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.

What is inverter overload? Overload occurs when the total power of connected loads exceeds the inverter''s rated output power (long-term limit) or peak power capacity (short-term surge

There are two main reasons for the inverter overvoltage: the inverter power supply overvoltage and the inverter regenerative overvoltage. The overvoltage of the power supply means

During overvoltage events, the main DC bus capacitor charges and stores energy, causing voltage to rise. When it approaches the capacitor''s rated value (typically ~800V), the inverter activates
