Explanation
Main Circuit Interface Board
Application and Motor Controller Board. Part of the NDCU Drive
Control Unit
Power Supply Board
The cubicle with auxiliary devices such as auxiliary voltage circuit
breakers, control electronics, measurement boards, etc. The slide-
out frame is located in the auxiliary control cubicle.
Converts electric power from one form to another.
Distributed Drives Communication System. Communication protocol
used with fibre optic link.
Direct Torque Control
Electromagnetic Compatibility
Insulated Gate Bipolar Transistor. A voltage controlled
semiconductor type widely used in converters due to their easy
controllability and high switching frequency.
Inductance - capacitor - inductance filter
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.
Auxiliary Measuring Unit. Performs voltage measurement for IGBT
supply unit RMIO board.
CANopen® Adapter Module
Drive Control Unit. Consists of a NAMC board and NIOC board built
into a metal housing. NDCU-33 unit controls the rotor-side converter.
Ethernet Adapter Module
Input/Output Board. Part of the NDCU Drive Control unit
Profibus-DP® Adapter Module
PPCS branching unit. Module connected with RDCU/NDCU parallel.
Pulse Encoder Interface Module
Voltage and Current Measurement Unit
Cubicle with grid and stator cable terminals, main switching and
disconnecting devices, etc.
Power Plate Communication System. Communication protocol used
with optic fibre link which controls the power stage of the converter
modules.
DDCS Communication Option with optic fibre channels
Drive Control Unit which contains an RMIO (Motor Control and I/O)
board. An RDCU unit controls the grid-side converter.
