Allen-Bradley 20G14NF098JA0NNNNN PowerFlex 755 AC Drive – Detailed Product Guide

1. Product Overview

The 20G14NF098JA0NNNNN is an Allen-Bradley PowerFlex 755 AC Drive designed for high-power industrial motor-control applications. It is an air-cooled, open-type drive intended for integration into industrial control cabinets, machine-control systems, process equipment, and larger automated production systems.

This model is part of the PowerFlex 755 series and belongs to the broader PowerFlex 750-Series platform. It is designed for three-phase 690 VAC systems and provides a 98 A Normal Duty output rating, with a Normal Duty motor rating of approximately 90 kW. Its Heavy Duty rating is approximately 75 kW at 82 A.

The drive uses a DC input with precharge, making it suitable for power architectures where a DC bus or common-bus arrangement is required. The model is also configured as an air-cooled Frame 6 open-type drive, with filtering and the CM jumper installed.

The complete configuration includes a DB transistor, while the local operator interface is specified as Blank / No HIM. The configuration is therefore well suited to centralized automation systems in which the drive is managed through a PLC, HMI, supervisory system, or industrial communication network rather than through a permanently mounted local keypad.

---

4. Electrical Rating

The 20G14NF098JA0NNNNN is a relatively high-power drive within the 690 VAC PowerFlex 755 range.

Its Normal Duty rating is:

98 A / 90 kW

Its Heavy Duty rating is:

82 A / 75 kW

This distinction is important when selecting the drive for an actual motor.

A motor should not be selected solely by comparing its kW rating with the drive’s kW rating. The motor’s rated current, load type, acceleration requirements, overload requirements, operating speed, and environmental conditions all need to be considered.

For example, a 90 kW motor used on a relatively smooth centrifugal pump application may have very different requirements from a 90 kW motor driving a high-inertia conveyor or heavily loaded process machine.

---

5. Normal Duty vs. Heavy Duty

Rating	Current	Motor Power	Typical Load Type
20G14NF098JA0NNNNN – Normal Duty	98 A	90 kW	Fans, pumps, blowers, conveyors and general industrial loads
20G14NF098JA0NNNNN – Heavy Duty	82 A	75 kW	More demanding loads with higher overload requirements

Normal Duty applications generally involve loads whose torque requirement follows a relatively moderate operating profile.

Heavy Duty applications normally require more consideration because acceleration, overload, torque production, and thermal loading can be more demanding.

For final drive sizing, the motor nameplate current should be treated as one of the most important pieces of information.

---

6. 690 VAC Three-Phase System

The drive is designed for a 690 VAC three-phase industrial power system.

690 VAC is commonly used for large industrial motors because higher operating voltage allows large motor power to be delivered without requiring the extremely high currents that would occur at lower voltage levels.

This makes the 20G14NF098JA0NNNNN particularly appropriate for large industrial installations where motors in the tens or hundreds of kilowatts are involved.

Typical equipment that may use this voltage class includes:

• Large pumps.
• Industrial fans.
• Large blowers.
• Compressors.
• Conveyors.
• Material-handling systems.
• Process machinery.
• Water-treatment equipment.
• Mining machinery.
• Cement and aggregate equipment.
• Large production machinery.

---

7. DC Input with Precharge

One of the more distinctive characteristics of this model is the DC Input with Precharge configuration.

The drive is not simply a conventional AC-input drive. It is intended to work within a power architecture that provides the appropriate DC bus arrangement.

The precharge function is important because the drive’s DC bus contains energy-storage capacitors. During initial energization, these capacitors need to be charged in a controlled manner.

A properly designed precharge circuit helps control the initial charging current and prevents an uncontrolled capacitor-charging event.

This type of configuration can be particularly useful in larger systems using common DC bus architectures or other coordinated drive-power arrangements.

---

8. Air-Cooled Construction

The 20G14NF098JA0NNNNN uses an air-cooled design.

For a high-power drive, cooling is an important part of the installation rather than simply a feature of the drive itself.

