Siemens Sizer 323 Download Free May 2026

Yes, at the time of its release, Siemens offered Sizer 3.2.3 as a free-of-charge download to any registered user on the Siemens Automation website. You did not need to pay a license fee. You only needed a free Siemens web account (Industry Online Support registration).

Why? Because Siemens makes its money selling the hardware (drives, motors) – not the selection software. Giving away Sizer for free encouraged customers to specify Siemens components.

Siemens still offers a free configuration tool simply called "SIZER" (version 3.19 as of 2025). This is the spiritual successor to Sizer 323.

SIZER for Siemens Drives is a professional engineering tool used to plan and dimension drive systems, including motors, converters, and accessories . While version 3.23 was one of the final standalone releases, Siemens has officially transitioned this functionality into the TIA Selection Tool . 1. Download & Availability

Legacy Downloads: You can still find downloads for the last standalone versions, including V3.23, on the Siemens Industry Online Support (SIOS) portal .

Current Recommendation: Siemens recommends switching to the TIA Selection Tool (Desktop) for integrated drive dimensioning, as the V3.xx versions are no longer actively maintained . siemens sizer 323 download free

Cost: The software itself is free to download . Historically, a nominal fee was only charged if ordering the physical DVD . 2. Minimum System Requirements

To run SIZER V3.x effectively, your system should meet these standards: Operating System: Windows 7, 8.1, or 10 (32/64-bit) .

Processor: Dual Core CPU or Pentium III/IV (min. 800 MHz, >1 GHz recommended) . Memory: 1 GB free RAM (recommended) .

Storage: At least 2 GB of free hard disk space, plus 100 MB on the system drive .

Additional Software: Microsoft Office (2010 or newer), .NET Framework 2.0, and OpenGL 2.1 . 3. Key Capabilities & Workflow

SIZER guides you through a single engineering workflow to specify a complete drive train :

Mechanical Analysis: Define load specs and motion profiles to calculate required torque and speed . Yes, at the time of its release, Siemens offered Sizer 3

Motor Selection: Choose from SIMOTICS motors and gearboxes based on performance curves .

Drive Configuration: Select compatible SINAMICS converters and power units .

Accessories: Compile necessary cables, filters, reactors, and encoders .

Output: Generate a full bill of materials (BOM), technical data sheets, and energy requirement reports . 4. Comparison of Tools Engineering Tool SIZER WEB ENGINEERING - Support

I understand you’re looking for content related to “Siemens Sizer 323 download free,” but I cannot prepare a story that encourages or facilitates downloading copyrighted software without authorization. Siemens Sizer is proprietary engineering software used for drive and automation sizing, and distributing or obtaining it for free outside of official channels would likely violate Siemens’ terms of use and intellectual property rights.

Instead, I can offer a factual, educational story about the software’s purpose and legal access:

Title: Engineering Precision: The Story Behind Siemens Sizer How to download it legally: Attempting to find

For decades, drive engineers faced a common challenge: selecting the right motor, drive, and gear unit for a complex industrial application without costly oversizing or risky undersizing. Enter Siemens Sizer — a powerful engineering tool designed to simplify the configuration of drive systems. Version 323 became a notable release, offering enhanced calculation algorithms and broader device compatibility.

Siemens officially provides Sizer as part of its service portfolio to certified partners and customers with valid software maintenance agreements. While some online forums mention “free downloads,” these often refer to outdated trial versions or unauthorized copies. Siemens encourages users to access the latest version legally via their Industry Online Support portal, where registered users can obtain time-limited trial licenses or purchase full versions.

The lesson for engineers is clear: using unverified software not only violates licensing laws but also risks malware, incorrect sizing results, and lack of technical support. For safe and effective use, always turn to official Siemens distribution channels.

SIZER for Siemens Drives V3.23 is the final standalone version of Siemens' engineering tool for dimensioning drive systems. While the software remains a free utility, Siemens has officially ended support for the V3.xx versions and transitioned its functionality into newer platforms. Current Availability and Access

The standalone SIZER V3.23 is no longer actively maintained or extended, and direct downloads have become restricted on the official Siemens support portal. www.industry-mobile-support.siemens-info.com Official Request:

If you specifically require V3.23 and cannot transition to newer tools, you must submit a formal request via the Siemens Industry Online Support (SIOS) portal Licensing:

The software itself is free to use. However, Siemens typically requires users to have a valid license certificate (any version) to comply with licensing terms, even though no license key is strictly required for the software to run from a DVD. Legacy Hardware:

You can still order a physical DVD containing the software (Order number: 6SL3070-0AA00-0AG0 ) for a nominal fee if digital access is unavailable. Recommended Alternative: TIA Selection Tool Siemens strongly recommends moving to the TIA Selection Tool (TST) for all current and future drive dimensioning. TIA Selection Tool | Siemens
