Description
🔧 FANUC A16B-2203-0696 – Wiring Board (3-Axis Servo Amplifier)
A16B-2203-0696 is a FANUC internal wiring PCB (printed circuit board) used specifically inside Alpha i (αi) 3-axis servo amplifier modules.
🧠 What It Is
👉 A16B-2203-0696 = Wiring Board / Interconnection PCB
- Type: Internal wiring / interconnection PCB
- Series: A16B-2203
- Used In: 3-axis (SVM3) servo amplifiers
-
Typical Modules:
- A06B-6114-H301 / C301
- A06B-6117-H301 / C301
⚙️ Exact Function
This board is specifically identified as a “wiring board” in FANUC documentation.
🔌 What it does:
- Distributes power and signals inside the servo amplifier
- Connects:
- Control PCB (A20B series)
- Power stage (IGBT/inverter section)
- Feedback and motor outputs
- Acts as a backplane / interconnection layer for internal modules
👉 It does not process logic — it mainly routes electrical connections between boards.
🏭 Where It Is Used
From FANUC system configuration:
- Used in SVM3-4/4/4i (3-axis low-power amplifiers)
- Found inside:
- A06B-6114-H301 / C301
- A06B-6117-H301 / C301
So whenever you have a 3-axis (4/4/4) amplifier, this board is typically inside.
🔍 Key Role in System
Inside the amplifier stack:
- 🧠 Control board → (A20B-2101 / A20B-2100 series)
- 🔌 Wiring board → (A16B-2203-0696) ← YOU ARE HERE
- ⚡ Power module → drives motors
👉 This board is the “connection backbone” between all sections.
🧠 Simple Explanation
👉 A16B-2203-0696 is an internal wiring board inside a FANUC 3-axis servo amplifier that distributes power and signals between the control board and power circuits.
