4.1.25 BRD load factor monitoring
When the BRD load factor monitoring function (d103) is selected, the inverter
displays the BRD load factor. If the BRD load factor exceeds the value set as the
dynamic braking usage ratio (b090), the inverter will trip because of the braking
resistor overload protection (error code "E06").

0.0 to 100.0 in steps of 0.1%
4.1.26 Electronic thermal overload monitoring
When the electronic thermal overload monitoring function (d104) is selected, the
inverter displays the electronic thermal overload. If the electronic thermal overload
exceeds 100%, the inverter will trip because of the overload protection (error code
"E05").
