Allen-Bradley 20G1AJC567JN4NNNNN PowerFlex 755 AC Drive

1. Product Overview

The Allen-Bradley 20G1AJC567JN4NNNNN is a high-power PowerFlex 755 AC Drive designed for large industrial motor-control applications where high output current, stable variable-speed operation, industrial networking, enclosed construction, and reliable process control are required.

This model belongs to the PowerFlex 755 series within the PowerFlex 750-Series family.

The 20G1AJC567JN4NNNNN is a Frame 8, air-cooled, packaged AC drive configured for 400 VAC three-phase power. It has a rated output current of 567 A, with power ratings of approximately 355 kW for Light Duty, 315 kW for Normal Duty, and 250 kW for Heavy Duty.

The drive uses an 800 mm deep MCC-style enclosure with Type 12 / IP54 protection. It is designed as a floor-standing industrial drive package rather than a compact wall-mounted variable-frequency drive.

The model incorporates embedded EtherNet/IP, making it suitable for integration into networked industrial automation systems.

It also includes an Enhanced LCD Full Numeric HIM with an IP66 / NEMA Type 4X/12 configuration. This is one of the key differences between the JN4 and JN0 versions of the same 567 A drive.

The power section uses forced-air cooling, while the input configuration is AC input with precharge and no external DC terminals.

The drive is also configured with EMC filtering, a CM jumper installed in the preferred configuration, and no dynamic braking.

For large industrial equipment, this combination provides a practical balance of high current capacity, enclosed construction, local operator access, and network-based control.

4. Product Identification

The catalog number 20G1AJC567JN4NNNNN contains a large amount of configuration information.

The important practical characteristics are:

• PowerFlex 755 family.
• Packaged AC drive.
• 400 VAC class.
• 567 A current class.
• Frame 8.
• 800 mm deep MCC-style construction.
• Type 12 / IP54 enclosure.
• Forced-air cooling.
• Embedded EtherNet/IP.
• AC input with precharge.
• No external DC terminals.
• Filtered configuration.
• CM jumper installed.
• No dynamic braking.
• Enhanced LCD Full Numeric HIM.

The result is a large industrial drive package intended for installation in a dedicated electrical or MCC environment rather than inside a small machine enclosure.

5. Power Rating

The 20G1AJC567JN4NNNNN provides three principal duty classifications.

Duty Classification	Continuous Current Class	Power Rating
Light Duty	Approximately 612 A	355 kW
Normal Duty	567 A	315 kW
Heavy Duty	Approximately 472 A	250 kW

The 315 kW Normal-Duty rating is generally the most important figure when evaluating the drive for a continuous industrial motor application.

The 355 kW Light-Duty rating is applicable to applications with a more favorable overload profile.

The 250 kW Heavy-Duty rating reflects the reduced continuous-current capability associated with applications requiring greater overload performance.

This distinction is important when selecting a drive for conveyors, pumps, fans, blowers, mixers, and other mechanical loads.

6. Normal-Duty Operation

At approximately 567 A, the drive is capable of controlling a substantial industrial motor.

Normal-duty operation is generally relevant to applications where the motor runs at a relatively high continuous load but does not require the same overload capability expected from a heavy-duty constant-torque application.

Typical examples include:

• Large centrifugal pumps.
• Large fans.
• Blowers.
• Cooling systems.
• Water-treatment equipment.
• Process circulation systems.
• Large conveyors with moderate overload requirements.

7. Heavy-Duty Operation

For applications involving heavier mechanical loading, the drive’s Heavy-Duty rating is approximately 250 kW.

Heavy-duty selection is particularly important when the motor must withstand frequent acceleration, high starting torque, or temporary overload conditions.

Examples include:

• High-inertia conveyors.
• Material-handling systems.
• Mixers.
• Certain process machines.
• Machinery with frequent acceleration.
• Machines with substantial torque requirements.

A drive should always be selected according to actual motor current and load profile rather than simply matching the motor’s nominal kW rating.

