Allen-Bradley 20G1ABC567JN2NNNNN – PowerFlex 755 Air-Cooled AC Drive

The Allen-Bradley 20G1ABC567JN2NNNNN is a high-power PowerFlex 755 air-cooled AC drive designed for large industrial motors and demanding variable-speed applications. It combines a 400 VAC three-phase input, 567 A output current capacity, forced-air cooling, embedded EtherNet/IP communication, and a large Frame 8 construction.

This model provides three important application ratings: 355 kW Light Duty (LD), 315 kW Normal Duty (ND), and 250 kW Heavy Duty (HD). This makes it suitable for a broad range of industrial machinery, from large pumps and fans to conveyors, compressors, mixers, process equipment, and heavy material-handling systems.

The JN2 configuration includes an Enhanced LCD Full Numeric Handheld/Local HIM, which is a major practical advantage for commissioning and maintenance. The drive can therefore be integrated into a centralized automation system while still providing convenient local access for technicians.

The model uses a Type 1, IP20, 600 mm deep MCC-style enclosure, with AC input and precharge, no DC terminals, filtering, CM jumper installed, and no internal dynamic braking.

1. Product Basic Information

---

2. Brand and Product Series

The PowerFlex 755 series is designed for industrial applications where a basic variable frequency drive is not enough.

It is intended for systems that require a combination of high-power motor control, adjustable speed, network communication, diagnostics, flexible configuration, and integration with a larger automation system.

The 20G1ABC567JN2NNNNN represents one of the high-current Frame 8 configurations within this family.

---

3. Detailed Technical Parameters

---

4. Electrical Rating

The 567 A current rating is the key electrical characteristic of the 20G1ABC567JN2NNNNN.

This is a high-current drive intended for large industrial motors rather than small machine applications.

Its three primary power ratings are:

The duty rating is important because two motors with the same nominal power can place very different demands on a drive.

A large centrifugal fan, for example, normally has very different starting and overload characteristics from a heavy conveyor or mixer.

For that reason, the drive should be selected using the actual motor full-load current and application duty rather than simply matching the motor’s kW rating.

---

5. 400 VAC Three-Phase Input

The drive is designed for a 400 VAC, three-phase industrial power system.

This voltage class is commonly used for large industrial motors.

The three-phase input makes the drive suitable for applications such as:

• Large pumps.
• Large fans.
• Industrial blowers.
• Compressors.
• Conveyors.
• Rollers.
• Mixers.
• Agitators.
• Material-handling equipment.
• Large production machinery.

The drive controls the motor by regulating the electrical output according to the required speed and torque.

---

6. 567 A High-Current Capacity

The 567 A rating gives the drive substantial capacity for large motors.

This makes the model useful when a lower-current configuration is not sufficient, while a significantly larger drive would result in unnecessary oversizing.

Within the same high-power range, the 567 A configuration sits between the 540 A and 650 A classes.

This makes it a useful selection point for projects where the motor current is relatively close to the 567 A range.

---

7. Light Duty, Normal Duty and Heavy Duty

The three duty categories deserve particular attention.

Light Duty – 355 kW

The 355 kW Light Duty rating is well suited to loads that generally operate with relatively predictable torque characteristics and moderate overload requirements.

Typical examples include:

• Centrifugal fans.
• Large blowers.
• Certain pumps.
• Continuous process machinery.

Normal Duty – 315 kW

The 315 kW Normal Duty rating is appropriate as a general reference for continuous industrial operation.

It provides a strong balance between motor capacity and overload capability.

Heavy Duty – 250 kW

The 250 kW Heavy Duty rating is more appropriate for applications where the machine requires greater torque or more demanding overload performance.

Potential examples include:

• Conveyors.
• Mixers.
• Agitators.
• Material-handling equipment.
• High-torque process machinery.

---

8. AC Input with Precharge

The 20G1ABC567JN2NNNNN uses an AC input with precharge.

High-power drives contain a DC-link section that stores electrical energy.

