Siemens 6FC5313-0AB00-0AA1 | SINUMERIK 840D NCU 573.x Control Unit

Product Overview
The Siemens 6FC5313-0AB00-0AA1 is an NCU (Numerical Control Unit) module for the SINUMERIK 840D powerline CNC system. This variant features the -0AA1 suffix, indicating a hardware revision of the NCU 573.x base model.

6FC5313-0AB00-0AA0 vs 6FC5313-0AB00-0AA1
The key difference between these two models is the hardware revision level. Both modules are functionally identical for SINUMERIK 840D powerline systems, with the AA1 variant serving as a direct replacement for AA0 units.
