Allen-Bradley 20F11RC015AA0NNNNN — Detailed Technical Specifications, Product Introduction, Applications, Advantages and Related Models

1. Product Overview

The 20F11RC015AA0NNNNN is an Allen-Bradley PowerFlex 753 AC Drive designed for three-phase industrial motor control applications.

This model is a 400 VAC, 15.4 A, 7.5 kW normal-duty AC drive with a 5.5 kW heavy-duty rating. It is an air-cooled, open-type drive with embedded I/O, EMC filtering, an internal dynamic-braking transistor and a blank/no-HIM configuration.

The model belongs to the PowerFlex 753 family, a drive platform intended for industrial machinery where adjustable motor speed, controlled acceleration, controlled deceleration, motor protection and automation-system integration are required.

A particularly important detail of this exact catalog number is the AA configuration, which uses a removed common-mode capacitor jumper.

The drive is designed for cabinet installation and is especially suitable for applications such as conveyors, pumps, fans, blowers, feeders, packaging machinery, material-handling equipment and general-purpose industrial machinery.

---

2. Product Identification

The 15.4 A output rating is the most important electrical characteristic when selecting this model.

For normal-duty operation, the drive is rated for approximately 7.5 kW / 10 HP.

For heavy-duty applications, the applicable rating is approximately 5.5 kW / 7.5 HP.

---

3. Detailed Electrical Parameters

The 15.4 A normal-duty rating provides a useful amount of capacity for medium-size industrial motors.

The heavy-duty rating drops to 11.5 A because heavy-duty applications normally impose greater thermal and torque demands on the drive.

---

4. Normal-Duty and Heavy-Duty Ratings

This distinction is important when applying the drive to machinery.

A motor that appears to match the drive based only on horsepower may not actually be suitable if its nameplate current exceeds the applicable current rating.

The motor nameplate current, load torque and duty cycle should therefore be checked together.

---

5. What the 20F11RC015AA0NNNNN Does

The simplest way to understand the product is to view it as an electronic controller between the industrial control system and the AC motor.

A typical system looks like this:

PLC / Machine Controller

↓

Control Command

↓

20F11RC015AA0NNNNN

↓

Three-Phase AC Motor

↓

Mechanical Load

The drive receives a speed, start/stop or other control command.

It then regulates the electrical output supplied to the motor.

This allows the motor to run at controlled speeds instead of simply operating at one fixed speed.

The drive can also provide controlled acceleration and deceleration.

That is particularly useful when machines have heavy loads, frequent starting and stopping, or processes that require different operating speeds.

---

6. Product Series — PowerFlex 753

The 20F11RC015AA0NNNNN belongs to the PowerFlex 753 series.

The PowerFlex 753 family is designed for industrial AC motor-control applications.

The series covers multiple motor sizes and voltage classes, allowing machine builders to use a common drive platform across different equipment configurations.

This is useful for companies that manufacture several machines with different motor sizes.

Instead of designing each machine around a completely different drive architecture, the engineer can remain within the same general PowerFlex platform.

This can simplify:

• Electrical drawings
• Cabinet design
• Programming
• Commissioning
• Maintenance
• Spare-parts management
• Technician training
• Troubleshooting

---

7. Brand Information

---

8. 7.5 kW Normal-Duty Capacity

The 7.5 kW normal-duty rating is one of the main reasons to select this model.

It places the drive above the 5.5 kW class while remaining within a relatively compact Frame 1 platform.

The 15.4 A normal-duty current rating provides additional capacity compared with the 11.5 A model.

This can be useful for machines using motors whose nameplate current is above the smaller drive’s rating.

---

9. 5.5 kW Heavy-Duty Capacity

For heavy-duty operation, the drive is rated at approximately 5.5 kW and 11.5 A continuous current.

This can be suitable for applications where the motor experiences greater torque demand.

Typical examples include:

• Material handling
• Loaded conveyors
• Feeders
• Mixers
• Processing equipment
• Machines with high starting torque

The exact application should be evaluated according to the actual motor current and torque requirement.

---

10. 400 VAC Three-Phase Design

The 20F11RC015AA0NNNNN is intended for the 400 VAC three-phase class.

This makes it appropriate for many industrial electrical systems using 380–400 VAC three-phase supplies.

Before installation, the electrical engineer should verify:

• Incoming line voltage
• Number of phases
• Supply frequency
• Motor voltage
• Motor current
• Motor frequency
• Grounding arrangement
• Protective devices
• Short-circuit requirements

The motor must also be suitable for variable-frequency-drive operation.

