Description
A06B-6117-C103 is a unit specification code used by FANUC for a servo amplifier—not a complete amplifier itself.
🔹 What It Means
-
Part Number: A06B-6117-C103
-
Type: Unit specification (internal model code)
-
Series: αi (Alpha-i) servo amplifier system
👉 In FANUC terminology:
-
H103 = complete servo amplifier (order model)
-
C103 = internal configuration of that same amplifier
🔹 Related Servo Amplifier
-
Order model: A06B-6117-H103
-
Servo model: αiSV-20 (SV20)
So:
✅ C103 = internal version of H103 amplifier
🔹 Internal Configuration Details
For A06B-6117-C103, typical internal mapping is:
-
Servo type: αi SV-20
-
Wiring board: A16B-2203-0691
-
Control PCB: Not always separately listed (depends on revision)
🔹 Function (Same as H103 Amplifier)
The unit performs:
-
Servo current control
-
Speed and position control
-
Processing encoder feedback
-
Communication with CNC via FSSB (fiber optic link)
🔹 Where You See “C103”
You will usually find this number:
-
Inside FANUC manuals
-
On internal labels of the amplifier
-
In spare parts lists / wiring diagrams
✅ Simple Explanation
A06B-6117-C103 = internal configuration code of FANUC αiSV-20 servo amplifier (H103 model), not a separate hardware unit.
