Product Description:

The FC-301P11KT2134L2972 is an AC variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. It converts fixed mains power into a modulated output that lets controllers vary induction motor speed and torque in conveyors, pump skids, and general machinery. Within an automation cell, the drive operates as the power stage, taking commands from a PLC and regulating motor current so that mechanical motion follows the programmed profile.

This model delivers a continuous mechanical output of 11 kW, giving it sufficient capacity for medium-sized fan or compressor motors. The inverter accepts a nominal line voltage of 200–240 VAC from a three-phase power supply, drawing 16.6 kVA at 208 V and 18.4 kVA at 230 V. Efficiency at rated current is 0.96, so most of the input energy is transferred to the motor rather than dissipated as heat. Flux mode permits carrier frequencies up to 300 Hz, while normal operation supports vector or V/Hz control according to the selected parameter settings. Current-limited digital outputs protect downstream wiring, and a 24 V, 200 mA auxiliary source can power sensors without requiring an external supply.

The control interface provides one analog channel with 12-bit resolution, two digital pulse outputs, a single relay contact, and logic outputs rated at 40 mA. Motor overspeed protection is available because the synthesized waveform can reach 590 Hz, and this ceiling must align with the selected motor’s base frequency. Installation guidelines limit shielded motor leads to 50 m and unshielded motor leads to 75 m to maintain electromagnetic compatibility and help prevent voltage reflection. High-speed positioning or flow metering is possible because the pulse input stages capture encoder or flow meter signals at frequencies up to 110 kHz. This input capability allows the control system to process rapid signal changes during closed-loop operation at elevated process speeds.
