Allen-Bradley 20G1ABC650AN0NNNNN PowerFlex 755 AC Drive — Detailed Product Specifications, Applications, Advantages and Related Models

The Allen-Bradley 20G1ABC650AN0NNNNN is a high-power air-cooled AC drive from the PowerFlex 755 series. It is designed for large industrial motor-control applications where high current capacity, adjustable-speed operation, industrial networking, reliable acceleration and deceleration, and integration into larger automation systems are required.

This model belongs to the 650 A class and provides 400 kW Low Duty, 355 kW Normal Duty, and 315 kW Heavy Duty ratings. It uses a 400 VAC, three-phase input, Frame 8 construction, a 600 mm deep MCC-style configuration, forced-air cooling, AC input with precharge, and embedded EtherNet/IP.

A particularly important characteristic of this exact catalog number is the AN0 configuration. The drive is supplied with no local HIM, making it a suitable choice for installations where the drive is primarily controlled and monitored through an automation system or where a separate local operator interface is not required.

---

1. Basic Product Information

The dimensions and weight should be treated as approximate Frame 8 reference values for the 600 mm deep MCC-style configuration. Actual shipping or installed dimensions can vary depending on the complete enclosure arrangement, accessories, mounting arrangement, and packaging.

---

2. Product Series and Brand

Brand: Allen-Bradley

Series: PowerFlex 755

Product Family: PowerFlex

Model: 20G1ABC650AN0NNNNN

The PowerFlex 755 series is intended for demanding industrial motor-control applications where a basic variable-frequency drive is not enough.

It is designed around a modular industrial architecture and can be used for large motors, complex production machinery, process equipment, conveyors, pumps, fans, blowers, compressors, and other large rotating equipment.

The 20G1ABC650AN0NNNNN represents one of the higher-capacity 400 VAC Frame 8 configurations in the 600 mm deep MCC-style group.

---

3. Product Model Interpretation

The catalog number 20G1ABC650AN0NNNNN provides several useful clues about the configuration.

650 — Current Class

The 650 section identifies the drive’s 650 A current class.

This puts the model above the 460 A, 540 A, and 567 A versions and below the larger 750 A and 770 A configurations within the same general high-power family.

The 650 A class is intended for substantial industrial motors and mechanical systems.

---

AN — Configuration

The AN configuration belongs to the earlier configuration group of this PowerFlex 755 product family.

One of the important characteristics of this configuration is the CM jumper removed arrangement.

---

0 — No HIM

The 0 configuration indicates Blank / No HIM.

This is an important distinction when comparing the model with AN2, AN4, JN2, or JN4 versions.

The drive does not include the local Enhanced LCD HIM as part of this catalog configuration.

That makes the model especially suitable for applications where:

• The drive is controlled from a PLC.
• The drive is integrated into a plant network.
• Local keypad operation is not required.
• A cabinet-mounted operator interface is provided separately.
• Multiple drives are managed from a centralized HMI or SCADA system.

---

4. Detailed Electrical Parameters

---

5. 400 VAC Three-Phase Input

The 20G1ABC650AN0NNNNN is designed for a 400 VAC three-phase power system.

This makes it appropriate for many industrial power-distribution systems using 400 VAC-class three-phase supplies.

The three-phase input arrangement is particularly appropriate for high-power industrial motors because the drive is intended to handle substantial motor power without relying on low-voltage, single-phase distribution.

For an actual installation, the complete electrical system should be evaluated, including:

• Incoming supply capacity
• Short-circuit conditions
• Upstream protection
• Disconnect equipment
• Cable size
• Grounding
• Motor cable length
• Harmonic performance
• EMC requirements
• Cabinet thermal conditions
• Ambient temperature

The drive’s 650 A class means that upstream electrical equipment must be selected carefully.

---

6. 650 A High-Current Capacity

The 650 A current class is one of the most significant characteristics of this model.

This is not a small or medium industrial inverter.

It is intended for large motors and high-capacity mechanical systems.

Typical applications include:

• Large water pumps
• Cooling-water pumps
• Large fans
• Industrial blowers
• Heavy conveyors
• Bulk material handling
• Large mixers
• Process machinery
• Compressors
• Production equipment
• Large rotating machinery

The 650 A class provides additional capacity compared with the 567 A version, making it attractive when the motor current is approaching the upper end of the smaller Frame 8 configurations.

---

7. Low Duty, Normal Duty and Heavy Duty Ratings

The model has three major application ratings.

These ratings are important because the correct drive selection should be based on the actual motor current and load characteristics, rather than simply choosing a drive from the motor’s nominal kW rating.

