---

6. Dynamic-Braking Configuration

The AA configuration of this model includes an internal dynamic-braking transistor.

This is one of the most important differences between 20G1ANE289AA0NNNNN and related AN configurations.

Braking Parameter	Specification
Model	20G1ANE289AA0NNNNN
Internal Dynamic-Braking Transistor	Yes
Dynamic-Braking Hardware	Integrated
Braking Application	High-Inertia Loads
Regenerative Energy Handling	Supports applicable braking arrangements

---

11. Product Introduction

The Allen-Bradley 20G1ANE289AA0NNNNN PowerFlex 755 AC Drive is a high-current variable frequency drive designed for large industrial motor-control applications.

With a 600 VAC three-phase rating and 289 A continuous output capability, it belongs to the large-drive category.

The drive is designed for applications where motor speed needs to be controlled rather than simply switching a motor on and off.

This provides greater flexibility in industrial systems where process requirements vary throughout the operating cycle.

The 300 HP normal-duty rating makes the drive suitable for very large pump, fan, blower, conveyor, and process-machine applications.

Its 250 HP heavy-duty rating provides a separate operating class for applications with more demanding load conditions.

The integrated dynamic-braking transistor is one of the most significant features of this exact configuration.

It provides additional flexibility for applications where the motor must decelerate quickly or where the mechanical load can return energy to the drive during deceleration.

The embedded EtherNet/IP interface also allows the drive to become part of a connected automation system.

---

12. Large Pump Applications

Large industrial pumps can benefit from variable-speed control.

A pump does not necessarily need to operate at full speed continuously.

Process requirements may change according to pressure, flow, tank level, production rate, or other conditions.

The drive can adjust motor speed according to the process requirement.

Typical applications include:

• Industrial water pumps
• Process circulation pumps
• Cooling-water systems
• Water-treatment systems
• Large transfer pumps
• Industrial utility pumps
• Irrigation systems
• Process pumping systems
• Large fluid-handling systems

The controlled acceleration and deceleration functions can also provide smoother mechanical operation.

For large pump systems, proper acceleration and deceleration can help reduce sudden hydraulic and mechanical changes.

---

13. Large Fan and Blower Applications

Large fans and blowers can require motors in the hundreds of horsepower range.

The 300 HP normal-duty rating makes this drive appropriate for substantial airflow systems.

Typical applications include:

• Industrial ventilation
• Large exhaust systems
• Dust collection
• Furnace ventilation
• Process-air systems
• Large cooling fans
• Industrial blowers
• Air-handling systems

Variable-speed control allows the fan speed to be adjusted to match airflow requirements.

This can provide greater flexibility than operating the motor continuously at full speed.

---

14. Conveyor Applications

The 20G1ANE289AA0NNNNN is particularly interesting for large conveyor systems because it includes an internal dynamic-braking transistor.

Large conveyors can contain considerable mechanical inertia.

When a heavily loaded conveyor is stopped, the rotating system can return energy toward the drive.

The dynamic-braking configuration provides a way to manage braking energy when the application is designed for it.

Typical applications include:

• Mining conveyors
• Aggregate conveyors
• Bulk-material handling
• Long belt conveyors
• Heavy-duty production conveyors
• Material-transfer systems
• Industrial logistics systems

The exact braking resistor and braking requirements must be selected according to the actual mechanical load.

---

15. Material-Handling Applications

Large material-handling equipment can require both high motor capacity and controlled braking.

The 289 A drive provides substantial current capacity while the internal dynamic-braking transistor adds flexibility for deceleration requirements.

Potential applications include:

• Bulk material systems
• Feed systems
• Heavy conveyors
• Transfer machinery
• Material-processing equipment
• Industrial lifting-related machinery
• Large rotating material-handling equipment

The application should be evaluated carefully if it involves vertical loads or other overhauling conditions.

---

16. Mixer and Agitator Applications

Large mixers can have significant starting torque requirements.

The load may change depending on the material being mixed, fill level, viscosity, and production stage.

Variable-frequency control allows the motor to operate at different speeds.

Typical applications include:

• Industrial mixers
• Large agitators
• Chemical processing
• Water treatment
• Slurry systems
• Material blending
• Industrial processing

The motor current and overload requirements should be checked carefully for high-torque mixing applications.

---

17. Process Machinery Applications

The drive can be used for a wide range of large process machinery.

Typical applications include:

• Production machinery
• Process equipment
• Large mechanical systems
• Industrial utility equipment
• Rotating process machines
• Large auxiliary machinery
• Manufacturing equipment

The embedded network capability can allow the drive to exchange information with the process-control system.

This is useful when motor speed needs to change according to production conditions.

---

18. Compressor and Heavy Rotating Equipment Applications

Large compressors and other rotating machines can require substantial motor current.

The drive’s 289 A capacity provides a high-power platform for applications where the motor needs controlled speed.

However, compressor applications require careful consideration of the compressor manufacturer’s motor requirements, load characteristics, acceleration time, and operating range.

The drive should therefore be selected based on the complete application rather than horsepower alone.

---

19. Main Product Advantages

High 289 A Output Capacity

The 289 A current rating gives the drive substantial motor-control capability.

It is suitable for large motors where smaller PowerFlex drives would not have enough current capacity.

---

The 250 HP heavy-duty rating provides a separate operating class for applications with higher load demands.

This is particularly useful for machinery with demanding acceleration or variable process loads.

---

Integrated Dynamic-Braking Transistor

The internal dynamic-braking transistor is a major advantage of the AA configuration.

It provides additional flexibility when the mechanical system produces regenerative energy during deceleration.

---

Embedded EtherNet/IP

The integrated communication capability allows the drive to communicate with an industrial automation system.

