A20B-2100-0800 FANUC Spindle Drive PCB Control Circuit Board

 

 

A20B-2100-0800 Description​

The FANUC A20B-2100-0800 is a genuine ​​Memory Module​​ (RAM Board) designed specifically for legacy FANUC CNC (Computer Numerical Control) systems. This critical component acts as the main system's working memory (DRAM), temporarily storing the part programs, system parameters, and operational data required for real-time machine tool control. It is an essential upgrade or replacement part for enhancing the capabilities and maintaining the reliability of older FANUC controllers, ensuring they can handle larger, more complex machining programs without interruption. Proper installation of this module is crucial for the seamless operation of machining centers, lathes, and other industrial equipment powered by compatible FANUC series.

A20B-2100-0800 Features​

  • ​Genuine FANUC Quality:​​ Manufactured to meet FANUC's stringent industrial-grade standards, ensuring maximum reliability, compatibility, and longevity in harsh manufacturing environments.
  • ​Performance Enhancement:​​ Expands the volatile memory (RAM) capacity of the CNC controller, enabling the processing of larger part programs and more complex machining operations.
  • ​Plug-and-Play Compatibility:​​ Designed as an original component for seamless integration with specific FANUC main CPU boards (e.g., A20B-2000-​​​​ series), eliminating compatibility issues.
  • ​High-Speed Data Access:​​ Provides the necessary fast read/write cycles for the CNC's real-time processing demands, supporting smooth servo control and high-speed machining.
  • ​Volatile Memory Design:​​ Like standard RAM, it requires constant power. A backup battery on the CPU board is essential to preserve data when the main power is shut off.

A20B-2100-0800 Material & Application​

  • ​Material & Construction:​
    • ​PCB Substrate:​​ High-grade fiberglass (FR-4) for mechanical strength and electrical insulation.
    • ​Memory Chips:​​ Industrial-grade Dynamic Random-Access Memory (DRAM) integrated circuits.
    • ​Connectors:​​ Gold-plated edge contacts or pins to ensure a reliable, corrosion-resistant connection with the motherboard.
  • ​Primary Application:​
    This module is used as an ​​memory expansion board​​ for legacy FANUC CNC and PMC (Programmable Machine Controller) systems. Its key applications include:
    • Upgrading the main memory capacity of older FANUC controllers (e.g., Series 0, 10, 11, 12, 15).
    • Replacing faulty or damaged memory modules to restore a CNC system to full functionality.
    • Enabling the execution of extensive machining programs that exceed the standard memory of the base CPU board.
