Allen-Bradley 20F11NE1P7AA0NNNNN — Detailed Product Specifications, Introduction, Applications, Advantages and Recommended Models

1. Product Overview

The Allen-Bradley 20F11NE1P7AA0NNNNN is a compact industrial AC variable frequency drive from the PowerFlex 753 series.

It is a 600 VAC, three-phase, air-cooled AC drive with a 1.7 A normal-duty output rating and a 0.9 A heavy-duty continuous-current rating. Its corresponding motor ratings are approximately 1 HP for normal-duty operation and 0.5 HP for heavy-duty operation.

The drive is configured with embedded I/O, AC input with precharge, DC bus terminals, an EMC filter, an internal dynamic-braking transistor, an open-type enclosure, and no HIM operator keypad.

One particularly important detail of this catalog number is the AA configuration, which means the common-mode capacitor jumper is removed. This makes it different from a closely related JA configuration even though the basic voltage, current and horsepower ratings can be similar.

The model uses Frame 3 construction. Despite its relatively small motor rating, it belongs to the same PowerFlex 753 architecture used for substantially larger industrial drives.

This makes it useful when a project requires the functionality and architecture of the PowerFlex 753 family but only needs a relatively small motor capacity.

---

2. Brand and Product Series

The PowerFlex 753 family covers a broad range of industrial motor sizes. The 1.7 A model is positioned toward the smaller end of the 600 VAC range, while larger models in the same family extend into substantially higher current and horsepower ratings.

---

3. Detailed Technical Parameter Table

The most important electrical figures are 1.7 A normal-duty and 0.9 A heavy-duty.

The normal-duty motor rating is approximately 1 HP, while the heavy-duty rating is approximately 0.5 HP.

The drive’s overload figures are also worth noting because variable-frequency drives are not normally selected solely according to the motor’s horsepower.

---

4. Output Current and Duty Ratings

The drive has two different continuous-current ratings.

This distinction is important.

A relatively light-duty application such as a small fan may be evaluated against the normal-duty rating.

A machine with greater torque demand, more difficult acceleration or more frequent overload conditions may need to be evaluated using the heavy-duty rating.

The motor’s nameplate current should always be checked before making the final selection.

---

5. Product Model Number Explanation

The catalog number 20F11NE1P7AA0NNNNN contains several configuration identifiers.

The 1P7 section is the most obvious electrical identifier because it represents the 1.7 A current class.

The AA configuration is also significant because it indicates that the common-mode capacitor jumper is removed.

This should be checked carefully when comparing this model with related models or when replacing an existing drive.

---

6. Product Introduction

The 20F11NE1P7AA0NNNNN is designed to control small three-phase AC motors in industrial environments.

Although the motor capacity is relatively small, the drive belongs to a much larger industrial drive platform.

This is useful when a machine has multiple motors and the designer wants to keep a consistent drive architecture across the machine.

Instead of using one completely different drive platform for every motor size, a designer can use smaller and larger PowerFlex 753 configurations where appropriate.

The drive provides adjustable motor speed rather than simply switching the motor between on and off states.

That allows the motor to accelerate gradually, operate at a controlled speed and decelerate according to the requirements of the machine.

This is particularly useful for equipment where sudden starting or stopping could create mechanical problems.

---

7. What Makes This Model Different?

The most interesting characteristic of the 20F11NE1P7AA0NNNNN is that it combines a small motor rating with a relatively sophisticated industrial drive architecture.

A 1 HP motor does not necessarily require a large industrial drive platform.

However, in a machine containing many motors, standardizing the control architecture can be more important than choosing the smallest possible drive.

For example, a machine may have:

• One 0.5 HP auxiliary motor.
• One 1 HP conveyor motor.
• Several larger process motors.

If the larger motors are already using PowerFlex 753 drives, using a PowerFlex 753 configuration for a smaller motor can provide a consistent engineering and maintenance environment.

That can be valuable in larger machine-building projects.

---

8. Main Electrical Features

8.1 600 VAC Three-Phase Input

The drive belongs to the 600 VAC three-phase PowerFlex 753 range.

This is a significant point because the voltage class is considerably higher than the voltage used by many small general-purpose drives.

