Siemens 6SL3121-1TE26-0AA3 SINAMICS S120 Single Motor Module
An external-air-cooled SINAMICS S120 power stage engineered for one motor axis in the TE26 class.
Technical Summary
This AA3 Single Motor Module is a spare-part generation within the SINAMICS S120 booksize platform. It converts energy from the common DC link for one controlled motor and communicates with the coordinated drive system through DRIVE-CLiQ. Its external cooling path and validated safety configuration are part of the installed machine design.

Features
- Controls one motor axis from the common SINAMICS S120 DC-link system.
- Uses optimized pulse patterns for the documented hardware generation.
- Moves the principal heat path outside the cabinet through the external-cooling arrangement.
- Integrates status, control and topology data through DRIVE-CLiQ.
- Participates in engineered drive safety functions when configured in the complete project.
Compatibility
- Match the complete AA3 suffix, not only the TE26 power-class code.
- Confirm the cabinet cutout and external airflow arrangement before mechanical replacement.
- Check the control unit, firmware, motor data and DRIVE-CLiQ topology in the project archive.
- Keep the protective-earth and motor-connection design consistent with the approved electrical drawings.
- Validate every Safety Integrated function after hardware or project changes.
Replacement
- Siemens lists this exact order number in the product-cancellation phase.
- Retain the rating-plate data and a verified drive-project backup before removal.
- Do not use the earlier AA0 module as evidence for AA3 connector or project compatibility.
- Inspect the fan path and cabinet seals while the axis is isolated.
- Commission the replacement with electrical, direction-of-rotation and safety-function tests.
FAQ
What does the AA3 suffix identify?
It identifies the exact hardware generation and must remain part of the replacement check.
Why must the external cooling path be inspected?
The module relies on the cabinet interface and fan path to remove power-stage heat as engineered.
Is matching the TE26 code alone sufficient?
No. The full order number, interfaces, project data and safety configuration must all be reviewed.
What information should be backed up before exchange?
Preserve the SINAMICS project, motor data, encoder settings, topology and safety parameters.
How does Siemens classify the lifecycle?
The exact official product record shows the product-cancellation phase and treats the unit as a spare part.
Which checks complete a controlled replacement?
Confirm wiring, cooling, motor direction, drive diagnostics and every validated safety function.
