Allen-Bradley 20F14NF015JN0NNNNN — Detailed Product Specifications, Product Introduction, Applications, Advantages and Recommended Models

1. Product Overview

The 20F14NF015JN0NNNNN is a PowerFlex 753 AC Drive designed for industrial motor control applications using a 690 VAC three-phase electrical system.

It is an air-cooled, open-type, Frame 6 drive with a 15 A output rating. Its rated capacity is 11 kW under Normal Duty and 7.5 kW under Heavy Duty.

This particular configuration is a common-bus DC-input drive with precharge, rather than a conventional standalone AC-input drive. It is therefore especially suitable for industrial systems where several drives share a common DC bus or where the machine has been designed around a common-DC power architecture.

The drive is configured with filtering and the common-mode capacitor jumper installed, has no internal dynamic-braking transistor, and is supplied in a blank configuration without a standard HIM operator interface.

With its 690 VAC voltage class, 15 A output capacity and Frame 6 mechanical construction, the model is positioned between smaller industrial drives and the much larger high-current Frame 6 and Frame 7 configurations.

It can be used for pumps, fans, conveyors, mixers, compressors, material-handling machinery, process equipment and other industrial applications where adjustable motor speed, controlled acceleration and reliable motor protection are required.

4. Normal-Duty and Heavy-Duty Ratings

The distinction between Normal Duty and Heavy Duty is very important when selecting this model.

Under Normal Duty, the drive is rated at 15 A continuous output and 11 kW.

Under Heavy Duty, the continuous output rating becomes 12 A, with a corresponding 7.5 kW power rating.

The higher short-term current capability allows the drive to handle temporary overload conditions, but the actual application must still be evaluated according to the motor nameplate current and machine load.

Rating Category	Continuous	60 Seconds	3 Seconds	Power
Normal Duty	15 A	16.5 A	22.5 A	11 kW
Heavy Duty	12 A	18 A	22.5 A	7.5 kW

Normal Duty is generally more appropriate for applications where the load is relatively smooth and does not continuously require high starting or overload torque.

Heavy Duty is more appropriate for applications with higher torque requirements, frequent acceleration, shock loading or other demanding operating conditions.

The motor’s actual full-load current should always be compared with the applicable drive rating.

---

5. Product Model Configuration

The catalog number 20F14NF015JN0NNNNN identifies a particular combination of voltage, current, frame, filtering and other configuration characteristics.

The important configuration features are summarized below.

Configuration	Description
Voltage Class	690 VAC
Current Class	15 A
Duty Rating	11 kW ND / 7.5 kW HD
Frame	6
Input	DC Input with Precharge
Architecture	Common DC Bus
Cooling	Air Cooled
Enclosure	Open Type
Filtering	Filtered
CM Jumper	Installed
Dynamic Braking	None
HIM	Blank / No HIM

This configuration is particularly useful when replacing or expanding an existing common-bus drive system.

---

6. What Is a Common-DC-Bus Drive?

The 20F14NF015JN0NNNNN is different from a conventional standalone AC-input variable-frequency drive.

A conventional drive generally receives AC power and converts it internally into a DC bus before generating the variable-frequency motor output.

A common-bus drive instead receives DC power from a common DC power architecture.

This arrangement can be useful in machines containing several drives.

For example, one drive may be accelerating while another drive is decelerating. Depending on the system architecture, the shared DC bus can allow energy to be managed more effectively between different drive sections.

Common-bus systems are therefore frequently considered for:

• Multi-drive machinery
• Production lines
• Material-processing systems
• Coordinated conveyor systems
• Winding equipment
• Unwinding equipment
• Large machine systems
• Regenerative systems
• Industrial automation platforms

The common-bus architecture is one of the defining characteristics of this model.

---

7. Product Introduction

The 20F14NF015JN0NNNNN is designed to control the speed and torque of three-phase AC motors in industrial environments.

The drive regulates the electrical frequency and voltage delivered to the motor, allowing the motor to operate at different speeds instead of being limited to the fixed speed associated with the incoming power frequency.

This provides controlled starting, adjustable running speed and controlled stopping.

For industrial machinery, these functions can reduce mechanical shock and improve process control.

For example, a conveyor can accelerate gradually instead of starting abruptly.

A pump can operate at a lower speed when full flow is not required.

