The GE Fanuc A20B-2900-0290/05B ROM Sub Module is a key memory component used in GE Fanuc CNC systems. It provides 1MB of non-volatile storage for critical system data, such as the operating system and CNC control programs. This module ensures the CNC machine operates smoothly and reliably, storing the essential data that the control system needs during startup and operation. Despite being an older model, it continues to serve many legacy GE Fanuc systems in various industrial automation applications, such as CNC machines and robotics.
