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.

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 © Siemens AG 2009 MICROMASTER References 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!
