Allen-Bradley 20F11NE022AA0NNNNN — PowerFlex 753 AC Drive

Detailed Product Specifications, Introduction, Applications, Advantages and Related Models

The 20F11NE022AA0NNNNN is a PowerFlex 753 AC Drive designed for three-phase industrial motor control in the 600 VAC class.

It has a 22 A normal-duty output rating, corresponding to approximately 20 HP / 15 kW, and a 17 A heavy-duty rating, corresponding to approximately 15 HP / 11 kW. The unit uses Frame 3 construction and an air-cooled, open-type industrial design.

The configuration includes embedded I/O, an EMC filter, an internal dynamic-braking transistor, AC input with precharge and DC terminals, and a blank/no-HIM configuration. The AA configuration also uses the CM capacitor jumper removed arrangement.

For applications requiring a higher-capacity drive than the 17 A version, this 22 A model provides a useful step up while remaining within the same Frame 3 PowerFlex 753 family.

---

1. Product Basic Information

The published product description identifies this configuration as a 600 VAC, three-phase, 22 A, 20 HP normal-duty, 15 HP heavy-duty, Frame 3 PowerFlex 753 drive with embedded I/O, EMC filtering, dynamic braking and no HIM.

---

2. Brand and Product Series

The product hierarchy can be expressed as:

Allen-Bradley → PowerFlex → PowerFlex 753 → 20F11NE022AA0NNNNN

The PowerFlex 753 family is intended for industrial applications where adjustable motor speed, integrated control functions and flexible automation-system integration are required.

---

3. Product Introduction

The 20F11NE022AA0NNNNN is an industrial variable-frequency drive designed to control three-phase AC motors.

A variable-frequency drive changes the frequency and voltage supplied to the motor, allowing the motor to operate at different speeds instead of running continuously at one fixed line frequency.

This makes the drive useful in machinery where motor speed needs to follow the production process.

A conveyor, for example, may need to operate at several different speeds during loading, transportation and unloading.

A pump may need to increase or reduce its speed according to pressure or flow requirements.

A fan may operate at reduced speed when the required airflow is lower.

A mixer may require different speeds during different stages of a process.

The drive provides the electrical and control functions required to manage these operating conditions.

---

4. Main Electrical Ratings

The most important electrical ratings are shown below.

The PowerFlex 753 rating table lists 22 A normal-duty / 17 A heavy-duty, with 20 HP normal-duty / 15 HP heavy-duty for this exact model.

This dual-rating concept is important when selecting the drive.

A machine with a relatively stable load may be evaluated against the 20 HP normal-duty rating.

A machine with higher overload requirements should instead be evaluated against the 15 HP heavy-duty rating.

---

5. Detailed Technical Parameters

The catalog data confirms that the 22 A model is a Frame 3 600 V drive; the next 600 V model, 27 A, moves to Frame 4, making the 22 A model the upper end of this particular Frame 3 section.

---

6. 600 VAC Three-Phase Configuration

The 600 VAC three-phase configuration is one of the defining characteristics of this drive.

This makes the model suitable for industrial facilities using higher-voltage three-phase motor systems.

The voltage class should be checked before selecting a drive.

For example, a 20 HP motor cannot be matched to a drive based only on its horsepower rating.

The motor voltage, motor current, electrical distribution system and drive voltage class all need to be compatible.

---

7. 22 A Normal-Duty Rating

The model provides 22 A continuous output current under the normal-duty rating.

The corresponding motor rating is approximately:

20 HP / 15 kW

This places the model in a useful medium-power industrial range.

It is large enough for many applications involving:

• Conveyors
• Pumps
• Fans
• Blowers
• Mixers
• Material-handling equipment
• Packaging machinery
• Industrial processing equipment
• Production-line machinery

---

8. 17 A Heavy-Duty Rating

The heavy-duty rating is:

17 A / 15 HP / approximately 11 kW

This rating is particularly important when the machine experiences higher mechanical loads.

