Allen-Bradley 20F11RC2P1AA0NNNNN — PowerFlex 753 0.75 kW AC Drive | Detailed Technical Specifications, Applications, Advantages and Related Models

1. Product Overview

The Allen-Bradley 20F11RC2P1AA0NNNNN is a PowerFlex 753 AC Drive designed for three-phase industrial motor control applications.

This particular model is a compact 400 VAC-class, 2.1 A PowerFlex 753 drive, with a 0.75 kW normal-duty rating and approximately 0.37 kW heavy-duty rating.

It is a Frame 1, forced-air-cooled, IP20 open-type drive with embedded I/O and an AC input configuration with precharge and DC terminals.

The catalog number also identifies an important electrical configuration: the model has EMC filtering with the common-mode capacitor jumper removed and includes an internal dynamic-braking transistor.

The drive is intended for applications where a relatively small three-phase AC motor needs adjustable speed, controlled acceleration, controlled deceleration and integration into an industrial automation system.

Typical applications include small conveyors, compact feeders, fans, pumps, small processing machines, packaging equipment, material-transfer equipment, machine tools and auxiliary machinery.

---

2. Basic Product Identification

The most important point when selecting this drive is its 2.1 A continuous output rating.

Because this is a relatively small current rating, it is intended for small industrial motors rather than medium- or high-power motors.

The drive nevertheless uses the same general PowerFlex 753 architecture found across a much broader range of industrial motor sizes.

That makes it useful when a machine builder wants to maintain a consistent drive platform even for smaller motors.

---

3. Detailed Electrical Parameters

The 2.1 A rating makes this drive particularly suitable for small motors where precise speed control is more important than raw motor power.

The drive should be selected based on the motor’s actual nameplate current rather than horsepower alone.

---

4. Normal-Duty and Heavy-Duty Ratings

One interesting characteristic of this particular model is that the continuous current value remains approximately 2.1 A in both duty categories, while the applicable motor-power rating changes.

This is a good example of why motor selection should be based on the complete drive rating rather than simply comparing horsepower numbers.

For a normal-duty application, the drive can be applied to approximately a 0.75 kW motor, provided the actual motor current is appropriate.

For a heavier-duty application, the applicable motor-power rating is approximately 0.37 kW.

---

5. Brand and Product Series

The product belongs to the PowerFlex 753 series.

The series is designed for industrial applications requiring adjustable motor speed or torque control.

It is not limited to one motor size.

The family covers a wide range of drive ratings, allowing machine builders to use related drive models for small, medium and larger motors.

---

6. Product Introduction

The 20F11RC2P1AA0NNNNN is essentially an electronic motor controller.

Instead of connecting the motor directly to a fixed-frequency AC power source, the drive receives electrical power and generates a controlled output for the motor.

A simplified system looks like this:

PLC / Controller

↓

Speed / Start / Stop Command

↓

20F11RC2P1AA0NNNNN

↓

Three-Phase AC Motor

↓

Machine Mechanism

The drive controls the motor’s operating frequency and voltage.

This makes it possible to operate the motor at different speeds.

For example, a small conveyor motor may need to run at 30% speed during loading and 100% speed during production.

A fan may need to run slowly during normal conditions and faster when ventilation demand increases.

A pump may need variable speed to maintain process pressure or flow.

The drive provides the electrical control required for these applications.

---

7. Why a Small 0.75 kW Drive Can Still Be Useful

Although 0.75 kW is a relatively small motor rating, many industrial machines use motors of this size.

Small motors are commonly found in:

• Feeders
• Small conveyors
• Rollers
• Compact pumps
• Fans
• Small blowers
• Packaging mechanisms
• Positioning mechanisms
• Auxiliary machine functions
• Small processing equipment

For these applications, speed control can be more important than motor power.

A 0.75 kW motor that needs to operate at several different speeds may benefit greatly from a VFD.

---

8. 400 VAC Three-Phase Operation

The 20F11RC2P1AA0NNNNN is designed for the 400 VAC three-phase class.

This makes it suitable for industrial electrical systems operating in the approximate 380–480 VAC range, subject to the specific installation requirements.

The drive is intended for three-phase AC supply and three-phase motor output.

The motor should be checked carefully for:

• Rated voltage
• Rated current
• Rated frequency
• Number of phases
• Motor connection
• Duty rating

The drive’s current rating should be compared directly with the motor nameplate current.

---

9. Frame 1 Construction

The drive uses a Frame 1 mechanical design.

Frame 1 provides a compact package for the smaller PowerFlex 753 ratings.

