Overview

SINAMICS S120 Cabinet Modules are the components of a modular cabinet unit system for
multi-axis drives with a central supply infeed and a common DC link busbar, as typically
found in paper-making machines, roller mills, test stands, or hoisting gear.
They contain 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:
● Line Connection Modules with line-side components such as contactors, fuses, and
● Line Modules for the infeed in the following versions:
● Central Braking Modules for short-term braking
● The following types of Motor Module:
● Auxiliary Power Supply Modules to supply the auxiliary power supply system
● 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 takes place via DRIVE-CLiQ, the internal drive serial interface.
