Fanuc ai Servo Amplifier Power PCB 400VAC-input A20B-1008-0099

📦 FANUC A20B‑1008‑0099 — Description

Part Number: A20B‑1008‑0099
Description: FANUC PCB / Printed Circuit Board — an internal electronic board used in FANUC CNC systems or drive electronics.
👉 This part belongs to the A20B‑1008 series, which includes a wide range of PCBs (printed circuit boards) used for various control, interface, logic, and drive functions in FANUC industrial automation equipment.

🔧 What It Is

• Type: Internal control/driver PCB / printed circuit board
• Series: A20B‑1008 — FANUC PCB family
• Usage: Installed inside FANUC CNC controllers, servo amplifiers, spindle drives, or related electronic modules
• Function:
  • Provides electronics for specific subsystem control (such as communication between boards, signal conditioning, or interface to power/logic sections)
  • Works alongside other FANUC boards (CPU, I/O, driver PCBs) in the machine’s control or drive cabinet

Boards in the A20B‑1008 range are not standalone products — they are meant to be part of a larger FANUC control/drive system, often handling a specific role inside that system’s electronics.

📌 Typical Characteristics & Uses

• Found in FANUC CNC controller electronics or drive modules (e.g., servo or spindle drive PCBs)
• May perform signal routing, logic processing, or interface functions between controller logic and power/drive stages
• Often sold as new, used, or refurbished replacement PCBs for repairing FANUC controllers or drives
• Many related A20B‑1008 boards include:
  • Connector PCBs
  • Robot PCBs
  • Brake Unit PCBs
  • Phase Detector PCBs
  • … all part of the same A20B‑1008 family

🧠 In Summary

👉 FANUC A20B‑1008‑0099 is a printed circuit board (PCB) in the A20B‑1008 series.
👉 It is used internally in FANUC CNC control or drive electronics for logic, interface, or subsystem functions — not as an external module.
👉 It pairs with other FANUC boards to enable proper operation of CNC controllers or servo/spindle drive modules.
