Siemens 6SL3121-1TE24-5AA3 SINAMICS S120 45 A Single Motor Module
A 45 A external-air-cooled power stage for one SINAMICS S120 axis, kept distinct from the adjacent TE23 and TE26 current classes.
Product Overview
Siemens 6SL3121-1TE24-5AA3 is a SINAMICS S120 Single Motor Module for one motor axis. The booksize unit accepts the 600 V DC input class and supplies a 400 V three-phase output rated at 45 A. It uses external air cooling, includes a DRIVE-CLiQ cable and supports optimized pulse patterns together with extended Safety Integrated functions. Siemens lists the product in the cancellation lifecycle phase.
Performance
- Provides a 45 A rated output for one controlled motor axis.
- Converts power from the SINAMICS common DC link to a three-phase motor output.
- Uses external air cooling to manage power-stage losses.
- Coordinates with the drive system through DRIVE-CLiQ.
- Supports the optimized pulse-pattern functions of the documented generation.
- Works with extended Safety Integrated functions when configured in the complete system.

FAQ
What current class identifies 6SL3121-1TE24-5AA3?
The official product description identifies a 45 A motor output.
Is this a single-axis or double-axis module?
It is a Single Motor Module for one motor axis.
Why is external cooling important during replacement?
The cabinet opening and airflow path are part of the thermal design and must match the installed module arrangement.
Can a TE23 or TE26 module be selected only because the suffix is similar?
No. TE23, TE24-5 and TE26 represent different current classes and may have different mechanical and system requirements.
What lifecycle phase is shown by Siemens?
The exact official record identifies the product in the cancellation phase.
Which project data should be available before a service exchange?
Retain the motor and encoder data, DRIVE-CLiQ topology, control settings, safety parameters and approved wiring drawings.