Examples include:

• High starting torque
• High inertia
• Repeated acceleration
• Repeated deceleration
• Frequent speed changes
• Intermittent overload
• Heavy material loads

The motor’s actual nameplate current should always be compared against the applicable drive rating.

---

9. Overload Capability

The 20F11NE022AA0NNNNN provides different short-term current levels depending on the duty classification.

These ratings are useful when evaluating machines that have temporary load increases.

The overload rating should not be interpreted as permission to operate continuously above the continuous-current rating.

The actual acceleration profile, load inertia, motor characteristics and operating cycle need to be considered during application engineering.

---

10. Frame 3 Construction

The 20F11NE022AA0NNNNN uses Frame 3 construction.

This is important because frame size affects:

• Physical dimensions
• Mounting
• Cooling
• Terminal arrangement
• Cabinet layout
• Power capacity
• Service access

The 22 A model is particularly useful because it provides a relatively high current rating while remaining within the Frame 3 portion of the 600 V PowerFlex 753 range.

The next 600 V model, 20F11NE027AA0NNNNN, uses Frame 4 construction.

---

11. Dimensions

The approximate physical dimensions are:

A dimensional listing for this exact catalog number gives approximately 23.86 in × 14.25 in × 13.62 in, corresponding to roughly 60.6 × 36.2 × 34.6 cm.

When installing the drive, additional cabinet space is required for cable routing, cooling airflow and maintenance access.

The dimensions of the drive itself should therefore not be treated as the complete cabinet-space requirement.

---

12. Weight

The approximate product weight is:

11.6 kg

Weight should be considered during:

• Cabinet mounting
• Panel construction
• Shipping
• Maintenance
• Drive replacement
• Mechanical support design

The actual shipping weight may be greater than the equipment weight because of packaging and accessories.

---

13. Air-Cooled Construction

The drive uses forced-air cooling.

The power section generates heat during normal operation, and the internal cooling system transfers that heat away from the electronic components.

Proper cabinet ventilation is therefore important.

Particular attention should be paid to:

• Airflow
• Ambient temperature
• Cabinet temperature
• Fan operation
• Clearance
• Heat from neighboring components
• Multiple drives installed in one cabinet

If several drives are installed together, the total heat generated inside the cabinet should be evaluated.

---

14. Open-Type IP20 Design

The product is an Open Type / IP20 drive.

It is designed to be installed inside a suitable industrial control cabinet or electrical enclosure.

The drive should not be treated as a weatherproof outdoor standalone enclosure.

The surrounding cabinet should provide appropriate protection against:

• Dust
• Water
• Oil
• Mechanical impact
• Industrial contaminants
• Accidental contact

The required cabinet protection depends on the final installation environment.

---

15. Embedded I/O

The PowerFlex 753 platform includes embedded I/O.

This allows the drive to interact with the machine control system without requiring separate interface hardware for every basic control function.

Typical signals can include:

• Run command
• Stop command
• Enable
• Fault status
• Running status
• Speed reference
• Analog signals
• Digital signals
• Process feedback

This is particularly useful in industrial machinery where the drive is connected to a PLC or other automation controller.

---

16. Dynamic Braking

The model includes an internal dynamic-braking transistor.

Dynamic braking becomes important when a motor needs to slow down quickly.

When a motor decelerates, mechanical energy can be converted into electrical energy and returned to the drive’s DC bus.

If the energy is excessive, the DC-bus voltage can rise.

A dynamic-braking circuit allows the regenerated energy to be transferred to an external resistor.

The resistor dissipates the energy as heat.

This is particularly useful for:

• Conveyors
• High-inertia machinery
• Material handling
• Packaging machines
• Rotating equipment
• Certain machine tools
• Equipment requiring controlled stopping

The braking transistor is part of the drive configuration, while the braking resistor is selected separately according to the application.

---

17. EMC Filtering

The model uses an EMC-filtered configuration.

The drive’s high-frequency switching operation can produce electrical noise.

An EMC filter helps control this interference.

