Rating
The ratings of the resistors must match the particular I
2
t load capability. The resistors can be
dimensioned so that a surface temperature of 300° C can occur briefly (max. 500 ms). In
order to prevent the resistors from being destroyed, braking from the rated speed can occur
max. every 2 minutes. Other braking cycles must be specified when ordering the resistors.
The external moment of inertia and the intrinsic motor moment of inertia are decisive when
dimensioning these resistors.
The kinetic energy must be specified when ordering in order to determine the resistor rating.
Match the ratings of the braking resistors to the ability to withstand I
2
t.
