Allen-Bradley 20G11JF590JN0NNNNN PowerFlex 755 AC Drive — Detailed Product Information, Technical Parameters, Applications and Model Recommendations

1. Product Overview

The Allen-Bradley 20G11JF590JN0NNNNN is a high-power air-cooled AC variable frequency drive belonging to the PowerFlex 755 family. It is designed for demanding industrial motor-control applications where high output power, stable speed regulation, flexible control functions, industrial communication, and reliable continuous operation are required.

This model is configured for a 690 VAC three-phase power system and uses a high-current Frame 9 architecture. Its rated output current is 590 A, with power ratings that vary according to the selected load-duty category. The model is particularly suitable for large motors used in pumps, fans, conveyors, compressors, process equipment, material-handling systems, and other heavy industrial machinery.

The unit uses forced-air cooling and has an IP54 enclosure rating. Its 800 mm deep MCC-style construction makes it more appropriate for large industrial electrical rooms, motor-control centers, process plants, and centralized drive cabinets than for compact machine installations.

The model is configured with an embedded Ethernet/IP communication interface, standard protection, an AC input with DC terminals, an integrated EMC filtering arrangement, and a CM jumper installed. It does not include a HIM keypad in the standard configuration.

The combination of high voltage, high current, large motor capacity, industrial communication, and robust enclosure protection makes this model a high-power industrial drive rather than a small machine-level inverter.

---

3. Detailed Model Interpretation

The model number 20G11JF590JN0NNNNN contains a substantial amount of configuration information.

The most important part for identifying the product is the 20G11J family designation, which places the unit within the PowerFlex 755 AC drive platform.

The F590 portion identifies the high-current 690 V class configuration with a nominal current rating of approximately 590 A.

The J configuration indicates the current-generation configuration associated with the specified packaged-drive arrangement, while the remaining characters define options such as enclosure, keypad/HIM configuration, filtering, and other factory-selected characteristics.

In practical terms, the complete model number should be treated as one specific factory configuration rather than simply referring to it as a generic PowerFlex 755.

This distinction is important when replacing an existing drive. Two PowerFlex 755 units may have similar electrical ratings while having different enclosure depths, HIM configurations, filtering arrangements, braking options, communication options, or environmental characteristics.

---

4. Main Electrical Parameters

Parameter	Value
Model	20G11JF590JN0NNNNN
Input voltage	690 VAC
Input phases	3 phase
Nominal output current	590 A
Maximum low-duty power class	630 kW
Normal-duty power class	560 kW
Heavy-duty power class	450 kW
DC terminals	Yes
Dynamic braking transistor	No
EMC filtering	Yes
CM jumper	Installed
Frequency converter class	AC drive, below 1 kV

The 590 A output rating is the key characteristic of this model. It places the drive in the high-power industrial category and allows it to control substantially larger motors than the lower-current PowerFlex 755 variants.

The actual motor horsepower or kilowatt selection should always be based on the motor nameplate, motor service factor, load profile, acceleration requirements, ambient conditions, overload requirements, and the selected duty category rather than simply matching the motor’s nominal kW value.

---

5. Dimensions and Weight

For large industrial drives, dimensions are particularly important because installation space, ventilation, cable routing, maintenance clearance, cabinet depth, and lifting requirements can all affect the project design.

Physical Parameter	Reference Value
Model	20G11JF590JN0NNNNN
Installation depth class	800 mm
Reference height	Approx. 600 mm*
Reference width	Approx. 300 mm*
Reference depth	Approx. 400 mm*
Reference weight	Approx. 50 kg*
Enclosure	Type 12
Protection	IP54
Cooling method	Forced air
Installation environment	Industrial electrical room / MCC / control cabinet
Ventilation	Required
Mounting orientation	According to installation requirements
Maintenance clearance	Required around air inlet/outlet and service areas

*These dimensional and weight values are reference figures and should not be used as the sole basis for cabinet fabrication or structural calculations. A packaged Frame 9 drive can have a substantially different actual mechanical envelope depending on the specific enclosure and packaging arrangement.

For installation engineering, it is especially important to distinguish between the dimensions of the drive module itself and the dimensions of the complete packaged-drive assembly.

---

6. Cooling System

The 20G11JF590JN0NNNNN uses forced-air cooling.

Because the drive operates at a high current rating, heat dissipation is an important part of the overall installation design. The cooling fan is a backward-curved centrifugal type, designed to provide the airflow required by the power electronics.

The fan-related characteristics can be summarized as follows:

Cooling Parameter	Specification
Model	20G11JF590JN0NNNNN
Cooling method	Forced air
Fan type	Backward-curved centrifugal
Approximate airflow	1,805 m³/h
Approximate airflow	0.50 m³/s
Fan input power	Approximately 0.45 kW
Fan pressure differential	Approximately 527 Pa
Fan efficiency	Approximately 63.7%
Fan integration	Integrated into drive cooling system

Adequate cabinet ventilation is essential. If the surrounding temperature is high or the drive is installed in a confined electrical room, additional heat-management measures may be required.

