6SL3120-1TE24-5AA3 SIEMENS Sinamics Single Motor Module 45A

Buy online your 6SL3120-1TE24-5AA3 SIEMENS Sinamics Single Motor Module 45A reference 6SL3120-1TE24-5AA3 from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

This SIEMENS SINAMICS S120 power module is a Single Motor Module 45A designed to run one motor axis from the S120 common DC bus. Used across machining centers, lathes and grinders, it serves as a reliable CNC replacement component for high-torque servo or spindle applications where stable current delivery and consistent drive control are required.

Within the S120 platform it provides the inverter stage for a single axis, taking energy from the DC 600V link and supplying a controlled 3AC 400V output up to 45 A. The unit links to a CU320 or SINUMERIK controller via DRIVE-CLiQ for parameterization, diagnostics and axis control. In practice this means quick commissioning in plants already standardized on SINAMICS, straightforward field replacement, and clear status feedback for maintenance teams.

The module supports typical S120 booksize wiring with end-mounted connectors X1, X200, X201, X202, X203, X21 and a front DC link interface for common bus connection to the line module. Rated at 24 kW with a 4 kHz switching frequency, it offers a good balance between dynamic response and thermal performance for demanding duty cycles on production floors where consistent uptime is critical.

Integration is straightforward in existing SINUMERIK-controlled machines. The DRIVE-CLiQ backbone simplifies axis replacement, while the common DC bus concept allows energy sharing with other axes, which is standard practice in S120 cabinets. Built in Germany, this unit is widely used as a spare part or replacement unit for failed modules in legacy and current S120 installations.

Reference: 6SL3120-1TE24-5AA3

Manufacturer: SIEMENS

Product type: SIEMENS SINAMICS 6SL S120 Modules

Main function: Inverter module for one motor axis within a SINAMICS S120 common DC link

Applications: Spindle or high-power servo axes on machining centers, CNC lathes, grinders and production machines using SINUMERIK control

Key technical data: Input DC 600 V via common bus, output 3AC 400 V up to 45 A, rated power 24 kW, switching frequency 4 kHz, DRIVE-CLiQ communication to CU320 or SINUMERIK system, end-mounted connectors X1/X200/X201/X202/X203/X21, front-mounted DC link terminals, Single Motor Module type within SINAMICS S120.

On the shop floor this module is commonly installed as a drop-in replacement when an existing S120 axis inverter trips, loses phase or reports overcurrent faults. Maintenance teams can keep one in industrial spare inventory to shorten repair turnaround and restore machine operation quickly. For retrofit work it is a solid choice when consolidating to S120 hardware while keeping a SINUMERIK control stack already in service.

Technicians typically swap the failed unit, connect the DC link and motor leads, then re-establish DRIVE-CLiQ communications to the CU320 or SINUMERIK. Keeping a tested unit on the shelf minimizes downtime and helps extend machine lifetime through preventive replacement strategies on high-hour axes.

Each unit can be tested on CNC simulators with matched servo motors by skilled engineers for basic functionality, communication and load behavior. Packaging is ESD-safe with protective foam for industrial shipping. Warranty and repair service or exchange service options may be available. Fast dispatch is possible depending on availability, with listing showing shipment within 3 days when in stock.

For unplanned stoppages this module serves as an effective emergency spare to reduce unexpected downtime. Cnc-shopping can also assist with sourcing obsolete parts, provide refurbished units or arrange repair service so older SINUMERIK and SINAMICS installations remain operational. Worldwide shipping available on request.

Frequently asked questions about 6SL3120-1TE24-5AA3:

Does it run on a common DC bus with an S120 line module?
Yes, this Single Motor Module operates from the S120 common DC link at approximately 600 V DC and is used with the appropriate line module in the same rack or cabinet.

Which control units are compatible?
It connects over DRIVE-CLiQ to a CU320 or to a SINUMERIK-based control system using the S120 platform. Check your controller version and firmware for final confirmation.

Is it suitable for spindle duty?
The 45 A, 24 kW rating and 3AC 400 V output make it suitable for many spindle applications as well as high-power servo axes when sized correctly to the motor and load.

What connections are provided on the module?
Field wiring uses the end-mounted connectors X1, X200, X201, X202, X203, X21 and the front DC link terminals. Refer to your cabinet layout and wiring diagrams to match existing connections.

Can this be used as a drop-in replacement for the same reference?
Yes, replacing like-for-like with the same reference is standard practice. Parameters reside in the control unit over DRIVE-CLiQ, which simplifies axis recognition after installation.
