Fanuc ai Servo Amplifier 200VAC-input A06B-6114-C205

🔧 Model Overview

A06B-6114-C205 is a FANUC Alpha i (αi) spindle amplifier module, designed to drive and control CNC spindle motors.

⚙️ Full Technical Description

👉 A06B-6114-C205 = Alpha i Spindle Amplifier (SPM-22 type)

• Series: Alpha i (αi) Spindle System
• Type: AC Spindle Amplifier / Drive
• Model Class: SPM-22 (medium-high power spindle drive)
• Function: Controls main spindle or C-axis motor

⚙️ What It Does

This module:

• Drives the spindle motor (tool rotation or workpiece rotation)
• Controls speed, torque, and spindle orientation
• Enables rigid tapping (synchronized spindle + axis movement)
• Communicates with FANUC CNC via FSSB (fiber optic bus)

👉 In simple terms:
It controls how fast and how powerfully the spindle rotates in a CNC machine.
