12 About this manual
Further information
Address any inquiries about the product to your local ABB representative, quoting the type
code and serial number of the unit. If the local ABB representative can not be contacted,
address inquiries to nearest country that has support for wind turbine converters. See
detailed contact information from the back cover of this manual.
In case of fault situations, ensure that the information stated below is available to get fast
problem solving assistance:
• fault logger data
• data logger files (data logger 1 and data logger 2) from grid-side and rotor-side
converter control programs
• parameter files from the grid-side and rotor-side converter control programs.
In DriveWindow,
• save the parameters with File / Parameters / Save as command to a .dwp file (for
instructions, see page 100)
• copy the fault data from the Fault logger view and paste it to a .txt file
• copy the graphs from the Data logger view.

Abbreviation Explanation
BAMU Auxiliary measurement unit
DFIG Doubly-fed induction generator
DTC Direct Torque Control
Grid-side
converter
A converter that is connected to the electrical power network (grid) and is capable of
transferring energy from the converter DC link to the grid and vice versa. The grid-side
converter is also called ISU (see ISU).
IGBT Insulated gate bipolar transistor
ISU IGBT supply unit. IGBT supply modules under control of one control board, and related
components.
INU Inverter unit. Inverter module(s) under control of one control board, and related
components. One INU typically controls one generator.
LVRT Low-voltage ride-through
NAMU Auxiliary Measuring Unit. Performs voltage measurement for RMIO board of the grid-
side converter.
NUIM Voltage and Current Measurement Unit. Performs voltage and current measurement for
AMC board.
MCB Main circuit breaker
PLC Programmable logic controller
PWM Pulse width modulation
Rotor-side
converter
A converter that is connected to the generator rotor and controls its operation. The rotor-
side converter is also called INU (see INU).
RUSB USB-DDCS adapter
Wind turbine
converter
A converter for controlling AC generators in wind turbine applications.
WTC Wind turbine controller
