Allen-Bradley 20G1ABC567JN0NNNNN – PowerFlex 755 Air-Cooled AC Drive

The Allen-Bradley 20G1ABC567JN0NNNNN is a high-power PowerFlex 755 air-cooled AC drive designed for large industrial motor applications. It combines a 400 VAC three-phase input, 567 A current capacity, forced-air cooling, embedded EtherNet/IP communication, and a high-power Frame 8 construction.

This configuration provides 355 kW Light Duty, 315 kW Normal Duty, and 250 kW Heavy Duty ratings. It is therefore suitable for a wide range of large variable-speed applications, including conveyors, pumps, fans, blowers, compressors, mixers, material-handling systems, and large production machinery.

The JN0 configuration is especially notable because it is a no-HIM configuration. Instead of having a local handheld display mounted as part of the drive configuration, the drive is intended to work within a centralized control and automation architecture, or with a suitable external interface when local access is required.

The product is an active configuration and is the direct replacement configuration associated with the earlier 20G1ABC567AN0NNNNN model.

---

1. Basic Product Information

The dimensions and weight are intended as practical Frame 8 reference values. Actual shipping configuration, associated components, mounting arrangements, and installation hardware can affect the final dimensions and weight.

---

2. Brand and Series

The PowerFlex 755 series is intended for demanding industrial applications where motor control, communication, diagnostics, flexibility, and integration with automation systems are important.

Compared with smaller general-purpose drives, the PowerFlex 755 platform is aimed at larger machines and more sophisticated industrial systems.

The 20G1ABC567JN0NNNNN belongs to the high-current end of the air-cooled PowerFlex 755 range.

---

3. Detailed Technical Parameters

---

4. Electrical Rating

The most important electrical characteristic of the 20G1ABC567JN0NNNNN is its 567 A current capacity.

This places the model firmly in the high-power industrial-drive category.

The drive has three principal duty classifications:

The three ratings should be considered according to the actual motor current and load profile.

For example, a centrifugal fan and a heavy-duty conveyor may use motors with similar nominal power but have very different acceleration, overload, and torque requirements.

Therefore, final drive selection should be based on motor full-load current, overload requirements, acceleration time, load inertia, operating cycle, and application duty, rather than simply matching the motor nameplate kW.

---

5. 400 VAC Three-Phase Operation

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

This voltage class is widely used for industrial motors and machinery.

The three-phase input configuration makes the drive suitable for large motors used in:

• Manufacturing equipment.
• Pumps.
• Fans.
• Blowers.
• Compressors.
• Conveyors.
• Mixers.
• Process machinery.
• Material-handling systems.
• Large production lines.

The drive converts the incoming electrical power into controlled motor output so that motor speed can be adjusted according to the process requirement.

---

6. 567 A High-Current Capability

A 567 A drive is substantially larger than the drives normally used for small machinery.

This high current rating allows the drive to control large motors while maintaining the current capacity necessary for industrial operation.

The 567 A configuration is particularly useful where a 460 A or 540 A model may not provide enough capacity, but moving to a 650 A or 750 A model would result in unnecessary oversizing.

This makes the 567 A model an important middle point within the high-power Frame 8 range.

---

7. AC Input with Precharge

The 20G1ABC567JN0NNNNN uses an AC input with precharge.

A high-power AC drive contains a DC-link section that stores electrical energy.

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

The precharge arrangement manages this initial charging process and helps control the electrical stress associated with energizing the drive.

This configuration is intended for conventional AC-fed operation.

---

8. No DC Terminals

This model does not provide DC input terminals.

That makes it particularly straightforward for conventional applications in which each drive receives its own AC supply.

Applications involving a common DC bus, regenerative energy transfer, or specialized DC-link architectures require separate engineering evaluation.

For a conventional motor-drive installation, however, the AC input arrangement is generally straightforward.

---

9. Filtering and CM Jumper

The drive is specified with filtering and the CM jumper installed.

This configuration is important when designing the overall electrical installation.

Variable frequency drives generate high-frequency switching components during normal operation.

Proper EMC performance depends on more than the drive itself.

The complete installation should consider:

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

The CM jumper configuration should also be considered when designing the grounding and common-mode electrical arrangement.

---

10. Dynamic Braking

The 20G1ABC567JN0NNNNN is specified without internal dynamic braking.

For many applications, this is perfectly acceptable.

Large centrifugal pumps, fans, and many continuous-process machines do not necessarily require rapid deceleration.

However, braking requirements become more important when the driven machine has substantial rotational inertia.

Examples include:

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

If the application requires rapid stopping, the complete system should be evaluated for braking and regenerated energy management.

---

11. Blank / No HIM Configuration

The JN0 configuration does not include a local HIM.

This is one of the most important differences between this model and the JN2 configuration.

The no-HIM configuration is especially useful when the drive is installed as part of a centralized automation system.