The motor and electrical distribution system must therefore be compatible with the 600 VAC class.

A lower-voltage drive should not be substituted simply because its horsepower rating is similar.

---

8.2 1.7 A Normal-Duty Output

The normal-duty continuous output rating is 1.7 A.

This corresponds to approximately 1 HP.

The model is therefore suitable for small motors where the operating current remains within the applicable 1.7 A rating.

Typical applications can include:

• Small conveyors.
• Small fans.
• Small pumps.
• Auxiliary machinery.
• Small material-handling mechanisms.
• Small process motors.

---

8.3 0.9 A Heavy-Duty Rating

The heavy-duty continuous rating is approximately 0.9 A.

This corresponds to approximately 0.5 HP.

The heavy-duty rating should be considered when the machine requires greater overload performance or more demanding starting and operating conditions.

A small motor with high starting torque requirements may need to be evaluated under this rating rather than simply using the 1 HP normal-duty figure.

---

9. Dynamic Braking

The 20F11NE1P7AA0NNNNN includes an internal dynamic-braking transistor.

Dynamic braking is useful when the motor needs to decelerate more quickly than it could through normal uncontrolled coast-down.

When the motor decelerates, mechanical energy can return to the drive’s DC bus.

The braking circuit can direct this energy into an external braking resistor when required.

The internal braking transistor is therefore a useful built-in feature.

However, the drive does not mean that a complete internal braking resistor is installed.

Where significant braking energy is involved, an appropriately sized external resistor must be considered.

For small motors, the braking requirements are usually modest, but applications involving frequent starts and stops can still benefit from careful braking analysis.

---

10. EMC Filtering

The drive includes an EMC filter.

Electromagnetic compatibility can be important in industrial control cabinets because variable-frequency drives use high-speed electronic switching.

The filtering arrangement helps manage electrical noise and can be useful where the drive is installed near:

• PLC systems.
• Sensors.
• Instrumentation.
• Communication equipment.
• Measurement devices.
• Other electronic controllers.

The exact installation arrangement should still take into account grounding, cable routing and motor-cable characteristics.

---

11. CM Capacitor Jumper Removed

One of the specific configuration details of 20F11NE1P7AA0NNNNN is the removed CM capacitor jumper.

This is represented by the AA portion of the catalog number.

A closely related configuration using JA has the jumper installed.

The difference may look minor from the outside, but it can be relevant to the electrical grounding and common-mode behavior of the installation.

When replacing an existing drive, the catalog number should therefore be compared carefully rather than assuming that all models with the same voltage and current are electrically identical.

---

12. Embedded I/O

The PowerFlex 753 platform includes embedded I/O.

For a small machine, this can be useful because basic control signals can be handled directly by the drive rather than requiring a large number of additional interface components.

Possible signals can include:

• Start.
• Stop.
• Enable.
• Forward.
• Reverse.
• Speed reference.
• Fault reset.
• Status.
• Interlock.
• Process-control signals.

The exact I/O configuration depends on the application and the overall control architecture.

---

13. No HIM Configuration

The model is supplied with a blank / no HIM configuration.

HIM means Human Interface Module.

A HIM normally provides a local display and keypad for:

• Parameter adjustment.
• Drive status monitoring.
• Fault display.
• Local control.
• Commissioning.

The absence of a HIM can actually be useful in a machine where the drive is controlled centrally through a PLC or other automation system.

It also keeps the front of the drive relatively simple.

If local operator access is required, an appropriate external interface can be added according to the system design.

---

14. Frame 3 Construction

The drive uses Frame 3 construction.

Frame size is important because it affects the physical dimensions, mounting arrangement, weight and cabinet design.

For this model, the approximate physical dimensions are:

454 mm high × 190 mm wide × 212 mm deep

or approximately:

45.4 cm high × 19.0 cm wide × 21.2 cm deep

The approximate product weight is:

11.80 kg

For cabinet design and transportation planning, approximately 12 kg is a practical allowance.

---

15. Dimensions and Weight

The 212 mm depth is relatively compact compared with larger PowerFlex 753 configurations.

However, cabinet depth should not be designed solely around the drive’s physical depth.

