Overvoltage and UndervoltageEarth FaultOvercurrentThe 3 Most Common Faults on Inverters and How to Fix ThemOvervoltage This is caused by a high intermediate circuit DC voltage. This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter''s DC voltage. There are other causes of DC overvoltage, however. POSSIBLE FIXES: 1. Turn the overvoltage controller is on. 2. Check supply voltage for See more on inverterdrivesystems iee-business
