Troubleshooting & Replacement Tips

Ten years on the floor taught me that most 6SL3120-1TE26-0AA3 failures fall into three buckets. Know which one you’re dealing with before you swap the module — otherwise you’ll kill the replacement too.

Fault A7xx / F7xxx — Overcurrent or Short Circuit: Before fitting the new module, megger the motor windings and check the power cable insulation. A shorted winding will take out the new module within seconds of enabling the drive. Resistance to ground should be >1 MΩ at 500 V DC. If it’s not, the motor is the root cause, not the module.

Fault F30001 / F30002 — DC Bus Undervoltage or Overvoltage: Check the Line Module (ALM or SLM) first. A failing capacitor bank in the line module will cause the motor module to trip repeatedly. Measure DC bus voltage at the module terminals — it should be stable within ±10% of nominal 600 V DC under load. Ripple above 5% indicates a line module or capacitor issue upstream.

DRIVE-CLiQ Communication Fault (A01900 / F01910): This is the most common misdiagnosis. The module itself is fine — the DRIVE-CLiQ cable or the CU320-2 port is the culprit. Swap the DRIVE-CLiQ cable first (6FX series). If the fault clears, you saved yourself a module replacement. If it persists, check the CU320-2 port for bent pins or corrosion.

Replacement Procedure — Critical Steps:

• Power down the entire drive line-up and discharge the DC bus. Wait a minimum of 5 minutes after power-off before touching any terminals. Measure DC bus voltage with a calibrated meter — it must read below 50 V before proceeding.
• Disconnect DRIVE-CLiQ, motor power cables (U2/V2/W2), and the DC bus bars (P600/M600) in that order. Label every cable before removal — the S120 booksize format packs connectors tightly and mistakes are easy.
• The 6SL3120-1TE26-0AA3 uses a slot-based booksize mounting rail. Slide the module out horizontally after releasing the locking lever. Do not force it — if it resists, check for a retained DC bus bar clip.
• Before inserting the replacement, inspect the DC bus bar contacts on the new module for any shipping damage. Fit the module onto the rail, reconnect DC bus bars first, then motor cables, then DRIVE-CLiQ last.
• Firmware matching: The replacement module will be auto-detected by the CU320-2 via DRIVE-CLiQ on first power-up. If the CU firmware version is below V4.7, the module may not be recognized. Check the CU firmware version in STARTER or Startdrive before commissioning. Upgrade if necessary — mismatched firmware is a silent killer that produces intermittent faults weeks after replacement.
• No DIP switches or rotary address switches on this module — the S120 booksize system uses automatic DRIVE-CLiQ topology detection. Address assignment is handled by the CU320-2 automatically on first boot after replacement. You do not need to manually set a node address.
• After power-up, run a motor identification (rotating or stationary) via STARTER/Startdrive to re-optimize the current controller parameters for your specific motor. Do not skip this step — the motor data stored in the old module is gone, and running without re-identification will result in poor dynamic performance or nuisance trips.

Reliability in Harsh Conditions

The 6SL3120-1TE26-0AA3 is built to Siemens’ SINAMICS S120 industrial grade specification — not consumer-grade electronics dressed up in an industrial enclosure. The internal power stage uses IGBT modules rated for continuous operation at 60 A with a thermal management system designed around the booksize forced-air cooling architecture. The module has been validated against IEC 61800-5-1 for electrical safety and IEC 61800-3 for EMC in industrial environments.

In practice, this means the module handles the conditions you actually work in: cabinet temperatures that spike to 45 °C during summer production runs, vibration from adjacent press lines transmitted through the mounting rail, and the voltage transients that come with heavy motor loads switching on and off the same bus. The conformal coating on the control PCB provides additional protection against humidity and condensation — relevant for food processing, coastal facilities, and any plant where the HVAC is unreliable.

Units in our Xiamen stock are stored in climate-controlled conditions (18–25 °C, RH <60%) in original Siemens packaging. We do not strip modules from donor machines or repackage loose units. What you receive is what Siemens shipped.