For example:

PLC → EtherNet/IP → PowerFlex 755 → Motor

The operator may interact with the machine through a central HMI rather than directly through a drive-mounted interface.

This can provide a clean and consistent operator experience across a large production line.

---

12. Why the No-HIM Configuration Can Be an Advantage

A no-HIM configuration is not necessarily a stripped-down or inferior product.

It is often selected intentionally.

In a modern automated plant, the drive may be installed inside an electrical room or MCC lineup where operators do not need direct access to a local display.

The PLC and HMI can provide:

• Start and stop control.
• Speed reference.
• Motor current monitoring.
• Fault monitoring.
• Alarm monitoring.
• Drive status.
• Parameter management.
• Production information.

This can be especially useful when dozens or hundreds of drives are integrated into a centralized control architecture.

---

13. Product Introduction

The Allen-Bradley 20G1ABC567JN0NNNNN is a high-capacity PowerFlex 755 AC drive intended for industrial motor control.

Its 567 A rating, Frame 8 construction, and 400 VAC three-phase input make it suitable for large motors and substantial mechanical loads.

The drive combines high electrical capacity with embedded industrial networking.

The result is a drive that can be integrated into centralized automation systems while maintaining the motor-control functions expected from a high-performance industrial variable frequency drive.

The 600 mm deep MCC-style construction is intended for substantial industrial electrical installations rather than small standalone machine panels.

---

14. Typical Applications

14.1 Large Conveyor Systems

Large conveyors often require controlled acceleration and deceleration.

Directly starting a large motor can produce significant mechanical and electrical stress.

Using a variable frequency drive allows the motor to accelerate progressively.

This can help reduce stress on:

• Belts.
• Gearboxes.
• Couplings.
• Bearings.
• Rollers.
• Mechanical structures.

The 567 A capacity makes this configuration appropriate for large conveyor systems when the motor current falls within the drive’s rating.

---

15. Large Pumps

Large industrial pumps are another strong application.

A pump does not always need to operate at full speed.

Adjusting motor speed can allow pump output to better follow process demand.

Typical applications include:

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

The drive can also communicate operating information to the central control system.

---

16. Large Fans

Large fans can be excellent candidates for variable-speed control.

Instead of running continuously at a fixed speed, the drive can adjust the motor according to ventilation requirements.

Potential applications include:

• Industrial ventilation.
• Furnace ventilation.
• Cooling systems.
• Process-air systems.
• Dust extraction.
• Large air-handling systems.

For many fan applications, the Light Duty rating can be particularly relevant, although the actual motor and load profile must always be evaluated.

---

17. Industrial Blowers

Industrial blowers can require substantial motor power.

Variable-speed operation allows the blower to respond to changing process conditions.

The 20G1ABC567JN0NNNNN can be suitable for large blower systems where the motor current is within the appropriate duty rating.

Applications may include:

• Industrial air supply.
• Process ventilation.
• Combustion air.
• Dust collection.
• Material processing.
• Large exhaust systems.

---

18. Compressors

Large compressors can have demanding starting and operating requirements.

The drive can provide controlled acceleration rather than simply applying full power directly to the motor.

This can help reduce mechanical shock and provide better control of the compressor operating cycle.

However, compressor applications should always be evaluated carefully because compressor torque characteristics can vary considerably.

---

19. Mixers and Agitators

Large mixers and agitators often require controlled acceleration and substantial torque.

The Heavy Duty rating can become particularly important for applications with high starting torque or frequent acceleration.

Potential applications include:

• Process mixing.
• Industrial chemical processing.
• Water treatment.
• Material preparation.
• Production tanks.
• Industrial processing systems.

---

20. Material Handling

Large material-handling equipment can benefit from controlled speed and acceleration.

Typical equipment includes:

• Heavy conveyors.
• Feed systems.
• Rollers.
• Transfer systems.
• Bulk material systems.
• Industrial handling equipment.

The drive can provide a controlled speed profile while communicating status information to the central automation system.

---

21. Large Production Machinery

The PowerFlex 755 platform can also be applied to large production machinery.

In these applications, motor speed may need to be coordinated with other machines.

The embedded EtherNet/IP interface makes this type of integration practical.

A centralized controller can coordinate:

• Motor speed.
• Start/stop commands.
• Process sequences.
• Fault conditions.
• Production states.
• Interlocks.
• Machine status.

This makes the drive suitable for large automated production lines.

---

22. Main Product Advantages

22.1 High 567 A Current Rating

The biggest advantage is the high current capacity.

At 567 A, the drive is capable of handling large industrial motors and substantial mechanical loads.

---

22.2 355 kW Light Duty Capacity

The 355 kW Light Duty rating provides significant capacity for applications where overload requirements are relatively moderate.

This can be attractive for large fan and pump applications.

