1. Basic Product Information

Note: The dimensions and weight above are practical approximate reference values for the Frame 8 / 600 mm MCC-style configuration. Final shipping dimensions, mounting details, and actual installed weight can vary slightly according to the exact enclosure, accessories, options, and packaging arrangement.

---

2. Product Model Interpretation

The catalog number 20G1ABC567JN4NNNNN contains configuration information that helps identify the drive’s electrical and mechanical characteristics.

The important part of the model is the combination of 567, JN, and 4.

567 — High-Current Rating

The 567 portion identifies the drive’s high-current class. This is a substantially larger drive than many conventional PowerFlex units and is intended for large industrial motors.

The 567 A class provides considerable current capacity for applications involving large pumps, fans, compressors, conveyors, processing equipment, large mixers, and other heavy industrial machinery.

JN — Current Configuration Generation

The JN configuration represents the later/current configuration style within this PowerFlex 755 catalog family. It includes the installed CM jumper configuration and the modernized product configuration associated with the current version of this drive family.

4 — Enhanced Operator Interface Configuration

The 4 configuration identifies the version equipped with the Enhanced LCD Full Numeric HIM in a higher-protection, door-mounted style.

This is particularly useful when operators need to access drive information, parameters, alarms, status information, and commissioning functions without opening the main electrical enclosure.

---

3. Product Series

The 20G1ABC567JN4NNNNN belongs to the:

Allen-Bradley PowerFlex 755 Series

The PowerFlex 755 family is intended for higher-performance industrial motor control rather than simple fixed-speed motor starting.

It is particularly suitable for large motors where the application requires adjustable speed, controlled acceleration and deceleration, torque management, process control, diagnostics, and industrial communication.

The PowerFlex 755 architecture is also suitable for applications where the drive needs to work as part of a larger automation system rather than operating as an isolated standalone inverter.

---

4. Detailed Electrical Parameters

---

5. Low Duty, Normal Duty and Heavy Duty Ratings

One of the most important characteristics of this drive is that it has multiple application-dependent power ratings.

These ratings should not simply be interpreted as three interchangeable motor sizes.

The correct rating depends on the load profile, overload requirement, acceleration characteristics, motor current, operating speed range, ambient conditions, and application duty cycle.

For example, a pump or fan with a relatively smooth variable-torque load may be able to use the higher Low Duty rating.

A conveyor with frequent acceleration, substantial starting torque, or changing mechanical loads may need to be evaluated against the Normal Duty or Heavy Duty rating instead.

For applications with high breakaway torque or repeated overload conditions, the Heavy Duty rating is particularly important.

---

6. 400 VAC Three-Phase Input

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

This makes it suitable for many international industrial installations where 380–400 VAC-class three-phase distribution systems are used.

The three-phase architecture provides a practical solution for large motor applications because it distributes input power across the three input phases and supports high-power motor operation without requiring an unusually high single-phase current infrastructure.

For a large industrial system, the upstream electrical distribution should be designed around the complete installation rather than the drive current alone.

This includes:

• Incoming supply capacity
• Short-circuit current considerations
• Upstream disconnect equipment
• Semiconductor protection requirements
• Grounding
• Cable sizing
• Motor cable length
• Electromagnetic compatibility
• Cabinet ventilation
• Ambient temperature
• Harmonic considerations

---

7. 567 A High-Current Capability

The 567 A current class is one of the defining characteristics of the 20G1ABC567JN4NNNNN.

A drive at this current level is intended for substantial industrial equipment.

The large current rating makes it suitable for motors that would be beyond the practical range of many smaller variable frequency drives.

Typical examples include:

• Large process pumps
• Large cooling-water pumps
• Industrial fans
• Large air-handling blowers
• Belt conveyors
• Bulk material conveyors
• Crushers
• Mixers
• Process machinery
• Large compressors
• Heavy-duty production equipment
• Large material-handling systems

---

8. AC Input with Precharge

The drive uses an AC Input with Precharge configuration.

The precharge function is important in high-power drive equipment because the DC bus contains substantial energy-storage components.

During energization, the precharge arrangement helps control the initial charging current of the DC bus capacitors.

This is particularly important in a large Frame 8 drive because uncontrolled capacitor charging could place unnecessary stress on upstream switching equipment, fuses, contactors, and internal components.

The precharge architecture therefore contributes to a more controlled power-up sequence.

---

9. No DC Terminals

The 20G1ABC567JN4NNNNN is specified as having no DC terminals.

This means the standard catalog configuration is based around the AC input arrangement rather than providing external DC-bus terminals as part of the basic drive configuration.

This is important when designing a system because external DC-bus connections should not be assumed simply because the drive contains an internal DC bus.

