Allen-Bradley 20F11RD011AA0NNNNN — PowerFlex 753 AC Drive Detailed Product Specifications, Introduction, Applications, Advantages and Related Models

The Allen-Bradley 20F11RD011AA0NNNNN is a PowerFlex 753 AC Drive designed for three-phase industrial motor-speed control.

This model is a 480 VAC class, 3-phase, 11 A Frame 1 AC drive, rated at approximately 7.5 HP / 5.5 kW for Normal-Duty operation and 5 HP / approximately 4.0 kW for Heavy-Duty operation in its Frame 1 configuration.

The drive includes embedded I/O, forced-air cooling, IP20 open-type construction, an EMC filter, CM jumper removed, a dynamic-braking transistor, AC input with precharge, DC terminals, and a blank/no-HIM configuration.

It is particularly well suited to conveyors, feeders, pumps, fans, blowers, material-handling machinery, packaging equipment and general industrial machines where adjustable motor speed, controlled acceleration and deceleration, machine integration and cabinet-based installation are required.

---

1. Product Identification

The exact catalog number is important because the final configuration determines characteristics such as the CM jumper arrangement, filtering and operator-interface configuration.

---

2. Brand and Product Series

The PowerFlex 753 series is an industrial AC-drive platform intended for machinery and industrial automation systems that require controlled motor operation.

The series is designed to cover a broad range of motor sizes and applications, allowing machine builders and system integrators to standardize on a common drive family.

The 20F11RD011AA0NNNNN is positioned in the 480 VAC, 11 A class of the PowerFlex 753 family.

---

3. Product Overview

The 20F11RD011AA0NNNNN is essentially an electronic motor controller that converts fixed-frequency three-phase AC power into a controlled variable-frequency output for an AC motor.

Instead of operating a motor at only one fixed speed, the drive allows the machine controller to regulate motor speed according to production requirements.

A typical system can be arranged as:

Three-Phase AC Power

↓

PowerFlex 753 Drive

↓

Variable-Frequency AC Output

↓

Three-Phase Motor

↓

Mechanical Load

This arrangement allows the motor to accelerate smoothly, operate at adjustable speed and decelerate according to programmed machine requirements.

---

4. Main Electrical Parameters

The 11 A output-current rating is one of the most important specifications when selecting this drive.

For an actual installation, the motor nameplate current should be compared with the drive’s applicable Normal-Duty or Heavy-Duty current rating.

Motor horsepower by itself should not be used as the only selection criterion.

---

5. Normal-Duty Rating

For the Frame 1 configuration, the drive provides approximately:

7.5 HP / 5.5 kW Normal-Duty capacity

This makes the drive suitable for many general-purpose industrial applications.

Normal-Duty applications commonly include loads where the motor does not continuously experience severe overload conditions.

Typical examples include:

• Conveyors
• Centrifugal pumps
• Fans
• Blowers
• Rollers
• Feeders
• Material-transfer systems
• Packaging equipment
• General machine mechanisms

The 11 A current rating provides a useful capacity level between smaller 480 VAC PowerFlex 753 models and larger industrial drives.

---

6. Heavy-Duty Rating

The Frame 1 configuration provides approximately:

5 HP / 4.0 kW Heavy-Duty capacity

Heavy-Duty operation should be considered when the mechanical load requires higher torque capability or more demanding acceleration and deceleration performance.

Typical Heavy-Duty applications can include:

• High-inertia loads
• Frequent acceleration
• Frequent deceleration
• High starting torque
• Reversing applications
• Material-handling machinery
• Feed mechanisms
• Machinery with intermittent overload requirements

The drive should be selected based on the actual motor current and duty cycle rather than simply choosing the highest horsepower number shown on a motor nameplate.

---

7. 480 VAC Three-Phase Design

The 20F11RD011AA0NNNNN belongs to the 480 VAC class.

This makes it appropriate for common industrial three-phase electrical systems.

The drive is intended for applications using three-phase AC power in the approximately 380–480 VAC range.

This voltage class is common in industrial plants, manufacturing facilities, processing equipment and large machine installations.

The actual supply voltage must always be checked against the drive’s applicable installation requirements before commissioning.

---

8. 11 Amp Output Capacity

The 11 A output rating provides a useful balance between physical size and motor capacity.

A machine builder may select this model when a smaller 5 A or 8 A-class drive is insufficient, but a larger drive is unnecessary.

