Allen-Bradley 20G1AJD710AN0NNNNN PowerFlex 755 AC Drive

1. Product Overview

The Allen-Bradley 20G1AJD710AN0NNNNN is a high-power PowerFlex 755 AC Drive designed for large three-phase industrial motors and demanding variable-speed applications.

This model belongs to the PowerFlex 755 AC Packaged Drive family and is configured for the 480 VAC three-phase industrial power class.

With a rated output current of approximately 710 A, the drive is positioned toward the high-power end of the air-cooled PowerFlex 755 range.

Its published power capability is approximately 650 HP for Light Duty, 600 HP for Normal Duty, and 450 HP for Heavy Duty.

This makes the drive suitable for large pumps, fans, blowers, conveyors, material-handling machinery, mining equipment, water-treatment systems, cement-processing machinery, and other large industrial rotating equipment.

The model uses Frame 8 construction, forced-air cooling, an IP54 / NEMA Type 12 packaged enclosure, EMC filtering, AC input with precharge, and an embedded EtherNet/IP communication interface.

The AN0 configuration is associated with a blank/no-HIM arrangement and a removed common-mode capacitor jumper.

This particular configuration is therefore intended more toward centralized industrial-control installations where the drive is managed through the plant control system rather than requiring a dedicated local operator interface on the drive itself.

---

5. High-Power 710 A Configuration

The most important characteristic of the 20G1AJD710AN0NNNNN is its high current capability.

At approximately 710 A, this drive is intended for motors substantially larger than those normally served by compact or mid-range industrial VFDs.

The drive’s three principal duty classifications are:

• 650 HP Light Duty
• 600 HP Normal Duty
• 450 HP Heavy Duty

The different ratings allow the same basic drive platform to be applied to different mechanical load profiles.

A centrifugal pump or large fan with a relatively smooth torque requirement may be evaluated using the Light-Duty rating.

A conveyor or process machine with moderate overload requirements may be evaluated using the Normal-Duty rating.

A high-torque or cyclically loaded machine may need to be evaluated using the Heavy-Duty rating.

The correct selection should always be based on actual motor current and load characteristics rather than horsepower alone.

---

6. Light-Duty Rating

The approximately 650 HP Light-Duty rating makes this drive particularly suitable for large variable-torque loads.

Typical examples include:

• Large centrifugal pumps
• Large ventilation fans
• Cooling-water pumps
• Industrial blowers
• HVAC equipment
• Cooling towers
• Process-air systems

Variable-torque applications generally benefit from the ability to reduce motor speed as process demand decreases.

For these applications, the 710 A configuration provides a substantial operating range.

---

7. Normal-Duty Rating

The approximately 600 HP Normal-Duty rating provides a higher level of application flexibility for industrial machinery with more substantial loading requirements.

Normal-Duty applications may include:

• Large conveyors
• Process pumps
• Material-handling systems
• Industrial fans
• Large compressors
• Production machinery
• Processing equipment

The approximately 617 A continuous Normal-Duty rating provides a useful reference point when matching the drive to the motor nameplate current.

The overload capability also provides additional short-duration current for acceleration and transient loading.

---

8. Heavy-Duty Rating

The approximately 450 HP Heavy-Duty rating is important for applications where torque demand is higher or overload conditions are more severe.

Potential applications include:

• Heavy conveyors
• Crushers
• Feeders
• High-inertia machinery
• Material-handling equipment
• Heavy process machinery
• Cyclic industrial equipment

Heavy-Duty selection should be based on the actual motor current, acceleration profile, load inertia, and mechanical torque requirements.

A motor’s nominal horsepower alone does not determine whether the Heavy-Duty rating is appropriate.

---

9. 480 VAC Three-Phase Input

The drive is designed for the 480 VAC three-phase industrial power class.

The input configuration is suitable for industrial power systems commonly used for large motors.

Because the drive is rated at approximately 710 A, the upstream power system requires careful engineering.

Important considerations include:

• Transformer capacity
• Short-circuit current
• Input disconnect equipment
• Protective devices
• Incoming conductor size
• Grounding arrangement
• Voltage drop
• Harmonic effects
• Power quality
• Motor-cable arrangement

The drive should be incorporated into the electrical distribution design as a major power-consuming component.

---

10. AC Input with Precharge

The drive uses an AC input with precharge.

Precharge is particularly important in a high-power drive because the DC bus contains substantial energy-storage components.

When the drive is energized, the precharge system manages the initial charging process.

This reduces the uncontrolled charging current that would otherwise be associated with the DC bus capacitors.

The catalog configuration does not include dedicated DC input terminals.

