Simocom U is the official configuration and commissioning software developed by Siemens specifically for the SIMOTICS TN series of geared motors (formerly known under the Loher brand). As industrial facilities move toward greater digitization, having the correct configuration tools is essential for engineers and maintenance personnel. This guide outlines what the software does, how to acquire it, and what to look for during the download process.
As a last resort, open a support ticket requesting the Simocom U installer for legacy drive maintenance. Provide your drive serial numbers to justify the request.
For safety and reliability, always source Simocom U directly from Siemens. Avoid "cracked" versions found on file-sharing sites, as these can corrupt sensitive compressor parameter data, leading to costly downtime.

Simocom U is a parameterization and commissioning software developed by Siemens for specific drive families, particularly the Micromaster series (MM420, MM430, MM440) and older Sinamics drives. Unlike the heavy TIA Portal, Simocom U is a lightweight tool designed for basic tasks:
Important Note: Simocom U is largely considered legacy software. For newer drives (Sinamics G120X, S210), Siemens recommends using STARTER or SINAMICS Startdrive integrated into TIA Portal. However, for legacy system maintenance, Simocom U remains invaluable.
