Product Description:
The FC-301P4K0T4131B8986 is an AC variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. It converts fixed-frequency three-phase mains power into a regulated output that allows controllers to match motor speed and torque to real-time load demands in conveyors, pumps, or fan assemblies. Within the VLT AutomationDrive FC product group, the unit acts as a compact controller that supports closed-loop flux and VVC+ control algorithms for general industrial automation.
The embedded analog output has a 12-bit resolution, allowing proportional feedback, such as a speed reference, to be sent to external indicators. The drive has two digital outputs that can transmit status flags to PLC inputs. For sensor power, the 24 V terminal can supply up to 200 mA, while each digital output is limited to 40 mA to protect the onboard transistors. The input supply must remain between 380 and 480 VAC, and the inverter provides 4.0 kW of continuous motor power on a three-phase network. One changeover relay provides a galvanically isolated fault or ready contact. The PWM stage has a maximum switching frequency of 32 kHz, and the drive can increase torque in flux mode within 1 ms, supporting rapid corrections during process disturbances.
For applications that require an extended speed range, the controller can generate a fundamental output frequency of up to 590 Hz, although magnetic flux regulation is limited to 300 Hz. Shielded motor cable runs may be up to 50 m long, while unshielded runs may reach 75 m before reflected-wave voltages require external filters. Short-term overload capacity reaches 160% for one minute in every ten minutes. Variable-torque loads may draw 110% for 0.5 seconds without tripping, while the starting torque capacity reaches 160% for 60 seconds. The 301 identifier indicates shared hardware with other FC-301 variants. VVC+ mode provides a 10 ms torque rise time to smooth acceleration in light-duty centrifugal machinery.
