Allen-Bradley 20F14NF142JN0NNNNN — Detailed Product Specifications, Introduction, Applications, Advantages and Related Models

The 20F14NF142JN0NNNNN is a high-power industrial AC drive from the PowerFlex 753 series. It is designed for large three-phase motor applications where high output current, substantial motor power, adjustable speed, controlled acceleration, reliable process operation and industrial automation integration are required.

This model is a 690 VAC, three-phase PowerFlex 753 AC drive with a 142 A output rating. It provides a 132 kW Normal Duty rating and a 110 kW Heavy Duty rating, placing it toward the upper end of the 690 VAC PowerFlex 753 range.

The drive uses a Frame 6 mechanical construction and forced-air cooling. The specified configuration uses DC input with precharge, filtered operation, the common-mode capacitor jumper installed, embedded I/O, standard protection and a blank/no-HIM configuration.

The catalog number also indicates no internal dynamic-braking transistor. This is an important point when comparing the unit with closely related configurations that include a braking transistor.

The 20F14NF142JN0NNNNN is intended for large industrial equipment such as pumps, fans, blowers, conveyors, mixers, rollers, material-handling systems and process machinery.

Because of its 142 A rating and 132 kW Normal Duty capability, this model is particularly appropriate when a smaller 690 VAC drive is no longer sufficient but the application remains within the PowerFlex 753 690 VAC power range.

The approximate mechanical envelope of 665.5 × 308 × 346.4 mm is useful for preliminary cabinet planning, but the actual mechanical drawing should be used before finalizing mounting holes, cable-entry positions and service clearances.

2. Brand and Product Series

Brand: Allen-Bradley.

Product Family: PowerFlex 750-Series.

Product Series: PowerFlex 753.

The PowerFlex 753 series is an industrial architecture-class AC drive family designed for machine builders, system integrators and industrial plants that require more flexibility than a basic compact variable-frequency drive.

The series combines high-power motor control with embedded I/O and an expandable architecture.

The 20F14NF142JN0NNNNN represents one of the larger 690 VAC configurations in the PowerFlex 753 family.

Its combination of 142 A current capacity, 132 kW Normal Duty power and 110 kW Heavy Duty power makes it suitable for large industrial motor applications.

3. Product Introduction

The main function of the 20F14NF142JN0NNNNN is to control the speed and operation of a large three-phase AC motor.

A conventional motor connected directly to the power supply generally operates at a speed determined by the supply frequency and motor characteristics.

A variable-frequency drive changes the electrical conditions supplied to the motor so that motor speed can be adjusted according to the machine’s requirements.

This is especially valuable in industrial equipment because the required motor speed often changes during production.

A pump may need a lower speed when process demand decreases.

A fan may require different airflow at different production stages.

A conveyor may need controlled acceleration before reaching its production speed.

A mixer may need one speed during startup and another speed during processing.

A roller may need accurate speed control to maintain synchronization with other machinery.

The drive therefore acts as an important link between the industrial controller, the electrical power system and the motor.

4. Main Electrical Ratings

Electrical Parameter	Normal Duty	Heavy Duty
Model	20F14NF142JN0NNNNN	20F14NF142JN0NNNNN
Continuous Output Current	142 A	110 A
Power Rating	132 kW	110 kW
Voltage	690 VAC	690 VAC
Phase	3 Phase	3 Phase
Frame	Frame 6	Frame 6
Cooling	Forced Air	Forced Air
Input	DC Input with Precharge	DC Input with Precharge
Dynamic Braking	None	None

The 142 A Normal Duty rating is the main electrical characteristic of this model.

At Normal Duty, the drive is rated for 132 kW.

For Heavy Duty operation, the continuous current rating is 110 A, corresponding to a 110 kW Heavy Duty rating.

This distinction is important because motor selection should be based on both the motor nameplate current and the actual mechanical load profile.

5. Normal Duty Operation

The 132 kW Normal Duty rating makes this drive appropriate for large industrial motors operating under relatively moderate overload conditions.

Typical Normal Duty applications include:

• Large centrifugal pumps.
• Large industrial fans.
• Cooling-water systems.
• Large blowers.
• Continuous conveyors.
• Circulation systems.
• Process equipment with relatively stable torque.
• Large material-handling systems.

