Product Description:

The FC-301PK75T4Z20H3TGXXXXSXXXXALBXCXXXXDX is an AC variable-frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. It converts fixed-frequency line power into a pulse-width-modulated output, allowing induction motors to follow precise speed commands from PLCs or stand-alone controllers. By adjusting output voltage and frequency together, the drive supports efficient motor operation across changing process demands. It is suitable for pumps, fans, and small conveyor modules used in automated production lines. Closed-loop control functions help maintain stable acceleration, deceleration, and speed regulation when connected loads change during operation.

The inverter accepts a 380–480 VAC supply with three-phase power, matching common low-voltage industrial distribution systems. Its motor output is rated at 0.75 kW, which corresponds to a mechanical shaft capability of 1.0 HP. The IP20 enclosure helps prevent accidental contact with live internal parts when the drive is installed inside a suitable control panel. An internal heat sink dissipates operating heat and supports continuous service under normal cabinet conditions. The printed circuit boards do not have a conformal coating, so the unit should be installed in a clean, dry enclosure protected from condensation and corrosive contaminants. An internal DC-link choke smooths current and helps reduce electrical stress within the power circuit.

The A-slot contains a PROFINET MCA 120 interface for exchanging cyclic setpoints, operating data, and diagnostic information over Industrial Ethernet. A front-mounted Graphical Local Control Panel provides access to parameters, status information, and trend data without requiring an external programming device. The integrated Safe Stop function disables torque-producing output when the safety input is activated. An integrated EMC filter reduces conducted electromagnetic emissions, which can eliminate the need for external radio-frequency interference accessories in suitable installations. Standard cable entries simplify routing through the gland plate and help keep power, motor, and control wiring organized. The standard language pack supports local menu navigation, while the internal control functions provide stable speed ramps and motor slip compensation.