Additional space may be required for:

• Incoming cables.
• Motor cables.
• Grounding.
• Control wiring.
• Communication wiring.
• Cable bending radius.
• Cooling airflow.
• Maintenance access.

---

16. Typical Applications

16.1 Small Conveyor Systems

The drive can be used for small conveyor motors where adjustable speed is required.

Variable-speed control can make the conveyor easier to integrate into a production line.

Possible benefits include:

• Smooth starting.
• Controlled stopping.
• Adjustable conveyor speed.
• Reduced mechanical shock.
• Better synchronization with other equipment.

For a small conveyor, the 1 HP normal-duty rating may be appropriate if the motor current remains within the drive’s limits.

---

16.2 Small Pumps

Small industrial pumps can benefit from adjustable-speed operation.

The drive can allow the motor speed to be adjusted according to process demand.

Potential applications include:

• Circulation pumps.
• Small process pumps.
• Cooling-water pumps.
• Fluid-transfer systems.
• Auxiliary pumping equipment.

Pump type should be considered when determining whether the normal-duty or heavy-duty rating is appropriate.

---

16.3 Small Fans

Small fans and blowers are another natural application.

Fan speed can be adjusted according to airflow requirements.

This can provide:

• Better airflow control.
• Smoother starting.
• Reduced mechanical stress.
• Potential energy savings.

The 1 HP normal-duty rating makes the model suitable for a range of small fan applications.

---

16.4 Auxiliary Motors

One of the strongest reasons to use a PowerFlex 753 at this size is architectural consistency.

The motor may be a relatively small auxiliary motor on a much larger machine.

Examples include:

• Auxiliary cooling fans.
• Small feeders.
• Small pumps.
• Auxiliary conveyors.
• Material positioning mechanisms.
• Small extraction fans.
• Machine-support equipment.

Using the same general drive family across the machine can simplify maintenance and commissioning.

---

16.5 Small Material-Handling Systems

Material-handling equipment often benefits from controlled speed.

The drive can be used for:

• Small transfer mechanisms.
• Feeders.
• Small conveyors.
• Positioning systems.
• Packaging machinery.
• Small sorting mechanisms.

The appropriate current rating should be selected based on the actual motor nameplate current and machine duty.

---

17. Product Advantages

17.1 Industrial 600 VAC Capability

The 600 VAC rating makes this model different from many compact low-voltage drives.

It is designed for industrial electrical systems where the motor and distribution system operate at this voltage class.

---

17.2 Small Motor Rating with PowerFlex 753 Architecture

This is perhaps the most interesting advantage.

The model allows a small motor to participate in the same general drive architecture as larger PowerFlex 753-controlled motors.

This can be helpful for machine builders who want to standardize their drive platform.

---

17.3 Integrated EMC Filter

The EMC filter is built into the drive configuration.

This can simplify the overall electrical design and help address electromagnetic compatibility requirements.

---

17.4 Dynamic Braking Transistor

The internal DB transistor is a useful feature for applications that require controlled deceleration.

It reduces the need for a completely separate braking-control device.

---

17.5 Embedded I/O

Embedded I/O allows basic machine signals to be handled directly by the drive.

This can simplify control-panel wiring.

---

17.6 Compact Frame 3 Design

Although the model is part of an industrial drive family, its Frame 3 enclosure is relatively compact compared with larger PowerFlex 753 frames.

Its approximate size is only:

454 × 190 × 212 mm

This makes it practical for cabinet installation where space is limited.

---

18. Five Recommended Models from the Same PowerFlex 753 Series

The following models are useful alternatives within the same 600 VAC PowerFlex 753 range.

| Model | Series | Voltage | Normal-duty current | Heavy-duty current | Normal-duty HP | Heavy-duty HP | Frame |
|—|—|—:|—:|—:|—:|—:|
| 20F11NE2P7AA0NNNNN | PowerFlex 753 | 600 VAC | 2.7 A | 1.7 A | 2 HP | 1 HP | 3 |
| 20F11NE3P9AA0NNNNN | PowerFlex 753 | 600 VAC | 3.9 A | 2.7 A | 3 HP | 2 HP | 3 |
| 20F11NE6P1AA0NNNNN | PowerFlex 753 | 600 VAC | 6.1 A | 3.9 A | 5 HP | 3 HP | 3 |
| 20F11NE9P0AA0NNNNN | PowerFlex 753 | 600 VAC | 9.0 A | 6.1 A | 7.5 HP | 5 HP | 3 |
| 20F11NE011AA0NNNNN | PowerFlex 753 | 600 VAC | 11 A | 9 A | 10 HP | 7.5 HP | 3 |

These models provide a useful progression from approximately 2 HP through 10 HP while retaining the same general 600 VAC PowerFlex 753 architecture.

