Product Description:

The FC-301P22KT2134L2943 is a variable frequency drive manufactured by Danfoss as part of the VLT FC 301 Automation Drives series. It converts a 200–240 VAC input into a controlled three-phase output for induction motors used in conveyors, pumps, and ventilation equipment. By modulating voltage and frequency through pulse-width control, the module allows plant controllers to adjust speed and torque without mechanical control devices. The drive uses the mechanical platform associated with series identifier 301, enabling compatible mounting and programming practices across the series.

Delivering a continuous output of 22 kW, equivalent to 30 HP, the drive supports midrange machinery that requires reliable acceleration and braking. It operates on three-phase power and can raise motor frequency to 590 Hz for high-speed spindles; its dedicated flux mode is limited to 300 Hz for sensorless vector control. One analog output with 12-bit resolution supplies proportional speed or load data to supervisory PLCs, while two digital or pulse outputs handle status or tachometer functions. The logic interface accepts commands up to 28 V DC, and each digital output can source 40 mA, supporting standard 24 V control wiring. These interfaces allow the drive to exchange operating commands and status signals with common industrial control equipment.

Protective circuits monitor the DC link throughout operation. Braking energy is directed into the bus at 390 V DC, a high-voltage warning activates at 405 V DC, and an overvoltage alarm trips at 410 V DC to protect the connected equipment. Pulse trains for external counters reach a maximum frequency of 110 kHz with a minimum pulse width of 4.5 µs, allowing accurate feedback across a wide speed range. Motor leads may extend up to 50 m when shielded or 75 m when unshielded while maintaining electromagnetic compatibility. The permitted lead length depends on the cable shielding method, so routing and cable selection must account for the installation layout.
