Product Description:
The FC-301P1K5T2131B1125 is an AC variable-frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. It converts 200–240 VAC three-phase power into a modulated output that controls the speed of compatible induction motors. This capability supports variable-speed operation in conveyors, pumps, and general process equipment used throughout industrial automation systems. Closed-loop control uses a 12-bit analog input to process reference or feedback signals with sufficient resolution for stable speed regulation.
The drive has a throughput efficiency of 0.96, limiting the portion of supplied electrical energy lost as heat within the unit. Its continuous output current is rated at 7.5 A, allowing it to operate motors with an output rating of up to 1.5 kW. The DC link issues an early warning at 405 V DC and trips at 410 V DC to protect internal capacitors from excessive voltage. Two digital outputs provide start, stop, alarm, or status signals and share a maximum sourcing capacity of 40 mA. Their minimum pulse width is 4.5 ms, allowing typical PLC inputs to recognize state changes reliably without requiring additional signal conditioning.
The IGBT power section supports carrier frequencies of up to 32 kHz, enabling the controller to produce a finely modulated waveform for the connected motor. Full-load input current can reach 6.8 A, so the upstream wiring and protective devices must accommodate that demand. Power conversion produces 82 W of heat loss under the stated operating conditions, requiring adequate airflow around the enclosure to keep internal components within their permitted temperature range. Shielded motor cables may extend up to 50 m to support electromagnetic compatibility, while unshielded motor cables may reach 75 m without exceeding the drive’s output filtering limits. Maintaining the appropriate cable type and routing helps control electrical noise and voltage stress at the motor terminals. The output terminals should be connected using conductors suitable for the operating current, cable length, and installation environment.
