Allen-Bradley 20G11TD710AN0NNNNN PowerFlex 755 AC Drive – Detailed Product Specifications, Applications, Advantages and Related Models

1. Product Introduction

The Allen-Bradley 20G11TD710AN0NNNNN is a high-power PowerFlex 755 AC Drive designed for large industrial motor-control applications where high current capacity, dependable speed regulation, flexible motor control, and integration with industrial automation systems are required.

This model belongs to the PowerFlex 755 series and is designed for a 480 VAC, three-phase electrical system. It uses a large Frame 8 construction and provides a nominal drive current rating of 710 A.

The drive has three major application-duty ratings: approximately 650 HP for Light Duty, 600 HP for Normal Duty, and 450 HP for Heavy Duty. This combination makes it suitable for a wide range of large industrial machines, from high-volume pumping and ventilation equipment to large conveyors, compressors, material-handling systems, mining equipment, cement machinery, and other heavy industrial processes.

The 20G11TD710AN0NNNNN is an air-cooled PowerFlex 755 configuration with embedded Ethernet/IP, an AC input with precharge, DC terminals, filtered input configuration, and an open-type Frame 8 construction.

The catalog configuration also specifies CM jumper removed, no dynamic braking, and a blank/no-HIM configuration. These details are important because they define how the drive is integrated into the overall electrical and automation system.

This is a large industrial drive rather than a compact general-purpose inverter. At this power level, the drive should be considered as part of the complete electrical system, including the incoming power distribution, motor, motor cabling, grounding system, cabinet cooling, protection equipment, automation network, and mechanical load.

The horsepower figures are the primary catalog rating references. The corresponding kilowatt figures shown above are approximate conversions for convenient engineering comparison.

Actual drive selection should be based on motor full-load current, application duty, overload requirements, acceleration requirements, operating speed, ambient temperature, and mechanical load characteristics rather than relying on horsepower conversion alone.

5. Light-Duty Rating – 650 HP

The Light-Duty rating of the 20G11TD710AN0NNNNN is approximately 650 HP.

Light-Duty applications generally have relatively moderate overload requirements and a load profile that does not place severe sustained stress on the drive.

Large centrifugal pumps and fans are common examples.

For these types of loads, the drive can provide a large amount of available motor power while allowing the motor speed to be adjusted according to process requirements.

6. Normal-Duty Rating – 600 HP

The Normal-Duty rating is approximately 600 HP.

This is one of the most useful ratings for general industrial equipment.

A 600 HP Normal-Duty capability places this drive in a class suitable for very large motors used in:

• Large pumps
• Fans
• Blowers
• Conveyors
• Process machinery
• Industrial compressors
• Material-handling equipment
• Large production machinery

When the motor operates continuously and the load is relatively predictable, the Normal-Duty rating can provide a practical basis for drive selection.

7. Heavy-Duty Rating – 450 HP

The Heavy-Duty rating is approximately 450 HP.

Heavy-Duty applications are generally associated with greater overload requirements, higher starting torque, high inertia, frequent acceleration, or more severe cyclic operation.

Potential applications include:

• Heavy conveyors
• Crushers
• Large mixers
• Material-processing equipment
• High-inertia machinery
• Severe-duty production machinery
• Heavy material-handling systems

For these applications, the Heavy-Duty rating should be used when determining whether the drive has sufficient current and overload capability.

8. Physical Dimensions and Weight

The physical size of the 20G11TD710AN0NNNNN is an important consideration during installation.

Mechanical Parameter	Approximate Specification
Model	20G11TD710AN0NNNNN
Frame	Frame 8
Approx. Width	720 mm
Approx. Height	2185 mm
Approx. Depth	650 mm
Approx. Overall Dimensions	720 × 2185 × 650 mm
Approx. Weight	335 kg
Cooling	Forced Air
Construction	Open Type
Mounting	Heavy Industrial Mounting
Installation Area	Electrical Room / Large Cabinet
Handling	Mechanical Lifting Recommended

The dimensions and weight are best treated as approximate reference values for product planning.

The final mechanical envelope can vary according to the specific installation arrangement, cabinet design, ducting, mounting structure, options, and associated equipment.

