The Fuji FRNF25E1S-7U is a FRENIC-MULTI core drive, single-phase 230V input, rated for 1/4 HP output. This is the base-model VFD in the FRENIC-MULTI family — no fieldbus option card, no built-in PLC, just straight variable-frequency motor control for small pumps, fans, or conveyors on a 1-phase supply.
Wiring practice note
Single-phase 230V input on L1/N. Motor output to a 1/4 HP 3-phase motor — verify the motor nameplate is wound for 230V 3-phase on the drive output. No DC choke or braking resistor included in the base drive; add an external braking resistor for overhauling loads.
