2.1

Overview

Cabinet Applications are components of a modular cabinet unit system. The system is typically
for multi-axis drives with central supply infeed and a common DC link busbar. Typical
applications include, for example, paper machines, rolling mills, test stands, cranes.
All drive components, from the supply infeed to the motor-side inverters, are configured in a
clear, compact layout in the individual Cabinet Applications. Cabinet Applications can be
combined with great flexibility and can be optimally adapted to customer-specific requirements
thanks to a comprehensive array of options.
The main components of the system are as follows:
● Line Connection Modules with line-side components such as contactors, fuses and circuit
breakers, as well as line reactors for Basic Line Modules.
● Line Modules for the infeed using Basic Line Modules for 2-quadrant operation and Active
Line Modules for 4-quadrant operation with line harmonics that can be neglected
● Motor Modules
● Control Units
Standardized interfaces for both the power and the control connections facilitate configuration
and installation. Communication between the power modules and the central Control Unit is
established via DRIVE-CLiQ, the drive-internal serial interface.

Field of application

The modular drive system is used where several motors have to be coordinated in a drive
lineup to realize a multi-axis drive application.