However, the filter is only one part of a complete EMC design.

Correct installation remains important.

Good practices include:

• Proper grounding
• Correct cable shielding
• Suitable motor cable
• Separation of control and power cables
• Proper cabinet bonding
• Appropriate cable routing
• Avoidance of unnecessary cable loops

---

18. CM Capacitor Configuration

The AA configuration uses the CM jumper removed arrangement.

This is an important detail when replacing the drive.

The common-mode capacitor configuration can affect:

• Ground leakage current
• Common-mode behavior
• EMC performance
• Grounding characteristics
• Compatibility with the electrical system

A replacement drive should therefore be checked by its complete catalog number rather than simply matching its horsepower.

---

19. AC Input with Precharge

The drive uses an AC input configuration with precharge and DC terminals.

The precharge circuit controls the initial charging of the DC-bus capacitors.

This is important because the DC bus contains substantial capacitive energy storage.

Controlled precharging reduces the electrical stress that would otherwise occur during initial energization.

---

20. No HIM Configuration

The model uses a Blank / No HIM configuration.

A Human Interface Module is not included as part of the standard configuration.

This is useful when the machine is operated through:

• PLC
• HMI
• SCADA
• Remote operator station
• Industrial network
• Central control system

For automated production equipment, there may be no need for a dedicated keypad mounted directly on each drive.

---

21. PID and Process Control

The PowerFlex 753 platform can be used for process-control applications where motor speed needs to respond to a feedback signal.

PID-type control is useful for applications such as:

• Pump pressure control
• Fan pressure control
• Flow regulation
• Process control
• Air-handling systems

For example, a pump can automatically adjust its speed based on a pressure signal.

This allows the motor to respond to process requirements instead of operating continuously at one fixed speed.

---

22. Application: Conveyor Systems

The 20F11NE022AA0NNNNN is a good fit for medium-sized industrial conveyors.

Conveyor systems often require:

• Variable speed
• Smooth acceleration
• Controlled deceleration
• Adjustable production rate
• Motor overload protection
• Controlled stopping

The 22 A current capacity gives the model more room than the smaller 11 A and 17 A versions.

Dynamic braking can also be valuable when the conveyor carries significant moving mass.

---

23. Application: Pumps

Industrial pumps are another common application.

The drive can regulate motor speed according to process demand.

Typical applications include:

• Cooling-water systems
• Process pumps
• Transfer pumps
• Circulation systems
• Industrial fluid handling
• Water treatment
• Pressure-controlled pumping

Variable-speed operation can be useful when the process does not require maximum pump speed all the time.

---

24. Application: Fans and Blowers

The drive can control fans and blowers in industrial ventilation systems.

Typical applications include:

• Factory exhaust
• Process ventilation
• Cooling equipment
• Industrial air handling
• Dust collection systems
• Blower systems

The motor can run at the speed required by the process rather than remaining at full speed continuously.

---

25. Application: Packaging Equipment

Packaging machinery often requires accurate speed control.

The drive can be used for:

• Feed conveyors
• Rollers
• Product transfer
• Material handling
• Packaging lines
• Auxiliary machinery

Controlled acceleration and deceleration can reduce mechanical shock and improve overall machine behavior.

---

26. Application: Material Handling

Material-handling equipment is another strong application area.

The drive can be used for:

• Transfer conveyors
• Roller systems
• Feeders
• Material positioning
• Production-line transport
• Industrial handling systems

Where the load has significant inertia, the dynamic-braking function can provide additional flexibility during deceleration.

---

27. Application: Mixers and Agitators

Industrial mixers may require different speeds during different stages of production.

The drive allows motor speed to be adjusted according to:

• Material viscosity
• Mixing stage
• Process requirements
• Production rate
• Load conditions

The actual motor torque requirement should be evaluated before selecting the final drive rating.

---

28. Application: Industrial Processing Machinery

The model can also be applied to general industrial processing equipment.