8. 400 VAC Three-Phase Power

The 20G1AJC567JN4NNNNN is designed for a 400 VAC three-phase system.

This voltage class is widely used in industrial facilities.

The three-phase architecture makes the drive suitable for large induction motors and other compatible three-phase AC motor systems.

Before installation, the actual supply voltage should be checked against the motor and drive requirements.

The incoming electrical system should also be evaluated for:

• Short-circuit capacity.
• Grounding method.
• Protective devices.
• Disconnect equipment.
• Cable sizing.
• Harmonic conditions.
• Electrical isolation.
• Local installation regulations.

9. AC Input with Precharge

The drive uses an AC input with precharge.

Precharge is especially important for a large Frame 8 drive because of the substantial energy-storage components inside the DC bus.

When power is first applied, the DC-link capacitors need to charge in a controlled manner.

The precharge circuit limits the initial charging current and establishes the DC bus before normal power conversion begins.

For a large industrial installation, the input arrangement should be coordinated with the upstream switchgear and protection system.

10. No External DC Terminals

The catalog configuration specifies no external DC terminals.

This means the drive is primarily configured for conventional AC-input operation rather than for a system requiring an externally accessible DC bus.

This characteristic should be considered during system design.

If an application requires:

• Common DC bus operation.
• Regenerative power handling.
• Energy storage.
• DC-link interconnection.
• Specialized braking architecture.

then the complete drive configuration should be reviewed to ensure that the selected architecture supports those requirements.

11. Frame 8 Construction

Frame 8 places the 20G1AJC567JN4NNNNN in the large-drive category.

This is not a small machine-level VFD.

The equipment is physically substantial and normally requires:

• Floor mounting.
• Dedicated electrical-room space.
• Proper lifting equipment.
• Adequate front access.
• Appropriate cable-entry space.
• Cooling airflow.
• Service clearance.
• Suitable floor loading.

The Frame 8 architecture is designed to accommodate the power electronics, cooling equipment, converter and inverter components, control electronics, bus structures, protective components, and associated wiring required for a drive in this current class.

12. Type 12 / IP54 Enclosure

The drive uses a Type 12 / IP54 800 mm deep MCC-style enclosure.

This construction provides a substantially more protected installation than an open-frame drive.

It is appropriate for many industrial electrical rooms and production environments where dust and general industrial contamination may be present.

The enclosure should nevertheless be installed in an environment that remains within the specified operating conditions.

Particular attention should be paid to:

• Dust.
• Moisture.
• Corrosive gases.
• Ambient temperature.
• Airflow.
• Condensation.
• Cleaning chemicals.
• Salt or corrosive atmospheres.

13. Forced-Air Cooling

The drive uses forced-air cooling.

At this power level, thermal management is critical.

The cooling system removes heat generated by:

• Power semiconductors.
• Switching devices.
• DC bus components.
• Conductors.
• Control electronics.
• Converter components.
• Inverter components.

For this reason, the electrical room should provide suitable ventilation.

Cooling filters and air passages should also be maintained.

A dirty or restricted airflow path can increase internal temperatures and accelerate component aging.

14. Embedded EtherNet/IP

The embedded EtherNet/IP function is one of the most useful features for modern industrial installations.

The drive can be integrated into an Ethernet-based automation network for functions such as:

• Start/stop commands.
• Speed references.
• Frequency references.
• Drive status.
• Fault information.
• Alarm information.
• Actual speed feedback.
• Current monitoring.
• Parameter access.
• Diagnostic information.

This allows the drive to become an active component of the plant automation system.

15. Industrial Automation Integration

In a typical automated system, the drive may communicate with a PLC or other controller.

For example, a PLC can issue a speed command to a pump drive.

The drive can then return:

• Actual speed.
• Drive status.
• Current.
• Fault state.
• Alarm information.

The control system can use this information to adjust valves, coordinate other motors, maintain process pressure, or respond to abnormal operating conditions.

