Allen-Bradley 20F11RC011AA0NNNNN — Detailed Product Specifications, Product Introduction, Applications, Advantages and Related Models

1. Product Overview

The 20F11RC011AA0NNNNN is an Allen-Bradley PowerFlex 753 AC Drive designed for industrial variable-speed control of three-phase AC motors.

This model is a 400 VAC, three-phase, Frame 1 drive with an 11.5 A continuous output rating. It is rated at approximately 5.5 kW for normal-duty operation and 4.0 kW for heavy-duty operation.

The drive features embedded I/O, forced-air cooling, AC input with precharge and DC terminals, an open-type IP20/IP00 enclosure, EMC filtering, a removed common-mode capacitor jumper, an internal dynamic-braking transistor and a blank/no-HIM configuration.

The AA configuration is important because the common-mode capacitor jumper is removed. This is one of the configuration details that distinguishes this model from the closely related JA version.

The 20F11RC011AA0NNNNN is designed for industrial machines that need controlled motor speed rather than simple fixed-speed operation. Typical applications include conveyors, pumps, fans, blowers, material-handling equipment, packaging machinery and other general industrial machines.

---

5. Product Series — PowerFlex 753

The 20F11RC011AA0NNNNN belongs to the PowerFlex 753 series.

PowerFlex 753 is an industrial AC drive platform designed for machinery and automation applications where adjustable motor speed, controlled acceleration, controlled deceleration and system integration are required.

The series is available in a broad range of voltage, current and power configurations.

This makes it possible for an equipment manufacturer to use a common drive family across different machine sizes.

For example, a smaller machine can use a lower-current PowerFlex 753 model, while a larger machine can use a higher-current model without changing the overall drive-family concept.

This can simplify:

• Electrical engineering
• Cabinet design
• Machine programming
• Spare-parts management
• Maintenance training
• Troubleshooting
• Equipment standardization

---

6. Brand Information

---

7. Product Introduction

The 20F11RC011AA0NNNNN is essentially a programmable electronic motor controller.

A traditional motor starter generally provides simple functions such as starting and stopping a motor.

A variable frequency drive provides much greater control.

The drive can regulate the electrical frequency and voltage supplied to the motor, allowing the motor to operate at different speeds.

A typical control structure is:

PLC / Controller → Drive → AC Motor → Mechanical Load

The PLC or machine controller determines what the machine needs to do.

The drive receives the command and generates the appropriate electrical output for the motor.

This allows a machine to accelerate smoothly, operate at a controlled speed and decelerate according to programmed requirements.

---

8. 11.5 A Output Rating

One of the most important specifications of the 20F11RC011AA0NNNNN is its 11.5 A continuous normal-duty output current.

The drive is rated for approximately:

5.5 kW normal duty

and

4.0 kW heavy duty

The approximate motor horsepower equivalents are:

7.5 HP normal duty

and

5 HP heavy duty.

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

Horsepower alone is not sufficient for final drive selection because different motors can have different current requirements.

---

9. Normal-Duty and Heavy-Duty Ratings

The normal-duty rating is appropriate for applications where the motor does not continuously experience severe overload conditions.

Heavy-duty operation is intended for applications with greater torque demand or more demanding acceleration and load characteristics.

The short-term current values should not be treated as continuous ratings.

---

10. 400 VAC Three-Phase Operation

The drive is designed for the 400 VAC three-phase class.

This makes it suitable for industrial electrical systems commonly based around 380–400 VAC three-phase supplies.

The incoming power system should be checked before installation.

Important parameters include:

• Supply voltage
• Supply phase
• Supply frequency
• Motor voltage
• Motor current
• Motor frequency
• Grounding arrangement
• Protective devices

The motor should also be suitable for operation from a variable frequency drive.

---

11. Frame 1 Construction

The 20F11RC011AA0NNNNN uses a Frame 1 construction.

Frame 1 is one of the smaller mechanical platforms in the PowerFlex 753 family.

This is useful because the drive provides substantial electrical capacity while remaining relatively compact.

The approximate open-type dimensions are:

400.5 mm high × 110 mm wide × 211 mm deep

The approximate weight is:

6.0 kg

This makes the unit practical for industrial control cabinets where panel space is limited.

