Product Description:
The FC-301P22KT4131X7316 variable-frequency drive is manufactured by Danfoss for the VLT FC 301 Automation Drives series. Inside an automation cell, it converts fixed three-phase mains power into a regulated electrical output. This output lets controllers vary induction motor speed and torque to match real-time load demands in production machinery.
Rated output power reaches 22 kW, allowing the inverter to support midrange production machinery. It accepts a three-phase supply of 380–480 VAC and produces motor frequencies up to 590 Hz; in flux-vector mode, the upper limit is 300 Hz. During rapid deceleration, a brake chopper activates when the DC link reaches 778 V DC, diverting regenerated energy to an external resistor. An 820 V DC alarm supplements this protection by signaling an excessive DC-link voltage. Starting torque can rise to 160% of the rated load for 60 seconds, supporting machinery that requires additional force during acceleration. The control loop provides a torque rise time of 1 ms under flux control or 10 ms when the VVC+ algorithm is selected. The unit should be energized no more than once per minute to limit inrush stress and component heating. A maximum phase imbalance of 3% is tolerated without derating.
The drive delivers 30 HP for systems that use U.S. customary power ratings. Full output is available at elevations up to 1000 m and at an ambient temperature of 45 °C when cabinet ventilation is adequate. The true power factor remains at 0.9 or higher, which limits reactive current and helps reduce loading on upstream transformers. Shielded motor cables may extend up to 50 m, while unshielded motor cables may extend up to 75 m, providing flexibility when arranging motors and control cabinets across a machine. Installation also permits a single unshielded cable run when applicable electromagnetic compatibility limits are satisfied. Adequate cable separation and grounding help maintain stable motor operation over the permitted cable lengths.
