4. Product Description

The 20G11LF710AN0NNNNN is designed to regulate the speed and operating characteristics of large AC motors.

Instead of connecting a large motor directly to a fixed-frequency power supply and allowing it to operate at essentially one normal speed, a variable frequency drive controls the electrical frequency and voltage delivered to the motor.

This allows the motor to operate at different speeds according to the requirements of the machine or process.

The drive can therefore be used to control:

• Motor starting
• Motor acceleration
• Motor operating speed
• Motor deceleration
• Process speed
• Pump flow
• Fan airflow
• Conveyor speed
• Machine production rate
• Motor operating status

The high current capability of 710 A makes this model suitable for large industrial motors that are outside the practical range of compact or medium-sized variable frequency drives.

5. 690 VAC Electrical System

The model is designed for a 690 VAC three-phase power system.

This voltage class is commonly associated with large industrial motor installations.

When motor power becomes very large, a higher motor voltage can help keep current at a manageable level.

For example, large pumps, fans and conveyors can require several hundred kilowatts of motor power. A 690 VAC motor system provides an appropriate electrical architecture for many of these applications.

The 690 VAC rating is therefore one of the most important characteristics of this model.

6. 710 A Output Current

The 710 A output current rating is a major feature of the drive.

This rating allows the unit to handle substantially larger motors than smaller variable frequency drives.

The actual motor selection should always be based on the motor nameplate current, duty requirements and operating conditions rather than simply comparing motor horsepower or kilowatts.

The drive is particularly attractive for applications involving:

• Large centrifugal pumps
• Large fans
• Industrial blowers
• Large conveyors
• Mining equipment
• Crushers
• Heavy material handling
• Large process machinery
• Water-treatment equipment
• Cement machinery

7. Power Ratings

The model has three major duty ratings.

Duty	Power Rating
Light Duty	800 kW
Normal Duty	710 kW
Heavy Duty	590 kW

These ratings are important because the same motor-drive combination can experience very different electrical stresses depending on the application.

A centrifugal fan generally has a different overload profile from a crusher.

A pump generally has different starting and torque requirements from a loaded conveyor.

A crusher or high-inertia machine can impose much more demanding conditions on the drive.

Therefore, the appropriate duty rating should be selected based on the actual load.

8. Light-Duty Rating — 800 kW

The approximately 800 kW light-duty rating makes this model particularly attractive for large applications where the motor load is relatively smooth and overload requirements are moderate.

Typical examples include:

• Large centrifugal pumps
• Large cooling fans
• Industrial ventilation systems
• Large blowers
• Air-handling systems
• Water circulation systems
• Process ventilation equipment

These applications can benefit from variable-speed operation because the process does not necessarily require maximum motor speed all the time.

9. Normal-Duty Rating — 710 kW

The approximately 710 kW normal-duty rating is suitable for general industrial variable-speed applications.

Potential applications include:

• Large conveyors
• Industrial pumps
• Fans
• Blowers
• Material-handling systems
• Process machinery
• Large rotating equipment

For final selection, the motor full-load current and overload characteristics should be compared directly with the applicable drive rating.

10. Heavy-Duty Rating — 590 kW

The approximately 590 kW heavy-duty rating provides a substantial capacity for demanding motor applications.

Potential applications include:

• Crushers
• Heavy conveyors
• High-inertia machines
• Mining machinery
• Heavy process equipment
• Material-handling machinery
• Large mixers

The heavy-duty rating is particularly important when a machine requires significant starting torque or experiences frequent load changes.

11. Cooling System

The drive uses an air-cooled design.

At this power level, thermal management is a major part of system design.

The drive generates heat through the operation of its power electronics, including:

• Input power components
• DC-link components
• Inverter power devices
• Switching components
• Internal control electronics

The installation therefore needs appropriate ventilation and airflow.

Important considerations include:

• Air inlet location
• Air outlet location
• Cabinet ventilation
• Ambient temperature
• Cooling fan condition
• Dust accumulation
• Airflow obstruction
• Maintenance access

12. Mechanical Configuration

The model is associated with an 800 mm deep MCC-style configuration.

This is an important installation parameter.

Mechanical Parameter	Specification
Frame	Frame 9
Mechanical Style	800 mm Deep MCC Style
Depth	800 mm
Width	Configuration-dependent
Height	Configuration-dependent
Enclosure	Type 1 / IP20
Cooling	Air Cooled
Mounting	MCC / Cabinet Installation
Overall Dimensions	Configuration-dependent
Weight (kg)	Configuration-dependent

The 800 mm depth should be considered during preliminary cabinet and MCC planning.

The exact height and width should be checked against the mechanical configuration of the actual unit before final cabinet fabrication.

13. Dimensions

The model number establishes the general mechanical configuration, including the 800 mm deep MCC-style arrangement, but the complete physical envelope should not be estimated solely from the catalog number.

The final dimensions can depend on:

• Drive configuration
• Power section arrangement
• Cabinet arrangement
• Option configuration
• Mechanical assembly
• Connection arrangement
• Installation architecture

For this reason, the dimensions are best presented as follows:

Dimension	Value
Depth	800 mm
Width	Configuration-dependent
Height	Configuration-dependent
Overall Size	Configuration-dependent
Installation Depth	800 mm class
Weight (kg)	Configuration-dependent

For an engineering drawing, panel layout or lifting calculation, the final configured assembly dimensions should always be used.

14. Weight

The Weight (kg) of a large packaged drive should be treated as a configuration-specific mechanical parameter.

The catalog number identifies the electrical and option configuration, but the final physical assembly can vary according to mechanical arrangement.

