20F14NF098JN0NNNNN — Detailed Industrial AC Drive Product Profile, Technical Specifications, Applications, Advantages and Related Models

The 20F14NF098JN0NNNNN is a high-capacity industrial AC drive designed for large three-phase motor applications where reliable variable-speed control, substantial output capacity and flexible industrial integration are required.

It belongs to the PowerFlex 753 series and the broader PowerFlex 750-Series family. This particular configuration is designed for a 690 VAC, three-phase system, with a 98 A Normal Duty output rating, a 90 kW Normal Duty power rating, and a 75 kW Heavy Duty power rating.

The drive uses a Frame 6 construction and forced-air cooling. It is configured for DC input with precharge, uses a filtered configuration with the common-mode capacitor jumper installed, includes embedded I/O, and does not include an internal dynamic-braking transistor in this particular catalog configuration.

With its relatively high current capacity, the 20F14NF098JN0NNNNN is suitable for larger pumps, fans, blowers, conveyors, mixers, material-handling systems, rollers, process machinery and other industrial equipment requiring controlled AC motor operation.

The physical dimensions and weight should be treated as practical installation-planning values for the Frame 6 configuration.

For final cabinet fabrication, mounting, lifting and service-clearance calculations, the mechanical drawing associated with the actual supplied configuration should be used.

At approximately 38.6 kg, this is a substantial industrial drive. The mounting panel and cabinet structure should therefore be designed with appropriate mechanical support.

2. Brand and Product Series

Brand: Allen-Bradley.

Product Family: PowerFlex 750-Series.

Product Series: PowerFlex 753.

Product Type: Industrial AC Drive.

The 20F14NF098JN0NNNNN occupies an important position within the 690 VAC PowerFlex 753 range.

It is positioned above the 82 A configuration and below the 119 A configuration, providing 98 A Normal Duty current and 90 kW Normal Duty power.

Its Heavy Duty rating is 82 A and 75 kW, making it particularly useful for applications where substantial motor capacity and increased overload capability are required.

3. Product Introduction

The main purpose of the 20F14NF098JN0NNNNN is to control the speed and operating behavior of a three-phase AC motor.

Instead of supplying the motor with fixed-frequency power and allowing it to operate at essentially one normal speed, the drive controls the electrical conditions applied to the motor.

This allows motor speed to be adjusted according to the requirements of the machine.

That capability is valuable in industrial applications because the mechanical load is rarely constant.

A conveyor may need to accelerate slowly before reaching production speed.

A pump may need to operate at different flow rates.

A fan may need to adjust airflow.

A mixer may need a low-speed starting sequence before moving to its normal operating speed.

A production machine may require carefully controlled acceleration and deceleration.

The drive provides the electrical platform needed to manage these conditions.

4. Main Electrical Ratings

Electrical Parameter	Normal Duty	Heavy Duty
Model	20F14NF098JN0NNNNN	20F14NF098JN0NNNNN
Continuous Output Current	98 A	82 A
1-Minute Output Current	108 A	123 A
3-Second Output Current	147 A	148 A
Motor Power Rating	90 kW	75 kW
Voltage	690 VAC	690 VAC
Phase	3 Phase	3 Phase
Frame	Frame 6	Frame 6
Cooling	Forced Air	Forced Air

The 98 A Normal Duty rating is the key electrical specification.

It corresponds to a 90 kW Normal Duty motor-power rating.

For Heavy Duty applications, the drive is rated at 82 A continuous output current and 75 kW.

This distinction is important during drive selection.

A motor rated at 90 kW in a relatively stable load application may fit the Normal Duty rating.

A 90 kW motor operating under severe overload conditions would require a different evaluation because the Heavy Duty rating of this particular drive is 75 kW.

5. Normal Duty and Heavy Duty Ratings

The drive provides two principal duty classifications.

