Cause : Brake resistor power 100% comes when the power transmitted to the brake resistor is calculated as a percentage, as a mean value over the last 120 sec., on the basis of the resistance value of the brake resistor (parameter 401) and the intermediate circuit voltage.

1. The warning is active when the dissipated braking power is higher than 100%. If Trip [2] has been selected in parameter 403, the frequency converter will cut out while giving this alarm.
