The Allen-Bradley 20G11TD710JN0NNNNN is a high-power PowerFlex 755 AC Drive designed for large industrial motor-control applications where high current capacity, flexible speed control, network integration, and reliable operation are required.
This model belongs to the PowerFlex 755 family and is configured as an air-cooled, floor-mount/open-frame drive in Frame 8. It is designed for three-phase 480 VAC systems and provides a substantial 710 A class output rating, making it suitable for large motors and demanding industrial machinery.
The drive incorporates embedded EtherNet/IP communication, allowing it to integrate directly into modern industrial automation architectures. This makes it practical for applications where the variable-frequency drive needs to exchange operating data, commands, status information, alarms, and diagnostic information with a PLC, controller, HMI, SCADA system, or plant-level automation network.
The 20G11TD710JN0NNNNN configuration includes AC input with DC terminals, forced-air cooling, EMC filtering, and the preferred common-mode jumper configuration. Dynamic braking is not included in this base configuration, and the catalog configuration is supplied without a mounted HIM.
The model is intended for large-scale industrial installations rather than small standalone motor applications. Its Frame 8 construction, high current capability, and floor-mount architecture make it particularly appropriate for large pumps, fans, conveyors, compressors, material-handling systems, process equipment, and other high-power machinery.

One important point when specifying the 20G11TD710JN0NNNNN is that the 710 A figure should not simply be interpreted as a single motor horsepower rating under every operating condition.
PowerFlex drives of this size are normally selected according to the application’s duty cycle. The same drive can support different motor power levels depending on whether the application is classified as Light Duty, Normal Duty, or Heavy Duty.
For this model, the published ratings are approximately:
| Duty Classification | Output Rating | Approx. Motor Power |
|---|---|---|
| Light Duty (LD) | 710 A class | 650 HP / approx. 485 kW |
| Normal Duty (ND) | 617–710 A class depending on rating convention | 600 HP / approx. 448 kW |
| Heavy Duty (HD) | 545 A class | 450 HP / approx. 336 kW |
For engineering selection, the duty classification should always be matched to the actual motor load profile, overload requirement, acceleration requirement, ambient conditions, and process operating cycle.
The 600 HP Normal Duty rating is especially useful for large continuous-process applications where the motor operates for long periods at relatively stable loading.
The lower Heavy Duty horsepower rating reflects the increased thermal and overload demands associated with applications requiring greater short-term torque and overload capability.

The AC input with precharge arrangement is important for a drive of this size because the input section has to manage the initial charging of the DC bus before normal high-power operation begins.
The presence of DC terminals also provides additional flexibility for system architectures where DC-bus connections or common DC-bus arrangements are relevant.
For large industrial equipment, this architecture can be useful when several drives or power-conversion components are integrated into a coordinated power system.
The 20G11TD710JN0NNNNN includes embedded EtherNet/IP communication.
This is one of the major advantages of the PowerFlex 755 platform because the drive can become an active component of the plant automation network instead of functioning only as an isolated motor controller.
Typical network functions include:
In a large production line, this allows the drive to be treated as part of the overall control architecture.
For example, a PLC can command the drive to accelerate a conveyor motor, monitor the actual operating speed, detect a fault condition, and initiate an appropriate shutdown sequence without requiring a separate hardwired control arrangement for every operating parameter.
The drive uses a forced-air cooling system.
For a high-current Frame 8 drive, thermal management is a critical part of the installation design.
Large industrial drives generate significant heat during power conversion. The cooling system therefore needs adequate airflow and appropriate cabinet or electrical-room ventilation.
The forced-air configuration is well suited to industrial installations where the drive is installed in a properly engineered electrical room, control cabinet, MCC environment, or dedicated drive enclosure.
The cooling system should not be treated as an afterthought. Airflow paths, ambient temperature, dust accumulation, cabinet ventilation, filter maintenance, and spacing around the equipment can all influence long-term drive reliability.
Because the 20G11TD710JN0NNNNN is a large Frame 8 floor-mount/open-frame drive, its mechanical installation requirements are considerably different from compact wall-mounted PowerFlex models.
