Meaning
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.
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.
Short form for ACS2000 frequency converter
A cluster is a synonym for a group of hardware modules of the drive control system.
Distributed drive control system
DDCS is an acronym for a serial communication protocol designed for data transfer via optical
fibers.
Short form for ACS2000 frequency converter
The drive system includes all equipment used to convert electrical into mechanical power to give
motion to the machine.
Communication link dedicated for ABB drives
DriveWare
DriveDebug is part of ABB's
protocol. DriveDebug runs on computers with
specialist's tool used to diagnose, tune and troubleshoot ABB drives.
DriveWare
DriveWindow is a ® product. DriveWindow is a 32 bit
commissioning and maintaining ABB drives equipped with optical communication links.
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.
Frequency converter and related equipment
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.
Functional earth
Earth
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.
Gate turn-off thyristor
Insulated gate bipolar transistor
Inverter unit of the drive. The INU converts the DC voltage to the required AC motor voltage and
frequency.
Term of ABB's S800 I/O system. The I/O module is an active input or output device for digital or
analog signals.
RMS voltage of the main power supply of the drive
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.
Printed circuit board
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.
