Product Description:

The FC-301P5K5T2134L2970 is an AC variable-frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. It converts fixed-frequency mains power into a controlled output that allows PLCs to regulate induction motor speed and torque in material-handling equipment, pump skids, and fan arrays. By modulating the output waveform, the unit increases process flexibility while reducing mechanical stress on connected machines.

The power section accepts an input of 200–240 VAC from a three-phase power supply. Under these conditions, it can provide a continuous motor output of 5.5 kW, which is equivalent to 7.5 HP. The carrier frequency is adjustable up to 32 kHz, allowing users to balance acoustic noise against switching losses. The inverter can command the motor at a maximum electrical frequency of 590 Hz. Analog feedback to external controllers is produced with 12-bit resolution, providing detailed signal representation for process control. The sourcing terminals can supply up to 40 mA for transducer excitation, allowing compatible field devices to receive power directly from the drive.

Motor cabling may use conductors up to 10 mm² and may extend 50 m when shielded or 75 m when unshielded without exceeding reflected-wave limits. The flux optimization function supports magnetizing frequencies up to 300 Hz, improving efficiency at elevated motor speeds. Line-side performance includes a displacement power factor of >0.98, while the true power factor is at least 0.9 under nominal load. Short-circuit protection provides a withstand capacity of 100 kA RMS, helping protect the power section during severe electrical faults. The drive supports two controlled power-ups per minute to limit repeated charging stress on internal components. It can also continue operating with a mains phase imbalance of up to 3%, which supports stable motor control when incoming phase voltages are not evenly balanced.
