Model-Specific Overview

FANUC A20B-2901-0766 belongs to the A20B-2901 product group and is classified here as a CNC Memory Module. The final suffix and visible revision markings should be retained when requesting a quotation.

Manufacturer-Source Check

Search results confirm that A20B-2901-0766 is traded as a CNC Memory Module. The description remains conservative because a detailed official entry for the complete code was not available in the manuals reviewed.

Identification Checklist

Confirm memory type, stated capacity, module revision, host-board position and any battery-backed data requirements. Before removing the original module, follow the appropriate procedure to back up the FANUC CNC parameters and preserve programs, SRAM data and other user files using a suitable FANUC all-data backup method.

Send REACO CNC clear photos of the complete label, revision marks and connectors together with the machine or control model. Visible identifiers can be compared before stock, condition, price and lead time are confirmed.