This makes the unit particularly suitable for conventional AC-fed motor-control installations.

---

11. EMC Filter

The 20G1AJD710AN0NNNNN includes an EMC filter configuration.

Large PWM drives can generate high-frequency electrical noise as the power semiconductors switch rapidly.

The EMC filtering arrangement helps control conducted interference within the electrical installation.

This can be particularly valuable in plants containing:

• PLC systems
• Industrial Ethernet
• Analog control loops
• Instrumentation
• Encoders
• Distributed I/O
• Process transmitters
• HMI systems
• Measurement equipment

However, the filter is only one part of the complete EMC strategy.

Correct grounding, motor-cable selection, shielding, cable separation, cabinet construction, and installation practices remain essential.

---

12. CM Jumper Removed

The AN0 configuration identifies a configuration with the common-mode capacitor jumper removed.

This is an important electrical detail.

The common-mode capacitor configuration affects how the drive interacts with the grounding system and incoming power distribution.

It can be particularly relevant when the drive is installed on:

• Ungrounded systems
• Impedance-grounded systems
• Special transformer arrangements
• Systems with specific grounding requirements
• Industrial power systems with unusual neutral configurations

The common-mode configuration should therefore be checked against the actual plant power system before installation.

The related JN0 versions use the opposite common-mode jumper configuration, which is one reason the catalog number should not be shortened when ordering or replacing the drive.

---

13. Embedded EtherNet/IP

The drive includes embedded EtherNet/IP communication.

This allows the drive to be integrated into an industrial Ethernet control architecture.

Typical data exchanged between the drive and a PLC or controller can include:

• Run command
• Stop command
• Speed reference
• Output frequency
• Motor current
• Drive status
• Fault status
• Alarm status
• Diagnostic information
• Operating mode
• Parameter information

This is particularly valuable in large plants where many drives are controlled from a central automation system.

A centralized PLC can coordinate multiple drives while receiving real-time operating information from each drive.

---

14. Blank / No HIM Configuration

The AN0 version is configured as Blank / No HIM.

This means the standard catalog configuration does not include a dedicated local Human Interface Module.

This arrangement can be useful when the drive is installed in a centralized electrical room and controlled primarily through the plant automation system.

It can also be appropriate where operators do not need routine local access to the drive.

Commissioning and maintenance can instead be performed through suitable engineering tools and the industrial control system.

If a project requires frequent local parameter adjustment or operator interaction, a different catalog configuration with an appropriate HIM may be more suitable.

---

15. Frame 8 Construction

The drive uses Frame 8 construction.

Frame 8 is designed for high-current industrial drive applications.

The large frame provides physical space for:

• High-current power components
• DC bus structures
• Switching devices
• Cooling equipment
• Power terminals
• Control electronics
• Internal protection components
• Airflow channels

Because of its size, this drive should be considered a major electrical installation.

It requires appropriate planning for transportation, lifting, floor space, ventilation, cable routing, service access, and electrical clearances.

---

16. Enclosure Rating

The drive uses an IP54 / NEMA Type 12 packaged enclosure configuration.

This enclosure arrangement is intended for industrial environments where protection from dust and other common contaminants is required.

Typical installation areas include:

• Manufacturing plants
• Industrial electrical rooms
• Pump stations
• Water-treatment plants
• Cement plants
• Mining facilities
• Material-handling areas
• Process plants
• Utility installations

The enclosure rating does not eliminate the need for environmental engineering.

Temperature, humidity, corrosive substances, conductive dust, altitude, vibration, and airflow must still be considered.

---

17. Cooling System

The 20G1AJD710AN0NNNNN uses forced-air cooling.

At a current rating of approximately 710 A, heat management is a significant part of the installation design.

The cooling system removes heat generated by the power semiconductors and other internal components.

Adequate airflow helps maintain appropriate operating temperatures and reduces thermal stress.

The installation should prevent:

• Blocked air passages
• Hot-air recirculation
• Excessive ambient temperature
• Dust accumulation
• Restricted exhaust airflow
• Contaminated cooling air

For installations with several large drives, the electrical-room HVAC system should be designed to handle the combined heat load.

---

18. Dimensions and Weight

Mechanical Parameter	Approximate Specification
Catalog Number	20G1AJD710AN0NNNNN
Height	2477 mm
Width	600 mm
Depth	800 mm
Approximate Weight	644 kg
Frame	Frame 8
Enclosure	IP54 / NEMA Type 12
Cabinet Style	800 mm Deep MCC Style
Cooling	Forced Air
Mounting	Floor-Mounted
Handling Category	Heavy Industrial Equipment

The dimensions and weight should be used as engineering planning values rather than as a substitute for the final mechanical drawing.

