Energy when it is needed: EFC 3610 and EFC 5610 frequency converters from Rexroth.
All over the world, industrial end users are putting more and more
emphasis on energy-efficient machines and systems. By using demandoriented electromechanical energy, users are able to make significant
savings on energy. Speed-controlled motors as pump drives for
example can reduce electricity consumption by up to 80 percent in
comparison to fixed-displacement drives. The EFC 3610 and EFC 5610
frequency converters from Rexroth exploit these potentials simply and
economically. Scalable in performance and functioning, the drives can
be integrated into a wide variety of automation environments with
simple commissioning and open interfaces.
The intelligent frequency converters control speed on demand, thus
significantly reducing the energy consumption of pumps, compressors and
fans. They can be integrated into many different kinds of machines as
compact units for speed and torque control. Together with permanent magnet
motors, the frequency converters increase energy efficiency and the
continuously adaptable pulse frequency minimizes motor noise at the same

Commissioning without a PC
With the integrated control panel, commissioning can be done easily without
programming devices or a PC. From there the user can start auto-tuning or
quickly and easily enter or change the few necessary parameters. With
switchover options between parameter sets and integrated PID control to
increase flexibility as well as various optional I/O and fieldbus modules, the
devices are suitable for any application in machine building.
The LED display can show all operating variables. The removable control
panel has an integrated copy function. This accelerates the commissioning of
several frequency converters with the same or similar parameter set and
reduces the work required when exchanging equipment. The drives have
analog inputs and outputs, which can be used as voltage or current
interfaces. Digital inputs/outputs make simple direct coupling with a PLC
possible. The assembly work required is significantly reduced by the
integrated brake chopper and mains filter as well as time-saving installation
technology using plug-in terminals and an attachment option on standard DIN
rail.
Open interfaces for universal application
The frequency converters from Rexroth can be easily integrated into an
automation network via a Modbus interface included as standard or an
optional PROFIBUS module. With the integrated sequence control with 16
levels, independent sequences can be parameterized. The protection function
for pump operation and motor temperature monitoring protect the system
during critical process conditions.
The two new frequency converter series cover the power spectrum from 0.4
to 18.5 kW. In addition to the freely definable V/f operation, the EFC 5610
also offers vector control for an optimal torque curve. In heavy duty mode, the
overload capacity can be maintained at up to 150 percent for 60 seconds.
The high-torque EFC 5610 frequency converter also offers an optimal start
torque of 200 percent at 0.5 Hz.

The Bosch Group is a leading global supplier of technology and services. In 2013, its roughly
281,000 associates generated sales of 46.1 billion euros. (NB: Due to a change in accounting
policies, the 2013 figures can only be compared to a limited extent with the 2012 figures). Its
operations are divided into four business sectors: Automotive Technology, Industrial
Technology, Consumer Goods, and Energy and Building Technology. The Bosch Group
comprises Robert Bosch GmbH and its roughly 360 subsidiaries and regional companies in
some 50 countries. If its sales and service partners are included, then Bosch is represented in
roughly 150 countries. This worldwide development, manufacturing, and sales network is the
foundation for further growth. In 2013, the Bosch Group invested some 4.5 billion euros in
research and development and applied for some 5,000 patents. This is an average of
20 patents per day. The Bosch Group’s products and services are designed to fascinate, and
to improve the quality of life by providing solutions which are both innovative and beneficial. In
this way, the company offers technology worldwide that is “Invented for life.”
