1. Product Overview

The 20G11BD1K4AN0NNNNN is a high-power PowerFlex 755 AC drive designed for large industrial motor-control applications.

It is part of the PowerFlex 750-Series, specifically the PowerFlex 755 product family. This configuration is an air-cooled, packaged industrial drive intended for high-power three-phase AC motors.

The model is configured for a 480 VAC, three-phase power system and has a current rating of approximately 1,420 A. Its published duty ratings are approximately 1,350 HP for Light Duty, 1,250 HP for Normal Duty, and 1,000 HP for Heavy Duty.

The configuration includes embedded EtherNet/IP, air cooling, an EMC filter, AC input with precharge, DC terminals, a Type 1/IP20-style 600 mm deep MCC-style construction, and no dynamic braking option.

The model is therefore positioned well above the capacity of conventional compact variable-frequency drives. It is intended for large pumps, fans, conveyors, process machinery, mining equipment, material-handling systems and other applications where the motor power and mechanical load are substantial.

The model has also reached discontinued status, with the original configuration discontinued in 2024. A direct-replacement catalog configuration is associated with the newer 20G11BD1K4JN0NNNNN designation. For an existing installation, the original catalog number should therefore be compared carefully with the replacement configuration rather than treating every PowerFlex 755 with a similar horsepower rating as interchangeable.

The key electrical ratings of 1,420 A, 1,350 HP LD, 1,250 HP ND and 1,000 HP HD are consistent with the listed 480 VAC PowerFlex 755 configuration.

4. Duty Ratings Explained

The different horsepower values should not be treated as three different motors that the drive can automatically operate at the same time.

They represent different application-duty conditions.

Duty	Rating	Typical Meaning
Light Duty (LD)	1,350 HP	Applications with relatively moderate overload requirements
Normal Duty (ND)	1,250 HP	General industrial continuous-duty applications
Heavy Duty (HD)	1,000 HP	Applications requiring greater overload capability
Current	1,420 A	High-current drive configuration

The correct rating depends on the actual motor load, acceleration requirements, overload profile, ambient conditions and application.

For engineering selection, motor nameplate current is more useful than horsepower alone.

A motor rated at a particular horsepower does not necessarily draw the same current in every application. Motor efficiency, power factor, voltage, load characteristics and duty cycle all affect actual current demand.

5. Approximate Power Conversion

The horsepower ratings can be converted to approximate kilowatts using 1 HP ≈ 0.746 kW.

Duty	Horsepower	Approximate kW
Light Duty	1,350 HP	Approx. 1,007 kW
Normal Duty	1,250 HP	Approx. 933 kW
Heavy Duty	1,000 HP	Approx. 746 kW

These are mathematical conversions rather than separate electrical ratings.

For final equipment selection, the motor’s actual nameplate information should be used.

6. Product Introduction

The 20G11BD1K4AN0NNNNN is a very large industrial variable-frequency drive intended to regulate the operation of high-power AC motors.

A conventional motor starter primarily provides switching and protection functions. A variable-frequency drive goes much further.

It electronically controls the electrical power supplied to the motor so that motor speed and torque can be adjusted according to the requirements of the process.

This becomes especially valuable with large motors.

A large pump, for example, does not always need to operate at maximum speed.

A large fan may need different airflow levels throughout the day.

A conveyor may need to accelerate gradually and then operate at different speeds depending on material flow.

A process machine may need precise coordination between motor speed and other production equipment.

In each of these situations, the drive becomes an important part of the overall process-control system.

7. How the Product Fits into an Industrial System

A typical system can be represented as:

Industrial AC Supply → PowerFlex 755 Drive → AC Motor → Mechanical Load

The drive receives three-phase AC power.

It controls the electrical output delivered to the motor.

The motor converts that electrical energy into mechanical torque.

The mechanical equipment then performs the required process function.

The drive can receive speed or operating commands from an operator station, controller or industrial network.

It can also provide operating information back to the automation system.

This creates a complete motor-control loop rather than a simple motor start/stop arrangement.

8. Main Product Functions

Variable-Speed Operation

The drive can adjust motor speed according to the required process condition.

This is one of its most important functions.

A motor that normally runs at full speed can operate at a lower speed when the process does not require maximum output.

This can improve process flexibility and, in suitable applications, reduce energy consumption.

Controlled Acceleration

Large motors can have considerable inertia.

If a large motor is started abruptly, the mechanical system can experience a sudden increase in torque.

