Product Description:

The FC-301P1K1T4134F6099 is an AC variable frequency drive manufactured by Danfoss within the VLT FC 301 Automation Drives series. The unit modulates fixed-frequency, three-phase mains power supplied to an induction motor, allowing speed and torque to be matched to process demands rather than requiring the motor to run at line frequency. The drive serves as a controller for pumps, fans, and conveyors in industrial automation systems where energy savings and precise motor regulation are required.

At the input terminals, the drive accepts three-phase 380–480 VAC utility power and draws 2.7 A when operating near its nominal load. The inverter section can deliver up to 3.0 A to the motor, which corresponds to a motor output rating of 1.1 kW or 1.5 HP. These ratings support compatibility with small IEC motors used on auxiliary equipment. Conversion efficiency is 0.96, so most of the absorbed power reaches the motor while minimal heat is dissipated inside the enclosure. Its three-phase topology maintains balanced loading on the mains conductors and supports controlled operation across the drive’s intended power range.

During dynamic operation, the inverter can deliver an apparent power of 2.1 kVA at 400 V and provide an output frequency of up to 590 Hz. A dedicated flux-mode ceiling of 300 Hz supports sensorless vector control with lower switching losses. Internal power loss is limited to 58 W at maximum load, and the design permits up to two power-ups per minute to protect the inrush components. The control interfaces provide a 12-bit analog output for process feedback and two digital outputs that can each source up to 40 mA for relays or indicators. The supported motor connection length is 50 m with shielded cable or 75 m with unshielded cable, allowing reliable operation when the motor is installed at a distance from the drive. These cable limits help reduce electrical interference and maintain stable motor control on distributed machinery lines.
