Allen-Bradley 20G1AJC567AN0NNNNN PowerFlex 755 AC Drive

1. Product Overview

The Allen-Bradley 20G1AJC567AN0NNNNN is a high-power PowerFlex 755 AC Drive designed for large industrial motor-control systems.

It belongs to the PowerFlex 750-Series and uses an air-cooled, three-phase architecture intended for demanding industrial applications where high motor current, reliable variable-speed control, network communication, and protected enclosure construction are required.

This model is configured for the 380–400 VAC / 400 VAC three-phase class, with a rated output current of 567 A. It is a Frame 8 drive packaged in a Type 12 / IP54, 800 mm deep MCC-style enclosure.

The drive provides 355 kW Light Duty, 315 kW Normal Duty, and 250 kW Heavy Duty ratings. Its configuration includes embedded Ethernet/IP, AC input with precharge, no DC terminals, EMC filtering, a removed common-mode jumper, no dynamic braking, and a blank configuration without a local HIM. 

The 20G1AJC567AN0NNNNN is therefore intended for applications where a conventional compact VFD would be undersized, while the plant requires a large, centralized, industrial motor-control solution.

Typical applications include large pumps, fans, blowers, conveyors, water-treatment equipment, mining machinery, cement-plant equipment, process machinery, material-handling systems, and other high-power rotating equipment.

The published PowerFlex selection information identifies the 567 A model as a Frame 8 drive with 355 kW Light Duty, 315 kW Normal Duty, and 250 kW Heavy Duty ratings. The same selection data list 612 A / 673 A for Light Duty, 567 A / 624 A / 851 A for Normal Duty, and 472 A / 708 A / 851 A for Heavy Duty.

*The 800 mm depth is associated with the published MCC-style configuration. The overall width, height, and complete shipping weight should be confirmed against the exact mechanical drawing and final cabinet arrangement. The approximately 500–700 kg figure is a practical preliminary planning range for a large Frame 8 packaged assembly, not a certified shipping weight.

4. Product Configuration

The complete catalog number is:

20G1AJC567AN0NNNNN

This is not simply a 567 A frequency converter.

The catalog number identifies a particular combination of voltage class, current capacity, enclosure style, cooling method, communication arrangement, braking configuration, filtering, common-mode configuration, and operator-interface configuration.

For procurement and replacement work, the complete catalog number should be retained because another PowerFlex 755 with a similar current rating may have a different voltage, enclosure, braking, HIM, or filtering configuration.

5. 567 A High-Current Output

The defining characteristic of the 20G1AJC567AN0NNNNN is its 567 A output-current class.

This places the product in the high-power industrial-drive category.

A 567 A drive is intended for large motors and large mechanical systems rather than small machine-level applications.

The current rating provides sufficient capacity for substantial motor loads while also allowing the drive to accommodate application-specific duty requirements.

For final drive selection, motor full-load current remains more important than motor horsepower alone.

The motor nameplate, load torque, acceleration requirements, overload conditions, ambient temperature, altitude, and process duty should all be considered.

6. Light Duty, Normal Duty and Heavy Duty Ratings

The 20G1AJC567AN0NNNNN provides three principal duty classes.

Duty Class	Continuous Current	1-Minute Current	3-Second Current	Power Rating
Light Duty	612 A	673 A	—	355 kW
Normal Duty	567 A	624 A	851 A	315 kW
Heavy Duty	472 A	708 A	851 A	250 kW

These different ratings allow the same basic drive platform to be used for different types of mechanical loads.

A fan may have relatively modest overload requirements, while a conveyor or process machine can require substantially higher short-duration torque during acceleration.

The 567 A model therefore provides a useful combination of high continuous current and short-duration overload capability.

7. Light-Duty Operation

The Light Duty rating reaches 355 kW.

This makes the model attractive for large variable-torque applications where the motor operates primarily under relatively predictable load conditions.

Potential examples include:

• Large centrifugal fans
• Large centrifugal pumps
• Cooling-water pumps
• Industrial ventilation
• Large process blowers
• Circulation systems

For these applications, the 355 kW Light Duty rating can provide substantial capacity while maintaining variable-speed control.

