Product Description:

The FC-321P1K5T5E20H2BGXXXXSXXXXAXBXCXXXXDX is an AC variable frequency drive manufactured by Danfoss for the VLT EZ FC 321 Automation Drives series. It belongs to the VLT AutomationDrive EZ product group and converts fixed mains power into a variable-frequency output that allows control systems to adjust motor speed, torque, and process throughput. Adjustable motor operation can reduce energy consumption and mechanical stress in pumps, fans, conveyors, and other material-handling equipment. The drive is suitable for industrial and commercial installations that require controlled acceleration, stable speed regulation, and efficient operation under changing loads.

The drive delivers a continuous output of 1.5 kW, with an equivalent motor rating of 2.0 HP, making it suitable for smaller motor installations that do not require a large inverter. It accepts a three-phase 380–500 VAC supply and can connect directly to common industrial power systems within that voltage range. The unit has IP20 chassis protection, which protects against accidental finger contact with internal components but requires installation inside a clean enclosure. Conducted emissions are limited by the factory-installed RFI Class A2 (C3) filter, which is intended for general industrial environments rather than residential locations. Proper enclosure spacing should permit heat to escape while preventing dust, conductive debris, and accidental contact from reaching the drive. These installation conditions also help maintain dependable operation when the converter controls motors with frequently changing speed or torque demands.

Dynamic motor stopping is supported by an integrated brake chopper, which allows an external braking resistor to dissipate regenerated energy during rapid deceleration. Local setup and operation are handled through the graphical local control panel, which presents drive parameters and operating information through a multilingual interface. The panel uses a standard language pack to make menus and status messages available in commonly supported languages. Power and signal conductors pass through standard cable entries, providing an organized route for field wiring into the chassis. The printed circuit boards are not coated, so the drive should be installed away from corrosive gases, excessive humidity, and contamination that could damage exposed conductive surfaces. Appropriate cable separation can also reduce interference between motor power wiring and low-voltage control signals during operation.