Duty Type	Continuous Current	1-Minute Current	3-Second Current	Power Rating
Normal Duty	98 A	108 A	147 A	90 kW
Heavy Duty	82 A	123 A	148 A	75 kW

Normal Duty is generally suitable for applications where the motor operates under a comparatively moderate load profile.

Heavy Duty is more appropriate where the motor experiences greater torque requirements or repeated overload conditions.

Examples can include:

• High starting torque.
• Frequent acceleration.
• Frequent deceleration.
• High mechanical inertia.
• Rapid load changes.
• Repeated short-duration overloads.
• Difficult starting conditions.
• High process torque.

The difference between the two ratings should always be considered when matching the drive to a motor.

6. 690 VAC Voltage Class

The 20F14NF098JN0NNNNN is designed for a 690 VAC, three-phase system.

This makes it particularly appropriate for larger industrial motor installations.

For a given amount of mechanical power, a higher motor voltage can reduce the current required compared with a lower-voltage system.

This can be useful when designing large industrial motor systems, particularly where cable sizing, switchgear and power-distribution considerations become significant.

7. DC Input with Precharge

This configuration uses DC input with precharge.

The nominal DC-bus class is approximately 932 VDC.

This characteristic makes the drive suitable for certain DC-bus and common-bus architectures.

The precharge system is important in high-power systems because the DC bus contains substantial capacitance.

A controlled charging process helps manage the initial current when the DC bus is energized.

This should be considered together with the overall power-distribution and protection strategy.

8. Frame 6 Construction

The drive uses a Frame 6 mechanical construction.

This is a large industrial drive frame designed for high-power applications.

For practical cabinet planning, the approximate dimensions are around:

665.5 mm high × 308 mm wide × 346.4 mm deep.

The approximate weight is:

38.6 kg.

Mechanical Parameter	Specification
Model	20F14NF098JN0NNNNN
Frame Size	Frame 6
Height	Approx. 665.5 mm
Width	Approx. 308 mm
Depth	Approx. 346.4 mm
Approx. Dimensions	Approx. 665.5 × 308 × 346.4 mm
Weight	Approx. 38.6 kg
Weight (kg)	Approx. 38.6 kg
Enclosure	IP00 / NEMA/UL Open Type
Cooling	Forced Air
Installation	Industrial Cabinet / Panel
Mounting Orientation	Vertical
Cabinet Ventilation	Required
Service Clearance	Required

The drive itself does not represent the entire cabinet footprint.

Additional room must normally be allowed for power cables, control wiring, ventilation, grounding, service access and other electrical equipment.

9. Enclosure Characteristics

The standard construction is IP00 / NEMA/UL Open Type.

This means the drive is normally installed inside an appropriate industrial electrical enclosure.

The enclosure should provide suitable protection against the surrounding environment and should also provide sufficient ventilation.

Environmental factors that should be considered include:

• Dust.
• Moisture.
• Chemical contamination.
• Ambient temperature.
• Vibration.
• Airflow.
• Electrical noise.
• Maintenance access.

Where required, an appropriate enclosure conversion can be considered for applicable Frame 6 configurations.

10. Forced-Air Cooling

The 20F14NF098JN0NNNNN uses forced-air cooling.

Because this is a 90 kW-class drive, thermal management is an important part of the installation.

A properly sized cabinet should provide a suitable airflow path around the drive.

Cooling Parameter	Consideration
Model	20F14NF098JN0NNNNN
Cooling Method	Forced Air
Cabinet Airflow	Required
Heat Dissipation	Must be considered
Airflow Path	Should remain unobstructed
Cooling Fan	Requires maintenance
Cabinet Temperature	Must remain within operating limits
Nearby Heat Sources	Should be considered
Ventilation	Required
Service Access	Required

A drive can be electrically suitable for a motor and still experience thermal problems if the cabinet environment is poorly designed.

For continuous operation, thermal design should therefore be considered from the beginning of the project.

11. Filtering Configuration

The catalog configuration specifies a filtered arrangement with the common-mode capacitor jumper installed.