Controlled acceleration allows the motor to increase speed progressively.

This can reduce mechanical shock to:

• Shafts
• Couplings
• Gearboxes
• Conveyor belts
• Pumps
• Fans
• Bearings
• Mechanical structures

Controlled Deceleration

The same principle applies when stopping.

A controlled deceleration profile can reduce sudden mechanical loading and can help maintain a smoother process.

This is especially useful for equipment with large rotating masses.

Speed Regulation

The drive can regulate motor speed according to a reference value.

This is important for production lines where process speed must remain stable.

For example, conveyor speed can be coordinated with upstream and downstream machines.

Torque Control

The PowerFlex 755 platform is intended for applications requiring advanced motor control.

Torque control can be useful where the mechanical load changes significantly during operation.

This makes the platform appropriate for material handling, large conveyors, process machinery and other demanding equipment.

Industrial Network Communication

The configuration includes embedded EtherNet/IP.

This allows the drive to become part of an industrial automation system.

Depending on the control architecture, the system can exchange information such as:

• Start commands
• Stop commands
• Speed references
• Actual speed
• Motor current
• Drive status
• Fault status
• Alarm information
• Diagnostic information

This reduces the need to treat the drive as an isolated piece of equipment.

9. Product Applications

9.1 Mining

Mining operations commonly use extremely large electric motors.

The 20G11BD1K4AN0NNNNN is suitable for evaluating applications such as:

• Large ore conveyors
• Crushers
• Dewatering pumps
• Ventilation fans
• Material-handling systems
• Process pumps
• Heavy processing machinery

Controlled acceleration is particularly valuable on long conveyors because sudden acceleration can create high mechanical stress.

9.2 Cement Production

Large cement plants contain many high-power motors.

Possible applications include:

• Large process fans
• Crushers
• Conveyors
• Pumps
• Material-handling equipment
• Process machinery

The ability to adjust motor speed can help match equipment output to actual production requirements.

9.3 Steel and Metals Processing

Steel and metals-processing facilities can have large continuous-duty motor loads.

Potential applications include:

• Cooling systems
• Large fans
• Pumps
• Conveyors
• Material handling
• Processing machinery

The drive can also be integrated into larger control systems where multiple machines must operate together.

9.4 Water and Wastewater

Large water and wastewater facilities can require substantial pump motors.

Variable-speed control can be useful when flow requirements change throughout the operating cycle.

Applications may include:

• Raw-water pumping
• Process-water pumping
• Wastewater pumping
• Cooling-water systems
• Industrial circulation systems

9.5 Large Fans and Blowers

Fans and blowers are excellent candidates for variable-speed control when airflow requirements change.

Typical applications include:

• Furnace fans
• Combustion-air systems
• Industrial ventilation
• Process-air systems
• Exhaust systems
• Large cooling systems

9.6 Conveyor Systems

Large conveyors are commonly found in mining, ports, bulk-material handling and heavy manufacturing.

The drive can provide:

• Controlled acceleration
• Controlled deceleration
• Adjustable conveyor speed
• Process synchronization
• Motor monitoring

This can help reduce mechanical stress and improve production control.

10. Product Advantages

10.1 Very High Current Capacity

The approximately 1,420 A rating is one of the defining characteristics of this model.

This puts the drive into a very high-power class and allows it to be considered for motors that are far beyond the capacity of compact industrial drives.

It is therefore appropriate for large industrial machinery where electrical load requirements are substantial.

10.2 High Horsepower Capability

The approximate ratings of:

1,350 HP LD

1,250 HP ND

1,000 HP HD

provide a wide range of application possibilities.

This makes the drive suitable for different loading conditions within the same general high-power platform.

10.3 Controlled Motor Starting

Large motors can produce substantial starting current and mechanical stress.

A variable-frequency drive provides controlled acceleration.

This can improve the starting behavior of large machines and reduce mechanical shock.

10.4 Better Process Control

The drive makes motor speed a controllable process variable.

This allows production equipment to respond to changes in process demand.

Instead of operating a motor continuously at maximum speed, the system can adjust motor speed according to the required output.

10.5 Industrial Automation Integration

The embedded EtherNet/IP capability makes the drive suitable for automated plants.

The motor controller can communicate with the wider control system, allowing operators and maintenance personnel to obtain information without needing to work directly at the drive.

10.6 Diagnostic Information

Large industrial motors are expensive assets.

