1. Product Overview

The 20F11ND2P1JA0NNNNN is an Allen-Bradley PowerFlex 753 AC drive designed for three-phase industrial motor-speed control.

It is a relatively compact member of the PowerFlex 753 family, using a Frame 2 enclosure and a 480 VAC, three-phase electrical configuration.

The drive has a 2.1 A continuous output rating and, in the Frame 2 configuration represented by this catalog number, is rated at 1 HP Normal Duty and 1 HP Heavy Duty. It uses forced-air cooling, embedded I/O, an open-type IP20/IP00 construction, an internal dynamic-braking transistor, a filtered configuration with the CM jumper installed, and a blank front configuration without a factory-installed HIM.

This model is particularly interesting when a machine requires the architecture and flexibility of the PowerFlex 753 platform but the motor itself is relatively small.

It can therefore be used for compact conveyors, small pumps, fans, feeders, machine mechanisms, rollers, positioning-related auxiliary drives and other three-phase motor applications where the motor current falls within the drive’s rating.

4. Electrical Rating

Electrical Parameter	Specification
Model	20F11ND2P1JA0NNNNN
Voltage Class	480 VAC
Input Voltage	380–480 VAC class
Input Phase	3-phase
Continuous Output Current	2.1 A
Normal Duty	1 HP
Heavy Duty	1 HP

Frame	Frame 2

The 2.1 A rating is the key current specification for this particular catalog number.

Although the drive belongs to a sophisticated industrial drive family, this specific model is intended for comparatively small motors.

That makes it useful when the machine designer wants the functionality and architecture of the PowerFlex 753 family without selecting a much larger drive.

---

5. Normal Duty and Heavy Duty Ratings

One detail worth emphasizing is that the exact model description distinguishes between Frame 1 and Frame 2 ratings.

For the Frame 2 configuration represented by 20F11ND2P1JA0NNNNN, the rating is 1 HP Normal Duty and 1 HP Heavy Duty, both associated with the 2.1 A output class.

Rating Category	20F11ND2P1JA0NNNNN
Model	20F11ND2P1JA0NNNNN
Output Current	2.1 A
Normal Duty	1 HP
Heavy Duty	1 HP
Normal Duty Power	Approx. 0.75 kW
Heavy Duty Power	Approx. 0.75 kW
Frame	Frame 2

This is different from some smaller-frame configurations in the same family, so the complete catalog number should always be checked when determining the exact rating.

---

6. Understanding the Catalog Number

The catalog number contains several configuration details.

Catalog Number Section	General Meaning
20F	PowerFlex 753 AC drive family
11	480 VAC class, three-phase
ND2P1	2.1 A Normal Duty configuration
J	Filtered configuration with CM jumper installed
A	Internal dynamic-braking transistor
0	Standard configuration position
NNNNN	No additional selected options in these positions

The complete model is:

20F11ND2P1JA0NNNNN

This level of detail matters when replacing a drive.

A replacement should not be selected simply because the label says “PowerFlex 753.”

The voltage class, current, frame, filtering, braking configuration and operator-interface configuration should all be compared.

---

7. Product Introduction

The 20F11ND2P1JA0NNNNN is a variable-frequency AC drive intended to control the speed and operation of a three-phase AC motor.

A conventional motor starter generally provides basic start and stop control.

A variable-frequency drive goes considerably further.

It can regulate motor speed by controlling the frequency and voltage supplied to the motor.

For a machine designer, this means the motor does not necessarily have to run at full speed all the time.

A conveyor can accelerate gradually.

A pump can operate at a lower speed when less flow is required.

A fan can adjust its speed according to ventilation demand.

A feeder can regulate material flow.

A small roller can be operated at different speeds depending on the machine cycle.

This makes the 20F11ND2P1JA0NNNNN useful as a motor-control component in compact industrial equipment.

---

8. PowerFlex 753 Series Position

The PowerFlex 753 is an industrial AC-drive platform designed around a modular architecture.

The series covers a wide range of motor sizes.

The 20F11ND2P1JA0NNNNN sits toward the low-power end of the 480 VAC three-phase PowerFlex 753 range.

