🔧 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.
