Modular system toolbox for complex drive tasks
SINAMICS S120 can be used to solve complex drive tasks for a very wide spectrum of
industrial applications and consequently designed as a modular system toolbox. From a wide
range of matched components and functions, the user uses just the combination that best
meets the user's requirements. The powerful SIZER configuration tool simplifies the
selection and the determination of the optimum drive configuration.
SINAMICS S120 is supplemented with a large range of motors. Irrespective whether
synchronous or asynchronous motors, SINAMICS S120 optimally supports them all.
Drive for multi-axis applications
The trend to desynchronization in machine construction continues uninterrupted. Unless it
has already been done, central drives will be replaced by electronically-coordinated servo
drives. These require drives with coupled DC link to provide a cost-effective energy
compensation between braking and driving axes.
SINAMICS S120 has a wide power range using power feeds and inverter modules designed
for a smooth installation in its type and which permit space-saving multi-axis drive
configurations.
New system architecture with central control unit
Electronically-coordinated single drives solve your drive task together. Overlaid controllers
control the drives so that the required coordinated motion results. This requires a cyclical
data exchange between the controller and all drives. Previously, this exchange had to be
realized using a fieldbus with the associated installation and configuration cost. SINAMICS
S120 follows new paths here: a central control unit performs as master the drive control for
all attached axes and also realizes the technological links between the axes. Because all
required information is present in the central control unit, it does not need to be transferred
with difficulty. Inter-axis couplings can be realized within a component and are configured in
the STARTER commissioning tool with a mouse click.
The SINAMICS S120 control unit solves simple technological tasks by itself. For complex
numeric or motion control tasks, it is replaced by powerful modules from the SINUMERIK
840D sl product spectrum.
DRIVE-CLiQ – the digital interface between SINAMICS components
The SINAMICS S120 components, including the motors and encoders, are connected with
each other using the shared DRIVE-CLiQ serial interface. The standardized form of the
cable and plug engineering reduces the range of parts and the storage costs.
Converter modules for the conversion of traditional encoder signals to DRIVE-CLiQ are
available for non-Siemens motors or retrofit applications.
