Product Description:

The FC-301P2K2T2134L2935 is a variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. By synthesizing a controllable AC waveform from the DC link, it lets PLCs vary motor speed, ramp torque smoothly, and apply dynamic braking, all of which are routine requirements in conveyors, centrifugal pumps, and small compressors. The compact chassis and integrated keypad allow direct panel mounting, so installers can add closed-loop motor control to machines where cabinet space is limited.

At the power stage, the drive supplies a continuous mechanical output of 2.2 kW, matching applications that need roughly 3 horsepower. It accepts a three-phase mains voltage range of 200–240 VAC and draws 9.5 A of line current when fully loaded. The inverter can deliver up to 10.6 A to the motor terminals, giving headroom for transient torque demands. Electrical conversion is efficient; at rated current, the unit reaches an efficiency of 0.96, keeping panel heat low and reducing ventilation requirements. Vector control is supported across a fundamental frequency range that extends to 590 Hz, so high-speed spindles or fan impellers can be driven without external gear multiplication.

The energy classification of IE2 verifies the drive’s compliance with international efficiency targets. Internally, a DC-link warning activates at 405 V DC to guard against excessive regeneration. Continuous duty is permitted up to an elevation of 1000 m and an ambient temperature of 45 °C without derating. Heat dissipation is limited to 116 W at full load, a value that simplifies enclosure cooling calculations. The digital I/O tolerates 28 V inputs, and the transistor output supplies up to 40 mA for direct interfacing with sensors and relays.
