⚙️ Full Technical Description

👉 A06B-6114-C201 = Alpha i Spindle Amplifier (SPM-11 type)

• Series: Alpha i (αi) Spindle Drive System
• Type: Spindle Amplifier / Spindle Drive
• Function: Drives spindle motor (main spindle or C-axis)
• Model Class: SPM-11 (low capacity spindle amplifier)

---

⚙️ What It Does

This module:

• Drives the main spindle motor or C-axis motor
• Controls spindle speed, torque, and orientation
• Supports rigid tapping (synchronous motion with servo axes)
• Communicates with FANUC CNC via FSSB (fiber optic servo bus)

👉 In simple terms:
It controls the rotation and power of the CNC spindle (cutting tool or workpiece rotation).
