The FANUC A06B-6117-H106 is an Alpha i Series αi SV 160 single-axis servo amplifier module designed for FANUC CNC machine tool systems.

This amplifier provides high-current servo control for one CNC machine axis and is designed to drive compatible FANUC Alpha i servo motors with precise positioning, speed regulation, and torque control.

The A06B-6117-H106 operates with a DC bus input of 283 to 339 VDC and provides up to 160 A rated output current for demanding machining applications. It integrates digital servo control technology, encoder feedback processing, and protection functions for reliable CNC operation.

This module is commonly used in CNC machining centers, milling machines, turning machines, and other industrial machine tools requiring stable servo axis performance.

Before replacement, verify the CNC controller model, servo motor specification, encoder feedback cable, axis assignment, parameter backup, and amplifier configuration.

This product is a servo amplifier module only. It should not be described as a CNC controller, servo motor, spindle amplifier, power supply module, or standalone motion controller.
