Product Description:

The FC-301P15KT2131H4559 is a variable-frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. Installed between the mains supply and an induction motor, it converts fixed line power into a modulated output that allows industrial controllers to regulate motor speed and torque. This functionality supports conveyors, pumps, and other automated equipment that must respond to changing process demands. Closed-loop motor control helps the connected machinery maintain the commanded output under varying operating loads.

The drive accepts 200–240 VAC from a three-phase power supply and can deliver up to 15 kW, equivalent to 20 HP, at the motor terminals. Its inverter section supports an output frequency of up to 590 Hz for motors used in high-speed applications. Each of the two analog inputs draws no more than 30 mA and tolerates a signal range of ±20 V. A 40 mA digital output and a relay rated for 240 V AC at 2 A support basic control and sequencing functions. The drive generates a high-voltage warning when the DC link reaches 405 V DC and issues an overvoltage alarm at 410 V DC to protect the power section.

For vector-based motor regulation, the drive supports flux-mode operation at frequencies up to 300 Hz. Incoming feedback signals are sampled with 10-bit resolution, while outgoing analog references use 12-bit resolution to provide finer control signals. Dynamic braking is managed through the DC bus, and the brake chopper activates at 390 V DC to dissipate excess regenerative energy. The installation can use up to 50 m of shielded motor cable, providing additional protection against electromagnetic interference in sensitive applications. When unshielded motor cable is suitable for the installation, the permitted cable length increases to 75 m. These cable allowances provide flexibility when the drive and motor must be installed in separate areas of a machine or production line.
