Product Description:

The FC-301P1K1T2134L2701 is an AC variable frequency drive produced by Danfoss within the VLT FC 301 Automation Drives series. Designed for three-phase induction motors in factory machinery, the unit converts fixed line power into a modulated output that allows control systems to regulate motor speed and torque without mechanical throttling. In automated conveyors, pumps, and compact process equipment, the drive acts as the interface between low-level PLC commands and the electrical power stage of the motor.

The drive connects to a three-phase supply rated at 200–240 VAC, allowing installation on standard low-voltage industrial feeders. Inside the converter, the DC link and IGBT bridge support a continuous mechanical output of 1.1 kW, which corresponds to 1.5 HP. When the load reaches this level, the inverter can deliver a steady motor phase current of 6.6 A, while the maximum input current is 5.9 A. These electrical limits help determine the circuit breaker size, cable cross section, and thermal dissipation required in the enclosure. Analog process feedback is carried on a 12-bit output channel. Control wiring can have a cross-sectional area of up to 1.5 mm² to minimize voltage drop across panel wiring distances.

The drive has a conversion efficiency of 0.96, resulting in a heat loss of only 63 W at full load. Reactive components inside the front end produce an apparent power demand of 2.63 kVA, which is useful when sizing transformers or generators. On the motor side, the inverter supports carrier-based flux mode up to 300 Hz and can accommodate speed commands up to a maximum output frequency of 590 Hz, enabling operation with high-speed spindles or oversynchronous fans. Start-stop cycling is limited to two power-ups per minute, and the line voltage imbalance must remain below 3%. Shielded motor leads can extend up to 50 m, while unshielded runs may reach 75 m without drive derating.
