SINAMICS S120 Cabinet Modules NEMA are the components of a modular cabinet unit
system for multi-motor drives with central line supply and a common DC link busbar, as
typically found in paper-making machines, roller mills, test stands, and 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 line supply 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
circuit breakers, as well as line reactors for Basic Line Modules.
● Line Modules for the infeed in the following versions:
– Basic Line Modules for two-quadrant operation
– Smart Line Modules for four-quadrant operation
– Active Line Modules for four-quadrant operation with negligible line harmonics
● The following types of Motor Module:
– Booksize Cabinet Kits
– Chassis format
● Control Units
● Auxiliary Power Supply Modules to supply the auxiliary power supply system
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 drive-internal serial interface.