---

12. Dimensions and Weight

The dimensions are the approximate physical dimensions of the standard open-type Frame 1 drive.

When designing a cabinet, additional space should be allowed around the drive.

The cabinet layout should provide enough room for:

• Power wiring
• Control wiring
• Grounding
• Cable bending
• Ventilation
• Maintenance
• Terminal access
• Cooling airflow
• Adjacent components

---

13. Air-Cooled Design

The drive uses forced-air cooling.

Power electronic components generate heat during operation.

The cooling system removes this heat and helps maintain the electronics within their appropriate operating temperature range.

Good cabinet ventilation is therefore important.

The installation should take into account:

• Ambient temperature
• Cabinet temperature
• Airflow
• Cooling fan operation
• Dust
• Heat from neighboring equipment
• Cabinet ventilation
• Required clearances

When several drives are installed together, the combined heat generated by all equipment should be considered.

---

14. Open-Type Enclosure

The 20F11RC011AA0NNNNN uses an open-type enclosure.

This means the drive normally needs to be installed inside an appropriate electrical cabinet or enclosure.

The external cabinet provides the environmental protection required by the installation.

This is especially important where the machine is exposed to:

• Dust
• Oil mist
• Water
• Chemical vapors
• Metal particles
• High humidity
• Excessive temperature

The open-type drive should not be treated as a sealed standalone field enclosure.

---

15. EMC Filtering

The model has an EMC-filtered configuration.

Variable frequency drives use high-frequency semiconductor switching.

This switching is necessary for motor control, but it can also produce electrical noise.

The integrated filtering helps control certain conducted electromagnetic disturbances.

However, good EMC performance also depends on the complete installation.

Important practices include:

• Proper grounding
• Correct cable routing
• Suitable motor cable
• Appropriate shielding
• Short grounding connections
• Separation of power and control wiring
• Proper cabinet bonding

The EMC filter is therefore one component of the overall electromagnetic compatibility design.

---

16. Common-Mode Capacitor Jumper Removed

The AA configuration of this model has the common-mode capacitor jumper removed.

This is a particularly important detail when comparing the AA and JA versions.

The two versions are otherwise very closely related in their basic electrical characteristics.

However, this configuration difference can matter in grounding-sensitive applications and replacement work.

Therefore, the exact catalog number should be checked before replacing one configuration with another.

---

17. Dynamic Braking

The 20F11RC011AA0NNNNN includes an internal dynamic-braking transistor.

Dynamic braking is useful when the motor needs to decelerate rapidly.

When a motor slows down, it can return energy to the drive’s DC bus.

This can cause the DC bus voltage to rise.

A suitable external braking resistor can dissipate this excess energy.

The internal transistor provides the switching function required to control the braking resistor.

Typical applications include:

• High-inertia conveyors
• Material handling
• Packaging machines
• Rapid-cycle equipment
• Rotary machinery
• Machines with frequent stops
• Machines requiring shorter deceleration times

The actual braking resistor must be selected according to the machine’s braking energy and duty cycle.

---

18. Embedded I/O

The drive includes embedded I/O.

This allows many basic machine-control functions to be connected directly to the drive.

Typical functions can include:

• Start
• Stop
• Enable
• Direction
• Speed reference
• Fault reset
• Run status
• Digital inputs
• Digital outputs
• Analog signals

For relatively simple machines, embedded I/O can reduce the number of external interface devices required.

For larger automation systems, the drive can be combined with PLCs, HMIs and industrial communications.

---

19. Blank / No HIM

The model has a blank / no-HIM configuration.

HIM stands for Human Interface Module.

A local HIM is useful for:

• Parameter adjustment
• Fault viewing
• Drive monitoring
• Local control
• Diagnostic work

However, many OEM machines use a PLC and HMI as the primary operator interface.

In these applications, a local keypad on the drive may not be necessary.

The blank/no-HIM configuration can therefore be a practical choice for automated machinery.

---

20. Product Applications

20.1 Conveyor Systems

Conveyor systems are a natural application for this type of AC drive.

A conveyor motor may need to run at different speeds depending on the production process.