---

11. Frame 1 Mechanical Design

The drive uses a Frame 1 construction.

This is an important advantage because the drive offers a relatively high 15.4 A normal-duty output without moving into a substantially larger mechanical platform.

Approximate dimensions are:

400.5 mm height × 110 mm width × 211 mm depth

Approximate weight:

6.0 kg

The relatively narrow width is especially useful in compact electrical cabinets.

---

12. Dimensions and Weight

The stated dimensions represent the approximate drive body dimensions.

A control cabinet should provide additional clearance.

Space should be considered for:

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

The approximately 6.0 kg drive weight should also be considered when designing the mounting structure.

---

13. Forced-Air Cooling

The drive uses forced-air cooling to remove heat generated by its power electronics.

This cooling method is well suited to industrial cabinet installations.

However, the drive’s cooling system depends on the surrounding cabinet environment.

A cabinet that is too hot, too dusty or poorly ventilated can negatively affect drive operation.

Good cabinet design should consider:

• Ambient temperature
• Internal cabinet temperature
• Air circulation
• Cooling-fan condition
• Dust
• Heat from neighboring equipment
• Cabinet ventilation

When several drives are installed together, their combined heat generation should be included in the thermal design.

---

14. Open-Type / IP20 Enclosure

The drive uses an open-type IP20 enclosure.

This means the drive is normally installed inside an electrical cabinet or suitable enclosure.

The surrounding cabinet provides additional environmental protection.

This is important in industrial environments where there may be:

• Dust
• Oil mist
• Moisture
• Metal particles
• Chemical vapors
• High humidity
• Temperature fluctuations

The open-type drive should not be considered a sealed outdoor product.

---

15. EMC Filtering

The 20F11RC015AA0NNNNN has an EMC-filtered configuration.

A variable frequency drive uses high-frequency switching to generate controlled motor voltage and frequency.

That switching process can create electrical noise.

The integrated filtering helps reduce certain conducted electromagnetic disturbances.

However, EMC performance depends on the entire installation.

Correct practices include:

• Proper grounding
• Correct motor cable selection
• Cable shielding where required
• Separation of power and signal cables
• Proper cabinet bonding
• Short grounding paths
• Correct routing of control cables

The drive’s EMC filter should therefore be considered one part of the complete EMC design.

---

16. Common-Mode Capacitor Jumper Removed

The AA portion of the catalog number identifies an important configuration.

For 20F11RC015AA0NNNNN, the common-mode capacitor jumper is removed.

This is important when comparing it with the corresponding JA configuration.

The two models are very closely related electrically.

However, the CM capacitor configuration can affect system compatibility and grounding considerations.

Therefore, the complete catalog number should be checked during replacement.

---

17. Dynamic-Braking Transistor

The drive includes an internal dynamic-braking transistor.

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

During motor deceleration, mechanical energy can be returned to the drive’s DC bus.

If this energy is not managed, DC-bus voltage can increase.

A braking resistor can dissipate the excess energy.

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

Typical applications include:

• High-inertia conveyors
• Packaging machinery
• Material handling
• Rapid-cycle machines
• Rotary machinery
• Machines with frequent stopping
• Applications requiring short deceleration times

The external 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 provides a convenient way to connect basic machine-control signals directly to the drive.

Typical functions can include:

• Start
• Stop
• Enable
• Direction
• Speed reference
• Fault reset
• Status indication
• Digital inputs
• Digital outputs
• Analog signals

For simple machines, this can reduce the amount of additional interface equipment required.

For larger automation systems, the drive can be integrated into a PLC-based control architecture.

---

19. Blank / No HIM

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

HIM means Human Interface Module.

A local HIM can be useful for:

• Commissioning
• Parameter adjustment
• Local monitoring
• Fault diagnosis
• Local control

However, many modern machines use a dedicated HMI as the operator interface.

For such equipment, a drive-mounted keypad may not be necessary.

The blank/no-HIM configuration can therefore be a practical choice for OEM machines where the operator controls the system through the machine HMI.

---

20. Main Product Applications

20.1 Conveyor Systems

Conveyors are one of the most common applications for industrial AC drives.

The 20F11RC015AA0NNNNN can provide adjustable conveyor speed.

This can be useful when production lines require different operating speeds.

The drive can also provide controlled acceleration.

Instead of applying full motor torque immediately, the motor can accelerate according to a programmed ramp.

This can reduce mechanical shock on:

• Belts
• Chains
• Gearboxes
• Couplings
• Shafts

---

21. Pump Applications

The drive can be used for suitable industrial pump applications.