The electrical design should therefore follow the exact catalog configuration and the selected system architecture.

---

10. Filtering and CM Jumper

This model is supplied with a filtered configuration and the CM jumper installed.

These characteristics are important when the drive is installed in industrial environments containing sensitive control equipment, instrumentation, communication equipment, PLC systems, sensors, and other electrical loads.

The filtering arrangement helps control conducted high-frequency electrical noise.

The CM jumper configuration is also relevant to the drive’s common-mode behavior and grounding/filtering arrangement.

When installing a high-power VFD, these details should not be treated as minor options. Proper grounding, motor-cable routing, shield termination, cabinet bonding, and separation between power and control wiring all contribute to reliable operation.

---

11. Dynamic Braking

The standard configuration of 20G1ABC567JN4NNNNN has no dynamic braking.

This does not mean that the drive cannot be used in applications involving deceleration.

Rather, the standard catalog configuration does not include a built-in dynamic braking arrangement as part of this particular model configuration.

For applications requiring very rapid stopping of high-inertia loads, the braking requirements should be evaluated separately.

Examples include:

• High-inertia fans
• Long conveyors
• Centrifuges
• Large rotating machinery
• Rapid indexing machinery
• Hoisting-related applications
• Large mechanical rolls

If the application requires repeated rapid deceleration, the braking energy and thermal requirements need to be calculated before finalizing the drive configuration.

---

12. Embedded EtherNet/IP

One of the major advantages of the PowerFlex 755 architecture is its integration into industrial automation networks.

The 20G1ABC567JN4NNNNN includes embedded EtherNet/IP.

This allows the drive to participate in an automation architecture where drive control, speed references, status, diagnostics, and other operating information can be exchanged over the industrial network.

Typical network functions can include:

• Start/stop commands
• Speed reference
• Actual speed feedback
• Drive status
• Fault information
• Warning information
• Current information
• Torque-related information
• Diagnostic information
• Parameter-related data
• Process-control coordination

This is particularly useful in large production lines where the drive is controlled by a centralized automation system.

---

13. Enhanced LCD Full Numeric HIM

The Enhanced LCD Full Numeric HIM is another major characteristic of the JN4 configuration.

The HIM provides a local operator interface for commissioning, monitoring, troubleshooting, and parameter adjustment.

Compared with a basic no-HIM configuration, the presence of the enhanced interface makes local maintenance much easier.

Operators and maintenance personnel can use the interface to inspect:

• Drive status
• Fault codes
• Warning conditions
• Operating parameters
• Motor speed
• Output frequency
• Current
• Voltage
• Configuration values
• Diagnostic information
• Parameter settings

The higher-protection operator interface is especially useful for industrial MCC and cabinet environments where the operator needs access to the drive without exposing the main electronics to the surrounding environment.

---

14. Mechanical Parameters

The physical size is substantial because this is a high-power Frame 8 drive.

For installation planning, the 600 mm MCC depth should be considered together with:

• Cable bending radius
• Incoming power cables
• Motor cables
• Grounding conductors
• Control wiring
• Network cables
• Ventilation clearance
• Service access
• Door movement
• Maintenance access

The approximate 623 kg weight also means that mechanical handling must be planned carefully.

A suitable lifting and installation procedure should be established before the drive is delivered to its final position.

---

15. Product Introduction

The Allen-Bradley 20G1ABC567JN4NNNNN is a large-capacity PowerFlex 755 variable frequency drive designed for industrial applications requiring controlled operation of high-power three-phase motors.

Its combination of 400 VAC input, 567 A current capability, Frame 8 construction, air cooling, embedded EtherNet/IP, filtered input configuration, precharge, and enhanced operator interface makes it particularly appropriate for centralized industrial motor-control systems.

The 355 kW Low Duty rating gives the drive considerable capacity for variable-torque applications, while the 315 kW Normal Duty and 250 kW Heavy Duty ratings provide more conservative operating points for applications with greater load demands.

The 600 mm deep MCC-style construction also makes it suitable for installation in larger electrical rooms, motor control centers, and industrial control cabinets.

---

16. Main Applications

16.1 Conveyor Systems

The drive is well suited to large conveyor systems.

Conveyors often require controlled acceleration and deceleration because an abrupt start can produce mechanical shock, belt tension, product movement, and unnecessary stress on gearboxes and couplings.

Variable-speed control allows the conveyor speed to be adjusted according to production requirements.

Typical applications include:

• Mining conveyors
• Bulk material handling
• Cement plants
• Ports
• Warehouses
• Distribution systems
• Steel processing
• Aggregate handling

---

16.2 Large Pumps

Large centrifugal pumps are another strong application.

Variable-speed control can regulate flow without relying entirely on mechanical throttling.

