Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the 6SN1123-1AB00-0AA1. Always verify electrical and mechanical compatibility before substitution:
- 6SN1123-1AB00-0BA1 — Upgraded revision of the same power module; direct drop-in replacement in most applications
- 6SN1123-1AA00-0AA1 — Lower current rating variant; suitable for lighter-load axes
- 6SN1123-1AB00-0CA1 — Later revision with enhanced thermal management
- 6SN1124-1AB00-0AA1 — Two-axis power module; applicable when consolidating dual-axis drives
- SINAMICS S120 (6SL3xxx series) — Next-generation platform; requires engineering adaptation but offers superior performance and support lifecycle
Note: Konmask.com recommends consulting the SIMODRIVE 611 system manual (Siemens doc no. 6SN1197-0AA00-0BP7) before substitution.
Why Choose the Original Model
- Proven reliability in high-cycle CNC environments with millions of installed units globally
- Seamless integration with existing SIMODRIVE 611 control modules, infeed modules, and SINUMERIK CNC controllers
- Minimized re-commissioning risk — no parameter migration or hardware adaptation required
- Spare parts availability — Konmask maintains stock of both new and refurbished units for rapid dispatch
- Cost-effective maintenance compared to full drive system upgrades
Typical Applications
- CNC machining centers (milling, turning, grinding)
- Industrial robots and gantry systems
- Injection molding machines
- Printing and packaging machinery
- Semiconductor and electronics manufacturing equipment
- Precision servo press and forming lines
System Compatibility
- CNC Controllers: SINUMERIK 840D, 840Di, 810D, 802D
- Infeed Modules: 6SN1145-series (unregulated) / 6SN1146-series (regulated)
- Control Modules: 6SN1118-series (standard / speed/torque setpoint)
- Bus System: SIMODRIVE 611 internal drive bus (not PROFIBUS/PROFINET)
- Motor Compatibility: 1FT6, 1FK6, 1FK7, 1PH7 series Siemens servo/spindle motors
Selection Guide
Use the following criteria to select the correct SIMODRIVE 611 power module for your application:
- Step 1 — Determine axis count: Single-axis (6SN1123-series) vs. two-axis (6SN1124-series)
- Step 2 — Identify current requirement: Match continuous and peak current to motor nameplate data (add 20% safety margin)
- Step 3 — Confirm control module type: Speed/torque setpoint or position control; must match 6SN1118-series variant
- Step 4 — Check revision compatibility: -0AA1, -0BA1, -0CA1 revisions are generally interchangeable; confirm with Siemens compatibility matrix
- Step 5 — Evaluate upgrade path: If the machine is due for modernization, consider SINAMICS S120 migration for extended support lifecycle

Replacement & Compatibility FAQ
Q: Can I replace 6SN1123-1AB00-0AA1 with 6SN1123-1AB00-0BA1?
A: Yes. The -0BA1 is a direct revision upgrade and is mechanically and electrically compatible in virtually all standard installations.
Q: Is the 6SN1123-1AB00-0AA1 still in production?
A: This model has been discontinued by Siemens. Konmask.com supplies new-old-stock (NOS) and refurbished units. For new projects, SINAMICS S120 is the recommended successor platform.
Q: Can this module work with SINUMERIK 828D?
A: No. SINUMERIK 828D uses SINAMICS S120 Combi drives, not SIMODRIVE 611. These are incompatible platforms.
Q: What is the difference between 6SN1123 and 6SN1124?
A: 6SN1123 is a single-axis power module; 6SN1124 is a two-axis power module. They share the same DC bus but serve different axis configurations.
Q: Do you provide a warranty?
A: Yes — 12 months for new units, 90 days for refurbished. All units are tested before shipment.
