Bonfiglioli ACT401-05FA Frequency Inverter

Buy online your Bonfiglioli ACT401-05FA Frequency Inverter from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

The Bonfiglioli ACT401-05FA is a compact frequency inverter designed for precise speed and torque control of three-phase AC motors in CNC and industrial automation systems. Commonly used for chip conveyors, coolant pumps, hydraulic pumps and ventilation fans, it provides reliable motor regulation and smooth acceleration/deceleration in industrial control cabinets.

This ACT401 series drive supports standard control terminals, analog speed reference inputs and fault signaling integration with PLC or relay-based systems. Rated at 0.55 kW with 1.8 A output current, it operates on a 380–480 V three-phase power supply and features an IP20 cabinet-mounted enclosure.

Widely used as a replacement or spare part, the ACT401-05FA helps maintenance teams quickly restore machine operation while keeping existing wiring and control logic unchanged. Suitable for retrofit projects and legacy machine support, it is commonly supplied as a tested or refurbished unit with fast dispatch and worldwide shipping options.

Frequently asked questions about ACT401-05FA:

What motor types does this inverter control
It is designed for three-phase asynchronous motors used on machine-tool auxiliaries and general industrial equipment. Match the unit’s rating to the motor’s voltage, current and power as specified by the manufacturer.

Can it replace another Bonfiglioli inverter of similar rating
Yes when voltage, current class, control method and mounting space are equivalent. Verify terminal assignments and replicate key parameters such as motor data, acceleration and deceleration times to achieve a drop-in replacement.

Which control signals are commonly used for integration
Typical wiring uses digital inputs for run and direction, an analog input for speed reference when needed and a relay output for status or fault indication. Confirm the specific terminal layout in the technical manual before commissioning.

What should maintenance teams prepare before a field replacement
Record the old drive’s parameters if accessible, confirm motor nameplate values and check cabinet wiring labels. Having this information ready allows faster setup and reduces machine downtime during the changeover.

What is the typical lead time for shipment
Dispatch is generally organized within three days depending on inventory and order timing. Contact our team for current availability or to discuss surplus stock, refurbishment or exchange service options.