Approximate physical dimensions are:

400.5 mm high × 110 mm wide × 211 mm deep

Approximate drive weight is:

6.0 kg

The relatively narrow width can be useful in control cabinets.

However, the cabinet designer should provide additional clearance around the drive.

The physical dimensions of the drive itself should not be treated as the total installation footprint.

---

10. Dimensions and Weight

The approximately 6.0 kg weight is relatively manageable for panel installation.

Nevertheless, the mounting panel should be rigid enough to support the drive and should account for vibration when the drive is installed on machinery.

Additional space is required for:

• Power cables
• Motor cables
• Control cables
• Grounding
• Air circulation
• Maintenance
• Terminal access

---

11. Forced-Air Cooling

The drive uses forced-air cooling.

Although the motor power rating is only 0.75 kW, the drive’s power electronics still generate heat during operation.

The cooling system is therefore important.

The cabinet should have sufficient ventilation and should not allow excessive heat to accumulate around the drive.

Particular attention should be paid to:

• Ambient temperature
• Cabinet temperature
• Fan condition
• Dust accumulation
• Air passages
• Adjacent equipment
• Cabinet ventilation

If several drives are installed together, their combined heat output should be included in the cabinet thermal calculation.

---

12. IP20 Open-Type Enclosure

The drive uses an IP20 / NEMA/UL open-type enclosure.

This means the drive is intended to be installed inside an appropriate electrical enclosure.

The drive itself is not designed as a sealed outdoor unit.

The surrounding cabinet should provide the required protection against:

• Water
• Dust
• Oil
• Metal particles
• Chemical contamination
• Excessive humidity
• Mechanical damage

This type of construction is very common for industrial control cabinets.

---

13. EMC Filtering

The model uses an EMC-filtered configuration.

AC drives use high-frequency switching to create the desired motor output.

That switching can generate electrical noise.

The filtering arrangement helps reduce certain conducted electromagnetic disturbances.

Good EMC performance still depends heavily on installation quality.

Important considerations include:

• Grounding
• Shielding
• Motor cable routing
• Control cable routing
• Cabinet bonding
• Separation between power and signal cables
• Correct termination practices

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

---

14. Common-Mode Capacitor Jumper Removed

The AA configuration is important for this exact model.

The catalog number:

20F11RC2P1AA0NNNNN

uses a configuration where the common-mode capacitor jumper is removed.

A closely related configuration is:

20F11RC2P1JA0NNNNN

which has the common-mode capacitor jumper installed.

The electrical ratings are otherwise closely related.

This distinction becomes important when replacing an existing drive.

A replacement should match the intended grounding and electrical configuration rather than being selected only according to kW.

---

15. Dynamic-Braking Transistor

The model includes an internal dynamic-braking transistor.

This allows an external braking resistor to be used when the machine requires controlled or relatively rapid deceleration.

When an AC motor decelerates, energy can flow back toward the drive’s DC bus.

This can cause the DC-bus voltage to rise.

A braking resistor can dissipate the excess energy.

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

Potential applications include:

• Small conveyors
• Packaging machines
• Rapid-cycle machinery
• Rollers
• Material-transfer systems
• Small rotating mechanisms

The correct braking resistor must be selected according to the actual machine inertia and braking duty.

---

16. Embedded I/O

The PowerFlex 753 platform includes embedded I/O.

This makes it possible to connect basic control signals directly to the drive.

Depending on the machine configuration, this can include:

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

This can simplify machine wiring.

For a small machine, the embedded I/O may be sufficient for basic operation.

For a larger automation system, the drive can be connected to the PLC architecture using the appropriate communication and I/O options.

---

17. Blank / No HIM

The catalog number specifies a Blank / No HIM configuration.

HIM means Human Interface Module.

A local keypad is useful during commissioning, but it is not necessary for every machine.

In many OEM machines, the operator interface is already provided by a machine HMI.

In this type of system, the drive can remain inside the cabinet without a local door-mounted keypad.

This can provide a cleaner cabinet design.

---

18. Main Product Applications

18.1 Small Conveyor Systems

Small conveyors are a natural application for this drive.

A conveyor motor may need several operating speeds depending on the production process.

The drive can control:

• Start
• Stop
• Speed
• Acceleration
• Deceleration
• Direction

This can be useful for packaging lines, inspection systems and material-transfer equipment.

---

19. Small Pump Applications

The drive can be used for suitable small pump systems.

Potential applications include:

• Cooling-water circulation
• Small process pumps
• Utility pumps
• Fluid-transfer equipment
• Small circulation systems

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

For appropriate centrifugal-pump applications, reduced speed can also help reduce energy consumption.