Drive diagnostics can help maintenance personnel investigate abnormal conditions.

Information related to current, speed, faults, alarms and drive status can help shorten troubleshooting time.

10.7 Air-Cooled Construction

Air cooling provides a practical solution for many industrial installations.

There is no requirement for a dedicated liquid-cooling circuit.

The trade-off is that the electrical installation must provide adequate airflow and heat removal.

11. Mechanical Dimensions and Weight

The model is a large packaged industrial drive.

The specified construction is approximately 600 mm deep and is associated with a Type 1/IP20, MCC-style configuration.

Because the complete mechanical package can vary depending on the selected enclosure and factory configuration, overall height and width should not be treated as universal values.

Mechanical Parameter	Value / Description
Model	20G11BD1K4AN0NNNNN
Depth	600 mm
Width	Configuration dependent
Height	Configuration dependent
Cooling	Forced Air
Construction	MCC Style
Enclosure	Type 1 / IP20
Installation	Floor / cabinet / MCC
Equipment Weight	Approx. 1,000 kg class
Exact Net Weight	Configuration dependent
Shipping Weight	May exceed net equipment weight
Handling	Industrial lifting equipment normally required
Ventilation	High airflow required
Service Space	Significant access area required

The 600 mm depth and Frame 9 configuration are part of the listed catalog configuration.

The weight should be treated as a planning estimate rather than a certified value. For transportation, lifting, structural calculations and foundation design, the actual configured equipment weight should be confirmed from the equipment documentation.

12. Electrical Installation Requirements

A drive with approximately 1,420 A capacity requires a carefully engineered electrical installation.

Important considerations include:

Area	Requirement
Input Voltage	480 VAC
Input Phase	Three Phase
Supply Capacity	Must support the drive load
Protection	Proper upstream protection
Grounding	Correct industrial grounding
Motor Cable	Correctly sized for motor current
Motor Insulation	Suitable for VFD operation
EMC	Appropriate installation and cable arrangement
Cooling	Adequate forced airflow
Ambient Temperature	Must remain within applicable limits
Altitude	Check applicable derating
Cabinet Space	Adequate ventilation and service clearance
Maintenance	Safe access required
Lifting	Heavy-equipment handling plan required

The original catalog configuration is listed with an EMC filter, AC input with precharge and no dynamic braking.

13. EMC and Grounding Considerations

The model is configured with an EMC filter.

This is relevant in industrial environments where electrical noise can affect sensitive equipment.

However, the filter does not remove the need for good installation practice.

Motor cables, control cables, grounding conductors and communication cables should be routed appropriately.

Grounding should be designed as part of the complete electrical system.

The drive configuration also identifies a removed common-mode capacitor jumper, which is an important configuration characteristic.

For replacement work, this configuration detail should be preserved or deliberately changed only after evaluating the electrical system.

14. Cooling and Thermal Management

Because the drive is rated for approximately 1,420 A, it produces significant heat during operation.

The air-cooling system therefore plays an important role.

The electrical room or enclosure must provide sufficient airflow.

Important considerations include:

• Ambient temperature
• Airflow direction
• Fan condition
• Air inlet cleanliness
• Exhaust-air path
• Cabinet ventilation
• Dust accumulation
• Installation altitude

A blocked airflow path can cause operating temperature to increase.

For this reason, cooling-system inspection should be part of routine maintenance.

15. Energy-Saving Potential

Variable-speed operation can provide meaningful energy savings in appropriate applications.

The most obvious examples are centrifugal pumps and fans.

When the process does not require full flow or full airflow, reducing motor speed can reduce the required mechanical power.

The actual energy-saving result depends on the application.

Important factors include:

• Motor efficiency
• Pump or fan characteristics
• Operating hours
• Required flow
• Required pressure
• Existing control method
• Speed profile
• Mechanical efficiency

The drive should therefore be considered a tool for improving process efficiency rather than an automatic guarantee of a specific energy-saving percentage.

16. Maintenance Advantages

The PowerFlex 755 platform can provide useful operating information for maintenance personnel.

For a large motor-control system, this information can help identify abnormal operating conditions before they become major failures.

Typical maintenance activities include:

• Checking cooling fans
• Cleaning ventilation paths
• Inspecting power connections
• Checking grounding
• Reviewing fault history
• Checking motor cables
• Checking communication connections
• Monitoring operating temperature
• Inspecting cabinet cleanliness
• Checking the surrounding electrical environment

24. Replacement Considerations

The original 20G11BD1K4AN0NNNNN is a discontinued configuration.

