The FANUC A06B-6222-H002 is a compact, high-performance spindle amplifier module from FANUC's advanced αiSP-B series. This unit is specifically designed to drive spindle motors in CNC machine tools, providing precise speed and torque control for rotating cutting tools, workpieces, or other spindle-based applications.
As a 200V input series spindle amplifier, the A06B-6222-H002 (also designated as the αiSP 2.2-B model) is part of FANUC's Level-up αi-B amplifier family. This series employs a modular structure that is thinner, conserves more space, outputs less heat, and saves more energy compared to conventional amplifier designs. The amplifier features FANUC's latest low-loss power devices and a newly developed high-efficiency radiator, delivering exceptional power density in a minimal footprint.
The A06B-6222-H002 is built with power regeneration as standard, contributing to significant energy savings across all models from small to large capacity. Its rugged construction and comprehensive protection features ensure reliable operation in demanding manufacturing environments, from small job shops to high-volume production facilities.
The module is TÜV Rheinland certified under certificate number R 50210669, having fulfilled safety standard EN 61800-5-1:2007, confirming its compliance with international adjustable speed electrical power drive system safety requirements.

- Ultra-compact design: At just 60mm wide, this amplifier features a slim, finless design that significantly reduces cabinet space requirements compared to traditional spindle drives.
- Energy-saving operation: All models use power regeneration as standard, converting braking energy back to usable power. The latest low-loss power devices minimize heat generation, reducing cooling requirements and operating costs.
- Simplified cabling: FSSB (FANUC Serial Servo Bus) enables both servo and spindle amplifiers to be connected to the CNC using only optical fiber cables, dramatically reducing wiring complexity and installation time.
- Reduced maintenance downtime: The radiator cooling fan motor can be replaced without removing the unit from the power magnetics cabinet. Connectorized power lines allow for faster amplifier replacement and eliminate the need for reference position return after replacement.
- Smart troubleshooting: The built-in smart troubleshooting function allows diagnostic information to be checked directly on the CNC screen, helping operators quickly locate the cause of spindle alarms.
- Preventive maintenance capability: Includes a leakage detection function that can automatically detect signs of insulation degradation in motors or power lines with high accuracy, enabling proactive maintenance.
- Absolute position backup: The system supports Absolute Pulsecoder with a built-in backup capacitor, maintaining absolute position detection for approximately 10 minutes so that reference position return is unnecessary after amplifier or feedback cable replacement.
