1. Product Overview

The 20G11LE760JN0NNNNN is a high-power PowerFlex 755 AC drive designed for large industrial motor-control applications.

It is a three-phase, 600 VAC-class, air-cooled variable frequency drive with a 760 A output-current rating. Its published duty ratings are approximately 900 HP for Light Duty (LD), 800 HP for Normal Duty (ND), and 700 HP for Heavy Duty (HD).

The unit is configured as an 800 mm deep MCC-style drive, with a Frame 9 power structure, Type 1 / IP20 enclosure, forced-air cooling, AC input with DC terminals, embedded EtherNet/IP, filtered configuration, CM jumper installed, no dynamic braking and no door-mounted HIM.

The model is positioned toward the high-power end of the PowerFlex 755 range. It is intended for applications where the motor is too large for compact or general-purpose drives and where controlled speed, torque, acceleration, deceleration and industrial-network integration are required.

3. Basic Technical Parameters

Important note regarding dimensions and weight

The 800 mm dimension is the key published mechanical dimension associated with this configuration and refers to the deep MCC-style arrangement.

The complete installation can contain additional cabinet sections, wiring compartments, disconnect/protection equipment and other components. Consequently, the total assembled package cannot safely be represented by a single universal width, height or shipping-weight figure.

For procurement, transportation and cabinet-floor loading, the actual mechanical drawing and the exact configured package should always be used.

The frequently quoted 14.5 kg figure should not be interpreted as the weight of the complete 800 mm MCC-style packaged installation. It is more appropriately treated as a component-level/catalog reference and is therefore not suitable for calculating the shipping weight of the complete high-power assembly.

---

4. Product Description

The 20G11LE760JN0NNNNN is designed to control the speed and torque of large AC motors by converting incoming AC electrical power into controlled variable-frequency output power.

The basic operating concept is straightforward.

The drive receives three-phase AC power, processes that electrical power through its converter and inverter stages, and produces controlled output voltage and frequency for the connected motor.

By adjusting the output frequency and voltage, the drive can control motor speed according to the requirements of the machine.

This is particularly useful when a motor does not need to operate continuously at maximum speed.

For example, a large pump may need high flow during one part of a production process and significantly lower flow during another part. Instead of operating the motor continuously at full speed and controlling the process with mechanical restrictions, the drive can regulate motor speed more directly.

The same principle can be applied to fans, blowers, conveyors, compressors, mixers and many other large industrial machines.

---

5. What Makes the 20G11LE760JN0NNNNN a High-Power Drive?

The most important number in this model is 760 A.

A 760 A output rating places the drive firmly in the large industrial-drive category.

The associated ratings are:

The difference between LD, ND and HD ratings is important because industrial machines do not all impose the same load on the motor.

A centrifugal pump or fan may have relatively smooth variable-torque characteristics.

A conveyor, crusher or heavily loaded process machine may impose much more demanding starting and overload conditions.

Therefore, a drive should be selected according to the actual motor current and application duty rather than simply choosing a model based on horsepower.

---

6. Detailed Explanation of the Main Specifications

6.1 600 VAC, Three-Phase

The drive belongs to the 600 VAC three-phase class.

This makes it suitable for industrial electrical systems using higher-voltage three-phase motors.

Higher-voltage motor systems are common in large industrial installations because they allow high motor power to be transferred at lower current than would be required at a much lower voltage.

The exact supply arrangement must always be checked against the plant electrical system before installation.

---

6.2 760 A Output Current

The 760 A output-current rating is one of the defining characteristics of the product.

This high current capability allows the drive to control very large motors.

The actual allowable motor size depends on motor voltage, motor current, duty cycle, ambient conditions and the applicable LD/ND/HD rating.

For this reason, 760 A should be regarded as the electrical current capacity rather than as a guarantee that every 900 HP motor can be operated under every possible condition.

---

6.3 900 HP Light Duty

The Light Duty rating reaches approximately 900 HP.

Light Duty is generally associated with applications where overload requirements are less severe than heavy industrial constant-torque applications.

Large pumps and fans are typical examples where the drive’s high-power capability can be particularly useful.

---

6.4 800 HP Normal Duty

The Normal Duty rating is approximately 800 HP.

This provides a useful reference point for applications requiring substantial continuous motor power but not the most demanding overload profile.

---

6.5 700 HP Heavy Duty

The Heavy Duty rating is approximately 700 HP.

