Cause : BR excess temperature - comes when Brake resistor temperature has exceeded warning limit defined by parameter 43.12 Brake resistor warning limit.
- Stop drive. Let resistor cool down.
- Check resistor overload protection function settings (parameter group 43 Brake chopper).
- Check warning limit setting, parameter 43.12 Brake resistor warning limit.
- Check that the resistor has been dimensioned correctly.
- Check that braking cycle meets allowed limits.
