The FANUC A20B-1007-0920 is an internal connector board used in selected FANUC CNC servo amplifier assemblies. It provides the fitted electrical connection between compatible internal boards and components; it is not a complete servo drive, standalone controller or general-purpose I/O module.

Known markings include A20B-1007-0920/01A and A20B-1007-0920/02A. Some /02 boards also carry the auxiliary marking A350-1007-T922/02. Order by the complete number printed on the original PCB because revision, connector arrangement and host amplifier configuration can affect compatibility.

A20B-1007-0920 Product Information

Internal Connector Board Function

A connector PCB forms part of the amplifier’s internal electrical assembly. Correct installation depends on the matching control board, power board, connector locations and mechanical mounting. This board does not replace the complete amplifier and cannot be commissioned independently.

Revision and Amplifier Compatibility

Before ordering, compare the full A20B-1007-0920 number, suffix revision, A350 auxiliary marking, connector positions, dimensions, mounting points and the complete A06B number of the host amplifier. Do not substitute A20B-1007-0880, -0890, -0900, -0910 or -0930 only because they belong to the same connector-board family.

Testing and Installation Notes

REACO CNC checks the label, PCB condition, connectors, solder joints and applicable electrical functions before shipment. Disconnect incoming power and allow the DC bus to discharge before opening the amplifier. Installation should be completed by qualified CNC personnel using ESD protection.
