Product Description:

The FC-280P5K5T4H2BNCXXXSXXXXAN belongs to the VLT FC 280 Midi Drives series manufactured by Danfoss. It is an AC variable frequency drive that converts fixed-frequency mains power into a variable-frequency output, allowing a controller to match motor speed to process demand in conveyors, pumps, and ventilation equipment. By electronically adjusting output frequency and voltage, the unit can reduce energy consumption when an application does not require the motor to operate continuously at full speed. Controlled acceleration also produces smoother startups and reduces mechanical stress on connected equipment. Built-in motor control functions help maintain stable operation without relying on mechanical throttles or a separate soft starter.

The drive provides 5.5 kW of continuous motor power, which corresponds to 7.5 HP. Its power stage connects directly to a three-phase 380–480 VAC supply, covering a common industrial voltage range without requiring an autotransformer. The unit has no brake chopper, so regenerative energy produced during deceleration must be managed through the application or separate braking equipment. Deceleration settings should account for the connected load’s inertia and the amount of energy returned to the DC bus. The housing has no integrated display, so parameter access requires a compatible plug-in keypad, PC-based tool, or communication interface. This arrangement allows the selected control method to match the machine’s existing automation system while keeping the front of the drive compact.

The drive uses uncoated control boards, making it suitable for installation in a clean, dry electrical cabinet that protects the electronics from conductive dust, moisture, and corrosive vapors. Adaptation A and Adaptation B use no adaptation settings, so the standard parameter structure remains available without application-specific macros or dedicated sensor functions. The numeric identifier 280 appears in the model designation and associates the unit with the FC 280 product line. Its product grouping is Midi Drive FC, placing it among compact drives intended for general motor-speed control. Compatible communication accessories can connect the drive to a higher-level controller for command exchange, operating status, and diagnostic data. The available access methods support centralized control when the drive is mounted inside an enclosure without direct operator access.
