Product Description
The Allen-Bradley 25B-D1P4N104 is a PowerFlex 525 AC drive for 380…480 V AC, three-phase input. It provides a 1.4 A output and a 0.4 kW (0.5 HP) motor rating in both normal-duty and heavy-duty service, all within the compact Frame A construction.
Local operation on 25B-D1P4N104 is handled through an integral keypad, speed potentiometer and LED display. The drive also includes an embedded EtherNet/IP interface, allowing its network identity to be established through the embedded adapter without adding a separate communication module.
The 25B-D1P4N104 enclosure is IP20 NEMA / Open Type, with a brake IGBT included and no integral EMC filter. Its exact catalog configuration carries a model-specific mounting restriction: horizontal mounting is not permitted, so the mounting orientation and temperature derating remain part of the enclosure layout.

Network setup
Embedded EtherNet/IP Commissioning
The embedded adapter in 25B-D1P4N104 supports direct network commissioning while keeping address ownership and grounding explicit.
Unique node identity
Every device on the EtherNet/IP network requires a unique IP address before normal communication can be established.
Applying a manual change
A manually entered IP address becomes active after the drive or embedded adapter is reset or power is cycled.
Shield reference
Control terminal C1 is tied internally to the RJ45 shield and is connected to clean ground for the documented star-topology arrangement.
Safety boundary
Safe-Torque-Off Operating Boundary
The Safe-Torque-Off circuit in 25B-D1P4N104 interrupts the gate-control path to the output IGBTs; it does not remove all hazardous voltage from the drive.
Dual-channel state
Both S1 and S2 are energized for operation. Removing either channel disables output gate control.
Safety capability
The integrated function supports applications up to Category 3 / Performance Level d and SIL 2 when the complete safety system meets the required design.
Reaction and motion
The specified safety reaction time is no more than 100 ms, and STO by itself initiates a coast-to-stop response.
Electrical isolation
Input power must still be disconnected and zero energy verified before electrical work because STO is not a mains-isolation device.
Frequently Asked Questions
Does 25B-D1P4N104 include an integral EMC filter?
No. The N104 configuration is listed without an integral EMC filter. Check the complete suffix instead of inferring the filter arrangement from the PowerFlex 525 family name.
Can 25B-D1P4N104 be installed horizontally?
Horizontal mounting is not permitted for this catalog number. Review the allowed orientation and temperature derating before finalizing the enclosure layout.
What should be checked before starting 25B-D1P4N104?
Before applying power, confirm the supply, motor, protective device, grounding and control-terminal wiring. The stop input and every safety-circuit connection must match the selected control scheme because an open stop path prevents normal operation.
What do STO discrepancy faults mean on 25B-D1P4N104?
Fault F059 or F111 can indicate that the two Safe-Torque-Off channels did not reach the expected states within the permitted timing. Trace both S1 and S2 circuits and correct the mismatch before resetting the fault.
How is the embedded EtherNet/IP address set on 25B-D1P4N104?
For the embedded adapter, use BOOTP for server-assigned addressing or enter a manual address through the adapter parameters. Give every network node a unique address, then reset the adapter or cycle power after changing a manual address.
Does 25B-D1P4N104 define branch protection and grounding by itself?
No single drive selection defines the complete installation. Match the branch-circuit protection, conductor sizing and grounding path to the supply system and the applicable installation requirements.
