Note
A list of certified components is available on request from your local Siemens office.
1.2 SINAMICS S120 drive system
Modular system for sophisticated drive tasks
SINAMICS S120 solves complex drive tasks for a wide range of industrial applications and
is, therefore, designed as a modular system. Users can choose from many different
harmonized components and functions to create a solution that best meets their
requirements. SIZER, a high-performance engineering tool, makes it easier to choose and
determine the optimum drive configuration. SINAMICS S120 is supplemented by a wide
range of motors. Whether synchronous or asynchronous, all motor types are supported by
SINAMICS S120.
Particularly suitable for multi-axis applications
Coordinated drives that carry out drive tasks together are used in many mechanical and
plant engineering applications, including running gears in gantry cranes, stretching systems
in the textile industry, or paper machines and rolling mills. These require drives with a
connected DC link, which allows cost-saving energy balancing between braking and driving
axes.
SINAMICS S120 features Power Modules (AC-AC converters), Line Modules (infeed
modules) and Motor Modules (inverter modules) covering a wide power range which, having
been designed for seamless integration, pave the way for compact multi-axis drive
configurations.

Fig. 1-3 Overview of the SINAMICS S120 system
New system architecture with a central Control Unit
Electronically coordinated individual drives work together to perform your drive tasks. Higher-
level controllers operate the drives to achieve the required coordinated movement. This
requires cyclic data exchange between the control and all the drives. This exchange always
had to take place via a field bus, which required a great deal of time and effort for installation
and configuration. SINAMICS S120 takes a different approach. A central Control Unit
controls the drive for all connected axes and also establishes the technological links between
the drives and/or axes. Since all the required data is stored in the central Control Unit, it
does not need to be transferred. Inter-axis connections can be established within a Control
Unit and easily configured in the STARTER commissioning tool using a mouse.
Simple technological tasks can be carried out by the SINAMICS S120 Control Unit itself. For
complex numerical or motion-control tasks, high-performance SIMOTION D modules are
used instead.

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.