That is one of its most useful characteristics.

A machine may have a relatively small motor but still require more than simple motor starting and stopping.

In such a case, the designer can use a higher-level industrial drive platform rather than selecting a basic low-cost speed controller.

The result can be a more standardized machine architecture.

---

9. Main Product Characteristics

Feature	20F11ND2P1JA0NNNNN
Model	20F11ND2P1JA0NNNNN
Industrial Drive Platform	Yes
AC Motor Speed Control	Yes
Embedded I/O	Yes
Forced-Air Cooling	Yes
Internal DB Transistor	Yes
EMC Filtering	Yes
CM Jumper	Installed
Open-Type Construction	Yes
Frame	Frame 2
Local HIM	Not factory installed
480 VAC Three-Phase	Yes
2.1 A Output	Yes

The combination of these characteristics gives the model a practical balance between relatively small physical size and the functionality expected from an industrial drive platform.

---

10. Dimensions and Weight

The mechanical dimensions are particularly important when the drive is being installed into an existing cabinet.

Mechanical Parameter	Specification
Model	20F11ND2P1JA0NNNNN
Frame Size	Frame 2
Height	424.2 mm
Width	134.5 mm
Depth	212.0 mm
Approx. Weight	7.8 kg
Enclosure	IP20/IP00
Cooling	Forced air
Mounting	Panel / cabinet

The approximately 7.8 kg equipment weight is considerably higher than that of many small compact drives.

This is mainly because the PowerFlex 753 is designed as an industrial platform with a larger mechanical and electrical architecture.

The dimensions also mean that cabinet space should be planned carefully.

The drive itself is only part of the required installation envelope.

Cable bending radius, power terminals, control wiring, airflow and maintenance access all require additional room.

---

11. Forced-Air Cooling

The 20F11ND2P1JA0NNNNN uses forced-air cooling.

This is an important consideration even though the motor rating is only 1 HP.

The drive is part of an industrial drive family and uses a cooling arrangement intended to maintain the internal electronics within an appropriate thermal range.

Cooling Consideration	Recommendation
Cooling Fan	Keep operational
Air Intake	Do not obstruct
Air Exhaust	Maintain clear path
Cabinet Temperature	Keep within permitted range
Dust	Minimize accumulation
Airflow	Provide adequate cabinet ventilation
Nearby Heat Sources	Evaluate
Maintenance	Inspect cooling system periodically

A drive installed in a poorly ventilated enclosure can experience unnecessary thermal stress.

---

12. IP20/IP00 Open-Type Construction

The model uses an IP20/IP00, NEMA/UL Open Type configuration.

This means the drive is generally intended to be incorporated into a suitable electrical cabinet or enclosure.

The drive should not be treated as a completely weatherproof standalone unit.

The surrounding enclosure should provide whatever environmental protection is required by the installation.

Potential environmental concerns include:

• Dust
• Moisture
• Oil mist
• Condensation
• Conductive particles
• Mechanical impact
• Excessive humidity
• Corrosive contaminants

For an industrial machine, enclosure design is therefore part of the overall drive installation.

---

13. Embedded I/O

One of the useful features of the PowerFlex 753 architecture is its embedded I/O.

This allows the drive to participate directly in machine control.

Depending on the system design, signals can include:

• Start command
• Stop command
• Forward command
• Reverse command
• Run status
• Fault indication
• Reset
• External interlock
• Speed reference
• Process feedback

This can simplify the control cabinet because basic drive-related signals do not necessarily require a separate interface for every function.

---

14. Dynamic-Braking Transistor

The catalog configuration includes an internal dynamic-braking transistor.

This can be useful when the motor needs to decelerate under controlled conditions.

When an AC motor decelerates, mechanical energy can be returned to the drive’s DC bus.

The resulting DC-bus voltage can rise.

A dynamic-braking system can direct this energy into a braking resistor where the energy is converted into heat.

The internal transistor provides the switching function required by the braking circuit.

It is important to understand that:

Internal DB transistor ≠ complete braking resistor system.

The braking resistor itself may need to be selected separately depending on the application.

