Terms and abbreviations
The following table lists terms and abbreviations
you should be familiar with when using the manual.
Some of the terms and abbreviations used in the manual are unique to ABB and might differ from
the normal usage.
Term / Abbreviation Meaning
AMC circuit board Application and Motor Controller
The digital signal processor is the heart of the control system of the drive. A separate AMC circuit
board is assigned to the line-side rectifier (AFE) and the motor inverter (INU) of the drive.
AFE Active Front End
The AFE, also referred to as ARU (Active Rectifier Unit), is the line-side rectifier of the drive that
enables four-quadrant operation and reactive power compensation.
Converter Short form for ACS2000 frequency converter
Cluster A cluster is a synonym for a group of hardware modules of the drive control system.
DDCS Distributed drive control system
DDCS is an acronym for a serial communication protocol designed for data transfer via optical
fibers.
Drive Short form for ACS2000 frequency converter
Drive system The drive system includes all equipment used to convert electrical into mechanical power to give
motion to the machine.
DriveBus Communication link dedicated for ABB drives
DriveDebug DriveDebug is part of ABB’s DriveWare® software tools for drives using the DDCS communications
protocol. DriveDebug runs on computers with Windows® operating systems. DriveDebug is a
specialist’s tool used to diagnose, tune and troubleshoot ABB drives.
DriveWindow DriveWindow is a DriveWare® product. DriveWindow is a 32 bit
Windows
® application for
commissioning and maintaining ABB drives equipped with optical communication links.
DriveMonitor DriveMonitor is a monitoring and diagnostics system that allows secure access to the drive via the
internet from a remote location. DriveMonitor provides long-term monitoring functions that allow
to infer equipment status and improve equipment performance.
Equipment Frequency converter and related equipment
EMC Electromagnetic compatibility
All measures to suppress electromagnetic disturbances caused by different electrical equipment in
the same electromagnetic environment, and to strengthen the immunity of the equipment to such
disturbances.
FE Functional earth
Ground Earth
To ground The conducting path (eg, conductor) between the electric equipment (eg, frequency converter) and
the earth. The electric equipment is connected to the earth, eg, by a grounding set or a grounding
switch.
GTO Gate turn-off thyristor
IGBT Insulated gate bipolar transistor
INU Inverter unit of the drive. The INU converts the DC voltage to the required AC motor voltage and
frequency.
IOEC module Term of ABB’s S800 I/O system. The I/O module is an active input and output device for digital and
analog signals.
Line voltage RMS voltage of the main power supply of the drive
MCB Main circuit breaker
The MCB is a major protection device of the drive system and connects / disconnects the main
power supply to the drive. The MCB is controlled entirely by the drive.
PCB Printed circuit board
PCC Point of common coupling. The PCC is the point in the electrical power supply system where the
responsibility of the utility changes to the industrial customer. The utility is responsible to provide
clean voltage and current with respect to harmonic distortion up to the PCC. The industrial
customer is responsible not to distort voltage and current by its electrical systems.
PE Protective earth
Phase module The phase module is a compact assembly of wired components including power semiconductors
and circuit boards that serves as a standardized building block for the AFE and INU of the drive.
PPCS Power plate communication system
PPCS is an acronym for a serial communication protocol designed for data transfer via optical fibers
between AMC circuit board and INTerface circuit boards.
RTD Resistance temperature detector or device
The RTD is a temperature sensor where the change in electrical resistance is used to measure the
temperature.