Normal Duty does not mean that the drive cannot handle transient load changes.

It means that the application should be evaluated against the Normal Duty rating and its applicable overload characteristics rather than against the Heavy Duty rating.

6. Heavy Duty Operation

The Heavy Duty rating is 110 A / 110 kW.

Heavy Duty selection is important for applications that demand greater torque or experience more demanding operating cycles.

Typical Heavy Duty applications may include:

• Heavy conveyors.
• Mixers.
• Agitators.
• High-inertia machinery.
• Machines with difficult starting conditions.
• Equipment with frequent acceleration.
• Equipment with repeated load changes.
• Industrial process machinery.

For a 110 kW Heavy Duty motor, this model provides a useful capacity level when the actual motor nameplate current remains within the drive’s applicable rating.

7. 690 VAC Three-Phase Operation

The 20F14NF142JN0NNNNN is designed for a 690 VAC, three-phase electrical system.

This voltage class is particularly useful in large industrial installations.

When motor power increases, electrical current becomes a major design consideration.

A higher motor voltage can allow large amounts of power to be transferred with less current than would be required at a lower voltage.

This can influence:

• Motor cable sizing.
• Switchgear selection.
• Power distribution.
• Cabinet layout.
• Protection equipment.
• Motor selection.
• System losses.
• Electrical installation cost.

For this reason, the 690 VAC configuration is especially relevant to large motors and heavy industrial equipment.

8. DC Input with Precharge

The drive is configured for DC input with precharge.

The associated DC-bus class is approximately 932 VDC.

A DC-bus configuration can be useful in industrial systems where several drives or power-conversion devices are connected through a common DC architecture.

The precharge function is important because the DC bus contains substantial capacitance.

When the system is energized, the precharge process controls the initial charging behavior of the DC bus.

This becomes increasingly important in large industrial systems where several high-power devices may be connected to the same electrical infrastructure.

9. Dynamic Braking Configuration

The 20F14NF142JN0NNNNN has no internal dynamic-braking transistor.

This is one of the most important configuration characteristics of the model.

The absence of an internal braking transistor does not prevent the drive from being used in every application involving deceleration.

It simply means that the internal braking transistor is not included in this particular configuration.

Where substantial regenerative energy must be dissipated, the braking architecture needs to be designed separately.

10. Comparison with a Braking-Enabled Configuration

A closely related configuration can have the same general voltage, current and power class while adding an internal dynamic-braking transistor.

Feature	20F14NF142JN0NNNNN	Braking-Enabled 142 A Configuration
Voltage	690 VAC	690 VAC
Normal Duty Current	142 A	142 A
Normal Duty Power	132 kW	132 kW
Heavy Duty Current	110 A	110 A
Heavy Duty Power	110 kW	110 kW
Frame	6	6
Cooling	Forced Air	Forced Air
Input	DC + Precharge	Configuration dependent
Filtering	Filtered	Filtered
CM Jumper	Installed	Installed
Internal DB Transistor	None	Available in suitable configuration
HIM	Blank / No HIM	Configuration dependent

The major difference is therefore not the basic motor-power rating.

It is the braking configuration.

This distinction should be considered during engineering rather than after the drive has already been installed.

11. High-Inertia Application Considerations

Large industrial machines can store significant kinetic energy.

Examples include:

• Large fans.
• Heavy rollers.
• Large conveyors.
• Centrifuges.
• Large rotating drums.
• Flywheel-type machinery.

When such equipment decelerates, the stored mechanical energy can return toward the drive’s DC bus.

If the energy causes the DC-bus voltage to rise beyond the appropriate operating range, the system needs a suitable method of managing the energy.

Depending on the application, this may involve:

• Controlled deceleration.
• Regenerative solutions.
• External braking equipment.
• Appropriate braking resistors.
• Longer stopping times.
• Mechanical braking systems.

Because the target model has no internal dynamic-braking transistor, these considerations are particularly important for high-inertia machinery.

12. Frame 6 Mechanical Construction

The drive uses a Frame 6 design.

Frame 6 is intended for large industrial applications and provides the physical platform required for this level of electrical capacity.

The approximate physical envelope is:

Height: 665.5 mm.

Width: 308 mm.

