Description
🔧 Product Description — FANUC A06B-6117-H208
FANUC A06B‑6117‑H208 is a 2‑axis high‑performance servo amplifier module from the FANUC Alpha i (αi) servo drive family, used in CNC and industrial automation motion control systems.
⚙️ What It Is
👉 A06B‑6117‑H208 = Dual‑Axis Alpha i Servo Amplifier (Model AiSV‑40/80)
- Series: Alpha i (αi) Servo System
- Type: AC servo drive / amplifier
- Axes: 2‑axis (dual channels)
- Purpose: Controls and powers two FANUC servo motors for coordinated motion.
This module typically interfaces with a FANUC CNC controller using the proprietary fiber optic servo bus and provides high‑precision motion control for machine tool axes or other automated machinery.
🔩 Key Technical Specifications
- Model Class: AiSV‑40/80 — one channel rated ~40 class, the other ~80 class (unequal capacity).
- Rated Input Voltage: ~283–339 V AC (3‑phase).
- Power Rating: ~10 kW total.
- Max Output Voltage: ~240 V.
-
Rated Output Currents:
• L‑axis: ~13 A
• M‑axis: ~19 A - Cooling: Forced‑air fan cooled (typical for Alpha i drives).
🏠Typical Applications
This amplifier module is designed for use in:
- CNC machining centers and milling machines
- CNC lathes and turning centers
- Multi‑axis industrial automation systems
- Robotics and any motion control requiring two controlled axes with different load requirements
đź§ Simple Explanation
👉 A06B‑6117‑H208 is a powerful dual‑axis servo amplifier that supplies precise electrical power and motion control to two servo motors — one medium‑load axis and one heavier‑load axis — typically used in CNC machine tools and automated systems.