Heavy Duty operation is particularly relevant where the machine requires higher overload capability or produces demanding torque characteristics.

Examples can include heavy conveyors, crushers and certain process machines.

---

7. Power Conversion Reference

For reference:

1 HP ≈ 0.746 kW

Therefore:

These conversions are nominal mathematical equivalents. They should not be interpreted as the exact electrical input power, motor efficiency or mechanical output power of a complete system.

---

8. Enclosure and Mechanical Configuration

The model uses a Type 1 / IP20, 800 mm deep MCC-style configuration.

This is an important distinction.

This is not a small compact wall-mounted inverter intended for installation in a small machine enclosure.

Instead, it is a large industrial drive configuration intended for installation as part of a structured electrical system.

The 800 mm depth must be taken into account when designing:

• Electrical rooms
• MCC lineups
• Drive cabinets
• Service aisles
• Cable routing
• Maintenance access
• Ventilation systems
• Transportation routes

The surrounding installation should also provide adequate space for heat dissipation and maintenance access.

---

9. Cooling System

The 20G11LE760JN0NNNNN uses forced-air cooling.

At this power level, heat generation is a significant engineering consideration.

The cooling system is therefore an essential part of the drive installation.

When installing the drive, attention should be paid to:

• Ambient temperature
• Ventilation
• Airflow
• Cabinet design
• Filter condition
• Cooling-fan condition
• Dust accumulation
• Installation altitude
• Heat generated by adjacent equipment

Poor ventilation can adversely affect the operating life and reliability of high-power electronic equipment.

---

10. Embedded EtherNet/IP

One of the important features of this model is embedded EtherNet/IP.

This allows the drive to be incorporated into an industrial control network.

Typical information exchanged between the drive and the control system can include:

• Start command
• Stop command
• Speed reference
• Actual speed
• Output frequency
• Motor current
• Drive status
• Fault status
• Warning status
• Operating information
• Diagnostic information

This is especially useful in automated production lines where the drive needs to communicate continuously with the main control system.

---

11. No Door-Mounted HIM

The specified configuration is listed with a blank / no HIM arrangement.

A HIM, or Human Interface Module, is normally used for local interaction with the drive.

The absence of a door-mounted HIM does not mean that the drive cannot be controlled or configured.

Instead, operation and configuration can be handled through the industrial control system, network, engineering tools or other appropriate interfaces depending on the complete system configuration.

This configuration can be attractive when the drive is intended to be managed primarily from a centralized automation system rather than by operators standing directly in front of the drive.

---

12. CM Jumper Installed

The model is configured with the CM jumper installed.

This is associated with the drive’s common-mode capacitor configuration and is an important part of the electrical configuration.

The correct configuration depends on the grounding arrangement and the specific electrical system.

This is one reason why a high-power drive should not be treated as a simple plug-and-play component.

The installation engineer needs to verify the drive configuration against the supply grounding and system requirements.

---

13. Dynamic Braking

The specified model is configured with no dynamic braking.

Dynamic braking is normally relevant to applications where the motor must decelerate quickly or where substantial regenerative energy needs to be dissipated.

The absence of an integrated dynamic-braking configuration does not automatically make the drive unsuitable for applications involving deceleration.

It simply means that braking requirements need to be considered separately during system design.

Applications with large inertial loads, rapid stopping requirements or frequent deceleration should receive particular attention during drive selection.

---

14. Product Applications

• Motor protection
• Network monitoring

The Heavy Duty rating should be considered carefully when the conveyor experiences high starting or transient loads.

---

14.4 Crushers

Crushers can impose demanding mechanical loads on motors.

Applications involving crushing, aggregate processing and mineral handling can require significant torque and overload capability.

For such applications, the 700 HP Heavy Duty rating is often more relevant than simply considering the maximum 900 HP Light Duty number.

---

14.5 Compressors

The drive can be applied to:

• Bulk conveyors
• Transfer systems
• Heavy material handling
• Loading systems
• Processing lines
• Industrial transport equipment

---

15. Product Advantages

15.1 High Current Capacity

The 760 A rating is the most obvious advantage.

It allows the same drive platform to be used for motors that would be far beyond the capacity of compact drives.

---

15.2 High Motor Power

The 900 HP Light Duty rating makes this a high-power solution for large industrial equipment.

This provides substantial capacity for applications where motor power is a major design consideration.