For example, a large centrifugal pump may operate primarily as a variable-torque load and may be evaluated against the higher Low Duty rating.

A conveyor with frequent acceleration and substantial breakaway torque may require a lower Heavy Duty rating.

A process machine with changing mechanical loads may fall between these operating categories and needs to be evaluated carefully.

---

8. 400 kW Low Duty Capability

The 400 kW Low Duty rating is a major advantage for large variable-torque applications.

Variable-torque loads commonly include:

• Centrifugal pumps
• Fans
• Blowers
• Cooling systems
• Air-handling equipment

In these applications, the motor load changes with speed.

The ability to operate a motor at an appropriate speed rather than continuously at maximum speed can provide better process control and potentially reduce energy consumption.

---

9. 355 kW Normal Duty Capability

The 355 kW Normal Duty rating provides a strong operating point for general industrial machinery.

This rating is useful when the application requires more consistent motor loading than a typical variable-torque pump or fan.

Possible applications include:

• Conveyors
• Material handling
• Production machinery
• Large pumps
• Mixers
• Processing equipment
• General industrial machinery

---

10. 315 kW Heavy Duty Capability

The 315 kW Heavy Duty rating is important for applications where the motor experiences greater torque demand or overload conditions.

Heavy-duty applications may involve:

• High breakaway torque
• Frequent acceleration
• High mechanical inertia
• Changing mechanical loads
• Repeated starting and stopping
• Heavy material movement
• Large mechanical resistance

The Heavy Duty rating should always be evaluated against the motor nameplate current and the actual mechanical duty cycle.

---

11. AC Input with Precharge

The model uses an AC input with precharge and no DC terminals.

The precharge arrangement is particularly important in a high-power drive.

The internal DC bus contains energy-storage components, and the precharge circuit helps manage the initial charging process when the drive is energized.

This reduces the stress associated with uncontrolled capacitor charging and contributes to a more controlled startup of the drive’s DC bus.

For a drive in the 650 A class, this is a significant part of the overall power architecture.

---

12. No DC Terminals

The standard catalog configuration does not provide external DC terminals.

This is important when designing the electrical system.

An engineer should not assume that an external DC bus or shared DC-bus connection is available simply because the drive contains an internal DC bus.

The system should be designed according to the exact catalog configuration and the intended application architecture.

---

13. EMC Filtering

The drive is supplied with a filtered configuration.

EMC filtering is particularly important in industrial environments where high-power switching equipment operates close to:

• PLC systems
• Instrumentation
• Sensors
• Communication equipment
• Analog control circuits
• Measurement equipment
• Other variable frequency drives

The filtering arrangement helps manage conducted electrical noise.

However, correct installation remains essential.

Good grounding, cabinet bonding, cable separation, motor cable routing, and proper shield termination are still important even when the drive includes filtering.

---

14. CM Jumper Removed

The 20G1ABC650AN0NNNNN has the CM jumper removed configuration.

This is an important technical distinction between the AN and JN configurations.

The common-mode and grounding/filtering arrangement can influence the way high-frequency electrical currents behave within the drive, motor cable, motor, and grounding system.

Therefore, this setting should not be changed casually.

It should be considered together with:

• Grounding system
• Motor insulation
• EMC requirements
• Motor cable construction
• Cable length
• Installation environment
• Leakage current requirements

The exact installation arrangement should be checked before commissioning.

---

15. Dynamic Braking

The standard configuration provides no dynamic braking.

This does not mean that the drive cannot decelerate a motor.

It means that a dedicated dynamic braking arrangement is not included as part of this standard catalog configuration.

For applications involving large inertia and rapid stopping, braking requirements should be evaluated separately.

Potentially demanding applications include:

• Large conveyors
• Centrifuges
• Large fans
• High-inertia rolls
• Rapid indexing equipment
• Heavy rotating machinery

If the motor must stop very quickly, the mechanical energy stored in the rotating system can become substantial.

In such applications, the braking strategy must be evaluated during the drive-selection stage.

---

16. Embedded EtherNet/IP

The 20G1ABC650AN0NNNNN includes embedded EtherNet/IP.

This is particularly useful for centralized industrial control.

The drive can participate in an automation network where the control system exchanges information such as:

• Start commands
• Stop commands
• Speed reference
• Actual speed
• Output frequency
• Current
• Drive status
• Fault status
• Warning status
• Diagnostic information

This architecture is especially useful when the installation contains many drives.

