Product Description
The Siemens 6FC5372-0AA00-0AA2 is a legacy numerical control unit (NCU) for the SINUMERIK 840D sl platform, providing centralized control for multi-axis CNC systems. Designed for machine tools, robotics, and precision manufacturing, this control unit integrates motion control, PLC functionality, and industrial communication interfaces in a single compact module.
Powered by an Intel Celeron M 1.2 GHz processor, the NCU offers 3 MB dedicated NC memory, 256 MB DRAM, and 1 MB non-volatile memory, ensuring stable execution of complex motion control programs. The embedded S7-300 PLC (317-2 DP) with 512 KB user memory enables efficient automation logic and integration into broader Siemens systems. Communication is supported via PROFIBUS DP and Industrial Ethernet, allowing seamless connectivity in factory networks.
The 6FC5372-0AA00-0AA2 is ideal for high-performance CNC applications requiring deterministic control, precise machining, and reliable system operation. Note that this unit has been superseded by newer models such as the NCU 720.3B PN and NCU 720.5, but spare parts and maintenance services remain available for legacy systems.