This configuration is relevant to the electrical behavior of the drive and motor system.

Filtering can be important in applications where electromagnetic compatibility, motor-cable routing and electrical noise need to be managed carefully.

The drive’s grounding and cable installation should be designed consistently with the selected filtering arrangement.

12. Dynamic Braking Configuration

The 20F14NF098JN0NNNNN does not include an internal dynamic-braking transistor.

This is an important consideration for high-inertia machinery.

During deceleration, a motor can return mechanical energy toward the drive’s DC bus.

The more inertia and the faster the stopping requirement, the more significant this regenerative energy can become.

Applications that require special braking evaluation include:

• Large fans.
• Large conveyors.
• High-inertia rollers.
• Centrifuges.
• Rapid-cycle machinery.
• Large rotating equipment.
• Certain lifting systems.

The absence of an internal braking transistor does not prevent the drive from being used in these applications, but the overall braking architecture must be designed appropriately.

13. Product Application — Large Conveyor Systems

The 20F14NF098JN0NNNNN is well suited to large conveyor systems.

Large conveyors can require substantial starting torque, particularly when carrying heavy material.

A controlled acceleration profile can reduce mechanical shock and provide smoother machine operation.

Typical applications include:

• Mining conveyors.
• Bulk-material conveyors.
• Manufacturing conveyors.
• Packaging lines.
• Warehouse material handling.
• Transfer conveyors.
• Processing conveyors.
• Heavy industrial transportation systems.

For long conveyors, speed control can also help coordinate different sections of the production or material-handling system.

14. Product Application — Large Pumps

Large pumps are another important application.

Many industrial pumping systems do not need to operate continuously at maximum speed.

A variable-speed drive allows the motor speed to be adjusted according to process requirements.

Typical applications include:

• Industrial water pumps.
• Cooling-water systems.
• Process pumps.
• Circulation systems.
• Transfer pumps.
• Water-treatment equipment.
• Process-fluid systems.
• Industrial pumping stations.

For centrifugal pumps, variable-speed operation can be especially useful because pump performance changes substantially with motor speed.

15. Product Application — Industrial Fans

Large industrial fans can require significant motor power.

The 20F14NF098JN0NNNNN can control large fan motors while allowing the operating speed to be adjusted.

Typical applications include:

• Industrial ventilation.
• Factory exhaust.
• Furnace ventilation.
• Dust collection.
• Cooling systems.
• Air-handling systems.
• Process ventilation.
• Industrial air circulation.

Instead of running a fan continuously at maximum speed, the control system can adjust speed according to actual process demand.

16. Product Application — Large Blowers

Industrial blowers can also benefit from variable-speed operation.

A blower may need to maintain a specific airflow or pressure.

The drive can adjust the motor operating speed while the larger automation system controls the process.

Typical applications include:

• Pneumatic conveying.
• Industrial ventilation.
• Process air.
• Dust collection.
• Furnace systems.
• Combustion air.
• Industrial drying.
• Process equipment.

17. Product Application — Mixers and Agitators

Mixers and agitators can present variable mechanical loads.

The torque requirement may change as the material becomes thicker, more concentrated or more heavily loaded.

The drive provides a practical way to control the motor according to these changing requirements.

Potential applications include:

• Chemical processing.
• Food processing.
• Material preparation.
• Industrial mixing.
• Batch processing.
• Process tanks.
• Manufacturing systems.
• Production equipment.

If the mixer has a high breakaway torque or repeated overload condition, Heavy Duty selection should be evaluated carefully.

18. Product Application — Material Handling

Material-handling systems often benefit from controlled acceleration and deceleration.

The drive can be used for:

• Conveyors.
• Transfer systems.
• Rollers.
• Feed systems.
• Material movement.
• Production-line transportation.
• Industrial handling equipment.

For lifting and hoisting applications, additional engineering is required because braking, feedback and load-control requirements can be considerably more demanding than those of horizontal material-handling systems.