For a project requiring precise cabinet dimensions, the final mechanical drawing should be used rather than relying solely on the approximate dimensions above.

At approximately 335 kg, the drive is heavy electrical equipment. Proper lifting, transportation, mounting, floor loading, service clearance, and cabinet structure should be considered before installation.

9. Frame 8 Construction

The 20G11TD710AN0NNNNN uses a Frame 8 PowerFlex 755 construction.

Frame 8 is intended for high-power applications and is substantially larger than compact drive frames.

The larger frame provides the physical and electrical capacity needed for high-current operation.

However, the larger size also means that the installation requires more attention to:

• Cabinet dimensions
• Power cable routing
• Cooling
• Ventilation
• Mechanical support
• Service access
• Lifting equipment
• Electrical clearances
• Heat dissipation

10. Forced-Air Cooling

The drive uses forced-air cooling.

Large power semiconductor devices generate considerable heat during operation. Removing this heat efficiently is essential for reliable operation.

The cooling system requires adequate air circulation around the drive.

The installation should therefore provide:

• Clean cooling air
• Adequate intake airflow
• Adequate exhaust airflow
• Correct cabinet ventilation
• Proper fan operation
• Sufficient service clearance
• Protection against excessive dust

Hot exhaust air should not be allowed to circulate back into the drive intake.

In dusty industrial environments, the condition of ventilation filters and airflow passages should be checked regularly.

11. Embedded Ethernet/IP Communication

The embedded Ethernet/IP capability is one of the major advantages of the PowerFlex 755 platform.

The 20G11TD710AN0NNNNN can be integrated into a larger industrial automation architecture.

A typical system may look like:

PLC → Ethernet/IP Network → PowerFlex 755 → Large Industrial Motor

The same network may also provide communication with:

• HMI
• SCADA
• Remote I/O
• Production-control systems
• Other drives
• Motion equipment
• Diagnostic systems

This architecture can reduce the need for isolated control wiring and can provide a more centralized approach to motor monitoring and control.

12. Industrial Communication Advantages

For large industrial facilities, communication is increasingly important.

A drive may need to provide information such as:

• Motor speed
• Output current
• Drive status
• Fault status
• Warning status
• Operating condition
• Commanded speed
• Actual speed
• Diagnostic information

Using Ethernet/IP communication allows the drive to become part of the plant’s overall automation strategy.

This is especially valuable when many large motors are distributed throughout a production process.

13. AC Input with Precharge

The catalog configuration specifies AC input with precharge.

The precharge system is important in large drives because the DC bus contains substantial capacitive energy storage.

During energization, the DC bus needs to be charged in a controlled manner.

This is particularly important for high-power equipment because the charging current and stored electrical energy are much greater than in small drives.

The precharge architecture is therefore an important part of the overall high-power drive design.

14. DC Terminals

The drive provides DC terminals.

These terminals can provide additional flexibility for system architecture.

They may be relevant in systems involving:

• Common DC bus concepts
• Coordinated drive systems
• DC-bus energy management
• Regenerative system architectures
• Multiple-drive arrangements

However, DC terminals should only be used according to the specific system design.

The existence of DC terminals does not mean that an external DC-bus system is required for normal operation.

15. Filtering Configuration

The 20G11TD710AN0NNNNN is configured as a filtered drive.

Input filtering can be an important consideration in industrial installations where electrical compatibility and conducted noise need to be controlled.

The actual EMC requirements of a system depend on:

• Motor cable length
• Cable construction
• Grounding
• Cabinet arrangement
• Power distribution
• Installation environment
• Other connected equipment

Therefore, filtering should be considered together with the complete installation rather than viewed as an isolated drive specification.

16. CM Jumper Removed

A specific characteristic of this catalog number is that the CM jumper is removed.

This is an important configuration detail.

The catalog number 20G11TD710AN0NNNNN belongs to the older AN configuration, while the closely related 20G11TD710JN0NNNNN uses a different CM-jumper configuration.

This difference matters when replacing a drive because the catalog number should not be selected based only on voltage, current, and horsepower.

Grounding, EMC, common-mode behavior, and the installation’s electrical architecture should also be considered.

17. Dynamic Braking

The base configuration specifies no dynamic braking.

