6.2 Ordering Numbers: Brake Resistors
Danfoss offers a wide variety of different resistors that are specially designed for our frequency converters. See
chapter 2.9.4 Control with Brake Function
for the dimensioning of brake resistors. This section lists the ordering numbers for
the brake resistors.
