ABB DSDX180A analog input/output board
Delivery comprises the following items (see the fig ure below):
• Drive (1)
• Transformer (can be integrated or non-inte grated) (2)
Fan unit(s) (3), shipped separately.
• The number of fan units delivered depends on
the cooling configuration ordered.
• Rating label (4)
• Door keys (5)
• Phase module replacement kit (6) (if selected as
additional option).
- Note: This kit varies depending on the drive
output type.
• Sealing compound (7) (only when 6-hole cable
entry is provided).
Identifying the delivery
The drive and accessories are identified by the type
code printed on the rating label. The rating label is
located on the front of the control compartment
door.
The label provides information on the type of drive,
the rated voltage, the frequency and the current of
the main and the auxiliary power supply

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 Motor Controller
The digital signal processor is the heart of the control system of the drive.
Auxiliary ride-through 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.
DFE Diode Front End
The DFE is the line-side diode rectifier of the drive. The rectifier enables two-quadrant operation of
the drive.
Converter Short form for ACS2000 frequency converter
Cluster A cluster is a synonym for a group of hardware modules of the drive control system.
Crowbar 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.
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 the equipment status and improve the 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.
INU Inverter Unit
The INU converts the DC voltage to the required AC motor voltage and frequency.
IOEC module Term of ABB’s 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.