This is particularly important for applications where the mechanical load can return energy to the drive during deceleration.

Examples include:

• High-inertia machines
• Hoists
• Rapidly decelerating conveyors
• Large rotating machinery
• Certain test machines
• Cyclic machinery

If significant regenerative energy is expected, the system may require an appropriate braking or regenerative-energy solution.

This should be determined during the application-engineering stage rather than after the drive has been installed.

18. No HIM Configuration

The model is configured as Blank / No HIM.

HIM refers to the Human Interface Module used for local drive interaction.

The no-HIM configuration can be advantageous in automated systems where operators normally interact with the machine through:

• PLC
• HMI
• SCADA
• Ethernet/IP
• Engineering software
• Centralized control stations

For systems that require frequent local manual adjustment, a suitable operator-interface solution should be considered separately.

19. Main Product Applications

Large Pumping Systems

The drive is particularly suitable for large pumping systems.

Potential applications include:

• Water-treatment plants
• Wastewater systems
• Cooling-water systems
• Industrial circulation pumps
• Process pumps
• Irrigation systems
• Mining water systems
• Chemical-process pumps

Variable-speed operation allows the pump motor to operate according to actual process demand.

This can improve process control and may reduce unnecessary energy consumption.

Large Industrial Fans

Large fans are another natural application for a 710 A-class PowerFlex 755 drive.

Typical applications include:

• Furnace fans
• Industrial ventilation
• Cooling towers
• Process-air systems
• Exhaust systems
• Dust-collection systems
• Combustion-air systems
• Mine ventilation

Fan speed can be adjusted according to airflow demand instead of continuously operating at maximum speed.

Large Conveyors

Large conveyors can benefit significantly from controlled motor acceleration and deceleration.

Typical applications include:

• Mining conveyors
• Cement conveyors
• Aggregate conveyors
• Bulk-material handling
• Port facilities
• Steel plants
• Ore handling
• Material-processing plants

Controlled acceleration can reduce mechanical shock to belts, gearboxes, couplings, and other mechanical components.

Mining

Mining is one of the most demanding environments for large motor-control equipment.

Potential applications include:

• Ore conveyors
• Crushers
• Mine ventilation
• Large pumps
• Material handling
• Processing equipment
• Auxiliary machinery

The high current capability of the PowerFlex 755 platform makes it suitable for large mining motors when the actual duty cycle and environmental conditions are within the applicable requirements.

Cement and Aggregate

Large cement plants can have many high-power motors.

Potential applications include:

• Crushers
• Fans
• Conveyors
• Pumps
• Feeders
• Material handling
• Process equipment

The drive’s large power capacity can support these high-energy mechanical processes.

Steel and Metal Processing

The drive can also be applied to large motors used in metal-processing systems.

Typical applications may include:

• Cooling fans
• Process pumps
• Large conveyors
• Auxiliary machinery
• Material-handling systems
• Production equipment

The network capability can be useful when the drive is integrated into a centralized production-control system.

Compressors

Large compressors often require substantial motor power and controlled acceleration.

The PowerFlex 755 platform can be considered for appropriate compressor applications where the motor characteristics and compressor operating requirements are compatible with the drive.

Particular attention should be given to starting torque, acceleration time, operating speed, load inertia, and process requirements.

20. Product Advantages

High 710 A Current Capacity

The most significant feature of the 20G11TD710AN0NNNNN is its 710 A current rating.

This provides a very high current capacity for large industrial motors.

It is therefore suitable for applications well beyond the practical range of small and medium compact VFDs.

650 HP Light-Duty Capability

The 650 HP Light-Duty rating provides a large amount of motor capacity for applications with moderate overload requirements.

Large centrifugal fans and pumps can be particularly suitable for this duty class.

600 HP Normal-Duty Capability

The 600 HP Normal-Duty rating makes this model suitable for many large continuous industrial processes.

It provides a useful selection reference for high-power pumps, fans, conveyors, compressors, and processing equipment.

450 HP Heavy-Duty Capability

The 450 HP Heavy-Duty rating allows the drive to address more demanding mechanical loads.

This is particularly important for machinery with higher starting torque or more severe cyclic operation.

Industrial Ethernet/IP

Embedded Ethernet/IP makes it easier to integrate the drive into modern industrial control architectures.