8. Normal-Duty Operation

The Normal Duty rating is 315 kW at a continuous current rating of 567 A.

This is a useful rating for general industrial applications where the load can vary and some short-term overload capacity is required.

Typical applications include:

• General process machinery
• Conveyors
• Pumps
• Fans
• Blowers
• Material handling
• Production machinery

9. Heavy-Duty Operation

The Heavy Duty rating is 250 kW.

Heavy Duty operation is generally more appropriate for applications where higher torque or more frequent overload conditions are expected.

Examples may include:

• Heavy conveyors
• High-inertia machinery
• Certain crushers
• Material-handling equipment
• Heavy process machinery
• Applications with demanding acceleration requirements

The Heavy Duty rating should always be compared with the actual motor current and mechanical load profile before final selection.

10. 400 VAC Three-Phase Architecture

The drive belongs to the 380–400 VAC three-phase class.

This voltage range is commonly encountered in industrial electrical systems.

The three-phase configuration makes it suitable for large industrial motors where single-phase or low-power machine drives are not appropriate.

The 400 V class also allows large motor power to be delivered without moving into medium-voltage drive equipment for many applications.

11. Frame 8 Construction

The drive is a Frame 8 PowerFlex 755.

Frame size is important because it affects:

• Physical dimensions
• Cooling requirements
• Current capacity
• Installation space
• Maintenance access
• Cabinet configuration
• Transportation
• Weight
• Cable routing

Frame 8 is a large drive frame intended for high-power industrial applications.

It should therefore be treated as floor-standing electrical equipment rather than as a compact wall-mounted inverter.

12. Type 12 / IP54 Enclosure

The 20G1AJC567AN0NNNNN uses a Type 12 / IP54, 800 mm deep MCC-style configuration.

This enclosure provides a protected installation environment suitable for many industrial electrical rooms.

The Type 12 construction is particularly useful where protection from dust and common industrial contaminants is required.

The IP54 classification provides protection against dust ingress at a level appropriate for the intended enclosure configuration and protection against water splashing from applicable directions.

The exact installation environment should still be evaluated before installation.

13. 800 mm Deep MCC-Style Design

The 800 mm deep MCC-style enclosure is a significant physical characteristic.

This configuration provides room for the high-power electrical components and associated internal equipment.

It also makes the product suitable for integration into centralized motor-control lineups.

The installation should include sufficient space for:

• Cable routing
• Ventilation
• Door operation
• Inspection
• Maintenance
• Component replacement
• Electrical testing
• Service access

14. Forced-Air Cooling

The drive uses forced-air cooling.

At this power level, heat management is an important part of system design.

The cooling system requires adequate airflow through the equipment.

The electrical room should be designed to prevent excessive ambient temperature and hot-air recirculation.

Cooling performance can be affected by:

• Dust
• Blocked airflow
• High ambient temperature
• Fan degradation
• Restricted ventilation
• Improper cabinet arrangement

15. Embedded Ethernet/IP

The 20G1AJC567AN0NNNNN includes embedded Ethernet/IP.

This allows the drive to become part of a modern industrial automation network.

A typical control architecture can be represented as:

PLC / Controller

↓

Ethernet/IP Network

↓

PowerFlex 755

↓

567 A Drive

↓

Industrial Motor

The network can carry drive commands, speed references, status information, fault information, operating data, and other control information.

This is especially useful in facilities containing multiple large drives.

16. AC Input with Precharge

The drive uses AC input with precharge.

The precharge system manages the initial charging of the internal DC bus.

This is particularly important for high-power drives because the DC bus contains substantial energy-storage components.

Proper precharge operation reduces electrical stress during energization and provides a controlled startup sequence for the power-conversion system.

17. No DC Terminals

The specified configuration has no DC terminals.

This means that the drive should be treated as an AC-input packaged drive rather than as a configuration intended for external DC-bus connection.

For system integration, engineers should use the exact catalog configuration and installation documentation when determining whether a DC-bus architecture is required.

18. EMC Filtering

The 20G1AJC567AN0NNNNN is configured with EMC filtering.

Electromagnetic compatibility is particularly important in high-power variable-frequency-drive installations.

