Term/Abbreviation Explanation
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. Refer
to Brake chopper.
Control board Circuit board in which the control program runs.
Capacitor bank Refer to DC link capacitors.