This can be particularly valuable in plants with centralized PLC and HMI systems.

Flexible Industrial Platform

The PowerFlex 755 platform is designed to support sophisticated industrial motor-control requirements.

It is suitable when the drive needs to work as part of a larger automation system rather than simply functioning as a standalone speed controller.

Large-Motor Capability

The combination of high current and high horsepower makes this model suitable for large motors that require substantial electrical capacity.

Multiple Duty Classes

The Light-Duty, Normal-Duty, and Heavy-Duty ratings allow the drive to be matched to different machine characteristics.

This is important because a motor’s horsepower rating alone does not fully describe the electrical requirements of the application.

A typical system can be structured as:

Incoming Power → Protection → PowerFlex 755 → Motor → Mechanical Load

The control side can be structured as:

PLC → Ethernet/IP → PowerFlex 755

An operator interface can then be added:

HMI → Industrial Network → PLC / Drive

This architecture allows the drive to participate in machine-level and plant-level control.

24. Advantages for Large Production Plants

Large production facilities often have hundreds of motors distributed throughout the plant.

For high-power motors, the drive becomes an important part of the production infrastructure.

The ability to communicate with the plant automation system can provide advantages in:

• Centralized monitoring
• Alarm management
• Fault diagnostics
• Speed control
• Process control
• Production optimization
• Maintenance planning
• Operating-status monitoring

These models provide a useful high-power selection range.

The 20G11TD485AN0NNNNN and 20G11TD545AN0NNNNN are appropriate when the required current is lower.

The 20G11TD617AN0NNNNN sits below the target model.

The 20G11TD740AN0NNNNN provides additional current and horsepower capacity above the target model.

26. Same-Series Model Comparison with Approximate Dimensions and Weight

The dimensions and weight in this table are intended as approximate product-planning values for the large Frame 8 configuration.

The exact final dimensions should be checked against the particular mechanical arrangement before cabinet fabrication or equipment-room planning.

27. Five Recommended Related PowerFlex 755 Models

Model	Voltage	Current	LD Rating	ND Rating	HD Rating	Frame	Main Application
20G11TD430AN0NNNNN	480 VAC	430 A class	400 HP	350 HP	300 HP	8	Medium-large industrial motors
20G11TD485AN0NNNNN	480 VAC	485 A class	450 HP	400 HP	350 HP	8	Pumps, fans, conveyors

This group is useful when comparing different current capacities within the same PowerFlex 755 high-power family.

28. Higher-Capacity Alternative

The 20G11TD740AN0NNNNN is one of the most logical higher-capacity alternatives to the target model.

Parameter	20G11TD710AN0NNNNN	20G11TD740AN0NNNNN
Voltage	480 VAC	480 VAC
Current	710 A	740 A
Light Duty	650 HP	700 HP
Normal Duty	600 HP	650 HP
Heavy Duty	450 HP	500 HP

Application	Large Industrial Motors	Very Large Industrial Motors

If a project requires additional current margin or a higher horsepower classification, the 740 A version can be considered.

However, selecting a larger drive simply to obtain more horsepower is not always necessary. The actual motor current and duty cycle should remain the primary selection criteria.

29. Five Popular Allen-Bradley Models from Other Drive Families

The following five models provide useful comparisons across the broader Allen-Bradley variable-frequency drive range.

They are not direct replacements for the 710 A PowerFlex 755. They are more appropriate for lower-power or different industrial applications.

Model	Series	Voltage Class	Current Class	Phase	General Power Class	Typical Application
25B-D024N114	PowerFlex 525	480 VAC	24 A class	3 PH	Small / Medium	Pumps, fans, conveyors
25B-D6P0N114	PowerFlex 525	480 VAC	6 A class	3 PH	Small	Small machinery
20F11NC3P4JA0NNNNN	PowerFlex 753	480 VAC	Small current class	3 PH	Small / Medium	Industrial automation
20F11ND077AA0NNNNN	PowerFlex 753	480 VAC	77 A class	3 PH	Medium / Large	Industrial machinery
25C-D043N114	PowerFlex 523	480 VAC	43 A class	3 PH	Medium	General-purpose machinery

The PowerFlex 523 and 525 families are generally more appropriate for compact machinery and lower-power motors.