The direct-replacement designation associated with the original product is 20G11BD1K4JN0NNNNN.

This is important for customers maintaining older industrial equipment.

A replacement drive should not be selected solely according to:

• Horsepower
• Voltage
• Current

The following should also be compared:

• Complete catalog number
• Frame size
• Input configuration
• Output current
• Duty rating
• Communication configuration
• EMC configuration
• Dynamic braking
• HIM/operator interface
• Physical dimensions
• Cabinet arrangement
• Motor cable arrangement
• Control wiring
• Parameter configuration
• Existing automation architecture

The original model’s lifecycle status and direct replacement information are part of the product’s current lifecycle classification.

25. Advantages for Heavy Industrial Applications

The main value of this drive becomes clear when it is considered as part of a complete industrial process.

For a large conveyor, it can control acceleration and speed.

For a large pump, it can regulate flow by changing motor speed.

For a large fan, it can adjust airflow.

For a mining machine, it can provide controlled motor operation under demanding mechanical conditions.

For a steel-processing system, it can coordinate motor speed with the wider production process.

For water infrastructure, it can control large pump motors according to changing demand.

This flexibility is the central advantage of a high-power variable-frequency drive.

26. Why the 20G11BD1K4AN0NNNNN Is Attractive

The model is particularly attractive when several requirements exist at the same time.

The motor is very large.

The process needs variable speed.

The machine requires controlled acceleration.

The process benefits from torque control.

The plant uses centralized automation.

The maintenance team needs drive diagnostics.

The application operates for long periods.

The mechanical equipment is expensive and benefits from reduced starting shock.

When these conditions are present, a high-power PowerFlex 755 configuration can provide much more value than a basic motor starter.

27. Overall Technical Assessment

The 20G11BD1K4AN0NNNNN is a very-high-power, air-cooled PowerFlex 755 AC drive designed for large three-phase industrial motors.

Its approximately 1,420 A current rating and 1,350 HP LD / 1,250 HP ND / 1,000 HP HD ratings place it firmly in the high-power industrial category.

The combination of 480 VAC three-phase input, air cooling, 600 mm MCC-style construction, EMC filtering, AC input with precharge and embedded EtherNet/IP makes it suitable for sophisticated industrial motor-control systems.

Its strongest applications are large pumps, fans, conveyors, mining equipment, cement machinery, metals-processing equipment, water infrastructure and heavy material-handling systems.

The most important mechanical characteristic is its large physical size. The 600 mm depth is specified for this configuration, while the exact height, width and final equipment weight depend on the complete packaged arrangement.

For preliminary planning, an equipment weight of approximately 1,000 kg class can be used as a general planning figure, but this should not be used as the certified lifting or shipping weight.

The model’s lifecycle status is also important. The original 20G11BD1K4AN0NNNNN configuration was discontinued, and the associated direct-replacement configuration is 20G11BD1K4JN0NNNNN.

30. Conclusion

The 20G11BD1K4AN0NNNNN is best classified as a very-high-power industrial variable-frequency drive rather than a conventional general-purpose VFD.

With approximately 1,420 A, 1,350 HP LD, 1,250 HP ND and 1,000 HP HD capability, it is intended for large motor applications where electrical capacity, mechanical control and process integration are all important.

Its 480 VAC three-phase input, air-cooled design, 600 mm MCC-style construction, EMC filtering, AC input with precharge, embedded EtherNet/IP, and high-power Frame 9 architecture make it particularly suitable for heavy industrial environments.

The strongest application areas are large pumps, industrial fans, blowers, mining conveyors, cement equipment, steel and metals processing, water infrastructure and heavy material-handling systems.

The most important selection point is to match the drive to the actual motor current and duty cycle, not simply to the motor horsepower.

For a motor slightly below the capacity of this model, 20G11BD1K3AN0NNNNN can be considered.

For a higher-capacity application, 20G11BD1K5AN0NNNNN provides another logical comparison.

For an existing installation using the original model, 20G11BD1K4JN0NNNNN should be evaluated as the direct-replacement configuration, with all electrical, mechanical, communication and control characteristics checked before replacement.

Overall, the 20G11BD1K4AN0NNNNN is a strong choice for very large industrial motor-control systems where high current capacity, variable-speed operation, controlled acceleration, process integration and industrial diagnostics are required.
