Allen-Bradley 20G11BD1K2AN0NNNNN — Detailed Product Specifications, Introduction, Applications, Advantages and Related Models

1. Product Overview

The 20G11BD1K2AN0NNNNN is a high-power PowerFlex 755 air-cooled AC drive designed for large industrial motor-control applications.

It is a 480 VAC, three-phase variable frequency drive with a nominal output current of approximately 1135 A. Its duty ratings reach approximately 1100 HP in Light Duty, 1000 HP in Normal Duty, and 800 HP in Heavy Duty.

This places the model in the very-high-power category of industrial AC drives. It is intended for large motors used in demanding applications such as centrifugal pumps, process pumps, industrial fans, blowers, conveyors, mining equipment, cement machinery, material-handling systems, water systems, and other large rotating machines.

The model belongs to the PowerFlex 750-Series and more specifically to the PowerFlex 755 series.

Its configuration includes an air-cooled design, 480 VAC three-phase input, AC input with precharge, DC terminals, EMC filtering, removed CM jumper, no integrated dynamic braking, embedded EtherNet/IP, and a blank/no-HIM configuration.

Because this is a Frame 9 high-power drive, the product is substantially larger and heavier than compact industrial VFDs. Mechanical planning, electrical-room space, ventilation, floor loading, transportation, lifting, cable routing, and maintenance access should all be considered as part of the installation.

---

2. Brand and Product Series

The 1135 A current rating is the most important electrical characteristic of this particular model.

Compared with the closely related 1045 A configuration, the 20G11BD1K2AN0NNNNN provides additional current and horsepower capacity, making it appropriate when the motor load is too large for the smaller model or when additional drive capacity is desired.

---

3. Main Technical Parameter Table

The approximate power equivalents above are calculated from horsepower using the conventional relationship of approximately 0.746 kW per horsepower.

The actual drive selection should always be based on the motor’s rated current, application duty, overload requirement, and operating conditions rather than simply converting horsepower into kilowatts.

---

4. Electrical Rating

The 20G11BD1K2AN0NNNNN is designed for a 480 VAC, three-phase industrial electrical system.

Its approximately 1135 A output current gives it considerable capacity for very large AC motors.

The main duty ratings can be summarized as follows:

These ratings provide a useful way to understand the drive’s operating range.

The Light Duty rating is generally most attractive for variable-torque applications such as large centrifugal pumps and fans.

Normal Duty is useful for general industrial machinery with moderate overload requirements.

Heavy Duty is more appropriate for machinery that demands higher torque during acceleration or operation.

---

5. 1135 A Output Current

The approximately 1135 A output current is the defining feature of this model.

This is a very substantial current rating.

It places the drive above the 1045 A configuration and below larger 1365 A, 1420 A, 1525 A, and 2070 A configurations in the broader high-power range.

This makes the model useful when a motor requires more capacity than an approximately 1000 A-class drive can provide.

Typical large-motor applications include:

• Large pumps
• Large fans
• Industrial blowers
• Heavy conveyors
• Mining equipment
• Material-handling systems
• Cement machinery
• Process equipment
• Large ventilation systems
• Water infrastructure

---

6. Light Duty — 1100 HP

The 1100 HP Light Duty rating is a major advantage of the model.

At this rating, the drive is suitable for very large variable-torque applications.

Typical examples include:

• Large centrifugal pumps
• Cooling-water pumps
• Large process fans
• Industrial ventilation
• Large blowers
• Water circulation equipment

For variable-torque applications, motor speed can be adjusted according to process demand.

This can provide more flexible operation than running the motor continuously at full speed.

---

7. Normal Duty — 1000 HP

The 1000 HP Normal Duty rating provides substantial capacity for general industrial machinery.

Possible applications include:

• Process pumps
• Material-handling systems
• Large fans
• Blowers
• Industrial rotating equipment
• Large auxiliary machinery

Normal Duty applications generally require a substantial motor but do not have the same overload requirements associated with a more demanding Heavy Duty application.

---

8. Heavy Duty — 800 HP

The 800 HP Heavy Duty rating is especially important for equipment with high starting torque or demanding mechanical characteristics.

