The FANUC A06B-6058-H003 is a digital AC servo amplifier from the A06B-60 series, designed for small servo motors in FANUC Series 0i, 16i, 18i, 21i, and Power Mate CNC systems. It drives Model 1-0S or 2-0S AC servos with precise velocity and torque control, supporting high‑performance machining with fast response and smooth low‑speed operation. Rated for 200–230 VAC single/three‑phase input, it handles typical overloads and regenerative energy in feed axis applications.
This amplifier installs in the CNC electrical cabinet via DIN rail or panel mounting, connects to the motor via power and feedback cables, and interfaces with the CNC via backplane or ribbon cable. Features include digital velocity loop, regenerative resistor support, dynamic braking, parameter tuning via CNC parameters, and diagnostics through alarm codes/LEDs. It weighs 4.13 lbs (1.87 kg) and measures compactly for standard racks. Operating from 0–55°C, it meets industrial vibration/shock standards for machine tools.
Units are available new, refurbished, or repaired with 2-year warranties from suppliers, often as core exchanges to minimize downtime. Compatible with Alpha i, beta i motors and requires matching parameters for optimal performance.
