Product Description:

The FC-301P7K5T4134F5109 is a variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. It converts three-phase utility power into a modulated output that controls induction or permanent-magnet motors. The unit is used in automated production lines where accurate speed and torque regulation are required for pumps, conveyors, and similar machinery. Its regulated output allows connected equipment to operate at speeds suited to changing process demands without relying on mechanical flow or speed controls.

During operation, the inverter can deliver up to 7.5 kW of electrical power, corresponding to a motor output of 10 HP. It accepts line supplies from 380 to 480 VAC on a nominal grid frequency of 50/60 Hz ±5%. The drive can produce output frequencies as high as 590 Hz for motors designed to operate above their nominal synchronous speed. Power is supplied through three phases, and the displacement power factor remains above 0.98 while the true power factor is at least 0.9, limiting unnecessary reactive current. Shielded motor cables can extend up to 50 m, while unshielded cables can extend up to 75 m without derating. Relay 1 can switch 2 A at 240 VAC, and the Safe Torque Off input draws 50 mA rms to provide an independent motion-disable channel for safety circuits.

Control and monitoring are handled through analog, digital, and pulse I/O. An analog terminal supplies 0/4–20 mA for external meters, and the reference node provides 10.5 V ±0.5 V for potentiometer setpoints. Digital outputs can supply up to 40 mA, while pulse inputs accept frequencies reaching 110 kHz for high-resolution speed commands. The control card operates from a 24 V rail with a tolerance of +1/-3 V, and its digital inputs tolerate up to 28 V DC. These interfaces support connections to standard PLC I/O, external meters, potentiometers, and pulse-based command devices used throughout automated machinery.
