Product Description:

The FC-321P4K0T5E20H2BGXXXXSXXXXANBXCXXXXDX is an AC variable frequency drive manufactured by Danfoss for the VLT EZ FC 321 Automation Drives series. This model serves as the speed-control element between a three-phase mains supply and an induction motor, allowing automation controllers to adjust pump, fan, or conveyor speed without mechanical throttling. By combining the series’ streamlined parameter set with chassis-mounted components, the drive supports rapid installation and dependable torque regulation inside standard control cabinets.

The inverter delivers a continuous output of 4.0 kW, equal to 5.5 HP, so it fits midrange machinery that requires moderate shaft power. It accepts a three-phase 380–500 VAC supply, covering typical 400 V and 480 V industrial power systems. The IP20 chassis enclosure permits cabinet mounting where basic protection against accidental finger contact is required. An integrated RFI Class A2 (C3) filter attenuates conducted electrical interference on industrial power lines. Because the printed circuit boards are not conformally coated, the unit should be installed in a clean, dry cabinet that protects the electronics from moisture and airborne contaminants.

Field connectivity is provided by the optional EtherNet/IP MCA 121 interface, allowing status words and setpoints to travel over a standard Ethernet network. Local adjustments are performed through a graphical local control panel that displays real-time current, frequency, operating information, and alarm codes. For dynamic deceleration or emergency energy dissipation, an internal brake chopper connects the DC bus to an external resistor. Power and control conductors enter through standard cable entries, eliminating the need for special gland plates and reducing the amount of panel preparation required during installation. The accessible display and network connection support both local operation and centralized control without requiring separate interfaces for routine drive monitoring.
