System overview
2.4 SINAMICS S120 components
Central system components
● Line-side power components, such as fuses, contactors, reactors, and filters for switching
the power supply and meeting EMC requirements.
● Line Modules, which supply power centrally to the DC link.
● DC link components (optional), which stabilize the DC link voltage.
● Adapter Modules 600 (AM600), which supply the distributed S120M with energy and data
via a Hybrid Cable.
To carry out the required functions, SINAMICS S120 is equipped with:
● Control Units that process the drive and technological functions across all axes.
● Supplementary system components that extend the functionality and offer different
interfaces for encoders and process signals.
The central SINAMICS S120 system components are intended 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, side-by-side mounting
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
● Liquid Cooled
Booksize compact format
The booksize compact format combines all benefits of the booksize format and provides the
same performance with an even smaller overall height and an extended overload capability.
The booksize compact format is thus particularly well suited for integration into machines
with high dynamic requirements and confined installation conditions.
The booksize compact format offers the following cooling options:
● Internal air cooling
● Cold plate cooling
