FANUC A06B-6090-H006 AC Servo Amplifier Unit — Precision Drive Control for CNC Machine Tools

When a servo amplifier fails on the shop floor, every minute of downtime has a cost. The FANUC A06B-6090-H006 is a high-reliability AC servo amplifier unit built to keep your CNC systems running with the kind of motion precision that FANUC's engineering is known for worldwide. Stocked in both new and used (inspected) condition, this unit is ready to ship and fits directly into existing FANUC servo architectures — no costly system redesign required.

What This Unit Does

At its core, the A06B-6090-H006 functions as the bridge between your CNC controller's position commands and your servo motor's physical movement. It receives digital signals from the FANUC controller, conditions the power, and drives the AC servo motor with the precise current and timing needed to achieve accurate, repeatable axis positioning.

This makes it a load-bearing component in any machine tool or industrial automation setup running on FANUC's alpha-series servo platform. From multi-axis machining centers to turning centers and robotic systems, the servo amplifier is what keeps motion smooth, controlled, and consistent — cycle after cycle.

Built to FANUC's Industrial Standard

FANUC manufactures its servo amplifier series to strict performance tolerances at its facilities in Japan. The A06B-6090-H006 is no exception — it's designed from the ground up to integrate with FANUC's own CNC and servo motor ecosystems, which means you get predictable behavior, known fault codes, and straightforward diagnostics using existing FANUC tooling.

Key characteristics that make this unit a solid choice for replacement or spare stocking:

• Engineered for direct integration with FANUC alpha-series servo motors and associated CNC controllers
• Panel-mount form factor matches standard FANUC servo cabinet configurations, keeping installation fast and clean
• Internal protection circuits guard against overcurrent, overvoltage, and thermal overload — protecting both the amplifier and the connected motor
• CE certified, meeting relevant European electrical safety and EMC requirements
• Sourced from Japan, ensuring genuine FANUC build quality

Condition Options Explained

Not every application demands a factory-new unit. Here's how to think about your options:

New units arrive in original or equivalent protective packaging, unused, and are backed by a 12-month warranty. These are the right choice when you're building out a new system, stocking critical spares in a clean room environment, or when downtime risk from an aging component isn't acceptable.

Used units are sourced from decommissioned equipment and go through functional inspection and testing before they're offered for sale. They carry a 3-month warranty and are well-suited for situations where budget is a constraint or the machine being serviced has a shorter remaining service life. Every used unit we ship is confirmed operational before it leaves our facility.

Ordering, Shipping & Payment

We ship to destinations worldwide via DHL and FedEx. Most orders are dispatched within 0 to 3 working days from confirmed payment receipt. If you're purchasing multiple items, combined shipping is available — just mention it when you reach out.

Accepted payment methods:

• Bank Transfer (T/T) — accepted for all order values
• PayPal — accepted for orders of $500 or less
• Western Union — accepted for all order values

Import duties, customs taxes, and any other destination-country charges are the buyer's responsibility. If you're unsure about shipping costs or availability to your country, contact us before placing your order and we'll give you a clear answer.

Warranty Coverage & Return Policy

Returns are accepted in the following situations: the unit arrives damaged, incomplete, or significantly different from what was described; or the unit proves non-functional within 4 days of receipt. Items must be returned in their original condition with the warranty label intact, and return shipping costs are the buyer's responsibility.

We don't accept returns for change-of-mind purchases or for units ordered incorrectly. If you're unsure whether this part fits your application, reach out first — we'd rather help you confirm compatibility upfront than deal with a return.

Frequently Asked Questions

Q1: How does the A06B-6090-H006 differ from models like the A06B-6090-H005?

The H005 and H006 are both part of FANUC's 6090 servo amplifier series, but they differ in output specifications — most commonly in rated current capacity and the servo motor configurations they're designed to drive. The correct model for your system is determined by your servo motor's power requirements and the configuration specified in your machine's documentation. If you're unsure which variant applies to your setup, share your motor model and controller type with us and we can advise accordingly.

Q2: Will this amplifier work as a drop-in replacement in my existing FANUC system?

 In most cases where your current unit is an A06B-6090-H006, yes — provided the replacement unit is the same model number. FANUC's servo amplifier series is designed around consistent connector and mounting footprints within the same model family. That said, we always recommend confirming with your maintenance engineer or machine documentation before swapping components in critical production equipment.

Q3: Do you test used units before shipping?

Yes. Every used unit we list goes through functional inspection before it's made available for sale. We don't list units that haven't been verified operational. Used units are covered by a 3-month warranty from the date of receipt, giving you protection against latent faults that may not surface immediately.

Q4: How soon can I expect delivery after I pay?

Most orders ship within 0 to 3 working days of payment confirmation. International transit time via DHL or FedEx typically ranges from 3 to 7 business days depending on your location, though this can vary. If you have a hard deadline — for example, a production line that's down — let us know upfront and we'll advise on the most realistic timeline for your region.

Q5: Can I order in bulk, or is this only for single-unit purchases?

Both options are available. The minimum order quantity is just 1 piece, which suits maintenance teams sourcing a single replacement. For larger orders — whether for stocking spares across multiple machines or for resale purposes — we can accommodate higher volumes and are happy to discuss pricing and logistics for bulk arrangements. Reach out directly to discuss your specific quantity needs.