Examples include:

• Process-water pumps
• Cooling-water pumps
• Circulation systems
• Fluid-transfer equipment
• Utility pumps

Variable-speed operation allows the pump motor to operate according to process requirements.

For appropriate centrifugal-pump systems, reduced motor speed can also provide opportunities for energy savings.

The actual pump operating point should always be evaluated before selecting the final speed range.

---

22. Fan and Blower Applications

Industrial fans and blowers often need variable airflow rather than constant maximum output.

The drive can change motor speed according to the required process condition.

Typical applications include:

• Factory ventilation
• Exhaust systems
• Cooling fans
• Process-air systems
• Industrial ventilation
• Equipment cooling

This can provide more flexible operation than a simple fixed-speed motor starter.

---

23. Packaging Equipment

Packaging machinery often requires frequent starting, stopping and speed changes.

The drive can provide:

• Adjustable operating speed
• Controlled acceleration
• Controlled deceleration
• Direction control
• Repeatable motor operation
• Dynamic braking capability

A typical machine cycle can be:

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

The controlled motion can help reduce mechanical shock.

---

24. Material-Handling Equipment

Material-handling machinery can place significant demands on motors.

Heavy loads require controlled acceleration to avoid excessive mechanical shock.

The drive can gradually increase motor speed.

This can improve the behavior of:

• Conveyors
• Transfer systems
• Feeders
• Hoists in appropriate configurations
• Material-processing equipment

The actual torque requirements should be checked carefully, especially for applications with high starting torque.

---

25. Feeders

Industrial feeders often need accurate and adjustable speed.

The drive can allow the feed rate to be changed according to production requirements.

Potential applications include:

• Bulk material feeding
• Packaging lines
• Processing machinery
• Assembly equipment
• Product transfer
• Production conveyors

The drive can be controlled through embedded I/O or through the machine’s broader automation architecture.

---

26. Mixers

Mixers can have significant starting torque requirements.

The motor may need to overcome material resistance before reaching normal operating speed.

The drive can provide controlled acceleration.

This can be useful for:

• Industrial mixers
• Processing machinery
• Blending equipment
• Material-handling systems

The correct duty rating should be selected based on the actual mixer torque profile.

---

27. General Industrial Machinery

The drive can be applied to many industrial machines where the motor current remains within the drive’s rating.

Examples include:

• Production machinery
• Conveyors
• Pumps
• Fans
• Blowers
• Feeders
• Processing machines
• Material-transfer systems
• Auxiliary machine drives

---

28. Major Advantages of the 20F11RC015AA0NNNNN

28.1 15.4 A Normal-Duty Current

The 15.4 A continuous normal-duty output is the defining electrical advantage of this model.

It provides more capacity than the 11.5 A version while remaining in the same general compact drive family.

---

28.2 7.5 kW Normal-Duty Rating

The 7.5 kW normal-duty rating makes the drive suitable for many approximately 10 HP-class applications.

This provides a useful step up from 5.5 kW-class PowerFlex 753 models.

---

28.3 5.5 kW Heavy-Duty Rating

The heavy-duty rating provides 5.5 kW capacity for applications with more demanding torque requirements.

---

28.4 Compact Frame 1 Design

The Frame 1 construction is attractive for cabinet applications where space is limited.

---

28.5 400 VAC Compatibility

The drive is designed for the 400 VAC industrial class.

---

28.6 Internal Dynamic-Braking Transistor

The internal DB transistor allows the use of an external braking resistor for suitable applications.

---

28.7 Embedded I/O

Embedded I/O simplifies basic machine integration.

---

28.8 EMC Filtering

The filtered configuration supports EMC-conscious industrial installations.

---

28.9 Blank / No HIM

The blank/no-HIM configuration is convenient for machines controlled primarily through PLC and HMI systems.

---

28.10 PowerFlex 753 Platform

The PowerFlex 753 platform gives machine builders a consistent drive architecture across different motor sizes.

---

29. Advantages for OEM Machine Builders

For machine builders, one of the biggest advantages of the 20F11RC015AA0NNNNN is that it offers 7.5 kW normal-duty capacity in a compact Frame 1 package.

This can help reduce cabinet width.

The 110 mm approximate width can be particularly useful when the cabinet contains several drives and other automation components.

The common PowerFlex 753 platform can also simplify standardization.

An OEM can use related models for smaller or larger motors while retaining a familiar drive architecture.

