The FANUC A06B-6117-H153 Alpha i SV 20L HRV3 servo amplifier module is designed for high-precision single-axis motion control in FANUC CNC systems.

This amplifier uses HRV3 (High Response Vector Control 3) technology to deliver fast dynamic response, smooth speed regulation, and accurate positioning for compatible FANUC Alpha i servo motors. It is suitable for machine tools requiring stable servo performance during continuous production.

The module operates from a 283–339 VDC DC bus and provides digital servo control through the FANUC CNC architecture. Integrated encoder feedback processing enables precise synchronization between the CNC controller and servo motor.

Designed for industrial control cabinets, the A06B-6117-H153 incorporates comprehensive protection against overcurrent, overvoltage, and overheating to improve long-term operating reliability.

This product is a servo amplifier module only. It is not a servo motor, CNC controller, spindle amplifier, power supply module, or variable frequency drive.
