2. SINAMICS STARTER / STARTDRIVE

If your goal is to commission drives rather than size mechanical components, you might actually need different software:

STARTER: Often available as a free download for basic commissioning of SINAMICS drives (requires a TIA Portal license for full integration or works standalone for basic setup).
STARTDRIVE: Integrated into TIA Portal. While not free, many automation engineers already have access to this via their company’s TIA Portal licenses.

How to Use Siemens Sizer 323 – A Quick Example

To understand why this tool is invaluable, here’s a typical workflow:

Create New Project → File → New → Name it “Conveyor_Project”.
Select Application → Choose “Conveyor belt” from the library.
Enter Mechanical Data → Load torque (Nm), speed (rpm), inertia (kg·m²).
Select Motor Type → SIMOTICS S-1FK7 servo or standard induction motor.
Select Drive → SINAMICS S120, G120, or older Micromaster 440.
Run Sizing → Click “Calculate”. The tool checks thermal limits, overload capacity, and braking requirements.
View Report → Sizer generates a PDF with electrical data, order numbers, and energy efficiency hints.

This entire process takes less than 5 minutes for a simple system, saving hours of manual calculation. STARTER: Often available as a free download for

1. The Software: What is Siemens SIZER?

Siemens SIZER is a professional-grade engineering tool used to calculate and configure drive components (motors, converters, couplings, and gearboxes). It is widely used in the automation industry to ensure machinery is neither underpowered nor inefficiently overpowered.

Functionality: It calculates load cycles, energy efficiency, and dynamic performance.
Target Audience: Electrical engineers, system integrators, and automation professionals.
Complexity: This is not a consumer-grade app; it requires specific domain knowledge to operate effectively.

Q4: Can I configure a 2024 Sinamics G220 drive with Sizer 323?

A: No. Sizer 323's catalog stopped updating around 2012. You need SIZER V3.19 or TIA Selection Tool.