---

15.3 Three Duty Ratings

The availability of LD, ND and HD ratings provides greater flexibility.

The user can select the applicable rating according to the actual mechanical load.

This is particularly useful when comparing pump/fan applications with conveyors or other constant-torque equipment.

---

15.4 Industrial Network Integration

Embedded EtherNet/IP makes the drive suitable for centralized automation architectures.

This can simplify communication between the drive and the plant control system.

---

15.5 PowerFlex 755 Platform

The PowerFlex 755 architecture provides a scalable industrial-drive platform.

This is valuable for facilities that need to use multiple drive sizes while maintaining a common control philosophy.

---

15.6 Controlled Acceleration

Large motors can generate significant mechanical stress during starting.

A variable frequency drive can provide controlled acceleration.

This can reduce sudden mechanical loading on:

• Shafts
• Couplings
• Gearboxes
• Belts
• Conveyor structures
• Pump assemblies

---

15.7 Controlled Speed

The drive allows the motor to operate at different speeds according to process requirements.

This is particularly valuable for variable-torque equipment such as pumps and fans.

---

15.8 Centralized Monitoring

When connected to an industrial network, drive information can be made available to the main automation system.

This makes it easier for operators and maintenance personnel to monitor:

• Running status
• Faults
• Warnings
• Current
• Speed
• Frequency
• Operating conditions

16. Five Recommended Models from the Same Series

The following models are closely related PowerFlex 755 models and are useful for comparison when selecting a high-power drive.

The 20G11LE760JN2NNNNN is particularly close electrically to the requested model, with the major catalog difference being the selected human-interface configuration.

The 20G11LE760JN4NNNNN is another close 760 A alternative with a different option configuration.

---

17. Recommended Alternative: 20G11LE630JN0NNNNN

The 20G11LE630JN0NNNNN is a lower-current PowerFlex 755 alternative.

Its 630 A capacity makes it appropriate when the motor current does not require the full 760 A capability.

It can be considered for:

• Large pumps
• Fans
• Conveyors
• Process equipment
• Material-handling systems

Its lower current rating may also provide a better fit when the actual motor load is substantially below the 760 A class.

---

18. Recommended Alternative: 20G11LE710JN0NNNNN

The 20G11LE710JN0NNNNN is positioned between the 630 A and 760 A classes.

It can be a useful choice where the motor current is close to, but does not exceed, the 710 A range.

This model can help avoid unnecessarily oversizing the drive while retaining the PowerFlex 755 platform.

---

19. Recommended Alternative: 20G11LE760JN2NNNNN

The 20G11LE760JN2NNNNN is particularly relevant because it maintains the same basic high-power electrical class:

• 760 A
• 900 HP LD
• 800 HP ND
• 700 HP HD
• Frame 9
• 800 mm MCC style
• Embedded EtherNet/IP

Its principal difference is the human-interface configuration.

This makes it a useful model to consider when local operator access through a more advanced HIM is required.

---

20. Recommended Alternative: 20G11LE760JN4NNNNN

The 20G11LE760JN4NNNNN is another 760 A PowerFlex 755 configuration.

It retains the same general electrical class but uses a different option configuration.

This type of model is useful when a project requires a particular factory configuration rather than simply selecting the basic 760 A drive.

---

21. Recommended Alternative: 20G11LE595JN0NNNNN

The 20G11LE595JN0NNNNN provides a lower-capacity option within the same general high-power family.

Its approximately 595 A current rating and 700 HP Light Duty capability make it suitable when the 760 A capacity is unnecessary.

This can be a practical option for reducing drive capacity while retaining the same broader PowerFlex 755 architecture.

---

22. Five Popular Models Under the Same Brand

The following products represent useful comparisons from the same brand and cover different industrial automation requirements.

The five models above are not all direct electrical substitutes for the 20G11LE760JN0NNNNN.

24. Application Selection Table

---

25. Important Advantages in Industrial Automation

The product is particularly attractive in large automated plants because it combines high motor capacity with network-based control.

For a modern production system, the drive is not simply an electrical device that turns a motor on and off.

It can become an active part of the automation architecture.

The control system can issue a speed command, monitor the actual operating condition and receive information when the drive detects a fault or warning.

This approach is particularly useful in plants containing many large motors.

---

26. Advantages for System Integrators

For system integrators, the PowerFlex 755 platform offers several practical advantages.

A common drive family can be used across different motor sizes.

