Product Description:

The FC-301PK37T4Z55H1XGCXOXSXXXXAXBXCXXX is a variable-frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series within the VLT AutomationDrive FC product group. The unit regulates the speed of small AC motors, allowing a PLC to match motor torque and velocity to changing process demands without relying on mechanical throttling. Its sensorless vector control supports accurate motor operation without requiring a dedicated shaft encoder. Predefined parameter sets for pumps, fans, and conveyors simplify initial setup in general industrial automation systems. The drive can manage controlled acceleration and deceleration in compact machinery where smooth speed changes help reduce stress on connected mechanical components.

The FC-301 variant accepts a line supply ranging from 380–480 VAC and uses three-phase power, permitting direct connection to common industrial power systems. Its inverter section delivers 0.37 kW of continuous shaft power, which corresponds to 0.50 HP for light-duty applications with modest torque requirements. An integrated RFI Class A1/B filter attenuates conducted electrical noise on the motor and line conductors, reducing interference with nearby control equipment. The control system supports automatic motor tuning during startup so operating parameters can be matched to the connected motor. Status information and operating values are available locally, allowing faults, references, and motor conditions to be viewed directly at the drive. The controlled output also supports gradual speed transitions that can limit abrupt loading on pumps, fans, and conveyor mechanisms.

The printed circuit boards have a protective coating that resists moisture and airborne contaminants inside the enclosure. Cables enter through the European metric gland plate supplied with the housing, providing an organized path for line, motor, and control wiring. Local interaction is provided through the detachable Graphical Local Control Panel, which gives users access to parameters, operating data, and diagnostic messages. A multilingual Standard language pack supports menu navigation and status viewing in multiple languages. The detachable panel can be removed when direct local access is unnecessary or repositioned when the drive is installed inside a control cabinet. The installed configuration contains no additional expansion modules or integrated brake chopper.