Examples include:

• Heavy conveyors
• Mining conveyors
• Bulk-material handling
• High-inertia machinery
• Heavy process equipment
• Large mechanical systems

When an application involves frequent starts, heavy loads, high inertia, or aggressive acceleration, the Heavy Duty rating should be considered carefully.

---

9. PowerFlex 755 Series

The PowerFlex 755 is designed as a high-performance industrial AC drive platform.

The series is intended for applications that need more than basic motor speed control.

Depending on the overall system configuration, the platform supports functions associated with:

• Variable-speed control
• Vector control
• Sensorless vector control
• Torque control
• Speed control
• Feedback
• PID process control
• Industrial networking
• Diagnostic functions
• Safety-related options
• Expansion I/O
• Communication options

This makes the platform suitable for complex industrial machines and large automated production systems.

---

10. Product Introduction

The 20G11BD1K2AN0NNNNN is essentially a high-capacity motor-control platform designed to regulate very large AC motors.

The drive converts incoming three-phase electrical power into controlled electrical output for the motor.

Instead of simply applying fixed-frequency power, the drive can control the motor’s operating conditions.

This provides capabilities such as:

• Adjustable speed
• Controlled acceleration
• Controlled deceleration
• Torque management
• Process regulation
• Remote operation
• Network communication
• Fault monitoring
• Diagnostic information

These functions are particularly valuable in large industrial facilities where motors can represent a major part of the plant’s mechanical and electrical infrastructure.

---

11. Embedded EtherNet/IP

The model includes embedded EtherNet/IP capability.

This allows the drive to be integrated into an industrial automation architecture.

A control system can exchange information such as:

For a large plant containing multiple high-power drives, network communication can greatly simplify centralized supervision.

---

12. No Local HIM

The catalog configuration AN0 uses a blank / no-HIM arrangement.

HIM means Human Interface Module.

Unlike a door-mounted-HIM configuration, this model does not include a standard local operator interface as part of the catalog configuration.

This is often appropriate for automated industrial installations where drive operation is normally performed through:

• PLC
• HMI
• SCADA
• Control-room system
• Industrial network
• External programming software

For large electrical rooms, this configuration can also reduce the need for routine operator interaction directly at the drive.

---

13. Advantages of a No-HIM Configuration

A no-HIM configuration can be advantageous when the plant is designed around centralized automation.

Operators can work from a control room while the drive remains inside an electrical area.

This approach can provide:

• Centralized operation
• Centralized fault monitoring
• Reduced operator access to high-power equipment
• Consistent control architecture
• Easier integration with multiple drives

For maintenance, appropriate programming and diagnostic equipment can still be used when direct access is required.

---

14. AC Input With Precharge

The drive is configured with AC input with precharge.

Large AC drives contain substantial DC-link capacitance.

When power is initially applied, the DC bus needs to charge.

The precharge function manages this initial charging process and helps limit the initial current associated with charging the DC-link capacitors.

This is particularly important in a drive with an output capacity exceeding 1100 A.

---

15. DC Terminals

The model includes DC terminals.

The DC bus is an important part of the drive’s internal power-conversion system.

DC terminals can also provide flexibility for specially engineered power-system arrangements.

However, external DC-bus systems must be designed carefully.

Important considerations include:

• DC voltage
• DC current
• Precharge
• Protection
• Isolation
• Grounding
• Fault behavior
• Energy flow
• Equipment compatibility

The DC terminals should therefore be considered part of a complete engineered system rather than treated as an ordinary low-voltage connection.

---

16. EMC Filtering

The model includes EMC filtering.

Large variable frequency drives use high-frequency switching to control motor voltage and current.

This switching can generate electrical interference.

The EMC filter helps reduce conducted interference.

However, good EMC performance also depends on the complete installation.

Important factors include:

• Grounding
• Bonding
• Shielding
• Motor cable construction
• Cable length
• Cable routing
• Control cable separation
• Network cable routing
• Cabinet construction

Proper installation is therefore just as important as the filter itself.

---

17. CM Jumper Removed

The model is configured with the CM jumper removed.