Potential applications include:

• Rotating machinery
• Process lines
• Production equipment
• Industrial machinery
• Auxiliary drives
• Material-processing equipment
• General-purpose motor-driven machines

Its 20 HP normal-duty capacity provides enough room for a substantial range of medium industrial equipment.

---

29. Main Product Advantages

29.1 22 A Output Capacity

The 22 A normal-duty rating is the main electrical advantage of this model.

It provides a 20 HP normal-duty rating, making it suitable for applications that are too large for the 11 A or 17 A versions.

---

29.2 20 HP Normal-Duty Rating

The 20 HP capacity is useful for a wide range of medium industrial machinery.

It provides a good balance between drive capacity and physical size.

---

29.3 15 HP Heavy-Duty Rating

The 15 HP heavy-duty rating gives the drive additional flexibility for applications with higher overload requirements.

This makes it useful for machines where acceleration and transient load conditions are more demanding.

---

29.4 600 VAC Industrial Compatibility

The 600 VAC configuration allows the drive to be used in industrial facilities with higher-voltage three-phase motor systems.

---

29.5 Internal Dynamic-Braking Transistor

Correct grounding and cable practices remain necessary.

---

29.8 Flexible Industrial Control

The PowerFlex 753 architecture supports a wide range of industrial control requirements.

It can be integrated into larger automation systems and used with additional communication or feedback functions when required.

---

30. Five Recommended Models from the Same Series

The following models are closely related PowerFlex 753 configurations.

The 600 V PowerFlex 753 rating progression confirms the 9 A, 11 A, 17 A, 22 A and 27 A configurations and their corresponding normal-duty and heavy-duty horsepower ratings.

The 20F11NE022AA0NNNNN is therefore positioned directly above the 17 A / 15 HP model and below the 27 A / 25 HP model.

---

31. Same-Series Capacity Comparison

The 22 A model is an especially useful step when the motor has moved beyond the 15 HP normal-duty class.

---

32. Five Related Popular Models from the Same Brand

These should be treated as related models rather than direct drop-in replacements.

The electrical voltage, current, frame, options and control architecture must be checked before substituting one model for another.

---

33. PowerFlex 753 vs. PowerFlex 525

The PowerFlex 525 is more attractive when the machine is smaller and cabinet space is limited.

The PowerFlex 753 is better suited to higher-capacity industrial machines and 600 V systems.

---

34. PowerFlex 753 vs. PowerFlex 755

For a 20 HP-class motor, the PowerFlex 753 provides a practical balance of size, capability and cost.

The PowerFlex 755 becomes more attractive when a machine requires more advanced feedback, communication, scalability or higher power.

---

35. Recommended Applications by Load Type

---

36. Motor Selection Guidelines

The motor should not be selected by horsepower alone.

The following information should be checked.

For final engineering selection, the motor nameplate current is generally more useful than horsepower alone.

---

37. Cabinet Design Considerations

The approximate drive body dimensions are:

362 × 346 × 606 mm

This is a substantial piece of equipment and should be given adequate cabinet space.

The cabinet should allow room for:

• Input cables
• Output motor cables
• Control wiring
• I/O wiring
• Grounding
• Communication cables
• Cooling airflow
• Heat dissipation
• Maintenance
• Terminal access
• Braking connections
• Drive removal

The depth of approximately 606 mm is particularly important.

A cabinet that looks sufficiently large from the front may still be too shallow once motor cables, power terminals and wiring bend radius are considered.

---

38. Cooling and Thermal Management

Because the drive uses forced-air cooling, the cabinet designer should provide an appropriate airflow path.

Heat from the drive should not simply accumulate inside the enclosure.

The installation should consider:

• Cabinet ambient temperature
• Heat generated by other drives
• Fan airflow
• Air filters
• Ventilation openings
• Cabinet cooling systems
• Spacing between drives

When multiple variable-frequency drives are installed together, total heat generation should be considered rather than evaluating each drive independently.

---

39. Environmental Considerations

The drive is intended for a suitable industrial environment.

