Siemens 6SN1145-1BB00-0EA1 IR Module

Siemens 6SN1145-1BB00-0EA1 is the SIMODRIVE 611 Infeed/Regeneration (IR) module, a dedicated feedback and power‑management card used within the SIMODRIVE 611 drive family to handle energy flow between the motor and the DC bus. Designed for 611‑A and 611‑D configurations, this IR module supports an 80/104 kW rating and provides closed‑loop control with internal cooling to manage dissipation in demanding industrial environments. As an IR module, it coordinates regenerative energy feedback and infeed control to the DC bus, enabling precise motor torque and speed regulation during braking and energy recovery and ensuring stable drive operation. The module is intended for high‑power servo applications and is commonly employed in manufacturing equipment and CNC‑type machines that rely on the SIMODRIVE 611 platform for reliable, energy‑aware performance. The 6SN1145-1BB00-0EA1 is widely listed by Siemens and third‑party distributors as the SIMODRIVE 611 IR Infeed/Regeneration module, 80/104 kW, with internal cooling and closed‑loop control, reflecting its role as a key power module in the 611 system.