19. Product Application — Process Machinery

The PowerFlex 753 platform can also be used for many types of industrial process machinery.

Examples include:

• Production machinery.
• Rollers.
• Processing equipment.
• Packaging systems.
• Manufacturing machinery.
• Large auxiliary drives.
• Process lines.
• Industrial mechanical systems.

The modular drive architecture is especially useful when the machine requires more than basic speed control.

20. Product Advantages

20.1 High 98 A Output Capacity

The most obvious advantage of the 20F14NF098JN0NNNNN is its high output current.

The Normal Duty rating is 98 A.

This corresponds to 90 kW Normal Duty.

That makes the drive suitable for substantially larger motors than many compact industrial drives.

20.2 75 kW Heavy Duty Rating

The Heavy Duty rating is 82 A / 75 kW.

This is particularly valuable when the motor experiences higher mechanical loads.

For demanding 75 kW applications, this model can be a strong candidate, subject to the actual motor nameplate current and load profile.

20.3 690 VAC Compatibility

The 690 VAC voltage class makes the drive suitable for large industrial motor systems.

This can be particularly useful in installations where higher motor voltage is preferred for larger power levels.

20.4 Strong Short-Term Current Capability

The drive provides substantial short-duration current capability.

Duty	Continuous Current	1-Minute Current	3-Second Current
Normal Duty	98 A	108 A	147 A
Heavy Duty	82 A	123 A	148 A

This allows the drive to tolerate short periods of increased load within the applicable operating limits.

21. Modular Architecture

The PowerFlex 753 platform uses a modular architecture.

This is useful because industrial machines do not all require the same functions.

A basic machine may need:

• Start/stop.
• Speed reference.
• Fault indication.

A more advanced machine may additionally need:

• Encoder feedback.
• Industrial communication.
• Additional I/O.
• Safety functions.
• Process control.
• Advanced monitoring.

The modular approach allows the drive to be configured according to the application.

22. Embedded I/O

The drive includes embedded I/O.

This can simplify machine integration because basic control signals can be connected directly to the drive.

Depending on the overall system design, these signals can include:

• Start commands.
• Stop commands.
• Speed references.
• Status signals.
• Fault signals.
• Digital signals.
• Analog signals.

The exact I/O configuration should be checked against the actual machine-control requirements.

23. Communication Integration

The drive can form part of an industrial automation network through suitable communication options.

A typical architecture is:

PLC → Industrial Network → PowerFlex 753 Drive → Motor

An HMI can also be included:

HMI → PLC → Drive

This arrangement allows the drive to operate as part of a coordinated production system rather than as an isolated speed controller.

24. Feedback Capability

Some applications require better speed regulation than a basic open-loop system can provide.

Suitable feedback options can be used when the application requires more accurate motor-speed information.

Typical applications include:

• Encoder-based speed control.
• Synchronized machinery.
• Coordinated production lines.
• Precise process speed.
• Torque-sensitive systems.
• More demanding industrial machines.

25. Product Advantages for Machine Builders

The 20F14NF098JN0NNNNN can be attractive to machine builders because it combines high power with a flexible industrial platform.

A machine builder may have multiple machines with different motor sizes.

Using a drive family with multiple current levels makes it easier to standardize control architecture across machines.

The embedded I/O can simplify wiring.

Communication options can support PLC integration.

Feedback options can support more demanding applications.

The same general drive architecture can therefore be used across a range of machine sizes.

26. Product Advantages for Maintenance

Standardizing on a common drive platform can simplify maintenance.

Technicians can become familiar with:

• Drive parameters.
• Fault codes.
• Control architecture.
• Wiring practices.
• Communication methods.
• Preventive maintenance.
• Troubleshooting procedures.

This can reduce the amount of specialized training required when multiple machines use related drive configurations.

27. Product Advantages for System Integration

The 20F14NF098JN0NNNNN is not limited to simple motor-speed adjustment.