When the drive is energized, the DC bus must be charged in a controlled manner.

The precharge system manages this initial charging process.

This is an important part of the drive’s high-power AC input architecture.

---

9. No DC Terminals

This configuration does not include DC input terminals.

It is therefore primarily intended for conventional AC-fed applications.

For systems involving common DC buses, regenerative energy sharing, or other specialized DC-link architectures, a separate system-level engineering evaluation is required.

For standard individual AC drive applications, the configuration is straightforward.

---

10. Filtering and CM Jumper Installed

The model uses a filtered configuration with the CM jumper installed.

This configuration is important when considering the overall grounding and EMC arrangement.

Large variable frequency drives generate high-frequency switching components as part of normal operation.

The complete installation should therefore take into account:

• Motor cable length.
• Cable construction.
• Shielding.
• Grounding.
• Cabinet design.
• Cable routing.
• Separation between power and control wiring.
• Motor characteristics.
• Installation environment.

The CM jumper configuration is also part of the drive’s electrical installation strategy and should be considered when designing the grounding arrangement.

---

11. Dynamic Braking

The 20G1ABC567JN2NNNNN is specified with no internal dynamic braking.

This is acceptable for many industrial applications.

For example, large centrifugal pumps and fans may not require aggressive deceleration.

However, applications with high rotational inertia need more attention.

Examples include:

• Large rollers.
• High-inertia conveyors.
• Centrifuges.
• Rapid-cycle machinery.
• High-speed rotating equipment.
• Certain heavy material-handling systems.

If the application requires rapid stopping, the braking requirements should be evaluated separately.

---

12. Enhanced LCD Full Numeric HIM

One of the most important features of the JN2 configuration is the Enhanced LCD Full Numeric Handheld/Local HIM.

HIM stands for Human Interface Module.

The local interface provides a direct connection between the technician and the drive.

It can be used for:

• Monitoring drive status.
• Viewing motor current.
• Viewing output frequency.
• Checking alarms.
• Checking faults.
• Reviewing parameters.
• Adjusting configuration settings.
• Commissioning the drive.
• Troubleshooting.
• Performing local operating functions where appropriately configured.

This is particularly useful for large industrial systems because maintenance personnel can work directly with the drive rather than depending entirely on a remote control station.

---

13. JN2 Configuration Advantages

The JN2 configuration provides two levels of interaction.

Centralized Control

PLC / HMI → EtherNet/IP → Drive

The drive participates in the plant automation system.

Local Maintenance

Technician → Enhanced LCD HIM → Drive

The technician can access the drive directly.

This combination is one of the most practical aspects of the JN2 configuration.

---

14. Product Introduction

The Allen-Bradley 20G1ABC567JN2NNNNN is a high-power industrial AC drive designed for large variable-speed motor applications.

It provides a 567 A current rating and three different duty classifications, allowing it to serve a wide range of industrial load types.

Its Frame 8 construction and 600 mm deep MCC-style configuration indicate that it is designed for substantial electrical installations.

The drive is air cooled using forced airflow and includes embedded EtherNet/IP communication.

The local Enhanced LCD Full Numeric HIM provides an additional level of convenience for commissioning and maintenance.

Together, these features make the drive suitable for large automated production systems where high motor power and practical maintenance access are both important.

---

15. Main Product Applications

15.1 Large Conveyor Systems

Large conveyors are one of the most common types of application for a high-current industrial drive.

A conveyor motor may need controlled acceleration to prevent:

• Belt shock.
• Mechanical impact.
• Gearbox stress.
• Coupling stress.
• Product movement problems.
• Excessive starting current.

Variable-speed operation also allows conveyor speed to be adjusted to production requirements.

The 567 A capacity provides the electrical capability required by many large conveyor motors.

---

16. Large Pumps

Large pumps can benefit significantly from variable-speed control.

Instead of operating continuously at a fixed speed, the drive can adjust motor speed to meet process demand.