The PowerFlex 753 family provides a more advanced industrial platform for medium and larger applications.

The PowerFlex 755 family, including the 20G11TD710AN0NNNNN, is intended for substantially larger industrial motor applications.

30. Comparison of Allen-Bradley Drive Families

Large conveyor	PowerFlex 755	20G11TD710AN0NNNNN
Very large motor	PowerFlex 755	20G11TD740AN0NNNNN

32. Installation Considerations

Electrical Room Planning

Because this is a large Frame 8 drive, sufficient electrical-room space must be provided.

The installation should consider:

• Drive dimensions
• Cable-bending space
• Ventilation
• Service access
• Front access
• Power-distribution equipment
• Grounding
• Cabinet or enclosure arrangement
• Lifting access

Mechanical Support

A drive weighing approximately 335 kg requires suitable mechanical support.

The supporting structure should be designed for the equipment weight and installation environment.

The equipment should not be treated like a small wall-mounted inverter.

Lifting and Handling

During transportation and installation, suitable lifting and handling equipment should be used.

Large Frame 8 equipment may require specialized handling arrangements.

The route from unloading area to final installation position should be planned before delivery.

Ventilation

The forced-air cooling system requires a suitable airflow path.

The cabinet should not trap hot air around the drive.

Airflow should be designed so that hot exhaust air does not return directly to the cooling intake.

33. Power Cable Considerations

At a rated current of 710 A, power-cable selection becomes a major part of the system design.

The final cable arrangement depends on:

• Installation method
• Conductor material
• Cable temperature rating
• Ambient temperature
• Cable grouping
• Cable length
• Voltage drop
• Short-circuit conditions
• Applicable electrical regulations
• Terminal arrangement

The motor cable should also be selected with consideration for variable-frequency-drive operation rather than treating it as an ordinary fixed-frequency motor installation.

34. Grounding and EMC Considerations

High-power variable-frequency drives can generate common-mode currents and high-frequency electrical noise.

Grounding and cable-routing practices should therefore be planned carefully.

Important considerations include:

• Protective grounding
• Motor-frame grounding
• Cable shielding where appropriate
• Control-cable separation
• Power-cable routing
• Cabinet bonding
• EMC requirements
• Motor-cable length

The exact grounding and EMC arrangement should follow the requirements of the specific drive and installation.

35. Maintenance Recommendations

Maintenance Item	Recommended Attention
Model	20G11TD710AN0NNNNN
Cooling Fans	Inspect airflow, noise and condition
Air Passages	Keep clean and unobstructed
Cabinet Ventilation	Check regularly
Filters	Inspect and clean as required
Power Connections	Inspect for overheating and looseness
Grounding	Check grounding integrity
Ethernet/IP	Check communication stability
Fault History	Review alarms and trips
Motor	Check motor operating condition
Motor Cables	Inspect insulation and terminals
Cabinet Temperature	Monitor operating conditions
Spare Parts	Maintain critical spares

Because this is a high-power drive, preventive maintenance can be especially important.

A failure of a large production drive can stop an entire process line, so cooling-system inspection, electrical-connection inspection, and fault-history monitoring can be valuable parts of a maintenance program.

36. Advantages in Continuous-Process Applications

The 20G11TD710AN0NNNNN is particularly useful in continuous-process environments.

Examples include:

• Water-treatment facilities
• Mining operations
• Cement production
• Steel production
• Chemical processing
• Large manufacturing plants
• Material-handling facilities

In these environments, motor speed often needs to change according to process demand.

Variable-speed control can therefore provide advantages in:

• Process regulation
• Flow control
• Pressure control
• Airflow control
• Material movement
• Mechanical acceleration
• Energy management

37. Advantages in Energy Management

Large motors consume substantial amounts of electrical energy.

When a process does not require full motor speed at all times, variable-speed operation can allow the motor to operate closer to the actual process requirement.

This can be especially useful in centrifugal fan and pump applications.

The energy-saving potential depends heavily on the mechanical load, process operating point, motor efficiency, system design, and operating schedule.

38. Advantages in Mechanical Protection

Controlled acceleration and deceleration can reduce mechanical shock.

