SIEMENS 6SN1123-1AA00-0DA0 Simodrive LT-Modul 80A

Buy online your SIEMENS 6SN1123-1AA00-0DA0 Simodrive LT-Modul 80A reference 6SN1123-1AA00-0DA0 from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

This SIEMENS module from the SIMODRIVE 611 family provides the axis power stage for one axis at 80 A. It is a proven choice for feed axes and selected spindle applications in machine tools using 1FT5, 1FT6, 1PH, and asynchronous motors within the specified current ranges. Suitable as a drop-in replacement for faulty units, it supports fast return to service on CNC lines and maintenance rebuild projects.

The unit serves as the power section in a SIMODRIVE 611 rack, supplying controlled motor current to a single axis while interfacing with the corresponding control board and infeed. With internal heat dissipation, it is intended for cabinet mounting where airflow is managed by the machine enclosure. This design is common across many 611 installations on the production floor.

Rated motor current alignment is a key selection point. This 80 A version is typically applied with motor families at the following nominal ratings: 1FT5 up to 40 A, 1FT6 up to 28 A, 1PH up to 30 A, and asynchronous motors up to 30 A. Matching the module current class to the motor and mechanical load helps avoid nuisance trips and keeps thermal margins in check during continuous duty.

Integration follows the standard SIMODRIVE 611 mechanical layout with the familiar power busbars and signal connectors. Maintenance teams can replace a failed power section on the rack without modifying cabinet cutouts or wiring topology, which keeps repair turnaround short and limits machine downtime.

Reference: 6SN1123-1AA00-0DA0

Manufacturer: SIEMENS

Product type: SIEMENS SIMODRIVE 6SN1123 LT-Modul 80A

Main function: One-axis power section for SIMODRIVE 611 racks, 80 A class, internal heat dissipation

Applications: CNC machine-tool feed axes and selected spindle duties using SIEMENS 1FT5, 1FT6, 1PH, and asynchronous motors within stated current ranges

Key technical data: SIMODRIVE 611 series module, one-axis configuration, 80 A rating, internal cooling design, motor current compatibility typically up to 40 A for 1FT5, 28 A for 1FT6, 30 A for 1PH and asynchronous motors, suitable as a tested replacement unit for faulty modules

On the shop floor this unit is commonly sourced as a spare part for legacy 611 racks in machining centers, turning cells, and grinding machines. It is used as a field replacement when overcurrent faults, intermittent trips, or thermal alarms trace back to a failing power section. Many maintenance teams keep an industrial spare inventory of this class to shorten recovery time.

For planned outages and retrofit work, it serves as a reliable CNC replacement component when standardizing current classes across multiple machines. Keeping a matched 80 A module as a stocked replacement unit supports preventive maintenance and extends service life of SIMODRIVE 611 installations.

Each unit is a tested unit verified on dedicated SIMODRIVE 611 CNC simulators with SIEMENS 1FT servo motors by skilled engineers. Packaged in ESD-safe materials with protected connectors for industrial shipping. Warranty is included. Many stocked items ship directly from our Florida facility, depending on availability.

Cnc-shopping USA supports obsolete part sourcing for SIMODRIVE 611, along with repair service and exchange service when suitable. This helps keep older CNC equipment running, reduces unexpected downtime, and preserves uptime while planning long-term upgrades. Worldwide shipping available.

Frequently asked questions about 6SN1123-1AA00-0DA0:

How do I confirm that this Siemens Simodrive LT-Modul 80 A version matches my axis?
Check your existing module code and verify the motor family and nominal current. This 80A class aligns with 1FT5 up to 40 A, 1FT6 up to 28 A, and 1PH or asynchronous motors up to 30 A, which suits many medium-duty axes.

Is it compatible with standard SIMODRIVE 611 racks and infeed units?
Yes, it is designed for the SIMODRIVE 611 platform and mounts in the standard rack layout with the usual busbars and signal connectors. Pair it with the appropriate control board and infeed specified by your machine documentation.

What cooling approach does this Siemens Simodrive 611 model use?
This version uses internal heat dissipation intended for enclosure mounting (and a small 2wires fan, which is always replaced by CNC-Shopping USA as preventive maintenance). Ensure the cabinet ventilation matches the OEM specification to maintain stable thermal conditions.

Do you provide refurbished units or repair for this Siemens axis model?
Cnc-shopping USA can supply refurbished unit options depending on inventory and can coordinate repair service. Contact our Sales or Tech team with the exact code and fault / alarm details for guidance.
