FANUC AiSP Spindle Amplifier A06B-6222-H022

What A06B-6222-H022 is

A06B-6222-H022 is listed by the seller's shop as an AiSP spindle amplifier module — the A06B module that drives the spindle. The AiSP designation in its listing is the spindle counterpart to the Ai SV of its sibling: the A06B-6222-H015 is a servo module under the same group number, and the H-suffix alone separates the two roles. No other pair in the catalogue makes the suffix matter more.

It belongs to the spindle amplifiers family, and the A06B table shows the pair together so a buyer reading a cabinet door can confirm which of the two the label in hand actually is.

Where A06B-6222-H022 works

The module drives the spindle motor under the control's command — spindle speed, orientation and tapping cycles all pass through it. Its failure presents as a spindle that will not start, will not orient, or trips under load, on a machine whose feed axes still run. That asymmetric presentation is the spindle module's signature, and it is the first thing the desk establishes on an H022 inquiry.

The motor behind the module is the other suspect in every one of those presentations. Quoting the spindle motor's number alongside the amplifier's lets the answer cover the chain; quoting the amplifier alone invites a follow-up question that costs a day.

Condition options for A06B-6222-H022

The listing fixes the module's identity; its shelf condition varies with stock and is stated on inquiry — new, new-surplus or used, in the seller's usual words. Spindle modules are often bought against a machine that is down and earning nothing, so the condition conversation here is usually about tested evidence and speed rather than about the label word alone.

The used FANUC parts page defines the condition ladder and the seller's warranty that follows it — 3 months on a used module, 1 year on a new one — and the test video option that lets a buyer watch the unit run before it ships.

Testing A06B-6222-H022 before dispatch

Before dispatch, the module is run on the test bench through the standard goods test. For a spindle module, the meaningful evidence is behaviour across its working range rather than a power-on light, and the bench run is organised to show the unit working, with a test video available when the buyer asks for one.

A failed H022 returned for repair is diagnosed to stage level first. Spindle modules that fail only under thermal load are a known bench case: the diagnosis has to reproduce the load condition, which is precisely what separates a bench finding from a guess.

Ordering A06B-6222-H022

Quote A06B-6222-H022 exactly, and verify the H022 against the label twice — its servo sibling wears a nearly identical face. Name the machine, the spindle symptom as displayed, and the spindle motor's number if it can be read. State the condition accepted and whether the H015 sibling is also in question; that is everything the desk needs for this number.