---

7. Product Introduction

The PowerFlex 755 is a high-performance industrial AC drive platform designed for variable-speed control of large and technically demanding motors.

The 20G11JF590JN0NNNNN represents a high-current version of the platform intended for 690 V industrial power systems.

The drive converts incoming three-phase AC power into controlled electrical power for the motor. By regulating output voltage, frequency, and motor-control parameters, the drive can control motor speed and torque according to the requirements of the application.

Compared with fixed-speed motor operation, variable-speed control can provide significantly better process control. For centrifugal pumps and fans, reducing motor speed can also reduce energy consumption substantially when the application follows the relevant affinity-law behavior.

The PowerFlex 755 platform is also designed for integration into industrial automation architectures. The embedded Ethernet/IP capability allows the drive to exchange control and diagnostic information with an industrial controller without necessarily requiring a separate external communication adapter.

---

8. Product Applications

8.1 Pumps

The 20G11JF590JN0NNNNN is suitable for large industrial pumping systems.

Typical applications include:

• Water treatment systems
• Industrial water circulation
• Cooling-water systems
• Process-water pumps
• Chemical process pumps
• Mining slurry-related pumping systems
• Large-scale irrigation systems
• Industrial utility systems

For pump applications, variable-speed operation allows the motor speed to be adjusted according to actual process demand instead of running continuously at full speed.

This can improve pressure control, flow control, system stability, and energy efficiency.

---

8.2 Fans and Blowers

Large industrial fans and blowers are another important application.

Typical examples include:

• Industrial ventilation
• Furnace fans
• Boiler-related fans
• Exhaust systems
• Dust-collection systems
• Mining ventilation
• Process-air systems
• Large HVAC installations

The drive can regulate fan speed according to airflow requirements, allowing the process to operate closer to the required operating point.

---

8.3 Conveyors

The high-current capacity makes this type of drive suitable for large conveyor systems.

Potential applications include:

• Mining conveyors
• Bulk-material conveyors
• Cement plants
• Steel plants
• Ports and terminals
• Aggregate handling
• Warehouse and process-material handling

A variable-frequency drive provides controlled acceleration and deceleration, which can reduce mechanical shock to belts, gearboxes, couplings, and other transmission components.

---

8.4 Compressors

Large industrial compressors may also require variable-speed control.

Applications can include:

• Industrial air systems
• Process gas systems
• Manufacturing plants
• Chemical facilities
• Utility systems
• Large refrigeration-related systems

The actual suitability depends on compressor type, motor requirements, speed range, torque profile, and process-control requirements.

---

8.5 Process Machinery

The drive can also be considered for high-power process machinery where controlled motor speed is required.

Examples include:

• Mixers
• Agitators
• Large material-processing equipment
• Industrial mills
• Processing lines
• Large machine systems
• Heavy-duty production equipment

The ability to integrate drive control with a larger automation system is particularly valuable in continuous-process applications.

---

9. Main Product Advantages

9.1 High-Power Capability

The biggest advantage of this model is its high current and power capability.

With a nominal output current of 590 A and a low-duty rating reaching approximately 630 kW, the drive is designed for applications involving very large motors.

This allows one drive platform to handle applications that would be outside the practical range of smaller variable-frequency drives.

---

9.2 690 VAC Industrial Compatibility

The 690 VAC class is widely used in heavy industrial installations.

A 690 V drive can provide advantages in large-motor applications because the same power level can be delivered at lower current compared with a lower-voltage system.

This can help with:

• Large-motor power distribution
• Cable sizing
• Electrical system architecture
• Large industrial motor installations
• Centralized drive systems

---

9.3 Embedded Ethernet/IP

The built-in Ethernet/IP capability is a major advantage in modern industrial automation.

It enables the drive to exchange information with controllers and supervisory systems.

Typical information can include:

• Start/stop commands
• Speed references
• Actual speed
• Output current
• Motor status
• Fault information
• Warning information
• Diagnostic information
• Operating parameters

This can reduce the need for separate communication hardware and simplify integration into an Ethernet-based automation network.

---

9.4 IP54 / Type 12 Protection

The IP54 / Type 12 configuration provides considerably more environmental protection than an open-frame drive.

It is appropriate for industrial environments where protection from dust and water ingress is required within the applicable enclosure limits.

However, IP54 should not be interpreted as waterproofing or as permission to install the drive in an unrestricted outdoor environment.

---

9.5 Strong Process-Control Capability

PID functionality makes the drive particularly useful for process applications.

For example, a pump can be controlled according to pressure rather than simply according to a fixed speed command.

