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 stock inventory 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
An important digital linkage element of the SINAMICS S120 drive system are the electronic
type plates integrated in every component. They allow all drive components to be detected
automatically via a DRIVE-CLiQ link. As a result, data does not need to be entered manually
when commissioning or replacing components – making commissioning even more secure
and reliable!
The electronic rating plates of the motors contain, for example, the parameters of the
electrical equivalent circuit diagram and the characteristic data of the integrated motor
encoder in addition to information such as article and identification numbers.
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.
• 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
connected motors.
• Motor-side components, such as sine-wave filters, 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.
• Additional 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 according to EMC requirements
• Standardized design, seamless integration.