The following values should be treated as engineering reference values rather than guaranteed shipping dimensions. Actual overall dimensions and weight can vary according to the final configuration, mounting arrangement, accessories, enclosure, and installation architecture.
| Mechanical Parameter | Approximate / Reference Value |
|---|---|
| Model | 20G11TD710JN0NNNNN |
| Frame Size | Frame 8 |
| Approx. Width | 720 mm |
| Approx. Height | 2,185 mm |
| Approx. Depth | 650 mm |
| Approx. Weight | 335 kg |
| Mounting Style | Floor Mount |
| Construction | Open Frame |
| Cooling | Forced Air |
| Installation Space | Large industrial electrical equipment area |
| Handling Requirement | Heavy lifting / appropriate installation equipment required |
The approximate 335 kg weight means that normal manual handling is not appropriate.
The installation should be planned around the available lifting equipment, floor loading, mounting structure, cable-entry arrangement, ventilation requirements, and service access.
For final engineering, transportation, panel fabrication, and installation work, the manufacturer’s dimension drawing and the exact configured product documentation should take precedence over the approximate dimensions listed above.
The catalog number 20G11TD710JN0NNNNN contains configuration information describing the drive’s electrical and mechanical characteristics.
The important configuration elements can be summarized as follows:
| Configuration Item | Description |
|---|---|
| Product Family | PowerFlex 755 |
| Drive Type | Air-Cooled AC Drive |
| Voltage Class | 480 VAC |
| Phase | Three Phase |
| Current Class | 710 A |
| Frame | Frame 8 |
| Input | AC with Precharge |
| DC Terminals | Yes |
| Filtering | Filtered |
| CM Configuration | Jumper Installed |
| Cooling | Forced Air |
| Dynamic Braking | None |
| HIM | Blank / No HIM |
| Network | Embedded EtherNet/IP |
The J configuration for the filtering/common-mode arrangement is an important distinction from earlier configurations that used a removed CM jumper.
For applications where EMC behavior and common-mode considerations are important, the correct filtering and jumper configuration should be maintained according to the installation requirements.
The 20G11TD710JN0NNNNN is well suited to large conveyor systems requiring substantial motor power.
Large conveyors in mining, bulk material handling, ports, warehouses, steel processing, cement plants, and heavy manufacturing facilities can require hundreds of horsepower.
A variable-frequency drive allows the conveyor motor to accelerate smoothly rather than receiving an abrupt full-voltage start.
This can reduce mechanical shock to gearboxes, couplings, belts, shafts, bearings, and conveyor structures.
The drive can also provide adjustable speed, allowing the production process to operate according to material flow and process requirements.
Large centrifugal and process pumps are another important application.
A drive can regulate pump speed according to process demand rather than forcing the pump to operate continuously at full speed.
This can improve process control and, depending on the system characteristics, reduce energy consumption.
Applications can include:
Large industrial fans and blowers can benefit significantly from variable-speed control.
Instead of operating a motor continuously at maximum speed and controlling airflow through mechanical dampers, the drive can adjust motor speed according to the required airflow.
Typical applications include:
Large compressors can require high motor power and controlled acceleration.
The PowerFlex 755 platform can be integrated into compressor control systems where variable-speed operation is required.
Potential applications include:
Compressor applications require careful consideration of acceleration, deceleration, minimum speed, torque requirements, and process control.
The drive can also be used in heavy-duty material-handling equipment.
Examples include:
The high current capacity gives the drive the ability to control large industrial motors while maintaining flexible speed control.
Mining equipment often requires high-power motor control, rugged electrical architecture, and centralized automation.
Applications may include:
The Frame 8 configuration is especially appropriate for large fixed industrial installations where high-power motors are involved.
Cement and aggregate production facilities use many large motors.
The drive can be applied to:
In these applications, motor speed frequently needs to be adjusted according to production conditions.
Large motors are common throughout steel and metal-processing facilities.
