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.

SINAMICS S120 – AC Drives for single-axis applications

AC Drives for
single-axis applications
•  An autonomous single-axis
SINAMICS S120 AC Drive comprises
a Control Unit and Power Module
•  Alternatively, a Power Module can
be integrated into a multi-axis
group via CU adapter
•  Power Modules are available in the
Blocksize and Chassis formats
Typical applications
Single-axis drives are suitable for applications in all sectors, such as e.g. for travel
drives, centrifuges, elevators and extruders as well as for mixers and kneaders.
Single-axis SINAMICS S120 AC Drives are
also the ideal solution for multi-axis applications where the drive axes are located remotely from one another. The same
applies to modular machine concepts
that are being increasingly implemented
in the packaging and woodworking industries.
For a single-axis drive, the line supply
infeed and the power supply of the motor are combined in one device – the
so-called Power Module. For single-axis
applications, a special Control Unit (e.g.
CU310) mounted on the Power Module
handles the drive control; for multi-axis
applications a Control Unit is used (e.g.
CU320) coupled through DRIVE-CLiQ.
In the latter case, instead of the Control
Unit, a CU Adapter is mounted on the
Power Module.
For instance, SINAMICS S120 AC Drives
decentrally coupled to a higher-level
control via PROFIBUS DP or PROFINET can
reliably handle e.g. positioning tasks in
automated assembly machines and handling systems.

SINAMICS S120 for high-performance single- and multi-axis applications

The modular system for highperformance applications
The innovative SINAMICS S120 hardware
and software concept tackles sophisticated drive tasks in industrial applications
with a power range extending from 0.12
through to 4,500 kW:
SINAMICS S120 offers high-performance
individual AC/AC drives in the Blocksize
and Chassis formats as well as coordinated DC/AC drives for multi-axis applications in the Booksize Compact and Chassis formats and Cabinet Modules.
Increased flexibility with central
control intelligence
For SINAMICS S120, the drive intelligence
is combined together with the control
functions in Control Units (CU), which
handle both vector and servo control as
well as V/f control. For all drive axes, they
also handle the speed and torque control
as well as additional intelligent drive
functions.
Performance can be freely selected for
vector and servo controls
SINAMICS S120 vector control is recommended for drive solutions involving continuous material webs – for instance,
wire drawing, foil making and paper machines – as well as for hoisting gear, centrifuges and marine drives with harmonious, rotary motion. Servo control with
SINAMICS S120 is used for cyclic processes with precise and fast closed-loop
position control using servomotors. For
instance, this includes applications in the
packaging and printing industries as well
as machine tools.

The response to increasing demands
Today, machines must be able to be
manufactured more cost-effectively and
at the same time they should offer operating companies increasingly higher levels
of productivity. The SINAMICS S120 drive
concept fulfills both of these tasks! Engineering times are shortened due to the
fact that it can be engineered in a userfriendly fashion. Its high dynamic performance and accuracy permits higher cyclic
machine rates for a maximum
degree of productivity. Not only this, its
simple handling and maintenance increases the degree of availability and reduces the life cycle costs. When considering
everything: SINAMICS S120 increases the
competitiveness of both machine manufacturers and operating companies.
Modularity for machine construction
SINAMICS S120 allows power and control
performance to be freely combined.
Multi-axis drive solutions with higherlevel motion control can be implemented
using the modular SINAMICS S120 drive
system just the same as solutions involving single-motor drives. This means that
the machines can be designed to be
fully modular therefore addressing the
growing number of different versions.
Where modules or individual components
are to be combined or innovated,
SINAMICS S120 guarantees the perfect
compatibility between all of the system
components without requiring any major
engineering costs.
