Fanuc ai Servo Amplifier 400VAC-input A06B-6124-C209

🔧 A06B-6124-C209 — Description

The part number A06B-6124-C209 is a FANUC Alpha i series servo amplifier module (drive) used in CNC machines and industrial automation systems.

📌 Basic Identification

• Manufacturer: FANUC
• Series: A06B-6124
• Type: AC Servo Amplifier (Drive)
• Configuration: Dual-axis (2-axis)
• Class: Alpha i SVM2 series (High Voltage)

⚙️ Function

This module is responsible for:

• Driving two servo motors simultaneously
• Controlling position, speed, and torque
• Converting DC bus power into controlled AC output

👉 In simple terms:
It is the power + control unit for CNC machine axes.

🧩 Model Details (C209)

The C209 variant corresponds to the same class as the widely documented H209 model, which defines its technical level:

• Equivalent Model: SVM2-80/80HVi
• Type: High-power dual-axis servo amplifier
• Voltage Class: ~400–480V system
• Application Level: High-capacity CNC axis control

➡️ Example (H209 reference):

• 2-axis Alpha i servo module, model SVM2-80/80HVi
• Dual-axis amplifier with ~18.2A output per axis

👉 The “C209” suffix typically indicates:

• Hardware revision / region-specific version
• Minor internal differences
• Same functional category as H209

🔌 Typical Technical Characteristics

• Axes: 2 (L & M channels)
• Voltage: 3-phase ~400–480V AC system
• Current Capacity: ~18A per axis (class reference)
• System: FANUC Alpha i servo system
• Control Compatibility: FANUC CNC (0i, 16i, 18i, 21i, etc.)

🏭 Applications

Used in:

• CNC machining centers
• CNC lathes
• Heavy-duty axis control systems
• Industrial automation & robotics

⚠️ Important Notes

• ❗ This is NOT a motor → it is a servo amplifier (drive)
• Always match the full part number (C209) when replacing
• Cross-compatibility with H209 is common, but must be verified

🧠 Simple Understanding

• Servo motor → produces motion
• Servo amplifier (this unit) → controls & powers the motor