A fan can adjust its speed according to the ventilation requirement.

A mixer can operate at different speeds during different stages of a production process.

The drive can also provide operating information and diagnostic information that can be used by maintenance personnel and machine-control systems.

---

8. Why the 690 VAC Rating Is Important

The 690 VAC rating is one of the most important features of this model.

Industrial motors are available in several voltage classes. A 690 V motor system can provide an efficient method of distributing power for industrial machinery because higher voltage means lower current for the same approximate power level.

Lower current can provide practical advantages such as:

• Reduced cable current
• Reduced voltage drop
• Lower conductor losses
• More manageable power distribution
• Better suitability for larger industrial installations
• Efficient motor power distribution

This makes the model particularly useful in industrial plants and machines designed around 690 V motor systems.

However, the motor nameplate voltage and the actual electrical system must be compatible with the drive.

---

9. Product Applications

9.1 Pump Systems

The 20F14NF015JN0NNNNN can be used for appropriately sized industrial pump applications.

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

Typical applications include:

• Industrial water circulation
• Cooling-water systems
• Process-water systems
• Filtration systems
• Wastewater systems
• Chemical-process pumps
• Utility pumps

For variable-torque pump applications, operating at a lower speed when full capacity is not required can also reduce energy consumption.

The drive therefore provides both process-control benefits and potential energy-saving benefits.

---

10. Fan and Blower Systems

Industrial fans and blowers frequently benefit from adjustable speed.

A fan does not always need to operate at maximum speed.

The drive can receive a speed reference from the machine-control system and adjust the motor according to:

• Airflow requirements
• Temperature
• Pressure
• Production rate
• Furnace conditions
• Ventilation requirements
• Exhaust requirements

Applications can include:

• Industrial ventilation
• Dust collection
• Furnace systems
• Air-handling equipment
• Cooling equipment
• Process exhaust
• Industrial HVAC systems

For variable-torque fan loads, speed reduction can produce substantial reductions in power consumption.

---

11. Conveyor Systems

Conveyors are one of the most common applications for variable-frequency drives.

The 20F14NF015JN0NNNNN can provide controlled acceleration and deceleration for appropriately sized conveyor motors.

This can reduce mechanical shock on:

• Belts
• Gearboxes
• Couplings
• Shafts
• Bearings
• Rollers
• Conveyor structures

The ability to control acceleration is particularly useful when the conveyor is carrying heavy or sensitive materials.

A controlled stop can also reduce sudden movement of products on the conveyor.

---

12. Mixer and Agitator Systems

Mixers and agitators often have changing torque requirements.

A mixer may have a relatively low load when empty but require substantially more torque when material is added.

The drive can gradually accelerate the motor and then maintain a selected operating speed.

Typical applications include:

• Chemical mixing
• Food processing
• Plastics
• Paint production
• Water treatment
• Building materials
• Industrial processing

Speed can be adjusted to suit the process rather than keeping the motor at one fixed speed.

---

13. Compressor Applications

The drive can also be used with suitably sized compressors.

Controlled acceleration can reduce mechanical shock during startup.

Applications can include:

• Industrial air systems
• Process equipment
• Refrigeration-related machinery
• Manufacturing utility systems
• Process-gas equipment

Compressor applications should be checked carefully because some compressors have significant starting-torque requirements.

---

14. Material-Handling Applications

The drive can be used in material-handling systems where motor speed needs to change according to the production process.

Examples include:

• Feeders
• Rollers
• Conveyors
• Material transfer equipment
• Processing lines
• Packaging machinery
• Sorting systems

The ability to coordinate drive speed with other machine functions is particularly valuable in automated production environments.

---

15. Advantages of the 20F14NF015JN0NNNNN

15.1 690 VAC Industrial Capability

The 690 VAC rating allows this model to work with high-voltage industrial motor systems.

This is especially useful in facilities where 690 V motors are already part of the plant electrical architecture.

---

15.2 11 kW Normal-Duty Capacity

With a 15 A continuous output rating and 11 kW Normal-Duty capacity, the drive can handle a useful range of medium-power industrial motors.

This makes it suitable for applications that are too demanding for many compact low-power drives while remaining considerably smaller than high-current Frame 6 and Frame 7 drives.

