1. Product Overview

The Allen-Bradley 20G1ANF061JN0NNNNN is a PowerFlex 755 series air-cooled variable frequency AC drive designed for high-power three-phase industrial motor applications.

This model is configured for a 690 VAC, three-phase power supply and provides a 61 A normal-duty rating with a 55 kW normal-duty power rating. Under heavy-duty conditions, it is rated at approximately 50 A and 45 kW.

The drive uses a Frame 6 mechanical configuration and forced-air cooling. Its open-type construction is intended for installation inside a suitable electrical cabinet or enclosure.

The model includes embedded EtherNet/IP communication, making it suitable for integration into automated industrial control systems where motor commands, operating status, faults and other drive information need to be exchanged over an industrial network.

The JN0 configuration is also important because this version does not include the internal dynamic-braking transistor configuration found on certain closely related JA0 versions.

This makes the 20G1ANF061JN0NNNNN particularly suitable for installations where the drive’s 690 VAC rating, 61 A normal-duty capacity, 55 kW power rating and network communication are required, while an internal dynamic-braking transistor is not part of the selected configuration.

The drive is intended for demanding industrial environments and can be used for equipment such as conveyors, pumps, fans, material-handling machinery, process equipment, manufacturing machinery and other large AC motor systems.

4. Product Introduction

The 20G1ANF061JN0NNNNN is a high-power industrial variable frequency drive designed to provide adjustable-speed control for three-phase AC motors.

Its 690 VAC input rating places it within the higher-voltage industrial drive category, making it suitable for motor systems where 690 VAC is the required supply voltage.

With a 61 A normal-duty output rating, the drive provides approximately 55 kW of normal-duty motor capacity.

For heavy-duty applications, the available rating is approximately 50 A and 45 kW.

This distinction between normal-duty and heavy-duty ratings is important when selecting the drive for an actual machine.

A motor operating a centrifugal fan, for example, can have a very different load profile from a motor driving a heavily loaded conveyor.

Likewise, a machine that starts and stops frequently can place greater demands on the drive than a machine that operates continuously at a relatively stable speed.

The drive should therefore be selected according to motor nameplate current, actual load characteristics, acceleration requirements, operating cycle and environmental conditions rather than simply matching the motor’s nominal kW value.

The PowerFlex 755 platform is designed for applications where the drive needs to perform more than basic speed conversion.

The drive can become part of a larger industrial control system, allowing motor operation to be coordinated with automation equipment.

The embedded EtherNet/IP communication function is particularly useful for networked machinery.

The drive can exchange operating information with a suitable control system, allowing functions such as start/stop control, speed references, status monitoring and fault information to be incorporated into the overall machine-control strategy.

The open-type construction means the drive is normally installed within an appropriate electrical cabinet or enclosure.

The final enclosure needs to provide the required environmental protection while maintaining suitable cooling airflow around the drive.

5. Understanding the Model Number

The complete catalog number is:

20G1ANF061JN0NNNNN

Using the complete catalog number is important because the PowerFlex 755 family contains many configurations with different voltage classes, current ratings, braking arrangements and other options.

The 20G1 portion identifies the PowerFlex 755 drive family.

The ANF061 portion identifies the 690 VAC family and 61 A configuration.

The JN0 portion is particularly important for this model because it identifies the configuration without the internal dynamic-braking transistor.

This means that the 20G1ANF061JN0NNNNN should not automatically be treated as identical to the similarly rated 20G1ANF061JA0NNNNN.

Both configurations have the same basic 690 VAC, 61 A normal-duty and 55 kW normal-duty ratings, but their braking configurations differ.

For replacement work, purchasing and engineering documentation, the complete catalog number should therefore be retained.

6. Electrical Rating

The drive is designed for 690 VAC three-phase operation.

Its normal-duty output rating is:

61 A / 55 kW

Its heavy-duty output rating is:

50 A / 45 kW

These ratings provide a useful selection range for large industrial motor applications.

The 690 VAC voltage class is especially relevant to industrial installations using higher-voltage motors.

When selecting the drive, the motor’s rated voltage must be compatible with the electrical system.

The motor’s full-load current should also be compared directly against the applicable drive current rating.

The motor power rating alone should not be used as the final selection criterion.

7. Normal-Duty Operation

The 55 kW normal-duty rating is appropriate for applications where the motor load profile remains within the normal-duty operating characteristics of the drive.

Typical applications can include pumps, fans, conveyors and other equipment with relatively predictable load requirements.