The common-mode configuration affects the electrical relationship between the drive, grounding system, EMC filter, and motor installation.

This is important during replacement work.

A drive with the same horsepower and current rating may still have a different grounding or common-mode configuration.

When replacing an existing drive, the complete configuration should therefore be checked.

---

18. Dynamic Braking

The 20G11BD1K2AN0NNNNN does not include an integrated dynamic-braking transistor.

This means the drive is not configured with internal dynamic braking for dissipating regenerated energy.

This is particularly important for:

• Large conveyors
• High-inertia machines
• Rapid-stop applications
• Large rotating equipment

During deceleration, the motor can return mechanical energy to the DC bus.

If the regenerated energy is excessive, the DC-bus voltage can rise.

Depending on the application, alternative methods may be required, such as:

• Longer deceleration ramps
• External braking equipment
• Regenerative systems
• Mechanical braking
• Alternative energy-management methods

---

19. Mechanical Dimensions

The 20G11BD1K2AN0NNNNN uses a Frame 9 construction.

A typical Frame 9 MCC-style arrangement is approximately:

2453 mm high × 1200 mm wide × 600 mm deep

Some configurations can use greater depth, approximately 800 mm, depending on the equipment arrangement.

For planning purposes, the envelope can therefore be treated as approximately:

2453 × 1200 × 600/800 mm

The exact final cabinet arrangement should always be checked against the applicable mechanical drawing before installation.

---

20. Weight

The exact weight can vary according to the final mechanical configuration.

For this size of Frame 9 drive, a practical planning value is approximately:

1,250–1,270 kg

A commonly listed equipment value for this model is approximately:

1270 kg

Therefore, for transportation and floor-loading calculations, it is sensible to plan around 1270 kg unless the final equipment documentation specifies a different shipping or cabinet weight.

---

21. Mechanical Parameter Table

---

22. Why the Size Matters

A drive weighing approximately 1270 kg is very different from a conventional compact VFD.

The installation project needs to consider:

• Building floor capacity
• Equipment access
• Transportation route
• Door dimensions
• Lifting equipment
• Crane capacity
• Forklift capacity
• Cable entry
• Cable bending radius
• Maintenance space
• Cooling airflow
• Heat dissipation

The drive should therefore be treated as a major piece of electrical infrastructure.

---

23. Large Pump Applications

The model is particularly suitable for large pump systems.

Potential applications include:

• Water-treatment pumps
• Cooling-water pumps
• Process-water pumps
• Industrial circulation pumps
• Mine dewatering pumps

• Process pumping systems

Variable-speed operation allows the pump output to be adjusted to actual process requirements.

---

24. Centrifugal Pump Control

Centrifugal pumps are one of the most natural applications for a high-power variable frequency drive.

A simplified control structure can be:

Pressure Sensor → PID Control → Drive → Motor → Pump → Process

The drive can adjust motor speed based on the pressure or flow feedback.

For example, if system pressure decreases, motor speed can increase.

If demand decreases and pressure begins to rise, motor speed can be reduced.

This provides smoother process regulation.

---

25. Large Fan Applications

Large industrial fans can consume substantial electrical power.

The drive can control fan speed according to actual airflow demand.

Potential applications include:

• Furnace ventilation
• Process exhaust
• Combustion air
• Industrial cooling

Potential equipment includes:

• Belt conveyors
• Transfer systems
• Bulk-material systems
• Storage and reclaim systems
• Large mechanical feeders
• Industrial transport systems

Controlled acceleration can help reduce mechanical stress.

Adjustable speed can also allow the material flow rate to be coordinated with other equipment.

---

32. Water and Wastewater Applications

Large water systems frequently use high-power motors.

Potential applications include:

• Raw-water pumping
• Water circulation
• High-capacity pumping stations
• Wastewater pumping
• Aeration blowers
• Process-water systems
• Cooling-water systems

PID control can be particularly useful for pressure and flow regulation.

---

33. Process-Control Applications

The drive can participate in a closed-loop process-control system.

