Fanuc PCB Board Brand New A16B-2201-0440 A16B22010440 A16B-22O1-O44O

A16B-2201-0440 | FANUC AC Spindle Control PCB — A06B-6064-H3xx / Serial Fibre-Optic Interface / 6kW–30kW Spindle Range

A06B-6064-H3xx — The Last Generation of Yellow-Frame AC Spindle Drives

The A16B-2201-0440 is fitted across the entire A06B-6064-H3xx series of FANUC AC spindle servo units. These drives represent the last generation of FANUC's open yellow ABS plastic framed spindle amplifiers — identifiable by their distinctive open-frame yellow enclosure design before FANUC transitioned to fully enclosed drive hardware.

The "H3xx" designation within the A06B-6064 family identifies the mid-to-large power range models — covering spindle motor outputs from 6kW through to 30kW. This range serves the broad majority of CNC machining centre and turning centre spindle power requirements.

Key Specifications

6kW to 30kW — One Control Card Across the Full Power Range

The A16B-2201-0440 serves the complete A06B-6064-H3xx power range — from 6kW entry-level machining centre spindles to 30kW heavy-duty cutting spindles. The same serial control card architecture spans this fivefold power range, with the power section of each drive model scaled to its rated output while the control card and communication interface remain consistent.

This single-card commonality simplifies spares management: one A16B-2201-0440 card covers all H3xx spindle drives across the range, regardless of the spindle motor's rated power.

Application Scenarios

A06B-6064-H3xx spindle alarm — control card fault: A FANUC machining centre develops spindle alarms. After verifying the spindle motor and fibre-optic link, the A16B-2201-0440 control card is identified. Replacement restores serial spindle communication and spindle drive function.

Serial spindle drive maintenance: A CNC turning centre's A06B-6064-H3xx spindle drive undergoes control card replacement. The A16B-2201-0440 is the correct replacement for all H3xx models across the 6kW–30kW range.

FAQ

Q1: Which specific A06B-6064-H3xx drive models use A16B-2201-0440?

A16B-2201-0440 is fitted across the entire A06B-6064-H3xx series — all H3xx model numbers within the A06B-6064 family of yellow-frame serial spindle drives. The "H3xx" designation covers multiple specific models (H301, H302, H303, etc.) all sharing the same serial spindle control card. Confirm from the drive's front nameplate that the drive model reads A06B-6064-H3xx.

Q2: What fibre-optic cable connects the A16B-2201-0440 to the CNC, and how do I diagnose fibre-optic communication faults?

The fibre-optic spindle link uses FANUC's standard plastic fibre-optic cable with defined transmit and receive connectors on the A16B-2201-0440 card. A communication fault shows as a spindle serial alarm (typically alarm SP9730 or similar serial link error) on the CNC display. Diagnose by: checking for physical cable damage or contamination at the fibre connector ends, verifying the CNC's spindle serial interface card is functioning, and checking that the drive is powered and in the correct operational state before the link can be established.

Q3: Does replacing A16B-2201-0440 require spindle parameter re-entry?

Spindle parameters reside in the CNC's parameter memory — not in the spindle drive's control card. After fitting the replacement A16B-2201-0440, the CNC re-downloads spindle parameters to the drive via the serial link during power-on initialisation. Verify correct spindle speed response across the range before returning to production.

Q4: What safety precautions apply before accessing the A16B-2201-0440 inside the spindle drive?

Switch off and lock out the mains supply to the spindle drive. The A06B-6064 series DC bus retains charge after mains power removal — verify the DC bus is below 30V using a calibrated voltmeter before accessing internal boards. Handle A16B-2201-0440 with an anti-static wrist strap on an ESD-safe surface.

Q5: Are the IGBT transistor modules on the same PCB as the A16B-2201-0440 control card?

The spindle control card (A16B-2201-0440) and the IGBT power transistor modules are separate components within the A06B-6064-H3xx drive. The control card handles the serial communication and drive control algorithms. The IGBT transistor modules form the power stage. Both are separately replaceable — if an IGBT failure has caused collateral damage to the control card, both components should be inspected when the drive is opened.