The actual motor current remains the key selection factor.

A 55 kW motor does not necessarily have the same current requirement in every motor design or operating condition, so the motor nameplate should always be checked.

8. Heavy-Duty Operation

The heavy-duty rating is approximately 45 kW at 50 A.

Heavy-duty operation is relevant to machines where the motor can experience greater torque demand or more demanding acceleration and overload conditions.

Examples may include heavily loaded conveyors, certain material-handling machines and equipment with substantial mechanical inertia.

When the application is heavy-duty, the 45 kW heavy-duty rating should be used rather than the 55 kW normal-duty rating.

9. Dynamic Braking Configuration

The 20G1ANF061JN0NNNNN does not include the internal dynamic-braking transistor.

This is one of the most important configuration differences between this model and the closely related JA0 version.

Dynamic braking can be important when a motor-driven machine needs to decelerate a high-inertia load.

However, not every application requires dynamic braking.

For applications where the machine has relatively gentle deceleration requirements and does not require an internal dynamic-braking transistor, the JN0 configuration can be appropriate.

If the machine requires rapid stopping or has significant regenerative energy during deceleration, the complete braking strategy should be evaluated separately.

The absence of an internal dynamic-braking transistor should therefore be considered during drive selection.

10. Embedded EtherNet/IP Communication

The drive includes embedded EtherNet/IP communication.

This makes it suitable for industrial automation architectures in which variable frequency drives are connected to a central controller or supervisory system.

Typical network functions can include:

Network Function	Typical Purpose
Start Command	Starting the motor through the control system
Stop Command	Stopping the motor
Speed Reference	Sending a desired operating speed
Status Monitoring	Checking whether the drive is running or stopped
Fault Monitoring	Receiving drive fault information
Alarm Monitoring	Monitoring abnormal operating conditions
Parameter Access	Accessing selected drive parameters
Diagnostic Data	Supporting troubleshooting
Multi-Drive Control	Coordinating multiple drives
Production Control	Adjusting motor operation according to production requirements

11. Product Applications

11.1 Conveyor Systems

The 20G1ANF061JN0NNNNN is suitable for large conveyor systems where variable-speed motor control is required.

The drive can provide gradual acceleration and deceleration, helping to reduce sudden mechanical loading.

Variable-speed control can also allow conveyor speed to be adjusted according to production requirements.

For conveyors that do not require an internal dynamic-braking transistor, this configuration can provide the necessary variable-speed control while retaining the industrial communication capabilities of the PowerFlex 755 platform.

11.2 Material Handling

Material-handling systems often require controlled motor speed.

Large transfer conveyors, rollers and other motor-driven equipment can use a variable frequency drive to regulate movement.

Network communication can also allow the drive to participate in a larger automated material-handling system.

11.3 Industrial Pumps

Large pumps are another common application for variable frequency drives.

A pump does not always need to operate at full speed.

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

This can provide greater operating flexibility compared with a simple fixed-speed motor arrangement.

11.4 Large Industrial Fans

Large ventilation and process fans can also benefit from variable-speed operation.

The drive can adjust the motor speed according to the required airflow.

This can be useful in industrial ventilation systems and process-air applications.

11.5 Process Machinery

The drive can be applied to industrial process equipment where motor speed needs to be controlled as part of the overall process.

Examples include rotating equipment, processing machinery, production systems and other electrically driven equipment.

11.6 Manufacturing Equipment

Large automated manufacturing machines may require adjustable motor speed and network-based control.

The drive can receive speed commands from the machine-control system and provide operating status back to the automation network.

This allows motor operation to be incorporated into a coordinated production process.

11.7 General Industrial Motor Control

The drive can also be considered for other large three-phase AC motor applications where the voltage, current, duty cycle, environmental conditions and control requirements fall within the applicable range.

12. Main Product Advantages

12.1 690 VAC High-Voltage Capability

The 690 VAC rating makes this drive suitable for higher-voltage industrial motor systems.

This expands its application range beyond smaller low-voltage machine drives.

12.2 55 kW Normal-Duty Capacity

The 55 kW normal-duty rating allows the drive to control relatively large industrial motors.

It is therefore appropriate for equipment requiring considerably more capacity than compact machine-level drives.

12.3 45 kW Heavy-Duty Capacity

The 45 kW heavy-duty rating provides a separate operating range for applications with more demanding load conditions.

This gives system designers a clearer way to match the drive to the actual machine duty.

