FANUC A06B-6111-H015#H550 αi Spindle Amplifier Module – Stable 400V-class Drive for Modern Machine Tools

• Warranty: 365 days

• Delivery: 1 week if in stock; no more than one month at the latest

• Payment: 50% advance payment; full payment prior to delivery

• Express options: FedEx, UPS, DHL

• 400V-class αi spindle drive (#H550): Suited for 380–480 VAC plants, typically used on mid-range machining centers and lathes.

• High-speed fiber-optic CNC link: FANUC serial fiber interface ensures responsive speed control, spindle orientation, and rigid tapping support.

• Efficient power section: Optimized switching and heat dissipation to keep cabinet temperatures stable and energy use under control.

• Comprehensive protections: Overcurrent, overvoltage, undervoltage, and thermal safeguards, plus ground fault and alarm diagnostics.

• Regeneration-ready: Supports dynamic braking; external braking resistor can be applied where required by duty cycle.

• Service-friendly design: Front-access terminals, status LEDs, and clear alarm codes reduce troubleshooting time.

• Proven ecosystem compatibility: Works with FANUC αi spindle motors and standard FANUC CNCs used across global production lines.

You’ll typically see the A06B-6111-H015#H550 in:

• CNC machining centers dealing with steel, aluminum, and composite cutting where steady spindle torque is critical

• CNC lathes and turn-mill machines needing accurate spindle orientation for live tooling

• Grinding machines requiring smooth, low-vibration spindle speed control

• Production lines with FANUC CNCs standardizing on 400V-class drives

From my experience, shops upgrading older drives to this module often report cleaner starts, faster orientation, and fewer nuisance alarms when cabinet cooling is properly set.

• Reliability that reduces downtime: Robust protection and diagnostics; spare parts are widely available.

• Compatibility with FANUC ecosystems: Pairs with αi spindle motors and mainstream FANUC CNC controllers, easing commissioning.

• Energy and thermal efficiency: Helps maintain stable cabinet temperatures, which, in many cases, prolongs component life.

• Lower integration risk: Standard fiber-optic link and familiar parameter sets shorten changeover time for maintenance teams.

A maintenance lead in an automotive line told us they swapped to this H015 module on a twin-pallet machining center and noticed orientation consistency improve immediately, with less time spent chasing intermittent spindle alarms.

• Cabinet environment: Mount vertically in an IP-rated enclosure; ensure forced-air ventilation and unobstructed airflow around heatsinks.

• Power and grounding: Use 3-phase 380–480 VAC with dedicated PE ground. Keep motor leads short, shielded where applicable, and segregated from signal cables.

• Braking resistor: Size and mount an external resistor if your duty cycle demands frequent rapid decel; follow FANUC recommendations.

• Fiber link handling: Route fiber-optic cables with gentle bends; keep clear of high-voltage conductors to minimize noise.

• Parameter management: Back up CNC parameters and spindle settings before replacement; confirm hardware suffix compatibility (#H550) to avoid mismatch.

• Routine checks: Quarterly dust cleaning, terminal torque checks, fan inspection, and verifying alarm history. Firmware/parameter updates should follow OEM guidance.

• Safety: Lockout/tagout, discharge DC bus fully, and confirm absence of residual voltage before servicing.

• Certifications: CE marked; UL recognition for components; RoHS compliance on most recent builds.

• Manufacturing quality: Built under stringent quality systems (ISO 9001 at manufacturing sites).

• Warranty: 365-day coverage from our side for repair/replace, subject to standard terms.

• FANUC αi spindle motors matched to the H015 rating

• Braking resistor assemblies sized for your deceleration profile

• Fiber-optic link cables for CNC connection (FANUC spec)

• Shielded motor power cables and grounding kits

• Cooling fans and filter media for cabinet airflow
