Product Description:
The FC-301P1K5T4134L2716 is a variable frequency drive produced by Danfoss as part of the VLT FC 301 Automation Drives series. The unit converts fixed-frequency three-phase mains power into a regulated output that lets controllers modulate induction motor speed for conveyors, pumps, and material-handling systems. Its control algorithm uses the VVC+ vector principle, so torque can be maintained at low speeds without external feedback. Designed for cabinet mounting, the drive supports industrial automation tasks where compact size, rapid startups, and integrated safety functions are important.
The drive accepts three-phase input power from 380 to 480 VAC. Within this range, the electronics deliver a continuous output of 1.5 kW, equivalent to 2.0 HP. This power range covers small pumps, fans, and conveyors that benefit from speed control. The output stage modulates frequency up to 590 Hz, allowing high-speed spindle or centrifugal loads to run well above the synchronous speed of the mains supply. Dynamic braking is supported through an internal chopper that activates at 728 V DC, quickly dissipating regenerated energy during deceleration. Because the VVC+ scheme tracks motor flux, the drive can switch an unlimited number of times per minute without reducing thermal margins. A phase imbalance limit of 3% protects the semiconductors from uneven loading.
Protective logic issues a high-voltage warning at 810 V DC, followed by an overvoltage alarm at 820 V DC to prevent bus damage. For vector control at low speeds, flux-boost operation is available up to 300 Hz, after which the algorithm reverts to standard pulse-width modulation. Motor connections can use shielded cable runs up to 150 m long or unshielded runs up to 300 m long while maintaining compliance with the drive’s dV/dt criteria. The output slew rate is limited to 0.862 kV/µs when measured across a 5-meter lead at 480 V, reducing stress on motor insulation. Power cycles are limited to two per minute so that inrush current does not cause premature fatigue in the bus capacitors.
