SIMODRIVE 611 6SN1145-1BA01-0BA2 | 16kW Power Supply with Contactor

Siemens 6SN1145-1BA01-0BA2 | SIMODRIVE 611 Infeed/Regenerative Feedback Module

The Siemens 6SN1145-1BA01-0BA2 is a high-performance power supply unit designed for the legendary SIMODRIVE 611 converter system. This 16/21 kW module serves a dual purpose by providing stabilized DC link power to drive modules and managing energy recovery. Unlike standard power supplies, this unit features regenerative feedback capabilities that return excess braking energy directly to the mains supply. Engineers frequently specify this module for CNC machine tools and complex robotic cells where energy efficiency is a priority. Furthermore, the integrated mains contactor with a break contact ensures a high level of operational safety during emergency stop conditions.

Reliability is the hallmark of the SIMODRIVE 611 series, and this module continues that tradition with its robust internal cooling design. Because it handles significant power loads, the internal air-cooling system effectively dissipates heat to maintain peak performance during heavy machining cycles. Moreover, the compact housing allows for efficient use of cabinet space, which is often at a premium in modern industrial facilities. Although the manufacturer discontinued this series in 2015, it remains an essential spare part for maintaining millions of existing automation lines worldwide. Therefore, choosing a high-quality replacement module like the 6SN1145-1BA01-0BA2 is vital for extending the lifecycle of your CNC infrastructure.

Frequently Asked Questions (FAQ)

What is the main benefit of "Regenerative Feedback" in this module?

Regenerative feedback allows the drive to recycle energy created during motor deceleration, which lowers total factory power consumption.

Can I replace a 10 kW module with this 16/21 kW version?

Generally, yes, as long as the physical frame size and control connections match your existing SIMODRIVE 611 rack configuration.

Does this module include the internal cooling fan?

Yes, this specific model features an internal cooling design with pre-installed fans to manage heat dissipation effectively.

What should I check if the integrated mains contactor fails to pull in?

You should verify the enable signals from your PLC and check the auxiliary break contacts for proper continuity and logic.