The cabinet must provide an appropriate airflow path and sufficient thermal capacity.

Important installation considerations include:

• Cabinet ambient temperature.
• Airflow direction.
• Cooling fan operation.
• Ventilation openings.
• Dust accumulation.
• Filter condition.
• Clearance around the drive.
• Heat generated by other cabinet equipment.
• Separation from external heat sources.
• Service access.

A drive installed in a poorly ventilated cabinet can experience excessive thermal stress even when the drive itself is correctly sized electrically.

---

9. Frame 6 Dimensions and Weight

The model is a Frame 6 configuration.

Approximate physical dimensions are shown below.

Physical Parameter	Approximate Specification
Model / Catalog Number	20G14NF098JA0NNNNN
Frame	Frame 6
Height	665.5 mm
Width	308 mm
Depth	346.4 mm
Approx. Weight	38.6 kg
Cooling	Air Cooled
Enclosure	Open Type

The approximate dimensions correspond to the drive hardware itself and should not be interpreted as the complete cabinet installation envelope.

A finished cabinet normally needs additional space for cable entry, wiring, grounding, ventilation, maintenance access, component clearance, and safe working space.

For an OEM cabinet, it is good practice to leave practical service space around the drive rather than designing the cabinet around the drive’s outer dimensions alone.

---

10. Open-Type Enclosure

The 20G14NF098JA0NNNNN is an Open Type drive.

This means that the drive is normally incorporated into a suitable electrical enclosure, cabinet, panel, or industrial control system.

The final enclosure should provide the environmental protection required by the application.

The cabinet designer should consider:

• Dust.
• Moisture.
• Temperature.
• Conductive contamination.
• Airflow.
• Electrical clearance.
• Grounding.
• Cable routing.
• EMC requirements.
• Maintenance access.

For industrial environments, the enclosure is an important part of the overall drive system.

---

11. Filtering and CM Jumper

The model is configured as Filtered, CM Jumper Installed.

Filtering can be useful for managing electrical noise generated by switching power electronics.

Variable-frequency drives naturally produce high-frequency components as the power transistors switch the motor waveform. Appropriate filtering, grounding, cable selection, shielding, and cabinet design can help maintain electromagnetic compatibility.

The CM jumper configuration should be considered together with the grounding system and overall electrical architecture.

It should not be changed without considering the actual power-system design.

---

12. Dynamic Braking

An important feature of the 20G14NF098JA0NNNNN is its DB Transistor configuration.

Dynamic braking is useful when the motor needs to decelerate and regenerative energy is returned from the motor into the drive DC bus.

When a large rotating load decelerates, the motor can act as a generator. The resulting energy raises the DC bus voltage.

A dynamic-braking system provides a controlled way to dissipate this energy through an appropriate braking resistor.

This can be especially valuable for:

• High-inertia machinery.
• Conveyors.
• Large rotating equipment.
• Rapid stopping applications.
• Machines requiring frequent deceleration.
• Certain material-handling applications.

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

---

13. Blank / No HIM

The drive is configured with Blank / No HIM.

HIM refers to the Human Interface Module used for local operation, parameter access, and monitoring.

A no-HIM configuration can be advantageous when the drive is integrated into a larger automation system.

For example, an operator may use a centralized HMI to control the entire machine rather than accessing the drive directly.

The HMI can display:

• Motor speed.
• Output frequency.
• Current.
• Drive status.
• Faults.
• Alarms.
• Operating commands.
• Process information.

This can produce a cleaner cabinet arrangement and a more consistent operator interface.

---

14. Communication and Automation Integration

The PowerFlex 755 platform is intended for integration into industrial control systems.

In a typical installation, the drive can operate as one component of a larger automation architecture.

The PLC may provide:

• Start command.
• Stop command.
• Speed reference.
• Direction command.
• Reset command.
• Operating mode.

The drive can return information such as:

• Running status.
• Actual speed.
• Output frequency.
• Output current.
• Fault status.
• Warning status.
• Diagnostic information.

