The FRN003F1S-2DY is a Fuji FRENIC-ECO Pump (F1-DY) variable frequency drive rated for 3 HP on a 3-phase 230 VAC supply. This is a dedicated pump drive variant, meaning the control firmware is pre-configured for pump-specific functions like PID setpoint control for constant pressure or level regulation, and includes features such as sleep/wake and flow compensation. The 230 V class limits it to North American light-industrial or commercial applications; for 400 V class installations, the corresponding F1S-2EY variant would be the correct selection.
The 3 HP / 230 V rating defines the maximum continuous motor load this drive can handle in a variable-torque pump application. At 230 V, the drive's input current draw will typically be around 9-10 A, which sets the minimum branch-circuit protection and conductor sizing. The FRENIC-ECO series is designed for pump and fan loads, so the overload rating is likely 110% for 60 seconds — adequate for centrifugal pump start-up but not for high-inertia loads like a crusher or extruder. If the motor nameplate shows 3 HP at 230 V, this drive matches.
Integration notes
Mounts in a standard enclosure with IP20 protection; the control terminal block accepts 16-22 AWG for analog and digital I/O. The F1-DY firmware includes a built-in PID controller, so an external PLC is not required for basic pressure or flow control — the setpoint can be entered via the keypad or a 4-20 mA remote reference. Verify that the motor leads are shielded and the shield is grounded at the drive end only to avoid ground loops on the analog input.
