The FANUC A06B-6117-H211 is an Alpha i SV 160/160 dual-axis servo amplifier module designed for FANUC CNC machine tool systems.

This high-power servo amplifier controls two servo axes within the FANUC Alpha i drive architecture. It provides stable current control, precise position regulation, and reliable feedback processing for demanding CNC machining applications.

The A06B-6117-H211 supports two servo motor channels, with both axes rated for 160 A output capability. It receives DC bus power and provides controlled AC output for compatible FANUC Alpha i servo motors.

The module integrates digital servo control technology with encoder feedback processing and built-in protection functions including overcurrent, overvoltage, and thermal monitoring.

This amplifier is commonly used in CNC machining centers, large machine tools, milling systems, and other industrial equipment requiring high-power synchronized servo motion.

Before replacement, confirm the CNC controller model, servo motor specifications, axis assignment, encoder wiring, DC bus configuration, and stored servo parameters.

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