12.4 Embedded EtherNet/IP

The integrated communication capability makes the drive easier to incorporate into networked automation systems.

It can reduce the need for additional external communication hardware for standard network integration.

12.5 Industrial Motor Control

The PowerFlex 755 platform is designed for industrial variable-speed motor applications.

The drive can provide adjustable speed, controlled acceleration and controlled deceleration for appropriately selected motor systems.

12.6 Forced-Air Cooling

Forced-air cooling is used to manage the heat produced by the power electronics.

For a high-power drive, appropriate cabinet ventilation and airflow are important parts of the installation design.

12.7 Flexible Installation

The open-type construction allows the drive to be installed as part of a larger electrical cabinet.

This gives panel designers flexibility when arranging circuit protection, disconnects, control equipment, communication equipment and other components around the drive.

12.8 Standardized Frame

The Frame 6 configuration provides a defined mechanical platform for this power class.

This can simplify cabinet layout when several drives from the same family are used in one industrial installation.

13. Dimensions and Weight

The physical size of the drive is an important consideration for cabinet design.

Mechanical Parameter	Specification
Model	20G1ANF061JN0NNNNN
Frame	Frame 6
Height	665.5 mm
Width	308 mm
Depth	346.4 mm
Overall Dimensions	665.5 × 308 × 346.4 mm
Approx. Weight	38.6 kg
Cooling	Forced Air
Construction	Open Type
Installation	Electrical Cabinet / Enclosure

The approximately 38.6 kg equipment weight should be considered when designing the cabinet mounting structure.

The mounting surface should be sufficiently strong to support the drive during normal operation.

Additional space should be provided around the equipment for power cables, control wiring, communication wiring and cooling airflow.

The physical dimensions should also be considered together with cable bending radius and maintenance access rather than treating the drive dimensions as the complete cabinet space requirement.

14. Cooling and Cabinet Design

The drive uses forced-air cooling.

A suitable cabinet should therefore allow the cooling air to move through the drive without excessive obstruction.

The cabinet designer should also consider the heat generated by other electrical components installed in the same enclosure.

If several drives or other high-power devices are installed together, the total cabinet heat load should be evaluated.

Dust accumulation should also be controlled because excessive contamination can affect cooling performance and electrical reliability.

The final cabinet design should take into account ambient temperature, airflow, heat dissipation, installation clearances and maintenance access.

15. Installation Environment

The drive uses an open-type configuration rather than functioning as a fully sealed standalone field enclosure.

The final installation therefore requires a suitable cabinet or enclosure.

The enclosure should provide protection appropriate to the actual installation environment.

Important considerations include:

Environmental Factor	Design Consideration
Dust	Prevent excessive contamination
Moisture	Provide appropriate enclosure protection
Temperature	Maintain suitable operating conditions
Airflow	Maintain adequate cooling
Heat	Account for total cabinet heat load
Vibration	Provide secure mechanical mounting
Cable Routing	Separate and organize power/control wiring appropriately
Maintenance	Provide sufficient service access
Electrical Clearance	Maintain appropriate installation clearances

16. Typical Industrial Applications

Application	Typical Drive Requirement
Large Conveyor	Variable speed and controlled acceleration
Material Handling	Adjustable motor speed
Industrial Pump	Process-dependent speed control
Large Fan	Variable airflow control
Manufacturing Machinery	Networked motor control
Process Equipment	Adjustable operating speed
Rotating Machinery	Controlled acceleration/deceleration
Automated Production	EtherNet/IP integration
Industrial Auxiliary Equipment	Large three-phase motor control
General Heavy Machinery	High-voltage variable-speed operation

17. Five Same-Series / Closely Related Models

The following models belong to the same 690 VAC PowerFlex 755 family and provide useful alternatives for different motor sizes.

Model	Voltage	Normal-Duty Current	Normal-Duty Power	Heavy-Duty Current	Heavy-Duty Power	Frame	Approx. Dimensions	Approx. Weight
20G1ANF034JN0NNNNN	690 VAC	34 A	30 kW	30 A	22 kW	Frame 6	Frame 6 configuration	Frame-dependent

20G1ANF050JN0NNNNN	690 VAC	50 A	45 kW	46 A	37 kW	Frame 6	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6 kg
20G1ANF061JN0NNNNN	690 VAC	61 A	55 kW	50 A	45 kW	Frame 6	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6 kg
20G1ANF082JN0NNNNN	690 VAC	82 A	75 kW	61 A	55 kW	Frame 6	Frame 6 configuration	Frame-dependent

The 690 VAC family provides a progression of current and power ratings, allowing the drive size to be matched to different motor applications.

