System overview
1.2 SINAMICS S120 drive system
DRIVE-CLiQ – the digital interface between all components
All SINAMICS S120 components, including the motors and encoders, are interconnected by
a shared serial interface called DRIVE-CLiQ. The standardized cables and connectors
reduce the variety of different parts and cut storage costs.
Converter boards (Sensor Modules) for converting standard encoder signals to DRIVE-CLiQ
are available for third-party motors or retrofit applications.
Electronic rating plates in all components
All SINAMICS S120 components with a DRIVE-CLiQ interface have an electronic rating
plate. This electronic rating plate contains all the relevant technical data about that particular
component. For motors, for example, this data includes the parameters of the electric
equivalent circuit diagram and characteristic values for the built-in motor encoder. The
Control Unit records this data automatically via DRIVE-CLiQ so that it does not need to be
entered during commissioning or when the equipment is replaced.
In addition to the technical data, the rating plate includes logistical data (manufacturer ID,
order number, and globally unique ID). Since this data can be called up electronically on site
or remotely, all the components used in a machine can always be individually identified,
which helps simplify servicing.
SINAMICS S120 components
The SINAMICS S120 components are primarily used for multi-axis drive tasks.
The following power components are available:
● Line-side power components, such as fuses, contactors, line reactors and line filters for
● Line Modules, which supply power centrally to the DC link.
● DC-link components which are used optionally to stabilize the DC-link voltage.
● Motor Modules, which act as inverters, receive power from the DC link, and supply the
● Motor-side components, such as sine-wave filters, motor reactors, and dV/dt filters for
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.
● Additional system components that enhance functionality and offer different interfaces for
