Drive selection memo
The Fuji Electric FRN0105G2S-4GU is a 60 hp variable frequency drive from the FRENIC-Eco series, rated for 85 A maximum output current on a 380-480V AC three-phase input. That 85 A figure is the one that governs motor sizing — it tells you this drive can continuously supply a 60 hp induction motor at full load without tripping on thermal overload. The input voltage tolerance of +10% / -15% means it rides through moderate sags on a 460V line without dropping out, which matters on HV AC applications like large HVAC fans or pumps where line stability isn't guaranteed. Output frequency spans 0.1 to 120 Hz, so it covers standard 50/60 Hz motors and can overspeed a 4-pole machine to about 3600 rpm for applications needing a bit more throughput. Starting torque is 50% at 1 Hz — enough for centrifugal loads like fans and pumps (variable torque profile), but not for high-breakaway loads like conveyors or extruders. For those, you'd want a drive with a higher torque rating at low speed.
Panel integration and wiring
This is an open-enclosure (NEMA 1) drive, so it's meant for indoor panel mounting where it won't see direct washdown or dust ingress. The blue heat sink style is the standard FRENIC-Eco industrial finish — nothing special, just the production color. Dimensions are 21-3/4 inches high by 12-5/8 inches wide by 10 inches deep, so plan for a panel that can accommodate that footprint plus bending radius clearance for incoming power and motor leads. Control wiring: it accepts 7 digital inputs and 3 analog inputs, plus gives you 5 digital outputs and 2 analog outputs. That's enough for basic speed reference (potentiometer or 0-10V), start/stop via remote contact, and feedback to a PLC or building management system. No Ethernet port is included, so if you need network connectivity, plan for an optional communication card or a standalone gateway. No brake chopper inside either — if you need dynamic braking for overhauling loads, you'll add an external chopper and resistor.
