The Mitsubishi FR-D710W-025-NA is a FR-D700 series micro drive rated 2.5 Amp, 1/2 HP on single-phase 100 V input, per the US/CA/MX Specification design variant. This is the smallest frame in the D700 family, sized for fractional-horsepower loads like small conveyors, pumps, or fans where the incoming supply is 100 V single-phase — common in light commercial or residential applications in North America.
The FR-D700 series remains a current catalog line from Mitsubishi, so the FR-D710W-025-NA is the correct active part for this power class and voltage. For a line-down replacement or BOM freeze, this is the direct drop-in.
Panel fit and wiring constraints
Single-phase 100 V input means the drive connects to L and N on a 100 VAC supply — no step-down transformer needed for that voltage class. The output is three-phase 100 V for the motor. Verify the motor winding configuration: a 200 V-rated motor on this drive would require a reconnection to delta for 100 V operation, or a dedicated 100 V motor. The FR-D710W-025-NA is not a direct mechanical substitute for the FR-A740 series drives (which are 3-phase 200 V class, larger frame, heavier at 3.24+ kg). Panel cutouts and mounting hole patterns differ; rewiring and a new panel layout would be required to swap between these families.