The drive can provide:

• Adjustable speed
• Smooth starting
• Controlled acceleration
• Controlled deceleration
• Direction control
• Fault handling
• PLC integration

Instead of starting the motor at full speed, the drive can accelerate it gradually.

This can reduce mechanical shock.

---

21. Pump Applications

The 20F11RC011AA0NNNNN can be used for suitable industrial pump applications.

Typical examples include:

• Process-water pumps
• Circulation pumps
• Cooling pumps
• Fluid-transfer systems
• Industrial utility pumps

A variable-speed pump can operate according to process demand.

For suitable centrifugal-pump applications, reducing speed can also reduce energy consumption.

The pump curve and required system pressure should always be considered when determining the operating speed range.

---

22. Fan and Blower Applications

Fans and blowers often do not need to run continuously at maximum speed.

A variable frequency drive can adjust the motor speed according to airflow requirements.

Typical applications include:

• Industrial ventilation
• Exhaust systems
• Equipment cooling
• Process air
• Factory ventilation
• Air-handling equipment

The drive can therefore provide better process flexibility than a simple fixed-speed motor starter.

---

23. Packaging Machinery

Packaging equipment often requires repetitive motor operation.

A typical sequence might be:

Start → Accelerate → Production Speed → Decelerate → Stop → Repeat

The drive can control the acceleration and deceleration profile.

This can make machine operation smoother.

It can also help reduce mechanical shock during frequent starts and stops.

Typical applications include:

• Packaging conveyors
• Feeders
• Product transfer
• Material handling
• Film-handling equipment
• Auxiliary machinery

---

24. Material-Handling Applications

Material-handling systems can benefit from controlled motor acceleration.

Sudden acceleration can place significant stress on mechanical components.

Controlled acceleration can reduce shock transmitted to:

• Belts
• Chains
• Gearboxes
• Couplings
• Shafts
• Mechanical frames

This can be particularly useful for conveyors and feeders.

---

25. Fan and Ventilation Systems

Industrial ventilation equipment often benefits from adjustable-speed operation.

The drive can allow a fan motor to operate at different speeds depending on:

• Temperature
• Pressure
• Airflow
• Production conditions
• Equipment requirements

This provides more flexible operation than a simple contactor-controlled motor.

---

26. General Industrial Machinery

The drive can also be used for general-purpose industrial machinery where the motor and load fall within the rated electrical range.

Potential applications include:

• Feeders
• Processing equipment
• Small production machines
• Auxiliary rotating machinery
• Conveyors
• Fans
• Pumps
• Blowers
• Material-transfer equipment

---

27. Advantages of the 20F11RC011AA0NNNNN

27.1 High Current Capacity in a Compact Frame

The drive provides 11.5 A continuous normal-duty output in a Frame 1 package.

This gives it a useful combination of electrical capacity and compact mechanical size.

---

27.2 5.5 kW Normal-Duty Rating

The 5.5 kW normal-duty rating makes the drive suitable for many medium-size industrial motors.

It is substantially more powerful than the smaller 2.1 A, 3.5 A, 5.0 A and 8.7 A configurations within the same 400 VAC family.

---

27.3 4.0 kW Heavy-Duty Rating

For more demanding applications, the 4.0 kW heavy-duty rating provides useful overload capability.

The application should be evaluated according to the actual torque and duty requirements.

---

27.4 400 VAC Three-Phase Compatibility

The drive is designed for the 380–400 VAC industrial voltage class.

This makes it useful in many international industrial electrical systems.

---

27.5 Dynamic-Braking Transistor

The internal DB transistor provides flexibility for applications requiring rapid deceleration.

An external braking resistor can be used when the application requires additional braking capability.

---

27.6 Embedded I/O

Embedded I/O can simplify basic machine integration.

This can reduce the need for additional interface hardware.

---

27.7 EMC Filtering

The filtered configuration helps support electromagnetic compatibility in industrial installations.

---

27.8 Compact Frame 1 Construction

The approximately 110 mm width is particularly attractive for control cabinets where panel space is limited.

This can be important when multiple drives and control components need to fit into one enclosure.

---

28. Advantages for OEM Machine Builders

For OEMs, a compact drive with substantial current capacity can help reduce cabinet size.

