Product Description:
The FC-301P5K5T2131X7266 is produced by Danfoss as part of the VLT FC 301 Automation Drives series. Within an automated line, this unit functions as the adjustable-speed interface between the plant power supply and an AC induction motor. This arrangement allows machine controllers to match shaft speed and torque to real-time process demand while avoiding the abrupt operation associated with direct-on-line switching.
The inverter connects to plant power in the 200–240 VAC range and accepts three-phase power, so no phase conversion is required. Its continuous output rating of 5.5 kW corresponds to a mechanical capacity of 7.5 HP. Each digital input tolerates up to 28 V DC, providing headroom that helps protect the logic circuits from field-wiring transients. Digital outputs can switch feedback signals at 32 kHz, making them suitable for high-resolution pulse trains and other fast control signals. A mains imbalance tolerance of 3.0% helps keep the DC link stable when the phase voltages differ. Category III overvoltage classification indicates that the insulation spacing is suitable for fixed industrial installations. The power lugs require a tightening torque of 1.8 N·m to maintain low-resistance electrical joints during machine vibration.
The synthesized output waveform can reach 590 Hz, while flux optimization is limited to 300 Hz. These frequency limits support extended-speed constant-torque duty or field-weakening operation, depending on the connected motor and application. The short-circuit withstand capability is 100,000 A RMS, allowing the drive to operate on feeders protected by high-capacity fuses. Installation requirements permit no more than two power-ups per minute to reduce inrush stress on the input stage and DC-link components. Motor leads may extend up to 50 m when shielded or 75 m when unshielded, providing flexibility for installations with remote motors. Copper conductors with cross-sectional areas up to 10 mm² fit the output terminals, allowing appropriately sized motor wiring to be secured directly to the drive.
