The Allen Bradley 25A-D017N104 PowerFlex 523 AC Drive is a compact variable-frequency drive from the PowerFlex 523 family, used for controlling AC motors in machine automation and industrial equipment. It is intended for applications where motor operation needs to be adjusted according to the production process, machine cycle, or mechanical load.
In a typical installation, the drive sits between the incoming electrical system and the motor, while a PLC, operator interface, or other controller supplies the operating commands. This makes it possible to coordinate motor behavior with the rest of the machine instead of treating the motor as an independent on/off device.

The 25A-D017N104 manages the operating condition of a connected AC motor by controlling the electrical output supplied to the motor. The desired operating condition can originate from the machine controller, operator controls, or another external command source.
For a material-handling machine, for example, the motor may need to run at one speed while transporting a product and reduce speed during positioning. The drive allows these changes to be incorporated into the machine’s operating sequence.
A simplified system arrangement is:
Control System → 25A-D017N104 → AC Motor → Driven Equipment
The controller determines the required machine action, while the drive handles the motor-control portion of that action.
| Application | Typical Use |
|---|---|
| Conveyor Equipment | Adjusting transportation speed |
| Packaging Machinery | Coordinating motor speed with machine cycles |
| Pump Systems | Changing motor operation according to process demand |
| Fan Equipment | Regulating motor-driven airflow |
| Material Handling | Controlling movement speed |
| Assembly Machinery | Synchronizing motor-driven mechanisms |
| Production Lines | Adjusting motor operation during different process stages |
| General Automation | Variable-speed AC motor control |
| Component | Function |
|---|---|
| PLC / Controller | Controls the machine sequence |
| AC Motor | Produces mechanical output |
| Operator Interface | Provides operator commands and status information |
| Sensors | Detect process and machine conditions |
| Circuit Protection | Protects the incoming electrical circuit |
| Motor Protection | Protects the motor circuit |
| Motor Cable | Connects the drive output to the motor |
| Control Wiring | Carries external operating signals |
The appropriate component combination depends on the machine architecture, motor requirements, electrical supply, and control strategy.
With dimensions of 109 × 220 × 184 mm, the 25A-D017N104 is suitable for applications where cabinet space is an important consideration. Even so, the installation should provide enough room for power and motor wiring, ventilation, inspection, and maintenance access.
Before commissioning, the complete catalog number should be checked against the intended application. Incoming power, motor connections, grounding, control wiring, and protective devices should be inspected before energizing the system.
During the initial run, technicians should verify motor rotation and observe the response to operating commands. If unexpected motor behavior or a drive fault occurs, the motor, wiring, control signals, and surrounding equipment should be checked before determining whether the drive itself is defective.
| Model | Product Series | Primary Function |
|---|---|---|
| Allen Bradley 25A-D017N104 | PowerFlex 523 | AC motor speed control |
| Allen Bradley 25A-D017N114 | PowerFlex 523 | Variable-speed AC motor control |
| Allen Bradley 25A-D013N104 | PowerFlex 523 | Compact AC motor control |
| Allen Bradley 25A-D013N114 | PowerFlex 523 | Variable-speed motor applications |
| Allen Bradley 25A-D010N114 | PowerFlex 523 | AC motor-speed control |
| Allen Bradley 25A-D024N104 | PowerFlex 523 | Larger PowerFlex 523 configuration |
Although these models belong to the same PowerFlex family, the complete catalog number and electrical configuration should be verified before considering one as a replacement for another.
The 25A-D017N104 combines a compact physical format with the variable-speed functionality required by many automated machines. This makes it useful where the available control-panel space is limited but the motor still needs to respond to changing operating commands.
Its role within a machine can also simplify coordination between motor operation and the production sequence. Instead of using separate fixed-speed switching arrangements for different operating conditions, the drive becomes part of the machine’s overall motor-control strategy.
The 25A-D017N104 is used to control the operating speed and operation of an AC motor within industrial machinery and automated equipment.
The drive can be incorporated into a wider control system, allowing motor operation to respond to commands from a PLC or other machine-control equipment.
Yes. The stated dimensions should be compared with the available cabinet space, while also allowing room for electrical connections, ventilation, and maintenance.
The complete catalog number, motor requirements, electrical supply, control arrangement, wiring, and application should be verified before installation. Physical dimensions alone cannot establish compatibility.
