Faunc Power 12V Amplifier PCB CNC Circuit Board A16B-2202-0750
A16B-2202-0750 | FANUC A16B-2202 Series PCB — 075x Range / Series 21 and 210 CNC Control Board Spare
A16B-2202 — The Series 21 and 210 CNC Board Family
The A16B-2202 series is confirmed as the PCB family serving FANUC Series 21 and Series 210 CNC control platforms. Within this series, confirmed boards include:
| Board | Description |
|---|---|
| A16B-2202-0750 | 075x range — this product |
| A16B-2202-0900 | 21/210 B Control Main PCB (090x range) |
| A16B-2202-0980 | 21/210 Control I/O PCB D1 (098x range) |
The A16B-2202-0750 at the 075x position predates both the 0900 main PCB and the 0980 I/O board in the part number sequence — placed in the lower-to-mid range of the confirmed A16B-2202 board family.

FANUC Series 21 and 210 — The CNC Platform
The FANUC Series 21 is a high-performance CNC platform for machine tool control — covering turning (21-T), machining centre (21-M), and combined operations. The Series 210 is the high-axis-count variant serving machines requiring coordinated multi-axis motion beyond the standard Series 21 capability.
The Series 21 and 210 CNC platforms use a common PCB architecture centred on the A16B-2202 board family — multiple PCBs within this series handle the main CPU, I/O, servo control interface, and communication functions within the CNC control unit.
Application Scenarios
CNC control board fault: A FANUC Series 21 or 210 CNC develops a fault traceable to a board at the A16B-2202-0750 position. The board is identified from its part number label. Replacement restores the specific function served by this board.
Planned maintenance spare: A production facility maintaining FANUC Series 21 or 210 CNC equipment stocks A16B-2202-0750 for the specific machine in which it is installed.
FAQ
Q1: How do I confirm A16B-2202-0750 is the correct board for my FANUC CNC?
Read the part number from the installed board's label inside the CNC control unit. If it reads A16B-2202-0750, this is the confirmed replacement. Cross-reference with the applicable FANUC Series 21 or 210 maintenance manual's board layout diagram and spare parts list to confirm the board's slot position.
Q2: What FANUC CNC systems use A16B-2202 series boards?
The A16B-2202 series serves FANUC Series 21 and Series 210 CNC platforms — confirmed from adjacent boards A16B-2202-0900 (21/210-B Control Main PCB) and A16B-2202-0980 (21/210 Control I/O PCB D1). The specific machine tool model using A16B-2202-0750 is confirmed from the CNC control unit's system configuration screen.
Q3: Does replacing A16B-2202-0750 require CNC data backup?
This depends on the board's specific function. If it is a control board with processor or memory functions, full parameter and programme backup is required before replacement. If it is an I/O or interface board, stored CNC data is typically unaffected. Confirm from the FANUC Series 21/210 maintenance manual for the specific board function at the 075x position.
Q4: What ESD precautions apply to A16B-2202-0750?
Handle with a grounded anti-static wrist strap on an ESD-safe surface. Store in anti-static packaging. Power the CNC completely down before accessing the control unit. FANUC A16B boards contain precision CMOS logic devices sensitive to electrostatic discharge.