Instead of providing a separate local operator interface for every drive, a plant can use centralized control stations, operator terminals, or supervisory systems.

---

17. Blank / No HIM Configuration

The AN0 configuration has no HIM.

This can actually be an advantage in a large automated installation.

A drive does not always need a permanent local keypad.

For example, a large production facility may have:

• A central control room
• A PLC-based control system
• A plant HMI
• A SCADA system
• A remote maintenance workstation

In such an environment, a local HIM may provide little additional value.

The AN0 version can therefore be a practical choice when the drive is intended to operate as part of a larger automation system.

---

18. Product Introduction

The Allen-Bradley 20G1ABC650AN0NNNNN is a high-power PowerFlex 755 air-cooled AC drive designed for large three-phase industrial motors.

Its 650 A current class and 400/355/315 kW duty ratings make it suitable for substantial industrial equipment.

The drive combines high-power motor control with embedded EtherNet/IP, making it suitable for integration into automated production systems.

Its 600 mm deep MCC-style construction is intended for industrial electrical rooms and motor-control-center environments where high-power drives need to be installed in a structured electrical system.

The absence of a local HIM makes this model particularly attractive for centralized control architectures.

---

19. Mechanical Parameters

Because this is a large Frame 8 drive, mechanical installation requires careful planning.

The approximately 623 kg weight should be taken seriously during transportation, lifting, positioning, and cabinet installation.

The installation structure must be capable of supporting the actual equipment weight.

---

20. Dimensions and Space Requirements

The approximate physical dimensions are:

2102 mm high × 606 mm wide × 600 mm deep

This is a substantial piece of electrical equipment.

The 600 mm deep MCC-style arrangement can be advantageous when the electrical room is designed around standardized MCC dimensions.

However, the nominal cabinet depth should not be treated as the complete installation envelope.

Additional space may be required for:

• Power cable bending
• Motor cable entry
• Grounding conductors
• Control wiring
• Network cables
• Ventilation
• Service access
• Door operation
• Maintenance
• Removal of internal components

The final enclosure design should therefore include adequate working space rather than simply allocating a 600 mm box around the drive.

---

21. Cooling System

The 20G1ABC650AN0NNNNN is air cooled and uses forced airflow for thermal management.

This makes it practical for conventional industrial electrical rooms without requiring a dedicated liquid-cooling system.

However, a high-power drive generates significant heat.

The installation should therefore provide:

• Adequate airflow
• Correct ventilation
• Appropriate cabinet temperature
• Clean air passages
• Proper fan operation
• Sufficient clearance
• Suitable ambient conditions

Dust accumulation can reduce cooling performance over time.

For installations in dusty industrial environments, regular inspection and maintenance of the cooling system are particularly important.

---

22. Main Applications

22.1 Large Pump Systems

Large pumps are one of the strongest application areas for this drive.

The variable-speed architecture allows the pump speed to be adjusted according to the required flow or process condition.

Typical applications include:

• Water treatment
• Industrial water circulation
• Cooling-water systems
• Process pumping
• Wastewater systems
• Large irrigation systems
• Industrial utilities

For centrifugal pumps, variable-speed operation can be particularly effective because pump power demand changes substantially with speed.

---

22.2 Large Fans

Large fans can also make good use of the drive.

Applications include:

• Industrial ventilation
• Furnace ventilation
• Exhaust systems
• Dust collection
• Process cooling
• Air-handling equipment
• Large building ventilation

Controlling fan speed can provide better process control than simply operating the motor at full speed continuously.

---

22.3 Large Blowers

Large blowers used in industrial processes can benefit from adjustable speed.

Examples include:

• Combustion air systems
• Process air
• Dust collection
• Pneumatic conveying
• Industrial ventilation
• Waste treatment

The 650 A capacity provides substantial room for large blower motors.

---

22.4 Conveyor Systems

Heavy conveyors are another important application.

Large conveyors can have considerable mechanical inertia and may need controlled acceleration to prevent:

• Belt shock
• Mechanical stress
• Product movement
• Gearbox stress
• Coupling stress

The drive can provide controlled motor acceleration and adjustable operating speed.

Typical installations include:

• Mining
• Cement
• Steel
• Aggregate
• Ports
• Warehouses
• Bulk material handling

---

22.5 Large Mixers

Industrial mixers can experience changing torque as material characteristics change.

The drive can provide controlled speed operation and support integration into an automated process.

Applications include:

• Chemical processing
• Mineral processing
• Food processing
• Material blending
• Industrial mixing

---

22.6 Compressors

Selected large compressor applications can also benefit from the drive.

