The FANUC A02B-0319-B500 is a Series 0i-D CNC basic unit used in compatible FANUC control-system configurations.

FANUC maintenance documentation officially identifies this part as the 0i Basic Unit with no expansion slot. In an LCD-mounted CNC configuration, the control unit is installed behind the compatible LCD display assembly.

When equipped with the appropriate M-series main board, software package, MDI unit, axis-control hardware, and machine configuration, the A02B-0319-B500 may form part of a FANUC 0i-MD CNC system. FANUC classifies 0i-MD as an M-series version of the Series 0i-D platform.

The A02B-0319-B500 is commonly found in organic search results under names such as:

• FANUC 0i-MD CNC Controller
• FANUC Series 0i-D Basic Unit
• FANUC CNC Control Basic Unit
• FANUC A02B-0319-B500 Controller
• FANUC 0i-D Control Unit

Because this is a configurable basic unit rather than a universally complete plug-and-play CNC system, the installed PCBs, software, parameters, programs, display, and MDI configuration must be confirmed before replacement.

System Configuration Note

The A02B-0319-B500 part number alone does not define the complete 0i-MD system configuration.

FANUC documentation lists several separate hardware components for the Series 0i-D platform, including different:

• Main boards
• Axis-control cards
• LCD display units
• Horizontal and vertical MDI units
• T-series and M-series MDI configurations
• Touch-panel and non-touch-panel display assemblies

Before ordering, please confirm:

• Complete FANUC system model
• A02B-0319-B500 identification label
• Installed main-board number
• Axis-card configuration
• M-series software package
• LCD and MDI part numbers
• Number of controlled axes and paths
• Installed CNC options
• Parameter, program, PMC, and SRAM backups
• Whether a basic unit or complete populated control system is required

Software and machine data may need to be restored after replacement according to the original CNC configuration.

Related Basic Unit

FANUC documentation distinguishes these two Series 0i-D basic-unit structures:

• A02B-0319-B500: Basic Unit, No Slot
• A02B-0319-B502: Basic Unit, Two Slots

They should not be treated as identical where expansion-board capacity is required.

Common Use Cases

• FANUC 0i-MD CNC basic-unit replacement
• Series 0i-D controller restoration
• Repair of a CNC that cannot complete startup
• Troubleshooting unstable control-system operation
• Replacement of damaged internal control hardware
• Rebuilding a compatible populated 0i-MD control unit
• Preparation of a tested spare CNC controller
