Drive rating and fit
The FR-D740-120-W1 is a Mitsubishi inverter drive rated for 12 Amp continuous output, 7.5 HP, on a three-phase 400 V supply. That 12 A figure governs the motor FLA it can carry — match it to a 7.5 HP 400 V motor nameplate and the drive holds the zone without derating at 40 °C ambient.
