DC link overvoltage

What does F-07 mean?

The DC link voltage within the inverter has risen above safe operating limits, triggering an immediate shutdown with inhibit. This is typically caused by excessive regenerative energy from the motor during deceleration, an issue with the braking resistor, or a ground fault. Persistent overvoltage can damage the inverter's power stage.
