Overview

SINAMICS S120 Cabinet Modules are the components of a modular cabinet unit system for
multi-motor drives with a central supply infeed and a common DC link busbar, as typically
found in the process industry, automotive industry, metal processing industry as well as in
the crane and mining domains.
They contain liquid-cooled built-in units from the SINAMICS S120 product series, thus
making them an ideal supplement to the SINAMICS G150 and SINAMICS S150 series of
cabinet units for single drives.
All drive components, from the supply infeed to the motor-side inverters, are configured in a
clear, compact layout in the individual Cabinet Modules. They 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:
● Basic Line Connection Modules with line-side components such as contactors, fuses,
circuit breakers, line reactors and line filters for two-quadrant operation.
● Active Line Connection Modules with line-side components such as contactors, fuses and
circuit breakers and Active Interface Modules for four-quadrant operation with line
harmonics that can be neglected
● Motor Modules
● Control Units
● Heat Exchanger Modules
Standardized interfaces for both the power and the control connections facilitate
configuration and installation. Communication between the Power Modules and the central
Control Unit takes place via DRIVE-CLiQ, the internal drive serial interface.