---

15. Braking Applications

The braking function can be particularly useful for machines such as:

• Small conveyors
• Rollers
• Feeders
• Small lifting mechanisms
• Rotating equipment
• High-inertia machine components
• Machines requiring relatively fast stopping

The braking requirements depend on the actual mechanical system.

Important factors include:

Braking Factor	Importance
Motor Power	Determines energy scale
Motor Speed	Higher speed can mean more stored energy
Load Inertia	Major factor
Deceleration Time	Shorter stopping time increases braking demand
Stop Frequency	Repeated braking increases average energy
Braking Resistor	Must be appropriately selected
Ambient Temperature	Affects resistor heat dissipation

---

16. Filtered Configuration

The model is configured as Filtered, CM Jumper Installed.

This configuration is useful when electromagnetic compatibility is an important part of the electrical design.

However, an EMC filter alone does not guarantee a trouble-free installation.

The machine designer should also pay attention to:

• Motor cable routing
• Grounding
• Shielding
• Cabinet bonding
• Separation of power and signal cables
• Cable length
• Control wiring
• Proper termination

For example, sensitive analog signals should generally not be routed directly alongside high-power motor cables over long distances.

---

17. No Factory-Installed HIM

The catalog number specifies:

Blank — No HIM

HIM refers to the Human Interface Module.

This means the particular catalog configuration does not include a factory-installed local operator interface.

That can be an advantage in applications where the machine already has a centralized HMI or PLC-based control system.

It can also reduce unnecessary hardware on the front of the drive.

A local interface can be added separately when required for commissioning or maintenance.

---

18. Product Applications

18.1 Small Conveyors

The 20F11ND2P1JA0NNNNN is well suited to compact conveyor applications where the motor is within the 2.1 A / 1 HP rating.

A variable-frequency drive can provide controlled acceleration and deceleration.

This can reduce sudden mechanical stress on:

• Conveyor belts
• Rollers
• Couplings
• Gearboxes
• Chains
• Bearings

For a machine that starts and stops frequently, controlled acceleration can also improve the overall operating feel of the system.

---

19. Small Material-Handling Systems

Compact material-handling machines often require adjustable motor speed.

For example, a roller may need to run slowly during product loading and faster during transportation.

A drive allows the speed command to be changed without changing the mechanical transmission ratio.

This can simplify machine design.

Applications may include:

• Small transfer conveyors
• Roller conveyors
• Feed mechanisms
• Product transport systems
• Compact handling equipment

---

20. Small Pumps

A 1 HP-class drive can be used for many small pump applications.

Typical examples include:

• Circulation pumps
• Cooling pumps
• Transfer pumps
• Process pumps
• Small water systems

Instead of running the motor continuously at full speed, the drive can adjust speed according to the process requirement.

This can provide better control of flow.

---

21. Small Fans and Blowers

The drive can also be used for small ventilation and air-moving equipment.

Typical applications include:

• Machine ventilation
• Cooling fans
• Exhaust fans
• Small blowers
• Air-handling equipment

Variable-speed operation can make the system more flexible than simple full-speed operation.

---

22. Feeders and Dosing Mechanisms

Small feeders can benefit from variable-speed control.

A feeder motor can be operated at different speeds according to the required material flow.

The drive can therefore become part of the process-control system rather than simply functioning as a motor starter.

Typical applications include:

• Small material feeders
• Dosing mechanisms
• Product feeders
• Packaging-line mechanisms
• Small bulk-material systems

---

23. Rollers and Machine Mechanisms

Many industrial machines contain individual rollers or auxiliary rotating mechanisms.

These motors may not require a large amount of power, but they may need adjustable speed.

The 20F11ND2P1JA0NNNNN is suitable for this type of application when the motor current remains within its rating.

Examples include:

• Machine rollers
• Auxiliary rollers
• Small belt drives
• Processing rollers
• Material-positioning mechanisms

---

24. Packaging Machinery

Packaging equipment often contains several small motors.

These motors may control:

• Feed belts
• Rollers
• Conveyors
• Product positioning
• Material feeding
• Auxiliary mechanisms

A variable-frequency drive can allow each motor to be adjusted independently.

