FR-A520-2.2K

What type of equipment is this used for?

This is a transistorised AC inverter drive used to control the speed and torque of compatible AC motors by varying the output frequency and voltage.

What motor power rating is it designed for?

It is rated for a 2.2 kW motor application (when correctly matched to the motor and duty).

What input supply voltage is required?

It is designed for the 200–240 V AC supply class. Always confirm the exact input wiring and permissible supply configuration from the drive nameplate before installation.

What is the rated output current?

The rated current is 16 A (nameplate rating). Ensure the connected motor full-load current and required overload capability are suitable.

What output frequency range does it provide?

The output frequency range is 0.2 to 400 Hz, allowing both low-speed operation and higher-speed applications where the motor and mechanics permit.

Can it run a motor above base speed?

Yes, the drive can be set above typical base frequency (up to 400 Hz). In practice, overspeed is limited by the motor design, cooling, bearings, and the driven machine, so the whole system must be evaluated.

Is it suitable for variable-torque loads such as fans and pumps?

It is commonly used on variable-torque applications such as fans and pumps, as well as constant-torque duties (for example conveyors), provided the drive and motor are correctly sized for the load profile.

How is the drive typically controlled (local vs external control)?

It can be operated using a local operator/control panel interface and/or via external control wiring, depending on how the terminals and parameters are configured.

Is an operator panel required to set parameters?

An operator/control panel is typically used for commissioning, monitoring, and parameter changes. The FR-DU04 control panel is commonly associated with this series; confirm suitability for your exact unit and application.

Can it be used as a replacement within the same inverter family?

It is part of Mitsubishi’s A500 series (A520, 200–240 V class). It is often used as a like-for-like replacement within the same family and power/current class, but I/O requirements and parameter settings should be checked before swapping.

Does it support dynamic braking?

Braking capability depends on the braking method selected and any required braking components. If your application uses rapid deceleration or high-inertia loads, confirm the braking arrangement needed for your setup.

What should be checked before selecting it for an application?

Confirm the mains supply class (200–240 V AC), motor power and full-load current versus the 16 A rating, required speed range (0.2–400 Hz), duty/overload needs, control interface requirements, and installation constraints such as enclosure space and cooling.

What information helps identify the correct configuration for a replacement?

Key details include the existing drive’s power/current rating, supply voltage class, control wiring (start/stop, speed reference, interlocks), any braking arrangement, and any special parameter settings. If you provide the original drive nameplate details and your motor current, it is easier to confirm whether FR-A520-2.2K is an appropriate match.
