Product Description:

The FC-301P3K7T2131B8966 is a variable frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. It modulates three-phase power to regulate motor speed and torque in conveyors, pumps, and other automated machinery, allowing closed-loop control without mechanical throttling. The drive interfaces with standard industrial controllers through built-in analog, digital, and serial connections. These interfaces allow the unit to receive motor commands, report operating conditions, and exchange data with the surrounding automation system.

The inverter accepts a three-phase input of 200 – 240 VAC and draws 15 A continuously. It delivers 3.7 kW, or 5.0 HP, while supplying up to 16.7 A to the motor terminals. Its operating efficiency is 0.96, and heat dissipation is limited to 185 W at rated load. The synthesized output can reach 590 Hz, while vector-based flux mode is limited to 300 Hz for high-torque applications. The displacement power factor remains greater than 0.98, and the true power factor is at least 0.9. These power-factor values help limit reactive current and keep the input current closely aligned with the useful power delivered to the motor.

The unit has a short-circuit current rating of 100 kA RMS, making it suitable for supply circuits with high prospective fault current when installed with the required protective equipment. Its control circuits include a +10 V reference limited to 15 mA and a 24 V sensor bus rated for 200 mA. The digital outputs provide 40 mA, while the digital inputs tolerate as much as 28 V DC. A 12-bit analog output provides precise feedback signals to external indicators or compatible control equipment. Shielded motor leads can extend up to 50 m, supporting practical separation between the drive enclosure and the connected motor. Proper shielding and cable routing help reduce electromagnetic interference in nearby signal and communication wiring.