---

20. Small Fan and Blower Applications

Small fans and blowers can also benefit from variable-speed control.

Instead of operating continuously at full speed, the motor can be adjusted according to ventilation demand.

Typical uses include:

• Equipment cooling
• Cabinet ventilation
• Small exhaust systems
• Process-air equipment
• Local ventilation systems

The drive provides an electronic method for adjusting fan speed.

---

21. Packaging Equipment

Small packaging mechanisms frequently use relatively small motors.

Examples include:

• Rollers
• Feed mechanisms
• Small conveyors
• Product transfer systems
• Labeling mechanisms
• Auxiliary packaging functions

The drive can provide controlled acceleration and deceleration.

This can improve the mechanical smoothness of the machine.

---

22. Feeder Applications

Small feeders often require adjustable speed.

The speed of the motor determines the material or product feed rate.

The drive can allow the machine controller to change this speed according to production requirements.

Potential applications include:

• Product feeders
• Small material feeders
• Packaging feeders
• Assembly feeders
• Processing equipment

---

23. Small Material-Handling Systems

Material-transfer equipment often benefits from controlled starting.

Even a small conveyor can experience mechanical shock if its motor starts abruptly.

The drive allows the motor to accelerate progressively.

This can reduce stress on:

• Belts
• Rollers
• Chains
• Gearboxes
• Couplings
• Shafts

---

24. Machine Tool Auxiliary Functions

The drive can also be suitable for certain auxiliary motor functions on industrial machines.

Examples may include:

• Cooling fans
• Small pumps
• Auxiliary conveyors
• Feed mechanisms
• Material-transfer systems

The exact application must still be checked against the drive’s current and duty ratings.

---

25. General Industrial Machinery

The 20F11RC2P1AA0NNNNN can be used in many small industrial machines where variable-speed control is required.

Potential applications include:

• Small conveyors
• Small pumps
• Fans
• Blowers
• Feeders
• Rollers
• Packaging equipment
• Processing equipment
• Auxiliary machinery
• Material-transfer mechanisms

---

26. Major Product Advantages

26.1 Compact Motor-Control Solution

The drive is designed for a relatively small motor rating while retaining the PowerFlex 753 platform.

This makes it useful when a machine requires sophisticated drive functionality without requiring a large motor.

---

26.2 0.75 kW Normal-Duty Rating

The 0.75 kW normal-duty rating is suitable for many small industrial motors.

---

26.3 2.1 A Continuous Current

The 2.1 A continuous current rating is the key selection parameter for the model.

---

26.4 Frame 1 Design

The Frame 1 construction provides a relatively compact mechanical package.

---

26.5 400 VAC Three-Phase Operation

The drive fits common 400 VAC industrial power systems.

---

26.6 Embedded I/O

Embedded I/O reduces the need for additional basic drive-interface hardware.

---

26.7 Dynamic-Braking Transistor

The internal DB transistor provides flexibility for applications requiring external braking resistance.

---

26.8 EMC Filtering

The filtered configuration supports industrial EMC requirements when installed correctly.

---

26.9 No-HIM Configuration

The blank/no-HIM arrangement can be useful for PLC- and HMI-controlled OEM machines.

---

26.10 PowerFlex 753 Platform

The biggest system-level advantage is the ability to use a common drive family across a broad range of motor sizes.

This can simplify engineering, commissioning and maintenance.

---

27. Advantages for OEM Machine Builders

For OEM machine builders, the 20F11RC2P1AA0NNNNN is useful when a relatively small motor needs to remain within the same drive architecture used by larger machines.

For example, a machine may have:

• One 0.75 kW motor
• One 4 kW motor
• One 5.5 kW motor
• One 7.5 kW motor

Using related PowerFlex 753 configurations can simplify the overall engineering approach.

Technicians can become familiar with the same general drive family instead of learning completely different drive platforms.

This can reduce training requirements.

It can also simplify spare-parts management.

---

28. Advantages for Maintenance

A variable-frequency drive provides more control and diagnostic information than a basic motor starter.

Depending on the machine configuration, maintenance personnel can monitor:

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

This can make troubleshooting easier.

For example, an unexpected motor-current increase may indicate a mechanical load problem rather than a drive problem.

---

29. Advantages for Small Machines

The 20F11RC2P1AA0NNNNN is particularly interesting for small machines because it combines a relatively low motor-power rating with the PowerFlex 753 platform.

A machine designer does not necessarily need a large motor to benefit from variable-speed control.

