1. Product Overview

The Allen-Bradley 20G11BE1K1AN0NNNNN is a high-power PowerFlex 755 AC Packaged Drive designed for large industrial motor-control applications.

It belongs to the PowerFlex 750-Series, specifically the PowerFlex 755 family. This model is intended for large AC motors used in demanding industrial processes where high current capacity, controlled acceleration, variable-speed operation, process control and automation-system integration are required.

The model is designed for a 600 VAC, three-phase power system and has a continuous output current rating of approximately 1,110 A. Its power rating reaches approximately 1,200 HP for Light Duty, 1,100 HP for Normal Duty and 1,000 HP for Heavy Duty.

The model uses a Frame 10, air-cooled construction and a 600 mm deep MCC-style package. It is specified as a Type 1 / IP20 industrial drive.

An important feature of this particular catalog number is the AN0 configuration, which means the drive is supplied without a local HIM. It is therefore particularly suitable for installations where operation and supervision are primarily handled through a PLC, HMI, SCADA system or other centralized control architecture.

The model also uses an EMC-filtered configuration, has the CM jumper removed, and does not include an internal dynamic-braking transistor.

The horsepower-to-kilowatt figures above are approximate engineering conversions based on 1 HP ≈ 0.746 kW. Actual drive selection should be based on the motor nameplate current, duty cycle and application requirements rather than horsepower conversion alone.

The exact overall height and width depend on the packaged configuration and mechanical arrangement. The 600 mm depth is the relevant MCC-style package depth reference. For final cabinet fabrication, transportation and floor-loading calculations, the configuration-specific mechanical drawing should be used.

The weight should likewise be treated as a planning value rather than a certified shipping weight. A drive in this power class is heavy industrial equipment and normally requires mechanical lifting and appropriate floor-loading evaluation.

---

4. Product Introduction

The 20G11BE1K1AN0NNNNN is intended for very large industrial motors.

Compared with smaller variable-frequency drives, this unit is designed to handle substantially higher current and horsepower levels.

A conventional motor starter generally provides basic starting and stopping, whereas a variable-frequency drive can control the motor’s operating speed and torque.

This difference becomes particularly important in large process systems.

A pump may not need full speed at all times.

A large fan may need different airflow depending on production conditions.

A conveyor may need controlled acceleration to prevent mechanical shock.

A blower may need to maintain a specific process pressure.

In these applications, variable-frequency control provides a more flexible way to match motor operation to actual process demand.

The PowerFlex 755 platform is also designed for integration with industrial automation systems, making the drive suitable for applications where motor control needs to be coordinated with a larger production process.

---

5. 600 VAC Power Class

One of the most important characteristics of this model is its 600 VAC three-phase rating.

This differentiates it from many 480 VAC PowerFlex configurations.

The 600 V class is commonly encountered in industrial electrical systems where large motor loads require higher operating voltage.

Using a higher voltage for a given motor power can help reduce the current required compared with an equivalent lower-voltage system.

However, the drive still has a very substantial 1,110 A output-current capability, placing it firmly in the large industrial equipment category.

---

6. 1,110 A Output Current

The 1,110 A output rating is one of the defining characteristics of the 20G11BE1K1AN0NNNNN.

This current capacity allows the drive to control very large motors.

Rating	Motor Capacity
Light Duty	1,200 HP
Normal Duty	1,100 HP
Heavy Duty	1,000 HP

Approximate metric equivalents are:

Duty	HP	Approx. kW
Light Duty	1,200 HP	895 kW
Normal Duty	1,100 HP	820 kW
Heavy Duty	1,000 HP	746 kW

These are extremely large motor ratings.

The selection process should therefore include detailed evaluation of motor nameplate current, overload capability, starting requirements, inertia, acceleration time, process load and environmental conditions.

---

7. Frame 10 Construction

The 20G11BE1K1AN0NNNNN uses Frame 10 construction.

Frame size is important because it influences the physical arrangement of the power electronics and cooling system.

A Frame 10 drive is substantially larger than the compact frames normally used for small machine applications.

The Frame 10 structure is designed around high-power industrial requirements.

It provides the physical space necessary for large power components, high-current connections, cooling equipment and associated electrical assemblies.

---

8. Air-Cooled Design

The drive uses forced-air cooling.

Large semiconductor power devices generate considerable heat during operation.

The cooling system transfers this heat away from the power electronics.

Proper installation therefore requires adequate airflow around the equipment.