---

15.3 7.5 kW Heavy-Duty Capacity

For demanding applications, the Heavy-Duty rating provides 12 A continuous output and 7.5 kW power capacity.

This makes it possible to use the drive for applications with greater torque requirements, provided the motor current remains within the applicable rating.

---

15.4 Common-Bus Architecture

The common-DC-bus configuration is particularly useful for machines containing multiple drives.

A shared DC architecture can simplify certain power-system designs and may provide opportunities for more efficient management of energy between drive sections.

---

15.5 Frame 6 Construction

Frame 6 provides a useful compromise between electrical capacity and physical size.

The drive is substantially more compact than the very large high-current configurations used for large motors.

---

15.6 Air-Cooled Design

Air cooling is a practical solution for industrial control cabinets.

It avoids the additional complexity associated with liquid cooling and can simplify maintenance.

The cabinet still needs sufficient airflow and heat-dissipation capability.

---

15.7 Filtered Configuration

The filtered configuration helps address electromagnetic compatibility requirements.

This is useful in industrial cabinets containing:

• Drives
• PLCs
• Sensors
• Communication equipment
• Contactors
• Relays
• Switching power supplies

Correct cable routing and grounding remain important even when filtering is provided.

---

15.8 Blank / No HIM Configuration

The absence of a standard HIM is useful in automated equipment where the drive is controlled through an external control system.

This can be particularly appropriate for:

• PLC-controlled machinery
• Centralized operator panels
• Network-controlled systems
• Automated production lines

---

16. Motor-Control Capabilities

The PowerFlex 753 platform is designed to provide several levels of motor-control performance.

Depending on the complete configuration, application and installed options, the platform can support control strategies such as:

Control Method	Typical Application
V/Hz	Simple speed control
Sensorless Vector	Improved speed and torque regulation
Vector Control	Higher-performance motor applications
Closed-Loop Control	Applications using motor feedback
Speed Control	Constant or variable speed processes
Torque Control	Applications requiring controlled torque
Position-Oriented Applications	Specialized machine control

The appropriate control mode depends on the motor type, load characteristics and machine-control requirements.

---

17. Protection and Diagnostic Functions

A major advantage of an industrial drive is the amount of operating information that can be monitored.

Depending on the final configuration, useful information can include:

• Motor current
• Output frequency
• Motor speed
• Drive temperature
• DC-bus voltage
• Fault status
• Warning status
• Operating state
• Load information
• Communication status

This information can help maintenance technicians determine whether a problem is associated with the drive, motor, wiring, mechanical load or control system.

---

18. Installation Requirements

The 20F14NF015JN0NNNNN is an open-type drive.

It should therefore be installed inside an appropriate electrical enclosure or cabinet that provides suitable environmental protection.

The cabinet should provide:

• Adequate ventilation
• Heat dissipation
• Electrical clearance
• Correct grounding
• Proper cable routing
• Adequate maintenance access
• Protection from dust and moisture
• Suitable mounting support

The drive’s approximate weight is 14.5 kg, which should be considered when designing the mounting plate and cabinet structure.

Its approximate overall length is 781 mm, so cabinet height and cable-entry arrangements should be considered carefully.

---

21. Five Recommended Models from the Same PowerFlex 753 Series

The following five models are useful choices when the application requires the same general 690 V common-bus architecture but a different current or power capacity.

Model	Voltage	ND Current	ND Power	HD Current	HD Power	Frame	Approx. Weight	Approx. Dimensions
20F14NF012JN0NNNNN	690 VAC	12 A	7.5 kW	9 A	5.5 kW	6	14.5 kg	Approx. 781 × 250 × 300 mm
20F14NF020JN0NNNNN	690 VAC	20 A	15 kW	15 A	11 kW	6	Approx. 15–18 kg	Approx. Frame 6 envelope
20F14NF023JN0NNNNN	690 VAC	23 A	18.5 kW	20 A	15 kW	6	Approx. 16–20 kg	Approx. Frame 6 envelope
20F14NF030JN0NNNNN	690 VAC	30 A	22 kW	23 A	18.5 kW	6	Approx. 18–22 kg	Approx. Frame 6 envelope
20F14NF034JN0NNNNN	690 VAC	34 A	30 kW	30 A	22 kW	6	Approx. 20–25 kg	Approx. Frame 6 envelope

The 20F14NF012JN0NNNNN is the lower-capacity choice in this group.

