Product Description:
The FC-301PK55T4134G0657 is an AC variable frequency drive produced by Danfoss within the VLT FC 301 Automation Drives series. As a member of the VLT AutomationDrive FC product group, the unit modulates three-phase mains power to regulate induction motor speed in conveyor, pump, and fan applications within industrial automation. The drive fits into control panels where space is limited. By using current-controlled IGBT switching and integrated motor protection, it replaces mechanical throttling devices while delivering precise torque control across a broad speed range.
Input power compatibility spans 380–480 VAC. Its motor output is rated at 0.55 kW, which corresponds to 0.75 HP. The rectifier and DC-link section activates braking at 728 V DC, while the drive issues a high-voltage warning at 810 V DC and an overvoltage alarm at 820 V DC to protect the IGBTs. The control electronics accept digital commands up to 28 V DC, and the safe torque off circuit draws 50 mA RMS from the 24 V supply. The three-phase power input must remain within a 3.0% phase imbalance to avoid additional derating. Efficiency meets the IE2 classification, and the drive supports a flux-oriented torque rise time of 1 ms or a rise time of 10 ms when VVC+ control is selected.
Full current is available at ambient temperatures up to 45 °C, and altitude derating is not required at elevations up to 1000 m. Motor wiring may extend to 50 m with shielded cable or 75 m with unshielded cable; additional output filters are required for longer runs. Control terminal blocks accommodate conductors ranging from 0.25 mm² to 1.5 mm², allowing suitable cable sizes to be selected for analog, digital, and safe torque off connections. Long motor cables can increase reflected energy at the inverter, so the stated cable limits and filtering requirements must be observed during installation.
