ABB ACS880-104

The manual is written for readers worldwide. Both SI and imperial units are shown.
Categorization by frame size and option code
The instructions and technical data which concern only certain module or frame sizes are
marked with the size identifier.
The module size can be identified from the basic code visible on the type designation label,
for example, ACS880-104-0100A-3 where 0100A is the module size. The option codes of
the module are listed after the plus sign.
The frame size of a module can be, for example, R1i, R4i, R7i, R8i or 3×R8i (the latter
describing an inverter unit consisting of three parallel-connected R8i inverter modules). See
the technical data for the units and frame sizes.
Use of component designations
Some device names in the manual include the item designation in brackets, for example
[Q20], to make it possible to identify the components in the circuit diagrams of the drive.

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.