For example:

Flow Sensor → Process Controller → Drive → Motor → Pump

or:

Pressure Sensor → PID → Drive → Blower → Process

This approach allows motor speed to respond continuously to process requirements.

Such control is useful when process demand changes over time.

---

34. Energy Management Advantages

Variable-speed operation can provide energy-saving potential in applications where the motor does not need to operate continuously at full speed.

This is especially relevant to:

• Centrifugal pumps
• Large fans
• Blowers

In a variable-torque system, reducing speed can substantially reduce power consumption.

Actual savings depend on the entire mechanical system and its operating profile.

Important factors include:

• Operating hours
• Load profile
• Motor efficiency
• Pump or fan characteristics
• System resistance
• Required speed range

---

35. Soft Starting Advantage

A variable frequency drive can provide controlled acceleration.

This can reduce the mechanical shock associated with starting a large motor.

Potential benefits include:

• Reduced starting stress
• Lower mechanical shock
• Controlled acceleration
• Better process control
• Reduced belt stress
• Reduced gearbox shock
• Improved coordination with downstream equipment

For large industrial machines, controlled acceleration can be a significant operational advantage.

---

36. Speed Control Advantage

A fixed-speed motor normally operates at one primary speed.

A variable frequency drive can provide adjustable motor speed.

This is useful when process demand changes.

For example:

This makes the drive more flexible than fixed-speed motor control.

---

37. Centralized Control Advantage

Embedded EtherNet/IP allows the drive to be integrated into centralized automation.

A control room can potentially monitor:

• Motor current
• Motor speed
• Frequency
• Drive status
• Fault status
• Warning status
• Process feedback
• Operating commands

This is particularly useful in large plants with many distributed motors.

---

38. Diagnostic Advantages

Typical information of interest includes:

• Drive status
• Fault conditions
• Warning conditions
• Motor current
• Output frequency
• Speed
• DC-bus information
• Communication status
• Parameter information

For large installations, this type of information can reduce troubleshooting time.

---

39. No-HIM Configuration and Plant Automation

The absence of a local HIM is particularly suitable for centralized automation.

In a large facility, operators may not need to stand next to the drive.

Instead, the control architecture can provide the operating interface.

This approach can be useful when the drive is located:

• Inside an electrical room
• Inside an MCC area
• In a restricted access area
• In a centralized drive room
• In a large industrial plant

---

At approximately 1135 A, thermal management is a major engineering consideration.

The installation should provide sufficient:

• Ventilation
• Airflow
• Heat removal
• Room cooling
• Maintenance access

The cooling path should remain free from excessive dust and contamination.

Temperature should be kept within the permitted operating range.

---

42. Transportation and Installation

Transportation should be planned before the drive arrives at the facility.

---

The drive can adjust blower speed according to actual process demand.

This is particularly useful in:

• Wastewater aeration
• Industrial ventilation
• Pneumatic transport
• Combustion-air systems
• Process-air systems

---

56. Advantages for Conveyors

For large conveyors, controlled acceleration is one of the most valuable characteristics.

A conveyor can be accelerated gradually rather than subjected to an abrupt full-speed start.

This can reduce mechanical shock and improve system operation.

The drive can also provide variable conveyor speed when required by the process.

---

57. Advantages for Mining

Mining equipment often operates under severe mechanical loads.

The large current rating of this drive allows it to control substantial motors.

The drive can be used in systems such as:

• Ore conveyors
• Dewatering pumps

• Conveyors
• Pumps
• Blowers
• Material-handling systems

The ability to adjust speed can help the equipment respond to changing production requirements.

---

59. Advantages for Process Plants

The combination of high-power motor control, PID functionality, and industrial networking makes the drive suitable for large process facilities.

The drive can become part of a complete control loop:

Process Sensor → Controller → Drive → Motor → Machine → Process

This arrangement is useful for systems where motor speed must change continuously according to production conditions.

---

60. Energy Efficiency Considerations

Variable-speed operation can provide substantial energy-saving potential in appropriate applications.

This is particularly relevant to centrifugal pumps and fans.

If process demand decreases, the motor does not necessarily need to continue operating at full speed.

The drive can reduce motor speed.

