25B-D2P3N104 — 525 Series AC Drive, 480V Three-Phase, 0.75 kW, EtherNet/IP

The 25B-D2P3N104 is a 0.75 kW / 1 HP variable frequency drive from the 525 series, configured for 380–480V AC three-phase input with 2.3A output current. Like the rest of the 525 platform, it ships with dual-port EtherNet/IP built in, sensorless vector control, hardwired Safe Torque Off, and a peripheral option port — at a power rating small enough to fit into compact OEM machine designs without sacrificing network connectivity.

Small Drives, Full Network Access

It's tempting to assume that low-power drives don't need the same connectivity as larger industrial units, but small drives are often the ones embedded deepest into OEM machine designs — multiple axes per machine, distributed across a compact footprint, each one needing status visibility and remote control just as much as a single large drive would. The 25B-D2P3N104 brings the full 525 feature set down to 0.75 kW specifically for this reason: a machine with six small drives gets six fully network-visible nodes rather than six drives that need separate communication cards or remain isolated from the control system.

The dual ports support DLR ring topology natively, which matters disproportionately on machines with many small drives clustered together — daisy-chaining through each drive's two ports eliminates the switch hardware that would otherwise be needed at every drive location.

FAQ

Q: Does SVC mode work reliably at this power rating?

Yes, with a completed autotune. Enter accurate motor nameplate data and run the autotune routine before enabling SVC — without it, low-speed torque behavior is unpredictable regardless of drive size.

Q: Can this drive run multiple small motors from one unit?

No. Each drive is designed to control one motor. Running multiple motors from a single drive output voids overload protection accuracy and risks unbalanced load sharing between motors.

Q: Is a line reactor necessary at this power level?

Generally not required for a single small drive on a stable supply, though it remains good practice on installations with multiple drives sharing a transformer or where supply quality is marginal.

Q: How is the IP address assigned on first connection?

Default is BOOTP. For production use, set a static IP via the HIM before connecting to the network to avoid address reassignment after a power cycle.
