DRIVE-CLiQ – a digital interface between all components
All SINAMICS S120 components, including the motors and encoders, are interconnected via
a joint 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 type plates in all components
All SINAMICS S120 components with a DRIVE-CLiQ interface have an electronic rating
plate This electronic type plate contains all the relevant technical data about that particular
component. In the 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 type 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
switching the power supply and complying with EMC regulations.
• Power Modules which function as both a power infeed and an inverter.
• 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.
• Motor-side power components, such as motor reactors and dv/dt filters for reducing the
voltage loads on the motor windings.
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.
The 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.
