SINAMICS S120 AC Drive

 SINAMICS S120 AC Drives – a building block
for integrated drive solutions
SINAMICS S120 is a modular drive system with Servo and
Vector Control and is the SINAMICS product most suitable for
demanding drive applications. The stand-alone SINAMICS
S120 AC Drives complement the DC/AC units, which use a
common infeed and controller designed especially for
multi-axis applications. Optimally tailored, integrated solutions can be designed for any type of application based on this
building block system.
The ready-to-connect SINAMICS single drive
SINAMICS S120 AC Drives are designed for single-axis applications but can also be used for multi-axis applications.
Positioning tasks can be reliably executed as well as synchronous movements and motion control tasks. In multi-axis
applications with spatially distributed drives, distributed
solutions based on SINAMICS S120 AC Drives offer a practical
alternative to a central drives line-up.
Universally implementable
SINAMICS S120 AC Drives can easily be implemented in conjunction with higher-level automation systems using field bus
interfaces and the standardized PROFIdrive profile. Solutions
to standard positioning tasks – especially in the SIMATIC PLC
environment – can therefore be found using SINAMICS S120
AC Drives even without in-depth knowledge of drives.
Because it is so easy to combine SINAMICS S120 AC Drives
with other SINAMICS S120 units, multi-axis groupings can be
extended comfortably and economically.
Modular machine components can thus be adapted to high
levels of integration and flexibility in line to varying customer
requirements.
Flexibility through modularity
Every SINAMICS S120 AC Drive is a combination of a Power
Module and a selectable Control Unit or Control Unit Adapter.
An optional filter can also be integrated.
If the AC Drive is operated as a stand-alone single-axis drive,
a Control Unit (e.g. CU310 DP) is added to the Power Module.
It contains the entire control intelligence for the drive, including positioning functions and the field bus interface.
If the AC Drive is combined with other SINAMICS S120 units
to build an integrated multi-axis drive solution, a CUA31 Control Unit Adapter is added to the Power Module in order to
connect the AC Drive to a central Control Unit (e.g. CU320 or
SIMOTION D) via the DRIVE-CLiQ interface in accordance with
the SINAMICS S120 system architecture.
With SINAMICS S120 the modular expansion of your machines
is never limited. Cost-optimized and specific solutions are
ensured since only the components and functions required for
a perfect fit solution are used.
