Product Description:

The FC-321P7K5T2P66H2BGXXSXSXXXXANBXCXXXXDX variable-frequency drive is manufactured by Danfoss for the VLT EZ FC 321 Automation Drives series. It converts fixed-frequency mains power into a modulated output so that induction motor speed and torque can be adjusted to match process demand. The unit mounts as a stand-alone package close to the load, supplying regulated motion for conveyors, pumps, and other industrial axes that benefit from energy savings and accurate velocity control. This arrangement reduces the distance between the drive and motor while providing direct access to the enclosure for routine operation. Its variable-speed output also allows connected equipment to avoid running continuously at full speed when the process requires less flow or movement.

Electrical performance centers on a power rating of 7.5 kW, which corresponds to 10 HP of shaft capacity under nominal conditions. The input section accepts a three-phase 200–240 VAC supply, fitting low-voltage distribution panels common in packaging and material-handling lines. An enclosure rated at IP66 / NEMA 4X protects the internal circuitry from dust, high-pressure washdown, and corrosion. Conducted emissions are limited by an integrated RFI Class A2 (C3) filter, helping prevent electromagnetic interference from disrupting nearby sensors and control equipment. Local setup is performed through the Graphical Local Control Panel, which displays speed, current, and fault codes while permitting parameter changes without a separate computer. The panel also provides direct access to operating status and drive controls at the installation location.

Real-time network traffic is handled by the A-slot interface, which uses EtherNet/IP MCA 121 to support explicit and implicit messaging with compatible PLCs. Dynamic braking energy is routed through an internal brake chopper, helping maintain controlled stopping times while protecting the DC bus from excessive voltage. Adaptation A provides smooth imperial cable entries that accept standard trade-size conduit glands. These entries simplify conduit alignment and support sealed cable routing into the enclosure. The network connection supports the exchange of commands, operating data, and diagnostic information between the drive and the control system. Braking control is especially useful for applications in which driven equipment must decelerate quickly or stop repeatedly during normal production cycles.
