FANUC A20B-1003-0090 Single-Axis Servo Control PCB

FANUC A20B-1003-0090 Product Overview

The FANUC A20B-1003-0090 is a single-axis AC digital servo control PCB used in compatible FANUC A06B-6058 S-series servo amplifier units. It forms the control section of the amplifier and works with the corresponding power section to manage servo operation.

This A20B number identifies the control PCB rather than a complete servo drive. Correct replacement depends on the complete board number, revision markings and the full A06B-6058-Hxxx number of the original amplifier.

Control PCB and Complete Drive

The A20B-1003-0090 is installed as the control or upper PCB in applicable single-axis amplifiers. The complete drive also contains a power or base PCB, power components, housing and connection hardware. These parts are not included with a board-only order unless stated in the quotation.

Revision and Compatibility Check

Before ordering, compare the complete A20B-1003-0090 number, printed revision, connector arrangement and the complete A06B-6058 amplifier number. The associated base or power PCB should also be identified because power sections and amplifier ratings can vary.

Descriptions such as tapered shaft, keyed shaft, brake, flange mount and encoder apply to servo motors—not to this PCB—and should not be used to determine board compatibility.