A simplified capacity progression within the same family can be represented as:

5 A

↓

8 A

↓

11 A

↓

14 A

This makes the 11 A model a practical mid-range option for many industrial machines.

---

9. Frame 1 Mechanical Design

The 20F11RD011AA0NNNNN uses a Frame 1 enclosure.

The approximate mechanical dimensions are:

400.5 mm high × 110 mm wide × 211 mm deep

The approximate weight is:

6.0 kg

The relatively narrow 110 mm body can be useful when designing compact control cabinets.

The cabinet must, however, provide additional space around the drive for wiring, ventilation, cable routing and maintenance access.

---

10. Dimensions and Weight

The dimensions should be regarded as approximate Frame 1 mechanical dimensions for planning purposes.

The final cabinet layout should also account for cable-bending radius, ventilation, terminal access and required service clearance.

---

11. IP20 Open-Type Construction

The drive uses an IP20 / NEMA/UL Open Type construction.

This means it is generally intended to be installed inside an appropriate electrical enclosure.

The drive should be protected from direct exposure to:

• Water
• Condensation
• Conductive dust
• Metal particles
• Oil
• Aggressive chemicals
• Excessive humidity
• Mechanical impact

The control cabinet therefore becomes an important part of the complete drive installation.

---

12. Forced-Air Cooling

The drive uses forced-air cooling.

During operation, the power electronics generate heat.

The cooling system moves air through the drive to remove this heat and maintain appropriate internal operating temperatures.

For reliable long-term operation, the cabinet should have suitable thermal management.

Important factors include:

• Ambient temperature
• Cabinet temperature
• Drive loading
• Airflow
• Cooling-fan condition
• Dust accumulation
• Cabinet ventilation
• Spacing between heat-producing components

A drive that is correctly sized electrically can still experience reliability problems if the cabinet temperature becomes excessive.

---

13. EMC Filter

The exact model is configured with an EMC filter.

EMC, or electromagnetic compatibility, is an important consideration for variable-frequency drives because the power stage uses high-speed electronic switching.

This switching can generate high-frequency electrical noise.

A suitable installation should therefore pay attention to:

• Grounding
• Motor-cable routing
• Shielding
• Cable separation
• Cabinet bonding
• Control wiring
• Power wiring

The built-in EMC filtering can help support a properly engineered industrial installation.

---

14. CM Jumper Removed

One of the defining configuration characteristics of this model is:

CM Jumper Removed

This is important because the otherwise similar JA configuration uses the CM jumper installed.

When replacing an existing drive, the complete catalog number should therefore be checked.

It is not advisable to treat every 20F11RD011 configuration as mechanically and electrically identical simply because the current and horsepower ratings appear similar.

---

15. Dynamic Braking

The drive includes a DB transistor.

Dynamic braking is useful when the motor must decelerate a load quickly or when the machine contains significant rotational inertia.

During deceleration, the motor can return energy to the drive’s DC bus.

This regenerative energy can increase DC-bus voltage.

A properly selected external braking resistor can dissipate this energy through the drive’s braking transistor.

Typical applications include:

• High-inertia conveyors
• Rollers
• Feeders
• Packaging machinery
• Material-handling systems
• Rapid-stop machinery
• Reversing applications

The braking resistor itself is not the same thing as the integrated braking transistor.

The drive provides the switching element; the external braking resistor must be selected for the actual braking energy and duty cycle.

---

16. Embedded I/O

The PowerFlex 753 platform includes embedded I/O.

This is particularly useful for machine builders.

Basic machine signals can be connected directly to the drive instead of requiring every signal to pass through separate interface equipment.

Depending on the machine architecture, these signals can be used for functions such as:

• Start
• Stop
• Enable
• Forward
• Reverse
• Fault reset
• Speed reference
• Run status
• Fault status
• Analog reference
• Interlock signals

This can simplify the electrical design of the machine.

---

17. Blank / No HIM Configuration

The exact catalog number is configured with:

Blank / No HIM

HIM means Human Interface Module.

A local operator keypad is therefore not included in this configuration.

This arrangement is particularly suitable for systems where the operator interacts with a centralized HMI.

A typical architecture might be:

Operator HMI

↓

PLC / Controller

↓

PowerFlex 753

↓

AC Motor

This arrangement can be useful when a machine contains multiple drives and the operator interface is centralized.