A small 0.75 kW motor may still need:

• Multiple operating speeds
• Controlled starting
• Controlled stopping
• Adjustable acceleration
• Adjustable deceleration
• PLC integration
• Fault monitoring
• Dynamic braking

The drive provides a platform for these functions.

---

30. Five Recommended Same-Series Models

The following models are useful PowerFlex 753 comparison choices.

These models provide a convenient progression from approximately 0.75 kW to 5.5 kW.

The 20F11RC2P1AA0NNNNN is the smallest of these examples.

The 20F11RC011AA0NNNNN provides approximately five times the normal-duty power rating of the 0.75 kW model.

---

31. Same-Series Electrical Comparison

The electrical progression is straightforward.

As motor size increases, the required drive current also increases.

This makes it relatively easy to move to a larger PowerFlex 753 configuration while maintaining the same general drive family.

---

32. JA Versions of the Same-Series Models

The corresponding JA configuration is particularly useful when the machine requires the common-mode capacitor jumper installed.

The AA and JA suffixes should not be treated as cosmetic differences.

They represent different common-mode capacitor configurations.

---

33. Five Related Models Under the Same Brand

These models are useful when comparing different power levels or different drive platforms.

They should not automatically be considered drop-in replacements.

Electrical, mechanical, communication and configuration requirements should all be checked before replacement.

---

34. Five Popular Same-Brand Models

The PowerFlex 525 models are generally more compact and are well suited to many machine-building applications.

The PowerFlex 40 family is commonly associated with straightforward general-purpose motor control.

The PowerFlex 753 family is a stronger choice when the application needs a more comprehensive industrial drive platform.

The PowerFlex 755 family is positioned for more advanced motion, speed and torque-control applications.

---

35. 20F11RC2P1AA0NNNNN vs. 20F11RC2P1JA0NNNNN

The closest related model is the JA configuration.

The two models are very closely related.

The main distinction is the common-mode capacitor jumper configuration.

The AA model has the jumper removed.

The JA model has the jumper installed.

---

36. 20F11RC2P1AA0NNNNN vs. 20F11RC3P5AA0NNNNN

The 3.5 A model provides significantly more current and power capacity.

If the motor current is close to or above 2.1 A, moving to the 3.5 A configuration may provide a more appropriate operating margin.

---

37. 20F11RC2P1AA0NNNNN vs. 20F11RC5P0AA0NNNNN

The 5.0 A model is appropriate for a significantly larger motor class.

The 2.1 A model is better suited to compact machines and small motors.

---

38. Application Selection Guide

This table is intended as a starting point.

The motor nameplate current and actual load should always be used for the final selection.

---

39. Installation Considerations

The drive is intended for cabinet installation.

The approximate body dimensions are:

400.5 mm high × 110 mm wide × 211 mm deep

A practical cabinet design should allow additional clearance around the drive.

The following should be considered:

• Airflow
• Heat dissipation
• Cable routing
• Power terminal access
• Control terminal access
• Grounding
• Maintenance space
• Adjacent equipment
• EMC cable routing

The drive should not be tightly enclosed without adequate thermal consideration.

---

40. Motor Cable Considerations

The motor cable is an important part of any VFD installation.

The cable should be selected according to:

• Motor current
• Cable length
• Installation environment
• Insulation requirements
• EMC requirements
• Grounding arrangement

Power and control cables should be routed appropriately.

Control wiring should be protected from unnecessary exposure to high-frequency motor switching noise.

---

41. Maintenance Recommendations

Routine inspection can help maintain reliable operation.

Maintenance personnel should check:

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

The cooling system should be kept clean.

Dust accumulation can reduce airflow and increase internal temperature.

Loose electrical connections should also be corrected according to the appropriate maintenance procedure.

---

42. Product Advantages Summary

---

43. Five Recommended PowerFlex 753 Models

This group provides a useful selection range for small and medium PowerFlex 753 applications.

---

44. Five Popular Same-Brand Models

These products occupy different positions within the overall drive portfolio.

The PowerFlex 525 is particularly attractive for compact machinery.

The PowerFlex 40 is suitable for straightforward general-purpose motor control.

The PowerFlex 753 is a more comprehensive industrial platform.

The PowerFlex 755 is intended for more advanced applications requiring additional control and integration capabilities.

---

45. Catalog Number Configuration

The catalog number 20F11RC2P1AA0NNNNN provides useful information about the drive configuration.

The 20F identifies the PowerFlex 753 family.

The 1 identifies the relevant input arrangement associated with AC input with precharge and DC terminals.

