FR-A520-2.2K

What does this inverter drive do in an industrial system?

It controls the speed of an AC motor by converting a fixed AC supply into a variable-frequency, variable-voltage output. This allows smoother starting, better process control, and adjustable running speed.

What motor power rating is this unit intended for?

It is rated for 2.2 kW applications, making it suitable for many small-to-medium motor-driven machines and auxiliaries.

What supply voltage range is it designed to run on?

It is designed for a 200 to 240 V AC supply range.

What is the output frequency range available?

The output frequency range is 0.2 to 400 Hz, which supports both low-speed operation and extended-speed applications where the motor and machine are suitable.

What is the rated current for this drive?

The unit is rated at 16 A.

What types of applications commonly use this drive size?

Typical uses include conveyors, small pumps, fans, mixers, and general-purpose machinery where variable speed control and controlled acceleration/deceleration are required.

Can it be used to reduce mechanical stress during start-up?

Yes. As a variable-speed drive, it can start motors more smoothly than across-the-line starting by ramping frequency and voltage, which can reduce shock loading on couplings, belts, and gearboxes when correctly set up.

Is it suitable for operating at very low speeds?

It can output down to 0.2 Hz. Real-world low-speed performance depends on the motor, load characteristics, and application demands (for example, required torque and cooling at low rpm).

Is it suitable for high-speed operation above standard mains frequency?

The drive can output up to 400 Hz. Whether high-speed operation is appropriate depends on motor capability, mechanical limits of the driven equipment, and the overall application design.

What should I check to confirm it matches my existing installation?

Confirm the supply voltage (200–240 V AC), motor power requirement (around 2.2 kW), current requirement (up to 16 A), and the required operating frequency range. Also verify mechanical fit and the existing wiring/terminal configuration used in your panel.

Can this drive be used for both speed control and process stability?

Yes. Variable-frequency control helps stabilise processes by allowing finer adjustment of motor speed, which can improve consistency in flow, throughput, or mixing rates compared with fixed-speed operation.

How should it be described on a bill of materials (BOM) for maintenance teams?

A clear BOM description would be: A500 Series transistorised inverter drive, 2.2 kW, 200–240 V AC, 16 A, 0.2–400 Hz (often referenced as FR-A520-2.2K).
