Siemens 6SL3120-1TE32-0AA4: SINAMICS S120 Single Motor Module Guide

The Siemens 6SL3120-1TE32-0AA4 is a SINAMICS S120 Single Motor Module rated 32 A on a 600 V DC link. It is the axis-side power stage of a booksize drive system: the Line Module rectifies incoming AC into the common DC bus, and each Motor Module converts that DC into the controlled three-phase output for one motor.

Quick answer

Where it sits in a SINAMICS S120 system

A booksize line-up is built left to right:

1. Line Module (Smart or Active) feeds the DC bus.
2. Motor Modules clip onto the DC bus busbars — one module per axis.
3. A Control Unit runs the closed-loop control over DRIVE-CLiQ.
4. DRIVE-CLiQ cabling carries motor encoder and module identification data.

The 6SL3120-1TE32-0AA4 is the single-axis member of that line-up. For two smaller axes in the same width, Siemens uses Double Motor Modules instead; for one larger axis, you move up the current rating rather than paralleling modules.

How to size it correctly

• Match continuous current, not motor kW alone. Compare the motor rated current against the 32 A continuous rating, then confirm the overload profile your cycle demands.
• Check the DC link. The module expects a 600 V DC bus from a matched Line Module; feeding it from an unmatched supply is the most common commissioning failure.
• Add up the bus. The Line Module must cover the sum of simultaneous axis loads, not the largest axis.
• Plan cooling. Internal air cooling needs the specified free space above and below the module inside the cabinet.

Installation and commissioning checklist

• De-energise and verify the DC bus is fully discharged before touching busbars.
• Slide the module onto the DC link busbars and torque the connections to the Siemens-specified values.
• Chain DRIVE-CLiQ from the Control Unit through each module in a defined order — the topology is stored and compared at power-up.
• Connect the motor encoder through the corresponding DRIVE-CLiQ or sensor module.
• Commission with STARTER or TIA Portal / Startdrive, then save the parameter set to the memory card.

Common failure symptoms

• Repeated overcurrent trips — usually undersized module for the duty cycle, or a motor cable insulation fault.
• DRIVE-CLiQ topology error at power-up — a module was replaced or re-ordered without accepting the new topology.
• Overtemperature warnings — blocked cabinet airflow or clogged filters, not a failed module.
• Dead axis with a healthy Line Module — isolate by swapping the axis onto a known-good module before ordering parts.

Replacing a failed 6SL3120-1TE32-0AA4

Replace like for like where possible: keep the same current rating, the same DRIVE-CLiQ position and the same firmware family as the rest of the line-up. After swapping, accept the topology on the Control Unit and reload the saved parameter set so the axis returns with its original tuning.