The 20G1ANF034JN0NNNNN is appropriate for a lower power requirement within this group.

The 20G1ANF046JN0NNNNN provides a 37 kW normal-duty rating.

The 20G1ANF050JN0NNNNN provides 45 kW normal-duty capacity.

The target 20G1ANF061JN0NNNNN increases the normal-duty rating to 55 kW.

The 20G1ANF082JN0NNNNN provides a substantially higher 75 kW normal-duty capacity.

The current and power progression within this family is useful when a facility has several motors with different sizes but wants to maintain a common drive platform.

18. Same-Series Electrical Comparison

Model	Normal-Duty Rating	Heavy-Duty Rating	Voltage	Frame
20G1ANF034JN0NNNNN	34 A / 30 kW	30 A / 22 kW	690 VAC	6
20G1ANF046JN0NNNNN	46 A / 37 kW	34 A / 30 kW	690 VAC	6
20G1ANF050JN0NNNNN	50 A / 45 kW	46 A / 37 kW	690 VAC	6
20G1ANF061JN0NNNNN	61 A / 55 kW	50 A / 45 kW	690 VAC	6
20G1ANF082JN0NNNNN	82 A / 75 kW	61 A / 55 kW	690 VAC	6

The target model sits between the 50 A and 82 A versions in this sequence.

This makes it useful for applications where a 45 kW normal-duty drive is insufficient but a 75 kW drive would provide more capacity than required.

The final selection should still be based on actual motor current and application duty rather than selecting the nearest nominal power rating.

19. Five Same-Brand Related / Common Models

The following models represent other commonly encountered Allen-Bradley variable-frequency-drive configurations.

Model	Series	Voltage Class	Main Rating	Typical Application	Approx. Dimensions	Approx. Weight

25B-D017N104	PowerFlex 525	480 VAC class	17 A class	Compact industrial machinery	Configuration dependent	Configuration dependent
20F11NC2P2JA0NNNNN	PowerFlex 753	480 VAC class	2.2 A class	Industrial motor control	Configuration dependent	Configuration dependent
20G1ANF050JN0NNNNN	PowerFlex 755	690 VAC	50 A ND / 46 A HD	Large industrial motors	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6 kg
20G1ANF082JN0NNNNN	PowerFlex 755	690 VAC	82 A ND / 61 A HD	Higher-power industrial motors	Frame-dependent	Frame-dependent

The PowerFlex 525 models represent a more compact class of variable frequency drives.

The PowerFlex 753 model belongs to a larger industrial drive family and is suitable for applications requiring industrial motor control and automation integration.

The 20G1ANF050JN0NNNNN is closely related to the target model and provides a lower current and power rating.

The 20G1ANF082JN0NNNNN is a higher-capacity 690 VAC PowerFlex 755 configuration.

These models can therefore be useful when comparing drive families across different motor sizes and machine requirements.

20. Comparison with the JA0 Configuration

The most relevant comparison for the target model is the similarly rated 20G1ANF061JA0NNNNN.

Parameter	20G1ANF061JN0NNNNN	20G1ANF061JA0NNNNN
Series	PowerFlex 755	PowerFlex 755
Voltage	690 VAC	690 VAC
Phase	3 Phase	3 Phase
Normal-Duty Current	61 A	61 A
Normal-Duty Power	55 kW	55 kW
Heavy-Duty Current	50 A	50 A
Heavy-Duty Power	45 kW	45 kW

Approx. Dimensions	665.5 × 308 × 346.4 mm	665.5 × 308 × 346.4 mm
Approx. Weight	38.6 kg	Configuration dependent

The primary difference is the braking configuration.

The JN0 version is configured without the internal dynamic-braking transistor.

The JA0 version includes the dynamic-braking transistor.

This distinction should be checked carefully when replacing an existing drive because braking requirements can be an important part of the machine’s operating sequence.

21. Advantages in Automated Production Systems

The drive is particularly useful when the motor is not intended to operate simply as an on/off device.

A variable frequency drive can provide a controlled relationship between motor speed and machine operation.

For automated production equipment, this can allow the motor speed to change according to production rate.

The embedded EtherNet/IP communication can also allow the drive to communicate with the larger automation system.

This can make it possible to coordinate drive operation with other equipment on the production line.