At approximately 644 kg, the drive requires serious consideration of transportation and lifting.

The installation route should be checked before delivery, including:

• Door dimensions
• Corridor width
• Floor loading
• Turning radius
• Lifting equipment
• Final cabinet location
• Maintenance access

The approximately 2.5 m height also needs to be considered during building-layout planning.

---

19. Main Industrial Applications

---

20. Advantages of the 20G1AJD710AN0NNNNN

20G1AJD710AN0NNNNN – High Current Capacity

The approximately 710 A Light-Duty current rating provides substantial capacity for large 480 VAC motors.

This is one of the primary reasons to select this model over smaller PowerFlex configurations.

---

650 HP Light-Duty Capability

The approximately 650 HP Light-Duty rating provides considerable capacity for large variable-torque applications.

This is particularly useful for large pumps and fans.

---

600 HP Normal-Duty Capability

The approximately 600 HP Normal-Duty rating allows the drive to be used for substantial industrial machinery where the motor experiences a more demanding load profile.

---

450 HP Heavy-Duty Capability

This makes the drive suitable for a range of heavy industrial machinery when the actual motor current and overload requirements remain within the specified limits.

---

Embedded EtherNet/IP

Embedded EtherNet/IP is a major advantage in PLC-based automation systems.

It allows the drive to participate directly in the plant communication network.

This reduces the need for separate communication hardware for basic network integration.

---

IP54 / NEMA Type 12 Packaging

The packaged enclosure provides useful environmental protection for industrial applications.

This is especially valuable in environments where a completely open drive installation would be inappropriate.

---

EMC Filtering

Forced-air cooling avoids the complexity of a dedicated liquid cooling circuit.

For many industrial plants, this makes the system easier to install and maintain.

---

High-Power Frame 8 Platform

Frame 8 construction provides the physical and thermal capacity necessary for high-current operation.

It is designed specifically for large industrial motor applications.

---

Centralized Control Compatibility

The blank/no-HIM configuration can be advantageous where the drive is intended to operate under centralized PLC or SCADA control.

It avoids installing a local operator interface where one is not required.

---

21. Five Recommended Models in the Same Series

The following models are closely related to the 20G1AJD710AN0NNNNN and are useful for selecting a different current or horsepower capacity within the same 480 VAC PowerFlex 755 range.

Model	Voltage	Current	LD Rating	ND Rating	HD Rating	Frame	General Configuration
20G1AJD485AN0NNNNN	480 VAC	485 A	450 HP	400 HP	350 HP	8	Air Cooled, IP54/NEMA 12, EMC Filter, CM Jumper Removed
20G1AJD545AN0NNNNN	480 VAC	545 A	500 HP	450 HP	350 HP	8	Air Cooled, IP54/NEMA 12, EMC Filter, CM Jumper Removed
20G1AJD617AN0NNNNN	480 VAC	617 A	600 HP	500 HP	400 HP	8	Air Cooled, IP54/NEMA 12, EMC Filter, CM Jumper Removed
20G1AJD710AN0NNNNN	480 VAC	710 A	650 HP	600 HP	450 HP	8	Air Cooled, IP54/NEMA 12, EMC Filter, CM Jumper Removed
20G1AJD740AN0NNNNN	480 VAC	740 A	700 HP	650 HP	500 HP	8	Air Cooled, IP54/NEMA 12, EMC Filter, CM Jumper Removed

These five models form a closely matched selection group.

The 485 A and 545 A versions are appropriate when the motor current is lower.

The 617 A version provides a 600 HP Light-Duty rating.

The 710 A version increases the Light-Duty rating to approximately 650 HP.

The 740 A version provides approximately 700 HP Light-Duty capability.

The published 480 VAC selection data places these models together in the Frame 8 high-power range.

---

22. Five Related Models with Different Configurations

Model	Voltage	Current Class	LD HP	ND HP	HD HP	Frame	Main Difference
20G1AJD710AN4NNNNN	480 VAC	710 A	650 HP	600 HP	450 HP	8	AN4 operator-interface configuration
20G1AJD710JN0NNNNN	480 VAC	710 A	650 HP	600 HP	450 HP	8	JN0 CM-jumper configuration
20G1AJD710JN4NNNNN	480 VAC	710 A	650 HP	600 HP	450 HP	8	JN4 configuration
20G1AJD740AN0NNNNN	480 VAC	740 A	700 HP	650 HP	500 HP	8	Higher-current configuration
20G1AJD617AN0NNNNN	480 VAC	617 A	600 HP	500 HP	400 HP	8	Lower-current configuration

These models demonstrate the importance of the complete catalog number.

