3.6.13 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 the section
How to order