For OEM equipment, this can make machine tuning easier during commissioning.

---

25. Advantages of the Product

25.1 Compact PowerFlex 753 Configuration

The biggest advantage is that this is a Frame 2 PowerFlex 753 rather than a basic standalone motor controller.

The drive provides access to a broader industrial architecture while maintaining a relatively modest 1 HP motor rating.

---

25.2 2.1 A Output Capability

The 2.1 A output rating is appropriate for the intended motor class.

It provides a useful solution for 480 VAC three-phase motors around the 1 HP range.

---

26. 1 HP Normal Duty and Heavy Duty

Unlike configurations where the Normal Duty and Heavy Duty horsepower ratings differ substantially, this Frame 2 catalog configuration is listed as 1 HP ND / 1 HP HD.

That makes the model relatively straightforward to evaluate for applications around this motor-power level.

---

27. Embedded I/O

Embedded I/O can reduce the need for additional interface equipment.

For a compact machine, reducing the number of separate control components can help simplify:

• Panel wiring
• Electrical drawings
• Troubleshooting
• Commissioning
• Maintenance

This can be particularly useful for OEM machine builders.

---

28. Internal Dynamic Braking

The internal DB transistor is another useful feature.

It means the drive is prepared for a dynamic-braking arrangement without requiring an entirely separate external switching device.

For machines with controlled stopping requirements, this can make the overall drive system more practical.

---

29. Filtered Configuration

The filtered configuration is another advantage where EMC considerations are important.

The drive is therefore not simply a basic power-conversion device.

Its configuration has been selected with industrial electrical integration in mind.

---

30. Industrial Cabinet Integration

The Frame 2 format allows the drive to be integrated into an electrical cabinet.

Its approximately 134.5 mm width is relatively narrow compared with larger PowerFlex 753 frames.

That can be helpful when multiple pieces of equipment must fit into the same control panel.

The 212 mm depth and 424.2 mm height should still be considered carefully when planning cabinet layout.

---

31. Advantages for Machine Builders

For an OEM machine builder, a standardized drive platform can be valuable.

Instead of using completely different drive families for every motor size, a machine builder can use related drive architectures across different machines.

This can simplify:

• Engineering
• Electrical drawings
• Parameter management
• Commissioning
• Maintenance training
• Spare-parts management
• Troubleshooting

The 20F11ND2P1JA0NNNNN is particularly useful where a small motor still needs an industrially structured drive system.

---

32. Advantages for Maintenance Teams

A maintenance department that already works with PowerFlex 750-Series equipment may find this model easier to manage because the general platform is familiar.

Technicians can work with similar concepts for:

• Parameter setup
• Fault diagnosis
• Motor configuration
• Control signals
• Drive replacement
• Preventive maintenance

The exact catalog number should still be verified before replacement.

---

33. Five Recommended Same-Series Models

The following models are useful related PowerFlex 753 configurations around the lower-power end of the series.

Model	Series	Voltage	Output Current	ND Rating	HD Rating	Frame	Approx. Dimensions	Approx. Weight

20F11ND8P7JA0NNNNN	PowerFlex 753	480 VAC, 3-phase	8.7 A	5 HP	5 HP	2	424.2 × 134.5 × 212 mm	7.8 kg
20F11ND011JA0NNNNN	PowerFlex 753	480 VAC, 3-phase	11.5 A	7.5 HP	7.5 HP	2	424.2 × 134.5 × 212 mm	7.8 kg
20F11ND014JA0NNNNN	PowerFlex 753	480 VAC, 3-phase	14 A	10 HP	10 HP	2	424.2 × 134.5 × 212 mm	7.8 kg

The PowerFlex 753 rating tables show the progression from the 2.1 A / 1 HP configuration through higher-current Frame 2 models.

The dimensions and weight remain approximately the same across these Frame 2 configurations, although exact installed accessories and enclosure arrangements can affect the final installation envelope.

34. Same-Series Comparison

Parameter	20F11ND2P1JA0NNNNN	20F11ND3P4JA0NNNNN	20F11ND5P0JA0NNNNN	20F11ND8P7JA0NNNNN	20F11ND011JA0NNNNN

This comparison shows why the 20F11ND2P1JA0NNNNN is a useful starting point when the motor is only around 1 HP.