Depth: 346.4 mm.

Approximate dimensions: 665.5 × 308 × 346.4 mm.

Net weight: approximately 38.555 kg.

Mechanical Parameter	Specification
Model	20F14NF142JN0NNNNN
Frame	Frame 6
Height	Approx. 665.5 mm
Width	Approx. 308 mm
Depth	Approx. 346.4 mm
Dimensions	Approx. 665.5 × 308 × 346.4 mm
Net Product Weight	Approx. 38.555 kg
Weight (kg)	Approx. 38.555 kg
Enclosure	Open Type
Cooling	Forced Air
Installation	Industrial Cabinet
Mounting	Panel / Cabinet
Ventilation	Required
Service Clearance	Required

The cabinet should not be designed around the drive dimensions alone.

Additional space is required for:

• Incoming power cables.
• Motor cables.
• Control wiring.
• Communication wiring.
• Grounding.
• Ventilation.
• Maintenance.
• Inspection.
• Service access.

13. Open-Type Enclosure

The product uses an Open Type construction.

Frame 6 drives of this type are normally integrated into an appropriately designed industrial enclosure or control cabinet.

The enclosure should provide protection against the surrounding environment.

Potential environmental concerns include:

• Dust.
• Moisture.
• Oil mist.
• Chemical contamination.
• Excessive temperature.
• Mechanical impact.
• Unwanted foreign objects.

The enclosure should also be designed to maintain the required airflow around the drive.

14. Forced-Air Cooling

The 20F14NF142JN0NNNNN uses forced-air cooling.

At 132 kW Normal Duty, thermal management is a major engineering consideration.

The cabinet needs a suitable airflow path.

Cooling fans and ventilation openings should be kept clear.

Filters should be maintained when the cabinet uses filtered air.

Cooling Parameter	Consideration
Model	20F14NF142JN0NNNNN
Cooling Method	Forced Air
Cabinet Ventilation	Required
Airflow	Must remain unobstructed
Cooling Fans	Preventive maintenance required
Cabinet Temperature	Must remain within allowable limits
Heat Dissipation	Must be considered
Air Filters	Inspect and maintain where applicable
Nearby Heat Sources	Must be considered
Service Access	Required

High-power drives should never be treated as though they generate negligible heat.

The cabinet’s thermal design should be completed before final installation.

15. Filtering and Common-Mode Capacitor Configuration

The model uses a filtered configuration with the common-mode capacitor jumper installed.

This configuration affects the drive’s electrical characteristics and should be considered as part of the complete installation.

The engineering design should include:

• Grounding.
• Motor-cable routing.
• Shielding.
• Cable length.
• Separation between power and control wiring.
• Cabinet grounding.
• Motor insulation.
• Electrical-noise considerations.

Correct cable installation can be particularly important when a high-power variable-frequency drive is installed close to sensitive control equipment.

16. Embedded I/O

The PowerFlex 753 platform includes embedded I/O.

This allows the drive to handle a variety of common control signals without requiring every signal to pass through separate external interface equipment.

Typical functions may include:

• Start.
• Stop.
• Enable.
• Speed reference.
• Fault indication.
• Drive status.
• Digital commands.
• Analog signals.

Embedded I/O can help simplify machine wiring and reduce the amount of additional control hardware required for basic drive functions.

17. Communication and Automation Integration

The PowerFlex 753 architecture can be integrated into a broader industrial control system using suitable communication options.

A typical arrangement can be:

PLC → Industrial Network → PowerFlex 753 → Motor

A more complete system can include:

HMI → PLC → Network → Drive → Motor

The drive can then become part of a coordinated production system.

Typical information exchanged with the control system can include:

• Speed reference.
• Actual speed.
• Run status.
• Fault status.
• Current.
• Operating condition.
• Control commands.
• Diagnostic information.

This makes the drive useful for automated manufacturing and process systems.

18. Motor-Control Capability

The PowerFlex 753 platform is designed for flexible motor control.

Depending on the application and selected options, the platform can support control methods such as:

• Volts-per-Hertz control.
• Sensorless vector control.
• Vector control.
• Encoder-based feedback control.
• Speed regulation.
• Torque-oriented control.

This flexibility is useful because not every machine has the same motor-control requirements.

