F2
Overvoltage fault
Vacon · NXP AFE-II Drive
What does F2 mean?
The DC-link voltage has surpassed the drive's protective limits (e.g., above 911 Vdc for a 500 Vac unit or 1200 Vdc for a 690 Vac unit). This can be a hardware trip or sustained overvoltage due to control supervision. Persistent overvoltage can damage power components and reduce drive lifespan.
Additional Steps
