The Mitsubishi FR-D740-022-EC is a 0.75 kW inverter from the FR-D700 series, designed for three-phase 380-480 VAC input and delivering 0.2-400 Hz output. It carries a 150% overload capacity for 60 seconds, so it handles short-duration load spikes on pumps, fans, or general-purpose conveyors without tripping. The built-in PID controller (V/f control mode) means you can close a loop on pressure or flow without an external controller — saves a panel slot and one SKU on the BOM. IP20 enclosure suits it for a clean, dry cabinet — not washdown or outdoor. Mount it inside a standard IP54 panel and it's fine. RS485 Modbus RTU is onboard, so it talks to a PLC or HMI without an option card; that's another slot saved.
The 0.75 kW rating at 380-480 V three-phase matches a standard 1 HP (0.75 kW) induction motor. The 2.2 A output current is the continuous rating at 400 V — size your motor FLA against that. The 150% overload for 1 minute covers starting current and momentary overloads, but sustained overloads above 100% will trip the thermal model. Acceleration and deceleration times are adjustable from 0.01 to 3600 seconds, so you can ramp a high-inertia fan up slowly without a braking resistor.
