Siemens 6SL3120-1TE13-0AA3 SINAMICS S120 single motor module for industrial drive cabinets

Evidence-backed system role for 6SL3120-1TE13-0AA3, a documented SINAMICS S120 single motor module rated at 3 A.

Documented module function

Rebuilt from individual evidence

Siemens documents 6SL3120-1TE13-0AA3 as a single motor module in the SINAMICS S120 booksize Motor Modules family.

The documented variant is rated at 3 A and uses internal air cooling; these values identify the power-stage variant to match against the installed cabinet.

In the system, it sits between the shared DC link and the connected motor axis, where its Motor Module role supports controlled motion power.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Drives the connected motor axis as a SINAMICS S120 power stage.
System position: Sits between the shared SINAMICS S120 DC link and the connected motor axis in the drive cabinet.
Upstream / inputs: Receives DC-link energy and motion commands from the upstream SINAMICS S120 control path.
Downstream / outputs: Sends switched three-phase motor power to the connected motor axis.
Limitations: Unknown: installed topology, firmware compatibility, wiring, and unit condition.
