3. Product Description

The 20G11LE760AN0NNNNN is intended to control large three-phase AC motors by regulating the frequency and voltage supplied to the motor.

Instead of operating a motor continuously at full speed, the drive allows the motor’s operating speed and torque to be adjusted according to the actual requirements of the machine.

For large pumps, fans, compressors, conveyors, mixers, crushers and other heavy industrial equipment, this type of control can provide considerably more flexibility than direct-on-line motor starting.

The 760 A current rating places this model in the high-capacity range of industrial AC drives. The model is therefore not primarily intended for small machines or compact control panels. It is better suited to large industrial systems where substantial motor power is required.

The PowerFlex 755 architecture also allows the drive to be integrated into a larger automation system. Embedded EtherNet/IP provides a practical connection to an industrial control network, allowing operating data, commands, alarms and drive status to be exchanged with the supervisory control system.

---

6. Product Series – PowerFlex 755

The PowerFlex 755 is part of the PowerFlex 750-Series family of industrial AC drives.

The series is designed for applications requiring more than simple motor starting and stopping. It is intended for systems where speed control, torque control, feedback, network communication, machine integration and flexible configuration are important.

A major characteristic of the PowerFlex 755 family is its modular architecture.

Depending on the application, the drive can be configured with different feedback, communication, I/O and control options.

This makes the series appropriate for many different types of industrial machinery.

The 20G11LE760AN0NNNNN represents the high-power end of this product concept, with a 760 A output rating and very high motor-power capability.

---

7. Main Product Functions

7.1 Variable Speed Control

The primary function of the drive is to control the speed of an AC motor.

Instead of supplying the motor with a fixed-frequency power supply continuously, the drive modifies the electrical output according to the required operating speed.

This is particularly valuable in applications where the machine does not need to operate at full speed all the time.

For example, a pump may require only 60% of its maximum operating speed during part of the production process. A properly selected variable frequency drive can reduce the motor operating speed accordingly.

---

7.2 Motor Torque Control

The PowerFlex 755 platform can be used for applications requiring substantial torque control.

This is important for conveyors, hoists, processing machinery, mixers, crushers and other equipment where maintaining motor torque is important to the production process.

The 760 A capacity gives this particular model the electrical capability to support very large motors.

---

7.3 Controlled Acceleration and Deceleration

The drive can provide controlled motor acceleration and deceleration instead of allowing the motor to start or stop abruptly.

This can reduce mechanical stress on:

• Motor shafts
• Gearboxes
• Couplings
• Conveyor belts
• Pumps
• Fans
• Machine structures

Controlled acceleration can also help reduce the electrical and mechanical impact associated with large motor starting.

---

7.4 Industrial Network Integration

---

8.7 Material Handling

High-power material-handling equipment may require controlled speed and torque.

Examples include:

• Bulk handling systems
• Ship loading systems
• Industrial lifting machinery
• Large conveyor systems
• Processing lines

---

9. Major Product Advantages

9.1 Very High Power Capability

The biggest advantage of the 20G11LE760AN0NNNNN is its high electrical capacity.

With a 760 A output rating and a maximum listed Light Duty rating of approximately 900 HP, it is designed for very large industrial motors.

This allows one drive platform to handle applications that would be outside the practical range of smaller drives.

---

9.2 Flexible Motor Control

The PowerFlex 755 platform is designed for applications requiring more sophisticated motor control than simple speed adjustment.

This makes it suitable for machinery where speed, torque and process performance need to be coordinated.

---

9.3 Embedded EtherNet/IP

The embedded EtherNet/IP interface is an important advantage for automated production environments.

It reduces the need for a separate communication interface for many common industrial network applications.

The drive can therefore become part of a larger automation architecture.

---

9.4 Modular Architecture

The PowerFlex 755 family uses a modular approach.

This allows different applications to use different combinations of control, feedback and communication functions.

For large industrial installations, this flexibility can simplify the standardization of drive technology across multiple machines.

---

9.5 Suitable for Large Industrial Systems

The 800 mm deep MCC-style configuration makes the model particularly suitable for industrial electrical rooms and large motor-control installations.

It is not designed as a compact consumer-style inverter.

Instead, it is intended to become part of a structured industrial electrical system.

---

9.6 Controlled Starting and Stopping

Large motors can create significant mechanical stress when started directly.

