Siemens 6SL3120-1TE26-0AC0 S120 Single Motor Module 60A

Product Overview

Siemens 6SL3120-1TE26-0AC0 S120 Single Motor Module 60A: Seamless Replacement & Upgrade Solution

The Siemens 6SL3120-1TE26-0AC0 is a SINAMICS S120 Single Motor Module rated at 60 A in Booksize format, designed for high-performance servo and vector drive applications across manufacturing, machine tool, printing, packaging, and process automation industries. As legacy MASTERDRIVES MC and SIMODRIVE 611 systems reach end-of-life, plant engineers and procurement teams are increasingly migrating to the SINAMICS S120 platform — and the 6SL3120-1TE26-0AC0 is a central component in that transition.

Whether you are replacing a failed unit, upgrading an aging drive cabinet, or executing a planned modernization of a multi-axis CNC or robotics cell, this module delivers the power density, communication flexibility, and system integration depth required for a smooth cutover with minimal production downtime.

Seamless Upgrade Solutions

A successful migration to the SINAMICS S120 platform rarely involves a single module swap. In practice, the 6SL3120-1TE26-0AC0 Single Motor Module operates as part of a coordinated drive system. The CU320-2 DP or CU320-2 PN Control Unit serves as the central intelligence, managing axis coordination, safety functions, and fieldbus communication across all connected motor modules on the shared DC bus.

For multi-axis machine tool or robotics retrofits, the 6SL3120-1TE28-5AC0 (85 A Single Motor Module) and 6SL3120-2TE21-8AC0 (Double Motor Module 18 A) are frequently deployed alongside the 6SL3120-1TE26-0AC0 to cover different axis power requirements within the same Booksize cabinet section. The 6SL3100-1BE31-3AA0 Smart Line Module provides the regulated DC bus supply for the entire drive group, replacing the uncontrolled infeed of older SIMODRIVE 611 systems and enabling energy recovery during braking.

Legacy encoder systems — particularly resolvers and HTL incremental encoders common on older Siemens 1FT6 and 1FK6 servo motors — require a Sensor Module Cabinet-Mounted (SMC10 or SMC20) to interface with the DRIVE-CLiQ topology of the S120 platform. This is a critical retrofit component that is often overlooked during initial planning. Similarly, the 6SL3055-0AA00-3AA0 DRIVE-CLiQ Hub Module (DMC20) simplifies wiring in distributed cabinet layouts where motor modules and encoders are physically separated.

On the power supply side, existing 24 VDC cabinet power supplies are generally compatible, but the 6EP1336-3BA00 SITOP PSU300S 20 A stabilized power supply is a recommended pairing for S120 Booksize installations requiring clean, regulated 24 V for the Control Unit and I/O infrastructure. Terminal modules such as the 6SL3162-2AA00-0AA0 provide organized signal and shield termination within the cabinet, reducing EMC issues during commissioning.

For plants integrating the S120 drive system into a broader SIMATIC S7-300 or S7-1500 PLC architecture, the PROFINET or PROFIBUS interface of the CU320-2 allows direct cyclic communication without additional gateway hardware — a significant advantage over older analog speed reference wiring. HMI integration via SIMATIC TP700 or TP1200 Comfort Panels through TIA Portal further streamlines the modernization of the operator interface alongside the drive upgrade.

Retrofit Guidance FAQ

Q: Can I reuse existing motor power cables from my SIMODRIVE 611 installation?
A: In most cases, yes. The 6SL3120-1TE26-0AC0 uses standard IEC motor output terminals. Provided the cable cross-section is rated for 60 A and the insulation is in good condition, existing motor cables to 1FT6 or 1FK7 series motors can typically be reused. Always verify cable screening and grounding continuity before energizing.

Q: What happens to my existing PROFIBUS DP network during migration?
A: The CU320-2 DP Control Unit supports PROFIBUS DP natively, allowing the S120 drive group to integrate directly into an existing SIMATIC S7 PROFIBUS network without replacing the PLC or network infrastructure. If migrating to PROFINET, the CU320-2 PN variant is required.

Q: Do I need to rewrite my PLC program for the new drive?
A: Drive-level function blocks and telegram structures differ between SIMODRIVE 611 and SINAMICS S120. Standard telegrams (e.g., Telegram 1, 5, or 105 for speed/torque control) are supported in both STARTER and TIA Portal Startdrive. PLC programs using standard SINAMICS drive function blocks (SFB/FB) will require adaptation, but the control logic structure is largely preserved.

Q: How much cabinet space does the 6SL3120-1TE26-0AC0 require?
A: The Booksize format has a standard width of 100 mm. When planning a retrofit, account for the Control Unit, Line Module, Motor Modules, and associated terminal and hub modules. In many cases, the S120 Booksize system achieves a smaller overall footprint than the legacy SIMODRIVE 611 installation it replaces.

Q: Can this module be used as a direct spare for an existing S120 installation?
A: Yes. The 6SL3120-1TE26-0AC0 is a standard catalog module. It can be swapped into an existing S120 Booksize drive group as a direct replacement. The Control Unit will automatically detect the new module via DRIVE-CLiQ and load the saved drive configuration, minimizing commissioning time.

Q: What commissioning tools are required?
A: STARTER (standalone) or TIA Portal with the Startdrive add-in are the standard commissioning environments. A standard PC with USB or PROFIBUS/PROFINET connection to the CU320-2 is sufficient. No proprietary hardware dongle is required for basic commissioning.
