The A06B‑6134‑H303#A module is a triple‑axis servo + spindle drive designed for Fanuc Beta‑i servo and spindle motors. It integrates three feed‑axis amplifiers (L, M, N) and a spindle‑axis amplifier in a single cabinet‑mount unit, reducing panel space and wiring while maintaining independent control of each axis. The amplifier uses 200–240 V AC 3‑phase input at 50/60 Hz and can deliver up to 63 A of total current, with 13 A per individual axis for smooth, high‑speed motion and strong spindle torque.
This Beta‑i servo/spindle module supports standard Fanuc servo and spindle buses, enabling precise current‑loop, speed‑loop, and position‑loop control as well as spindle‑orientation and constant‑power operation. It features overcurrent, overvoltage, and overtemperature protection, along with built‑in diagnostics that display alarm codes via LEDs on the front panel, simplifying troubleshooting and maintenance. The rugged, panel‑mount construction makes it suitable for continuous‑duty CNC environments such as milling centers, turning lathes, and automated production lines.
Physically, the A06B‑6134‑H303#A measures approximately 380 mm × 260 mm (L × H) and weighs about 11 kg, allowing it to fit in standard industrial control cabinets. It is manufactured by Fanuc in Japan and typically comes with a 1–2‑year warranty for new units and 3‑month warranty for used or tested modules. With in‑stock availability at many CNC‑parts suppliers, it is a popular choice for CNC rebuilds, drive‑rack upgrades, and retrofits where triple‑axis servo performance and spindle control are required.