A simple centrifugal fan may need straightforward variable-speed operation.

A large conveyor may require more precise acceleration and speed regulation.

A production roller may require feedback and coordination with other drives.

19. Product Application — Large Pumps

Large pumps are a natural application for the 20F14NF142JN0NNNNN.

Industrial pumping systems often operate under changing process conditions.

The drive can adjust motor speed according to the required process flow.

Potential applications include:

• Cooling-water pumps.
• Industrial water pumps.
• Process-fluid pumps.
• Transfer pumps.
• Circulation systems.
• Water-treatment equipment.
• Industrial utility systems.
• Large process pumps.

Variable-speed control can also provide smoother startup than direct-on-line motor starting.

20. Product Application — Large Fans

Large industrial fans can require significant motor power, especially when operating continuously.

The drive can vary fan speed according to actual ventilation demand.

Applications can include:

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

The ability to reduce motor speed when full airflow is not required can be valuable in variable-demand systems.

21. Product Application — Large Blowers

Industrial blowers often require controlled airflow and pressure.

The drive can provide adjustable blower speed while the larger control system manages the process.

Typical applications include:

• Pneumatic conveying.
• Process air.
• Industrial drying.
• Dust collection.
• Combustion air.
• Furnace systems.
• Chemical processing.
• Manufacturing processes.

The actual blower torque curve should be checked before selecting Normal Duty or Heavy Duty operation.

• Easier integration with other production equipment.

Potential applications include:

• Mining.
• Bulk material handling.
• Manufacturing.
• Warehousing.
• Processing plants.
• Transfer systems.
• Heavy industrial logistics.

For high-inertia conveyors, the braking system should receive special attention because this configuration does not contain an internal dynamic-braking transistor.

23. Product Application — Rollers

Large industrial rollers often require stable and repeatable speed control.

Examples include:

• Steel-processing rollers.
• Paper-processing equipment.
• Printing lines.
• Packaging equipment.

The material inside the tank or vessel may also change the load during operation.

The drive can provide controlled acceleration and adjustable speed.

Applications include:

• Chemical processing.
• Food processing.
• Batch production.
• Material preparation.
• Industrial tanks.
• Process machinery.
• Manufacturing.

For machines with particularly high breakaway torque, Heavy Duty selection should be evaluated carefully.

25. Product Application — Process Machinery

Examples include:

• Production lines.
• Processing equipment.
• Packaging machinery.
• Manufacturing systems.
• Material-processing equipment.
• Large auxiliary machinery.
• Industrial production equipment.

Its modular architecture makes it useful when the machine needs more than basic speed control.

26. Product Application — Material Handling

Material-handling systems often use multiple motors and multiple drives.

The PowerFlex 753 architecture can be useful in these installations because each drive can be integrated into a larger control system.

Applications may include:

• Transfer conveyors.
• Heavy-duty conveyors.
• Sorting systems.
• Bulk-material systems.
• Production-line transport.
• Warehouse handling equipment.

Coordination between drives can be important when several motors operate as part of the same mechanical process.

This comparison illustrates an important selection issue.

The target 142 A model provides higher electrical capacity.

The 119 A JA model provides lower electrical capacity but includes an internal dynamic-braking transistor.

Therefore, the correct choice depends on both motor requirements and braking requirements.

A higher-current drive is not automatically the best choice if the machine requires a specific braking configuration.

39. Motor Selection Considerations

Motor selection should always begin with the actual motor nameplate.

Important parameters include:

Motor Parameter	Selection Consideration
Motor Voltage	Must be suitable for the 690 VAC system
Motor Current	Must remain within the applicable drive rating
Motor Power	Compare against 132 kW ND / 110 kW HD
Motor Frequency	Verify operating requirements
Motor Speed	Check required speed range
Starting Torque	Evaluate carefully
Continuous Torque	Check thermal requirements
Peak Torque	Check overload requirements
Motor Type	Confirm compatibility
Feedback	Determine whether encoder feedback is needed
Braking	Evaluate regenerative energy
Motor Cable	Consider cable length
Environment	Consider temperature, dust, moisture and vibration

A 132 kW Normal Duty motor can be considered with this drive when the actual motor current and load profile are within the applicable rating.