---

18. AC Input with Precharge

The drive uses an AC input with precharge.

The precharge function controls the initial charging of the DC bus and helps manage the electrical conditions during startup.

The drive also provides DC terminals, which can be relevant when designing braking or other DC-bus-related functions.

This is one reason the PowerFlex 753 is more than a simple basic motor-speed controller.

---

19. Product Advantages

---

20. Main Applications

The 20F11RD011AA0NNNNN can be used in a broad range of industrial motor-control applications.

Typical applications include:

• Conveyor systems
• Material handling
• Packaging machinery
• Feeders
• Pumps
• Fans
• Blowers
• Rollers
• Processing machinery
• Production lines
• Machine tools
• General-purpose industrial machines
• OEM machinery
• Automated handling systems

The actual suitability depends on the motor current, load type, duty cycle, required overload and environmental conditions.

---

21. Conveyor Applications

Conveyors are one of the most natural applications for a PowerFlex 753 drive.

A conveyor motor may need to operate at several different speeds.

For example:

Setup Speed → 20%

Inspection Speed → 40%

Normal Production → 70%

High Throughput → 100%

The drive allows these speed changes to be handled electronically.

Controlled acceleration can also reduce mechanical shock on:

• Belts
• Chains
• Gearboxes
• Couplings
• Shafts
• Bearings

For conveyors with significant inertia, dynamic braking can provide additional stopping capability when correctly designed.

---

22. Packaging Machinery

Packaging machines often require controlled and repeatable motor speeds.

The drive can be used for:

• Product conveyors
• Feed rollers
• Transfer rollers
• Packaging lines
• Product positioning
• Auxiliary mechanisms
• Material feeders

The ability to control acceleration and deceleration can help reduce sudden mechanical movement.

This can be especially useful when the machine contains belts, rollers or other mechanisms that require smooth motion.

---

23. Feeder Applications

Feed mechanisms often require controlled speed.

A feeder that runs too quickly may produce:

• Product accumulation
• Incorrect spacing
• Mechanical impact
• Product damage
• Jamming

A feeder that runs too slowly may reduce production capacity.

The variable-speed capability of the PowerFlex 753 allows the machine controller to select an appropriate motor speed.

---

24. Pump Applications

The drive can be used with suitable three-phase pump motors.

Potential applications include:

• Process-water pumps
• Cooling pumps
• Circulation pumps
• Fluid-transfer systems
• Utility pumps
• Industrial process pumps

For suitable variable-torque applications, motor speed can be adjusted according to actual process demand.

In many pump systems, operating at reduced speed can also provide energy savings compared with continuously running the motor at full speed.

---

25. Fan and Blower Applications

Fans and blowers frequently do not need to operate at maximum speed all the time.

The drive can provide:

Low Air Demand → Low Motor Speed

Medium Air Demand → Medium Motor Speed

High Air Demand → High Motor Speed

This provides much more flexible airflow management than a fixed-speed motor.

It can also reduce energy consumption in suitable variable-torque applications.

---

26. Material-Handling Applications

Material-handling equipment often requires controlled starting and stopping.

Typical examples include:

• Transfer conveyors
• Sorting equipment
• Rollers
• Product-transfer mechanisms
• Pallet-handling equipment
• Feed systems
• Industrial transport mechanisms

The drive’s combination of variable-speed control, embedded I/O and dynamic braking makes it useful for these types of applications.

---

27. Roller Applications

Motor-driven rollers are common in production and logistics systems.

The drive can regulate roller speed according to the production line.

Applications can include:

• Packaging lines
• Conveyor rollers
• Product-transfer rollers
• Material-processing rollers
• Feed rollers

Controlled acceleration can help prevent sudden movement of products on the roller.

---

28. OEM Machine Builder Advantages

For an OEM machine builder, using the PowerFlex 753 platform can simplify product standardization.

Different machines may use different motor sizes, but the electrical architecture can remain based on the same drive family.

For example:

This can help standardize:

• Electrical drawings
• PLC programming
• Machine documentation
• Spare parts
• Commissioning procedures
• Technician training

---

29. Five Recommended Same-Series or Closely Related Models

The following models are useful alternatives or neighboring PowerFlex 753 configurations.

These five models give a useful range around the subject model.

The 20F11RD8P0AA0NNNNN is a logical lower-capacity alternative.