The 20F11NE2P7AA0NNNNN is the most natural step upward from the 1.7 A model.

The 20F11NE6P1AA0NNNNN is a useful middle-range choice for approximately 5 HP normal-duty applications.

The 20F11NE011AA0NNNNN is appropriate when substantially more current is required but the application can still use a Frame 3 PowerFlex 753 configuration.

---

19. Same-Series Comparison Table

The main benefit of this group is that the drive capacity can be increased while maintaining the same basic series and voltage class.

---

20. Five Related Popular Models Under the Same Brand

When the application does not specifically require a PowerFlex 753 drive, other Allen-Bradley drive families can also be considered.

The following are representative PowerFlex 525 models for general-purpose industrial applications.

These models are related alternatives rather than direct electrical replacements for the 20F11NE1P7AA0NNNNN.

The most obvious difference is voltage.

The 20F11NE1P7AA0NNNNN belongs to the 600 VAC PowerFlex 753 range, while the listed PowerFlex 525 examples are generally associated with the 480 VAC class.

Therefore, the two groups should not be exchanged without checking the actual motor and electrical system.

---

21. PowerFlex 753 Versus PowerFlex 525

For a small 1 HP motor, a compact general-purpose drive may appear more economical from a purely physical standpoint.

However, if the machine already uses PowerFlex 753 drives for other motors, the 20F11NE1P7AA0NNNNN can make sense because it keeps the same general drive architecture.

---

22. Recommended Applications by Model

---

23. Cabinet Installation

The drive uses an open-type enclosure, so it is normally installed inside a suitable electrical cabinet or control enclosure.

The cabinet should protect the drive from excessive contamination and provide adequate airflow.

For this model, the basic physical envelope is approximately:

454 mm × 190 mm × 212 mm

However, the cabinet should not be designed with only these three numbers.

Additional space should be allowed for:

• Power connections.
• Motor connections.
• Grounding.
• Control wiring.
• Communication wiring.
• Air circulation.
• Maintenance.
• Cable bending.
• Component clearance.

A well-designed cabinet should allow technicians to work around the drive without having to remove unrelated equipment.

---

24. Weight and Handling

The approximate weight of the 20F11NE1P7AA0NNNNN is 11.80 kg.

For practical engineering purposes, allowing approximately 12 kg is reasonable.

The drive is substantially lighter than the larger Frame 5 PowerFlex 753 models, but it is still heavy enough that proper mounting is important.

The mounting plate should be rigid enough to support the drive without excessive vibration.

This becomes especially important when the drive is installed on mobile machinery or equipment subject to mechanical vibration.

---

25. Why 600 VAC Matters

The 600 VAC rating is one of the defining characteristics of this product.

Many compact industrial drives are designed around 200–240 VAC or 380–480 VAC systems.

The 20F11NE1P7AA0NNNNN belongs to a different voltage class.

This makes it particularly useful for industrial installations where:

• The electrical distribution is 600 VAC.
• The motor is rated for 600 VAC.
• Other drives on the machine use the same voltage class.
• A common electrical architecture is required.

The motor voltage, supply voltage and drive voltage must always be checked together.

---

26. Maintenance Advantages

One practical advantage of using the same PowerFlex 753 platform across a machine is maintenance standardization.

If an industrial plant uses several PowerFlex 753 drives, technicians can become familiar with the same general:

• Parameter structure.
• Fault handling.
• Control philosophy.
• Commissioning procedures.
• I/O concepts.
• Drive status information.
• Communication architecture.

The 1.7 A model can therefore function as part of a larger standardized drive system rather than being viewed only as an isolated 1 HP drive.

---

27. Advantages for Machine Builders

Machine builders may benefit from using this model when a machine already relies heavily on the PowerFlex 753 platform.