The final suitability depends on:

• Compressor type
• Motor current
• Starting torque
• Operating speed range
• Load profile
• Acceleration time
• Process requirements

For compressor applications, proper motor and drive sizing is especially important.

---

22.7 Production Machinery

The drive is also appropriate for large automated production equipment.

Its embedded EtherNet/IP capability makes it useful where motor control must be coordinated with other automation equipment.

Examples include:

• Processing lines
• Material-handling machinery
• Large machine tools
• Production equipment
• Manufacturing systems
• Continuous-process equipment

---

23. Major Product Advantages

23.1 Very High Power Capacity

The most obvious advantage is the drive’s large capacity.

With:

• 650 A
• 400 kW LD
• 355 kW ND
• 315 kW HD

it is suitable for large industrial motors.

---

23.2 Strong Variable-Speed Control

The PowerFlex 755 architecture provides adjustable-speed motor control suitable for a wide variety of industrial loads.

This can improve process control compared with fixed-speed operation.

---

23.3 Embedded EtherNet/IP

The integrated network interface simplifies integration into a modern industrial control system.

This is particularly valuable in facilities where drive data must be exchanged with centralized automation equipment.

---

23.4 No-HIM Configuration

The absence of a local HIM can be an advantage when the plant uses centralized control.

It can reduce unnecessary local operator hardware and create a cleaner electrical-cabinet arrangement.

---

23.5 High-Power Frame 8 Architecture

Frame 8 provides the physical scale required for high-capacity industrial drives.

It accommodates the larger power components and cooling requirements associated with this power class.

---

23.6 Air-Cooled Design

Air cooling is familiar to maintenance teams and does not require liquid-cooling infrastructure.

It can therefore be practical for conventional industrial installations.

---

23.7 Multiple Duty Ratings

The three duty levels provide flexibility when selecting the drive for different load types.

---

23.8 600 mm Deep MCC Configuration

The 600 mm deep MCC-style construction can simplify integration into appropriately designed industrial electrical systems.

---

23.9 Filtered Configuration

The filtered arrangement can help manage electrical noise in industrial installations.

---

24. Five Same-Series or Closely Related Models

The following five models are useful alternatives or comparison points for the 20G1ABC650AN0NNNNN.

The first three models are particularly useful when comparing different current capacities.

The 20G1ABC567AN0NNNNN is the smaller step, while the 20G1ABC750AN0NNNNN provides additional current and power capacity.

The 20G1ABC650JN0NNNNN has essentially the same basic electrical rating but represents the later JN configuration.

The 20G1ALC650AN0NNNNN is useful when the electrical design requires a deeper 800 mm MCC-style arrangement.

---

25. Five Popular Allen-Bradley Models

These models are useful for comparing the most common high-power 400 VAC configurations.

The 460 A and 540 A models provide lower current capacity.

The 567 A model sits immediately below the 650 A class.

The 650 A version provides a strong balance between large motor capacity and the physical Frame 8 platform.

The 750 A version moves into an even higher current and power range.

---

26. 20G1ABC650AN0NNNNN vs. 20G1ABC650JN0NNNNN

These two models are very closely related.

The electrical ratings are essentially the same.

The most important configuration difference is the CM jumper arrangement.

The AN0 version has the CM jumper removed, while the JN0 version has the CM jumper installed.

This distinction can matter when designing the grounding, EMC, motor-cable, and installation architecture.

---

27. 20G1ABC650AN0NNNNN vs. 20G1ABC650AN2NNNNN

The principal difference is the operator interface.

The AN0 version is the no-HIM configuration.

The AN2 version adds an Enhanced LCD Full Numeric HIM.

For centralized automated systems, AN0 can be a clean and practical solution.

For installations where technicians frequently need to operate or configure the drive locally, AN2 may be more convenient.

---

28. 20G1ABC650AN0NNNNN vs. 20G1ABC650AN4NNNNN

The AN4 configuration is better suited to installations where local operator access is important.

The AN0 configuration is more appropriate when the drive is intended to be controlled remotely.

---

29. Comparison with the 567 A and 750 A Versions

The 650 A version is an interesting middle point.

It provides a significant increase over the 567 A configuration while remaining below the 750 A class.

For a motor whose current requirements fall comfortably within the 650 A range, this can provide a practical balance between capacity and system size.

---

30. Application Selection Guide

---

31. Advantages of the No-HIM Configuration

The absence of a local HIM can look like a disadvantage at first, but in many modern industrial installations it can actually be useful.

A centralized control architecture may already include a plant HMI or SCADA system.