Using a variable frequency drive allows acceleration and deceleration profiles to be controlled.

This can help improve machine operation and reduce unnecessary mechanical shock.

---

9.7 Potential Energy Savings

For variable-torque applications such as pumps and fans, reducing motor speed can significantly reduce power demand compared with continuously operating the motor at full speed.

The actual energy savings depend on:

• Motor efficiency
• Load profile
• Operating hours
• Required flow
• Required pressure
• System design
• Control strategy

Therefore, energy savings should be calculated according to the actual application rather than assumed solely from the drive model.

13. Selection Guide

Selecting between these models should not be based only on horsepower.

The most important parameters are:

1. Motor nameplate voltage
2. Motor full-load current
3. Required overload capacity
4. Normal Duty or Heavy Duty operating conditions
5. Starting torque requirement
6. Required acceleration and deceleration time
7. Environmental conditions
8. Enclosure requirements
9. Cooling requirements
10. Communication requirements
11. Feedback requirements
12. Dynamic braking requirements
13. Available electrical supply
14. Short-circuit protection requirements
15. Cabinet and installation dimensions

For a 760 A drive, the actual motor current should always be checked against the drive’s applicable duty rating.

A motor’s horsepower alone is not sufficient for final drive selection.

---

14. Why the 20G11LE760AN0NNNNN Is Suitable for Heavy Industrial Applications

The combination of 600 VAC, 760 A, Frame 9, high horsepower capability and PowerFlex 755 architecture makes this model particularly suitable for large industrial motor systems.

It provides a solution where the motor needs more than basic start/stop control.

For example, a large conveyor may need to start smoothly, accelerate gradually, maintain a controlled operating speed and communicate operating conditions to the plant control system.

A large pump may need its speed adjusted according to process demand.

A large fan may need variable airflow control.

A crusher may need high torque during heavy loading.

A large process machine may need the motor speed to follow a production recipe.

These are the types of applications where a high-power PowerFlex 755 drive becomes particularly valuable.

---

15. Advantages for System Integrators

For system integrators, one of the main advantages of using a PowerFlex 755 platform is the ability to standardize drive technology across different machine sizes.

A plant can use smaller models for low-power motors and larger models such as the 20G11LE760AN0NNNNN for major equipment while maintaining a consistent drive-family concept.

This can simplify:

• Engineering
• Operator training
• Maintenance
• Spare-parts planning
• Network integration
• Troubleshooting
• Control-system development

The embedded industrial communication capability is also useful when the drive needs to become part of a larger automation system.

---

16. Advantages for Maintenance

A large industrial drive represents a significant investment, so maintainability is an important consideration.

The PowerFlex 755 platform is designed around a modular industrial architecture.

Depending on configuration, different components and option modules can be handled separately rather than treating the entire drive system as a single indivisible component.

For maintenance departments, this can help with:

• Troubleshooting
• Drive diagnostics
• Fault identification
• Replacement planning
• Spare-parts management
• Preventive maintenance
• System modernization

For a 760 A installation, however, maintenance work must be performed by appropriately qualified personnel because the drive operates at high electrical power levels.

---

17. Practical Application Example

Consider a large industrial water pump driven by an approximately 700–800 HP motor.

If the pump is operated directly at full speed, the motor can consume substantial electrical power even when the process does not require maximum flow.

With a properly engineered variable frequency drive system, the motor speed can be adjusted according to process demand.

The 20G11LE760AN0NNNNN can provide the necessary current capacity for a motor in this high-power range while allowing the control system to regulate operating conditions.

The result can be improved process control and, depending on the pump/system characteristics, lower energy consumption during reduced-load operation.

---

18. Installation Considerations

Because this is a large industrial drive, installation should be planned carefully.

The electrical installation should consider:

• Input voltage
• Input current
• Short-circuit rating
• Upstream protection
• Grounding
• Cable size
• Motor cable length
• EMC requirements
• Heat dissipation
• Cabinet ventilation
• Ambient temperature
• Altitude
• Motor insulation
• Control wiring
• Network wiring

Mechanical installation should consider the large enclosure dimensions.

The 800 mm depth is especially important when planning the electrical-room layout.

Adequate clearance should also be provided for ventilation, inspection and maintenance.
