Overvoltage fault

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.

Complete Troubleshooting Guide

1. 1

   Increase the deceleration time parameter to allow the motor to slow down more gradually.

2. 2

   Implement a brake chopper and brake resistor, or use a dedicated Brake chopper unit to dissipate regenerative energy.

3. 3

   Verify the input voltage to the drive for high overvoltage spikes or unstable supply.