If the motor current increases, the same general drive family provides progressively larger current ratings.

---

35. Five Same-Brand Popular Models

For applications where the motor is smaller and a compact drive is preferred, the following models are useful alternatives from the same brand.

Model	Series	Voltage	Phase	Current	Power Class	Frame	Approx. Dimensions H × W × D	Approx. Weight
25B-D010N114	PowerFlex 525	380–480 VAC	3-phase	10.5 A	5 HP / 4.0 kW	B	152 × 87 × 172 mm	1.6 kg
25B-D017N114	PowerFlex 525	380–480 VAC	3-phase	17 A	10 HP / 7.5 kW	C	220 × 109 × 184 mm	2.3 kg
25B-D024N114	PowerFlex 525	380–480 VAC	3-phase	24 A	15 HP / 11 kW	D	260 × 130 × 212 mm	3.9 kg
25B-D030N114	PowerFlex 525	380–480 VAC	3-phase	30 A	20 HP / 15 kW class	D	260 × 130 × 212 mm	3.9 kg
25B-E012N104	PowerFlex 525	525–600 VAC	3-phase	12 A	10 HP / 7.5 kW	C	220 × 109 × 184 mm	2.3 kg

These are related products from the same brand but belong to a different product series.

They are especially useful when physical compactness is more important than the broader architecture of the PowerFlex 753.

---

36. PowerFlex 753 vs. PowerFlex 525 Type of Selection

Consideration	20F11ND2P1JA0NNNNN	25B-D010N114	25B-D017N114	25B-D024N114	25B-D030N114
Product Series	PowerFlex 753	PowerFlex 525	PowerFlex 525	PowerFlex 525	PowerFlex 525
Voltage	480 VAC class	380–480 VAC	380–480 VAC	380–480 VAC	380–480 VAC
Output Current	2.1 A	10.5 A	17 A	24 A	30 A
Approx. Power	1 HP	5 HP	10 HP	15 HP	20 HP
Frame	2	B	C	D	D
Approx. Weight	7.8 kg	1.6 kg	2.3 kg	3.9 kg	3.9 kg
Physical Size	Larger	Very compact	Compact	Compact	Compact
Main Strength	Industrial 753 architecture	Compact drive	Compact drive	Higher compact-drive capacity	Higher compact-drive capacity

The comparison demonstrates an important point.

The 20F11ND2P1JA0NNNNN is not necessarily the smallest or lightest solution for a 1 HP motor.

Its value comes from the PowerFlex 753 platform and its industrial architecture, rather than simply from horsepower.

---

37. Recommended Model by Application Size

Approximate Motor Power	Recommended Model	Series	Approx. Current
1 HP	20F11ND2P1JA0NNNNN	PowerFlex 753	2.1 A
2 HP	20F11ND3P4JA0NNNNN	PowerFlex 753	3.4 A
3 HP	20F11ND5P0JA0NNNNN	PowerFlex 753	5.0 A
5 HP	20F11ND8P7JA0NNNNN	PowerFlex 753	8.7 A
7.5 HP	20F11ND011JA0NNNNN	PowerFlex 753	11.5 A
10 HP	20F11ND014JA0NNNNN	PowerFlex 753	14 A

This table is intended as a practical comparison.

The final drive selection should always be based on motor nameplate current, voltage, load characteristics, overload requirements and operating conditions.

---

38. Small Conveyor Application

A small conveyor may use a 1 HP motor but still require speed adjustment.

For example, the conveyor may transport products between two machine stations.

During startup, the belt needs to accelerate smoothly.

During normal operation, it may run at a constant speed.

During stopping, controlled deceleration may be desirable.

The 20F11ND2P1JA0NNNNN can perform these functions while also providing a more structured industrial drive solution.

---

39. Small Pump Application

For a small pump, variable speed can be used to adjust flow.

Instead of continuously operating the pump at full speed, the drive can lower motor speed when the process demand decreases.

This can improve process flexibility.

The actual energy benefit depends heavily on the pump and piping system.

