Product Description:
The FC-301PK75T4131X7305 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. In automated plants, it converts a fixed-frequency three-phase supply into a variable waveform that allows induction motors to track commanded speed and torque, maintaining process accuracy and limiting energy consumption. The unit is intended for compact conveyors, small pumps, and handling axes that require fine speed regulation without additional mechanical throttling. Its variable output allows connected equipment to operate at the speed required by the process rather than continuously running at full speed.
The drive has a rated output of 0.75 kW, which is equivalent to 1.0 HP at the motor shaft. The power section accepts a 380–480 VAC three-phase supply and can raise the synthesized output frequency to 590 Hz, while magnetic flux control is limited to 300 Hz to keep the motor within a safe excitation range. Short bursts of load are supported by the 160% for 1 minute in every 10 minutes overload class, allowing intermittent acceleration without causing protective trips. A displacement factor above 0.98 keeps the source current nearly in phase with the voltage, and the control terminals tolerate up to 28 V DC on logic inputs. No more than two power-ups per minute are permitted to protect the DC-link capacitors from thermal stress.
Machine interfaces include four digital inputs, two transistor outputs limited to 40 mA, and one analog channel that resolves feedback with 12-bit precision. Under load, the installation maintains a true power factor of at least 0.9, reducing demand on upstream switchgear. Motor cabling may extend to a maximum of 50 m with shielded cable or 75 m with unshielded cable, helping control rise-time losses at the selected carrier frequency. One analog output is also available for transmitting a monitored process value or drive status signal. The integrated control connections support communication with external automation equipment without requiring separate signal conversion hardware.