Important environmental considerations include:

• Room temperature
• Ventilation
• Air circulation
• Dust concentration
• Filter condition
• Fan condition
• Heat generated by neighboring equipment

A drive can have excellent electrical specifications but still suffer reliability problems if the electrical room is too hot or poorly ventilated.

---

9. Type 1 / IP20 Protection

The packaged configuration is specified as Type 1 / IP20.

This type of construction is intended for appropriate indoor electrical installations.

It should not be treated as an outdoor or water-resistant enclosure.

The installation environment should be protected from:

• Rain
• Direct water
• Condensation
• Excessive humidity
• Heavy dust
• Corrosive chemicals
• Conductive contamination

For severe environments, additional enclosure or environmental protection may be necessary.

---

10. 600 mm Deep MCC-Style Package

The drive is associated with a 600 mm deep MCC-style package.

This is particularly useful for centralized electrical-room installations.

Mechanical Parameter	Specification
Model	20G11BE1K1AN0NNNNN
Frame	10
Package Type	MCC Style
Nominal Package Depth	Approximately 600 mm
Width	Configuration Dependent
Height	Configuration Dependent
Enclosure	Type 1
Protection	IP20
Cooling	Forced Air
Installation	Indoor Industrial Electrical Room
Maintenance Space	Required
Cable Space	Required
Ventilation Space	Required

The 600 mm dimension should not be interpreted as the complete installation footprint.

A large drive also requires space for:

• Incoming power cables
• Motor cables
• Cable bending radius
• Ventilation
• Service access
• Door clearance
• Maintenance operations
• Lifting and replacement activities

---

11. Weight and Handling

Because of its very high power rating, the 20G11BE1K1AN0NNNNN should be considered heavy industrial equipment.

A reasonable planning classification is approximately 1,300 kg class, but the exact weight should be confirmed against the final packaged configuration and shipping documentation.

Mechanical Item	Specification
Model	20G11BE1K1AN0NNNNN
Depth	Approx. 600 mm
Width	Configuration Dependent
Height	Configuration Dependent
Planning Weight	Approx. 1,300 kg class
Certified Final Weight	Verify by configuration
Shipping Weight	May be higher
Floor Loading	Must Be Evaluated
Lifting	Mechanical Equipment Required
Handling	Heavy-Duty Industrial Handling

For plant installation, the floor, lifting equipment, access route and unloading procedure should all be evaluated before delivery.

---

12. AN0 Configuration — No HIM

A major characteristic of this particular model is the AN0 configuration.

The unit is supplied without a local HIM.

HIM means Human Interface Module.

Unlike a drive with an integrated Enhanced LCD HIM, the AN0 version is intended primarily for integration into a larger control architecture.

This configuration can be attractive when:

• The drive is installed inside a centralized MCC
• A PLC controls the drive
• A plant HMI provides operator control
• SCADA provides supervision
• Local manual operation is not required
• The drive is part of a highly automated production system

---

13. Centralized Control Architecture

The absence of a local HIM does not mean that the drive cannot be monitored or controlled.

Instead, control can be performed through the plant automation system.

A typical architecture could be:

PLC

↓

Ethernet/IP

↓

PowerFlex 755

↓

1,100 HP-Class Motor

↓

Industrial Process

The operator can interact with the process through a plant HMI or SCADA system.

This approach is common in large automated facilities.

---

14. Embedded Ethernet/IP

The PowerFlex 755 platform provides embedded Ethernet/IP integration.

This is particularly valuable in large plants because the drive can become part of the same automation infrastructure as other industrial devices.

Potential communication functions include:

• Drive status
• Speed reference
• Start/stop commands
• Fault information
• Alarm information
• Operating parameters
• Diagnostic information
• Process-related control data

This allows the drive to be managed as part of a larger automated system instead of operating as an isolated motor controller.

---

15. AC Input With Precharge

The model uses an AC input with precharge arrangement and provides DC terminals.

The incoming three-phase AC supply is processed by the drive’s input section and converted into the internal DC bus.

The DC bus then supplies the inverter section.

A simplified power path is:

600 VAC Three-Phase Input

↓

Input / Precharge

↓

DC Bus

↓

Power Inverter

↓

Variable-Frequency AC Output

↓

Large AC Motor

This architecture allows the drive to regulate the frequency and voltage supplied to the motor.

---

16. EMC Filter

The model is specified with an EMC filter.

Electromagnetic compatibility is particularly important in large industrial installations.

The high-frequency switching action of a VFD can generate electrical noise.

