Terms And Abbreviations - ABB ACS880-37 Hardware Manual

28 Introduction to the manual

Terms and abbreviations

Term/ Explanation
Abbreviation
BCU Drive control unit. The drive contains two BCU control units. One controls the supply unit,
the other controls the inverter unit.
As standard, the external I/O control signals are connected to the control unit, or optional I/O
extensions mounted on it.
Drive Frequency converter for controlling AC motors. The drive consists of the
line-side converter) and the
the DC link.
In this manual, the term refers to the ACS880-37 as a whole.

Frame (size) Relates to the construction type of the component in question. For example, several drive
types with different power ratings may have the same basic construction, and a frame size is
used in reference to all those drive types.
The frame size marking of the drive indicates the quantity and frame size of the supply
modules, plus the quantity and frame size of the inverter modules, eg. "2×R8i + 2×R8i".
To determine the frame size of a drive type, see the rating tables in chapter
FSO-12 Optional functional safety module
IGBT Insulated gate bipolar transistor; a voltage-controlled semiconductor type widely used in
drives due to their easy controllability and high switching frequency.
Inverter unit The part of the
modules and their auxiliary components.
The inverter unit is also capable of feeding energy from a decelerating motor into the DC
link.
I/O Input/Output
Power module Supply module or inverter module. See also