The drive should therefore be viewed primarily as a speed and process-control device, with energy savings being an application-dependent benefit.

---

40. Small Fan Application

A small fan can also benefit from variable-speed control.

For example, a machine may require high airflow during heavy production and lower airflow during standby operation.

The drive can adjust motor speed accordingly.

This can provide smoother airflow control than simply switching the motor between ON and OFF.

---

41. Small Feeder Application

A feeder may require precise control of material flow.

A variable-frequency drive allows motor speed to be adjusted according to the desired feed rate.

For example:

Low speed → startup

Medium speed → normal feeding

High speed → increased production

Low speed → shutdown

This type of speed profile can be programmed according to the machine’s control strategy.

---

42. Small Roller Application

A roller mechanism often requires adjustable speed.

A fixed-speed motor combined with mechanical gearing can work, but changing the operating speed may require mechanical changes.

A variable-frequency drive provides an electronic method of changing speed.

This can simplify machine adjustment.

---

43. Packaging Machine Application

Packaging machines frequently contain many small motor-driven mechanisms.

The 20F11ND2P1JA0NNNNN can be considered for applications such as:

• Small conveyors
• Feed rollers
• Product positioning
• Film-handling mechanisms
• Auxiliary drives
• Small transport mechanisms

The drive’s embedded I/O can also be useful where the motor-control signals need to be integrated directly into the machine-control architecture.

---

44. Machine Builder Benefits

For machine builders, the main benefits are not limited to motor speed.

The larger advantage is platform standardization.

A machine builder may use related PowerFlex 753 models across multiple machine sizes.

For example:

Machine Motor	Possible PowerFlex 753 Model
1 HP	20F11ND2P1JA0NNNNN
2 HP	20F11ND3P4JA0NNNNN
3 HP	20F11ND5P0JA0NNNNN
5 HP	20F11ND8P7JA0NNNNN
7.5 HP	20F11ND011JA0NNNNN
10 HP	20F11ND014JA0NNNNN

This type of progression can reduce the number of completely different drive platforms a company needs to support.

---

45. Maintenance Advantages

A standardized drive family can make maintenance work more predictable.

Technicians can become familiar with:

• Drive parameter structures
• Fault-handling procedures
• Motor setup
• Control wiring
• Cooling arrangements
• Braking concepts
• Replacement procedures
• Cabinet layouts

For facilities containing multiple PowerFlex 753 drives, using related models can simplify spare-parts planning.

---

46. Installation Considerations

Installation Area	Important Consideration
Input Power	Verify 380–480 VAC class compatibility
Phase	Three-phase
Motor	Verify nameplate current
Drive Current	2.1 A
Cabinet	Provide suitable enclosure
Airflow	Maintain adequate ventilation
Grounding	Use appropriate industrial grounding
EMC	Plan cable routing carefully
Motor Cable	Use suitable motor cable
Control Cable	Separate from high-power wiring where appropriate
Braking	Evaluate braking requirements
Mounting	Secure Frame 2 mounting
Maintenance	Provide access for service

---

47. Cabinet Design

The drive’s approximate mechanical dimensions are:

424.2 mm high

134.5 mm wide

212.0 mm deep

The actual cabinet should be larger than these dimensions.

Additional space may be needed for:

• Incoming power cables
• Motor cables
• Control wiring
• Grounding connections
• Air circulation
• Cable bends
• Maintenance access
• Adjacent components

A common cabinet-design mistake is to calculate only the drive’s external dimensions.

The installation envelope should also include wiring and service requirements.

48. Thermal Management

Although the motor rating is only 1 HP, the drive is still forced-air cooled.

The cabinet designer should therefore avoid placing the drive next to equipment that produces excessive heat.

If several drives are installed in one cabinet, the combined thermal load should be evaluated.

Potential heat sources include:

• Drives
• Power supplies
• Transformers
• Contactors
• Braking resistors
• Other power electronics

Good airflow management is particularly important in a tightly packed cabinet.

49. EMC Considerations

The filtered configuration is useful, but proper cabinet construction remains important.

