Cause : Braking resistor temperature has exceeded alarm limit defined by parameter 48.07 BR TEMP ALARM LIMIT.
Stop drive.
Let resistor cool down.
Check resistor overload protection function settings,
parameters 48.01...48.05.
Check alarm limit setting, parameter 48.07.
Check that braking cycle meets allowed limits.