This can allow the drive to automatically increase or decrease motor speed according to the process feedback signal.

---

9.6 Flexible Industrial Architecture

The PowerFlex 755 platform is designed around a modular and configurable industrial-drive concept.

This allows the same basic drive family to be used across different applications while selecting appropriate configurations and accessories.

This is beneficial for companies that want to standardize drive technology across multiple production lines.

---

9.7 High-Current Frame 9 Platform

Frame 9 provides the physical and electrical capacity needed for high-power industrial applications.

For large motors, using a correctly sized high-power drive can simplify the system architecture and provide additional operating margin when the application is properly engineered.

---

11. Five Same-Series / Closely Related Model Recommendations

The following models are closely related PowerFlex 755 configurations and are useful when selecting an alternative according to current rating, motor power, keypad configuration, or application requirements.

Recommended Model	Series	Input Voltage	Current	LD Power	ND Power	HD Power	Frame	Protection	Keypad Configuration
20G11JF650JN0NNNNN	PowerFlex 755	690 VAC	650 A	710 kW	630 kW	500 kW	9	IP54	No standard HIM
20G11JF710JN0NNNNN	PowerFlex 755	690 VAC	710 A	800 kW	710 kW	590 kW	9	IP54	No standard HIM
20G11JF765JN0NNNNN	PowerFlex 755	690 VAC	765 A	850 kW	750 kW	630 kW	9	IP54	No standard HIM
20G11JF795JN0NNNNN	PowerFlex 755	690 VAC	795 A	900 kW	800 kW	710 kW	9	IP54	No standard HIM
20G11JF590JN4NNNNN	PowerFlex 755	690 VAC	590 A	630 kW	560 kW	450 kW	9	IP54	Enhanced LCD / full numeric HIM

The first four alternatives mainly provide different current and power capacities.

The 20G11JF650JN0NNNNN is a logical step above the 590 A model when the application requires additional current capacity.

The 20G11JF710JN0NNNNN is suitable when the motor load is substantially larger and a higher power rating is required.

The 20G11JF765JN0NNNNN and 20G11JF795JN0NNNNN are intended for still larger applications and provide additional current capacity for high-power motors.

The 20G11JF590JN4NNNNN is particularly interesting when the same basic electrical rating is required but local operator access through an enhanced LCD/full numeric HIM is desired.

12. Physical Parameters of the Recommended Related Models

Because these models belong to the same large-frame PowerFlex 755 configuration family, their physical installation characteristics are broadly similar, but the exact enclosure and internal arrangement can vary.

Model	Frame	Installation Depth Class	Reference Dimension	Reference Weight
20G11JF650JN0NNNNN	9	800 mm MCC style	Approx. 600 × 300 × 400 mm*	Approx. 50 kg*

13. Five Popular Allen-Bradley Models from Related Drive Families

For applications where the user does not necessarily need the exact 690 V / 590 A specification, the following Allen-Bradley drive models are useful alternatives to consider.

Model	Product Family	Typical Voltage Class	Current / Power Class	Cooling	Main Application
20G11JF590JN0NNNNN	PowerFlex 755	690 VAC	590 A / up to approx. 630 kW LD	Forced air	Large industrial motors
20G11JF650JN0NNNNN	PowerFlex 755	690 VAC	650 A / up to approx. 710 kW LD	Forced air	Large pumps, fans, conveyors
20G11JF710JN0NNNNN	PowerFlex 755	690 VAC	710 A / up to approx. 800 kW LD	Forced air	Heavy industrial machinery
20G11JF765JN0NNNNN	PowerFlex 755	690 VAC	765 A / up to approx. 850 kW LD	Forced air	Very large motors and process equipment
20G11JF795JN0NNNNN	PowerFlex 755	690 VAC	795 A / up to approx. 900 kW LD	Forced air	Extremely high-power applications

These five models are particularly relevant if the project is based around the PowerFlex 755 high-power platform.

When selecting between them, the most important parameter is not simply the motor’s nameplate kW. The application duty must also be considered.

A conveyor, crusher, mixer, or other high-torque application may require a heavier-duty rating than a centrifugal fan or pump.

*Reference only; actual product weight depends on the configured package and installation arrangement.

---

15. How to Select Between These Models

If the motor’s rated power is around 450–500 kW and the application requires heavy-duty operation, the 590 A version can be a suitable starting point.

If the motor approaches the upper end of the 590 A model’s normal operating range, moving to the 650 A version can provide additional electrical capacity.

For applications above approximately 700 kW, the 710 A model becomes more attractive.

For motors around 750–850 kW, the 765 A model provides a larger current margin.

For extremely high-power applications approaching 900 kW low-duty operation, the 795 A model is the stronger choice among the models listed above.

The final choice should be based on motor current rather than motor kW alone.

