The FANUC A16B-1010-0285 is a discontinued Series 0 Model B digital master PCB. It is commonly identified as a three-axis master board with SV LSI and is used in three- or four-axis CNC configurations depending on the installed software, servo hardware and option boards.

Documented applications include FANUC 0-MB, 0-TTB, 0-PB, 0-GB and 0P4C systems. Because the board stores and coordinates machine-specific data and options, replacement requires more than matching the base drawing number.

Series 0B Master-Control Functions

A16B-1010-0285 provides the main CNC processing, digital servo coordination, program and parameter memory, system-option management and machine communication functions. Spindle, graphics, I/O and expanded-axis capabilities depend on the complete control configuration and fitted peripheral boards.

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

A16B-1010-0285 is the three-axis SV LSI master board used in 3/4-axis systems. A16B-1010-0286 is the related two-axis master board commonly used in 0-TB lathe controls. They are not direct substitutes without confirming the complete CNC configuration.

Replacement and Backup Requirements

Match the full part number, printed revision suffix, CNC type, software ROM set, SRAM capacity, PMC ladder, servo software, connectors and fitted daughterboards. Back up parameters, programs, offsets, diagnostics and PMC data before removal. Photograph all option positions and transfer components only after compatibility is verified.