This can reduce engineering effort over the lifetime of a machine family.

---

30. Advantages for Maintenance

The drive provides useful operating and diagnostic information for maintenance personnel.

Depending on the machine configuration, technicians can monitor:

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

This information can help distinguish between electrical, mechanical and control-system problems.

---

31. Five Recommended Same-Series Models

The following models are closely related PowerFlex 753 configurations that can be considered for applications requiring different motor sizes.

The first four models are particularly useful for comparing current and power capacity within the same 400 VAC family.

The JA version of the 15.4 A drive is especially relevant as a closely related configuration because its main difference is the common-mode capacitor jumper arrangement.

---

32. Same-Series Electrical Comparison

The 15.4 A model is the largest of these five examples in terms of normal-duty current capacity.

---

33. Five Related Models Under the Same Brand

These should be treated as related product choices rather than automatic replacements.

The actual replacement decision should consider voltage, current, motor-control method, I/O, communications, braking, enclosure and physical dimensions.

---

34. Five Popular Allen-Bradley Models

The PowerFlex 525 is generally attractive for compact machine applications.

The PowerFlex 40 is useful where straightforward general-purpose motor control is required.

The PowerFlex 753 is better suited to industrial machinery requiring a broader feature set and a more comprehensive drive platform.

The PowerFlex 755 is a related higher-level option for applications that need additional control and integration capabilities.

---

35. 20F11RC015AA0NNNNN vs. 20F11RC015JA0NNNNN

This is one of the most important comparisons for this model.

The electrical ratings are essentially the same.

The major configuration difference is the common-mode capacitor jumper.

For the AA model, the jumper is removed.

For the JA model, the jumper is installed.

When replacing an existing drive, this detail should be checked carefully.

---

36. 20F11RC015AA0NNNNN vs. 20F11RC011AA0NNNNN

The 20F11RC015AA0NNNNN provides approximately 34% more normal-duty current capacity than the 11.5 A model.

This makes it the better choice when the motor’s actual current requirement is too high for the smaller model.

---

37. 20F11RC015AA0NNNNN vs. 20F11RC8P7AA0NNNNN

The 15.4 A model provides considerably more motor-control capacity.

However, if the motor only requires approximately 8.7 A, the smaller drive may be sufficient depending on the application.

---

38. Conveyor Application Example

A typical conveyor system can use the drive as follows:

PLC

↓

Speed Command

↓

20F11RC015AA0NNNNN

↓

7.5 kW-Class Motor

↓

Gearbox

↓

Conveyor

The PLC can command different conveyor speeds depending on production requirements.

The drive controls motor frequency and voltage to achieve the required speed.

Acceleration can be programmed to prevent sudden mechanical loading.

Deceleration can also be controlled.

If the machine requires rapid stopping, the dynamic-braking system can be considered.

---

39. Pump Application Example

A pump system can use the drive to control flow according to process demand.

A typical arrangement is:

Pressure / Flow Sensor

↓

Controller

↓

PowerFlex 753

↓

Pump Motor

↓

Pump

The controller can increase or decrease the speed command.

This allows the pump to respond to actual process conditions.

For suitable centrifugal pumps, variable-speed operation can provide significant flexibility compared with fixed-speed operation.

---

40. Fan Application Example

An industrial ventilation fan can operate according to temperature or pressure.

For example:

Low Demand → Low Speed

Normal Demand → Medium Speed

High Demand → High Speed

The drive can adjust the motor accordingly.

This provides better control over ventilation and airflow.

---

41. Packaging Application Example

Packaging equipment often requires repetitive motor cycles.

A typical cycle might be:

Start

↓

Acceleration

↓

Production Speed

↓

Deceleration

↓

Stop

↓

Next Cycle

The drive can provide the required acceleration and deceleration profiles.

This can make the mechanical movement smoother and more consistent.

---

42. Material-Handling Application Example

Material-handling equipment frequently involves high inertia or heavy loads.

Starting a heavily loaded conveyor too quickly can place substantial stress on the mechanical transmission.

The drive can provide a controlled acceleration ramp.

This can reduce sudden torque transfer to:

• Belts
• Chains
• Gearboxes
• Couplings
• Shafts

This is one of the practical reasons AC drives are widely used in material-handling machinery.

---

43. Cabinet Design Considerations

The approximate drive dimensions are:

400.5 mm × 110 mm × 211 mm

However, the cabinet should not be designed with only those dimensions in mind.

