Fanuc ai Servo Amplifier 200VAC-input A06B-6117-C155

🔧 A06B-6117-C155 — Description

The A06B-6117-C155 is a FANUC αi (Alpha i) series servo amplifier internal unit (C-type) used in a dual-axis, higher-capacity servo amplifier module.

⚙️ Identification

• Manufacturer: FANUC

• Series: αi Servo Amplifier Series

• Type: Internal unit / configuration (C-version)

• Associated Complete Module:
  👉 A06B-6117-H155

• Servo Class: αiSV 160/160 (dual-axis amplifier)

🔍 What “C155” Represents

FANUC part structure:

• H155 → Complete dual-axis servo amplifier

• C155 → Internal drive/power unit inside that amplifier

👉 So, A06B-6117-C155 is the internal unit of a dual SV160 class servo amplifier.

⚡ Technical Overview (SV 160/160 Class)

Typical characteristics:

• Configuration: Dual-axis (2 motors)

• Power Class: ~2 × 11 kW (approx., per axis)

• Input Supply: 200–240V AC (3-phase)

• Output Current: ~160A per axis

• Control Modes:

  • Position

  • Speed

  • Torque

• Communication: FANUC FSSB (fiber optic servo bus)

• Cooling: Forced air (fan-cooled)

🚀 Key Features

• Drives two high-power servo motors simultaneously

• Designed for heavy-duty, high-load applications

• Fast dynamic response with high torque output

• Compact dual-axis module reduces cabinet space

• Built-in protections (overcurrent, overload, temperature, etc.)

🏭 Applications

Used in:

• Large CNC machining centers

• Gantry and double-column machines

• Heavy-duty milling and boring machines

• Industrial automation with high load axes

🧠 Simple Explanation

• C155 = internal electronics (core drive unit)

• H155 = full dual-axis amplifier (SV160 / 160-160 class)

👉 It’s the “power core” of a very high-capacity 2-axis FANUC servo drive.

🔄 Context Comparison (Dual-Axis Range)

• C153 → 40/40 (medium)

• C154 → 80/80 (high)

• C155 → 160/160 (very high)
