Siemens 6SN1123-1AA00-0KA1 | High-Output SIMODRIVE 611 Power Module
The Siemens 6SN1123-1AA00-0KA1 is a high-capacity, single-axis power module within the renowned SIMODRIVE 611 digital drive family. This heavy-duty module acts as the muscle for CNC machine tools, converting DC link energy into high-torque AC power for spindles and feed motors. Engineered for high-demand applications, it delivers a massive current rating that supports main spindles up to 200A and large feed axes up to 140A. Although Siemens has entered the product cancellation phase for this series, it remains a critical asset for maintaining legacy production lines. Moreover, the robust German construction ensures that the module handles the intense electrical stress found in large-scale metalworking and aerospace manufacturing.
Reliability in a 24/7 production environment requires hardware that can manage significant thermal loads without compromising signal precision. This module features a substantial 21 kg frame designed to dissipate heat efficiently while maintaining the rigorous accuracy required for CNC machining. It integrates seamlessly into the modular SIMODRIVE rack, allowing for direct communication with SINUMERIK controllers via the system bus. In addition, the internal diagnostics provide real-time monitoring of drive health to prevent unexpected downtime during critical milling or turning operations. Therefore, the 6SN1123-1AA00-0KA1 is an indispensable component for facilities looking to sustain the high performance of their existing Siemens-driven machinery.

Frequently Asked Questions (FAQ)
Does this power module include the control card?
No, this is the power stage only; you must install a compatible digital or universal control board into the front slot.
Why is this module significantly heavier than other axis modules?
The 21 kg weight reflects the heavy-duty heat sinks and internal busbars required to safely manage 400A of peak electrical current.
Can I replace a lower-rated 50A module with this 400A unit?
While physically possible within the rack, you must verify that your infeed module and motor parameters are compatible with this power rating.
What cooling precautions should I take for this high-current module?
Siemens recommends ensuring clear airflow and potentially using an add-on cooling fan or hose if operating at high continuous currents.
