Product Description:

The FC-301P22KT4E20H1XG is an AC variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. It converts constant-frequency mains power into a pulse-width-modulated output so plant controllers can regulate motor speed and torque without mechanical throttling. In automated pump, fan, or conveyor systems, this electronic speed control helps match process demand, reduce energy use, and limit mechanical wear. The drive can also support applications that require consistent motor performance as operating conditions change.

The inverter provides a continuous electrical output of 22 kW, equivalent to 30 HP when driving standard induction motors. It accepts mains power within the 380–480 VAC range and is intended for three-phase power, eliminating the need for external phase conversion. An IP20 chassis enclosure protects internal components from incidental contact, so the unit must be housed in a ventilated panel. Heat sink monitoring and current-limiting algorithms protect the IGBT bridge from overtemperature and overload faults. The drive maintains speed, torque, and internal PID control modes for closed-loop operation in compatible systems.

Cabinet integration is supported by normal cabinet mounting for A, B, and C frames, which accommodates common switchgear sections and permits side-by-side installation above 40 °C when the applicable derating tables are followed. Local setup and override commands are handled through the graphical local control panel, whose backlit screen shows real-time kilowatt, ampere, and alarm data. Conducted emission control is provided by the factory-installed RFI Class A1/B filter, supporting compliance with industrial electromagnetic compatibility standards. The unit has no brake chopper, so an appropriate external braking solution or a mechanical method is required when rapid emergency deceleration is needed. This arrangement allows the stopping method to be selected according to the motor load, inertia, and required deceleration time.