The R identifies the IP20/NEMA/UL open-type Frame 1 construction.

The C identifies the 400 VAC class.

The 2P1 corresponds to the 2.1 A rating and 0.75 kW normal-duty class.

The AA portion is especially important because it indicates the filtered configuration with the common-mode capacitor jumper removed and the applicable dynamic-braking arrangement.

The remaining characters define additional catalog configuration information.

For purchasing, replacement and maintenance, the complete catalog number should always be retained.

---

46. What Makes This Model Different from Larger PowerFlex 753 Drives?

The most obvious difference is output capacity.

The 20F11RC2P1AA0NNNNN is designed for a 2.1 A motor-current class.

A model such as 20F11RC015JA0NNNNN is designed for 15.4 A normal-duty operation.

Both belong to the same general PowerFlex 753 platform, but their applications are very different.

The smaller model is appropriate for compact motor-driven equipment.

The larger model is intended for significantly larger industrial machinery.

This common platform can nevertheless be advantageous for machine builders that need different drive sizes across one product range.

---

47. Small Motor Application Example

Consider a small conveyor using a 0.75 kW three-phase motor.

A traditional starter would primarily provide ON/OFF control.

With the 20F11RC2P1AA0NNNNN, the machine can instead command:

Start

→

Accelerate

→

Run at 60% Speed

→

Increase to 80% Speed

→

Decelerate

→

Stop

This gives the machine controller considerably more flexibility.

---

48. Small Fan Application Example

A ventilation fan may not need to operate at maximum speed continuously.

The drive can allow the fan to operate at different speeds.

For example:

Low Demand → Low Speed

Normal Demand → Medium Speed

High Demand → High Speed

This provides a much more flexible operating system than simple fixed-speed switching.

---

49. Small Pump Application Example

A small circulation pump may need to maintain a particular process condition.

Instead of running continuously at full speed, the drive can adjust motor speed according to the required operating point.

This can improve process control and, for appropriate pump systems, reduce unnecessary energy consumption.

---

50. Small Packaging Machine Example

A packaging machine may use a small motor to move a product or packaging material.

The drive can provide controlled movement.

A typical cycle could be:

Start

↓

Accelerate

↓

Move Product

↓

Decelerate

↓

Stop

↓

Repeat

The controlled motion can reduce mechanical shock and make the machine behavior more repeatable.

53. Final Product Assessment

The Allen-Bradley 20F11RC2P1AA0NNNNN is a compact PowerFlex 753 AC Drive designed for small three-phase industrial motors.

Its primary rating is 2.1 A continuous output current, with a 0.75 kW normal-duty rating and approximately 0.37 kW heavy-duty rating.

The drive operates in the 400 VAC three-phase class and uses a Frame 1, IP20 open-type, forced-air-cooled construction.

Its approximate physical dimensions are 400.5 mm high × 110 mm wide × 211 mm deep, with an approximate weight of 6.0 kg.

For a small motor-control application, the drive provides considerably more functionality than a simple fixed-speed motor starter.

It can provide adjustable speed, controlled acceleration, controlled deceleration, motor-control functions, embedded I/O and integration into a larger industrial automation system.

The AA configuration is also important.

The common-mode capacitor jumper is removed, while the closely related 20F11RC2P1JA0NNNNN has the jumper installed.

This distinction should be considered when replacing an existing unit.

The internal dynamic-braking transistor is another useful feature.

When the machine requires controlled or rapid stopping, an appropriately selected external braking resistor can be used with the braking circuit.

The drive is particularly well suited to small conveyors, feeders, fans, blowers, pumps, packaging mechanisms, rollers, material-transfer equipment and auxiliary machine functions.

For OEMs, the PowerFlex 753 platform provides a useful standardization advantage.

A machine can use the 20F11RC2P1AA0NNNNN for a small 0.75 kW motor while using larger PowerFlex 753 models for larger motors elsewhere in the same machine family.

Overall, the 20F11RC2P1AA0NNNNN can be described as a 400 VAC, three-phase, 2.1 A, 0.75 kW normal-duty, 0.37 kW heavy-duty, Frame 1 PowerFlex 753 AC drive with embedded I/O, forced-air cooling, IP20 open-type construction, EMC filtering, removed CM capacitor jumper, internal dynamic-braking transistor, AC input with precharge, DC terminals and blank/no-HIM configuration.

Its main strengths are compact industrial motor control, flexible speed regulation, embedded I/O, dynamic-braking capability, a standardized PowerFlex 753 platform and compatibility with a wide range of small automated machines.
