FANUC A90L-0001-0598 is a 24VDC radiator cooling fan used in compatible FANUC βiSVSP-B integrated servo and spindle amplifier modules. It moves air across the amplifier heat sink to maintain a safe operating temperature.
A90L-0001-0598 is a base family number, so the suffix must be confirmed. A90L-0001-0598#A commonly corresponds to Sanyo Denki 9WF0924S2031, while A90L-0001-0598#B corresponds to 9WF0924S2041. Both are rated 24VDC and 0.5A, but their harness arrangements and amplifier applications are different.

βiSVSP-B Radiator Cooling Function
The A90L-0001-0598 draws cooling air through the heat-sink section of the amplifier. Worn bearings, reduced speed, blocked airflow or a failed rotation signal can contribute to fan alarms and overheating. Replace a noisy or seized fan promptly and clean the heat sink and air path during service.
#A and #B Compatibility
The #A version is documented for selected 180mm and 260mm βiSVSP-B models using fan units A06B-6320-C601 or A06B-6321-C601. The #B version is documented with A06B-6320-C602 on higher-capacity 260mm models. Verify whether the required supply is one fan motor or a complete paired-fan harness assembly.
Testing and Installation Notes
REACO CNC checks the full nameplate, frame, blades, bearings, wiring, connector, running current and rotation before shipment. Match the original airflow direction and cable routing. Qualified personnel must isolate power and wait for the amplifier DC bus to discharge before opening the unit.
