- Application: Internal board in servo amplifiers (α / αi series)
👉 This model (0812) is simply a variant/revision of the same power board series, not a completely different function.
⚙️ Main Function:
This board performs critical internal functions inside the servo amplifier:
- ⚡ Power distribution within the drive
- 🔄 Supports servo motor drive circuits
- 🔌 Handles internal electrical connections and signal routing
- 🔗 Interfaces between CNC controller and amplifier electronics
👉 In simple terms:
It is a power + control support board that helps the servo amplifier run CNC machine axes smoothly.
🧩 Where It Is Used:
- Installed inside FANUC α / αi servo amplifiers
- Common in:
- CNC machining centers
- CNC lathes
- Industrial automation systems
🔍 0812 vs Other Variants (0810 / 0811 / 0815):
- Same core function (power PCB)
- Differences are usually:
- Minor circuit updates
- Component revisions
- Compatibility with specific amplifier models
👉 Important:
Replacement between versions is not always plug-and-play — must verify with exact amplifier model.
