that could cause a jump in DC bus voltage could lead to a dc link.