This type of architecture is especially useful when multiple PowerFlex drives are operating together.

16. Enhanced LCD Full Numeric HIM

The JN4 configuration includes an Enhanced LCD Full Numeric Human Interface Module.

This is one of the defining differences between the JN4 and JN0 versions.

The HIM provides local access to the drive.

Depending on the control configuration, it can be used for:

• Parameter setup.
• Status monitoring.
• Fault review.
• Alarm review.
• Local diagnostics.
• Commissioning.
• Maintenance.
• Troubleshooting.

The enhanced LCD interface is particularly useful during startup and service because technicians can work directly at the drive rather than relying exclusively on a remote control workstation.

17. IP66 / NEMA Type 4X/12 HIM

The HIM is specified with IP66 / NEMA Type 4X/12 protection.

This is useful in industrial installations where the operator interface is exposed to a more demanding environment than ordinary office equipment.

The enhanced local interface provides a convenient maintenance point while the main drive remains installed inside its large MCC-style enclosure.

18. No Dynamic Braking

The 20G1AJC567JN4NNNNN is configured with no dynamic braking.

This should be considered carefully during application engineering.

When a large motor decelerates, the rotating motor and load can return energy to the drive.

If the mechanical system has high inertia or requires rapid stopping, the DC bus voltage can rise during regeneration.

The application should therefore be evaluated for:

• Motor inertia.
• Load inertia.
• Deceleration time.
• Stop frequency.
• Emergency-stop requirements.
• Regenerative energy.
• Conveyor characteristics.
• Fan and pump behavior.

If braking energy must be dissipated or returned to the electrical system, an appropriate braking or regenerative solution should be considered.

19. EMC Filtering

The model is configured as a filtered drive.

Variable-frequency drives use high-frequency switching devices.

This switching can create conducted and radiated electrical noise.

The integrated filtering arrangement helps reduce unwanted electrical interference.

A complete EMC design should also consider:

• Motor cable length.
• Cable shielding.
• Grounding.
• Cable routing.
• Control-cable separation.
• Cabinet bonding.
• Network cable routing.
• Motor installation.

The drive’s EMC filter should therefore be regarded as part of a complete installation strategy rather than as a substitute for proper wiring practices.

20. CM Jumper Installed

The configuration specifies CM jumper installed, preferred.

The common-mode configuration affects the drive’s electrical relationship to ground and its EMC characteristics.

The correct configuration depends on the actual electrical system.

For replacement installations, engineers should inspect the existing equipment and confirm the grounding arrangement before changing the CM configuration.

21. Main Applications

21.8 Process Industries

The drive can also be applied to:

• Mixers.
• Agitators.
• Process pumps.
• Fans.
• Blowers.
• Conveyors.
• Large material-handling systems.

The correct selection depends on the motor’s current and the mechanical characteristics of the process.

22. Product Advantages

This is particularly valuable during commissioning and troubleshooting.

22.7 Flexible Duty Ratings

The LD, ND, and HD ratings allow the drive to be matched to different mechanical-load characteristics.

22.8 Forced-Air Cooling

The forced-air design supports high-power operation while providing a structured thermal-management system.

22.9 Integrated EMC Filtering

The filtered configuration helps support EMC performance in industrial installations.

22.10 Suitable for Large Industrial Equipment

The overall architecture is well suited to equipment that requires a high-power drive rather than a compact machine-level VFD.

23. Dimensions and Weight

Approx. Width	600 mm class
Approx. Height	2000–2200 mm class
Approx. Depth	800 mm
Approx. Weight	500–700 kg
Installation	Floor Standing
Cooling	Forced Air

The 500–700 kg value should be considered a planning range for a complete Frame 8 packaged installation.

It should not be treated as a certified shipping weight.

Before ordering transportation or lifting equipment, the final configured equipment weight should be confirmed.

24. Installation Considerations

The 20G1AJC567JN4NNNNN is a large electrical assembly and requires appropriate installation planning.