A 110 kW Heavy Duty motor can also be considered where the current requirement remains within the Heavy Duty rating.

40. Application Selection Guide

Application	Suitability	Main Consideration
Large centrifugal pump	Excellent	Normal Duty
Large industrial fan	Excellent	Speed regulation
Large blower	Excellent	Process airflow
Large conveyor	Excellent	Starting torque and braking
Large roller	Excellent	Speed and inertia
Mixer	Very Good	Breakaway torque
Agitator	Very Good	Torque profile
Process machinery	Excellent	Communication and control
Material handling	Excellent	Acceleration/deceleration
High-inertia machinery	Good with suitable braking architecture	Regenerative energy
Rapid-cycle equipment	Application dependent	Braking and thermal duty
Large production machinery	Excellent	System integration

41. Typical Industrial Control Architecture

A typical system can be arranged as:

PLC / Controller → Industrial Network → PowerFlex 753 → Motor → Machine

A more complete system can include:

HMI → PLC → Industrial Network → Drive → Motor

Feedback can be added where required:

Encoder → Feedback Interface → Drive

For a machine requiring braking, an appropriate external braking architecture can be evaluated because the target configuration does not include an internal dynamic-braking transistor.

42. Typical Industries

Industry	Typical Application
Mining	Large conveyors and material handling
Metals	Rollers and processing machinery
Paper	Rollers and production lines
Water Treatment	Large pumps
Chemical Processing	Pumps and mixers
Manufacturing	Large production equipment
Food Processing	Mixers and conveyors
Industrial HVAC	Fans and blowers
Utilities	Pumps and auxiliary systems
Material Handling	Conveyors and transfer systems
General Process Industry	Pumps, fans, blowers and mixers

43. Installation Considerations

The physical size of the drive should be considered during cabinet design.

The approximate Frame 6 dimensions are:

665.5 mm × 308 mm × 346.4 mm.

The net product weight is approximately:

38.555 kg.

The cabinet must provide adequate support and sufficient clearance.

Electrical connections should be planned before the cabinet is fabricated.

The following areas should be considered:

• Incoming power.
• Motor output.
• DC-bus connections.
• Control wiring.
• Communication wiring.
• Grounding.
• Ventilation.
• Maintenance access.
• Braking equipment where applicable.

The drive should not be installed in a cabinet where airflow is restricted.

The heat generated during continuous operation needs to be included in the cabinet thermal calculation.

44. Maintenance Considerations

Regular maintenance should include inspection of:

• Cooling fans.
• Airflow openings.
• Cabinet filters.
• Power terminals.
• Grounding connections.
• Motor cables.
• Control wiring.
• Communication connections.
• Fault history.
• Cabinet temperature.

Dust accumulation can reduce airflow.

Loose electrical connections can increase resistance and heat.

A dirty cooling system can result in higher operating temperatures.

For high-power equipment, preventive maintenance can therefore have a direct impact on long-term reliability.

50. Catalog Number Configuration

The catalog number 20F14NF142JN0NNNNN contains several important configuration details.

The product belongs to the PowerFlex 753 family.

The voltage class is 690 VAC.

The 142 designation identifies the 142 A current class.

The drive uses DC input with precharge.

The unit is configured as an open-type, air-cooled drive.

The filtering configuration is filtered with the common-mode capacitor jumper installed.

The dynamic-braking configuration is none.

The HIM configuration is blank/no HIM.

The remaining configuration positions represent the specified option selections for this particular catalog number.

51. Why the 142 A Model Is Useful

The 142 A model is particularly useful when a motor application has outgrown the 119 A configuration.

The difference is not merely a small increase in current.

The Normal Duty power rating increases from 110 kW to 132 kW.

The Heavy Duty power rating increases from 90 kW to 110 kW.

This can make the 142 A model a practical step for large industrial equipment where the 119 A model is approaching its rating.

52. When the 119 A Model May Still Be Better

A larger drive is not automatically a better drive.

If the motor current is comfortably below the 119 A rating and the application does not require additional capacity, the smaller model may be more economical and may provide sufficient performance.

The 142 A model becomes more attractive when:

• Motor current approaches 119 A.
• Motor power is around 132 kW.
• Heavy Duty operation approaches 110 kW.
• The load requires additional current margin.
• Future capacity expansion is anticipated.
• The application has demanding operating conditions.