---

22.3 315 kW Normal Duty Capacity

The 315 kW Normal Duty rating is an important reference for general industrial applications.

It provides substantial continuous operating capacity for large motors.

---

22.4 250 kW Heavy Duty Capacity

The 250 kW Heavy Duty rating allows the drive to be considered for applications where higher torque and overload performance are required.

This is particularly relevant to conveyors, mixers, and certain material-handling machinery.

---

22.5 Embedded EtherNet/IP

The integrated communication capability is one of the strongest advantages for automated facilities.

The drive can become part of the plant-wide control architecture rather than operating as an isolated motor controller.

---

22.6 No-HIM Configuration

For centralized control systems, the absence of a local HIM can be an advantage.

It allows the machine interface to be standardized around a central HMI or control system.

This can reduce unnecessary local interfaces throughout a large electrical room.

---

22.7 Forced-Air Cooling

Forced-air cooling is appropriate for high-power electrical equipment.

It provides an effective way of removing heat generated by the power electronics.

---

22.8 Frame 8 Construction

Frame 8 provides a physical platform suitable for high-current operation.

This is appropriate for large industrial electrical installations.

---

22.9 Flexible Application Range

The same basic drive platform can be applied to many types of industrial loads.

This can simplify standardization across a production facility.

---

23. Mechanical Parameters

The approximate 623 kg weight is a major consideration when planning transportation and installation.

The drive should be handled using lifting and transportation equipment appropriate for its actual configuration.

The approximately 2102 mm height also needs to be considered when planning electrical-room clearances.

---

24. Environmental Characteristics

The environmental values should be considered together with actual installation conditions.

High ambient temperature, restricted airflow, dust, altitude, and cabinet arrangement can all influence the thermal performance of a high-power drive.

---

25. Communication and Automation

The embedded EtherNet/IP interface is particularly valuable in modern automation systems.

A typical architecture may look like:

Central Controller → EtherNet/IP Network → 20G1ABC567JN0NNNNN → Large Motor

The controller can exchange information such as:

• Start command.
• Stop command.
• Speed reference.
• Actual speed.
• Motor current.
• Drive status.
• Alarm status.
• Fault status.
• Operating information.

This provides a centralized method of controlling and monitoring the motor.

---

26. JN0 Versus JN2

If local operator access is not required, the JN0 configuration can be a very practical choice.

The choice between JN0 and JN2 is therefore largely influenced by the control and maintenance philosophy of the installation.

---

27. JN0 Versus the Earlier AN0

The JN0 configuration is also particularly relevant when replacing an older AN0 configuration.

The electrical ratings are closely aligned, but the CM jumper configuration differs.

Therefore, when replacing an older AN0 unit with a JN0 configuration, the installation’s grounding and common-mode requirements should be reviewed rather than assuming a completely identical electrical configuration.

---

28. Five Same-Series / Related Models

The following five models are useful when comparing the 567 A drive with other high-power PowerFlex 755 configurations.

These five configurations form a useful high-power comparison group.

The 460 A model is the lower-current option, while the 650 A and 750 A models provide progressively greater current capacity.

The 567 A model occupies a useful position between the 540 A and 650 A configurations.

---

29. Five Related Models With Local HIM

For applications where local operation and maintenance are important, the following AN2/JN2 configurations are useful comparisons.

These are particularly useful when the application requires direct access to drive parameters and diagnostics.

---

30. Five Popular Allen-Bradley Models

These models are good references when comparing different current capacities within the same high-power family.

---

31. 567 A Configuration Comparison

The 567 A family is particularly useful when selecting replacement equipment.

This comparison shows why the complete catalog number matters.

The current and power ratings can remain the same while the enclosure, local interface, and electrical configuration change.

For replacement applications, these details should be checked individually.

---

32. Application Suitability

---

33. Installation and Mechanical Planning

The 20G1ABC567JN0NNNNN is a substantial industrial drive.

The approximate dimensions of 2102 × 606 × 600 mm should be incorporated into the electrical-room layout.

The approximately 623 kg weight should also be considered during transportation and installation.

Important mechanical considerations include:

• Floor loading.
• Lifting access.
• Transportation path.
• Cabinet positioning.
• Cable entry.
• Ventilation.
• Maintenance access.
• Fan servicing.
• Electrical connection space.
• Clearance around the equipment.

A high-power drive should not be treated like a small wall-mounted VFD.

It requires proper mechanical and thermal planning.

---

34. Thermal Management

The drive uses forced-air cooling.

At this power level, thermal management is particularly important.

The installation should provide adequate airflow around the drive and avoid situations where hot exhaust air is recirculated into the cooling intake.

Important factors include:

• Ambient temperature.
• Airflow.
• Cabinet ventilation.
• Dust accumulation.
• Installation altitude.
• Air temperature around the equipment.
• Fan condition.
• Filter condition where applicable.

