Terms and abbreviations
Term/Abbreviation Explanation
AGPS Gate driver power supply board. An optional board within drives, used to
implement the Prevention of unexpected start-up function.
APBU Type of optical branching unit used for connecting parallel-connected
converter modules to the RDCU.
ASTO An optional board within drives, used to implement the Safe torque off
function.
CMF Common mode filtering.
DDCS Distributed Drives Communication System; a protocol used in optical fiber
communication inside and between ABB drives.
Drive unit See Motor-side converter .
EMC Electromagnetic Compatibility.
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 this term is used in reference to all those
drive types.
With the ACQ800-37, the frame size of the drive indicates the quantity and
frame size of the inverter modules, e.g. “R8i”.
To determine the frame size of a drive type, see the rating tables in
chapter
Technical data .
IGBT Insulated Gate Bipolar Transistor; a voltage-controlled semiconductor type
widely used in inverters because of their easy controllability and high
switching frequency.
IGBT supply module Bidirectional IGBT bridge and related components enclosed inside a metal
frame or enclosure. Intended for cabinet installation. Used as the supply
module in regenerative and low-harmonic drives.
IGBT supply unit (ISU) See Line-side converter .
Inverter module Inverter bridge, related components and drive DC link capacitors enclosed
inside a metal frame or enclosure. Intended for cabinet installation.
Inverter unit (INU) See Motor-side converter .
Line-side converter A converter that is connected to the supply network and is capable of
transferring energy from the network to the DC link of the drive. With
ACQ800-37 drives of frame size R8i, the line-side converter is also called
the (IGBT) supply unit or the ISU.
