Product Description:
The FC-301P22KT4131B3716 is an AC variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. Within automated machinery, it converts the fixed-frequency line supply into a variable-frequency output so induction motors can follow speed or torque commands, reducing energy use and mechanical wear. The unit is intended for three-phase installations that require adjustable motion control in conveyors, pumps, processing equipment, and other automated systems.
The power section accepts a line voltage of 380–480 VAC at 50/60 Hz ±5% and provides a rated motor output of 30 HP, or 22 kW. Flux-mode operation can be selected for applications requiring motor magnetization at frequencies up to 300 Hz. The inverter can increase the output frequency to 590 Hz for compatible high-speed motors and spindle applications. A displacement power factor of >0.98 minimizes reactive current, while the true power factor remains above 0.9 under nominal load. Four digital inputs accept signals up to 28 V DC, allowing direct connection to compatible PLC outputs. A single analog output with 12-bit resolution reports process values to supervisory control systems.
The overvoltage trip limit is set at 820 V DC to protect the internal DC-link components when regenerative energy raises the bus voltage. Pulse-train references are accepted at frequencies up to 110 kHz, supporting precise command tracking in motion-control applications. Motor cables may be unshielded for runs up to 75 m, while shielded motor cables may extend up to 50 m without exceeding the stated electromagnetic compatibility limits. The analog feedback channel sources or sinks current within a range of 0/4–20 mA, enabling connection to standard industrial instruments and control equipment. These interfaces allow the drive to exchange reference commands, operating data, and process feedback with the surrounding automation system.
