1.5 1.5 SINAMICS S120 components
The following power components are available
● 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.
● Motor Modules, which act as inverters, receive power from the DC link, and supply the
connected motors.
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
interfaces for encoders and process signals.
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
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 suitable for integration into machines
with high dynamic requirements and confined installation conditions.
The Booksize format offers the following cooling options:
● Internal air cooling
● Cold plate cooling
