Note Do not use resistances less than than the minimum connection resistance value.
Doing so may damage the Inverter.
Note The usage rate is shown as a percentage of the braking time in one cycle. If one
cycle is 10 seconds, for example, one second of braking is possible using a Brak-
ing Resistor Unit (10% usage rate ED). If the usage rate is to be exceeded, a de-
tailed regeneration energy calculation will be required.
