Siemens 6SN1145-1BA01-0BA2 SIMODRIVE 611 16/21 kW Infeed/regenerative feedback module
A 16/21 kW infeed/regenerative feedback module with internal cooling for a compatible modular drive group.
Key Information
6SN1145-1BA01-0BA2 is a Siemens SIMODRIVE 611 infeed/regenerative feedback module rated at 16/21 kW. The unit combines closed-loop regulated operation with internal cooling.
This article forms the mains-side energy interface for a compatible 611 drive group. Its exact suffix keeps the power class, contact arrangement and hardware revision distinct from visually similar line modules.
Functions
- Feeds the SIMODRIVE 611 DC link from the plant mains supply.
- Returns regenerative motor energy to the mains within the documented system configuration.
- Provides the 16/21 kW module class with closed-loop regulated behavior.
- Uses internal cooling and the specified mains-contact interface.
- Supports coordinated operation with compatible 611 power modules and controls.