The 20F11RD014AA0NNNNN provides additional current capacity when the motor is larger.

The 20F11RD011JA0NNNNN is particularly relevant when replacing the subject model but the application requires the CM jumper installed configuration.

---

30. Same-Series PowerFlex 753 Selection Table

This provides a straightforward capacity ladder for 480 VAC PowerFlex 753 applications.

---

31. Five Popular Same-Brand Models

These products are useful alternatives when the application does not necessarily require the full PowerFlex 753 platform.

The PowerFlex 525 family is particularly attractive for compact OEM machinery.

The PowerFlex 40 family is useful for more straightforward variable-speed applications.

The PowerFlex 753 is generally better suited to larger industrial systems where integration flexibility and broader drive-system functionality are more important.

---

32. PowerFlex 525 Compared with PowerFlex 753

A PowerFlex 525 can be a very good choice when the machine is compact and the control requirements are straightforward.

The PowerFlex 753 is more appropriate when the application requires a broader industrial-drive architecture.

---

33. PowerFlex 40 Compared with PowerFlex 753

For a simple pump or fan, the PowerFlex 40 can be sufficient.

For a more sophisticated industrial machine, the PowerFlex 753 provides a more scalable platform.

---

34. Typical Conveyor Control Sequence

A conveyor using this drive can operate in the following sequence:

1. Machine Ready

The PLC verifies that all interlocks are satisfied.

2. Drive Enable

The controller enables the PowerFlex 753.

3. Acceleration

The drive accelerates the motor according to the configured acceleration profile.

4. Normal Operation

The drive maintains the required motor speed.

5. Speed Change

The PLC changes the speed reference when production conditions change.

6. Deceleration

When the machine receives a stop command, the drive decelerates the motor.

7. Dynamic Braking

If the application requires additional stopping capability, the braking system can assist with energy dissipation.

This type of control is much smoother than repeatedly switching a motor directly across the AC supply.

---

35. Typical Packaging Application

A packaging line may use the 20F11RD011AA0NNNNN for a conveyor or feed mechanism.

The PLC can determine the required production speed.

The drive then converts that speed reference into the corresponding motor operating condition.

This allows the machine to support:

• Recipe changes
• Production-rate changes
• Setup operation
• Reduced-speed inspection
• Controlled stopping
• Controlled acceleration

This is one of the reasons variable-frequency drives are widely used in automated machinery.

---

36. Typical Pump Application

For a pump application, the basic arrangement is:

Three-Phase Supply

↓

20F11RD011AA0NNNNN

↓

Pump Motor

↓

Pump

↓

Process

The controller can adjust the drive speed according to process demand.

For example:

Low Process Demand → Lower Speed

Medium Process Demand → Medium Speed

High Process Demand → Higher Speed

In a suitable pump system, this can improve process control and reduce unnecessary energy consumption.

---

37. Typical Fan Application

The same basic architecture can be used for fans and blowers.

The drive can adjust motor speed according to:

• Temperature
• Airflow
• Pressure
• Ventilation demand
• Production requirements

This avoids the need to operate the fan continuously at full speed when the process does not require maximum airflow.

---

38. Typical Material-Handling Application

Material-handling equipment often requires smooth starting.

A motor started directly across the line can produce a sudden torque response.

A variable-frequency drive provides a controlled acceleration profile.

This can reduce mechanical stress on:

• Gearboxes
• Chains
• Belts
• Shafts
• Couplings
• Bearings

For systems that stop frequently, controlled deceleration can also be valuable.

---

39. Mechanical Installation

The approximate dimensions of the drive are:

400.5 mm × 110 mm × 211 mm

The approximate weight is:

6.0 kg

The mounting panel should therefore be strong enough to support the drive and associated wiring.

The cabinet should also provide adequate space around the drive.

Important installation considerations include:

• Mounting clearance
• Cable routing
• Air circulation
• Grounding
• Power-terminal access
• Motor-cable routing
• Control-cable separation
• Maintenance access

---

40. Cabinet Design

A good cabinet layout can significantly influence drive reliability.

High-heat devices should not be placed in a way that unnecessarily increases the temperature around the drive.

Potential heat sources include:

• Other variable-frequency drives
• Transformers
• Braking resistors
• Power supplies
• Contactors
• Large switching devices

The cooling path should remain unobstructed.

---

41. Thermal Management

The drive uses forced-air cooling, so the cabinet should allow sufficient air circulation.