The drive switches electrical power at high frequency, and this can create electrical noise that may affect nearby instrumentation, control systems, encoders, communication equipment, or other electronic devices.

The filter is therefore useful as part of the overall EMC strategy.

However, installation practices remain important.

Motor-cable routing, shielding, grounding, bonding, cabinet construction, and separation of power and signal wiring should all be considered.

19. Common-Mode Jumper Removed

The catalog configuration specifies that the common-mode jumper is removed.

This is an important configuration detail and should not be changed casually.

The common-mode configuration can influence the grounding relationship of the drive’s internal filter network and can affect leakage current and EMC behavior.

The correct configuration depends on the electrical system and grounding arrangement.

Before changing this jumper configuration, the complete electrical installation should be reviewed.

20. No Dynamic Braking

The 20G1AJC567AN0NNNNN is configured with no dynamic braking.

This is appropriate for many variable-speed applications where the load does not require rapid regenerative deceleration.

For high-inertia loads, however, the deceleration requirements should be evaluated carefully.

If the application requires rapid stopping, the engineer may need to consider:

• Controlled deceleration
• Mechanical braking
• Regenerative solutions
• External braking arrangements
• Process-specific stopping strategies

21. Blank / No HIM Configuration

The AN0 configuration uses a Blank / No HIM arrangement.

This means the drive does not include a local standard operator interface as part of this catalog configuration.

This configuration is often suitable for centralized automation systems where the drive is controlled through:

• PLC
• Ethernet/IP
• Supervisory control
• Engineering software
• External operator interfaces

It can also reduce the need for local operator hardware where the electrical equipment is located in a controlled-access electrical room.

22. Product Applications

23.1 High Current Capacity

The 567 A output rating provides substantial motor-control capability.

This makes the product appropriate for large industrial motors and high-power mechanical systems.

23.2 355 kW Light-Duty Capability

The 355 kW Light Duty rating makes the model especially attractive for large variable-torque loads such as fans and pumps.

This provides a useful advantage when the process requires high power but does not require the same overload profile as a Heavy Duty application.

23.3 315 kW Normal-Duty Capability

The 315 kW Normal Duty rating provides a strong balance between motor power and overload capability for general industrial applications.

23.4 250 kW Heavy-Duty Capability

24. Dimensions and Weight

Physical size is an important consideration for this model.

Mechanical Parameter	Specification / Planning Reference
Model	20G1AJC567AN0NNNNN
Frame	Frame 8
Enclosure	Type 12 / IP54
MCC Style	800 mm Deep
Depth	Approximately 800 mm

Approx. Complete Weight	Approximately 500–700 kg class*
Installation	Floor-Standing
Cooling	Forced Air
Handling	Heavy-Equipment Handling
Maintenance	Front/service access required

The product’s published configuration establishes the 800 mm deep MCC-style construction. The overall dimensions and final shipping weight depend on the complete cabinet arrangement, accessories, shipping configuration, and mechanical implementation.

For preliminary plant-layout planning, approximately 600 mm width × 2000–2200 mm height × 800 mm depth and approximately 500–700 kg can be used as an engineering allowance.

These values should not replace the certified mechanical drawing when designing the final foundation, lifting system, transportation route, or MCC lineup.

25. Installation Considerations

The 20G1AJC567AN0NNNNN is large and heavy electrical equipment.

Installation planning should begin before the equipment arrives at the site.

Important factors include:

Electrical Room Space

The room must have sufficient space for the cabinet and service access.

Cable Entry

Adequate room should be reserved for incoming power and motor-cable routing.

Ventilation

Forced-air cooling requires sufficient airflow.

Floor Loading

The final equipment weight should be verified before installation.

Transportation

The equipment dimensions and weight should be checked against doors, elevators, access corridors, cranes, forklifts, and other transportation routes.

Maintenance

• Signs of overheating

27. Cooling System Maintenance

Cooling is one of the most important maintenance areas.

Dust and contamination can reduce airflow.

Reduced airflow can increase component temperature.

High operating temperature can shorten the life of power electronic components.

The cooling system should therefore be inspected according to the site’s maintenance schedule.