For example, two motors with the same nominal power may have different rated currents because of differences in motor efficiency, power factor, voltage, motor design, and operating conditions.

---

16. Advantages Compared with a Smaller Industrial Drive

The 20G11JF590JN0NNNNN offers several advantages when compared with smaller drives.

First, it is designed for very large motor loads.

Second, the 690 VAC class allows it to be used in industrial power systems designed around medium/high-voltage motor distribution below 1 kV.

Third, the PowerFlex 755 architecture provides extensive control and communication functionality.

Fourth, the integrated Ethernet/IP interface can simplify communication with automation systems.

Fifth, the IP54 / Type 12 enclosure configuration provides a degree of environmental protection suitable for many industrial installations.

Sixth, the high-current Frame 9 platform can support applications where conventional smaller drives would require multiple units or would simply be electrically undersized.

---

17. Recommended Applications by Load Type

Load Type	Suitability	Reason
Large centrifugal pump	Excellent	Variable speed and PID control
Large fan	Excellent	Speed control and energy optimization
Large blower	Excellent	Process airflow control
Conveyor	Excellent	Controlled acceleration and speed
Mining conveyor	Excellent	High-current capability
Compressor	Very Good	High-power motor control
Mixer	Very Good	High-power torque control
Process pump	Excellent	Closed-loop process control
Crusher	Application-dependent	Heavy-duty torque requirements must be checked
Large mill	Application-dependent	Duty cycle and torque profile are critical
Small motor	Poor choice	Excessively large for the application
Residential HVAC	Not recommended	Industrial high-power architecture is unnecessary

---

18. Important Engineering Considerations

The 20G11JF590JN0NNNNN is a large industrial electrical device and should be selected as part of a complete motor-drive system rather than as an isolated component.

The motor’s rated current should be checked first.

The application’s acceleration time should then be evaluated.

The required overload capacity should also be considered.

The installation ambient temperature is another important factor. High ambient temperatures can reduce available drive capacity and increase cooling requirements.

The installation altitude should also be evaluated when applicable.

Cable length between the drive and motor can influence output filtering and motor insulation considerations.

Grounding, EMC, short-circuit protection, disconnecting means, cabinet ventilation, cable routing, and electrical clearances should all be considered during system design.

For high-power motors, harmonic performance and power-quality requirements may also be important.

---

19. Configuration Without Standard HIM

One notable characteristic of 20G11JF590JN0NNNNN is that the standard configuration does not include a HIM keypad.

This does not mean that the drive cannot be controlled or configured.

The drive can be integrated into an industrial control system through its communication interface, while commissioning and parameter adjustment can be performed using appropriate engineering tools and system interfaces.

This configuration can be particularly suitable for centralized automation systems where operators do not need a dedicated keypad mounted directly on every drive.

For applications where local operator interaction is important, a related configuration such as 20G11JF590JN4NNNNN can be considered because it provides an enhanced LCD/full numeric HIM configuration.

22. Overall Evaluation

The 20G11JF590JN0NNNNN is a high-capacity industrial variable-frequency drive designed for large 690 VAC motor systems.

Its main strengths are its 590 A output capability, high power rating, PowerFlex 755 architecture, integrated Ethernet/IP communication, IP54 / Type 12 protection, forced-air cooling, PID capability, and suitability for large industrial motor applications.

It is particularly attractive for applications where a large motor must be controlled continuously and integrated into a modern automation system.

For pumps and fans, the drive can provide accurate speed regulation and process control.

For conveyors and heavy machinery, it can provide controlled acceleration and deceleration while allowing the motor speed to be adjusted to process requirements.

For large process systems, the integrated industrial communication capability can simplify the connection between the drive and the supervisory control architecture.

The main point to keep in mind is that this is a very large drive. It should not be selected merely because its kW rating appears to match a motor. The motor current, duty classification, overload requirement, speed range, acceleration requirement, environmental conditions, cooling arrangement, and installation method should all be checked before final selection.

For applications requiring the same basic electrical class but additional operating margin, the 650 A, 710 A, 765 A, and 795 A PowerFlex 755 configurations are logical alternatives.

For applications requiring the same 590 A electrical rating but local operator access, the enhanced-HIM configuration 20G11JF590JN4NNNNN is a useful related option.

Overall, the 20G11JF590JN0NNNNN can be regarded as a high-power, industrial-grade PowerFlex 755 drive intended for large motors and demanding continuous-duty applications, particularly in sectors such as mining, water treatment, cement, steel, material handling, process manufacturing, utilities, and large-scale HVAC.

For a final engineering selection, the most important checks are the motor nameplate current, selected duty class, actual load torque curve, ambient temperature, installation altitude, enclosure arrangement, cooling airflow, cable system, braking requirements, and required communication/control architecture.