In such an installation, local drive keypads may not be necessary.

The AN0 configuration can therefore be suitable when:

• Operators work from a central control room.
• Drives are managed through EtherNet/IP.
• The cabinet has a separate HMI.
• Local adjustment is restricted for operational reasons.
• The electrical panel is designed without individual keypads.
• A large number of drives are installed together.

This can result in a cleaner and more standardized control architecture.

---

32. Maintenance Considerations

Because the drive is air cooled and designed for high-power industrial service, maintenance should focus strongly on thermal and electrical conditions.

Regular inspection should include:

• Cooling fans
• Air passages
• Electrical terminals
• Power connections
• Grounding connections
• Motor cables
• Network cables
• Cabinet cleanliness
• Signs of overheating
• Fault history
• Warning history
• Abnormal vibration
• Fan noise

A clean cooling system is especially important for a 650 A Frame 8 drive.

Dust accumulation can reduce airflow and increase internal temperatures.

---

33. Installation Considerations

The drive’s approximately 623 kg weight means that handling should be planned before installation.

The electrical room should have suitable access for transportation.

The supporting structure should be checked for the actual equipment weight.

Adequate working space should also be provided around the drive.

The nominal dimensions of approximately 2102 × 606 × 600 mm should not be treated as the entire installation footprint.

Additional room may be necessary for:

• Power cable routing
• Motor cable routing
• Grounding
• Ventilation
• Service work
• Door operation
• Control wiring
• Network connections

---

34. Thermal Management

Thermal management is particularly important for a drive in this power class.

The installation should avoid placing the drive in a location where hot air is continuously recirculated.

Good cabinet design should provide a defined airflow path.

Potential problems include:

• High ambient temperature
• Blocked ventilation
• Dirty air filters
• Fan failure
• Poor cabinet design
• Insufficient separation between hot and cool airflow

These conditions can reduce the life of power electronics and other internal components.

---

35. Electrical Noise and Grounding

High-power variable frequency drives generate switching waveforms that can create electrical noise.

The installation should therefore pay attention to:

• Grounding
• Shielding
• Cable separation
• Motor cable routing
• Cabinet bonding
• Control cable routing
• Network cable routing
• Motor frame grounding

The CM jumper removed configuration should be considered as part of the complete grounding and EMC design rather than as an isolated parameter.

---

36. Why the 20G1ABC650AN0NNNNN Is a Strong Choice

The model offers a particularly useful combination of:

650 A current capacity

400 kW Low Duty

355 kW Normal Duty

315 kW Heavy Duty

400 VAC three-phase input

Frame 8 construction

Forced-air cooling

Embedded EtherNet/IP

AC input with precharge

EMC filtering

CM jumper removed

No local HIM

600 mm deep MCC-style construction

This combination makes the drive particularly suitable for large automated industrial systems.

38. Overall Evaluation

The Allen-Bradley 20G1ABC650AN0NNNNN is a substantial high-power drive intended for large industrial motor applications.

Its 650 A current class and 400 kW Low Duty rating make it particularly suitable for large variable-torque loads, while its 355 kW Normal Duty and 315 kW Heavy Duty ratings provide useful capacity for more demanding industrial machinery.

The embedded EtherNet/IP interface is a major benefit for automated facilities because the drive can be incorporated into a centralized control architecture.

The AN0 no-HIM configuration is particularly well suited to installations where local keypad operation is unnecessary and drive control is handled through a PLC, HMI, SCADA system, or other centralized control arrangement.

The 600 mm deep MCC-style Frame 8 construction provides a practical high-power installation format, while the forced-air cooling architecture is suitable for conventional industrial electrical rooms when adequate ventilation is provided.

The main points to pay attention to during selection are the 650 A current rating, 400/355/315 kW duty ratings, CM jumper removed configuration, lack of dynamic braking, no local HIM, cooling requirements, approximate 623 kg weight, and approximately 2102 × 606 × 600 mm physical size.

For large pumps, fans, blowers, conveyors, compressors, mixers, process machinery, and other high-power rotating equipment, the 20G1ABC650AN0NNNNN represents a strong high-capacity PowerFlex 755 configuration.

When replacing or comparing this model, the closest candidates are the 20G1ABC650JN0NNNNN, 20G1ABC650AN2NNNNN, 20G1ABC650AN4NNNNN, 20G1ABC567AN0NNNNN, and 20G1ABC750AN0NNNNN. The most important differences are generally the configuration generation, CM jumper arrangement, local HIM configuration, and available current/power capacity.
