6SN1145-1BB00-0EA1 is a Siemens SIMODRIVE 611A/D line module with a 80 kW converter rating and hose / internal heat removal. It supplies the common DC-link section of a modular SIMODRIVE 611 drive group.

The line module operates with the specified mains-side reactor and filter arrangement, the connected axis modules and the cabinet cooling concept selected for the machine.

• Provides a 80 kW line-infeed position for the modular SIMODRIVE 611 system.
• Uses hose / internal heat removal and must remain matched to the cabinet thermal design.
• Supplies the shared DC link used by compatible SIMODRIVE axis power modules.
• Works with the mains-side reactor and filter configuration defined for the drive group.
• Keeps the complete 6SN1145-1BB00-0EA1 suffix visible to distinguish closely related line-module variants.

• 6SN1145-1BB00-0EA1 belongs in a compatible SIMODRIVE 611 modular drive lineup.
• The replacement line module must retain the 80 kW converter class and hose / internal heat removal.
• Confirm mains voltage, line reactor, line filter, connected DC-link load and control interfaces.
• Review the total axis-module demand and any regenerative operating requirement.
• Match mechanical width, bus connections, cooling ducting or hose arrangement and connector positions.

• Use the full 6SN1145-1BB00-0EA1 article number rather than selecting only by the 80 kW rating.
• Record the complete drive lineup, DC-link connections, line components and terminal assignments.
• Preserve the hose / internal heat removal construction during spare selection or retrofit planning.
• Observe DC-link isolation and discharge procedures before work on the drive group.
• After replacement, test precharge, DC-link stability, axis operation and protective functions.