This makes the PowerFlex 755 suitable for centralized machine control rather than isolated manual motor operation.

---

15. Product Applications

Large Industrial Pumps

The 20G14NF098JA0NNNNN can be used for large pump applications where variable speed is required.

Pump speed can be adjusted according to process demand, allowing the control system to regulate flow or pressure without always running the motor at full speed.

Typical applications include:

• Water circulation.
• Cooling-water systems.
• Process-water systems.
• Industrial fluid handling.
• Water treatment.
• Large utility pumps.

---

Large Fans and Blowers

Fans and blowers are another good application.

Variable-speed control can allow the motor to respond to actual airflow requirements.

This can be useful in:

• Industrial ventilation.
• Furnace systems.
• Exhaust systems.
• Cooling systems.
• Air-handling equipment.
• Process ventilation.

---

Conveyors

Large conveyors often require controlled acceleration and deceleration.

The PowerFlex 755 platform can provide controlled motor operation and can be integrated with a PLC-based conveyor control system.

Dynamic braking can also be useful in applications where the conveyor has substantial rotating or moving mass and needs controlled stopping.

---

Compressors

Industrial compressors can require substantial motor power.

The drive may be suitable where the compressor system is designed for variable-speed operation.

Compressor applications should receive particular attention during sizing because load characteristics can differ substantially from centrifugal fan or pump loads.

---

Mixers and Agitators

Large mixers and agitators may require controlled acceleration and variable operating speed.

The drive can be integrated into a process-control system where motor speed is adjusted according to production requirements.

---

Material Handling

Material-handling equipment can benefit from controlled acceleration, controlled stopping, speed adjustment, and integration with production-line controls.

Applications may include:

• Conveyors.
• Transfer equipment.
• Processing lines.
• Bulk-material systems.
• Production equipment.

---

Process Machinery

The drive can also be applied to larger process machines where the motor needs to be controlled as part of an automated production process.

Examples include:

• Industrial processing equipment.
• Manufacturing machinery.
• Large rotating machines.
• Utility systems.
• Production-line equipment.

---

16. Main Product Advantages

16.1 High-Power 690 VAC Operation

The 690 VAC voltage class makes the drive appropriate for large industrial motors.

This is one of the primary reasons to choose this model instead of a smaller low-voltage drive.

---

16.2 98 A Normal Duty Rating

The 98 A Normal Duty rating provides substantial motor-control capacity.

At approximately 90 kW Normal Duty, the model fits a significant range of industrial machinery.

---

16.3 75 kW Heavy Duty Rating

The 75 kW Heavy Duty rating provides additional flexibility for applications that require a more demanding overload profile.

---

16.4 DC Bus Integration

The DC input with precharge configuration makes the drive suitable for certain common-bus and DC-bus power architectures.

This can be especially useful in larger systems where several drives are part of a coordinated electrical system.

---

16.5 Dynamic Braking Capability

The integrated DB transistor configuration gives the system designer a useful option for handling regenerative energy during deceleration.

This is an important advantage for applications involving significant inertia or frequent stopping.

---

16.6 Air-Cooled Architecture

Air cooling is a familiar and practical thermal-management approach for industrial electrical cabinets.

It can be easier to maintain and integrate than a liquid-cooled arrangement in many applications.

---

16.7 PowerFlex 755 Platform

The PowerFlex 755 platform is designed for larger, more sophisticated industrial applications.

It provides a stronger platform for automation integration than many basic compact drives.

---

16.8 Open-Type Cabinet Integration

The open construction provides flexibility for OEM machine builders and system integrators.

The drive can be incorporated into a larger custom electrical system designed specifically around the application.

---

16.9 No-HIM Configuration

The no-HIM arrangement is useful where the machine already has a centralized HMI or control system.

This avoids requiring a permanent local operator keypad on the drive.

---

17. Recommended Same-Series Models

The following models are closely related PowerFlex 755 690 VAC configurations and provide a practical range of alternatives around the 90 kW class. The current and power ratings are the most important differences between them.

