Siemens 6SL3120-1TE26-0AA3 S120 Single Motor Module 60A

Product Overview

Siemens 6SL3120-1TE26-0AA3 S120 Single Motor Module 60A: Seamless Replacement & Upgrade Solution

The Siemens 6SL3120-1TE26-0AA3 is a SINAMICS S120 Booksize Single Motor Module rated at 60A output current, designed for high-performance servo and vector drive applications in industrial automation. Whether you are replacing a failed unit, upgrading from an older SINAMICS S120 generation, or migrating from a legacy MASTERDRIVES MC or SIMODRIVE 611 platform, this module delivers a smooth, validated transition with minimal engineering rework.

The 6SL3120-1TE26-0AA3 slots directly into the standard S120 Booksize power section rack alongside a compatible 6SL3100-1BE31-0AA0 Line Module or 6SL3130-7TE21-6AA3 Smart Line Module, sharing the DC bus and DRIVE-CLiQ communication backbone without requiring additional interface converters. The module communicates natively over DRIVE-CLiQ and is fully compatible with PROFIBUS DP and PROFINET IO higher-level fieldbus architectures when paired with a 6SL3040-1MA01-0AA0 CU320-2 Control Unit or equivalent S120 CU. This means your existing PLC program — whether running on a SIMATIC S7-300, S7-400, or S7-1500 — requires no fieldbus reconfiguration after the swap.

For facilities migrating from SIMODRIVE 611 universal or MASTERDRIVES MC booksize drives, the 6SL3120-1TE26-0AA3 provides a well-documented upgrade path. Motor encoder feedback wiring can be adapted using a 6FX2002-2EQ10 DRIVE-CLiQ encoder cable or a 6SL3055-0AA00-5BA3 SMC20 Sensor Module Cabinet-Mounted, eliminating the need to re-terminate motor cables at the motor terminal box. The Booksize form factor ensures the replacement fits within the existing control cabinet footprint, preserving DIN rail spacing and bus bar alignment without mechanical modification.

Power supply compatibility is maintained through the shared 600V DC bus architecture of the S120 Booksize family. The 6SL3120-1TE26-0AA3 draws from the same infeed as adjacent modules — including 6SL3120-1TE21-0AA3 Single Motor Modules at lower current ratings or 6SL3120-2TE26-0AA3 Double Motor Modules — making it straightforward to expand or reconfigure multi-axis systems without replacing the infeed section. The 24V DC auxiliary supply for the control electronics is sourced from the standard S120 system power supply, typically a 6EP1333-3BA00 SITOP PSU100S or equivalent, which remains unchanged during the module swap.

Commissioning after replacement is performed using STARTER or SINAMICS Startdrive within TIA Portal. The DRIVE-CLiQ topology is automatically recognized upon first power-up, and the motor data set can be transferred from the existing project file or re-entered from the motor nameplate. For sites running Safety Integrated functions — such as Safe Torque Off (STO) or Safe Stop 1 (SS1) — the safety parameters stored in the CU are retained and do not require re-certification after a like-for-like module replacement, significantly reducing downtime and re-validation effort.

Spare parts management is a critical consideration for any S120-based machine. Keeping a tested 6SL3120-1TE26-0AA3 in stock alongside complementary components such as a 6SL3162-2BM00-0AA0 DC bus busbar, 6SL3162-2MA00-0AA0 shield connection kit, and a set of 6SL3060-4AX00-0AA0 DRIVE-CLiQ cables ensures that unplanned downtime can be resolved within hours rather than days. Our inventory is pre-tested, serialized, and ships with full documentation including the factory test report and firmware version record.

Seamless Upgrade Solutions

A successful S120 migration or spare-parts replacement typically involves more than the motor module itself. During the upgrade process, engineers commonly source the following components as part of the same project:

The 6SL3040-1MA01-0AA0 CU320-2 DP Control Unit serves as the central intelligence of the S120 drive system, managing all axis coordination and fieldbus communication. When upgrading from a SIMODRIVE 611 system, the CU320-2 replaces the legacy NCU or master drive controller and is the first component to configure before commissioning the 6SL3120-1TE26-0AA3 motor module. Paired with a 6SL3100-1BE31-0AA0 Active Line Module, the infeed section provides clean, regulated DC bus power with active front-end regeneration, improving energy efficiency compared to older uncontrolled rectifier infeeds.

Encoder signal conversion is handled by the 6SL3055-0AA00-5BA3 SMC20 Sensor Module, which bridges legacy sin/cos or TTL encoder outputs to the DRIVE-CLiQ protocol required by the 6SL3120-1TE26-0AA3. This eliminates the need to replace motors or re-terminate encoder cables during the migration. For multi-axis cabinets, the 6SL3162-2BM00-0AA0 DC bus busbar set and 6SL3162-2MA00-0AA0 shield connection kit ensure proper mechanical and electrical integration of the new module into the existing rack. Communication between modules is maintained via 6SL3060-4AX00-0AA0 DRIVE-CLiQ cables, which are available in standard lengths and should be replaced as a precaution during any major drive overhaul.

For applications requiring operator interface at the machine level, a 6AV2124-0GC01-0AX0 SIMATIC HMI TP700 Comfort panel integrates directly with the S120 system via PROFINET, providing real-time drive diagnostics and parameter access without additional gateway hardware. Power supply integrity for the control section is maintained by a 6EP1333-3BA00 SITOP PSU100S 24V/5A unit, which provides stable auxiliary voltage to the CU and I/O modules throughout the upgrade process.

Retrofit Guidance FAQ

Q: Can I reuse my existing motor wiring when replacing with the 6SL3120-1TE26-0AA3?
A: Yes. The motor power terminals on the S120 Booksize module use standard screw terminals compatible with existing cable cross-sections up to 16mm². No re-termination at the motor end is required. Verify cable insulation rating is suitable for the inverter output (dU/dt).

Q: Will my PROFIBUS PLC program need modification after the swap?
A: No, provided the GSD file and drive telegram (e.g., Telegram 1 or 111) remain unchanged in the CU320-2 configuration. The PLC sees the same process data interface regardless of which physical motor module is installed.

Q: How do I handle the encoder interface when migrating from SIMODRIVE 611?
A: Use the SMC20 Sensor Module Cabinet-Mounted (6SL3055-0AA00-5BA3) to convert the existing sin/cos or TTL encoder signal to DRIVE-CLiQ. Mount the SMC20 in the cabinet and connect it to the 6SL3120-1TE26-0AA3 via a standard DRIVE-CLiQ cable.

Q: Does the module fit in the same cabinet slot as the unit it replaces?
A: The 6SL3120-1TE26-0AA3 is a standard S120 Booksize module. If replacing another S120 Booksize module of the same width class, it is a direct mechanical fit. Migration from SIMODRIVE 611 Booksize may require a new mounting rail section but the overall cabinet depth and height are compatible.

Q: Are Safety Integrated parameters retained after replacement?
A: Safety parameters are stored in the CU, not the motor module. A like-for-like motor module replacement does not require safety re-commissioning or re-certification under IEC 62061 / ISO 13849, provided the CU and safety wiring are unchanged.

Q: What firmware version does this unit ship with?
A: Units ship with the factory-installed firmware. The firmware version is documented in the included test report. Firmware upgrades can be performed via STARTER or Startdrive using a standard CF card or USB connection to the CU.
