If the energy can notbe 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 thisincrease 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 fromthe regenerative braking. The resistor is selected in respect to its ohmic value, its power dissipation rate and its physical size. Danfoss offers a wide varietyof different resistors that are specially designed to our frequency converters. See the sectionControl with brake function for the dimensioning of brakeresistors.
