• Standard braking option as basic functionality.
Can thus be used for many applications even
without additional components
• For stringent braking requirements, dynamic
braking with integrated chopper control.
Thus, the load can be stopped in a controlled
manner, irrespective of the load.
• Extensive safety mechanisms protect your investment and installation
• High availability in the event of voltage fluctuations on the power supply. With the Vdc max controller, automatic adjustment of the deceleration ramp
prevents the inverter from shutting off unintentionally during deceleration with high inertia loads.
This enables controlled deceleration of the motor
in the event of a power failure. During short voltage drops, the Vdc min controller bridges the power
failure without compromising application performance.
• Just the right device for every application thanks to
graded functionality of all three models
• DIP switch for easy switchover of the factory setting
from IEC to NEMA motor data
• Free function blocks allow for simple logic tasks
and sequence control tasks such as interlocks
directly in the inverter even without external miniature controllers. Thanks to the BICO functionality,
the assignment of inputs and outputs is user-definable, as is the wiring of parameters.

MICROMASTER 420:
Heavy-duty frequency inverter for Schulthess:
Industrial washing machines
MICROMASTER 430:
Fully automatic water treatment at the zoo:
High-performance inverters for a wide range of tasks
The task
Schulthess, a well-established Swiss company, has been
successfully manufacturing washing machines for industrial
and commercial applications for the past 100 years. In order to achieve optimum results, washing machines for use
in industry must exhibit flexibility and the ability to adapt to
an intelligent wash process. During this process, the heavy
drum filled with laundry must operate at various speeds,
including high speeds during the spin cycle.
The task
Visitors to the zoo in Nuremberg, Germany can experience
polar bears first-hand, even under water, because the bears’
living area includes a tank with a viewing window. In this
compound comprising 1,700 m2 in total with 600 m2 of
water surface area, 1200 m3 must be cleaned on a daily
basis. Keeping the viewing tank clean and clear throughout
requires an extremely effective water treatment process.
The tank must be cleaned to remove not only waste from
the bears, but also trash, leaves, and branches. In addition,
the extensive compound includes a waterfall and a waterjet fountain, which must also be operated.
Thus, the task was to implement a powerful, integrated,
and open speed control application that could adapt its
pumping performance precisely to the job at hand.
The solution
The MICROMASTER 420 frequency inverter scores points
here with two main performance features: A high output
frequency of up to 650 Hz in conjunction with the use of
asynchronous motors allows for drum speeds of up to
1100 rpm during the spin cycle. Factory-equipped lacquered electronic boards make the inverter extremely rugged, enabling it to withstand the constantly prevailing high
temperatures within the machine, the humidity, and the
accumulating dust. The manufacturer is highly satisfied
by the software-supported commissioning procedure with
“STARTER”, the menu-assisted commissioning tool: When
developing new washing machines and optimizing wash
programs, modified drive parameters can be loaded to the
inverter via the standard RS485 interface on an entirely individual basis. So the next time around, the laundry will be
washed clean with even more gentle care!
The solution
A centralized pump assembly comprising five pumps is
connected to the pipe system via automated valves and
gates. The MICROMASTER frequency inverter operates these
pumps with controlled speed. This is where the MICROMASTER 430 can really play up its strengths: gentle start-up
of the pumps prevents water surges in the pipe system. The
adjustment of speed enables efficient use of energy in the
partial load operational range, thus enabling cost-effective
operation.The drive technology is connected to a SIMATIC
S7 programmable logic controller via PROFIBUS DP. The
open, integrated automation technology, which extends
from the sensors and drives all the way to the controller, is
the highlight for the operator: with Totally Integrated Automation, he and his fellow employees have direct access to
everything, “from top to bottom”. And the polar bears and
visitors can enjoy the clear view!

MICROMASTER 440:
Frequency inverters improve process technology
in glass-fiber fleece production at Symalit
The task
Glass fiber fleeces are an important base material in the
production of high-strength molded-plastic components,
such as those used for automobile instrument panels or to
form wheel housing covers. A homogeneous structure of
these so-called composite boards is the number one objective of the production process.
For drive technology, the challenge is to provide an extremely refined control process.
The solution
To produce the fleece, capillary-sized glass fibers are unrolled from a bobbin and placed onto conveyor belts in a
continuous stream.
The vector control of the MICROMASTER 440 frequency
inverter operates the machine axes with precise speed control and ensures an optimal distribution of fibers. An addi-
tional speed sensor is located on the actual belt drive. This
signal feeback is evaluated by an optional module that can
be plugged onto the inverter and provides the advantages
of enabling the vector control of the inverter to operate
even more accurately and increasing the dynamic response
of the entire drive train.
In order to achieve the required long operating time of the
installations, important drive axes are equipped in a redundant configuration with MICROMASTER 440 and operated
alternately. Each time the equipment stops, the frequency
inverter switches over automatically, thus increasing the
overall production safety. During device replacement, the
“fine tuning” that has been achieved remains intact in the
parameters and is transferred to other devices by means
of a data interface or via a plug-on operator panel. Thanks
to drive control with MICROMASTER 440, targeted, precise
improvements in the production process can be made on a
continuous basis. And the tangible results can truly be felt
in the homogeneous weight distribution of each composite
board produced!
