System overview
2.2 SINAMICS S120 drive system
The electronic rating plate
Electronic type plates in every component represent a digital link to the SINAMICS S120
drive system. They allow all drive components to be automatically identified via the DRIVE-
CLiQ link.
The electronic type plate contains all the relevant technical data about that particular
component. 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.
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
● 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 handles 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 in accordance with EMC requirements
● Standardized design, seamless integration.