The 50 A model is a useful lower-power alternative, while the 119 A and 142 A models provide additional capacity above the 20G14NF098JA0NNNNN.

---

20. Five Popular Allen-Bradley Drive Models

For a broader Allen-Bradley comparison, the following models are useful because they represent commonly encountered PowerFlex drive configurations. They are not direct electrical replacements for the 20G14NF098JA0NNNNN, particularly because their voltage and power classes can differ.

Model	Series	Voltage Class	Current Class	Typical Application	Cooling	Approx. Dimensions	Approx. Weight
25B-D017N114	PowerFlex 525	480 VAC Class	17 A Class	Compact industrial machines	Air Cooled	Frame-dependent	Frame-dependent
25B-D024N114	PowerFlex 525	480 VAC Class	24 A Class	Pumps, fans, conveyors	Air Cooled	Frame-dependent	Frame-dependent
25B-D030N114	PowerFlex 525	480 VAC Class	30 A Class	General-purpose industrial machines	Air Cooled	Frame-dependent	Frame-dependent
20G11NC5P0JA0NNNNN	PowerFlex 755	480 VAC Class	50 A Class	Larger industrial machinery	Air Cooled	Frame-dependent	Frame-dependent
20G11NC072JA0NNNNN	PowerFlex 755	480 VAC Class	72 A Class	High-power industrial applications	Air Cooled	Frame-dependent	Frame-dependent

For these five models, the exact physical dimensions and weight should be treated as configuration-dependent because the frame, enclosure, and option combination can change the mechanical envelope.

---

21. PowerFlex 525 Compared With PowerFlex 755

The PowerFlex 525 and PowerFlex 755 families are intended for different levels of application complexity.

The PowerFlex 525 is generally more attractive when the priority is compact size, straightforward installation, lower power, and cost-effective control of smaller industrial motors.

The PowerFlex 755 is better suited to larger industrial machinery where the drive needs to become part of a more sophisticated automation and power-control system.

For a 690 VAC / 90 kW Normal Duty application, the 20G14NF098JA0NNNNN is much more directly aligned with the required voltage and power class.

A PowerFlex 525 model should therefore not be treated as a direct substitute simply because both products are variable-frequency drives.

---

22. Cabinet Design Considerations

Because the 20G14NF098JA0NNNNN is an open-type, air-cooled Frame 6 drive, cabinet design deserves careful attention.

The cabinet should provide adequate room for:

• Power wiring.
• DC bus wiring.
• Grounding conductors.
• Motor connections.
• Control wiring.
• Communication cables.
• Cooling airflow.
• Maintenance access.
• Component inspection.
• Cable bending radius.
• Heat dissipation.

The cabinet should also prevent hot exhaust air from being recirculated back into the drive’s cooling path.

---

23. Thermal Management

Thermal performance is one of the most important considerations for any high-power drive installation.

Heat can be generated by:

• The drive power stage.
• DC bus components.
• Cooling fans.
• Motor cables.
• Adjacent drives.
• Transformers.
• Contactors.
• Reactors.
• Other power electronics.

The total heat load should be considered when sizing the cabinet ventilation system.

A high-power drive should not be placed in a small sealed enclosure without a properly calculated thermal-management solution.

---

24. Motor Compatibility

Before choosing the drive, the motor should be checked carefully.

Motor Parameter	Selection Importance
Rated Voltage	Must be compatible with the system
Rated Current	Critical for drive sizing
Rated Power	Preliminary sizing reference
Rated Frequency	Required for proper motor control
Rated Speed	Important for speed-control requirements
Power Factor	Influences current requirements
Efficiency	Affects system loading
Service Factor	Relevant to overload evaluation
Motor Type	Determines suitable control strategy
Insulation	Important with PWM drive operation
Cable Length	Can affect EMC and motor-side electrical conditions
Load Type	Determines duty requirements

The most important rule is to check the motor nameplate current and required duty, rather than relying only on the motor’s kW value.

