If the energycannot be transported back to the motor, it will increase the voltage in the drive DC line. In applications with frequent braking and/or high inertia loads,this increase may lead to an overvoltage trip in the drive, and ultimately, a shut down. Brake resistors are used to dissipate the excess energy resultingfrom the regenerative braking. The resistor is selected in respect to its ohmic value, its power dissipation rate and its physical size. Danfoss offers a widevariety of different resistors that are specially designed to our adjustable frequency drives. See the sectionControl with brake function for the dimensioningof brake resistors.
