10.9 Brake Resistors
In applications where the motor is used as a brake, energy
is generated in the motor and send back into the
frequency converter. If the energy can not be transported
back to the motor it will increase the voltage in the
converter DC-line. In applications with frequent braking
and/or high inertia loads this increase may lead to an over
voltage trip in the converter and finally a shut down. Brake
resistors are used to dissipate the excess energy resulting
from the regenerative braking. The resistor is selected in
respect to its ohmic value, its power dissipation rate and
its physical size. Danfoss offers a wide variety of different
resistors that are specially designed to our frequency
converters. See the section Control with brake function for
the dimensioning of brake resistors. Code numbers can be
found in 5 How to Order.
