Siemens 6SN1123-1AA00-0AA1 1-Axis 15 A Power Module

The Siemens 6SN1123-1AA00-0AA1 is a single-axis SIMODRIVE 611 power module with internal cooling. Siemens documentation identifies it as the 15 A power-module generation with rated motor currents of 7.5 A for 1FT5 and 5 A for 1FT6 / induction-motor applications.

Article & System Context

Product Profile

The module provides the power stage for one motor axis in a modular SIMODRIVE 611 system. It is combined with the appropriate plug-in control unit and an infeed module through the common 611 DC-link architecture.

The 0AA1 generation is legacy hardware and was followed by 6SN1123-1AA00-0AA2. System replacement should preserve the control-unit, motor and cooling requirements of the installed axis.

Function in the System

System Role

Single-Axis Power Stage
Supplies one motor axis in the SIMODRIVE 611 modular drive system.
Internal Cooling
Uses the internal-cooling construction for the 15 A power-module class.
Multiple Motor Applications
Siemens documents rated currents for 1FT5, 1FT6 and induction-motor use.
Modular Control Unit Interface
Requires the correct plug-in 611 control unit for the target motor and control function.
System Matching

Compatibility

Use 6SN1123-1AA00-0AA1 with the correct SIMODRIVE 611 infeed module, control unit and motor. When migrating to 6SN1123-1AA00-0AA2, verify motor-current rating, module width, cooling, control-unit compatibility and the installed DC-link / bus arrangement.