This can simplify centralized control and diagnostics.

---

EMC Filtering

The filtered configuration supports electrical-noise management in industrial installations.

---

---

25. Large Pump Advantages

For large pumps, variable-speed operation provides an important level of process flexibility.

A pump may need to deliver different flow rates at different times.

Instead of controlling the process entirely through mechanical throttling, the motor speed can be adjusted through the drive.

The 300 HP normal-duty capacity allows this model to be used with large pump motors.

The controlled acceleration function can also reduce sudden mechanical and hydraulic changes during starting.

For pump systems that do not require rapid regeneration, the internal dynamic-braking capability may not be heavily used, but it remains available as part of the drive configuration.

---

26. Large Fan and Blower Advantages

Fans and blowers can experience changing airflow requirements.

Variable-speed operation provides a direct method for adjusting airflow by changing motor speed.

---

27. Conveyor Advantages

The internal dynamic-braking transistor gives this model additional usefulness in conveyor applications.

A large conveyor can have considerable stored kinetic energy.

When the conveyor is commanded to stop, this energy can flow back toward the drive.

The dynamic-braking arrangement can help manage this energy when used with the appropriate braking components.

The result is a drive configuration that is well suited to applications where controlled deceleration is important.

---

28. High-Inertia Machinery

High-inertia equipment is one of the application areas where dynamic braking becomes particularly important.

Examples include:

• Large fans
• Large blowers
• Centrifugal equipment
• Large conveyors
• Flywheel-driven systems
• High-inertia process machinery
• Large rotating machinery

The internal braking transistor gives the drive greater flexibility for these applications than a similar configuration without the transistor.

The exact braking resistor and deceleration parameters still need to be selected according to the actual machine.

---

Typical areas include:

• Input power
• Motor current
• Motor parameters
• Acceleration settings
• Deceleration settings
• Braking parameters
• Motor cable
• Grounding
• Cooling
• Cabinet temperature
• Network communication
• Mechanical load
• Overload conditions

If the drive repeatedly enters an overload condition, the motor and mechanical load should be examined.

If the drive trips during deceleration, the braking system and deceleration settings should be investigated.

If communication is unstable, both the physical network and drive communication configuration should be checked.

---

34. Why the Exact Catalog Number Matters

The exact catalog number 20G1ANE289AA0NNNNN should be preserved in purchasing, maintenance, and replacement documentation.

40. Final Product Description

The Allen-Bradley 20G1ANE289AA0NNNNN PowerFlex 755 AC Drive is a high-capacity industrial variable frequency drive designed for large three-phase motor applications.

Its 600 VAC voltage class and 289 A continuous output rating place it in the high-power section of the PowerFlex 755 family.

The drive provides a 300 HP normal-duty rating and a 250 HP heavy-duty rating, making it suitable for substantial industrial motors and machinery.

The Frame 7 construction provides the mechanical platform required for this level of electrical capacity.

The approximate physical dimensions are 881.5 mm high, 430.0 mm wide, and 349.6 mm deep, with an approximate weight of 72.6–108.9 kg.

Because of its size and weight, installation should be planned carefully.

A suitable cabinet must provide adequate mounting strength, ventilation, cable space, and maintenance access.

The forced-air cooling system is designed to remove heat generated during operation.

Good airflow management is therefore an important part of the overall installation.

One of the most valuable features of this exact model is the internal dynamic-braking transistor.

This makes the drive particularly useful for applications in which the motor or mechanical load produces significant regenerative energy during deceleration.

Large conveyors, high-inertia fans, blowers, rotating machinery, and other heavy mechanical systems can benefit from this configuration when the appropriate braking arrangement is provided.

The drive also includes an EMC filter and uses the CM-jumper-removed configuration.

These details are important because they distinguish this model from other 289 A PowerFlex 755 configurations.

The embedded EtherNet/IP capability allows the drive to become part of a larger industrial automation architecture.

This means that the drive can exchange operating commands and information with a control system rather than operating as an isolated motor controller.

For large pumps, the drive can provide adjustable motor speed according to changing process requirements.

For large fans and blowers, it can provide variable airflow control.

For conveyors and material-handling systems, it can provide controlled acceleration and deceleration, with the internal dynamic-braking transistor providing additional braking capability.

For mixers and process machinery, adjustable motor speed can provide greater flexibility during different stages of production.

For large rotating equipment, the high current rating provides sufficient capacity for substantial motors when the motor nameplate requirements fall within the drive’s ratings.

The 300 HP normal-duty and 250 HP heavy-duty ratings should be considered together with the actual motor current.

Horsepower is an important selection parameter, but motor nameplate current, duty cycle, acceleration requirements, mechanical inertia, ambient temperature, cable installation, and braking requirements are equally important.

The complete catalog number 20G1ANE289AA0NNNNN should always be retained when purchasing or replacing the drive.

The difference between the AA and AN configurations, for example, is significant because the AA version includes an internal dynamic-braking transistor while the AN version does not.

Similarly, the J and A configurations identify different common-mode capacitor jumper arrangements.

Therefore, replacing the drive based only on voltage, horsepower, or current can result in a configuration mismatch.

Overall, the 20G1ANE289AA0NNNNN is a large-frame industrial AC drive designed for demanding motor-control applications.

Its combination of 289 A output capacity, 600 VAC operation, 300 HP normal-duty capability, 250 HP heavy-duty capability, Frame 7 construction, forced-air cooling, internal dynamic-braking transistor, EMC filtering, removed CM jumper, and embedded EtherNet/IP makes it well suited to large industrial motor systems.

It is particularly appropriate for applications where high motor capacity, controlled speed, industrial network integration, and dependable deceleration control are all important considerations.