Potential benefits include:

• Reduced energy consumption
• Reduced throttling
• Reduced mechanical stress
• Better process matching
• Improved operating flexibility

Actual energy savings should be determined from the specific motor, process, operating hours, and load profile.

---

61. Cooling and Thermal Management

The 20G11BD1K2AN0NNNNN is an air-cooled high-power drive.

The installation should provide sufficient cooling airflow.

The electrical room should be designed to remove heat generated by the drive.

Important factors include:

• Ambient temperature
• Room ventilation
• Heat load
• Cooling fan operation
• Dust accumulation
• Airflow restrictions
• Equipment spacing

Thermal management becomes increasingly important as drive current increases.

---

62. Maintenance Considerations

Routine maintenance should consider:

• Cooling airflow
• Fan condition
• Electrical connections
• Grounding
• Cable connections
• Drive status
• Fault history
• Warning history
• Network communication
• Motor current
• Operating temperature

The no-HIM configuration means that centralized software or an appropriate service interface may be used for detailed diagnostics and parameter management.

---

63. Installation Considerations

Before installing this drive, the following should be reviewed:

Electrical Space

The cabinet requires substantial room for installation and servicing.

Floor Loading

Approximately 1270 kg should be considered when evaluating floor capacity.

Ventilation

Forced-air cooling requires adequate airflow.

Cable Routing

Large motor and incoming power cables require appropriate routing and bending space.

67. Final Product Assessment

The 20G11BD1K2AN0NNNNN is a very high-power PowerFlex 755 AC variable frequency drive designed for large industrial motor applications.

Its approximately 1135 A output current provides more capacity than the 1045 A class immediately below it, while its 1100 HP Light Duty, 1000 HP Normal Duty, and 800 HP Heavy Duty ratings make it suitable for a wide range of large industrial equipment.

The model is especially attractive for applications where the motor must be controlled according to changing process requirements.

Large centrifugal pumps, industrial fans, blowers, conveyors, mining systems, cement machinery, water infrastructure, and process equipment are all strong application areas.

The embedded EtherNet/IP capability allows the drive to communicate with centralized automation systems.

This is particularly valuable in large facilities where dozens or hundreds of motors may be monitored from a central control room.

The PID functionality further expands its usefulness for pressure, flow, airflow, and other feedback-controlled processes.

The AC input with precharge and DC terminals provide a suitable architecture for a large industrial drive.

The EMC filter and removed CM jumper configuration also need to be considered as part of the complete electrical installation.

One important limitation is the absence of integrated dynamic braking.

For high-inertia machinery that must stop rapidly, the regenerative-energy behavior of the application should be analyzed before final drive selection.

The physical size is another major consideration.

With a typical Frame 9 envelope of approximately 2453 × 1200 × 600/800 mm and a planning weight of approximately 1270 kg, the drive requires serious mechanical and logistical preparation.

Floor loading, transportation, lifting, ventilation, cable routing, and maintenance space should all be addressed before installation.

Compared with the 20G11BD1K0AN0NNNNN, the target model provides higher current and higher horsepower capability.

Compared with the 20G11BD1K3AN0NNNNN, it provides slightly less capacity while retaining the same general Frame 9 high-power architecture.

This makes the 20G11BD1K2AN0NNNNN a useful middle point for large 480 VAC industrial motor systems.

In practical terms, the model can be summarized as a 480 VAC, three-phase, 1135 A, Frame 9, air-cooled PowerFlex 755 high-power AC drive with 1100 HP Light Duty, 1000 HP Normal Duty, 800 HP Heavy Duty capability, embedded EtherNet/IP, PID control, AC precharge, DC terminals, EMC filtering, removed CM jumper, no integrated dynamic braking, and a blank/no-HIM configuration.

Its primary strengths are very high current capacity, large horsepower capability, industrial network integration, process-control functionality, high-power Frame 9 construction, and suitability for large continuous-duty industrial machinery.

For large-scale pumping, ventilation, mining, cement, material handling, water systems, and process applications, it represents a drive configuration intended for the upper end of conventional industrial AC motor-control requirements.
