03Features

Key Functions

  • Controls two motor axes from one booksize Motor Module.
  • Each output channel carries the documented 9 A rating.
  • Optimized pulse patterns are included in this hardware revision.
  • DRIVE-CLiQ connects the module into the S120 control topology.
  • Internal air cooling supports compact multi-axis cabinet construction.
  • Extended Safety Integrated functions require the appropriate Control Unit, firmware and validated safety configuration.

Product Identity

  • Manufacturer: Siemens
  • Model: 6SL3120-2TE21-0AA3
  • Product Type: SINAMICS S120 Double Motor Module, Booksize

04Compatibility

  • Confirm the 600 V DC-link system, busbars, Control Unit, firmware and DRIVE-CLiQ topology.
  • Match motor ratings, encoder systems, motor cables, braking arrangements and axis-specific commissioning data.
  • Verify the approved safety functions and licenses for the installed S120 release.
  • Check mechanical width, cooling path, clearances, ambient temperature and cabinet design.
  • The later 6SL3120-2TE21-0AA4 has the same core 9 A / 9 A product description, but a revision change still requires Siemens compatibility confirmation.

05Replacement & Lifecycle

  • The current Siemens listing states that 6SL3120-2TE21-0AA3 is no longer available.
  • Evaluate 6SL3120-2TE21-0AA4 only through the current Siemens replacement and compatibility documentation.
  • Back up the complete drive project and record Control Unit firmware, axis assignments, motor and encoder data, safety settings and DRIVE-CLiQ addresses.
  • Do not assume that identical current ratings guarantee firmware, pulse-pattern or Safety Integrated compatibility.
  • After replacement, commission and test both axes, feedback, current limits, brakes, safety functions, alarms and thermal performance.

06Applications

Typical Uses

  • Dual-axis S120 machine sections requiring 9 A per output channel.
  • Multi-axis packaging, handling, printing and converting machinery.
  • Maintenance of existing booksize drive groups using internal air cooling.
  • Engineered replacement projects where the installed AA3 revision is no longer available.

Selection Boundary

  • Confirm the exact AA3 revision and existing system release.
  • Match both 9 A axes, motors, encoders and the 600 V DC link.
  • Use Siemens compatibility guidance before moving to AA4 or another module.

FAQFrequently Asked Questions

What is Siemens 6SL3120-2TE21-0AA3?
