SINAMICS S120 is supplemented by a wide range of motors. Whether torque, synchronous
or induction motors, whether rotating or linear motors, all of these motors are optimally
supported by SINAMICS S120.
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
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 in the STARTER/Startdrive commissioning tool using a
mouse.
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.
