This means that the brake resistor’s continuous rating P
DB
will always be
lower than maximum pulse power P
Peak
by the DF[%] factor.
Resistance R
B
must be at least as high as the breaking transistor’s minimum
permissible resistance R
min
.
￫
Use brake resistors with the recommended R
Brec
resistance
values for the DA1 variable frequency drives’ ratings.

For the rated brake resistors for DA1 variable frequency drives,
please refer to the technical data chapter in
