PRODUCT DETAILS
25A-E022N104 — 525 Series AC Drive, 480V Three-Phase, 11 kW / 15 HP
The 25A-E022N104 is an 11 kW / 15 HP variable frequency drive from the 525 series, accepting 380–480V AC three-phase input and delivering 22A continuous output current. It carries the full 525 platform feature set standard at this power level: dual-port EtherNet/IP with DLR support, sensorless vector control, hardwired Safe Torque Off, and a peripheral option port. At 15 HP, this drive frame size handles a meaningful range of industrial loads while keeping the same network-native architecture found across the smaller 525 ratings.

11 kW in the 525 Frame — Application Profile
At 22A, this drive serves pumps, fans, and compressors at the upper end of small-industrial scale, conveyor sections with moderate load, and process agitators requiring more torque than fractional or 1–2 HP applications. The frame size at this current rating typically supports heatsink-through-panel mounting, reducing panel heat load in sealed enclosures — relevant given the drive dissipates several hundred watts at full output.
For SVC mode at this power level, autotune accuracy matters more than at smaller ratings — larger motors have proportionally more torque available, and a poorly-characterized motor model can produce overshoot or instability under dynamic load changes. Run static autotune with accurate nameplate data at minimum; rotating autotune with the load decoupled gives meaningfully better torque control if the application allows it during commissioning.
Commissioning Sequence
- Verify input voltage and wiring before applying power — confirm phase rotation and voltage are within the 380–480V range.
- Enter motor nameplate data (voltage, current, frequency, speed) accurately before any autotune or SVC operation.
- Wire STO inputs (S1, S2, +24V) to the machine's safety relay output before enabling the drive — never jumper them as a shortcut.
- Set a static IP address via the HIM before connecting to the production EtherNet/IP network.
- Run autotune, then test at reduced speed before committing to full-speed operation under load.
FAQ
Q: Does this drive require an input line reactor?
Not mandatory, but recommended on supplies with low source impedance or where multiple drives share a transformer. A 1.5–3% line reactor reduces harmonic distortion and limits transient stress on the rectifier at this current level.
Q: Can the relay output be configured for drive fault indication?
Yes. Configure the relay output function parameter to "Fault" — the relay changes state when the drive trips, providing a hardwired signal to a PLC input or panel indicator independent of the network connection.
Q: What is the purpose of the dual EtherNet/IP ports at this power rating?
Both ports support DLR ring topology, allowing the drive to participate in a ring network without an external switch at its location. For star topology installations, the second port can serve as a local pass-through for a downstream device.
Q: Is a dynamic braking resistor required?
Only if the application produces regenerative energy during deceleration that exceeds the drive's internal capacitor absorption capacity — high-inertia loads or fast deceleration ramps typically require an external resistor connected to the drive's DB terminals
