Product Description:
The FC-301P18KT2131F0576 is a variable frequency drive engineered by Danfoss within the VLT FC 301 Automation Drives series. The device processes three-phase AC supply power and produces a regulated output to control induction motor speed in conveyors, pumps, and material-handling equipment. Its integrated automation features allow direct connection of analog, digital, and relay signals, so a separate PLC can be omitted or its role reduced in smaller panels. This arrangement suits variable-speed applications that need direct I/O handling at the drive level.
The drive uses three-phase power and accepts input from 200 – 240 VAC lines, with a permitted phase imbalance of 3.0%. Its installation category is Overvoltage Category III, so it tolerates industrial switchgear transients. Internally, the inverter section delivers up to 18.5 kW or 25 HP to the motor, matching mid-range process machinery. One analog output is provided, and its resolution of 12 bit combined with 0.5% FS accuracy allows proportional speed or torque feedback to external controllers. Two digital outputs are available for status signaling, while a digital input rated for 28 V DC accepts run or preset commands without additional interface modules.
Transistor channels source up to 40 mA each for indicator lamps or opto-isolated relays. A pulse or frequency port provides a logic-level square wave up to 32 kHz for tachometer-style feedback or encoder emulation up to 110 kHz when a higher pulse rate is needed. Cable routing guidelines limit shielded motor leads to 50 m and allow 75 m when unshielded, which helps reduce reflected-wave stress on the output stage. Dedicated relay contacts switch 240 V AC at 2 A or 60 V DC at 1 A, so auxiliary pumps, brakes, or dampers can be actuated directly from the drive.
