Meaning
Application Motor Controller
The digital signal processor is the heart of the control system of the drive.
Ride-through is the ability of the drive to continue the operation in a controlled manner if the
auxiliary power supply is interrupted for a short time.
The auxiliary ride-through function guarantees correct fault indication and proper trip sequencing if
the auxiliary power supply to the drive is lost. The function is activated by a parameter. During ride-
through the power for the control circuits of the drive is supplied by an internal backup system. The
ride-through time is limited by the internal backup system.
Diode Front End
The DFE is the line-side diode rectifier of the drive. The rectifier enables two-quadrant operation of
the drive.
Short form for ACS2000 frequency converter
A cluster is a synonym for a group of hardware modules of the drive control system.
The crowbar is an electrical circuit which is designed to prevent damage from the power electronics
components of the drive if an overvoltage occurs, eg, in the power supply. The overvoltage is
prevented by putting a short-circuit or a low resistance path across the voltage source.
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
DriveDebug is part of ABB's DriveWare
protocol. DriveDebug runs on computers with Windows
specialist's tool used to diagnose, tune and troubleshoot ABB drives.
®
DriveWindow is a DriveWare product. DriveWindow is a 32 bit Windows
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 the equipment status and improve the 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.
Inverter Unit
The INU converts the DC voltage to the required AC motor voltage and frequency.
Term of ABB's I/O system. The I/O module is an active input and output device for digital and 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.
