FANUC-Documented CPU Card

FANUC maintenance manuals identify A20B-3300-0050 as a CPU card whose function is CNC control. It is documented for Series 16i and 18i Model A hardware, and the earlier B-63005EN/01 manual specifies a Pentium processor. The part is therefore classified as a CPU control card/PCB rather than a servo card or complete CNC control unit.

CPU Card and Memory Configuration

FANUC hardware lists DRAM, SRAM and FROM as separately specified modules. A20B-3300-0050 identifies the CPU card itself; it does not confirm the capacity of every memory module installed on the assembly. Compare the fitted memory modules and hardware configuration before replacement.

Preparation Before Replacement

Back up CNC parameters, programs, offsets, PMC data and option-related files before removing a CPU or memory card. Replacement should be performed with power isolated and electrostatic-discharge precautions in place. After installation, restore and verify the machine data according to the machine builder and FANUC procedures.

Exact-Match Checklist

  • Match A20B-3300-0050 and the full PCB revision.
  • Confirm the original control is a compatible Series 16i/18i Model A configuration.
  • Compare the motherboard, connectors and CPU-card mounting position.
  • Record the fitted DRAM, SRAM and FROM module numbers separately.