The approximately 110 mm width makes the Frame 1 version particularly attractive for installations where cabinet width is limited.

The PowerFlex 753 family also provides a common platform for different machine sizes.

An OEM can select a smaller or larger drive while maintaining a familiar product family.

This can simplify:

• Electrical drawings
• Cabinet engineering
• Machine programming
• Spare-parts management
• Maintenance procedures
• Technician training

---

29. Advantages for Maintenance Teams

Maintenance teams benefit from the drive’s programmable operation and diagnostic capabilities.

Depending on the machine configuration, technicians can monitor information such as:

• Motor current
• Output frequency
• Drive status
• Fault status
• Speed reference
• Operating state
• Acceleration settings
• Deceleration settings

This can help maintenance personnel identify whether a problem is electrical, mechanical or related to machine programming.

---

30. Five Recommended Same-Series Models

The following models are closely related PowerFlex 753 configurations in the same 400 VAC class.

These models are useful for comparing different motor sizes within the same general PowerFlex 753 family.

The 20F11RC011AA0NNNNN occupies a useful position in the group because it provides 11.5 A normal-duty output while remaining in the compact Frame 1 platform.

---

31. Same-Series Electrical Comparison

The table illustrates the logical progression of current capacity within the 400 VAC PowerFlex 753 family.

---

32. Five Related Models Under the Same Brand

The following models are useful related choices from the broader Allen-Bradley drive portfolio.

These products should be regarded as related alternatives rather than automatic drop-in replacements.

Voltage, current, enclosure, I/O, braking, mounting and control requirements should all be checked before substitution.

---

33. Five Popular Allen-Bradley Models for Comparison

The PowerFlex 525 family is generally attractive for compact machinery.

The PowerFlex 40 family is a useful general-purpose alternative for simpler motor-control applications.

The PowerFlex 753 provides a more substantial industrial drive platform.

The PowerFlex 755 is positioned for applications where more advanced drive capabilities are required.

---

34. 20F11RC011AA0NNNNN vs. 20F11RC011JA0NNNNN

This is the most important closely related comparison.

The electrical ratings are essentially the same.

The most important configuration distinction is the common-mode capacitor jumper.

The AA model has the jumper removed, while the JA model has it installed.

This difference should be considered when replacing an existing drive.

---

35. 20F11RC011AA0NNNNN vs. 20F11RC8P7AA0NNNNN

The 20F11RC8P7AA0NNNNN provides a lower normal-duty current rating.

If the motor requires approximately 11.5 A under normal-duty conditions, the 20F11RC011AA0NNNNN is the more appropriate selection.

---

36. 20F11RC011AA0NNNNN vs. 20F11RC015AA0NNNNN

The 15.4 A model provides additional capacity but uses the larger Frame 2 construction.

This is important for cabinet planning.

---

37. Conveyor Application Example

Consider a conveyor powered by a 5.5 kW three-phase motor.

A simple motor starter would normally provide only start and stop control.

With the 20F11RC011AA0NNNNN, the conveyor can be programmed to accelerate gradually.

For example:

Start

↓

Low-Speed Acceleration

↓

Production Speed

↓

Controlled Deceleration

↓

Stop

This can reduce mechanical shock and provide better control of the production process.

If the conveyor needs multiple speeds, the drive can receive different speed commands from the machine controller.

---

38. Pump Application Example

Consider an industrial pump that does not need to operate at full speed continuously.

Instead of operating the motor at one fixed speed, the controller can adjust the drive’s speed reference.

For example:

Low Process Demand → Low Motor Speed

Normal Process Demand → Medium Motor Speed

High Process Demand → Higher Motor Speed

This can improve process control and may reduce energy consumption in suitable pump applications.

---

39. Fan Application Example

An industrial ventilation fan can also benefit from variable-speed operation.

A temperature or pressure sensor can provide information to the controller.

The controller can then adjust the drive speed.

For example:

Low Temperature → Lower Fan Speed

Normal Temperature → Medium Fan Speed

High Temperature → Higher Fan Speed

This allows the ventilation system to respond to actual process requirements.

---

40. Packaging Application Example

A packaging machine may require a motor to accelerate and decelerate repeatedly.

The drive can provide a programmed acceleration profile.

