Terms and abbreviations
Term/abbreviation Explanation
ACS-AP-x Assistant control panel. An advanced operator keypad for
communication with the drive.
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