Good practices include:

• Keeping motor cables away from sensitive signal cables
• Using appropriate grounding
• Minimizing unnecessary cable loops
• Maintaining good cabinet bonding
• Properly terminating cable shields where required
• Avoiding long parallel runs of motor and analog cables
• Maintaining a clean control-power separation

These details often have a larger practical impact on machine reliability than simply selecting a drive with an EMC filter.

50. Braking Considerations

The internal DB transistor is useful, but the actual braking resistor should be selected according to the machine.

A small conveyor that stops occasionally has a very different braking requirement from a mechanism that accelerates and decelerates every few seconds.

The designer should consider:

Parameter	Question
Motor Speed	How fast does the motor operate?
Load Inertia	How much rotating energy is stored?
Stop Time	How quickly must the machine stop?
Stop Frequency	How often does braking occur?
Resistor Rating	Can the resistor dissipate the required energy?
Ambient Temperature	Can heat be safely removed?

57. Final Evaluation

The 20F11ND2P1JA0NNNNN is a compact Allen-Bradley PowerFlex 753 AC drive for 480 VAC three-phase motor applications.

Its 2.1 A output rating, 1 HP Normal Duty rating and 1 HP Heavy Duty rating place it at the low-power end of the PowerFlex 753 range.

The product is built around a Frame 2 mechanical design.

Its approximate dimensions of 424.2 × 134.5 × 212.0 mm and approximate weight of 7.8 kg make it substantially larger than many compact low-power drives, but this is balanced by the industrial architecture and expansion capability associated with the PowerFlex 753 platform.

The model includes embedded I/O, which can simplify machine integration.

Its filtered configuration and installed CM jumper are useful for industrial electrical installations where EMC needs to be considered.

The internal dynamic-braking transistor provides another useful feature for machines that need controlled deceleration.

The absence of a factory-installed HIM can also be appropriate for machines where operator control is handled through a separate HMI or control system.

In practical terms, this model makes the most sense when the motor itself is small but the machine requires a more structured industrial drive platform.

It can be considered for small conveyors, rollers, pumps, fans, blowers, feeders, packaging mechanisms, material-handling equipment and auxiliary machine drives.

For applications requiring more motor power, the related models 20F11ND3P4JA0NNNNN, 20F11ND5P0JA0NNNNN, 20F11ND8P7JA0NNNNN, 20F11ND011JA0NNNNN and 20F11ND014JA0NNNNN provide a logical progression within the same series.

For applications where a much more compact physical drive is preferred, the PowerFlex 525 models listed above can be considered, subject to the application’s electrical, control and installation requirements.

The most important specifications of the 20F11ND2P1JA0NNNNN are therefore:

Brand: Allen-Bradley

Product Series: PowerFlex 753

Product Family: PowerFlex 750-Series

Product Type: AC Variable-Frequency Drive

Voltage: 480 VAC class

Input: 3-phase

Output: 3-phase

Continuous Output Current: 2.1 A

Normal Duty: 1 HP

Heavy Duty: 1 HP

Frame: Frame 2

Cooling: Forced air

Enclosure: IP20/IP00, NEMA/UL Open Type

Embedded I/O: Yes

Filtering: Filtered

CM Jumper: Installed

Dynamic Braking: Internal DB transistor

HIM: Blank / No HIM

Approximate Dimensions: 424.2 × 134.5 × 212.0 mm

Approximate Weight: 7.8 kg

Typical Applications: Small conveyors, rollers, pumps, fans, feeders, packaging machinery and auxiliary industrial motor systems.

Overall, the 20F11ND2P1JA0NNNNN is best viewed as a small-motor, industrial-platform PowerFlex 753 drive.

Its main value is not simply its 1 HP rating.

The stronger reason to select it is the combination of industrial architecture, embedded I/O, configurable control, dynamic-braking capability, filtered configuration and compatibility with a broad family of related PowerFlex 753 drives.

For a machine that only needs basic speed control, a smaller compact drive may be physically easier and less expensive.

For a machine that benefits from a standardized industrial drive architecture and expects future expansion or commonality with larger PowerFlex 753 installations, the 20F11ND2P1JA0NNNNN is a much more compelling choice.