The final selection should always be based on the actual motor nameplate and load profile.

53. When an Alternative Braking Configuration Should Be Considered

The target model has no internal dynamic-braking transistor.

A braking-enabled configuration should be considered when the application requires:

• Rapid stopping.
• High braking torque.
• Frequent deceleration.
• High-inertia load management.
• Controlled stopping of large rotating equipment.
• Significant regenerative-energy dissipation.

For applications where the motor normally accelerates slowly and coasts to a stop, the lack of an internal braking transistor may not be a problem.

The machine’s actual stopping requirements should determine the correct configuration.

54. Recommended Selection by Application

Around 132 kW Normal Duty	20F14NF142JN0NNNNN
Around 110 kW Heavy Duty	20F14NF142JN0NNNNN
High-inertia application requiring integrated DB transistor	Consider braking-enabled configuration
Larger than 132 kW ND	Consider higher-capacity drive class

55. Overall Product Evaluation

The 20F14NF142JN0NNNNN is a high-capacity industrial AC drive designed for large three-phase motor applications.

Its primary electrical rating is 142 A Normal Duty, corresponding to 132 kW Normal Duty.

Its Heavy Duty rating is 110 A / 110 kW.

This makes it a substantial step above the 119 A / 110 kW Normal Duty configuration.

The 690 VAC three-phase design makes the drive suitable for large industrial motor systems where high-power operation and appropriate electrical distribution architecture are required.

The Frame 6 mechanical design provides a large industrial platform.

The approximate dimensions are 665.5 × 308 × 346.4 mm, with a net product weight of approximately 38.555 kg.

The drive is forced-air cooled, so cabinet ventilation and thermal management are important.

The open-type construction also means that suitable enclosure protection should be provided as part of the overall installation.

The DC input with precharge configuration makes the drive useful for applications involving DC-bus or common-bus power architectures.

The filtered configuration and common-mode capacitor jumper setting should be considered when designing the complete electrical system.

The embedded I/O provides a practical interface for machine control.

Communication and feedback options can extend the drive’s capabilities and allow it to become part of a larger industrial automation system.

One important limitation of the exact 20F14NF142JN0NNNNN configuration is that it has no internal dynamic-braking transistor.

This does not prevent the drive from being used in many industrial applications.

For pumps, fans and other equipment that does not require aggressive braking, this configuration can be perfectly appropriate.

For large high-inertia equipment requiring frequent and rapid deceleration, the braking architecture should be evaluated carefully.

A braking-enabled configuration may be more suitable in those cases.

The PowerFlex 753 platform is especially attractive for large industrial machines because it combines high-power motor control with an expandable architecture.

The drive can be used for pumps, fans, blowers, conveyors, rollers, mixers, material-handling equipment and process machinery.

For a 132 kW Normal Duty motor, this model is a natural candidate when the motor nameplate current and application duty are compatible with the 142 A rating.

For a 110 kW Heavy Duty motor, it also provides an appropriate high-power class when the actual current requirements are within the Heavy Duty rating.

In practical terms, the product can be summarized as a 690 VAC, three-phase, 142 A, 132 kW Normal Duty / 110 kW Heavy Duty, Frame 6, forced-air-cooled PowerFlex 753 industrial AC drive with DC input and precharge, filtered configuration, common-mode capacitor jumper installed, embedded I/O, standard protection, blank/no-HIM configuration and no internal dynamic-braking transistor.

Its high current capacity, high motor-power rating, 690 VAC compatibility, modular industrial architecture and automation-integration capability make it a strong choice for large industrial motor systems where dependable variable-speed control is required.

For applications around 132 kW Normal Duty or 110 kW Heavy Duty, the 20F14NF142JN0NNNNN provides a particularly useful combination of capacity and industrial control functionality.

The most important points to remember when selecting this model are the 142 A current rating, 132 kW Normal Duty rating, 110 kW Heavy Duty rating, 690 VAC three-phase input class, Frame 6 construction, forced-air cooling, approximately 665.5 × 308 × 346.4 mm physical envelope, approximately 38.555 kg net product weight, DC input with precharge, filtered configuration, and absence of an internal dynamic-braking transistor.