Potential applications include:
The ability to integrate the drive into an EtherNet/IP-based control architecture is useful in centralized production systems.
The drive can also be used in large auxiliary systems associated with power generation and utility installations.
Typical applications include:
These systems can benefit from adjustable motor speed and centralized diagnostic monitoring.
The most obvious advantage of the 20G11TD710JN0NNNNN is its high power capacity.
With a 710 A class rating and a 600 HP Normal Duty rating, the drive is intended for substantially larger motors than compact variable-frequency drives.
This makes it appropriate for large industrial equipment where a small-frame drive would simply not provide sufficient current capacity.
The drive is designed around large industrial motors.
The 650 HP Light Duty, 600 HP Normal Duty, and 450 HP Heavy Duty ratings provide flexibility for selecting the drive according to actual process loading.
This is particularly useful when engineers need to consider both continuous motor load and short-term overload requirements.
Embedded EtherNet/IP eliminates the need to treat communication as an entirely separate system.
The drive can communicate operating data and commands with compatible industrial control systems.
This can simplify automation architecture and improve access to drive diagnostics.
PowerFlex 755 drives are designed for integration into larger industrial control systems.
The 20G11TD710JN0NNNNN can be incorporated into equipment where drive control, process control, diagnostics, and supervisory functions are managed through a common automation platform.
The forced-air architecture provides active thermal management appropriate for a high-power industrial drive.
Proper ventilation and maintenance are still essential, but the cooling arrangement is designed for continuous industrial operation.
The AC input configuration with DC terminals provides additional flexibility for system design.
This can be valuable in installations where DC-bus architecture is part of the electrical design.
The filtered configuration helps support installations where electromagnetic compatibility is an important design consideration.
Correct grounding, cable selection, shielding, cabinet layout, and motor-cable practices remain important even when filtering is provided.
The Frame 8 design provides a practical mechanical platform for high-power installations.
Instead of attempting to package the drive into the small physical footprint associated with compact VFD products, the floor-mount architecture provides space for high-current power components, cooling equipment, wiring, and service access.
In a large plant, having the drive connected to the control network can make troubleshooting considerably easier.
Operators can monitor drive status from an HMI or supervisory system, while maintenance personnel can use available diagnostic information to identify problems more quickly.
The 20G11TD710JN0NNNNN is a large industrial power device and should be treated accordingly during installation.
The electrical installation should consider:
Because the unit weighs hundreds of kilograms, the installation plan should include appropriate mechanical handling equipment.
The final cabinet design should also account for the heat generated by the drive and its cooling system.
| Application Type | Suitability | Main Reason |
|---|---|---|
| Large Conveyors | Excellent | High current and adjustable speed |
| Large Pumps | Excellent | Variable-speed process control |
| Large Fans | Excellent | High-power motor control |
| Blowers | Excellent | Adjustable airflow |
| Compressors | Very Good | Large motor and controlled acceleration |
| Crushers | Very Good | High-power industrial motor control |
| Mining Equipment | Excellent | High-power fixed installation |
| Cement Equipment | Excellent | Large motor applications |
| Steel Processing | Very Good | Large-scale motor automation |
| Material Handling | Excellent | High-power motor control |
| Utility Systems | Very Good | Networked motor control |
| Small Machines | Poor Fit | Drive is considerably oversized |
The last point is important: this is not a compact general-purpose VFD.
Using a Frame 8, 710 A-class drive for a small motor would normally be economically and physically impractical.
Its value is realized when the application genuinely requires large motor power and the associated industrial control capabilities.
The following models are closely related to the requested drive and belong to the same PowerFlex 755 floor-mount family.
