Transient

A momentary deviation in an electrical or
mechanical system

Standardized, comfortable engineering with SIZER and STARTER

As with all SINAMICS drives, the SIZER configuring tool helps

you to select the optimal drive configuration for your application. Graphical support and wizards efficiently guide you
through the selection of necessary components based on your
application.
SINAMICS S120 AC Drives are commissioned using STARTER,
the commissioning tool for the SINAMICS family. Electronic
rating plates ensure automatic and error-free preconfiguration of the drive system. Automatic optimization is a simple
way of optimizing the control response. It ensures fast and
reliable commissioning of the drives.

SINAMICS S120 CUA31 Control Unit adapte

It is also possible to use SINAMICS S120 AC Drives in multi-axis
applications. The drive is connected to a CU320 Control Unit via
the DRIVE-CLiQ interface using the CUA31 Control Unit Adapter.
The CU320 Control Unit then takes over the drive functions for
the AC drive. SIMOTION D modules can be used as a Control
Unit for motion control applications which go beyond the scope
of positioning tasks. SINAMICS S120 AC Drives can also be used
in hybrid operation with SINAMICS S120 multi-axis units in this
configuration (Figure 2). This provides maximum flexibility for
the use of SINAMICS S120 units.

SINAMICS S120 CU310 Control Unit

The use of a SINAMICS S120 AC Drive in a single-axis application
connected to a higher-level control is illustrated in Figure 1. Each
of the AC Drives is equipped with a CU310 Control Unit. This unit
contains the field bus interface for connecting to the higher-level
control. CU310 DP with a PROFIBUS DP connection or CU310 PN
with an integrated PROFINET interface can be selected. In both
cases communication between the control and the drive takes
place in accordance with the standardized PROFIdrive profile.
CU310 offers functions ranging from the simple speed controller to full positioning functionality. Drive-related inputs/outputs
can easily be linked in the CU by means of BICO technology. This
permits the greatest possible options for drive and higher-level
control.
Drive-related inputs/outputs can be linked via the integrated I/O
interface. An integrated TTL/HTL interface and a DRIVE-CLIQ interface are available as encoder interface. For a version with an
integrated motor this encoder interface features the advantage
of an electronic rating plate.
It is easy to implement safety systems using the currently available integrated safety functions such as “Safe standstill” (STO),
“Safe brake control” (SBC) and “Safe stopping” (SS1).

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.