28. Motor Cable and EMC Considerations

The motor cable should be selected according to:

• Motor current
• Cable length
• Ambient temperature
• Installation method
• Voltage drop
• EMC requirements

31. Five Recommended Same-Series or Related Models

The following five models are closely related to the 20G1AJC567AN0NNNNN and are useful for comparison within the same high-power PowerFlex 755 family.

Model	Voltage	Current	LD Power	ND Power	HD Power	Frame	Enclosure
20G1AJC460AN0NNNNN	400 VAC	460 A	315 kW	250 kW	200 kW	8	Type 12 / IP54
20G1AJC540AN0NNNNN	400 VAC	540 A	315 kW	315 kW	250 kW	8	Type 12 / IP54
20G1AJC567AN0NNNNN	400 VAC	567 A	355 kW	315 kW	250 kW	8	Type 12 / IP54
20G1AJC650AN0NNNNN	400 VAC	650 A	400 kW	355 kW	315 kW	8	Type 12 / IP54
20G1AJC750AN0NNNNN	400 VAC	750 A	450 kW	400 kW	315 kW	8	Type 12 / IP54

These models provide a useful current-capacity progression around the 567 A configuration. The selection data show 460 A, 540 A, 567 A, 650 A and 750 A versions in the same general 380–400 VAC Frame 8 PowerFlex 755 range, with progressively higher power ratings as current capacity increases.

32. Comparison of the Five Related Models

Model	Current	LD	ND	HD	Recommended Use
20G1AJC460AN0NNNNN	460 A	315 kW	250 kW	200 kW	Lower-power Frame 8 applications
20G1AJC540AN0NNNNN	540 A	315 kW	315 kW	250 kW	General large industrial applications
20G1AJC567AN0NNNNN	567 A	355 kW	315 kW	250 kW	Higher Light Duty capacity
20G1AJC650AN0NNNNN	650 A	400 kW	355 kW	315 kW	Larger high-power motors
20G1AJC750AN0NNNNN	750 A	450 kW	400 kW	315 kW	Very large motor applications

The 567 A model occupies an interesting position in this group.

It provides more Light Duty capacity than the 540 A model while maintaining the same 315 kW Normal Duty and 250 kW Heavy Duty ratings.

This makes it particularly useful for large variable-torque applications where Light Duty capacity is the primary selection factor.

33. Recommended Model – 20G1AJC460AN0NNNNN

38. Five Popular Allen-Bradley Models

The following models provide a broader view of commonly used products across the same brand.

Model	Series	Voltage Class	Current / Power Class	Frame	Typical Application
25B-D030N114	PowerFlex 525	480 VAC class	30 A class	Compact	Pumps, fans, conveyors, machinery
25C-D030N114	PowerFlex 527	480 VAC class	30 A class	Compact	Networked machine automation

20G1AND302JA0NNNNN	PowerFlex 755	480 VAC	302 A	Frame 7	Large industrial motor control

These five models cover a much broader range than the 567 A Frame 8 drive.

The 25B and 25C models are aimed at smaller machine-level applications, while the PowerFlex 755 models are designed for substantially larger motors and industrial systems.

39. Application Comparison

Application	20G1AJC567AN0NNNNN Suitability
Large Centrifugal Pump	Excellent
Large Industrial Fan	Excellent
Large Blower	Excellent
Mining Conveyor	Excellent
Cement Conveyor	Excellent
Bulk Material Handling	Excellent
Water Treatment	Excellent
Wastewater Treatment	Excellent
Cooling-Water System	Excellent
Process Machinery	Excellent
Heavy Manufacturing	Excellent
Small Machine	Poor Fit
Small Pump	Poor Fit
Small Fan	Poor Fit

The 20G1AJC567AN0NNNNN provides the greatest value in applications where the motor current is genuinely high.

For smaller motors, a more compact PowerFlex drive would normally provide a more economical and space-efficient solution.