Important considerations include:

• Cabinet ambient temperature
• Internal cabinet temperature
• Fan condition
• Air inlet condition
• Air outlet condition
• Dust buildup
• Drive loading

A dusty environment may gradually restrict airflow and increase operating temperature.

Regular inspection is therefore worthwhile.

---

42. EMC Installation

The drive contains an EMC filter, but the complete machine still requires good electrical installation practices.

Recommended design considerations include:

• Appropriate grounding
• Short and well-organized grounding paths
• Proper motor-cable routing
• Separation of control and power wiring
• Suitable cable shielding
• Good cabinet bonding
• Avoiding unnecessary parallel routing of sensitive signal cables alongside motor cables

The drive’s EMC performance should always be considered together with the complete machine installation.

---

43. Maintenance Recommendations

Preventive maintenance can help detect problems before they develop into production downtime.

---

44. Spare-Part Planning

When purchasing or stocking a replacement, the complete catalog number should be recorded.

The difference between:

20F11RD011AA0NNNNN

and

20F11RD011JA0NNNNN

is not merely cosmetic.

The AA version uses the CM jumper removed configuration, while the JA version uses the CM jumper installed configuration.

For this reason, replacement planning should always verify:

• Voltage
• Current
• Power rating
• Frame
• Filtering
• CM jumper configuration
• Dynamic braking
• HIM configuration
• I/O requirements
• Mechanical dimensions

---

45. AA Versus JA Configuration

The two configurations are very close in basic motor-control capability.

The main configuration difference relevant to this catalog number is the CM jumper arrangement.

---

46. Why This Model Is Useful

The 20F11RD011AA0NNNNN occupies a practical position in the PowerFlex 753 family.

It is large enough to handle approximately 7.5 HP Normal-Duty applications, while remaining a relatively compact Frame 1 unit.

Its 11 A output current makes it useful for medium-sized industrial machinery.

The combination of:

• 480 VAC operation
• 11 A output
• 5.5 kW Normal-Duty capacity
• 4.0 kW Heavy-Duty capacity
• Embedded I/O
• Dynamic braking
• EMC filtering
• Forced-air cooling
• Frame 1 construction

makes it a versatile drive for many industrial applications.

52. Final Summary

The Allen-Bradley 20F11RD011AA0NNNNN is a PowerFlex 753 industrial AC drive designed for 480 VAC three-phase motor-control applications.

Its key rating is 11 A output current, with approximately 7.5 HP / 5.5 kW Normal-Duty capability and 5 HP / 4.0 kW Heavy-Duty capability in the Frame 1 configuration.

The drive uses a Frame 1 enclosure with approximate dimensions of 400.5 mm × 110 mm × 211 mm and an approximate weight of 6.0 kg.

It features forced-air cooling, IP20 open-type construction, an EMC filter, CM jumper removed, a dynamic-braking transistor, AC input with precharge, DC terminals, embedded I/O and a blank/no-HIM configuration.

Its combination of electrical capacity and relatively compact physical construction makes it suitable for a wide range of industrial equipment.

The drive is particularly useful for conveyors, feeders, packaging machines, rollers, pumps, fans, blowers, material-handling systems and general-purpose automated machinery.

For OEM applications, one of its strongest advantages is the ability to standardize different machine motor sizes around the PowerFlex 753 family.

For maintenance departments, using a common drive family can simplify troubleshooting, spare-parts planning and technician training.

For system integrators, the embedded I/O, dynamic-braking capability and industrial 480 VAC architecture provide useful flexibility when building a complete motor-control system.

One important point when handling this exact model is the AA configuration.

The 20F11RD011AA0NNNNN uses the CM jumper removed configuration, while the closely related 20F11RD011JA0NNNNN uses the CM jumper installed configuration.

Therefore, when purchasing or replacing this drive, the complete catalog number should be checked rather than selecting a replacement only by horsepower or current rating.

The model itself has been discontinued, with the closely related 20F11RD011JA0NNNNN serving as the direct replacement configuration.

Overall, the 20F11RD011AA0NNNNN remains a practical PowerFlex 753 model for applications requiring an 11 A, 480 VAC, three-phase industrial AC drive, especially where 7.5 HP Normal-Duty performance, 5 HP Heavy-Duty capability, dynamic braking, embedded I/O, EMC filtering and compact Frame 1 installation are important.
