Central and Distributed Drive Systems
0.075 kW to 120 kW

Central drive systems:

Central drive systems offer a wide performance range based
on modular design. All components of the SIMODRIVE® 611
modular system, such as mains supply and power modules can
be used.

The SIMODRIVE 611 universal regulated control
plug-in unit provides you with a simple digital drive for all motor
types and for various encoder systems. SIMODRIVE 611 universal
offers integrated positioning functions and numerous
communications interfaces for flexible integration in higherlevel
control systems. The twoaxis modules support spacesaving
module configurations.

Distributed drive systems:

With distributed drives, the drive technology is relocated at the
machine. The advantages of this technology lie in the system
configuration and installation technique: The control cabinet
costs are reduced, mounting at the machine is simplified by the
use of complete self-contained units and the installation costs
are reduced by simplified cable routing.

The benefits of distributed drive configurations are most apparent
in the case of large scale machines and installations.
The following versions are available:
CA: The converter system for mounting at the motor that
makes Motion Control tasks possible
The servo drive that is also capable of interpolating motion tasks

The intelligent positioning motor

With a proven hardware platform,
the new SIMODRIVE 611
universal has been designed to
handle a wide range of applications
in the mechanical
engineering industry. It can be
used to control various motor
types, such as synchronous
servo, asynchronous servo,
standard induction or linear
motors. Its compact, multi-axis
design is well suited for many
industries – i.e. printing, packaging,
textile, wood and glass.

SIMODRIVE 611 universal is
supplied for line voltages of
3-phase 380 V to 480 V AC,
50/60 Hz and is available from
1.1 kW to 120 kW. The modules
have a standard design of
480 mm high by 288 mm deep
and depending on the power
range, the width increases in
units of 50 mm.

Some of the main features of the
SIMODRIVE 611 universal:
• Configurable for speed/torque
control and positioning control
• Suitable for synchronous and
induction motors
• Compact design with singleaxis
and two-axis modules
• Communication with PROFIBUS
• All data in the package is located
on a traversable memory
In addition to classical drive
functions such as torque and
speed control with output frequencies
up to 1400 Hz, SIMODRIVE
611 universal offers
integral positioning functions.

Up to 64 independent traversing
blocks can be stored to perform
either absolute or relative
position moves allowing it to be
characterized by:
• Extremely high dynamic performance
• Flexible positioning
• High field weakening range
• Ease of use.
The range is rounded off by a
complete spectrum of system
components and accessories.
Customer-specific, integral solutions
(automation – converters
– motors) are available for the
most varied of applications in all
industrial sectors.

For the SIMODRIVE 611 universal,
an easy to use Windows
based graphical programming
and diagnostic tool is available.
Known as SIMOCOM U, this tool
has been specially developed
to make start up of the drive system
Siemens’ worldwide service
and the company’s sales network
enable all our customers to
obtain direct access to expert
advice and project planning as
well as training and service.

Distributed drive systems with SIMODRIVE POSMO

Installation at the machine or integrated in the motor: For distributed solutions, the servo drives of the SIMODRIVE POSMO series designed to a high degree of protection take drive technology out of the control cabinet and put it right on the machine.

Flexibility in machine design, low wiring overheads, rapid installation and start-up, short retooling times, easy maintenance and high availability are obvious advantages for the
OEM and machine operator when using SIMODRIVE POSMO drives.

This significantly reduces system costs and project engineering and installation times.

The SIMODRIVE POSMO series, with its consistent distributed design concept, opens up a new level in automation and can be used throughout the mechanical engineering sector, particularly in the fields of packaging, presses, wood, glass, printing, plastics, textiles and machine tools.

PROFIBUS-DP – Control bus and drive bus in one

PROFIBUS-DP is a multi-vendor, open fieldbus standard with a wide field of application
in manufacturing and process automation. Multi-vendor capability and openness is guaranteed by the EN 50170 and EN 50254 international standards. PROFIBUS-DP is suitable for high-speed, time-critical applications as well as for complex communications tasks.

PROFIBUS-DP is the most frequently used communications profile. It is optimized for speed, efficiency and low connection costs and is specially designed for communication between automation systems and distributed I/O.

The new functionality for synchronous operation (regulated control and synchronization of
drives over the bus) and direct communication (between drives and the I/O) means that a
special drive bus is no longer necessary.

For full automation of your machine,you only need one bus:PROFIBUS-DP. The following
functions can be implemented with PROFIBUS-DP:
• Unregulated control
• Operator control and visualization
• Actuators, sensors
• Motion Control functions
• Engineering, diagnostics and

The benefits of PROFIBUS-DP for total automation of the machine
are clear:
Less hardware, less wiring, less installation, lower engineering costs, fewer mistakes with fast commissioning and minimal training costs.
