Fanuc – CFG8V02GVBZWS‑ZAVEB – 2 GB FROM/SRAM Memory Module for 31i‑B/32i‑B CNC

Main Features

• Purpose: Non-volatile memory module (FROM + SRAM) used in Fanuc 31i‑B / 32i‑B CNC controls for firmware, operator files, and dynamic data storage  

• Memory Capacity: 2 GB, supports large part programs and system data—maximum supported by many Fanuc controllers  

• Memory Types:

  • FROM: Flash memory used for system firmware and operator programs

  • SRAM: Temporary storage for runtime data and configuration settings  

• Compatibility & Constraints:

  • Works specifically with Fanuc 31i‑B/32i‑B controllers

  • Must contain matching firmware image and hardware ID to avoid “SYS CNTL” errors

  • Formatted in FAT/FAT16; 2 GB is the largest size officially supported—cards over this may cause issues  

• Replacement Note: Cloning or replacing the module requires correct imaging and ID programming—simple flash copy is insufficient
