Product Description:
The FC-301P5K5T4131X7281 is an AC variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. The unit regulates the speed and torque of induction motors used in conveyors, pumps, processing equipment, and other automated machinery. It converts fixed mains power into a modulated output that allows the connected controller to adjust motor speed according to changing load demands. This operation can reduce unnecessary energy use while providing controlled acceleration, deceleration, and steady-state rotation. The drive also supports coordinated machine operation by responding to commands from external control systems and returning status information through its signal terminals.
The inverter delivers a continuous mechanical output of 5.5 kW, equivalent to 7.5 HP, and accepts line voltages from 380–480 VAC through a three-phase power supply. It supports line frequencies of 50 or 60 Hz with a tolerance of ±5% and accepts voltage deviations of ±10% without derating. The output frequency is adjustable up to 590 Hz for motors intended to operate at elevated speeds. The drive may be energized no more than twice per minute to limit thermal cycling within the DC-link components. Its relay terminals can source up to 40 mA, while two digital outputs communicate operating status or fault conditions to external control equipment.
The signal interface includes two analog inputs with 10-bit resolution and one analog output with 12-bit resolution. These channels support proportional command and feedback signals for process controllers, sensors, and other automation devices. Flux-mode operation is limited to 300 Hz to maintain vector control and reduce motor heating at elevated speeds. For electromagnetic compatibility, the recommended maximum length for a shielded motor cable is 50 m. An unshielded motor cable may extend to 75 m when the installation does not require the same shielding arrangement. Two digital outputs provide additional status signaling, and the available analog channels allow the drive to exchange speed references and process values without separate signal-conversion hardware.
