Thermal overload of brake coil or brake coil defective / connected incorrectly
SEW Eurodrive · MOVIFIT-FC Inverter
What does 89 mean?
The brake coil has experienced thermal overload, is defective, or is connected incorrectly. This can be triggered by a ramp time set too short, an issue identified during brake inspection, or an incorrect combination of the drive (brake coil) and MOVIFIT®-FC frequency inverter. It indicates a problem with the braking system's integrity or control.
