The FRN0009G2S-4GU: The 9 A output current and 5 hp rating define the motor frame size this drive can handle — a standard 5 hp IEC or NEMA motor on a 400 V class supply. The 380-480 VAC input range with +10%/-15% tolerance covers nominal 400 V and 460 V grids without a transformer. Output frequency spans 0.1 to 120 Hz, which covers most fixed-speed to moderate-speed fan/pump applications. The NEMA 1 enclosure is suitable for indoor, non-condensing environments; the open-style chassis means it is intended for panel mounting, not standalone wall mount.
This drive carries a lifecycle stage of current, meaning Fuji Electric continues to manufacture it. No last-time-buy or phase-out notice applies.
I/O and control interface
The drive provides 7 digital inputs and 3 analog inputs, plus 5 digital outputs and 2 analog outputs. It accepts remote contact closure for start/stop and supports keypad or remote control. The LCD/LED display shows motor speed with percent, alarm codes, menus, and function codes; a separate digital readout cycles through output frequency, current, and voltage. Dynamic braking is built in, though no internal brake chopper is included — an external braking resistor is needed for overhauling loads.
Protection and compliance
Protection circuits cover drive thermal overload, motor thermal overload, overvoltage, undervoltage, phase failure, phase-to-phase and phase-to-ground short circuit, and over-braking. The drive is listed to UL508C, CSA C22.2 No.14, and EN50178-1997, covering North American and European safety standards for industrial control equipment.
