Cause : BR excess temperature - comes when Brake resistor temperature has exceeded warning limit defined by parameter 43.12 Brake resistor warning limit.

  1. Stop drive. Let resistor cool down.
  2. Check resistor overload protection function settings (parameter group 43 Brake chopper).
  3. Check warning limit setting, parameter 43.12 Brake resistor warning limit.
  4. Check that the resistor has been dimensioned correctly.
  5. Check that braking cycle meets allowed limits.