Potential applications include:

• Industrial water circulation.
• Cooling-water systems.
• Process-fluid systems.
• Water treatment.
• Industrial pumping stations.
• Large circulation systems.

The drive can also provide operating information to the automation system, allowing pump operation to be monitored centrally.

• Material-processing systems.

The network capability can also allow blower operating conditions to be monitored through a central control system.

---

19. Compressors

Large compressors can require considerable motor power and controlled acceleration.

The drive allows the motor to be started and accelerated in a controlled manner rather than simply applying full-speed operation immediately.

This can help reduce mechanical stress.

Compressor applications should nevertheless be evaluated according to the actual compressor torque profile, motor current, starting conditions, and operating cycle.

---

20. Mixers and Agitators

Industrial mixers and agitators can require substantial starting torque.

The drive’s Heavy Duty rating may be particularly relevant for these applications.

Typical applications include:

• Process mixing.
• Material preparation.
• Water treatment.
• Industrial processing.
• Production tanks.
• Chemical-process equipment.

Variable-speed operation also allows the process speed to be adjusted according to production requirements.

---

21. Material Handling

The 567 A capacity makes the drive suitable for many large material-handling applications.

Examples include:

• Heavy conveyors.
• Feed systems.
• Rollers.
• Transfer systems.
• Bulk-material handling.
• Large processing lines.

Controlled acceleration and speed can help reduce mechanical stress and improve process control.

---

22. Large Production Machinery

The drive can be integrated into large production machines where motor speed needs to be coordinated with other equipment.

The embedded EtherNet/IP interface allows the drive to participate in centralized control.

For example:

Central Controller

↓

Industrial Network

↓

20G1ABC567JN2NNNNN

↓

Large Motor

The controller can manage speed commands, start/stop commands, alarms, faults, and operating status.

---

The 315 kW Normal Duty rating makes the drive suitable for a broad range of continuous industrial machinery.

It is a useful reference point for general-purpose high-power applications.

---

23.4 250 kW Heavy Duty Rating

The 250 kW Heavy Duty rating provides a useful option for machinery requiring higher torque and more demanding overload performance.

---

23.5 Integrated EtherNet/IP

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

This can simplify control architecture and provide centralized access to operating information.

---

23.6 Enhanced LCD Local HIM

The local HIM is especially useful for commissioning and maintenance.

Technicians can inspect the drive without relying completely on the central control system.

---

23.7 Forced-Air Cooling

It provides a practical method of removing heat from the drive’s power electronics.

---

23.8 Frame 8 High-Power Construction

Frame 8 provides the physical platform necessary for high-current industrial operation.

---

23.9 Wide Application Range

The same drive platform can be used across many types of industrial machinery.

This can help standardize drive technology across a production facility.

---

24. Mechanical Parameters

The approximately 623 kg weight should be considered during transportation, lifting, floor-loading calculations, and installation planning.

The approximately 2102 mm height should also be considered when determining electrical-room clearances.

---

25. Technical Parameters at a Glance

---

26. JN2 Versus JN0

The most obvious comparison is between the JN2 and JN0 versions.

The main difference is the operator interface.

The JN2 version is better suited to applications where local commissioning and maintenance access are important.

The JN0 version is attractive when the entire system is controlled centrally.

---

27. JN2 Versus Older AN2 Configuration

The JN2 version is also closely related to the earlier AN2 configuration.

The two models have very similar fundamental power ratings.

The electrical configuration differs, particularly with respect to the CM jumper.

This distinction should be considered carefully during replacement planning.

---

28. Five Same-Series or Related Models

The following models are useful for comparing current and power capacity within the same PowerFlex 755 high-power range.

These five configurations form a useful comparison range.

The 460 A version is suitable for lower-current applications, while the 650 A and 750 A versions provide greater current capacity for larger motors.

The 567 A configuration provides a useful balance between electrical capacity and physical Frame 8 construction.

---

29. Five Related No-HIM Models

For applications using centralized control, these no-HIM versions are useful alternatives.