For example, a conveyor motor can be controlled according to upstream and downstream machine conditions.

A pump motor can be adjusted according to process requirements.

A fan motor can be controlled according to ventilation demand.

A rotating machine can operate at different speeds during different production stages.

22. Maintenance Considerations

The cooling system should be included in regular maintenance activities.

The forced-air cooling path should be kept reasonably clean and unobstructed.

Dust accumulation can reduce airflow and contribute to increased operating temperature.

The electrical connections should also be checked according to the applicable maintenance procedure.

The drive’s communication and diagnostic information can be useful when troubleshooting a machine.

A maintenance team can use drive status, alarms and fault information to help identify abnormal operating conditions.

23. Cabinet Design Considerations

When installing the 20G1ANF061JN0NNNNN, the cabinet should be designed around both the physical dimensions and thermal requirements.

The approximately 665.5 mm height, 308 mm width and 346.4 mm depth provide the basic mechanical envelope.

The cabinet should not be designed with only those dimensions and no additional space.

Power cables require space for routing and bending.

Control cables and communication cables also need appropriate routing.

Maintenance personnel need sufficient access to service the equipment.

The cabinet also needs enough airflow to support forced-air cooling.

For these reasons, the final cabinet footprint will normally be larger than the bare dimensions of the drive itself.

27. Product Series

Series: PowerFlex 755

The PowerFlex 755 series is designed for industrial variable-speed AC motor applications.

The series covers a broad range of motor ratings and voltage classes, allowing equipment designers to select different drive capacities while retaining a common product platform.

The 20G1ANF061JN0NNNNN belongs specifically to the 690 VAC three-phase portion of the PowerFlex 755 family.

The 690 VAC models include a range of current ratings, allowing the same general drive platform to be used across different motor sizes.

This can be useful for plants where standardization is important.

Using related drive configurations can simplify training, maintenance practices, commissioning procedures and spare-parts planning.

28. Brand

Brand: Allen-Bradley

The model 20G1ANF061JN0NNNNN is an Allen-Bradley PowerFlex 755 AC drive.

For purchasing and technical documentation, the complete model number should be retained.

The series name alone does not identify all of the electrical and configuration characteristics.

The difference between the JN0 and JA0 configurations is a good example of why the complete catalog number matters.

29. Why the 20G1ANF061JN0NNNNN Is Used

The model is designed for situations where a conventional fixed-speed motor starter is not sufficient.

A variable-speed application may require the motor to operate at different speeds depending on the production process.

The drive provides the electronic interface between the industrial power system and the motor.

It controls the frequency and voltage supplied to the motor so that motor speed can be adjusted according to the application.

In an automated system, the drive can also receive commands through its industrial communication interface.

This makes it possible to combine motor control with machine sequencing and process control.

30. Final Product Summary

The Allen-Bradley 20G1ANF061JN0NNNNN is a PowerFlex 755, 690 VAC, three-phase, 61 A normal-duty, 55 kW normal-duty AC drive designed for industrial variable-speed motor control.

Its heavy-duty rating is approximately 50 A and 45 kW, providing a separate operating range for applications with more demanding load characteristics.

The drive uses Frame 6 forced-air cooling and an open-type installation arrangement.

Its approximate physical dimensions are 665.5 mm × 308 mm × 346.4 mm, and its approximate weight is 38.6 kg.

The embedded EtherNet/IP communication capability makes it suitable for integration into industrial automation networks.

The most important configuration characteristic of this particular model is the JN0 configuration without an internal dynamic-braking transistor.

This makes it different from the similarly rated JA0 configuration.

The drive can be used in a wide variety of industrial applications, including conveyors, pumps, fans, material-handling systems, process machinery, manufacturing equipment and other large three-phase AC motor applications.

When selecting this drive, the most important factors are the 690 VAC supply voltage, 61 A normal-duty current, 50 A heavy-duty current, motor nameplate current, motor power, duty cycle, acceleration and deceleration requirements, braking requirements, cabinet design, cooling requirements and communication architecture.

The complete catalog number 20G1ANF061JN0NNNNN should be used when purchasing or replacing the equipment.

For a 690 VAC industrial motor application around the 55 kW normal-duty / 45 kW heavy-duty range, this model provides a substantial combination of variable-speed motor control, industrial network integration and Frame 6 construction.

Its configuration is particularly appropriate when the application requires the capabilities of the PowerFlex 755 platform but does not require the internal dynamic-braking transistor associated with the JA0 version.
