: It calculates necessary torque, speed, and power based on load profiles and recommends compatible motors, converters, and accessories.

The tool is also referred to as the "SIZER for Siemens Drives" engineering tool and is officially available through Siemens with order number . SIZER is available in both German and English interfaces.

Finding the right drive configuration requires precise calculations. Siemens SIZER is the official engineering tool designed to simplify this process. It helps users select and configure correct motor, drive, and accessory combinations.

Automatically matching power units, motors, cables, and line filters.

Make full use of SIZER's documentation capabilities. The tool produces:

Are you looking to size a specific (like SINAMICS S120 or G120)?

: SIZER evaluates thermal limits to pick SIMOTICS motors.

: If you specifically require the legacy V3.23 version and cannot migrate to the TIA Selection Tool , Siemens advises submitting a formal support request through their portal.

: While "323" likely refers to Version 3.23 , Siemens frequently updates this tool to include new hardware and firmware support.

If you see error messages about missing files during installation, the Data2.cab file from the CAD package may be missing. This issue is common with older SIZER versions.

: It automatically generates bills of materials, data sheets, and order numbers, which significantly reduces manual engineering time and potential errors.

A: The main installation file is approximately 700-701 MB. The CAD package adds additional size if installed.

The (specifically version V3.23 ) is the final standalone release of Siemens' engineering tool for dimensioning drive systems. While it is no longer actively maintained, it remains a critical legacy tool for engineers working with SINAMICS, MICROMASTER, and SIMOTION systems. Overview of Siemens SIZER 3.23

Version 3.23 is part of the legacy V3.xx branch, known for its extensive, function-based approach that guides users through configuring both simple single drives and complex, multi-axis motion control applications. Key Capabilities of SIZER:

: You will need to create a free Siemens account. Because the software is subject to export control restrictions, your account may take a day or two to be verified before the download link becomes active.

By securing an "extra quality" version of Sizer 323, you ensure your legacy drives run at peak efficiency without the risk of corrupted software crashing your configuration mid-project.

Because Siemens has deprecated this software, you will not find it on the official Siemens Industry Mall for public download (you will only find Sizer 2007 or newer). Here is the safest approach to acquiring the file.