The first part of the catalog number can be very similar while the final configuration changes the HIM arrangement, common-mode capacitor configuration, or current rating.

---

23. Five Popular Allen-Bradley Models for Broader Comparison

Model	Product Series	Voltage Class	Approx. Current / Power Class	Drive Type	Typical Application
25B-D030N114	PowerFlex 525	480 VAC class	30 A class	Compact AC Drive	Pumps, fans, conveyors, machinery
25C-D030N114	PowerFlex 527	480 VAC class	30 A class	Networked AC Drive	PLC-based machine automation
20G1AGE053JA0NNNNN	PowerFlex 755	480 VAC class	High-power class	Air-Cooled AC Drive	Large industrial motors
20G1AGC260JN0NNNNN	PowerFlex 755	400 VAC class	260 A class	Air-Cooled AC Drive	Process machinery and large motors
20G1AND302JA0NNNNN	PowerFlex 755	480 VAC class	302 A class	Air-Cooled AC Drive	Pumps, fans, conveyors and process equipment

These five models cover a wider portion of the industrial AC-drive range.

The PowerFlex 525 and PowerFlex 527 configurations are more appropriate for compact and medium-sized machines.

The PowerFlex 755 configurations are better suited to larger motors and more demanding process equipment.

For an application requiring approximately 710 A at 480 VAC, the 20G1AJD710AN0NNNNN is positioned substantially above compact machine-drive products.

---

24. Comparison with the 617 A Version

A useful comparison is the closely related 20G1AJD617AN0NNNNN.

Parameter	20G1AJD617AN0NNNNN	20G1AJD710AN0NNNNN
Voltage	480 VAC	480 VAC
Current	617 A	710 A
LD Rating	600 HP	650 HP
ND Rating	500 HP	600 HP
HD Rating	400 HP	450 HP
Frame	8	8
Cooling	Air Cooled	Air Cooled
Enclosure	IP54 / NEMA Type 12	IP54 / NEMA Type 12
EMC Filter	Yes	Yes
CM Jumper	Removed	Removed
Dynamic Braking	None	None
HIM	Blank / No HIM	Blank / No HIM
EtherNet/IP	Embedded	Embedded

The 710 A version provides a meaningful increase in current and horsepower capacity over the 617 A model.

For a motor operating close to the upper range of a 617 A configuration, the 710 A model can provide additional capacity.

However, oversizing should not be done automatically.

The final selection should be based on motor full-load current, duty cycle, overload requirement, acceleration profile, ambient conditions, and application requirements.

---

25. Comparison with the 740 A Version

The 20G1AJD740AN0NNNNN is the next higher-current model in this closely related group.

Parameter	20G1AJD710AN0NNNNN	20G1AJD740AN0NNNNN
Voltage	480 VAC	480 VAC
Current	710 A	740 A
LD Rating	650 HP	700 HP
ND Rating	600 HP	650 HP
HD Rating	450 HP	500 HP
Frame	8	8
Cooling	Air Cooled	Air Cooled
Enclosure	IP54 / NEMA Type 12	IP54 / NEMA Type 12
EMC Filter	Yes	Yes
CM Jumper	Removed	Removed
Dynamic Braking	None	None
HIM	Blank / No HIM	Blank / No HIM
EtherNet/IP	Embedded	Embedded

The 740 A model provides additional electrical capacity.

For a motor application that is close to the 710 A limit, the 740 A configuration may provide a more appropriate engineering margin.

Again, the final selection should be based on the motor nameplate current and actual load profile rather than horsepower alone.

---

26. Typical Control Architecture

A typical industrial installation can be organized as:

PLC / Industrial Controller → EtherNet/IP Network → 20G1AJD710AN0NNNNN → Large Three-Phase AC Motor

The PLC can issue:

• Start commands
• Stop commands
• Speed references
• Process setpoints
• Fault reset commands
• Operating-mode commands

The drive can return:

• Running status
• Output frequency
• Motor current
• Drive status
• Fault information
• Alarm information
• Diagnostic information

This architecture is especially useful for large plants where multiple motors need to be coordinated.

---

27. Maintenance Considerations

The 20G1AJD710AN0NNNNN is a high-power industrial drive and should be incorporated into a structured maintenance program.

