System Overview
1.5 SINAMICS S120 components
The following power components are available:
● Line-side power components, such as fuses, contactors, reactors, and filters for switching
● Line Modules, which supply power centrally to the DC link.
● DC link components (optional), which stabilize the DC link voltage.
● Motor Modules, which act as inverters, receive power from the DC link, and supply the
To carry out the required functions, SINAMICS S120 is equipped with:
● A Control Unit that carries out all drive and technological functions across all axes.
● Supplementary system components that enhance functionality and offer different
SINAMICS S120 components were developed for installation in cabinets. They have the
following features and characteristics:
● Easy to handle, simple installation and wiring
● Practical connection system, cable routing in accordance with EMC requirements
● Standardized design, seamless integration
● Internal air cooling (other cooling methods available on request).
Booksize format
Booksize format units are optimized for multi-axis applications and are mounted adjacent to
one another. The connection for the shared voltage-source DC link is an integral feature.
The Booksize format offers various cooling options:
● Internal air cooling
● External air cooling
● Cold-plate cooling
BooksizeCompact format
Derived from the Booksize format we developed the BooksizeCompact format for machines
with particularly high requirements for the compactness of their drives. The
BooksizeCompact format combines all benefits of the Booksize format providing the same
performance with an even smaller overall height and an extended overload capability. The
BooksizeCompact format is thus particularly well suitable for integration into machines with
high dynamic requirements and confined installation conditions.
The BooksizeCompact format has the same design for the cooling methods of internal air
cooling and cold-plate cooling.
