Energy efficiency

Up to 70 % potential for savings using variable speed operation
SINAMICS enables great potential for savings to be realized by
controlling the motor speed. In particular, huge potential savings
can be recovered from pumps, fans and compressors which are
operated with mechanical throttle and valves. Here, changing to
variable-speed drives brings enormous economic advantages.
In contrast to mechanical control systems, the power consump-
tion at partial load operation is always immediately adjusted to
the demand at that time. So energy is no longer wasted, per-
mitting savings of up to 60 % – in exceptional cases even up to
70 %. Variable-speed drives also offer clear advantages over
mechanical control systems when it comes to maintenance and
repair. Current spikes when powering up the motor and strong
torque surges become things of the past – and the same goes
for pressure waves in pipelines, cavitation or vibrations which
cause sustainable damage to the plant. Smooth starting and
ramp-down relieve the load on the mechanical system, ensuring
a significantly longer service life of the entire drive train.
Regenerative feedback of braking energy
In conventional drive systems, the energy produced during
braking is converted to heat using braking resistors. Energy
produced during braking is efficiently recovered to the supply
system by versions of SINAMICS G and SINAMICS S inverters
with regenerative feedback capability and these devices do not
therefore need a braking resistor. This permits up to 60 % of the
energy requirement to be saved, e.g. in lifting applications.
Energy which can be reused at other locations on a machine.
Furthermore, this reduced power loss simplifies the cooling of
the system, enabling a more compact design.
Energy transparency in all configuration phases
Early on, in the configuration phase, the SIZER for Siemens
Drives engineering tool provides information on the specific
energy requirement. The energy consumption across the entire
drive train is visualized and compared with different plant
concepts.
SINAMICS in combination with energy-saving motors
Engineering integration stretches beyond the SINAMICS drive
family to higher-level automation systems, and to a broad spec-
trum of energy-efficient motors with a wide range of performance
classes, which, compared to previous motors, are able to
demonstrate up to 10 % greater efficiency.
Variants
Depending on the application, the SINAMICS range offers the ideal variant for any drive task.
Platform concept
All SINAMICS variants are based on a platform concept. Joint
hardware and software components, as well as standardized
tools for dimensioning, configuration, and commissioning tasks
ensure high-level integration across all components. SINAMICS
handles a wide variety of drive tasks with no system gaps. The
different SINAMICS variants can be easily combined with each
other.
Quality management according to EN ISO 9001
SINAMICS conforms to the most exacting quality requirements.
Comprehensive quality assurance measures in all development
and production processes ensure a consistently high level of
quality.
Of course, our quality management system is certified by an
independent authority in accordance with EN ISO 9001.
IDS – Integration at its very best
The Siemens Integrated Drive Systems (IDS) solution offers per-
fectly matched drive components with which you can meet your
requirements. The drive components reveal their true strengths
as an Integrated Drive System over the full range from engineer-
ing and commissioning through to operation: Integrated system
configuration is performed using the Drive Technology Configu-
rator: Just select a motor and a converter and design them with
the SIZER for Siemens Drives engineering tool. The STARTER
commissioning tool integrates the motor data at the same time
and simplifies efficient commissioning. Integrated Drive Systems
are incorporated in the TIA Portal – this simplifies engineering,
commissioning and diagnostics.
SINAMICS V converters focus on
the essentials both in terms of hardware
and functionality.
This results in a high degree of ruggedness
combined with lower investment costs.
SINAMICS G converters function perfectly for
low and medium demands on the dynamic
response of the control system.
SINAMICS S converters are predestined
for demanding single- and multi-axis
applications in machine and plant engineering
as well as for numerous motion control tasks.
