Description
🔧 Model Overview
A06B-6114-C201 is a FANUC Alpha i (αi) spindle amplifier module — not a servo amplifier. It is specifically designed to drive C-axis / spindle motors in CNC machines.
⚙️ 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).
🔩 Key Specifications (Typical)
- Model Type: SPM-11
- Capacity: Small spindle drive (low power range)
- Input Voltage: ~283–339 V AC (3-phase typical FANUC range)
- Output Voltage: ~200–240 V
- Cooling: Fan-cooled
- Feedback: Supports spindle encoder for orientation control
🏭 Applications
- CNC lathes (main spindle or C-axis control)
- CNC machining centers
- Milling machines
- Machines requiring low to medium spindle power
🔍 Key Features
- ✔ Spindle control (not axis servo control)
- ✔ Supports rigid tapping
- ✔ Precise speed & torque control
- ✔ Compact module for small spindle motors
