Siemens 6SN1123-1AA00-0JA1 SIMODRIVE 611 300 A Power Module
A JA1 power stage with internal cooling with add-on fan or hose cooling required and documented feed motor: 100 a; main-spindle motor: 120 a.
Product Overview
6SN1123-1AA00-0JA1 is a Siemens SIMODRIVE 611 300 A one-axis power module identified by revision JA1. It uses internal cooling with add-on fan or hose cooling required.
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.
Performance
- 300 A one-axis power-module configuration.
- Rated motor currents: Feed motor: 100 A; main-spindle motor: 120 A.
- Cooling arrangement: Internal cooling with add-on fan or hose cooling required.
- Revision JA1 for controlled maintenance identification.
- Designed for feed or main-spindle duty only within a compatible SIMODRIVE 611 system.
