24 Introduction to the manual
Terms and abbreviations
Term/
Abbreviation
Explanation
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.
In this manual, the term refers to the ACS880-07XT 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.
To determine the frame size of a drive type, see the rating tables in chapter Technical data.

FSO-21
Optional functional safety modules
IGBT Insulated gate bipolar transistor; a voltage-controlled semiconductor type widely used in
drives due to their easy controllability and high switching frequency.
I/O Input/Output
Power module Supply module or inverter module. See also Frame (size).
