Product Description:
The FC-301P11KT4131F5494 is a variable-frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. The unit converts fixed three-phase mains power into a controlled AC output, allowing plant controllers to adjust induction motor speed and torque without mechanical throttling devices. This electronic control can match motor operation to changing process demands in conveyors, pumps, fans, and general-purpose machinery. Programmable input and output channels allow external switches, sensors, and control systems to exchange commands and status signals with the drive. Analog signal scaling also supports proportional references from process instruments that monitor variables such as pressure, flow, or speed.
The drive has a continuous output rating of 11 kW, which corresponds to 15 HP for use with midrange production motors. Its input section accepts line voltages from 380 to 480 VAC and synchronizes with the utility frequency before pulse-width modulation, so an external transformer is not required when the supply remains within this range. The inverter can deliver output frequencies as high as 590 Hz, supporting compatible high-speed spindles, fan wheels, and other applications that require operation above standard line frequency. Each analog input is sampled with 10-bit resolution, providing 1,024 incremental levels for interpreting proportional feedback and reference signals. This resolution helps the internal regulator respond to small changes in an attached sensor signal while maintaining stable motor control.
The DC-link supervisor activates the brake chopper at 778 V DC when regenerated energy causes the internal bus voltage to rise. It generates a warning at 810 V DC, giving the control system an indication that the link voltage is approaching the shutdown threshold. An overvoltage trip occurs at 820 V DC to protect the inverter power stage from excessive electrical stress during regenerative events. These staged responses allow braking energy to be addressed before the voltage reaches the trip point. The control terminals also provide a 24-volt supply capable of sourcing up to 200 mA for compatible sensors, contact relays, and other low-power control devices. Connected equipment can use this auxiliary source while exchanging signals through the drive’s programmable inputs and outputs.
