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.
● Motor Modules, which act as inverters, receive power from the DC link, and supply the
connected motors
● Power components on the motor side, such as reactors and Voltage Protection Modules,
which allow output currents and output voltages to be reduced
To carry out the required functions, SINAMICS S120 is equipped with:
● Control Units that process the drive and technological functions across all axes
● Additional system components to expand the functionality and to handle various
interfaces for encoders and process signals
SINAMICS S120 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
Note
Installation location in the cabinet
As a general rule, SINAMICS S120 components must be mounted vertically in the control
cabinet. Other permissible installation locations are given in the descriptions for the
individual components.
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
