The FANUC A16B-1010-0286 is a discontinued Series 0 Model B digital master PCB designed primarily for compatible 0-TB CNC lathe configurations. Commonly identified as a two-axis master board with SV LSI, it coordinates CNC processing, two digital servo axes, spindle control, memory and system communication.

This legacy board is configuration-sensitive. Confirm the complete PCB number, printed revision suffix, control type, software ROMs, memory, PMC arrangement and installed option boards before ordering.

Series 0-TB Control Functions

A16B-1010-0286 acts as the central processor and digital servo-control board in its supported configuration. It also manages CNC programs, parameters and system options. Graphics, machine I/O and expanded axis functions can depend on separate peripheral or plug-in boards fitted by the machine builder.

A16B-1010-0286 vs. A16B-1010-0285

A16B-1010-0286 is the two-axis version, while A16B-1010-0285 is commonly identified as the three-axis master PCB with SV LSI. They should not be treated as direct substitutes solely because both belong to the FANUC Series 0B family.

Replacement and Data Checks

Match the board revision, software ROM set, SRAM capacity, PMC ladder configuration, servo software, connectors and every fitted daughterboard. Back up parameters, programs, offsets, diagnostics and PMC data before removal. Photograph option locations and transfer components only when their compatibility is confirmed.