They are useful when selecting a lower or higher current rating for the same general 480 VAC industrial application.
| Recommended Model | Frame | Voltage | LD Rating | ND Rating | HD Rating | Approx. LD HP | Approx. ND HP | Approx. HD HP |
|---|---|---|---|---|---|---|---|---|
| 20G11TD430JN0NNNNN | 8 | 480 VAC, 3 PH | 485 A | 430 A | 370 A | 400 HP | 350 HP | 300 HP |
| 20G11TD485JN0NNNNN | 8 | 480 VAC, 3 PH | 545 A | 485 A | 414 A | 450 HP | 400 HP | 350 HP |
| 20G11TD545JN0NNNNN | 8 | 480 VAC, 3 PH | 590 A | 545 A | 454 A | 500 HP | 450 HP | 350 HP |
| 20G11TD617JN0NNNNN | 8 | 480 VAC, 3 PH | 710 A | 617 A | 485 A | 600 HP | 500 HP | 400 HP |
| 20G11TD740JN0NNNNN | 8 | 480 VAC, 3 PH | 800 A | 740 A | 617 A | 700 HP | 650 HP | 500 HP |
These models are particularly useful when the motor size is close to the boundary between two drive ratings.
For example, the 20G11TD617JN0NNNNN provides a lower power option within the same Frame 8 family, while the 20G11TD740JN0NNNNN provides additional current and horsepower capacity.
This makes the group useful for standardizing large-drive installations across a plant.
The following models are not direct replacements for the 20G11TD710JN0NNNNN. They are popular models from other Allen-Bradley PowerFlex families and can be considered when the application requires a different power range, physical size, or drive architecture.
| Model | Product Family | Voltage Class | Phase | Current Class | Typical Power Range | Frame / Form | Typical Application |
|---|---|---|---|---|---|---|---|
| 25B-D024N114 | PowerFlex 525 | 480 VAC Class | 3 PH | 24 A class | Small/medium motors | Compact | General industrial machinery |
| 25B-D6P0N114 | PowerFlex 525 | 480 VAC Class | 3 PH | 6 A class | Small motors | Compact | Pumps, fans, conveyors |
| 20F11NC3P4JA0NNNNN | PowerFlex 753 | 480 VAC Class | 3 PH | 3.4 A class | Small motor range | Compact/Modular | Machine and process control |
| 20F11ND077AA0NNNNN | PowerFlex 753 | 480 VAC Class | 3 PH | 77 A class | Medium/large motors | Modular | Industrial machinery |
| 25C-D043N114 | PowerFlex 523 | 480 VAC Class | 3 PH | 43 A class | Medium motor range | Compact | General-purpose motor control |
These products serve very different application sizes.
The PowerFlex 523 and PowerFlex 525 families are generally more appropriate for compact machinery and smaller motors.
The PowerFlex 753 family sits closer to the industrial automation space of the PowerFlex 755 family and provides a useful option for applications where the power requirement is substantially lower than the 710 A class.
The 20G11TD710JN0NNNNN, by comparison, is firmly positioned in the large industrial-drive category.
| Model | Voltage | Frame | LD Current | ND Current | HD Current | LD HP | ND HP | HD HP |
|---|---|---|---|---|---|---|---|---|
| 20G11TD430JN0NNNNN | 480 VAC, 3 PH | 8 | 485 A | 430 A | 370 A | 400 | 350 | 300 |
| 20G11TD485JN0NNNNN | 480 VAC, 3 PH | 8 | 545 A | 485 A | 414 A | 450 | 400 | 350 |
| 20G11TD545JN0NNNNN | 480 VAC, 3 PH | 8 | 590 A | 545 A | 454 A | 500 | 450 | 350 |
| 20G11TD617JN0NNNNN | 480 VAC, 3 PH | 8 | 710 A | 617 A | 485 A | 600 | 500 | 400 |
| 20G11TD710JN0NNNNN | 480 VAC, 3 PH | 8 | 765 A | 710 A | 545 A | 650 | 600 | 450 |
| 20G11TD740JN0NNNNN | 480 VAC, 3 PH | 8 | 800 A | 740 A | 617 A | 700 | 650 | 500 |
This table makes the sizing progression easier to understand.
The 20G11TD710JN0NNNNN sits near the upper end of the standard Frame 8 PowerFlex 755 floor-mount range.
If the motor requires approximately 600 HP under Normal Duty conditions, this model provides a strong fit.