For example, a production machine may contain:

• A 1 HP auxiliary motor.
• A 5 HP conveyor.
• A 10 HP fan.
• A 20 HP process motor.
• A larger main motor.

Using different drive families for every motor can make the machine more complicated to support.

A standardized PowerFlex 753 architecture can simplify the engineering process.

The same general platform can then be scaled according to motor current.

---

28. Advantages for Spare-Parts Management

Standardization can also help with spare-parts management.

A facility using many different drive families may need technicians to maintain knowledge of many different interfaces and parameter structures.

A facility that uses a consistent drive platform can reduce some of that complexity.

The 20F11NE1P7AA0NNNNN is therefore potentially valuable as a small-motor drive when consistency with larger PowerFlex 753 equipment is important.

---

29. Product Strengths at a Glance

---

30. Important Selection Considerations

Motor Current

The motor’s actual nameplate current should be checked before selecting the drive.

A motor rated at 1 HP does not automatically have the same current requirement as every other 1 HP motor.

Voltage, efficiency, power factor and motor design all influence current.

---

Duty Cycle

The difference between normal-duty and heavy-duty ratings must be considered.

For this model:

Normal Duty: 1.7 A / 1 HP

Heavy Duty: 0.9 A / 0.5 HP

Using the wrong duty rating can result in an undersized drive.

---

Voltage

The drive is a 600 VAC-class model.

The incoming electrical supply must be compatible with this rating.

---

Braking

If the machine requires rapid stopping, dynamic-braking requirements should be calculated.

The internal transistor is available, but the braking resistor itself is not necessarily included.

---

Cabinet Environment

The drive is open type.

It should therefore be installed inside an appropriate enclosure with suitable environmental protection.

---

31. 20F11NE1P7AA0NNNNN vs. 20F11NE2P7AA0NNNNN

These two models are natural neighbors within the same family.

The 2.7 A version is the logical choice when the 1.7 A current rating is insufficient.

---

32. 20F11NE1P7AA0NNNNN vs. 20F11NE3P9AA0NNNNN

The 3.9 A model provides more than twice the normal-duty continuous current capacity of the 1.7 A version.

34. Overall Product Assessment

35. Final Recommendation

The Allen-Bradley 20F11NE1P7AA0NNNNN is a 600 VAC, three-phase PowerFlex 753 AC drive designed for approximately 1 HP normal-duty or 0.5 HP heavy-duty motor applications.

Its electrical specification is relatively small compared with many other PowerFlex 753 models, but that does not make it a basic or limited-purpose controller.

Its value comes from combining a small motor rating with the broader PowerFlex 753 industrial drive architecture.

The drive includes embedded I/O, an EMC filter, an internal dynamic-braking transistor, AC input with precharge, DC terminals, Frame 3 construction and a no-HIM configuration.

The approximate physical dimensions are 454 × 190 × 212 mm, while the approximate weight is 11.80 kg.

For engineering and cabinet planning, it is sensible to allow approximately 12 kg for the drive itself and additional cabinet space for wiring, ventilation and service access.

For applications requiring slightly more capacity, the 20F11NE2P7AA0NNNNN is a natural next step.

For approximately 3 HP applications, the 20F11NE3P9AA0NNNNN becomes more appropriate.

For 5 HP, 7.5 HP and 10 HP applications, the 20F11NE6P1AA0NNNNN, 20F11NE9P0AA0NNNNN and 20F11NE011AA0NNNNN provide a convenient progression within the same 600 VAC family.

For applications where a smaller and more compact general-purpose drive is preferred, other PowerFlex families may be worth considering, but voltage, current, control architecture and environmental requirements must be checked before making a substitution.

Overall, the 20F11NE1P7AA0NNNNN is best suited to small industrial three-phase motors where a 600 VAC supply is required and where maintaining a PowerFlex 753-based control architecture is valuable.

Its strongest advantages are not simply its 1 HP rating, but the combination of 600 VAC capability, industrial construction, embedded I/O, EMC filtering, dynamic-braking capability, expandable architecture and compatibility with a broader family of PowerFlex 753 drives.

For a machine containing several motors of different sizes, this model can be particularly useful as the small-motor member of a standardized drive architecture.