The 20F14NF020JN0NNNNN provides a substantial increase in current capacity while maintaining the same general 690 V PowerFlex 753 common-bus concept.

The 20F14NF023JN0NNNNN, 20F14NF030JN0NNNNN and 20F14NF034JN0NNNNN can be considered when a larger motor or a higher-load machine requires additional capacity.

---

22. Same-Series Comparison

These models should not be considered direct drop-in replacements for the 20F14NF015JN0NNNNN.

The voltage class, input architecture, mounting dimensions, current rating and control-system requirements can be different.

They are included as related options for applications where the system architecture allows the use of another drive family.

---

24. PowerFlex 753 Versus PowerFlex 755

The PowerFlex 753 is well suited to general industrial applications and common-bus motor control.

The PowerFlex 755 is generally more appropriate when the application demands additional high-level functionality and more extensive system integration.

---

25. PowerFlex 525 as a Compact Alternative

The PowerFlex 525 family is a useful alternative when a smaller motor drive is required.

It is particularly suitable for:

• Small conveyors
• Small pumps
• Small fans
• Packaging machinery
• Small machine tools
• Compact automation equipment

Its physical size is much smaller than the Frame 6 20F14NF015JN0NNNNN.

However, the PowerFlex 525 is not a direct electrical replacement because it uses a different voltage and input architecture.

---

26. PowerFlex 40 as a General-Purpose Alternative

A PowerFlex 40-type drive can be considered for simpler motor-control applications.

It is particularly appropriate when the machine does not require the advanced common-bus architecture of the PowerFlex 753.

Typical applications include:

• Simple conveyors
• Fans
• Pumps
• Small processing equipment
• Basic speed-control applications

The smaller drive size can make cabinet installation easier.

---

27. Application Selection Guide

Medium 480 V machine	25B-D017N114	Higher compact-drive capacity
Large industrial machine	20G14ND0110JA0NNNNN	Higher-power drive family

The actual selection should be based on motor current, load profile and duty rather than simply matching the nominal motor kW value.

---

28. Advantages in Industrial Automation

The 20F14NF015JN0NNNNN is particularly useful in industrial automation because the drive can be integrated into a larger control system.

The machine controller can provide a speed reference and receive information about the operating state of the drive.

This allows the drive to participate in coordinated production sequences.

For example, a conveyor can start only after another machine reports that it is ready.

A pump can adjust its speed according to process conditions.

A fan can increase speed when ventilation demand rises.

A mixer can operate at different speeds during different stages of a production cycle.

This type of coordination is one of the major advantages of using an industrial drive rather than a simple motor starter.

---

29. Energy-Saving Potential

Energy savings depend heavily on the application.

For variable-torque loads such as pumps and fans, reducing speed can provide substantial energy savings.

For constant-torque applications such as conveyors and mixers, the main benefits are generally:

• Speed control
• Process control
• Soft starting
• Reduced mechanical shock
• Improved production consistency

Therefore, the energy-saving potential should be evaluated according to the actual motor load profile.

---

30. Dynamic Braking

The 20F14NF015JN0NNNNN does not include an internal dynamic-braking transistor.

This is important for machinery with high inertia.

When a motor decelerates, stored mechanical energy is returned toward the drive’s electrical system.

If the application requires rapid stopping, the energy must be managed appropriately.

Applications that may require special braking consideration include:

• High-inertia fans
• Centrifuges
• Rapid-stop conveyors
• Rollers
• Winders
• Unwinders
• High-speed machinery

If braking is required, the complete braking system should be designed according to the motor power, inertia, stopping time and operating frequency.

---

31. Cabinet Heat Management

Because the drive is air cooled, heat removal is an important part of the installation.

The cabinet should have sufficient ventilation to prevent excessive internal temperature.

The following should be considered:

• Ambient temperature
• Number of drives in the cabinet
• Drive losses
• Fan airflow
• Cabinet size
• Ventilation arrangement
• Dust accumulation
• Filter maintenance

If several drives are installed in the same enclosure, their combined heat generation should be considered rather than evaluating each drive separately.

---

32. Maintenance Advantages

The drive’s diagnostic capability can simplify maintenance.