For large equipment, sudden starting can place significant stress on:

• Gearboxes
• Couplings
• Belts
• Shafts
• Bearings
• Conveyor structures
• Pump systems
• Fan assemblies

Variable-speed control allows acceleration and deceleration to be managed according to the mechanical system.

39. Advantages in Process Control

The drive can also improve process flexibility.

For example, a large pump can be operated at different speeds according to flow demand.

A large fan can adjust speed according to airflow demand.

A conveyor can operate at different speeds according to production requirements.

This allows the motor-control system to become part of the process-control strategy rather than simply acting as an on/off motor starter.

40. Lifecycle Consideration

The 20G11TD710AN0NNNNN is an older AN configuration of the PowerFlex 755 air-cooled drive family.

For current replacement planning, the closely related 20G11TD710JN0NNNNN is the direct replacement configuration.

The main electrical rating remains in the same high-power class:

Parameter	20G11TD710AN0NNNNN	20G11TD710JN0NNNNN
Voltage	480 VAC	480 VAC
Current	710 A	710 A
Light Duty	650 HP	650 HP
Normal Duty	600 HP	600 HP
Heavy Duty	450 HP	450 HP
Frame	8	8
Cooling	Forced Air	Forced Air
Filtering	Filtered	Filtered
CM Jumper	Removed	Installed
Dynamic Braking	None	None
HIM	Blank / No HIM	Blank / No HIM
Product Family	PowerFlex 755	PowerFlex 755

The most important difference in this comparison is the CM jumper configuration.

For retrofit applications, the replacement should therefore be evaluated as a complete electrical configuration rather than simply matching the 710 A current rating.

41. Why the 20G11TD710AN0NNNNN Is a High-End Industrial Drive

The drive combines several characteristics that make it particularly suitable for high-power applications:

• 710 A current capacity
• 650 HP Light-Duty capability
• 600 HP Normal-Duty capability
• 450 HP Heavy-Duty capability
• 480 VAC three-phase operation
• Frame 8 construction
• Forced-air cooling
• Embedded Ethernet/IP
• AC input with precharge
• DC terminals
• Filtered configuration
• Industrial PowerFlex 755 architecture

Together, these characteristics make the model appropriate for large-scale motor-control systems where electrical power, process requirements, and automation integration all need to be considered.

45. Overall Product Evaluation

The Allen-Bradley 20G11TD710AN0NNNNN is a large-capacity PowerFlex 755 AC drive intended for serious industrial motor-control applications.

Its 710 A rating, 650 HP Light-Duty capacity, 600 HP Normal-Duty capacity, and 450 HP Heavy-Duty capacity give it substantial flexibility across different industrial load profiles.

The drive is particularly suitable for large pumps, industrial fans, conveyors, compressors, mining equipment, cement machinery, steel-processing equipment, water-treatment systems, and other large motor-driven processes.

Its embedded Ethernet/IP communication makes it particularly valuable in automated plants where drive operation needs to be coordinated with PLCs, HMIs, SCADA systems, and other networked equipment.

The Frame 8 construction provides the electrical and physical capacity needed for high-power operation, but it also means that the installation must be planned carefully. Cabinet space, ventilation, cable routing, grounding, lifting, mechanical support, maintenance access, and heat dissipation are all important considerations.

The approximately 720 × 2185 × 650 mm physical reference size and approximately 335 kg weight also make it clear that this is large industrial equipment rather than a compact VFD.

Another important point is the catalog configuration. The AN version uses a removed CM jumper, while the related JN configuration uses the CM jumper installed. This distinction should be considered carefully when replacing an existing drive or designing a retrofit.

For an existing installation, the original 20G11TD710AN0NNNNN catalog number remains important for identifying the installed equipment.

For a new installation or replacement project, the 20G11TD710JN0NNNNN should be evaluated as the current direct replacement configuration.

Overall, the 20G11TD710AN0NNNNN can be regarded as a high-power, industrial-networked, Frame 8 PowerFlex 755 AC drive designed for large motors and demanding production equipment. Its combination of high current capacity, multiple duty ratings, industrial communication, forced-air cooling, and large-motor capability makes it a strong choice for heavy industrial motor-control applications where reliability, controllability, and system integration are important.
