Product Overview
Allen-Bradley 25A-D4P0N104 and 25A-D6P0N104 are PowerFlex 523 AC drives that regulate three-phase motor output from a 380…480 V three-phase source. 25A-D4P0N104 provides 4.0 A for 1.5 kW (2 HP), while 25A-D6P0N104 provides 6.0 A for 2.2 kW (3 HP).
In 25A-D4P0N104 and 25A-D6P0N104, R/L1, S/L2 and T/L3 feed the input stage, U/T1, V/T2 and W/T3 connect to the motor, and the protective-earth terminal joins the supply and motor grounding path. Reversing any two motor phase leads changes the commanded forward direction.
The command circuit of 25A-D4P0N104 and 25A-D6P0N104 keeps stop, programmable digital inputs, analog reference and RS-485 DSI communication electrically distinct. Terminal assignments and parameter selections determine which signal starts the drive, which signal establishes speed and how the motor stops.

System Integration
25A-D4P0N104 and 25A-D6P0N104 connect the three-phase supply, motor circuit and protective-earth path through separate terminal groups.
Motor connection
U/T1, V/T2 and W/T3 deliver the controlled three-phase output to the motor windings.
Ground continuity
The drive and motor protective-earth conductors connect to the marked PE points independently of signal common.
Operating Characteristics
The run behavior of 25A-D4P0N104 and 25A-D6P0N104 depends on the selected stop method, reference source and digital-input assignments.
Stop response
Terminal 01 always acts as the stop input, and the stop-mode parameter determines the resulting deceleration or coast behavior.
Acceleration profile
Configured acceleration and deceleration times control how quickly output frequency changes after a command.
Reference tracking
The drive follows the selected keypad, analog, preset or DSI speed reference within its configured limits.
Frequently Asked Questions
What separates the ratings of 25A-D4P0N104 / 25A-D6P0N104?
25A-D4P0N104 is rated 4.0 A and 25A-D6P0N104 is rated 6.0 A. Both remain in Frame A.
How can motor direction be reversed on 25A-D4P0N104 / 25A-D6P0N104?
Interchange any two motor phase leads at U/T1, V/T2 and W/T3. Perform the wiring change only after isolation and voltage verification.
Can a digital input select acceleration behavior on 25A-D4P0N104 / 25A-D6P0N104?
A programmable digital terminal can be assigned to a supported command function. Its parameter assignment and electrical wiring must describe the same input logic.
Where is protective earth connected for 25A-D4P0N104 / 25A-D6P0N104?
Use the marked safety-ground terminal for the equipment grounding conductor. Keep that path continuous through the supply and motor circuits.
Does the stop input remain active after other inputs are reassigned on 25A-D4P0N104 / 25A-D6P0N104?
Yes. Terminal 01 retains its stop function while other digital terminals can receive programmable assignments.
What sequence is required for an output contactor used with 25A-D4P0N104 / 25A-D6P0N104?
Disable drive output before the contactor opens or closes. Re-enable output only after the contactor has reached its commanded state.
