The 6SL3120-1TE23-0AA4 is a single motor module from the Siemens SINAMICS S120 booksize drive family. It converts the shared DC link voltage into a controlled three-phase output for one servo or induction motor. If your machine is down and this part number is on the failed unit, this guide gives you the key specs, the faults we see most often in our repair lab, and a clear way to decide between a replacement unit and a repair.
What Is the 6SL3120-1TE23-0AA4?
Within a SINAMICS S120 multi-axis system, a line module feeds a common DC bus, and several motor modules hang on that bus. The 6SL3120-1TE23-0AA4 is one of those motor modules, in booksize format with internal air cooling. It works together with a Control Unit (typically a CU320-2) over DRIVE-CLiQ, which handles closed-loop control, diagnostics, and parameter storage. Because the parameters live in the Control Unit and its CF card, swapping this Siemens drive module is usually a mechanical and wiring job, not a re-commissioning job. That is good news when downtime is expensive.

Always confirm the full rating plate against your motor nameplate. Current rating, not just part number prefix, decides compatibility.
Common Faults We See on This Module
In our repair lab, the 6SL3120-1TE23-0AA4 comes in with a small set of repeat failures. Knowing them helps you judge whether the module itself is bad or the problem is upstream.
- F30001 overcurrent. The most common trip. Root causes range from a shorted motor cable to a degraded IGBT stage inside the module. If the fault returns immediately after reset with the motor disconnected, the power stage is usually damaged. For a structured diagnostic path, see our guide on troubleshooting overcurrent and overload alarms.
- F30002 / F30003 DC link overvoltage or undervoltage. Often caused by the line module or mains supply, not the motor module. Check the whole drive line-up before condemning one module.
- F30004 heatsink overtemperature. Blocked air filters, a failed internal fan, or a cabinet running hot. The fan is a wear part on booksize modules and we replace it often.
- DRIVE-CLiQ communication faults (F01910 series). Sometimes just a damaged cable or dirty connector, sometimes a failed interface board on the module.
- Dead power stage, no fault code. Burnt IGBTs or driver circuits after a phase-to-phase short in the motor cable. This is a classic repair case.
Compatibility and Alternative Models
The 6SL3120-1TE23-0AA4 has an older hardware revision, the 6SL3120-1TE23-0AA3, which is electrically equivalent for most applications [需核实]. Modules in the same frame share mounting and DC link adapters, but current ratings differ. A smaller module such as the 6SL3120-1TE21-8AA3 single motor module only works if your motor’s rated current stays within its lower limit. Never fit a higher-current module without checking motor protection parameters on the Control Unit. If you run two small axes, a SINAMICS S120 double motor module can consolidate space, but that is a redesign, not a swap.

New vs Used vs Repair: How to Choose
For this module you have three realistic options:
- New from the factory channel. Full price and sometimes long lead time. Reasonable for planned upgrades, painful for emergency breakdowns.
- Tested used or refurbished stock. Fast and cost-effective when the unit is functionally verified. Every 6SL3120-1TE23-0AA4 we ship is bench-tested before packing, and we hold stock on the S120 booksize range.
- Repair your failed unit. IGBT stage, fan, and interface board repairs are routine for this series. Standard repair turnaround is 3–5 days with a 1-year warranty, and repair typically saves up to 75% versus buying new. If you are weighing this choice on older hardware, read our notes on repair, refurbish, or replace decisions.
FAQ
Is the 6SL3120-1TE23-0AA4 discontinued?
The S120 booksize platform remains an active Siemens drive family, but individual hardware revisions move in and out of availability. When a revision is scarce, tested used stock or repair keeps your line running without redesign.
Can I swap the module without re-commissioning?
In most cases, yes. Parameters live on the Control Unit’s CF card. Replace the module, reconnect DRIVE-CLiQ and power wiring, then power up and confirm the topology recognition.
What does F30001 mean on a SINAMICS S120?
F30001 is an overcurrent fault on the power unit. Disconnect the motor, megger the cable and motor windings, then re-test. A trip that persists with the motor disconnected points to the module’s power stage.
How fast can I get a replacement 6SL3120-1TE23-0AA4?
In-stock units ship within 48 hours via DHL with tracking. Repairs run 3–5 days as standard.
