The FANUC A06B-6220-H026 RU is a high-efficiency dual-axis αiSV servo amplifier, specifically engineered for CNC applications requiring precise, high-speed motion control in compact spaces. Part of FANUC’s advanced A06B-6220 series, this model delivers robust torque performance, minimal latency, and seamless communication through FSSB (Fiber Optic Serial Servo Bus).
Ideal for integration with FANUC 30i/31i/0i-F and Power Motion i systems, this unit offers reliable dual-axis control while maintaining thermal stability, diagnostic transparency, and motor matching versatility—making it an industry favorite for high-speed machining, axis synchronization, and automation retrofits.
Dual-Axis Amplification – Controls two servo motors in parallel, reducing system footprint and cost
FSSB Communication Interface – High-speed, noise-immune fiber optic protocol ensures real-time control
Advanced Regenerative Braking – Built-in circuitry handles motor deceleration energy safely and efficiently
Built-In Diagnostic LED Panel – Supports quick error isolation aligned with standard FANUC drive alarm list
Japan Original Build – Engineered and manufactured to FANUC’s strict OEM standards
Fan Monitoring & Thermal Overload Protection – Reliable in 24/7 production environments
This drive is widely deployed in:
CNC machining centers with dual-axis servo needs
Multi-axis CNC lathes and robotic arms
Industrial automation lines requiring synchronized axis control
OEM systems utilizing αiS series servo motors
The dual-axis capability enables streamlined cabinet layouts, especially in compact machines requiring X-Y or U-V motion control from a single unit.
| Model | Axis Support | Communication | Space Efficiency | Use Case |
A06B-6220-H011 | Single-axis | FSSB | Larger footprint for 2 axes | Low-power single-axis motion |
A06B-6220-H026 RU | Dual-axis | FSSB | Saves cabinet space | Dual-motor CNC axis control |
If your CNC or automation system requires two servo axes with minimal wiring and better spatial efficiency, the H026 RU is the superior choice.
This unit supports a wide range of diagnostics that can be tracked via FANUC’s drive alarm list, including:
| Alarm Code | Description |
AL-01 | Output overcurrent |
AL-04 | Cooling fan malfunction |
AL-06 | Braking resistor failure |
AL-12 | FSSB communication fault |
AL-20 | Internal CPU or memory error |
AL-30 | Thermal overload (servo amplifier) |
These alarms display both via on-unit LEDs and within the connected CNC interface, allowing for fast and precise troubleshooting.