Typical operating conditions include approximately:

0–50 °C

Typical storage conditions are approximately:

−40 to +70 °C

Relative humidity is approximately:

5–95%, non-condensing

The drive should be protected from direct exposure to water, excessive dust and aggressive industrial contaminants.

Condensation should also be avoided.

---

40. Advantages for Machine Builders

The 20F11NE022AA0NNNNN is attractive for machine builders because it provides relatively high motor capacity without moving immediately into the larger Frame 4 class.

The 22 A / 20 HP normal-duty rating covers many medium industrial machines.

The integrated I/O can simplify machine wiring.

The dynamic-braking transistor is useful for controlled stopping.

The no-HIM configuration is convenient for machines that already use an external HMI or PLC.

The 600 V configuration also makes it suitable for higher-voltage industrial machine designs.

---

41. Advantages for System Integrators

For system integrators, the drive offers a flexible foundation for industrial motor control.

It can be integrated into control architectures involving:

• PLCs
• HMIs
• Industrial networks
• Analog references
• Digital control
• Process feedback
• PID functions
• Drive status monitoring

This makes it suitable for both standalone machines and larger automated production lines.

---

42. Advantages for Maintenance

The complete catalog number contains important configuration information.

When replacing an existing drive, technicians should compare:

• Voltage class
• Output current
• Duty rating
• Frame
• EMC configuration
• CM jumper configuration
• Braking configuration
• HIM configuration
• I/O
• Communication options
• Feedback options
• Dimensions

This prevents the common mistake of selecting a replacement based only on horsepower.

---

43. Selection by Motor Size

This shows where the target model fits within the 600 V PowerFlex 753 range.

It is essentially the 20 HP normal-duty / 15 HP heavy-duty point in the progression.

---

44. Key Specifications at a Glance

---

45. Overall Product Assessment

The 20F11NE022AA0NNNNN is a higher-capacity member of the 600 VAC PowerFlex 753 range.

Its 22 A normal-duty rating and 20 HP / 15 kW normal-duty capacity make it suitable for a broad range of medium industrial machines.

For heavy-duty applications, the applicable rating is approximately 17 A / 15 HP / 11 kW.

This makes the model particularly useful for applications where the 10 HP or 15 HP PowerFlex 753 versions are no longer large enough, but a Frame 4 drive is not yet necessary.

One of the notable advantages of this model is that it remains within Frame 3 construction while providing a 22 A output rating.

The next 600 V model in the series, the 27 A version, moves to Frame 4.

The drive is well suited to conveyors, pumps, fans, blowers, packaging equipment, material-handling systems, mixers, agitators and general industrial processing machinery.

The integrated I/O makes machine integration easier, while the dynamic-braking transistor is useful for applications requiring controlled deceleration.

The EMC filter and CM configuration are also important for industrial electrical installations.

The no-HIM configuration makes the drive particularly suitable for PLC-controlled machines and centralized operator-control systems.

From a physical perspective, the drive is approximately 362 × 346 × 606 mm and approximately 11.6 kg, so cabinet depth and cooling should be considered carefully during system design.

The 22 A model is also a useful reference point when selecting related drives.

For smaller 600 V motors, the 11 A and 17 A models may be sufficient.

For approximately 20 HP normal-duty applications, the 20F11NE022AA0NNNNN is a natural fit.

For approximately 25 HP normal-duty applications, the 27 A model provides the next step in capacity.

For compact 480 VAC machinery, a PowerFlex 525-class drive may be more appropriate.

For larger and more sophisticated industrial systems, the PowerFlex 755 family provides additional scalability and advanced control capabilities.

Overall, the 20F11NE022AA0NNNNN can be described as a 600 VAC, 22 A, Frame 3 industrial AC variable-frequency drive with 20 HP normal-duty and 15 HP heavy-duty capability.

Its combination of higher current capacity, 600 V compatibility, embedded I/O, dynamic braking, EMC filtering, flexible control and industrial construction makes it a practical choice for medium-power automated machinery and industrial motor-control systems.