Maintenance activities may include:

• Cooling-fan inspection
• Airflow inspection
• Cabinet cleanliness checks
• Power-connection inspection
• Grounding inspection
• Control-wiring inspection
• Network-communication checks
• Fault-history review
• Environmental inspection
• Motor-cable inspection
• Ventilation-system inspection

Dust and contamination can be particularly problematic for forced-air cooling systems.

A clean electrical environment helps maintain adequate cooling performance and reduces thermal stress on the drive.

---

28. Installation Considerations

Electrical Installation

The incoming power system must be compatible with the drive’s 480 VAC three-phase requirements.

The upstream protective equipment should be correctly coordinated with the drive and the facility’s short-circuit conditions.

Grounding

The grounding arrangement should be verified before commissioning.

The AN0 configuration uses a removed CM jumper, so the relationship between the drive configuration and the plant grounding system should be checked carefully.

Motor Cable

The motor cable should be selected according to current, voltage, cable length, installation environment, grounding, insulation, and applicable electrical standards.

Ventilation

Adequate cooling airflow is essential.

The drive should not be installed where hot exhaust air can circulate back into the cooling intake.

Mechanical Installation

Because the equipment is approximately 644 kg, proper lifting and handling equipment should be provided.

The floor and cabinet arrangement should be capable of supporting the installed equipment.

---

---

31. Product Status and Replacement Consideration

The 20G1AJD710AN0NNNNN has been discontinued.

The listed direct replacement is 20G1AJD710JN0NNNNN.

For an existing installation, this distinction is important.

A replacement project should not be based only on the 710 A current rating.

The engineer should compare:

• Voltage
• Current
• Duty rating
• Enclosure
• Frame
• Communication
• HIM arrangement
• CM jumper configuration
• EMC filtering
• Dynamic-braking requirements
• Dimensions
• Power terminals
• Control wiring
• Motor-cable arrangement

The direct replacement designation is useful, but the actual installation should still be checked against the complete equipment configuration.

---

32. Catalog Number Interpretation

The complete catalog number is:

20G1AJD710AN0NNNNN

The 710 portion identifies the high-current class.

The D section identifies the 480 VAC class within the relevant PowerFlex 755 catalog structure.

The A configuration is associated with the removed CM-jumper arrangement.

The N0 configuration corresponds to the blank/no-HIM arrangement.

The complete catalog number therefore carries considerably more information than the simple description “PowerFlex 755, 710 A.”

This is why purchasing and replacement documents should retain the complete catalog number.

---

33. Why the Complete Model Number Matters

Consider these closely related configurations:

20G1AJD710AN0NNNNN

All four are associated with the same general 710 A PowerFlex 755 platform.

However, they are not necessarily identical configurations.

Differences can involve the HIM arrangement and common-mode capacitor configuration.

For replacement work, selecting only “710 A PowerFlex 755” can therefore result in an incorrect configuration.

The complete catalog number should be used wherever possible.

36. Final Product Assessment

The Allen-Bradley 20G1AJD710AN0NNNNN PowerFlex 755 AC Drive is a large industrial variable-frequency drive intended for high-capacity three-phase motor applications.

Its approximately 710 A current rating and 650 HP Light-Duty / 600 HP Normal-Duty / 450 HP Heavy-Duty capability make it suitable for a wide range of large industrial machines.

The drive’s Frame 8 architecture, IP54 / NEMA Type 12 packaged construction, forced-air cooling, EMC filtering, AC precharge, embedded EtherNet/IP, and blank/no-HIM configuration make it particularly appropriate for centralized industrial control systems.

Large pumps and fans are among the strongest application areas because their variable-speed requirements can make effective use of the Light-Duty rating.

Large conveyors, process machinery, mining equipment, material-handling systems, and other demanding machines can also benefit from the drive’s Normal-Duty and Heavy-Duty capabilities.

The AN0 configuration is an important part of the catalog identity.

It identifies a configuration with the CM jumper removed and no standard HIM, distinguishing it from related AN4, JN0, and JN4 configurations.

The drive’s physical size and weight also need to be considered during project planning.

An approximate 2477 × 600 × 800 mm envelope and approximately 644 kg equipment weight mean that transportation, lifting, floor loading, ventilation, cable routing, and maintenance access must be planned before installation.

For an existing system, the complete catalog number should be retained in procurement and maintenance records.

For new selection or replacement work, the motor’s actual full-load current, duty cycle, overload requirements, acceleration profile, power-system grounding, enclosure requirements, and communication architecture should all be checked before finalizing the drive.

Overall, the 20G1AJD710AN0NNNNN is a high-capacity PowerFlex 755 configuration aimed at large industrial motor-control applications where high current, substantial horsepower capability, industrial enclosure protection, and integrated network communication are required.
