Type cancellation of MICROMASTER 4 drives family, including options, selected accessories and spares, effective Oct 1st, 2019

Due to its superior functionality, comprehensive performance  and flexibility, MICROMASTER 4  has been for many years a very successful drive system for single motor applications performed on production machines, in general machine building and multiple industry sectors.

We aim at continuing this unique success story with the new SINAMICS drive family. The SINAMICS drive system provides extended modularity and functionality, such as Safety Integrated functions, PROFINET communication interface, energy saving topologies, enhanced power range and much more.

As already announced on September 30th, 2017  the new part business of MICROMASTER 4 will close on September 30th, 2019 and the active marketing of MICROMASTER 4 will expire as well.

Effective October 1st, 2019 the type cancellation of MICROMASTER 4 becomes effective.

After this date you have access to our spare parts service and service support including extensive repair and service support offerings. Thus, we want to ensure availability of the drive systems installed in the field.

In addition we submit through our “Drive System Retrofit for MICROMASTER” the extension of the lifecycle of your machine. Thus, we want to offer a sufficient level of investment security for your company.

Swop over from MICROMASTER to SINAMICS drive family and continuously benefit from guaranteed spare part provision.

Drive System Retrofit for MICROMASTER

The final product discontinuation is scheduled for October 1st, 2027. After this date the product family will be completely discontinued.

We are confident that, on the one hand, we can offer you a sufficient level of investment security for the equipment of your machines to ensure appropriate support for the drives installed in the field, and, on the other hand, we can offer you with the new SINAMICS drive system an innovative successor product.

Support for the swop over to SINAMICS can be found on the MICROMASTER Internet homepage.
