Drive specs for the line-down decision
The Fuji FRN0261G2W-4GU is a 200 hp variable frequency drive from the FRENIC-Eco series, rated for 240 A continuous output on a 380-480 VAC three-phase supply. That 240 A is the number that governs the motor branch circuit — match it to the full-load amp rating of your 200 hp motor, not the nameplate horsepower alone. The drive accepts 380-480 VAC +10%/-15% and delivers 0-460 VAC output over a 0.1 to 120 Hz frequency range, so it covers 50/60 Hz line supplies and can overspeed a standard motor if the load allows. This is a variable-torque drive, meaning it's optimized for centrifugal loads like fans and pumps in HVAC applications. The starting torque is 50% at 1 Hz, which is typical for a variable-torque curve — enough to accelerate a fan wheel unloaded, but not for a high-breakaway conveyor or extruder. If your load requires constant torque across the speed range, this drive will need derating; the FRENIC-Eco series has a constant-torque sibling that would be the correct pick.
I/O and control — what connects where
The drive has 7 digital inputs, 3 analog inputs, 5 digital outputs, and 2 analog outputs. No Ethernet port is included. Control is via the keypad or remote contacts. The keypad shows motor speed in percent, output frequency, output current, output voltage, alarm codes, and function codes — enough for commissioning and basic fault-finding without a laptop. For remote operation, the drive accepts a dry-contact start/stop signal. The dynamic braking circuit is present, but no brake chopper is included — if you need rapid deceleration on a high-inertia fan, you'll add an external braking unit and resistor.
