Cause : 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 braking cycle meets allowed limits.
