The FANUC A06B-6079-H205 is an Alpha Series SVM2-20/40 dual-axis servo amplifier module designed for FANUC CNC machine tool systems.

This amplifier module provides control for two servo axes within a FANUC Alpha drive architecture. It receives DC bus power and controls compatible FANUC Alpha servo motors through digital servo communication and encoder feedback.

The SVM2-20/40 configuration supports two different servo output channels, with the L axis rated at 5.9 A and the M axis rated at 12.5 A. The module is suitable for CNC machining centers, milling machines, turning centers, and other industrial machine tools requiring reliable servo axis control.

The A06B-6079-H205 integrates protection functions including overcurrent, overvoltage, and thermal monitoring to improve system reliability during machine operation.

Before replacement, verify the CNC system model, servo motor type, encoder feedback wiring, axis assignment, jumper settings, and original 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.