Therefore:

Weight Item	Specification
Drive Weight	Configuration-dependent
Cabinet Weight	Configuration-dependent
Packaged Assembly Weight	Configuration-dependent
Shipping Weight	Configuration-dependent
Weight (kg)	Confirm against the final supplied assembly
Lifting Requirement	Based on actual assembly weight
Floor Loading	Must be evaluated

A small numerical value should not be assumed for a complete 710 A high-power MCC-style assembly.

For transportation, structural design and lifting calculations, the final equipment documentation should be used.

15. Embedded EtherNet/IP Communication

The drive incorporates embedded EtherNet/IP communication.

This allows it to communicate with a modern industrial automation system without requiring the same level of external communication hardware that would be needed for a completely standalone drive.

Typical information exchanged with a control system may include:

Data	Typical Function
Start Command	Starts motor
Stop Command	Stops motor
Speed Reference	Controls operating speed
Actual Speed	Monitors motor speed
Output Frequency	Monitors drive frequency
Output Current	Monitors motor loading
Drive Status	Indicates operating state
Warning	Reports abnormal conditions
Fault	Reports drive fault
Fault Reset	Resets applicable faults
Diagnostic Information	Supports troubleshooting

16. AC Input With Precharge

The configuration uses AC input with precharge.

The precharge function is important in high-power electrical equipment because it helps control the initial charging behavior of the DC-link system.

This is especially important when dealing with large power-electronic systems.

The input architecture is therefore suitable for high-power industrial installations where controlled energization of the drive’s internal DC system is required.

17. EMC Filtering

The model configuration includes filtering.

Filtering is useful for managing electromagnetic interference associated with power-electronic equipment.

This can be important in industrial plants containing:

• PLCs
• Sensors
• Instrumentation
• Industrial networks
• Control panels
• Measurement equipment
• Communication equipment

Correct grounding and cable installation remain essential even when filtering is provided.

18. CM Jumper Removed

The model configuration specifies the CM jumper removed arrangement.

This is relevant to the drive’s common-mode and grounding configuration.

The final grounding arrangement should be matched to the electrical system, motor insulation requirements, cable characteristics and site installation standards.

19. No HIM Configuration

The catalog configuration specifies a blank / no HIM arrangement.

This means the particular catalog configuration does not include a standard local human-interface module.

For automated systems, this can be convenient because the drive can be controlled and monitored through the plant control architecture.

Typical control methods may include:

• PLC control
• HMI control
• SCADA monitoring
• EtherNet/IP
• Remote start/stop
• Remote speed reference

20. Enclosure

The model is associated with a Type 1 / IP20 enclosure configuration.

This type of protection is generally intended for suitable indoor industrial installations.

The installation environment should be evaluated for:

• Dust
• Moisture
• Condensation
• Oil mist
• Corrosive substances
• Conductive contamination
• Excessive temperature
• Restricted ventilation

Where the surrounding environment is harsh, additional enclosure or environmental protection may be required as part of the overall system design.

22.7 Industrial Network Integration

Embedded EtherNet/IP provides convenient integration with industrial control systems.

This is particularly useful when the drive is part of a larger automated plant.

22.8 Large-Scale Industrial Applications

The combination of high voltage, high current and high power makes this model suitable for applications that require substantially more capacity than compact variable frequency drives.

23. Potential Energy-Saving Benefits

Variable-speed control can reduce energy consumption in applications where the motor does not need to operate continuously at full speed.

This is particularly relevant to centrifugal pumps and fans.

Instead of using a motor at full speed and controlling the process through mechanical restriction, the drive can adjust motor speed more directly.

Potential benefits include:

• Reduced throttling losses
• Better flow control

51. Final Assessment

The 20G11LF710AN0NNNNN is a high-capacity PowerFlex 755 variable frequency drive intended for large industrial motor applications.

Its 710 A output current, 690 VAC voltage class, and approximately 800 kW light-duty, 710 kW normal-duty and 590 kW heavy-duty ratings make it suitable for large machines where conventional compact drives are not sufficient.

The model is especially suitable for large pumps, fans, blowers, conveyors, mining equipment, water-treatment systems, cement machinery, aggregate-processing equipment and other high-power process machinery.

The air-cooled architecture provides a practical approach to thermal management, although proper ventilation is essential. At this power level, cabinet airflow, ambient temperature, dust control and maintenance access should all be considered during system design.

The 800 mm deep MCC-style configuration is another important mechanical characteristic. The 800 mm depth should be incorporated into preliminary cabinet and electrical-room planning, while the final height and width should be verified against the actual mechanical arrangement.

The embedded EtherNet/IP capability is useful for automated industrial facilities. It allows the drive to exchange operating information with the control system and supports remote control, monitoring, fault handling and process coordination.

Compared with the 590 A and 650 A versions, the 710 A model provides greater current capacity. The 765 A and 795 A versions can be considered when still higher current capability is required.

The most important point in selecting the drive is to compare the motor’s actual full-load current and application duty with the appropriate drive rating. A motor’s kW rating alone is not sufficient for final drive selection, especially for crushers, conveyors, mixers and other high-torque or high-inertia machines.

For mechanical planning, the key confirmed preliminary dimension is 800 mm depth. The complete width, height and Weight (kg) should be treated as configuration-dependent and verified from the final equipment configuration before manufacturing a cabinet, designing lifting equipment or calculating floor loading.

Overall, the 20G11LF710AN0NNNNN is best suited to large industrial installations requiring high-power variable-speed motor control, 690 VAC operation, substantial current capacity, industrial networking and integration with automated plant control systems.