Maintenance technicians can use drive information to investigate problems involving:

• Motor overload
• Excessive current
• Drive temperature
• DC-bus conditions
• Acceleration problems
• Deceleration problems
• Communication problems
• External interlocks
• Machine-load changes

This can reduce troubleshooting time because technicians can obtain information from the drive rather than relying only on physical inspection.

---

33. Recommended Spare-Parts Strategy

For a production facility using several PowerFlex 753 drives, a practical spare-parts strategy can include:

• One spare drive for critical machines
• Spare control components where appropriate
• Spare cooling components
• Spare communication modules when required
• Documented drive parameters
• Backup configuration files
• Motor nameplate information
• Cabinet wiring documentation

The exact strategy depends on machine criticality.

For a production line where one drive failure can stop the entire line, maintaining a suitable spare is often more valuable than waiting for a replacement after a failure occurs.

---

34. Replacement Considerations

37. Overall Product Evaluation

The 20F14NF015JN0NNNNN is a specialized industrial AC drive that combines a 690 VAC voltage class, 15 A output capacity, 11 kW Normal-Duty rating, 7.5 kW Heavy-Duty rating, Frame 6 construction, air cooling and a common-DC-bus input architecture.

Its greatest strength is not simply the 11 kW power rating.

The more important characteristic is the combination of medium-power motor capacity with a 690 V common-bus architecture.

This makes it especially suitable for industrial machines where multiple drive sections operate from a common DC system.

The filtered configuration and installed common-mode capacitor jumper make the exact electrical configuration important when selecting a replacement.

The absence of an internal dynamic-braking transistor is also an important consideration for machines requiring rapid deceleration.

The blank/no-HIM configuration makes the model well suited to automated equipment where the drive is controlled by a PLC, supervisory system or external operator interface.

38. Final Recommendation

For a 690 V common-bus application requiring approximately 11 kW Normal-Duty capacity, the 20F14NF015JN0NNNNN is a well-balanced PowerFlex 753 solution.

If the motor requires less capacity, the 20F14NF012JN0NNNNN is a logical lower-capacity option.

If more capacity is required, the 20F14NF020JN0NNNNN, 20F14NF023JN0NNNNN, 20F14NF030JN0NNNNN and 20F14NF034JN0NNNNN provide progressively higher current and power ratings.

For a different electrical architecture, the PowerFlex 525 family provides more compact solutions, while the PowerFlex 755 family is more suitable for larger and more sophisticated industrial drive systems.

The most important selection rule is to compare the motor nameplate current, duty classification, voltage, load characteristics, acceleration requirements, braking requirements and common-bus architecture.

The 11 kW rating should be treated as a reference rather than the only selection criterion.

40. Conclusion

The 20F14NF015JN0NNNNN is a medium-capacity, high-voltage industrial variable-frequency drive designed around the PowerFlex 753 platform.

Its 690 VAC three-phase rating, 15 A Normal-Duty output, 11 kW Normal-Duty capacity, 12 A Heavy-Duty output, 7.5 kW Heavy-Duty capacity, 932 VDC nominal common-bus input, Frame 6 construction and air-cooled open-type design make it a practical solution for a wide range of industrial motor-control applications.

The model is particularly attractive for machinery that already uses or is being designed around a common DC-bus system.

For pumps and fans, it provides adjustable speed and potential energy-saving benefits.

For conveyors and material-handling systems, it provides controlled acceleration and deceleration.

For mixers and process equipment, it provides adjustable motor speed and improved process control.

For automated production lines, its drive architecture can be integrated into a broader machine-control system.

Its approximate 14.5 kg weight and 781 mm length should be considered during cabinet design, transportation and installation.

The five most relevant same-series alternatives are 20F14NF012JN0NNNNN, 20F14NF020JN0NNNNN, 20F14NF023JN0NNNNN, 20F14NF030JN0NNNNN and 20F14NF034JN0NNNNN, which provide a useful progression of current and power capacity while maintaining the same general 690 V PowerFlex 753 common-bus concept.

For applications outside the 690 V common-bus architecture, smaller compact drive families or higher-performance large-drive families can be considered according to the machine requirements.

Overall, the 20F14NF015JN0NNNNN is best suited to industrial users who need a reliable 690 V, 15 A, 11 kW Normal-Duty common-bus AC drive with Frame 6 construction and flexible industrial motor-control capability.