This can reduce differences in:

• Engineering methods
• Programming
• Operator training
• Maintenance procedures
• Troubleshooting
• Spare-parts planning
• Network architecture

The 20G11LE760JN0NNNNN can therefore serve as the high-power member of a broader standardized drive strategy.

---

27. Advantages for Maintenance Departments

Large drives require a structured maintenance strategy.

The product’s industrial architecture makes it appropriate for facilities where preventive maintenance and diagnostics are important.

Maintenance personnel can monitor drive status and faults through the automation system and can use appropriate diagnostic procedures to identify problems.

Important maintenance areas include:

• Cooling fans
• Airflow
• Electrical connections
• DC bus condition
• Power components
• Control electronics
• Network connections
• Cabinet cleanliness
• Grounding
• Environmental conditions

Because this is a high-power electrical device, maintenance should only be performed by personnel with appropriate training and authorization.

---

28. Installation Considerations

The 20G11LE760JN0NNNNN should be treated as a major electrical installation rather than a small standalone inverter.

Before installation, the following should be evaluated:

---

29. Energy-Saving Potential

A major reason for using a variable frequency drive is the potential to reduce energy consumption in suitable applications.

This is particularly important for centrifugal pumps and fans.

If a motor is continuously operated at full speed even though the process only requires partial output, a significant amount of energy may be wasted.

Reducing motor speed can lower the energy required by the machine.

However, actual savings depend on the complete system.

Important factors include:

• Motor efficiency
• Pump or fan characteristics
• Operating hours
• Load profile
• Process requirements
• Mechanical efficiency
• Control strategy
• Required pressure or flow

Therefore, energy savings should be calculated from actual operating data.

---

30. Why the 20G11LE760JN0NNNNN Is Different from a Small Industrial Drive

A compact drive may be suitable for a 5 HP, 10 HP or 20 HP machine.

The 20G11LE760JN0NNNNN operates at a completely different scale.

Its 760 A current capacity and approximately 900 HP LD rating mean that the surrounding electrical system must also be designed for high-power operation.

This affects:

• Incoming power equipment
• Cable sizing
• Protection
• Cabinet construction
• Ventilation
• Grounding
• Motor cabling
• Maintenance procedures
• Electrical-room design

Therefore, the product should normally be evaluated as part of a complete motor-drive system rather than as an isolated component.

---

31. Recommended Model Selection Strategy

If the motor current is significantly below 760 A, a lower-rated PowerFlex 755 model may be more appropriate.

If the application is close to the 760 A limit, the 760 A model provides greater capacity.

If the application requires heavy starting torque or overload operation, the Heavy Duty rating should receive priority over the maximum Light Duty horsepower rating.

If operators need local display and keypad access, a model with an appropriate HIM configuration may be preferable.

If the drive is primarily controlled through a centralized automation system, the blank-HIM configuration can be practical.

---

32. Key Specifications at a Glance

---

33. Overall Product Evaluation

The 20G11LE760JN0NNNNN is a high-capacity industrial variable frequency drive aimed at large motor applications.

Its combination of 600 VAC, 760 A, 900 HP LD, 800 HP ND, 700 HP HD, Frame 9, forced-air cooling, Type 1/IP20 enclosure and 800 mm MCC-style construction makes it particularly suitable for major industrial equipment.

Its embedded EtherNet/IP capability also makes it a strong choice for plants where motor drives need to be integrated into an automated control network.

The product is especially appropriate for large pumps, fans, conveyors, compressors, crushers, mixers and other heavy industrial machinery.

Its greatest strengths are its high current capacity, large motor-power capability, flexible duty ratings, industrial communication capability and suitability for centralized automation.

For applications requiring a similar electrical capacity but a different operator-interface configuration, 20G11LE760JN2NNNNN and 20G11LE760JN4NNNNN are logical related models.

For applications requiring somewhat less current, 20G11LE630JN0NNNNN, 20G11LE710JN0NNNNN and 20G11LE595JN0NNNNN provide useful alternatives within the same broader drive family.

In practical terms, the 20G11LE760JN0NNNNN is best viewed as a large-frame, high-current industrial AC drive for demanding motor-control systems, rather than simply as a conventional inverter.

For final purchasing or replacement work, the most important items to verify are motor nameplate current, motor voltage, LD/ND/HD duty, enclosure configuration, exact cabinet dimensions, cooling arrangement, braking requirements, communication requirements and the complete package weight.
