The is the final release of the standalone SIZER V3.xx dimensioning software. Siemens has transitioned its drive system dimensioning functions to the TIA Selection Tool (desktop version) and no longer provides feature updates for the standalone SIZER V3 series. Download and Availability

Analyze energy consumption and suggest energy-saving configurations.

A: SIZER is specifically designed for configuring and sizing drive systems (motors, controllers, gears). The TIA Selection Tool is a broader tool that covers all automation components, including controllers (PLCs), I/O systems, HMIs, and more. They are complementary and can exchange data to create a complete solution.

✅ Accurate short-circuit and load flow calculations ✅ Seamless selection of circuit breakers, contactors, and motor starters ✅ Generates professional documentation and bill of materials (BOM) ✅ Supports global standards (IEC 60947, UL 508, etc.)

Choose the appropriate SINAMICS drive topology (e.g., single-motor drive like G120 or multi-motor system like S120). The software will calculate the required continuous and peak currents. Step 5: Export Project Results

Siemens Sizer 3.23 remains a reliable, powerful, and necessary tool for engineers working with legacy Siemens drives or those who require an offline solution without internet dependency. By following the download sources provided in this article—specifically the Siemens support portal or the community repositories—you can safely obtain the software.

This guide provides a comprehensive overview of Siemens SIZER 3.23, including its capabilities, its place within the Siemens portfolio, and the proper procedure for downloading and installing the tool. What is Siemens SIZER for Siemens Drives?

If you cannot obtain the official version

Remember that the configuration file generated by SIZER can be imported directly into Siemens STARTER or TIA Portal. This eliminates the need to manually re-enter motor codes and drive parameters when commissioning the physical hardware.

Version 3.23 is known for its stability on older Windows environments and low system resource consumption.
