Cause : Brake resistor temperature has exceeded fault limit defined by parameter 48.06 Br temp fault limit.
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings (parameters
48.01...48.05).
Check fault limit setting, parameter 48.06
Br temp faultlim.
Check that braking cycle meets allowed
limits.