If the application requires approximately 650 HP Normal Duty or higher current capacity, the 20G11TD740JN0NNNNN should be evaluated instead.
If the motor is closer to 500 HP Normal Duty, the 20G11TD617JN0NNNNN may provide a more appropriately sized solution.
The 20G11TD710AN0NNNNN and 20G11TD710JN0NNNNN are closely related configurations.
The important distinction is the common-mode jumper/filter configuration.
| Parameter | 20G11TD710AN0NNNNN | 20G11TD710JN0NNNNN |
|---|---|---|
| Product Family | PowerFlex 755 | PowerFlex 755 |
| Voltage | 480 VAC, 3 PH | 480 VAC, 3 PH |
| Current Class | 710 A | 710 A |
| Frame | 8 | 8 |
| Cooling | Forced Air | Forced Air |
| Input | AC with Precharge and DC Terminals | AC with Precharge and DC Terminals |
| Filtering | Filtered | Filtered |
| CM Jumper | Removed | Installed |
| Dynamic Braking | None | None |
| HIM | Blank / No HIM | Blank / No HIM |
| General Architecture | PowerFlex 755 | PowerFlex 755 |
The J configuration is the preferred current configuration with the CM jumper installed.
This distinction matters when replacing an older drive or standardizing drive configurations across a plant.
A replacement should not be selected based only on the first several characters of the catalog number. The complete catalog number should be checked because filtering, jumper configuration, braking, HIM, enclosure, and other options can affect system compatibility.
The main strength of the 20G11TD710JN0NNNNN is not simply its large current rating.
Its real value comes from combining high-power motor control with a modern industrial automation architecture.
A large production system often needs much more than simply turning a motor on and off.
The control system may need to regulate speed, coordinate multiple motors, monitor current, detect faults, record operating conditions, communicate with PLCs, and provide operators with diagnostic information.
The PowerFlex 755 architecture is designed for this type of environment.
The embedded EtherNet/IP capability makes the drive a natural component of an integrated industrial control system.
The Frame 8 design also makes the drive suitable for large electrical installations where the motor power is beyond the range of compact wall-mounted drives.
For a drive of this size, preventive maintenance is important.
The forced-air cooling system should be inspected regularly.
Maintenance personnel should pay attention to:
Large industrial drives should be incorporated into the plant’s preventive-maintenance program rather than serviced only after a failure occurs.

The Allen-Bradley 20G11TD710JN0NNNNN PowerFlex 755 AC Drive is a high-capacity industrial variable-frequency drive intended for large three-phase motor applications.
Its combination of 480 VAC operation, 710 A class capacity, Frame 8 construction, forced-air cooling, AC input with DC terminals, EMC filtering, installed CM jumper, and embedded EtherNet/IP communication gives it the characteristics expected from a large industrial automation drive.
The 600 HP Normal Duty rating makes it particularly attractive for substantial continuous-duty equipment, while the Light Duty and Heavy Duty ratings allow the same drive platform to be evaluated against different application load profiles.
The drive is best suited to installations where motor power, process control, automation integration, and long-term industrial maintainability are all important considerations.
For large conveyors, pumps, fans, compressors, crushers, mining systems, cement equipment, material-handling machinery, and other high-power process equipment, the PowerFlex 755 platform provides a scalable solution that can be integrated into a larger industrial control system.
The Frame 8 / approximately 335 kg physical scale should be taken seriously during project planning. This is a large floor-mounted industrial drive rather than a compact panel-mounted VFD, so electrical-room layout, cabinet construction, cooling, lifting, cable routing, service clearance, and floor loading should all be considered during installation.
For final procurement and mechanical engineering, the exact configured product drawing should be used to confirm dimensions, weight, clearances, mounting points, cable-entry requirements, and accessory configuration.
Overall, the 20G11TD710JN0NNNNN is a strong choice for high-power industrial motor control where approximately 600 HP Normal Duty capability is required together with networked automation and the broader capabilities of the PowerFlex 755 platform.