It can become part of a larger industrial automation architecture.

For example:

Operator → HMI → PLC → Network → Drive → Motor → Machine

Feedback can be added when necessary.

Safety equipment can be integrated into the overall control architecture.

Braking equipment can be added for high-inertia loads.

This makes the drive suitable for larger industrial control projects where several systems must work together.

30. Five Recommended Same-Series or Closely Related Models

The following models are useful alternatives because they are in the same PowerFlex 753 690 V range and provide nearby current and power levels.

Model	Series	Voltage	ND Current	ND Power	HD Current	HD Power	Frame	Cooling	Approx. Dimensions	Weight (kg)
20F14NF061JN0NNNNN	PowerFlex 753	690 VAC	61 A	55 kW	50 A	45 kW	6	Forced Air	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6

The 20F14NF061JN0NNNNN is the lower-capacity alternative in this group.

The 20F14NF082JN0NNNNN provides 75 kW Normal Duty.

The target 20F14NF098JN0NNNNN increases the Normal Duty rating to 90 kW.

The 20F14NF119JN0NNNNN increases the rating to 110 kW Normal Duty.

The 20F14NF142JN0NNNNN extends the range further to 132 kW Normal Duty.

31. Same-Series Electrical Comparison

Model	ND Continuous	ND 1-Minute	ND 3-Second	ND Power	HD Continuous	HD 1-Minute	HD 3-Second	HD Power
20F14NF061JN0NNNNN	61 A	67 A	92 A	55 kW	50 A	75 A	92 A	45 kW
20F14NF082JN0NNNNN	82 A	90 A	123 A	75 kW	61 A	92 A	123 A	55 kW
20F14NF098JN0NNNNN	98 A	108 A	147 A	90 kW	82 A	123 A	148 A	75 kW
20F14NF119JN0NNNNN	119 A	131 A	179 A	110 kW	98 A	147 A	179 A	90 kW
20F14NF142JN0NNNNN	142 A	156 A	213 A	132 kW	119 A	179 A	214 A	110 kW

This progression makes the position of the 20F14NF098JN0NNNNN particularly clear.

It provides the first 90 kW Normal Duty configuration in this group.

Its 75 kW Heavy Duty rating is also substantial enough for demanding large-motor applications.

32. Five Same-Brand Popular or Related Models

The following models are useful for comparing different drive families and power classes from the same brand.

Model	Series	Voltage Class	Current Class	Typical Power Class	Cooling	Construction	Approx. Dimensions	Weight (kg)
25B-D017N104	PowerFlex 525	480 VAC Class	17 A	Approx. 7.5 kW	Air Cooled	Compact	Approx. 200 × 300 × 180 mm	Approx. 5
25B-D024N104	PowerFlex 525	480 VAC Class	24 A	Approx. 11 kW	Air Cooled	Compact	Approx. 230 × 350 × 190 mm	Approx. 6–8
25B-D043N114	PowerFlex 525	480 VAC Class	43 A	Approx. 22 kW	Air Cooled	Compact / Larger Frame	Approx. 250 × 400 × 220 mm	Approx. 10–15
20F11NC043JA0NNNNN	PowerFlex 753	480 VAC Class	43 A	Approx. 22 kW	Air Cooled	Industrial	Approx. 250–300 × 500–700 × 300 mm	Approx. 30–45
20G11NC043JA0NNNNN	PowerFlex 755	480 VAC Class	43 A	Approx. 22 kW	Air Cooled	Industrial	Approx. 250–300 × 500–700 × 300 mm	Approx. 30–45

These five products should be viewed as related alternatives rather than direct replacements.

The voltage class is particularly important.

A 480 VAC drive cannot simply replace a 690 VAC drive because the motor voltage, drive rating, insulation requirements, current and electrical architecture must all be compatible.

33. Comparison with the 82 A Model

The difference between the 20F14NF082JN0NNNNN and the target model is important when choosing between adjacent drive sizes.

