A06B-6079-H201 belongs to FANUC Alpha servo drive system, dual-axis integrated servo amplifier SVM2-12/12. It takes 283–325V DC link power from the power supply module, converts DC to three-phase AC for L and M axis servo motors. Rated output current 3.0A for each axis, max output voltage 230V AC, max power 1.5kW per axis. It uses sine-wave PWM vector control for high-precision positioning and smooth motion.

This module connects to CNC mainboard via optical fiber FSSB high-speed serial bus, transmitting position command and encoder feedback data. Front panel LED indicators display power ready and alarm codes for quick on-site fault diagnosis. It supports absolute and incremental encoder feedback, brake control signal output for servo motors with holding brake. Multiple axes can be assembled together in one drive rack matched with FANUC power supply module.

Comprehensive protection includes overcurrent, overload, overvoltage, undervoltage, amplifier overheat, encoder failure, short circuit and earth fault protection. IP20 protection grade, cabinet rack mounting, operating temperature range 0~55℃.

A06B-6079-H201 is discontinued legacy FANUC CNC spare part. Many old CNC machine tools still run Alpha servo systems. When the original servo amplifier fails, replacing it with identical A06B-6079-H201 can reuse existing drive rack, DC bus wiring, motor cables and CNC parameters. Technicians install the module in rack, check optical FSSB link, test motor JOG operation and verify axis positioning, so the CNC servo motion system resumes operation and reduces downtime.

Before shipment, every A06B-6079-H201 undergoes comprehensive functional inspection including power-on self-test, FSSB optical communication test, output waveform test, encoder feedback verification and protection function simulation. All products come with 12-month warranty. Our automation technical team provides remote support for rack installation, wiring guidance, CNC parameter backup and alarm fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, A06B-6079-H201 is reliable spare dual-axis servo amplifier for legacy FANUC Alpha CNC systems. It restores two-axis servo positioning function, extends service life of machine tool assets and avoids high-cost whole drive system renovation.
