The A06B‑6130‑H002 servo amplifier is a single‑axis AC servo drive designed for Fanuc Beta i and Alpha i servo motor families, commonly used as a Beta 4 / Beta 8 motor amplifier in multi‑axis CNC and robotics setups. It accepts 200–240 V AC 3‑phase input at 50/60 Hz and converts this to controlled AC output for one servo motor, with maximum 6.8 A motor current for smooth, high‑precision positioning.
This Fanuc servo drive uses fiber‑optic FSSB (Fanuc Serial Servo Bus) interface to exchange real‑time feedback and commands with the CNC or robot controller, enabling fast response, high‑resolution tuning, and daisy‑chain expansion of multiple axes. The module includes built‑in overcurrent, overvoltage, and overtemperature protection to safeguard the drive and motor in heavy‑duty or continuous‑cycle environments.
Physically, the A06B‑6130‑H002 is a compact panel‑mount servo amplifier suitable for constrained CNC cabinets and robot‑arm enclosures. It is typically sold with a 1–2‑year warranty for new units and 3‑month warranty for tested or used drives. With in‑stock availability at many distributors, it is a popular choice for CNC rebuilds, axis‑drive replacements, and retrofit projects in milling, turning, and material‑handling automation.
