Cause : Brake resistor over temperature comes when the th.br trip is initiated if the hardware based braking resistor thermal monitoring is connected and the resistor overheats.
- If the braking resistor is not used, then this trip must be disabled with bit 3 of Action On Trip Detection (10.037) to prevent this trip.
- Check brake resistor wiring.
- Check braking resistor value is greater than or equal to the minimum resistance value.
- Check braking resistor insulation.