The EMC filter helps manage this noise as part of the overall drive design.

However, proper installation is still essential.

The complete system should consider:

• Grounding
• Bonding
• Motor cable construction
• Shielding
• Cable routing
• Separation of power and signal wiring
• Communication cable routing
• Cabinet construction

The EMC filter should therefore be viewed as one part of the complete EMC strategy.

---

17. CM Jumper Removed

The catalog configuration specifies the CM jumper removed.

This is an important electrical configuration detail.

Common-mode behavior can influence grounding, leakage-current characteristics and EMC performance.

When replacing an existing drive, the complete catalog number should always be compared.

A drive with the same current and voltage rating can still have different electrical configuration options.

---

18. Dynamic Braking

The 20G11BE1K1AN0NNNNN is specified with no internal dynamic-braking transistor.

Parameter	Specification
Model	20G11BE1K1AN0NNNNN
Dynamic Braking	None
Internal Braking Transistor	None
Regenerative Operation	Requires Application Evaluation
High-Inertia Loads	Requires Engineering Review
Rapid Deceleration	External Solution May Be Required

This is important for large rotating equipment.

If the application requires rapid stopping of a high-inertia load, the engineering team should evaluate the complete braking system.

Possible approaches can include:

• Longer deceleration time
• Mechanical braking
• External braking equipment
• Regenerative drive architecture

The correct approach depends on the mechanical load and stopping requirements.

---

19. Large Pump Applications

Large pumps are one of the most suitable application categories for a drive of this size.

Potential applications include:

• Raw-water pumping
• Cooling-water pumping
• Process-water pumping
• Mine dewatering
• High-capacity wastewater pumping
• Industrial circulation systems
• Water-transfer systems

Variable-speed operation can allow pump speed to follow actual process requirements.

For variable-torque pump applications, this can also create significant energy-saving opportunities compared with continuously operating a motor at full speed.

---

20. Large Fan Applications

Large fans can consume substantial amounts of electrical power.

The drive can be applied to:

• Industrial exhaust fans
• Mine ventilation fans
• Process ventilation
• Cooling fans
• Combustion-air fans
• Dust-collection systems
• Large building or plant ventilation

Variable-speed control allows airflow to be adjusted according to process requirements.

---

21. Large Blower Applications

Industrial blowers often operate continuously and may require significant horsepower.

Potential applications include:

• Aeration blowers
• Process-air blowers
• Pneumatic conveying
• Industrial combustion
• Ventilation
• Chemical-process air systems

The drive allows the blower speed to be controlled according to process demand.

---

22. Mining Applications

Mining operations frequently require extremely large motors.

The 20G11BE1K1AN0NNNNN can be considered for applications such as:

• Large conveyors
• Mine ventilation
• Dewatering
• Material handling
• Processing equipment
• Crushing and auxiliary systems

The high current rating provides substantial capacity for large motor loads.

Environmental conditions should nevertheless be carefully evaluated because mining facilities can expose electrical equipment to dust, vibration and temperature extremes.

---

23. Cement Plant Applications

Large cement facilities contain many high-power motors.

Possible applications include:

• Large process fans
• Exhaust fans
• Conveyors
• Material-handling systems
• Cooling systems
• Large pumps
• Process blowers

A centralized PowerFlex 755 installation can provide controlled motor operation while integrating with the plant automation system.

---

24. Steel and Metal Processing

Large steel and metal-processing facilities often contain substantial motor loads.

Potential applications include:

• Cooling-water systems
• Large fans
• Blowers
• Conveyors
• Material handling
• Auxiliary process equipment

The drive’s high current capacity makes it suitable for very large industrial motors where a smaller drive would be insufficient.

---

25. Water and Wastewater Applications

Large water infrastructure can involve very high motor powers.

Potential applications include:

• Intake pumps
• Transfer pumps
• High-capacity wastewater pumps
• Flood-control systems
• Cooling-water pumps
• Industrial process-water systems

Variable-speed operation allows the pumping system to respond to changing demand.

---

26. Conveyor Applications

Large conveyors can place significant demands on motor-control equipment.

A heavily loaded conveyor may require controlled acceleration to avoid excessive mechanical stress.

The drive can be used to provide controlled speed ramps.

This can help reduce sudden torque transfer through:

• Gearboxes
• Couplings
• Shafts
• Bearings
• Belts
• Chains

For very high-inertia conveyors, acceleration and deceleration requirements should be evaluated carefully.

