MICROMASTER Frequency Inverters

A vast number of today’s motor applications require the use of a Variable Speed Drive to ensure optimum performance. Making the correct speed adjustments can ensure dramatic savings in energy costs and improvements in application performance. From the technology available, which unit should you select to ensure these goals are met and your investment pays off?

As a supplier of complete drive systems and technology, Siemens can offer you a wide range of frequency inverters: the MICROMASTER family. Thanks to their modular design, all the inverter units can be used in a variety of applications and are extremely flexible in use. With power ratings ranging from 0.12 to 250 kW (0.16 to 300 HP), they can readily be adapted to new requirements without any great effort.

Our frequency inverters combine the highest technical quality with versatile functionality: from the basic MICROMASTER 410 for simple applications to the high-performance MICROMASTER 440 with sensorless vector control and a power range up to 250 kW (300 HP). Each individual member of our MICROMASTER family is characterized by its exceptionally simple handling: from installation and commissioning to operator control. Later adaptation to new requirements is simplicity itself.
Each frequency inverter belonging to the family allows flexible circuit connection of inputs and outputs for optimum link-up of a broad variety of digital and analog signals. With its default factory settings, it is immediately ready for use.

Part of Totally Integrated Automation (TIA)

All standard Siemens drives with the PROFIBUS option are integrated in TIA. On the basis of TIA’s three-pronged universality with regard to communication, configuration and data management, our drive systems perform automation tasks smoothly and efficiently, with a savings potential of up to 30 %.

Safe operation – all over the world

All the important protection and overload functions are already standard features of our inverters. And the requirements of the EU low-voltage directive are met by all the devices in the MICROMASTER family. They have the CE label, as well as both UL and CUL certification.