Maintaining suitable airflow can have a direct impact on the long-term reliability of high-power power electronics.

---

35. Control System Integration

A typical centralized installation could use the following arrangement:

PLC

↓

Industrial Ethernet Network

↓

20G1ABC567JN0NNNNN

↓

Large AC Motor

The PLC can control the drive while the HMI provides operators with a centralized interface.

This architecture is especially attractive for production facilities where multiple drives are installed in the same process.

Instead of maintaining individual operator displays on every drive, the plant can use a standardized central interface.

---

36. Maintenance Advantages

Although this configuration has no local HIM, it can still be very effective for maintenance when integrated properly.

The control system can provide centralized access to important operating information.

Typical information includes:

• Drive status.
• Motor speed.
• Motor current.
• Frequency.
• Fault status.
• Alarm status.
• Operating state.
• Communication status.

This allows maintenance teams to diagnose problems from a central HMI or control station.

For large installations, this can be more efficient than physically visiting every drive for routine monitoring.

---

37. Important Selection Considerations

Before selecting the 20G1ABC567JN0NNNNN for a particular motor, several factors should be checked.

Motor Current

The motor full-load current should be compared with the applicable drive rating.

Duty Cycle

The application should be classified as Light Duty, Normal Duty, or Heavy Duty based on actual operating requirements.

Starting Torque

Machines with high starting torque need additional attention.

Acceleration

Long acceleration times and short acceleration times can impose different demands on the drive.

Load Inertia

High-inertia machines require careful consideration of acceleration and deceleration.

Braking

Because the configuration has no internal dynamic braking, braking requirements should be reviewed.

Ambient Temperature

The installation environment can affect thermal performance.

Network Architecture

The control system should be compatible with the drive’s embedded EtherNet/IP communication.

Local Interface

Because this is a JN0 configuration, a local HIM is not included.

If technicians require direct local access, an appropriate interface strategy should be considered.

---

38. Key Advantages Summary

---

39. Recommended Model Selection by Current

This progression makes the PowerFlex 755 family easier to evaluate when the motor current is the primary selection parameter.

The correct choice should still be based on the actual motor nameplate current and application duty rather than selecting the next model simply because its nominal kW appears suitable.

---

40. Overall Evaluation

The Allen-Bradley 20G1ABC567JN0NNNNN is a high-capacity industrial AC drive designed for serious motor-control applications.

Its combination of 567 A, 355 kW Light Duty, 315 kW Normal Duty, and 250 kW Heavy Duty ratings gives it substantial flexibility across different industrial loads.

The PowerFlex 755 platform is particularly well suited to applications where motor control needs to be combined with industrial networking and centralized automation.

The integrated EtherNet/IP communication makes the drive suitable for PLC-based control architectures.

The JN0 no-HIM configuration is particularly attractive for centralized systems where operators normally interact with a plant HMI rather than directly with the drive.

The drive’s Frame 8, 600 mm deep MCC-style construction, approximately 2102 × 606 × 600 mm dimensions, and approximately 623 kg weight also make it clear that this is intended for large industrial installations.

Its strongest application areas include large conveyors, pumps, fans, blowers, compressors, mixers, material-handling systems, and large production machinery.

The main points requiring additional engineering attention are the absence of internal dynamic braking, the no-HIM configuration, thermal management, installation space, grounding, motor cable design, and the actual motor duty cycle.

---

41. Final Technical Summary

---

Conclusion

The Allen-Bradley 20G1ABC567JN0NNNNN is a high-power PowerFlex 755 air-cooled AC drive designed for large industrial motor applications.

Its 567 A current capacity and 355 kW / 315 kW / 250 kW Light Duty, Normal Duty, and Heavy Duty ratings give it enough capacity for a wide range of large industrial machinery.

The combination of 400 VAC three-phase input, Frame 8 construction, forced-air cooling, embedded EtherNet/IP, AC input with precharge, filtering, and 600 mm deep MCC-style construction makes it particularly suitable for centralized industrial automation systems.

The JN0 configuration has no local HIM, which can be a practical advantage in installations where drive operation and monitoring are handled through a central PLC and HMI.

For maintenance-oriented installations where technicians need direct access to the drive, the corresponding JN2 configuration with an Enhanced LCD Full Numeric HIM may be more appropriate.

From an application perspective, the 20G1ABC567JN0NNNNN is especially well suited to large conveyors, pumps, fans, blowers, compressors, mixers, material-handling equipment, and large production machinery.

Its approximately 2102 × 606 × 600 mm dimensions and approximately 623 kg weight should be included in the mechanical planning from the beginning of the project.

Overall, the 20G1ABC567JN0NNNNN can be considered a high-current, high-power, Frame 8 PowerFlex 755 drive optimized for centralized industrial motor control and networked automation, particularly where a local drive-mounted HIM is not required.