These are especially relevant when the operator interface is located elsewhere in the control system.

---

30. Five Popular Allen-Bradley Models

These models are useful reference points when comparing high-power drive capacity within the same brand and product family.

---

31. Five 567 A Related Configurations

For replacement and engineering comparisons, the following 567 A configurations are particularly useful.

This comparison shows how different catalog configurations can have identical basic current and power ratings while differing in operator interface and electrical configuration.

That is why the complete catalog number is important when selecting replacement equipment.

---

32. Application Suitability

---

33. Installation Considerations

Because this is a Frame 8, 567 A drive, installation planning should begin well before the equipment arrives.

The approximately 2102 mm height should be considered when planning electrical-room clearances.

The approximately 606 mm width and 600 mm depth should be included in cabinet and MCC layout calculations.

The approximately 623 kg weight is especially important.

Transportation and installation require suitable lifting and handling equipment.

The floor structure should also be checked to ensure that it can safely support the equipment.

---

34. Thermal Management

The drive uses forced-air cooling.

At 567 A, the drive can generate substantial heat during operation.

The installation therefore needs appropriate ventilation.

Important considerations include:

• Ambient temperature.
• Airflow.
• Cabinet ventilation.
• Heat dissipation.
• Dust accumulation.
• Fan condition.
• Installation altitude.
• Hot-air recirculation.

Maintaining proper airflow is essential for reliable long-term operation.

---

35. Communication and Control Architecture

A typical application can use the following architecture:

Central PLC

The electrical capacity of the two configurations is essentially in the same class, but their operator-interface arrangements are different.

---

39. Main Advantages Summary

---

40. Selection Guide

The 567 A configuration is particularly attractive when the motor current is near this range and the application benefits from a high-power Frame 8 drive with a local HIM.

---

41. Important Engineering Considerations

The 20G1ABC567JN2NNNNN should be selected based on the complete motor and application requirements.

Motor Full-Load Current

The motor nameplate current is one of the most important selection parameters.

Duty Cycle

Determine whether the application should be evaluated as Light Duty, Normal Duty, or Heavy Duty.

Starting Torque

High-starting-torque machinery requires careful evaluation.

Acceleration Time

Short acceleration times can require significantly more drive capacity than slow-starting applications.

Load Inertia

High-inertia loads may require additional braking consideration.

Braking

The drive has no internal dynamic braking in this configuration.

Cooling

Forced-air cooling requires appropriate ventilation.

Installation Space

The Frame 8 physical dimensions need to be considered during cabinet planning.

Weight

The approximately 623 kg weight requires suitable transportation and lifting arrangements.

The JN2 includes an Enhanced LCD Full Numeric HIM, making local commissioning and maintenance easier.

---

42. Overall Product Evaluation

The Allen-Bradley 20G1ABC567JN2NNNNN is a high-power industrial AC drive intended for large motor applications where both electrical capacity and practical control functionality are important.

Its 567 A rating gives it substantial current capacity.

Its 355 kW Light Duty, 315 kW Normal Duty, and 250 kW Heavy Duty ratings provide flexibility for different load characteristics.

The PowerFlex 755 platform makes the drive suitable for large automated systems that require network communication and advanced motor-control functions.

The embedded EtherNet/IP capability allows the drive to integrate into a centralized automation architecture.

At the same time, the Enhanced LCD Full Numeric HIM provides technicians with direct access to the drive.

This combination is particularly useful in large factories where normal machine operation is centralized but maintenance still requires local access.

The Frame 8 construction, approximately 2102 × 606 × 600 mm dimensions, and approximately 623 kg weight mean that the drive should be treated as a substantial industrial installation.

Mechanical handling, floor loading, ventilation, cable routing, and maintenance access should all be considered during system design.

The absence of internal dynamic braking is another important consideration.

For fans, pumps, blowers, and many continuous-process applications, this may not be an issue.

For high-inertia machinery requiring rapid deceleration, braking requirements should be reviewed separately.
