Brake chopper Conducts the surplus energy from the intermediate circuit of the
drive to the brake resistors 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 chopper module Brake chopper enclosed inside a metal frame or enclosure.
Intended for cabinet installation. See Brake chopper.
Brake chopper unit Brake chopper modules under control of one control board and

Brake resistor Dissipates the drive surplus braking energy conducted by the brake
chopper to heat. Essential part of the brake circuit. See Brake

Operation principle and
hardware description
Contents of this chapter
This chapter describes the operation principle and construction of the brake chopper.
Product overview
ACS880-604 is an air-cooled brake chopper unit. It includes an NBRA brake chopper
module or two parallel-connected NBRA brake chopper modules.
Operation principle
The brake chopper handles the energy generated by a decelerating motor. The chopper
connects the brake resistor to the intermediate DC circuit whenever the voltage in the
circuit exceeds the limit defined by the control program. Energy consumption by the
resistor losses lowers the voltage until the resistor can be disconnected.
Typically, a drive system is equipped with a brake chopper(s) if:
•high capacity braking is needed and the drive cannot be equipped with a regenerative
supply unit
•a backup for the regenerative supply unit is needed.
Standard resistors are available from ABB for each brake chopper module.

Mechanical installation
Contents of this chapter
This chapter contains installation instructions and examples.
Checking the installation site
The brake chopper module must be installed in an upright position. The degree of
protection of the module is IP00. Take this into account when selecting the installation site.
Installation in a cabinet is highly recommended.
Obey the general ACS880 multidrive module cabinet installation instructions given in
Cabinet design and construction instructions for ACS880 multidrive modules
(3AUA0000107668 [English]). In addition, observe these restrictions:
•The brake unit can be grounded to the frame through the mounting screws if the
galvanic connection to PE (protective earth) is good enough.
•Leave 150 mm (5.91 in.) free space below and above the brake chopper module.
•Leave enough space for the fuses and the cooling fan.
•To prevent the module from overheating, do not install it directly above the brake
resistors.
The maximum lengths of the chopper and resistor cables are 5 m and 10 m, respectively.
Required tools
Make sure that you have these tools available:
•drill with suitable bits
•screwdriver and/or wrench with a set of suitable bits
•mounting screws (M6).

20 Mechanical installation
Installing the brake chopper module
1. Mark the locations of the four mounting holes onto the installation surface.
For the module dimensions, see chapter Dimension drawings.
2. Drill the mounting holes. Make sure that dust and burr from drilling does not enter the
module or other equipment at the installation site.
3. Put screws into the holes. Tighten the screws far enough to make sure that they can
carry the weight of the module.
4. Lift the module onto the mounting screws.
5. Tighten the screws.
