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, these data include the parameters of the electric
equivalent circuit diagram and characteristic values for the built-in motor encoder. The
Control Unit records these data automatically via DRIVE-CLiQ so that they do 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 these 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.
