FANUC Spindle Amplifier Drive Module A06B-6140-H015

What A06B-6140-H015 is

A06B-6140-H015 is listed by the seller's shop as a spindle amplifier drive module — an A06B-family module dedicated to the spindle drive role. Unlike the combined units on the same shelf, this number carries one role: it drives the spindle motor, under the control's command, fed from the shared power supply.

On the spindle amplifiers page it sits beside the A06B-6222-H022 AiSP module — two spindle modules from different module generations — and the A06B table keeps both visible so a cabinet's modules can be matched by group as well as by role.

Where A06B-6140-H015 works

The module's working partners are the control above it and the spindle motor below it. Spindle faults divide between those three addresses, and the presentations overlap: a motor with failing insulation and an amplifier with a weak stage can produce near-identical trips. The inquiry that names the symptom precisely — trip at start, trip under cut, orientation failure, alarm code as displayed — is the one that gets a useful first answer.

The desk's routine for this number includes asking what the sibling servo modules show. A clean servo side with a tripping spindle side is one story; a cabinet-wide disturbance after a supply event is another, and the second story starts at the power supply page, not here.

The single-phase input is this module's reason to exist, so the inquiry should confirm the cabinet's supply arrangement in words — single-phase or three-phase — rather than leaving it to be inferred from the machine's size. Machines in the same control class were wired both ways, and the module that fits the number but not the supply is the classic wrong shipment on this shelf.

Condition options for A06B-6140-H015

Shelf condition for this number is stated on inquiry, across the seller's normal range. The listing establishes what the unit is; the answer establishes what the unit on the shelf is — new, new-surplus or used — and the buyer decides against that statement plus the test evidence offered.

Used spindle modules follow the used FANUC parts framework: stated condition, bench test before dispatch, the seller's 3-month used-parts warranty, and a test video on request. A buyer whose machine cannot stop twice should ask for the video by name; it is the cheapest insurance in the whole transaction.

Testing A06B-6140-H015 before dispatch

The module passes the standard bench gate before dispatch: powered, run and observed on the test bench, not merely inspected. Spindle modules earn particular attention to load behaviour, because the fault that took the old unit out usually appeared under cut, not at idle.

The repair service takes failed units of this number on the same terms as the rest of the A06B family: diagnosis to the faulty stage, then a repair priced on the finding, with the shelf unit as the standing alternative the buyer can choose instead.

Ordering A06B-6140-H015

Quote the complete number — A06B-6140-H015 — with the machine named and the spindle symptom written as the control displayed it. Add the spindle motor's number when reachable, and the condition you will accept. If the order is urgent because the machine is down, say that too; the desk sequences testing and dispatch questions differently for a stopped machine than for a spare-parts shelf.
