Internal Product Review
The FC-301P22KT4131G5121 is a Danfoss VLT FC 301 automation drive built for motor control on 380 - 480 VAC three-phase power. A 22 kW / 30 HP rating gives the unit strong application range for demanding industrial duty. A 160% overload class with a 1 min/10 min duty window stands out as a valuable performance margin for transient load conditions.

Product Description:
The FC-301P22KT4131G5121 is a Danfoss AC variable-frequency drive in the VLT FC 301 Automation Drives series. Within an automated plant, it modulates a fixed mains supply to control induction-motor speed and torque. This capability allows conveyors, pumps, and fans to respond to changing process demand instead of operating continuously at full speed. The unit is intended for automated systems that require adjustable motor control and integration with common industrial control equipment.
This model delivers a continuous output of 22 kW, making it suitable for midrange motor applications without requiring oversized switchgear. It accepts a 380–480 VAC three-phase power supply and tolerates a maximum mains imbalance of 3.0%, helping preserve motor torque when one phase experiences a voltage sag. Carrier modulation reaches 32 kHz, allowing the inverter to produce a controlled output waveform for the connected motor. The drive can command motor frequencies up to 590 Hz, while its auxiliary flux mode operates at frequencies up to 300 Hz for field-weakening applications. The unit permits one power-up per minute when repeated energy isolation is required. A 160% overload capacity is available for one minute within each ten-minute duty cycle, and thermal monitoring protects the power stage during these temporary torque demands. Shielded motor cables may extend up to 50 m, while unshielded cables may extend up to 75 m. The pulse-width modulation section maintains a true power factor of at least 0.9 during normal operation.
Grid performance is supported by a displacement factor greater than 0.98, which reduces reactive current drawn from the power supply. The analog output provides 12-bit resolution, allowing reference changes in increments of one part in 4,096. Logic terminals accept a high-state input of up to 28 V DC, making them compatible with common 24 V PLC output cards. The programmable transistor output can source up to 40 mA for external control or status circuits. Digital inputs also withstand up to 28 V DC, providing an operating margin above the nominal control voltage. These control interfaces support motor regulation, process feedback, and status signaling without requiring separate signal-conversion hardware.
