The Fuji Electric FRN0046G2S-2GU is a FRENIC-MEGA series AC drive rated for 15 hp at 46.2 A output, accepting 200 to 240V AC single- or three-phase input and delivering three-phase output up to 500 Hz. The 200% starting torque at 1 Hz means it can break away a loaded conveyor or hoist without oversizing the drive — a real advantage on high-inertia starts where other drives would stall or need a torque boost parameter tweak. The built-in Ethernet port (standard, not an option card) simplifies integration into plant networks for monitoring and parameter access, and the LCD keypad with LED display gives local control and programming without a laptop.
The 46.2 A maximum output current at 240V AC defines the motor full-load amp limit — size the motor branch circuit and output conductors for at least this continuous rating. The 200% torque at 1 Hz (200% starting torque) is the low-speed breakaway capability; it's not a continuous rating, but it tells you the drive can deliver double rated torque momentarily to get a load moving, then settle to the continuous 15 hp curve. Output frequency range of 25 to 500 Hz covers standard induction motors (typical 50/60 Hz base) up to high-speed spindle applications. For a 4-pole motor at 400 Hz, you'd get roughly 12,000 RPM — useful for pumps, centrifuges, or machine spindles, but verify the motor's mechanical balance and bearing rating above 60 Hz. The NEMA 1 open enclosure (IP20 equivalent) is for indoor, dry locations — no washdown, no dust. Pair it with a separate NEMA 4X or 12 enclosure if the environment is wet or dirty. The compact/heat sink style means the heat sink is integral to the frame; mount it vertically with clearance above and below for natural convection cooling.
I/O and Control Flexibility
The drive carries (9) digital inputs, (6) digital outputs, (3) analog inputs, and (2) analog outputs, plus (2) safety inputs — enough for a basic speed/start/stop with feedback and a safe torque-off loop without an external safety relay. The safety inputs accept a 24V DC signal from a safety-rated switch or light curtain; wire them to the drive's safety terminals and configure the drive to disable output on loss of signal. Adjustable acceleration and deceleration times from 0 to 6,000 seconds give fine control over ramp profiles — useful for soft-starting conveyors or ramping down high-inertia loads without tripping on overvoltage. The drive supports both constant and variable torque applications; set the motor nameplate data and let the drive auto-tune the motor parameters for best efficiency.
Approvals include UL (UL508C), cUL, CSA (C22.2 No. 14), CE (EN61800-5-1), and RoHS compliance (2002/96/EC). These cover North American and European regulatory acceptance; the CE mark under EN61800-5-1 means the drive meets the harmonized safety standard for power drive systems, which is the typical requirement for machinery placed on the EU market.
