Siemens 6SN1123-1AA00-0KA1 SIMODRIVE 611 400 A Power Module
A KA1 power stage with internal cooling with add-on fan or hose cooling required and documented feed motor: 140 a; main-spindle motor: 200 a.
Product Overview
6SN1123-1AA00-0KA1 is a Siemens SIMODRIVE 611 400 A one-axis power module identified by revision KA1. 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
- 400 A one-axis power-module configuration.
- Rated motor currents: Feed motor: 140 A; main-spindle motor: 200 A.
- Cooling arrangement: Internal cooling with add-on fan or hose cooling required.
- Revision KA1 for controlled maintenance identification.
- Designed for feed or main-spindle duty only within a compatible SIMODRIVE 611 system.

FAQ
Why does 6SN1123-1AA00-0KA1 require additional cooling?
6SN1123-1AA00-0KA1 is a 400 A power module whose documented installation requires an add-on fan or hose cooling.
What feed-motor rating applies to 6SN1123-1AA00-0KA1?
6SN1123-1AA00-0KA1 has a documented feed-motor rated current of 140 A.
What spindle-motor rating applies to 6SN1123-1AA00-0KA1?
6SN1123-1AA00-0KA1 has a documented main-spindle rated current of 200 A.
Can 6SN1123-1AA00-0KA1 run safely without its auxiliary cooling arrangement?
No. The add-on fan or hose-cooling requirement is part of the 6SN1123-1AA00-0KA1 configuration and must be preserved.
Which system checks precede a 6SN1123-1AA00-0KA1 exchange?
Confirm the 400 A module class, axis control card, infeed, busbars, motor, cabinet clearances and cooling system before exchanging 6SN1123-1AA00-0KA1.
