Siemens SINAMICS S120 6SL3120-1TE24-5AA3 – Single Motor Module for high‑performance multi-axis motion

The Siemens 6SL3120-1TE24-5AA3 is a SINAMICS S120 Single Motor Module in booksize format, built for dynamic, multi-axis machines and high-duty continuous operation. It ties into a common DC bus with a Line Module and coordinates via DRIVE‑CLiQ, which, in practice, makes cabinet layouts cleaner and maintenance simpler. One thing I appreciate is how predictable it runs under cyclic loads—typically you get stable torque control and very smooth speed response when paired with a CU320‑2.

Key Features

• Booksize Single Motor Module (AA3 cooling) – Internal air cooling with integrated fan, ideal for compact panels.
• Common DC bus architecture – Powered from an S120 Line Module; simplifies multi‑axis sharing of regenerated energy.
• DRIVE‑CLiQ interface – Fast, deterministic system bus for connection to CU320‑2/CU310‑2 and sensor modules.
• High dynamic control – From my experience, it handles cyclic and positioning loads with very consistent torque accuracy.
• Scalable power – The “-1TE24-5” variant is typically used where ~45 A motor current is needed (duty class dependent).
• Global approvals – CE/UL-compliant design for export projects and multi-region deployments.

Technical Specifications

Application Fields

You’ll typically see this module in multi-axis packaging machines, material handling lines, CNC transfer systems, winders/unwinders, press feeders, and high-speed robotics/gantry axes. It pairs well where coordinated motion and energy sharing on a common DC bus improve efficiency, for example on machines with frequent acceleration/deceleration cycles.

Advantages & Value for Procurement

• Reliability – S120 booksize modules have proven field lifetimes; in many cases, fans are the only periodic wear item.
• Compatibility – Works seamlessly with CU320‑2, CU310‑2 (DP/PN), and Siemens sensor modules over DRIVE‑CLiQ.
• Cabinet efficiency – Common DC bus means fewer line-side components per axis and cleaner wiring, which usually cuts build time.
• Serviceability – Clear diagnostics via STARTER/Startdrive; spare parts availability is solid across regions.
• Total cost – Energy sharing on the DC bus can reduce braking losses; customers often see lower lifecycle costs on multi-axis machines.

Installation & Maintenance

• Panel environment – Mount vertically in a sealed cabinet (typically IP54 or better). Provide unobstructed top/bottom clearances and forced ventilation.
• Wiring – Use shielded motor cables, proper PE bonding, and adhere to Siemens EMC layout rules. DC bus bars/cables sized for rated current.
• Power chain – Feed via an S120 Line Module (Active or Basic). Include line-side protection, line reactor/harmonic mitigation as required by site.
• Safety – De-energize and discharge the DC link before servicing. Respect discharge times; verify absence of voltage.
• Routine care – Clean filters and heatsink air paths periodically. Check fan operation, retighten power terminals, and update firmware during planned shutdowns.
• Commissioning tips – Motor data optimization and encoder alignment (if used) typically save time and improve performance right away.

Quality & Certifications

• Conforms to CE; UL/cUL listed in the SINAMICS S120 system family
• RoHS compliant; manufactured under ISO 9001 quality systems
• Manufacturer warranty policy applies; our supply warranty: 365 days

Suggested Supporting Components

• CU320‑2 or CU310‑2 (DP/PN) Control Unit via DRIVE‑CLiQ
• Active Line Module or Basic Line Module (size matched) for DC bus supply
• SMC/SME/SMO sensor modules for encoder feedback, if required
• Line reactor, input protection, braking module/resistor (when application demands line‑side braking)

If you’re aligning this with an existing S120 platform, share the Line Module size, motor rating, and duty profile. It helps us verify that the 24‑5 variant is the right current class and that your cabinet cooling is sufficient.