---

27. Advantages of the 20G11BE1K1AN0NNNNN

27.1 Very High Power Capacity

The ability to handle approximately 1,110 A makes this drive suitable for extremely large industrial motors.

This is its primary advantage.

---

27.2 600 VAC Industrial Voltage Class

The 600 VAC class is appropriate for many large industrial power systems.

It provides a higher-voltage architecture for high-power motor applications.

---

27.3 1,200 HP Light-Duty Capability

The approximately 1,200 HP Light-Duty rating places the model in the very-high-power category.

This makes it appropriate for large industrial machinery.

---

27.4 1,100 HP Normal-Duty Capability

The approximately 1,100 HP Normal-Duty rating provides substantial capacity for continuous industrial applications.

---

27.5 1,000 HP Heavy-Duty Capability

The approximately 1,000 HP Heavy-Duty rating gives the drive additional capability for demanding load cycles.

---

27.6 Ethernet/IP Integration

Embedded Ethernet/IP allows the drive to become part of a centralized industrial automation system.

This is particularly valuable for large plants where many drives need to be managed through common control infrastructure.

---

27.7 No-HIM Configuration

The AN0 configuration can be an advantage rather than a disadvantage in centralized automation systems.

It avoids the need for a local operator interface when all operation is intended to occur through:

• PLC
• HMI
• SCADA
• DCS
• Centralized control architecture

---

27.8 MCC-Style Package

The 600 mm deep MCC-style configuration is suitable for centralized electrical rooms and motor-control installations.

---

27.9 Forced-Air Cooling

The air-cooled design is suitable for properly engineered industrial electrical rooms.

---

27.10 EMC Filtering

The integrated EMC filtering supports electrical-noise management in properly designed installations.

---

28. Energy Efficiency Advantages

Variable-frequency drives can provide significant energy-saving opportunities in variable-torque applications.

This is particularly relevant to:

• Pumps
• Fans
• Blowers

For these loads, the required power can fall substantially when operating speed is reduced.

For example, if a pump only needs reduced flow, reducing motor speed can be more efficient than maintaining full speed and using a mechanical throttling device.

The actual energy-saving result depends on the complete system.

Important factors include:

• Motor efficiency
• Pump efficiency
• Fan efficiency
• System curve
• Operating hours
• Load profile
• Process requirements
• Control strategy

Therefore, a specific energy-saving percentage should not be assumed without an application study.

---

29. Automation Advantages

The PowerFlex 755 platform is designed for integration with industrial control systems.

A centralized architecture can look like:

Plant Control System

↓

Ethernet/IP Network

↓

PowerFlex 755

↓

1,100 HP-Class Motor

↓

Process Equipment

The drive can therefore participate in the plant’s overall control strategy.

This is particularly useful in large facilities where dozens or hundreds of motors may need coordinated control.

---

30. Maintenance Characteristics

Because the model does not include a local HIM, maintenance personnel will generally rely more heavily on the plant control system and appropriate service equipment for monitoring and commissioning.

This configuration can be particularly suitable when the electrical room is already equipped with:

• Centralized HMI
• SCADA
• Engineering workstation
• PLC diagnostics
• Network monitoring
• Maintenance communication infrastructure

The absence of a local HIM is therefore best understood as a configuration choice rather than a limitation of the drive platform.

---

31. Installation Considerations

A drive rated around 1,110 A requires substantial electrical and mechanical infrastructure.

Installation Factor	Requirement
Input Voltage	600 VAC
Input Phase	3 Phase
Output Current	1,110 A
Input Protection	Correctly Engineered
Motor Conductors	Correctly Sized
Grounding	Properly Engineered
EMC	System-Level Design
Cooling	Adequate Forced Air
Mechanical Support	Heavy-Duty
Floor Loading	Evaluate
Lifting	Mechanical Handling
Cable Bending Radius	Provide Adequate Space
Service Access	Required

---

32. Electrical Installation

At this current level, electrical installation should be treated as a major engineering project.

Important considerations include:

• Incoming feeder sizing
• Circuit protection
• Short-circuit current rating
• Busbar capacity
• Cable ampacity
• Motor conductor sizing
• Grounding
• Cable termination
• Harmonic considerations
• EMC
• Heat generation
• Motor cable length
• Electrical clearances

The VFD must be coordinated with the upstream electrical distribution system and the motor.

---

33. Mechanical Installation

The approximate 1,300 kg-class planning weight means that mechanical handling must be considered from the beginning of the project.

