Siemens 6SN1123-1AA00-0DA2 SIMODRIVE 611 80 A Power Module
A DA2 power stage with internal cooling and documented feed motor: 28 a; main-spindle motor: 30 a.
Key Information
6SN1123-1AA00-0DA2 is a Siemens SIMODRIVE 611 80 A one-axis power module identified by revision DA2. It uses internal cooling.
The module supplies the power stage for a compatible feed or spindle axis. Selection requires the installed control module, infeed, motor, DC link, connectors and cooling arrangement to match the exact article.
Functions
- Provides a one-axis 80 A SIMODRIVE 611 power stage.
- Supports the documented motor duties: Feed motor: 28 A; main-spindle motor: 30 A.
- Uses internal cooling.
- Maintains revision traceability through the complete 6SN1123-1AA00-0DA2 article number.
- Integrates with compatible 611 infeed, control and feedback hardware.
