Siemens 6SL3126-2TE15-0AA4 SINAMICS S120 Double Motor Module
A two-axis SINAMICS S120 power module that combines AA4 hardware, compact booksize construction and a shared cold-plate heat path.
Product Overview
6SL3126-2TE15-0AA4 provides two controlled motor channels in one SINAMICS S120 booksize component. It connects both axes to the common DC link and DRIVE-CLiQ topology while transferring heat through the machine cold plate. The exact double-motor designation is essential when planning wiring, thermal capacity and spare replacement.
Performance
- Supplies two regulated motor outputs from one modular power component.
- Uses optimized pulse patterns for coordinated motion applications.
- Carries topology and diagnostic information for both channels over DRIVE-CLiQ.
- Supports Extended Safety Integrated functions when configured in the complete machine.
- Consolidates two low-current axes while preserving separate motor and encoder parameter sets.

System Integration
- Confirm that the project expects a Double Motor Module and contains two correctly assigned axis objects.
- Prepare the specified cold-plate surface and verify the heat-removal capacity for simultaneous axis loading.
- Connect the common DC link, protective earth, both motors and signal interfaces according to the S120 manual.
- Restore each motor, encoder and safety parameter set to the correct channel.
- Commission and test the two axes individually before coordinated machine movement.
Applications
- Compact dual-axis servo groups in modular production machinery.
- Cold-plate machine designs that remove drive heat through a shared structure.
- Exact AA4 spare replacement for an installed two-channel S120 module.
- Motion systems where two low-current axes benefit from a consolidated power component.
- Service work that restores an archived DRIVE-CLiQ topology after planned shutdown.
FAQ
How many motor channels are provided by 6SL3126-2TE15-0AA4?
It is a Double Motor Module with two controlled outputs.
Why must both axis records be saved before replacement?
Each output has its own motor, encoder and operating parameters even though the hardware is shared.
What cooling interface is required for this exact article?
It uses cold-plate cooling and must be mounted to the engineered thermal surface.
Does the module participate in DRIVE-CLiQ topology?
Yes. Siemens includes the DRIVE-CLiQ cable and uses the interface for coordinated control and diagnostics.
What is the key suffix to retain in purchasing records?
Keep the full AA4 order number; similar current classes and cooling variants are separate articles.
How should two-axis commissioning be sequenced?
Verify wiring and cooling first, then test each axis independently before synchronized operation.
