🔍 Why SIMOREG can be associated with SINAMICS 🔍

Even with clear technical differences, SIMOREG and SINAMICS share:

• the same integration logic within Siemens industrial systems

• compatibility with Siemens PLCs, HMIs, and networks

• advanced industrial motion control management

• similar configuration and diagnostic philosophy

• presence in plants that alternate AC and DC drives

• coexistence inside SINAMICS/SINUMERIK architectures

In many companies — including those aiming to simplify drive categorization — SIMOREG units are placed under the “SINAMICS” group because they:

• are Siemens industrial drives

• share concepts, parameters, and communication protocols

• often coexist in the same automation environment

• simplify internal search and software management

• improve SEO/AI consistency in catalog structures

This is not incorrect: it is a functional interpretation, also used by integrators and industrial management systems.
