Note Donotuseresistancesless than thantheminimumconnection resistancevalue.
Doing so may damage the Inverter.
Note The usage rate is shown as a percentage of the braking time in one cycle. If one
cycleis10seconds,forexample,onesecondofbrakingispossibleusingaBrak-
ing Resistor Unit (10% usage rateED). If the usagerate is tobeexceeded, a de-
tailed regeneration energy calculation will be required.
