Product Description:
The FC-301PK75T4134L2648 is an AC variable-frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. Within the VLT AutomationDrive FC product group, this unit modulates three-phase power to regulate induction motor speed and torque in conveyors, pumps, and other automated machinery. Its control architecture supports adjustable motor operation in systems that require coordinated acceleration, deceleration, and steady-speed performance. The drive is designed for installation in a standard control cabinet, where its connections remain accessible for power, motor, and control wiring.
The drive accepts a three-phase mains input of 380 to 480 VAC at 50 or 60 Hz with a tolerance of ±5 percent. It delivers a nominal shaft power of 0.75 kW, which corresponds to 1.0 HP. Full-load efficiency reaches 0.96, reducing internal heat generation during continuous operation. The adjustable output frequency ranges from 0 to 590 Hz, while flux-mode operation is available from 0 to 300 Hz for constant-torque applications. Output voltage can be adjusted from zero to 100 percent of the supply voltage to suit the connected motor. The analog output channel provides a 0/4–20 mA feedback signal for remote indicators or control equipment. Six digital inputs accept 0 to 24 V DC commands for functions such as starting, stopping, and selecting preset speeds. A pulse input supports signals up to 110 kHz for high-speed reference or feedback applications.
On 380 to 440 V lines, the inverter draws 2.2 A from the supply and provides up to 2.4 A of output current to the motor terminals. Semiconductor power loss is limited to 46 W, which helps control heat accumulation inside the cabinet. Recommended motor cable lengths extend to 50 m with shielded cable and 75 m with unshielded cable. Proper shield bonding helps limit electromagnetic interference when shielded motor leads are used. Phase symmetry supports balanced loading across the three-phase mains supply and promotes stable motor operation. Control and power cables should be routed with suitable separation to reduce electrical noise in analog and pulse signals.
