SINAMICS S120 is supplemented by a wide range of motors. SINAMICS S120 optimally supports:
• SINAMICS S120M
• Synchronous and induction motors
• Linear and torque motors
System architecture with a central Control Unit
On the SINAMICS S120, the drive intelligence is combined with closed-loop control functions
into Control Units. These units are capable of controlling drives in the vector, servo and V/f
control modes. They also perform the speed and torque control functions plus other intelligent
drive functions for all axes on the drive. Inter-axis connections can be established within a
component and easily configured by mouse click in the Startdrive or STARTER commissioning
tool.
Functions for higher efficiency
• Basic functions: Speed control, torque control, positioning functions
• Intelligent starting functions for independent restart after power supply interruption
• BICO technology with interconnection of drive-related I/Os for easy adaptation of the drive
system to its operating environment
• Integrated safety functions for rational implementation of safety concepts
• Regulated infeed/regenerative feedback functions for preventing undesirable reactions on
the supply, allowing recovery of braking energy and ensuring greater stability against line
fluctuations.
DRIVE-CLiQ – the digital interface between SINAMICS components
Most of the SINAMICS S120 components, including the motors and encoders, are connected to
each other via the common DRIVE-CLiQ serial interface. The standardized cables and connectors
reduce the variety of different parts and cut storage costs. Encoder evaluations 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 have to be entered manually
during commissioning or component replacement – helping to ensure that drives are
commissioned more reliably.
The rating plate contains all the relevant technical data about that particular component. For
motors, these are the parameters of the electrical equivalent circuit diagram and key values of
the integrated motor encoder, for example.
In addition to the technical data, the type plate includes logistical data (manufacturer ID, article
number and 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.
