FANUC A06B-6110-H011 Power Supply Module – Stable 200V-class backbone for αi servo/spindle systems
The FANUC A06B-6110-H011 is a Power Supply Module from the αi series (often referred to as PSM-11). From my experience, this unit is a dependable “front end” for 200V-class FANUC αi servo and spindle amplifiers, providing the regulated DC link and regenerative handling your machine needs to run cleanly and keep downtime in check. You might notice that it drops in neatly when upgrading or replacing older α power supplies, which makes retrofit work much easier in many cases.

Application Fields
This module is commonly used in FANUC-based machining centers, CNC lathes, drilling/tapping lines, grinding machines, and small robotized cells. One thing I appreciate is how it keeps mixed servo/spindle setups stable on 200V-class machines—especially on older lines where you want modern reliability without a total cabinet redesign.
- OEM machine builds and lifecycle replacements on FANUC α/αi platforms
- Retrofit projects upgrading power sections while retaining existing CNC and motors
- High-duty-cycle cells that need reliable regenerative handling
- Service spares to shorten unplanned downtime windows
Advantages & Value for Procurement
- Reliability: Proven αi architecture that, in most cases, runs for years with minimal intervention.
- Compatibility: Works with matching FANUC αi servo/spindle modules, reducing integration friction.
- Cost control: Drop-in form factor helps avoid cabinet rework and long commissioning time.
- Serviceability: Clear alarm behavior and accessible terminals make troubleshooting faster.
- Availability options: Stock and expedited logistics (FedEx/UPS/DHL) when downtime is critical.
Installation & Maintenance
For installation, I typically recommend a clean, sealed control cabinet (IP54 or better) with vertical mounting and clear airflow. Keep power and signal wiring separated, bond PE/ground with low impedance, and follow torque specs on DC link and mains terminals. If your cycle has heavy decel, plan for an external regenerative resistor sized to the duty.
- Environment: 0–55°C, non-condensing; avoid conductive dust and oil mist.
- Ventilation: Maintain top/bottom clearance; ensure cabinet fans/filters are clean.
- Wiring: Use appropriately rated cables; verify phase rotation and correct DC link polarity to amplifiers.
- Safety: Lockout/tagout; wait for DC bus discharge before servicing (indicator LEDs to confirm).
- Maintenance: Periodic dust cleaning, terminal retorque checks, and visual inspection for heat discoloration.
- Software: The PSM itself typically needs no firmware updates; ensure CNC/drive software compatibility when replacing legacy units.
Quality & Certifications
FANUC power modules of this series are commonly CE-marked and UL recognized, and in many cases compliant with RoHS depending on production year. The manufacturer’s standard quality processes apply to αi hardware. Our coverage for this item is a 365-day warranty, and we support both new and professionally refurbished supply options when available.
Related/Supporting Components
To complete a system build or replacement, customers typically pair the A06B-6110-H011 with:
- FANUC αi Servo Amplifier Modules (e.g., A06B-6114-Exxx series, matched to axis current)
- FANUC αi Spindle Amplifier Modules (e.g., A06B-6120-Exxx series, matched to spindle motor)
- External regenerative resistor units where required by duty cycle
- Approved mains filters, circuit protection, and panel accessories for EMC and safety
“Swapped the H011 into a 3-axis cell with mixed servo/spindle loads. It was a clean drop-in; regen stayed cool, and nuisance over-voltage alarms disappeared after setting the external resistor correctly.”
