Drive Selection Memo
The Fuji Electric FRN0288G2W-2GU is a 100 hp variable-frequency drive from the FRN series, delivering 283 A maximum output current on a 200 to 230V AC three-phase input. Output frequency spans 0 to 500 Hz, covering standard induction motors and higher-speed spindle applications. It ships as an open (IP00) enclosure with a compact/heat sink style — intended for panel mounting where the heat sink protrudes for airflow, not for standalone floor placement. The built-in LCD/LED keypad provides readouts for motor speed, output current, output frequency, and output voltage; the stop-key lockout prevents unauthorized shutdown.
Ratings and What They Mean for Fit
The 283 A maximum output current at 230V AC is the headline number — it governs the motor full-load amp rating. At 100 hp (approx 75 kW) on 230V, this drive is sized for a 100 hp 4-pole induction motor drawing around 240-250 A FLA, leaving headroom for overload. The 180% starting torque (presumably for 60 seconds) means it can break away high-inertia loads like centrifuges or crushers without oversizing. Constant and variable torque modes let it handle both conveyors (constant torque) and fans/pumps (variable torque) from the same unit. Dynamic braking is included, but no brake chopper is inside — you need an external braking resistor for overhauling loads. The Ethernet port supports networked monitoring or control; the 3 analog and 11 digital inputs plus 11 analog and 6 digital outputs give flexibility for feedback and sequencing without an expansion I/O module.
Mounting and Integration
The open (IP00) enclosure means it is designed for a clean, dry electrical enclosure — not for washdown or outdoor use. Overall dimensions are 29-1/8 in high by 14 in wide by 10-5/8 in deep.
