A06B-6134-K002 US80D24-K 80mm 240V AC 11W 10W Ball Bearing Cooling Fan Assembly

This complete 240V AC external heat-sink cooling fan assembly is designed for compatible βi-series servo amplifier configurations that specify A06B-6134-K002. The assembly includes the axial cooling fan, metal mounting plate, protective wire guard, two-wire power lead, two-position screw terminal block, and installed mounting hardware.

The installed fan model is US80D24-K, rated for 240V AC operation at 50/60Hz. This is the complete external radiator fan unit—not an internal circulation fan or an unmounted replacement fan motor.

Documented fan-level service reference:

A90L-0001-0445#B
A90L00010445B

A90L-0001-0445#B is the fan-motor service reference documented for the A06B-6134-K002 external radiator fan unit in later service literature. A replacement supplied under the fan-level number may contain only the fan motor and may require reuse of the original guard, mounting plate, wiring, terminal block, or hardware.

Additional Fan Model Cross-Reference

UTM858CG is also associated with replacement-market A06B-6134-K002 assemblies. This alternate fan is commonly identified as an 80mm × 80mm × 38mm 240V AC fan with a 13/11W rating.

Because the UTM858CG rating differs from the installed US80D24-K rating, the two loose fan motors should not be treated as automatically interchangeable. A substitute must match the following:

• 240V AC operating voltage
• 50/60Hz frequency
• Physical fan dimensions and mounting-hole pattern
• Airflow direction
• Rotation direction
• Lead length and termination
• Guard and mounting-plate clearance
• Required airflow and power consumption

A complete A06B-6134-K002 assembly is the preferred replacement when the original bracket, guard, terminal block, or wiring is damaged or missing.

⚠️ Critical Fan Compatibility Notice

This is a 240V AC fan assembly. It must not be replaced with a visually similar 24V DC fan.

A06B-6134-K001, A06B-6134-K003, A06B-6134-K005, and A06B-6134-K006 identify different cooling assemblies or application configurations. They are not automatic substitutes for A06B-6134-K002.

The fan assembly must be selected according to the amplifier model, input-power configuration, connected motor, mounting arrangement, and original fan-unit number. Matching only the fan dimensions is not sufficient.

✅ Confirmed Compatibility

Compatibility applies to amplifier configurations that specifically require the A06B-6134-K002 external radiator fan unit.

✔️ SVM1-80i / βiSV80 — A06B-6130-H004: All documented 80A-class motor configurations
✔️ SVM1-20i / βiSV20 — A06B-6130-H002: Three-phase 200–240V configurations paired with an α4/5000is motor
✔️ SVM1-20i / βiSV20 — A06B-6130-H002: Three-phase 200–240V configurations paired with a β8/3000is motor
✔️ SVM1-80i I/O Link — A06B-6132-H004: Configurations using the external K002 heat-sink fan unit
✔️ SVM1-40HVi / βiSV40HV — A06B-6131-H003: All documented motor configurations
✔️ βiSV80-B — A06B-6160-H004: Configurations specifying the K002 radiator cooling fan assembly
✔️ βiSV40HV-B — A06B-6161-H003: Configurations specifying the K002 radiator cooling fan assembly
✔️ βiSV80-B I/O Link — A06B-6162-H004: Configurations originally equipped with the K002 external radiator fan unit

The SVM1-20i / βiSV20 does not use this fan assembly in every configuration. The K002 unit is specifically documented for the three-phase 200–240V combinations listed above. Other input-power and motor combinations may require A06B-6134-K003 or a different cooling arrangement.

⚙️ Fit Notes

• Confirm that the original assembly number is A06B-6134-K002 before ordering.
• The extended marking A06B-6134-K002-0B2A identifies a documented production configuration of the K002 assembly.
• Match the original fan voltage. This assembly requires 240V AC and must not be connected to a 24V DC fan circuit.
• High-voltage amplifier configurations may use a 400–480V main input while still requiring a separately supplied 240V fan circuit.
• Do not connect the fan directly across a 400–480V source.
• Confirm the screw-terminal location, wire routing, mounting-hole spacing, bracket orientation, and airflow direction.
• The airflow arrow and rotation arrow on the replacement fan should match the original installation.
• Reversing the mounting orientation can reduce heat-sink airflow even when the fan is operating.
• A fan-only replacement may require transfer of the original plate, guard, wires, terminal block, and mounting hardware.
• Do not assume that A90L-0001-0445#A, UT857CG, or another similar-looking 80mm fan is interchangeable with the documented A90L-0001-0445#B configuration.
• Do not substitute K001, K003, K005, or K006 assemblies solely because their part numbers or mounting arrangements appear similar.
• Disconnect and lock out input power before servicing the fan.
• Allow the amplifier DC link to discharge completely and verify that the charge indicator is off before touching the assembly or wiring.