Additional space is required for:

• Airflow
• Cable routing
• Power terminals
• Control terminals
• Grounding
• Maintenance
• Heat dissipation
• Adjacent equipment

The drive should also be positioned so that heated exhaust air does not directly enter another drive’s cooling inlet.

---

44. Electrical Installation Considerations

Before installing the 20F11RC015AA0NNNNN, check the following.

Incoming Power

Verify that the three-phase supply is compatible with the 400 VAC drive rating.

Motor Current

The motor nameplate current must be within the applicable drive rating.

Motor Voltage

The motor should be appropriate for the drive output voltage.

Motor Duty

Determine whether the application should be treated as normal duty or heavy duty.

Braking

If rapid deceleration is required, calculate the braking energy and determine whether an external braking resistor is necessary.

Grounding

The AA configuration has the CM capacitor jumper removed.

The grounding and system configuration should therefore be evaluated as part of the complete installation.

---

45. Maintenance Recommendations

Routine maintenance should include the drive and its surrounding installation.

Important inspection points include:

• Cooling fan
• Air passages
• Cabinet ventilation
• Dust accumulation
• Power terminals
• Grounding connections
• Motor cable
• Control wiring
• Braking components
• Fault history
• Operating temperature

Cooling is particularly important.

If dust blocks the air passages, the drive can operate at higher temperatures.

Keeping the cabinet clean and maintaining appropriate airflow can help reduce thermal stress.

---

46. Product Advantages Summary

---

47. Recommended Model Selection

The motor nameplate current should always take priority over a simple horsepower comparison.

---

48. Why This Model Is Particularly Useful

The 20F11RC015AA0NNNNN occupies an important position within the PowerFlex 753 family.

The smaller 8.7 A and 11.5 A models are suitable for lower-power motors.

The 15.4 A version provides the next step in capacity.

This makes it useful for machines where the motor current is too high for an 11.5 A drive but does not justify moving to a substantially larger drive.

Its combination of:

• 15.4 A normal-duty current
• 7.5 kW normal-duty capacity
• 11.5 A heavy-duty current
• 5.5 kW heavy-duty capacity
• 400 VAC operation
• Frame 1 construction
• Embedded I/O
• EMC filtering
• Dynamic-braking transistor
• Forced-air cooling

makes it a practical industrial drive for many medium-size motor applications.

---

49. Complete Technical Summary

50. Final Product Assessment

The 20F11RC015AA0NNNNN is a 400 VAC, three-phase PowerFlex 753 AC drive with a 15.4 A normal-duty output rating and 7.5 kW normal-duty capacity.

Its heavy-duty rating is approximately 11.5 A and 5.5 kW, giving the drive useful flexibility between normal-duty and more demanding motor applications.

One of the strongest characteristics of the model is its combination of relatively high electrical capacity and compact Frame 1 construction.

With approximate dimensions of 400.5 mm high × 110 mm wide × 211 mm deep and an approximate weight of 6.0 kg, it can be a practical choice for control cabinets where available panel width is limited.

The drive also provides a useful set of industrial features.

These include 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 is particularly important because the common-mode capacitor jumper is removed.

This should be considered carefully when selecting a replacement or comparing it with the closely related 20F11RC015JA0NNNNN configuration.

For conveyors, pumps, fans, blowers, packaging machines, feeders and material-handling systems, the drive can provide adjustable motor speed and controlled acceleration and deceleration.

For applications with frequent stopping, the integrated dynamic-braking transistor can also provide useful braking flexibility when paired with an appropriately selected external braking resistor.

For OEM machine builders, the PowerFlex 753 platform offers another important advantage: the ability to maintain a consistent drive family across different motor sizes.

The 20F11RC011AA0NNNNN can be used for lower-current applications, while the 20F11RC015AA0NNNNN provides additional capacity for motors requiring up to approximately 15.4 A under normal-duty conditions.

For applications requiring approximately 7.5 kW normal-duty motor control in a 400 VAC three-phase system, the 20F11RC015AA0NNNNN is therefore a strong and practical member of the PowerFlex 753 family.

In short, the model can be described as a 15.4 A, 7.5 kW normal-duty, 11.5 A, 5.5 kW heavy-duty, 400 VAC, three-phase, Frame 1 PowerFlex 753 AC drive with embedded I/O, forced-air cooling, EMC filtering, removed common-mode capacitor jumper, internal dynamic-braking transistor, AC input with precharge, DC terminals and blank/no-HIM configuration.

Its combination of motor-control capacity, compact construction, industrial functionality and flexible integration makes it well suited to a wide range of automated industrial machinery.
