Siemens SINAMICS S120 Equipment Manual page 27

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
drive axes.
Using the closed-loop control techniques available, both synchronous as well as induction
motors can be operated, and therefore the complete range of low-voltage motors from
Siemens.
Integrated PROFIBUS DP interfaces ensure easy integration into complete automation
solutions. PROFINET is another of the fieldbus interfaces supported by the system.
Benefits
SINAMICS S120 sets itself apart through:
● Can be universally used in high-performance single and multi-axis applications
● Can be freely combined to create customized solutions
● Wide range of power ratings
● Wide range of functions
● SINAMICS Safety Integrated functions
● Supports various cooling types (air/liquid-cooled)
● Supports various infeed concepts
● Can be simply integrated into higher-level automation and IT environments
● User-friendly engineering
● Ease of handling
● Simple installation
● Practical connection system
● Auto-configuration with electronic rating plates
Control Units
The closed-loop control intelligence for all the drive axes integrated in the multi-axis group is
combined in the Control Units. They also feature drive-related inputs/outputs and interfaces
for communicating with higher-level control systems. Control Units are available with
different functional scopes and with various performance levels.
DRIVE-CLiQ – the digital interface between the components
SINAMICS S120 components, including motors and encoders, are equipped with the high-
performance DRIVE-CLiQ system interface.
Line and Motor Modules for example are connected to the Control Unit – and Terminal
Modules and Sensor Modules to the drive system via DRIVE-CLiQ – simply and efficiently.
Motors that also have this interface can be directly connected to the drive system.
Converter boards (Sensor Modules) for converting standard encoder signals to DRIVE-CLiQ
are available for third-party motors or retrofit applications.
