Brake chopper Conducts the surplus energy from the intermediate circuit of the drive to
the brake resistor when necessary. The chopper operates when the DC
link voltage exceeds a certain maximum limit. The voltage rise is
typically caused by deceleration (braking) of a high inertia motor.
Brake resistor Dissipates the drive surplus braking energy conducted by the brake
chopper to heat. Essential part of the brake circuit. See
Brake chopper .