The installation team should evaluate:

• Truck access
• Unloading
• Plant entrances
• Door dimensions
• Lifting equipment
• Floor loading
• Cabinet positioning
• Maintenance clearance
• Replacement access
• Ventilation

A heavy industrial drive should not be positioned solely based on electrical cabinet dimensions.

The complete service envelope must be considered.

---

34. Environmental Considerations

For reliable operation, the installation environment should be controlled.

Particular attention should be given to:

• Temperature
• Humidity
• Dust
• Air quality
• Corrosive gases
• Vibration
• Ventilation
• Altitude

Large drives generate substantial heat.

If several high-power drives are installed in the same electrical room, the combined heat load can become significant.

The room’s HVAC and ventilation system should therefore be sized accordingly.

---

---

43. Advantages of the No-HIM Configuration

At first glance, the absence of a local HIM may appear to be a disadvantage.

For a highly automated plant, however, it can actually be an appropriate configuration.

If the drive is controlled through a PLC and HMI, operators may not need a local keypad.

This can simplify the physical installation and place operator interaction in a centralized control room.

The AN0 configuration is therefore particularly appropriate for:

• Automated factories
• Process plants
• Centralized MCC rooms
• Water-treatment plants
• Mining facilities
• Cement plants
• Large material-handling systems
• Centralized pump stations

---

44. Local Control vs Centralized Control

Feature	AN0 Configuration
Local HIM	No
Local Numeric Keypad	No
PLC Control	Suitable
HMI Control	Suitable
SCADA Integration	Suitable
Ethernet/IP	Available
Centralized Operation	Excellent
Automated Plant	Excellent
Local Standalone Operation	Less Convenient
Maintenance Through Central System	Suitable

If local technician interaction is a major requirement, a configuration with an Enhanced LCD HIM may be more appropriate.

If centralized automation is the priority, the AN0 version can be an excellent choice.

---

45. Maintenance Considerations

The absence of a local HIM means the plant should have an appropriate maintenance strategy.

Recommended provisions include:

• Accessible control-system diagnostics
• Ethernet/IP network monitoring
• Drive parameter backup
• Maintenance workstation access
• Fault-history management
• Appropriate spare-parts planning
• Preventive inspection
• Cooling-system inspection
• Electrical connection inspection

For a drive of this size, planned maintenance is preferable to waiting for a failure.

---

46. Cooling and Thermal Management

Large power drives generate heat.

The installation should therefore consider the complete thermal environment.

For example, if several 1 MW-class drives are installed in one room, the combined heat output can become a significant HVAC load.

The electrical room should provide:

• Adequate ventilation
• Controlled temperature
• Sufficient air circulation

50. Product Selection Summary

The Allen-Bradley 20G11BE1K1AN0NNNNN is best suited to applications requiring a combination of 600 VAC operation, 1,110 A output capacity and extremely high motor horsepower.

Its 1,200 HP Light-Duty, 1,100 HP Normal-Duty and 1,000 HP Heavy-Duty ratings place it firmly in the high-power industrial category.

The Frame 10, forced-air-cooled architecture and 600 mm deep MCC-style package are appropriate for large centralized electrical installations.

The AN0 configuration makes the unit particularly suitable for centralized automation environments because it does not include a local HIM.

Instead, control and monitoring can be handled through the plant’s automation infrastructure.

The embedded Ethernet/IP capability is particularly useful when the drive needs to communicate with PLCs, HMIs, SCADA systems and other industrial control equipment.

The EMC filter and CM-jumper configuration are also important considerations when integrating the drive into a large industrial electrical system.

Because the drive does not have an internal dynamic-braking transistor, applications involving rapid stopping of high-inertia loads require additional engineering.

The equipment is physically large and heavy. The approximate 600 mm package depth and 1,300 kg-class planning weight should be considered when designing the electrical room, MCC, floor structure, lifting procedure and maintenance area.

The strongest application areas include large pumps, large fans, industrial blowers, mining conveyors, mine dewatering systems, cement plants, steel and metal-processing facilities, water-treatment plants, wastewater facilities and large material-handling systems.

For centralized automated facilities, the AN0 configuration can be particularly practical because operators can control the drive through the plant automation system rather than requiring a local keypad at the drive itself.

Overall, the 20G11BE1K1AN0NNNNN is a very-high-power PowerFlex 755 AC drive for 600 VAC industrial motor applications, intended for large-scale machinery where high current capacity, variable-speed control, automation integration and industrial-duty construction are more important than compact size or local standalone operation.
