Product Description:
The FC-301P5K5T4131B1003 is an AC variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series and included in the VLT AutomationDrive FC product group. It accepts industrial mains power and delivers a regulated three-phase output to automate pump, fan, and conveyor motors in distributed control systems. Onboard terminals provide analog, digital, and pulse signals so the unit can interface directly with PLCs or stand-alone sensors. This connectivity allows motor speed adjustment without external contactors or soft starters.
This model is rated for 5.5 kW of continuous mechanical power, equivalent to 7.5 HP, when supplied from a 380–480 VAC three-phase power supply. Carrier modulation allows the inverter to produce output frequencies up to 590 Hz, while its analog feedback channel resolves setpoint data with 12-bit resolution. A 10 V reference rail supplies 15 mA for potentiometers, and the 24 V control rail can supply 200 mA to external logic coils. Digital inputs tolerate 28 V DC, and each digital output can sink 40 mA to signal relays or counters. In flux-optimized mode, torque commands remain linear to a ceiling of 300 Hz. The high-speed pulse input registers encoder feedback up to 110 kHz, enabling tight closed-loop control.
Protective circuits activate at a flux-mode limit of 300 Hz, issue a high-voltage warning at 810 V DC, and initiate an overvoltage trip at 820 V DC. The brake chopper engages when the bus voltage reaches 728 V DC. The drive may be energized twice per minute, so more frequent power cycling should be avoided. Internal power-factor correction maintains a displacement factor of at least 0.9 under rated load. Shielded motor leads can extend to 50 m, while unshielded leads can extend to 75 m without compromising EMC compliance. Motor braking current flows through a flux-matched resistor, and the 301 series identifier supports dimensional compatibility across the FC 301 platform.
