Product Description:

The FC-301P30KT2131L0691 is a variable frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. As a three-phase AC inverter, it modulates line power to regulate induction motor speed and torque in conveyors, pumps, and general machinery. The drive supports closed-loop control, allowing connected equipment to maintain accurate process speed as operating loads change. Its design is suitable for industrial automation systems that require controlled acceleration, responsive torque adjustment, and efficient operation.

The drive’s output section is rated for 30 kW of mechanical shaft power. It accepts a three-phase supply of 200 to 240 VAC and draws a continuous line current of 104 A. Under rated operating conditions, the inverter can provide an output current of 115 A. Its operating efficiency is 0.97, so only a small portion of the incoming energy is converted to heat. Power loss at rated load is limited to 1.143 kW, which reduces the amount of heat that must be removed from the panel. A flux-based torque response time of 1 ms supports rapid command changes and tight velocity control during acceleration or changes in mechanical load.

During dynamic duty cycles, the inverter can supply 150% of rated current for 1 minute every 10 minutes before derating is required. Its starting sequence provides 160% of nominal motor torque for 60 seconds, helping heavily loaded conveyors overcome initial inertia without placing unnecessary stress on the gearbox. Full-load operation is permitted at elevations up to 1000 m and at an ambient temperature of 45 °C. Derated operation is available at ambient temperatures up to 55 °C. Installation permits as much as 50 m of shielded motor cable or 75 m of unshielded motor cable, allowing the drive to control remotely mounted motors while limiting reactive losses. The drive should be powered up no more than once per minute to protect the DC-link capacitors from repeated charging current.
