Product Precautions
- Siemens 6SL3120-1TE24-5AA3 is a 45 A SINAMICS S120 booksize Single Motor Module. It draws from the common DC link and supplies a controlled three-phase output to one motor axis.
Module type: Single Motor Module
Rated output current: 45 A; base-load current 38 A
Cooling: Internal air; booksize construction
Rated output current: 45 A; base-load current 38 A
Cooling: Internal air; booksize construction
The Siemens NC 82 catalogue lists a 510-720 V DC-link range, 24 kW typical asynchronous-motor rating at a 600 V link, 60 A S6 current for 40% duty and 85 A maximum current. These values belong to their stated operating conditions; confirm the installed duty cycle and control settings rather than selecting by peak current alone.
The motor connection uses X1 U2/V2/W2 with M6 screw studs and a separate M6 protective-earth point. X11 supplies a 24 V DC, 2 A motor-brake interface. Check terminal hardware, conductor sizing, brake wiring and the machine safety sequence against the approved cabinet drawing.
Internal air cooling requires an unobstructed flow path. The published maximum power loss is 460 W and cooling-air demand is 0.031 m3/s; cabinet thermal assessment must account for the actual load and ambient conditions. The IP20 module also depends on the enclosure for touch protection and environmental shielding.

-
Single-axis motor drive
Use within a documented S120 cabinet where one motor axis is assigned to a 45 A Single Motor Module. Verify motor and drive data before enabling the axis. -
Shared DC-link assembly
Coordinate the module with the S120 line module and common DC-link busbars. Check 24 V electronics supply and permitted busbar loading in the whole lineup. -
Motor-brake integration
Use the X11 brake circuit only after matching the 24 V, 2 A interface and the brake coil, suppression and machine safety sequence. -
Service replacement
Keep full order code, axis project, safety settings and motor wiring together. Commission the replacement with controlled low-risk motion and fault-log review.
Prepare 6SL3120-1TE24-5AA3 as a high-energy S120 motor module. Coordinate electrical isolation, cabinet cooling and axis-project verification before commissioning.
Isolate and discharge the DC link
Follow Siemens and site lockout procedures; verify discharge at the specified points before touching power terminals.
Check busbar and supply fit
Confirm DC-link voltage, busbar ratings and 24 V electronics supply for the existing S120 cabinet.
Preserve cabinet cooling
Inspect fan operation, flow paths and ambient conditions before applying load; do not obstruct the internally cooled module.
Match motor and brake wiring
Verify U2/V2/W2, PE and X11 brake connections against the approved drawings and motor data.
Review cable and EMC design
Check shield termination, grounding and cable length; published maxima depend on the selected motor-cable system.
Commission under controlled motion
Restore the approved parameter and safety project, then test axis direction, feedback, braking and fault behavior before production release.

Technical notes
Drive integration: Confirm the 45 A Single Motor Module arrangement, DC-link supply, motor connection and cooling against the approved S120 cabinet design.
Acceptance: Preserve the axis project, safety configuration and motor data before replacement; verify PE, shield and fan operation before controlled start.

FAQ View All FAQ
-
How should 6SL3120-1TE24-5AA3 be assessed before replacing a Motor Module in an S120 lineup?Compare the complete order number, module topology, DC-link arrangement, control wiring and installed firmware/safety configuration. Confirm the replacement is approved for the existing Control Unit and machine project before energizing.
-
What can cause 6SL3120-1TE24-5AA3 to trip during acceleration even when the continuous current rating appears sufficient?Compare the drive trace with the base-load, S6 and peak-current limits under the actual duty cycle. Check motor load, current limits, ramp settings and cooling before attributing a trip to the module.
-
How should cabinet cooling be checked for 6SL3120-1TE24-5AA3 at rated load?Use the manufacturer maximum power-loss and air-flow values to review the cabinet thermal design. Inspect fan operation, unobstructed inlet and outlet paths, and ambient temperature with the drive operating at representative load.
-
Why should motor cable length be reviewed when integrating 6SL3120-1TE24-5AA3?The published 100 m shielded and 150 m unshielded maxima are conditional. Compare actual cable type, length, motor insulation and EMC installation; determine whether reactors or filters are required by the applicable Siemens system guide.
-
How should a technician verify the DC-link supply before commissioning 6SL3120-1TE24-5AA3?Confirm the system is isolated for wiring work, then follow the S120 startup procedure to check the DC-link range and 24 V electronics supply at the specified test points. Do not treat a nominal 600 V label as permission to bypass discharge checks.
-
When is a 24 V motor-brake circuit compatible with 6SL3120-1TE24-5AA3?Check the X11 brake connection against the documented 24 V DC, 2 A interface and the motor brake coil, suppression and timing requirements. Verify the machine safety sequence before releasing the axis.
-
How can grounding faults affect 6SL3120-1TE24-5AA3 after a replacement?Inspect the M6 protective-earth connection and shield termination. Compare the new wiring with the approved cabinet drawing and test the drive under representative motor current for EMC or earth-fault symptoms.
-
What acceptance evidence should be retained after 6SL3120-1TE24-5AA3 is exchanged?Record the original and replacement complete markings, wiring and PE checks, DC-link and 24 V readings, cooling condition, safety configuration and a controlled axis test with fault history.
