The FANUC A05B-2650-C040 is the replacement specification for the two-slot backplane used in compatible FANUC R-30iB Mate robot controllers. It provides the mounting and electrical interconnection point for compatible controller PCBs.

FANUC documentation lists A05B-2650-H080 as the ordering specification, A05B-2650-C040 as the replacement-part specification and A20B-8200-0680 as the backplane PCB. This is more precise than listings that describe it as an entire robot controller cabinet.

Backplane Function

The A05B-2650-C040 forms part of the internal control-electronics structure of the R-30iB Mate cabinet. Its two-slot backplane supports compatible boards and provides connections for power and internal signal distribution.

The backplane does not control robot motion by itself. Operation depends on the main board, software, memory, servo amplifier, emergency-stop unit, power supply, I/O hardware, teach pendant and other controller components.

Basic Unit and Included-PCB Clarification

Search results call this model an R-30iB Mate basic unit, backplane module, host control system or backplane with PCBs. Confirm the supplied content from photographs and the packing list.

Do not assume a backplane includes the main board, option boards, memory, software, power supply, servo amplifier or controller cabinet. If PCBs are installed, record every board number and revision before ordering or exchange.

R-30iB Mate and Mate Plus Difference

The A05B-2650-C040 is documented for an R-30iB Mate backplane. The similar A05B-2680-C040 is commonly identified as an R-30iB Mate Plus two-slot backplane. Similar appearance and the shared C040 ending do not confirm interchangeability.

Compatibility Note

Before ordering, please verify:

• Complete A05B-2650-C040 number
• R-30iB Mate controller and cabinet version
• Robot model and controller serial number
• Existing A20B-8200-0680 backplane PCB number
• Main-board and option-board numbers and revisions
• Mini-slot and connector arrangement
• Controller software and installed options
• Power-supply and servo-amplifier configuration
• Whether a bare or populated backplane is required
• Current alarms and fault symptoms

Compatibility depends on the original controller configuration. Do not select this unit only because a cabinet is marked R-30iB, R-30iB Mate or R-30iB Mate Plus.

Replacement and Troubleshooting

Replacement may be appropriate for damaged slots, broken connectors, burnt or corroded conductors, unstable board connections or a confirmed internal power or communication fault.

Also inspect the power supply, main board, option boards, connectors and cabinet wiring. If the assembly includes a main board or memory, back up accessible robot programs, system files, mastering data, frames, I/O configuration and application settings before removal.

Common Use Cases

• Replacement of a failed A05B-2650-C040 backplane
• Repair of an R-30iB Mate controller basic unit
• Restoration of stable PCB slot connections
• Rebuilding a compatible FANUC robot controller
• Preparation of a tested controller spare
