FANUC A06B-6130-H003 Servo Amplifier Module – Reliable axis drive for FANUC CNC machines

The FANUC A06B-6130-H003 is a genuine FANUC servo amplifier module designed for CNC axis control in production machinery. From my experience, it’s typically deployed with FANUC 0i and 30i/31i/32i series controls and paired with a FANUC Power Supply Module (PSM/PSMi) over the DC link bus. You might notice that it fits the common “booksize” amplifier footprint, which makes cabinet planning straightforward and keeps retrofits tidy. If your goal is to stabilize axis motion, clear servo alarms, or bring a down machine back online quickly, this model seems to be a very solid choice.

Key Features

• Genuine FANUC axis drive – Built to work seamlessly with FANUC CNCs and matched servo motors, reducing tuning headaches.
• FSSB fiber-optic interface – High-speed digital link to the CNC for tight position/velocity loops and quick diagnostics.
• Works on the DC link from FANUC PSM/PSMi – No direct AC mains to the amplifier; improves cabinet safety and simplifies wiring.
• Diagnostic LEDs and alarm codes – Faster troubleshooting on the shop floor; in many cases you can pinpoint wiring or overload issues in minutes.
• Supports serial encoder feedback – Compatible with the common FANUC serial feedback used on matched servo motors (absolute or incremental setups).
• Compact, “booksize” form factor – Saves cabinet space and makes multi-axis layouts cleaner.
• Protection features – Overcurrent, overheat, and short-circuit detection help protect motors and upstream power modules.

Technical Specifications

Application Fields

This model is commonly used in CNC machining centers, turning centers, grinders, and precision drilling/tapping machines. You’ll also find it in retrofits where keeping legacy FANUC motion performance is a priority. One thing I appreciate is how it drops into existing cabinets with minimal rewiring when you’re already on a FANUC PSM/PSMi DC bus and FSSB.

• Metal cutting and mold/die machining
• High-speed pick-and-place and indexing axes
• Precision grinding and honing lines
• OEM machine builds using FANUC CNC platforms

Advantages & Value

• Reliability – In many cases, swapping to a like-for-like A06B-6130-H003 clears axis servo alarms immediately, reducing downtime risk.
• Compatibility – Seamless with FANUC CNCs, FSSB, and matched FANUC servo motors; no odd adapters or custom firmware.
• Lower total cost – Faster install and less tuning typically translate to real labor savings on urgent repairs.
• Support – We assist with part matching (PSM capacity, motor pairs, fiber lengths) and basic alarm interpretation to speed commissioning.

A shop-floor example: a customer with a 3-axis vertical mill reported intermittent “overcurrent” faults on one axis. After replacing the amplifier with A06B-6130-H003 and verifying fan airflow, the machine returned to stable operation within the same shift—no further nuisance stops over the next month.

Installation & Maintenance

• Cabinet & mounting – Install on a rigid backplate inside an industrial cabinet (IP54 or better is typical). Keep cable bends gentle and segregate motor power from signal/fiber routes.
• Power & grounding – Connect via the DC link bus to the FANUC power supply module; bond the PE ground with low impedance. Use factory torque values on bus bars and terminals.
• Ventilation – Maintain unobstructed front-to-back airflow with clean fan filters; avoid hot spots near transformers or braking resistors.
• Safety – Lock-out/tag-out mains. After power-down, allow DC link capacitors to discharge fully before servicing. Use ESD protection when handling fiber boards and connectors.
• Routine care – Quarterly dust cleaning, check fan operation, inspect terminals for discoloration/looseness, and review CNC error logs. Firmware/config backups are recommended before changes.

Quality & Certifications

• Manufacturer certifications typically include CE and UL compliance
• RoHS conformity for electronic assemblies where applicable
• Manufactured under ISO 9001 quality systems (FANUC)
• Warranty: 365 days coverage

Frequently Paired Components

• FANUC Power Supply Module PSM/PSMi (e.g., A06B-6140-Exxx variants matched to machine load)
• FANUC servo motors with serial feedback (matched capacity and brake options)
• FSSB fiber-optic cables and DC link bus bars for multi-axis configurations