This can make the machine’s operation smoother and more repeatable.

The dynamic-braking transistor can also be useful when the application requires controlled stopping.

The final braking resistor selection should be based on actual machine inertia and stopping-cycle requirements.

---

41. Material-Handling Application Example

Material-handling equipment often benefits from controlled acceleration because sudden starts can create mechanical stress.

A conveyor carrying heavy material can place substantial load on:

• Gearboxes
• Chains
• Belts
• Couplings
• Shafts

The drive allows acceleration to be programmed rather than simply applying full power immediately.

This can improve machine behavior and reduce unnecessary mechanical shock.

---

42. Installation Recommendations

Electrical Supply

Use a compatible three-phase 400 VAC-class power supply.

Motor

Verify:

• Motor voltage
• Motor current
• Motor frequency
• Motor power
• Motor duty
• Motor connection

Mechanical Load

Important maintenance points include:

• Cooling fan
• Air passages
• Cabinet ventilation
• Dust accumulation
• Power terminals

45. Model Selection Guide

This table should be used as a general selection guide.

For an actual installation, the motor nameplate current is more important than horsepower alone.

---

46. Important Points Before Replacement

When replacing an existing 20F11RC011AA0NNNNN, the following should be checked carefully.

Voltage

The replacement should be compatible with the existing 400 VAC three-phase system.

Current

The replacement should provide sufficient continuous current for the motor.

48. Final Product Assessment

The 20F11RC011AA0NNNNN is a compact but capable PowerFlex 753 AC drive designed for 400 VAC three-phase industrial motor applications.

Its 11.5 A normal-duty continuous output and 5.5 kW normal-duty rating make it suitable for approximately 7.5 HP-class motors, while its 8.7 A heavy-duty rating and 4.0 kW heavy-duty capacity make it useful for more demanding applications in the approximately 5 HP range.

One of the strongest features of this model is the combination of relatively high output capacity with a Frame 1 mechanical design.

At approximately 400.5 mm high, 110 mm wide and 211 mm deep, the drive is relatively narrow compared with many larger industrial drives.

Its approximate weight of 6.0 kg also makes it manageable for control-cabinet installation.

The drive provides a useful combination of industrial features, including embedded I/O, forced-air cooling, EMC filtering, AC input with precharge, DC terminals, an internal dynamic-braking transistor and a blank/no-HIM configuration.

The AA configuration with the common-mode capacitor jumper removed is particularly important for system compatibility and replacement work.

The drive is well suited to machinery where controlled motor speed is required.

Conveyors can benefit from smooth acceleration and adjustable production speed.

Pumps can benefit from variable-speed operation according to process demand.

Fans and blowers can operate at different speeds depending on airflow requirements.

Packaging equipment can use controlled acceleration and deceleration for repetitive machine cycles.

Material-handling systems can use controlled starting and stopping to reduce mechanical shock.

For machine builders, another important advantage is the broader PowerFlex 753 family.

The same general drive platform is available at different current and power levels, allowing an equipment manufacturer to standardize the control architecture while selecting different drive sizes for different motors.

For applications requiring less capacity, the 20F11RC5P0AA0NNNNN or 20F11RC8P7AA0NNNNN can be considered.

For higher-capacity applications, the 20F11RC015AA0NNNNN provides a higher current rating and moves to the larger Frame 2 platform.

The closely related 20F11RC011JA0NNNNN has essentially the same main electrical rating but uses the installed common-mode capacitor jumper configuration, so the AA and JA versions should not be treated as identical catalog configurations.

Overall, the 20F11RC011AA0NNNNN can be described as a 400 VAC, three-phase, Frame 1 PowerFlex 753 industrial AC drive with 11.5 A normal-duty output, 8.7 A heavy-duty output, 5.5 kW normal-duty capacity, 4.0 kW heavy-duty capacity, embedded I/O, forced-air cooling, EMC filtering, removed common-mode capacitor jumper, internal dynamic-braking transistor, AC input with precharge, DC terminals and a blank/no-HIM configuration.

It is particularly attractive for industrial machinery that needs a combination of compact cabinet dimensions, relatively high motor-control capacity, programmable speed control, braking capability and integration with an automated control system.
