⚙️ Identification
-
Manufacturer: FANUC
-
Series: αi Servo Amplifier Series
-
Type: Internal unit / configuration (C-version)
-
Associated Complete Module:
👉 A06B-6117-H156 -
Servo Class: αiSV 160/80 (dual-axis amplifier)
🔍 What “C156” Represents
FANUC naming logic:
-
H156 → Complete servo amplifier (dual-axis)
-
C156 → Internal drive/power unit inside that amplifier
👉 So, A06B-6117-C156 is the internal unit of a dual-axis amplifier with unequal capacities (160/80).
⚡ Technical Overview (SV 160/80 Class)

-
Axis 2: ~5.5 kW (SV80)
-
-
Input Supply: 200–240V AC (3-phase)
-
Output Current:
-
High-current channel (~160A class)
-
Medium-current channel (~80A class)
-
-
Control Modes:
-
Position
-
Speed
-
Torque
-
-

🚀 Key Features
-
Drives two servo motors with different power requirements
-
Ideal for machines with uneven axis loads (e.g., heavy Z-axis + lighter X/Y)
-
Compact and space-saving dual-axis design
-
High efficiency with regenerative energy handling
-
Built-in diagnostics and protection systems
🏭 Applications
Used in:
-
CNC machining centers with mixed-load axes
-
Machines where one axis carries higher load (e.g., vertical axis)
-
Automation systems requiring asymmetric motor control
-
Gantry or hybrid motion systems
🧠 Simple Explanation
-
C156 = internal electronics (drive unit)
-
H156 = full amplifier (dual SV160 + SV80)
👉 It’s the core of a dual-axis FANUC drive where one motor is powerful and the other is medium-sized.
🔄 Context Comparison (Dual-Axis Series)
-
C153 → 40/40 (medium/medium)
-
C154 → 80/80 (high/high)
-
C155 → 160/160 (very high/very high)
-
C156 → 160/80 (mixed capacity)
