Product Description:

The FC-301P7K5T2131H3659 is a variable frequency drive produced by Danfoss as part of the VLT FC 301 Automation Drives series. It converts a constant-frequency electrical supply into a variable-frequency output that regulates the speed of a connected induction motor. This control method supports conveyors, pumps, material-handling fans, and similar automated equipment that require stable speed under changing process conditions. Matching the output frequency to the required operating point can reduce unnecessary energy consumption and limit mechanical stress on driven components. The compact chassis and rail-mounting pattern allow the unit to fit into control panels without extensive changes to the existing enclosure layout.

The drive provides a continuous motor output of 7.5 kW (10 HP), making it suitable for medium-duty machinery that requires consistent torque during extended operating cycles. Its input section accepts a mains supply ranging from 200–240 VAC, which supports use on low-voltage industrial distribution networks. The unit operates with three-phase power, distributing the electrical load across three supply lines and supporting balanced motor operation. Internal control algorithms regulate pulse-width modulation to produce the commanded motor voltage and frequency. This switching control helps the motor respond accurately to speed commands while limiting avoidable torque fluctuations. Proper input protection, grounding, and motor-cable routing remain necessary when the drive is installed in a cabinet with other automation equipment.

An integrated EMC filter suppresses conducted radio-frequency interference generated by the inverter switching stage. This filter can reduce the need for separate interference-suppression components when the installation conditions and applicable requirements permit its use. The drive uses internal identifier 301 for its parameter structure, providing an organized control map for motor data, operating commands, and diagnostic values. Its standardized parameter arrangement supports consistent configuration across compatible control systems without changing the drive’s physical I/O arrangement. The available control functions allow the output frequency to follow process commands while maintaining stable operation during acceleration, steady-speed running, and deceleration. Cabinet airflow must remain unobstructed so heat from the power electronics can leave the chassis during continuous service.
