👉 So, A06B-6117-C154 is the internal unit of a dual 80-class servo amplifier.

⚡ Technical Overview (SV 80/80 Class)

Typical characteristics:

• Configuration: Dual-axis (2 servo motors)

• Power Class: ~2 × 5.5 kW (approx., per axis)

• Input Supply: 200–240V AC (3-phase)

• Output Current: ~80A per axis

• Control Modes:

  • Position

  • Speed

  • Torque

• Communication: FANUC FSSB (fiber optic servo bus)

• Cooling: Forced air (fan-cooled)

🚀 Key Features

• Controls two high-power servo motors simultaneously

• Compact design for multi-axis CNC systems

• High torque and fast response

• Built-in diagnostics and protection features

• Efficient regenerative energy handling

🏭 Applications

Used in:

• CNC machining centers (multi-axis)

• Heavy-duty automation systems

• Gantry machines and large motion systems

• Robotics requiring dual synchronized axes

🧠 Simple Explanation

• C154 = internal electronics (drive unit)

• H154 = full amplifier (dual SV80 / 80/80 class)

👉 It’s the core of a powerful 2-axis FANUC servo drive used when two motors need strong and synchronized control.

🔄 Context Comparison

• C153 → Dual 40/40 (medium power)

• C154 → Dual 80/80 (higher power)

• C105 → Single SV80

• C106 / C109 → Single-axis high power