---

25. Dynamic Braking Application Considerations

Because this configuration includes a DB transistor, it can be considered for applications where controlled dissipation of regenerative energy is required.

Typical examples include:

• Large conveyors.
• High-inertia fans.
• Large rotating machinery.
• Rapid stopping systems.
• Material-handling equipment.
• Machines with frequent acceleration and deceleration.

However, the presence of a braking transistor does not mean that every braking resistor will be suitable.

The resistor must be selected based on:

• Motor power.
• Load inertia.
• Deceleration time.
• Stopping frequency.
• Regenerative energy.
• Duty cycle.
• Required braking torque.

---

26. Maintenance Recommendations

A high-power drive should be included in a regular preventive-maintenance program.

Important inspection points include:

• Cooling fans.
• Airflow paths.
• Ventilation openings.
• Dust accumulation.
• Cabinet temperature.
• Power terminals.
• Ground connections.
• DC bus connections.
• Motor connections.
• Control wiring.
• Communication cables.
• Fault history.
• Alarm history.
• Cabinet ventilation equipment.

In dusty industrial environments, cooling-system inspection may need to be performed more frequently.

---

27. Advantages for OEM Machine Builders

The 20G14NF098JA0NNNNN is particularly useful for OEMs building large industrial machinery.

The PowerFlex 755 platform provides a consistent approach to drive integration.

A machine builder can design different machine sizes around the same general drive family.

For example:

• Smaller machine → lower-current PowerFlex 755 model.
• Medium machine → 61 A or 82 A model.
• 90 kW machine → 98 A model.
• Larger machine → 119 A or 142 A model.

This can simplify engineering and maintenance across a product family.

---

28. Advantages for System Integrators

System integrators can also benefit from keeping a consistent PowerFlex platform throughout a project.

Potential benefits include:

• Familiar programming environment.
• Consistent parameter structure.
• Common troubleshooting methods.
• Easier technician training.
• Simplified spare-parts management.
• Consistent cabinet design concepts.
• Easier machine standardization.

For plants with multiple large motors, standardizing the drive family can be particularly valuable.

32. Overall Product Evaluation

The 20G14NF098JA0NNNNN is a high-power industrial AC drive designed for applications where a 690 VAC motor system, substantial current capacity, advanced drive functionality, and integration into a larger automation system are required.

Its 98 A Normal Duty / 90 kW rating places it well above the compact-drive category and makes it suitable for large industrial equipment.

The 82 A Heavy Duty / 75 kW rating gives the same drive additional flexibility for applications with more demanding load characteristics.

The DC input with precharge configuration makes this model particularly relevant to systems using DC-bus or common-bus power architectures.

The DB transistor is another useful feature, especially for machines where regenerative energy during deceleration needs to be controlled.

The air-cooled Frame 6 construction offers a practical solution for cabinet integration, while the open-type enclosure gives OEMs and system integrators flexibility when designing the complete electrical assembly.

The Blank / No HIM configuration is well suited to centralized automation, where the PLC and HMI provide the operator interface.

From an application standpoint, this model is particularly well matched to large pumps, fans, blowers, conveyors, compressors, process machinery, material-handling equipment, and other high-power rotating machinery.

The most important selection point is to verify the actual motor nameplate current and load duty before purchase. A 90 kW motor does not automatically mean that every 90 kW drive is appropriate, and the Normal Duty versus Heavy Duty rating can make a major difference.

For applications below this power level, the 20G14NF061JA0NNNNN and 20G14NF082JA0NNNNN are useful lower-rated alternatives.

For applications requiring more capacity, the 20G14NF119JA0NNNNN and 20G14NF142JA0NNNNN provide higher current and power ratings within the same general 690 VAC PowerFlex 755 family.

Overall, the 20G14NF098JA0NNNNN is a strong choice for a high-power industrial motor-control system where 690 VAC operation, 90 kW Normal Duty capacity, DC-bus integration, dynamic braking capability, air cooling, and PowerFlex 755 architecture are required.
