Cause : BR excess temperature - comes when Brake resistor temperature has exceeded fault limit defined by parameter 43.11 Brake resistor fault limit.

1. Stop drive. Let resistor cool down.
2. Check resistor overload protection function settings (parameter group 43 Brake chopper).
3. Check fault limit setting, parameter 43.11 Brake resistor fault limit.
4. Check that braking cycle meets allowed limits.