Parameter	20F14NF082JN0NNNNN	20F14NF098JN0NNNNN
Voltage	690 VAC	690 VAC
ND Continuous Current	82 A	98 A
ND Power	75 kW	90 kW
HD Continuous Current	61 A	82 A
HD Power	55 kW	75 kW
Frame	6	6
Cooling	Forced Air	Forced Air
Input	DC with Precharge	DC with Precharge
Dynamic Braking	None	None
Approx. Dimensions	665.5 × 308 × 346.4 mm	Approx. 665.5 × 308 × 346.4 mm
Weight (kg)	Approx. 38.6	Approx. 38.6

The move from the 82 A model to the 98 A model provides a significant capacity increase.

Normal Duty power increases from 75 kW to 90 kW.

Heavy Duty power increases from 55 kW to 75 kW.

This makes the target model particularly useful when the 82 A configuration is approaching its current or power limit.

34. Comparison with the 119 A Model

Parameter	20F14NF098JN0NNNNN	20F14NF119JN0NNNNN
Voltage	690 VAC	690 VAC
ND Current	98 A	119 A
ND Power	90 kW	110 kW
HD Current	82 A	98 A
HD Power	75 kW	90 kW
Frame	6	6
Cooling	Forced Air	Forced Air
Input	DC with Precharge	DC with Precharge
Dynamic Braking	None	None
Approx. Dimensions	665.5 × 308 × 346.4 mm	Frame 6 class
Weight (kg)	38.6	Approx. 38.6+

The 119 A model becomes the logical next step when the 98 A configuration is insufficient.

For a 90 kW Heavy Duty application, the 119 A configuration is especially relevant because its Heavy Duty rating reaches approximately 90 kW.

35. Motor Selection Considerations

Motor selection should always be based on more than the motor’s kW value.

The motor nameplate current is one of the most important parameters.

Motor Parameter	Selection Consideration
Motor Voltage	Must be compatible with the drive/system
Motor Current	Must fit within the selected duty rating
Motor Power	Compare with Normal Duty and Heavy Duty values
Motor Frequency	Verify compatibility
Motor Speed	Check required operating range
Starting Torque	Evaluate carefully
Continuous Torque	Consider thermal loading
Peak Torque	Compare with overload capability
Motor Type	Confirm supported control method
Feedback	Determine whether encoder feedback is required
Braking	Evaluate separately
Environment	Consider temperature, dust, moisture and vibration

For a 90 kW Normal Duty motor, the 20F14NF098JN0NNNNN is a logical drive to evaluate.

For a 90 kW Heavy Duty motor, however, this particular drive is not the appropriate capacity because its Heavy Duty rating is 75 kW.

A larger drive should be considered for that application.

36. Application Selection by Duty

Application Type	Typical Selection Consideration
Large centrifugal pump	Normal Duty may be appropriate depending on load
Large fan	Normal Duty may be appropriate
Industrial blower	Depends on load profile
Conveyor	Evaluate starting and acceleration torque
Heavy conveyor	Heavy Duty may be required
Mixer	Evaluate breakaway torque
Agitator	Evaluate torque profile
Large roller	Evaluate inertia and braking
Process machine	Evaluate continuous and peak torque
Hoist	Requires dedicated braking and safety evaluation
High-inertia machine	Braking system requires detailed evaluation
Rapid-cycle machine	Heavy Duty and thermal performance should be evaluated

37. Typical Industrial Control Architecture

A typical installation can be structured as:

PLC / Controller → Industrial Network → PowerFlex 753 Drive → Three-Phase Motor → Mechanical Load

Additional control equipment can include:

HMI → PLC → Drive

and:

Encoder → Feedback Interface → Drive

Other equipment can include:

• Circuit breakers.
• Disconnects.
• Motor protection.
• Safety equipment.
• Braking equipment.
• Control transformers.
• Cabinet cooling.
• Industrial communication equipment.
• Additional drives.

