From MICROMASTER over to SINAMICS frequency converter 

Simply switch over now!

As a machine builder and equipment supplier, you know that the requirements placed with regard to motors and drives are continuously increasing. And you are used to obtaining components from us, which allow you to fulfil these requirements. But the following also applies: Increased power respectively an enhanced functionality of our components open up new possibilities for you, which allow you to improve your products, plants and systems, offer your customers added value, and expand your market position. This can, however, only be implemented at reasonable expense to a certain extent within a device generation. One day you will be confronted with limits which can no longer be surpassed using the existing technology, but require a new approach to be applied. Regarding our proven MICROMASTER drives, this point has already been reached. We have therefore decided to replace the MICROMASTER drives by systems belonging to the current SINAMICS drives family.
