You generally do not need external cooling units for this specific module, provided your cabinet maintains the ambient temperature requirements (usually below 40°C/104°F without derating).

DRIVE-CLiQ Interface and Connectivity

Siemens simplified the wiring mess with the DRIVE-CLiQ interface. The 6SL3120-2TE13-0AA4 comes equipped with 3 DRIVE-CLiQ sockets. These RJ45-style ports allow for automatic topology recognition and easy daisy-chaining to the Control Unit (CU320-2) or Motor Modules. This digital connection is robust against electrical noise, ensuring your encoder data and control signals remain clean.

System Compatibility and Integration

Getting the 6SL3120-2TE13-0AA4 up and running within an existing automation lineup is straightforward, provided you understand the architecture. This SINAMICS S120 Double Motor Module is designed to sit neatly in a multi-axis booksize configuration, relying on a central control unit to manage logic and motion profiles.

Connecting to the CU320-2 Control Unit

The module interfaces directly with the CU320-2 Control Unit via the DRIVE-CLiQ system. This digital interface is a game-changer for setup; it automatically detects the Booksize Motor Module 3A, pulling the electronic rating plate data without the need for manual parameter entry. It streamlines the commissioning process significantly. For those building out complex control cabinets, integrating reliable high-quality Siemens PLC module factory solutions alongside these drives ensures seamless communication across the entire machine architecture.

Compatible Siemens Servo Motors

Regarding the load, this Double axis servo drive Siemens unit is optimized for specific synchronous motors. With a 3A output per axis, it isn’t meant for heavy-duty lifting but rather for precision tasks. It pairs perfectly with:

  • 1FK7 Series: The standard choice for general motion control applications.

Replacing the Older 6SL3120-2TE13-0AA3

If you are looking for a Siemens servo drive replacement for the legacy 6SL3120-2TE13-0AA3, the -0AA4 version is the official 6SL3120-2TE13-0AA3 successor. It is fully compatible as a spare part. You can swap the older unit for this newer 6SL31202TE130AA4 without changing the mounting points or the motor cabling. The internal air cooling design remains consistent, making maintenance downtime minimal during the transition.

Installation and Setup Requirements

Getting the 6sl3120-2te13-0aa4 up and running requires attention to detail. Since this is a SINAMICS booksize power unit, the physical and electrical integration must follow strict guidelines to ensure the system handles the 3A/3A output reliably without faulting.

DC Link Busbars and Terminal Adapters

The Siemens S120 Double Motor Module relies on the integrated DC link busbar system for power distribution. You cannot simply wire these loosely; the red and black busbars must be slid into place and tightened to the correct torque specifications to ensure continuity across the drive lineup.

  • Busbars: Ensure the module is mounted flush with adjacent units so the DC link bridges connect perfectly.
  • 24V Supply: You must use the 24V terminal adapter to feed the electronics power supply; this is often overlooked during rough-in.
  • Safety: Always reinstall the red plastic covers over the busbars immediately after tightening to prevent accidental contact.

Proper Motor Cable Shielding for EMC

In US industrial facilities, signal noise can be a nightmare. To keep the Double axis servo drive Siemens from interfering with sensitive sensors or controllers, proper shielding is non-negotiable. You need to ground the motor cable shields right at the module using the dedicated shield connection plate. A 360-degree bond on the shield clamp is required to divert high-frequency noise effectively.

Minimum Firmware Versions for Operation

Before powering up, check your Control Unit. This module communicates via DRIVE-CLiQ and requires compatible firmware to be recognized. If you are using an older CU320, you might need an update.

Component Requirement
Control Unit CU320-2 DP or CU320-2 PN
Firmware Version Generally V4.5 or higher (Verify with specific project files)
Topology Automatic recognition via DRIVE-CLiQ

Ensuring your firmware matches the hardware revision of the 6sl3120-2te13-0aa4 prevents “Topology Error” faults during the initial commissioning phase.

Frequently Asked Questions (FAQ)

When managing a Siemens S120 Double Motor Module installation, a few common questions always pop up regarding compatibility and configuration. Here are the answers to the most frequent inquiries we receive about the 6SL3120-2TE13-0AA4.

Can I replace the -0AA3 version with this module?

Yes, absolutely. The 6SL3120-2TE13-0AA4 is the direct 6SL3120-2TE13-0AA3 successor. Siemens designed this iteration to be fully backward compatible with the older version. In most applications, you can swap the hardware without needing to completely reconfigure your drive project. The Control Unit (CU320-2) generally recognizes the new module automatically via the DRIVE-CLiQ interface, making the transition seamless for maintenance teams.

Does the 6SL3120-2TE13-0AA4 need an external fan?

No, this specific booksize unit features Internal air cooling. It comes equipped with its own integrated fan assembly designed to manage the thermal load of the 3A/3A output. You do not need to mount an external fan module directly to the drive. However, always ensure your electrical cabinet has sufficient ventilation to handle the heat dissipation from the drive lineup.

What are the pulse frequency settings?

The rated pulse frequency for this SINAMICS S120 3A/3A drive is 4 kHz. At this frequency, the module delivers its full rated output current. While the system allows for higher pulse frequencies to reduce motor noise or improve waveform quality when driving precision servos like the Kuka 1FK7034-5AZ91-1ZZ9-Z motor, you must account for current derating. Increasing the frequency above 4 kHz will reduce the available output current, so check the derating curves in the 6SL3120-2TE13-0AA4 datasheet before making adjustments.
