What does Stall prevention (overvoltage) mean?
The overvoltage stall prevention function has been activated, often during regeneration avoidance operation. This warning indicates that the DC bus voltage is exceeding safe limits, typically due to rapid deceleration or regenerative loads feeding energy back into the inverter. Sustained overvoltage can damage the inverter's internal components.
