Product Description:
The FC-321P4K0T5E20H2BGXXXXSXXXXAXBXCXXXXDX is a variable frequency drive manufactured by Danfoss for the VLT EZ FC 321 Automation Drives series. The device converts fixed-frequency mains power into controlled output voltage and frequency so three-phase induction motors can follow precise speed references. By regulating motor speed instead of relying on mechanical dampers, it supports energy-efficient operation of conveyors, pumps, and fan arrays in industrial plants. The chassis-mount form factor allows installation inside standard control cabinets alongside contactors, circuit breakers, and PLC hardware.
Rated for 4.0 kW of continuous output, the unit corresponds to 5.5 HP. It accepts a three-phase input range of 380–500 VAC, eliminating the need for step-up or step-down transformers in most factories. The enclosure has an IP20 protection rating, meaning live parts are protected against finger contact, but the drive requires installation in a dry cabinet. An integrated RFI Class A2 (C3) filter attenuates conducted noise, helping the installation meet industrial electromagnetic compatibility requirements. When the motor must stop quickly, the internal brake chopper diverts excess DC-bus energy to an external resistor, preventing overvoltage trips during high-inertia deceleration.
Operator access is provided through the graphical local control panel, which displays parameters, fault codes, and process values without requiring external software. Text strings are stored in the Standard Language Pack, allowing users to select commonly used languages from the keypad. Wiring is routed through the series’ standard cable-entry arrangement, helping organize power, motor, and control conductors within the cabinet. The electronics use uncoated printed circuit boards, so the drive should be mounted away from corrosive vapors and condensing moisture. All optional slots are left empty, keeping the AutomationDrive EZ configuration simple for original equipment manufacturer panel designs.