Important considerations include:

Floor Loading

The equipment can weigh several hundred kilograms.

The supporting floor or foundation should be capable of carrying the complete installed load.

Third, embedded EtherNet/IP makes the drive easy to incorporate into networked automation architectures.

Fourth, the Enhanced LCD Full Numeric HIM provides a practical local interface for commissioning and service.

Fifth, the drive’s multiple duty classifications allow engineers to evaluate the motor and mechanical load more precisely.

Finally, the PowerFlex 755 architecture provides a broad platform for large industrial motor-control applications.

35. Maintenance Advantages

The local HIM is particularly useful for maintenance.

When a large motor stops unexpectedly, technicians can inspect drive information at the equipment.

This can help determine whether the issue is related to:

• Overcurrent.
• Overload.
• Motor conditions.
• Network commands.
• Control parameters.
• Input power.
• Drive status.
• Communication.
• Acceleration.
• Deceleration.

A clear local interface can shorten troubleshooting time and reduce the need to connect an external computer for every basic service operation.

36. Recommended Application Architecture

For a large pump or fan system, a typical architecture can include:

Main Power System → PowerFlex 755 Drive → Three-Phase Motor → Mechanical Load

The drive can communicate with a PLC through embedded EtherNet/IP.

The PLC can receive process signals from:

• Pressure transmitters.
• Flow meters.
• Level sensors.
• Temperature sensors.
• Vibration monitoring.

The controller can then adjust the drive’s speed reference according to process requirements.

This architecture is particularly useful in water treatment, process plants, HVAC, mining, and material-handling systems.

38. Overall Product Assessment

The Allen-Bradley 20G1AJC567JN4NNNNN is a high-power PowerFlex 755 AC drive designed for large industrial motor-control systems.

Its combination of 567 A output current, 355 kW Light-Duty capability, 315 kW Normal-Duty capability, 250 kW Heavy-Duty capability, 400 VAC three-phase input, Frame 8 construction, forced-air cooling, Type 12/IP54 protection, 800 mm MCC-style enclosure, embedded EtherNet/IP, EMC filtering, and Enhanced LCD Full Numeric HIM makes it particularly suitable for demanding industrial installations.

The Enhanced LCD Full Numeric HIM is a major practical advantage of the JN4 configuration.

For facilities where technicians need to operate and diagnose the drive locally, this feature can be considerably more convenient than a no-HIM configuration.

The embedded EtherNet/IP interface makes the drive suitable for modern networked automation systems.

Large pumps, fans, blowers, conveyors, water-treatment equipment, wastewater systems, mining equipment, cement plants, material-handling systems, and process machinery are all appropriate application areas.

The 800 mm deep MCC-style cabinet also makes the drive suitable for centralized electrical-room installations where a floor-standing high-power drive is preferred.

The drive’s no-dynamic-braking configuration should be considered carefully for high-inertia or rapid-stop applications.

If the mechanical load produces significant regenerative energy, an appropriate braking or regenerative solution should be evaluated separately.

The approximate 600 mm-class width, 2000–2200 mm-class height, 800 mm depth, and 500–700 kg planning weight show the physical scale of the equipment.

These values are suitable for preliminary equipment-room planning, but final mechanical dimensions and weight should always be confirmed against the exact configured equipment drawing.

For direct comparison, the most relevant same-series models are 20G1AJC460JN4NNNNN, 20G1AJC540JN4NNNNN, 20G1AJC567JN4NNNNN, 20G1AJC650JN4NNNNN, and 20G1AJC750JN4NNNNN.

These models provide a useful current and power range around the requested 567 A configuration.

Overall, the 20G1AJC567JN4NNNNN can be described as a large-frame, high-current, enclosed, network-capable industrial AC drive with an enhanced local operator interface, intended for demanding 400 VAC motor-control applications where high power, reliable speed regulation, industrial networking, and local service access are important.