40. Product Selection Considerations

Before selecting this model for a new application, the following parameters should be checked:

Selection Parameter	Requirement
Motor Voltage	Confirm compatibility with 400 VAC-class drive
Motor Current	Must be within selected duty rating
Motor Power	Compare with LD / ND / HD ratings
Duty Cycle	Determine LD / ND / HD
Starting Torque	Check acceleration requirement
Load Inertia	Evaluate acceleration and deceleration
Braking	Confirm whether external braking is needed
Motor Cable Length	Check voltage and EMC effects
Ambient Temperature	Confirm operating range
Altitude	Check possible derating
Enclosure	Confirm Type 12 / IP54 requirement
Communication	Confirm Ethernet/IP requirement
HIM	AN0 configuration has no local HIM
Installation Depth	Allow for 800 mm MCC configuration
Weight	Verify final equipment weight
Service Space	Provide adequate maintenance clearance

The most important point is that the drive should be selected based on motor current and mechanical duty, not simply the motor’s nominal kW.

41. Mechanical Installation Planning

A large Frame 8 drive requires considerably more installation planning than a compact VFD.

The following should be considered before procurement:

Floor Space

The 800 mm deep enclosure requires sufficient floor depth and service clearance.

Door Access

The cabinet doors must be able to open fully enough for service and inspection.

Cable Routing

Incoming and outgoing cables require adequate space and bending radius.

Ventilation

The cooling-air path must remain unobstructed.

Lifting

The final shipping weight and lifting points should be confirmed before transportation.

Floor Loading

The final installed weight should be checked against the floor structure.

Maintenance

Service access should be incorporated into the original electrical-room layout.

42. Why the 567 A Model Is Attractive

The 567 A configuration is particularly useful because it sits between several important capacity levels.

Compared with the 540 A version, it provides greater Light Duty capability.

Compared with the 650 A version, it occupies a lower current and power class.

This makes it a useful choice when:

• Light Duty power is more important than Heavy Duty power.
• A 315 kW Normal Duty rating is sufficient.
• The application needs approximately 567 A continuous output.
• A Frame 8 MCC-style installation is preferred.
• Ethernet/IP integration is required.
• A local HIM is not required.

43. AN0 Versus JN0

For this catalog number, the distinction between AN0 and JN0 is important.

HIM	Blank / No HIM	Blank / No HIM
Lifecycle	Discontinued	Replacement / current configuration

The older AN0 model was discontinued on June 30, 2024, and the JN0 version is identified as its direct replacement.

Therefore, the AN0 catalog number is particularly relevant for installed-base identification, while the JN0 version is the more appropriate reference when looking for a current replacement configuration.

46. Final Product Assessment

The Allen-Bradley 20G1AJC567AN0NNNNN is a high-power PowerFlex 755 Frame 8 AC drive intended for large industrial motor-control applications.

Its most important characteristics are the 567 A output rating, 355 kW Light Duty rating, 315 kW Normal Duty rating, 250 kW Heavy Duty rating, 400 VAC three-phase architecture, Type 12/IP54 enclosure, 800 mm MCC-style depth, forced-air cooling, and embedded Ethernet/IP.

The model is especially well matched to large pumps, industrial fans, blowers, conveyors, mining systems, water and wastewater equipment, cement plants, process machinery, and large material-handling systems.

The AN0 configuration is important for existing installations because it identifies an older catalog configuration. The product has been discontinued, with 20G1AJC567JN0NNNNN identified as the direct replacement.

For an existing installation, the original AN0 catalog number should therefore be retained in maintenance records, spare-parts documentation, equipment lists, and replacement planning.

For new procurement, the replacement JN0 configuration should be evaluated instead.

From a capacity-selection perspective, the 567 A model is positioned between the 540 A and 650 A versions. It provides a particularly useful 355 kW Light Duty / 315 kW Normal Duty / 250 kW Heavy Duty combination.

This makes the model a strong choice for large industrial applications where high continuous current is required but the application does not justify moving to the next larger 650 A or 750 A Frame 8 configuration.

The overall product should be regarded as a large floor-standing industrial drive package, not a compact inverter.

The electrical room, cabinet lineup, cable system, ventilation, floor loading, transportation route, maintenance access, and lifting arrangements should all be considered before installation.

For exact mechanical engineering, the final dimensional drawing and certified equipment weight should always take priority over preliminary planning values.
