Product Description:

Danfoss supplies the FC-321P22KT5P66H2BGXXSXSXXXXANBXCXXXXDX as part of the VLT EZ FC 321 Automation Drives series. This variable-frequency drive is intended for regulating three-phase induction motors used in conveyors, pumps, and general machinery across automated plants. By modulating output frequency, it helps maintain motor speed when load conditions change and allows smoother response during startup or braking. That makes it practical for equipment that must match motor speed to changing process demand rather than run at a fixed line frequency.

The drive is rated at 22 kW, equal to 30 HP, so it can run medium-sized industrial motors without requiring an oversized platform. It accepts a 380-500 VAC three-phase mains supply, and the backplate has an IP66 / NEMA 4X rating, allowing wash-down mounting outside a cabinet where dust or water spray may be present. A built-in brake chopper dissipates regenerated energy during rapid stops, which helps the drive handle deceleration events more cleanly. The printed circuit boards are uncoated, so the enclosure should remain sealed against moisture and contaminants during operation. No mains, B, C0, C1, or D options are installed, which keeps the wiring layout straightforward and avoids extra internal add-on sections.

System integration is handled through the A Option slot populated with EtherNet/IP MCA 121, giving cyclic data exchange to PLCs without external gateways. This communication path helps the drive exchange control words and status data as part of a larger automation system. Operators configure parameters on the Graphical Local Control Panel, and multilingual menus support routine setup, status review, and day-to-day adjustments. Adaptation A uses smooth imperial cable entries, while no additional mechanical adaptation is assigned for Adaptation B. The unit uses an uncoated PCB construction, so it should be kept within the protection provided by the sealed enclosure during use.
