Model NumberA06B-6089-H711

BrandFANUC

Product CategoryServo system accessory, external regenerative discharge resistor unit

Alternative NamesRegenerative resistor, braking resistor, power dissipation resistor

Basic InformationManufactured by FANUC and made in Japan. It is built with metal cabinet structure, equipped with built-in cooling fan and terminal block connection. The unit weighs around 8 to 10 kilograms. Adopting forced air cooling design, it provides higher power dissipation capacity.

Function & PositioningIt absorbs and consumes regenerative power generated while servo motors decelerate and brake. It effectively prevents DC bus overvoltage failures. This high-power external auxiliary component matches heavy-duty Alpha SVU servo amplifiers, applicable to harsh working conditions with large inertia load and frequent high-speed braking.

Core Performance ParametersContinuous rated power reaches 800 watts. Working DC bus voltage ranges from 283 volts direct current to 339 volts direct current. Forced air cooling mode ensures stable heat dissipation. Thermal overload protection is integrated, and protection signals can be connected to machine alarm and emergency stop circuits.

Compatible AccessoriesCompatible with A06B-6089-H106 single-axis servo amplifier. It fits Alpha SVU1-130 and SVUC1-130 high-power servo drive series. It also works with PSMR-5.5 and iPSR5.5 power supply modules.

Application FieldsSuitable for large CNC machining centers, heavy gantry machine tools and heavy-duty lathes. Widely used on industrial robot extended axes and heavy-load automatic production lines. Ideal for mechanical equipment with frequent start-stop movement and high inertia servo control demands.