This architecture allows the drive to become an integrated component of the machine-control system.

The PowerFlex 755 family becomes more attractive when the application requires a higher level of advanced control functionality.

45. Model Number Configuration

The catalog number 20F14NF098JN0NNNNN contains several configuration characteristics.

The model identifies the PowerFlex 753 family, the 690 V class, the 98 A output class and the Frame 6 construction.

The J configuration indicates the specified filtering/common-mode capacitor jumper arrangement.

The relevant N configuration indicates that an internal dynamic-braking transistor is not installed.

This is important because braking and filtering configuration can affect how the drive is integrated into a complete machine.

46. Why the 20F14NF098JN0NNNNN Is a Strong Choice

The strongest reason to select this model is its combination of 90 kW Normal Duty and 75 kW Heavy Duty capacity.

This gives the drive a useful operating range for larger industrial motors.

The 690 VAC voltage class is another major advantage.

The Frame 6 construction provides a substantial industrial platform.

The forced-air cooling system is suitable for the high power level when the cabinet is properly designed.

The embedded I/O provides a practical starting point for machine integration.

The modular architecture provides room for additional functions.

Communication and feedback options make the drive suitable for more sophisticated control systems.

47. Overall Product Evaluation

The 20F14NF098JN0NNNNN is a high-power industrial AC drive intended for large three-phase motor applications.

Its primary electrical ratings are 690 VAC, 98 A Normal Duty, 90 kW Normal Duty, 82 A Heavy Duty and 75 kW Heavy Duty.

This makes it particularly suitable for large industrial machinery where a compact inverter would not provide sufficient current or power capacity.

The drive is well suited to large pumps, fans, blowers, conveyors, mixers, rollers, process machinery and material-handling equipment.

Its 90 kW Normal Duty rating is especially useful for larger motors operating under moderate and relatively stable load conditions.

Its 75 kW Heavy Duty rating provides substantial capacity for applications with greater overload requirements.

The distinction between these ratings is important and should be considered carefully during final drive selection.

The 690 VAC voltage class makes the model appropriate for larger industrial motor systems.

Its Frame 6 mechanical construction provides a substantial industrial platform, but it also means that cabinet dimensions, mounting strength and thermal management must be carefully considered.

The approximate dimensions are 665.5 × 308 × 346.4 mm, with an approximate weight of 38.6 kg.

Because the drive uses an open-type construction, it should normally be installed inside an appropriately designed electrical enclosure.

Forced-air cooling also requires adequate cabinet ventilation and maintenance access.

The specific configuration does not include an internal dynamic-braking transistor.

Therefore, machines with high inertia or rapid stopping requirements should be evaluated separately for braking requirements.

The modular PowerFlex 753 architecture is another major advantage.

The drive can be used for straightforward variable-speed applications, but it can also participate in larger automation systems involving PLCs, HMIs, industrial networks, feedback devices and additional I/O.

Within the 690 V PowerFlex 753 range, the 20F14NF098JN0NNNNN occupies a particularly useful position.

The 20F14NF082JN0NNNNN provides a lower 75 kW Normal Duty rating.

The target model raises that capability to 90 kW Normal Duty.

The 20F14NF119JN0NNNNN then increases the Normal Duty rating to approximately 110 kW.

This makes the product family convenient when an industrial project includes motors of several different sizes.

In practical terms, the 20F14NF098JN0NNNNN can be summarized as a 690 VAC, three-phase, 98 A, 90 kW Normal Duty / 75 kW Heavy Duty, Frame 6 industrial AC drive with forced-air cooling, DC input with precharge, filtered configuration, common-mode capacitor jumper installed, embedded I/O and modular PowerFlex 753 architecture.

It is particularly well suited to large industrial pumps, fans, blowers, conveyors, material-handling equipment, mixers, rollers, process machinery and other high-power motor-driven systems where controlled speed, controlled acceleration, industrial automation integration and flexible drive configuration are important requirements.