This can provide better process control and may reduce energy consumption when the process does not require maximum pump speed.

Typical applications include:

• Water treatment
• Cooling-water circulation
• Industrial water systems
• Process pumping
• Chemical process systems
• Irrigation systems
• Large building infrastructure

---

16.3 Fans and Blowers

Large fans and blowers can benefit significantly from variable-speed control.

Fan loads are often highly dependent on rotational speed, so controlling speed rather than continuously operating at full speed can improve process efficiency.

Typical applications include:

• Industrial ventilation
• Furnace systems
• Dust collection
• Exhaust systems
• Process ventilation
• Cooling systems
• Air-handling equipment

---

16.4 Compressors

The high current capacity also makes the drive suitable for selected compressor applications.

Compressor systems can require precise control of speed and load.

The actual suitability depends on compressor type, starting torque, operating range, acceleration requirements, and manufacturer-specific motor characteristics.

---

16.5 Mixers and Process Machinery

Large industrial mixers can experience changing mechanical loads.

The PowerFlex 755 platform is appropriate for applications where controlled speed and torque are required.

Examples include:

• Chemical mixing
• Food processing machinery
• Material processing
• Mineral processing
• Industrial blending
• Large batch-processing equipment

---

16.6 Material Handling Equipment

The drive can also be applied to large material-handling machinery.

The ability to control acceleration and deceleration is particularly useful when equipment contains substantial rotating mass.

Applications can include:

• Hoist-related auxiliary machinery
• Transfer systems
• Large conveyors
• Roll handling
• Production-line transport
• Bulk material equipment

---

16.7 Large Industrial Production Machinery

The PowerFlex 755 family is also appropriate for large production machinery where motor speed needs to be coordinated with other equipment.

The integrated network architecture makes it easier to incorporate the drive into a larger control system.

---

17. Major Product Advantages

17.1 High Power Capacity

The 567 A current class gives this drive substantial capacity for large motors.

Its 355/315/250 kW duty ratings cover a broad range of industrial applications.

This makes it especially useful when smaller drives would be undersized.

---

17.2 Multiple Duty Ratings

The Low Duty, Normal Duty, and Heavy Duty ratings allow engineers to select the appropriate operating point according to the mechanical characteristics of the application.

This is more useful than simply selecting a drive based on motor kW.

The actual load profile should always be considered.

---

17.3 Integrated Industrial Communication

Embedded EtherNet/IP reduces the need to rely on a completely separate communication architecture for basic drive integration.

This is useful in automated factories where the drive needs to exchange information with controllers and other automation equipment.

---

17.4 Advanced Local Operator Interface

The Enhanced LCD Full Numeric HIM provides a practical interface for commissioning and troubleshooting.

This can reduce the time required for technicians to identify operating conditions and investigate faults.

---

17.5 High-Power Frame 8 Platform

Frame 8 provides a physical architecture designed for high-capacity industrial drives.

The larger enclosure provides the necessary space for power electronics, cooling components, bus structures, switching devices, protection elements, and control hardware.

---

17.6 Forced-Air Cooling

The air-cooled design provides a familiar industrial cooling architecture.

It avoids the need for liquid cooling infrastructure and is therefore practical for many conventional industrial electrical rooms.

However, the ventilation system must be maintained properly.

Dust accumulation, blocked filters, high ambient temperatures, or inadequate airflow can significantly affect drive reliability.

---

17.7 Filtered Configuration

The filtered configuration is useful in installations where electrical noise and EMC behavior are important considerations.

Correct installation remains essential because the drive’s internal filtering cannot compensate for poor grounding or incorrect cable installation.

---

17.8 Precharge System

The integrated precharge arrangement supports controlled DC-bus energization and is an important feature in a high-power drive.

---

17.9 Flexible Application Range

The combination of high current capacity, adjustable speed, industrial networking, and advanced control makes the drive suitable for a wide range of industrial machinery.

---

18. Five Same-Series or Closely Related Models

The following models are particularly useful when comparing the 20G1ABC567JN4NNNNN with other PowerFlex 755 configurations.

These models are useful for selecting a drive according to motor size and load requirements.

The 20G1ABC460 is a step down in current capacity, while the 20G1ABC540 is slightly smaller than the 567 A version.

The 20G1ABC650 and 20G1ABC750 move upward into larger current and power classes.

---

19. Five Popular Allen-Bradley Models for Comparison

These five models form a useful progression for large 400 VAC industrial applications.

The 460 A model is appropriate when the motor and application requirements are lower.

The 540 A model provides a moderate increase in current capability.

The 567 A model is particularly attractive when the application requires approximately 355 kW Low Duty capacity.

The 650 A and 750 A versions provide additional capacity for larger motors and higher-power process equipment.

---

20. 20G1ABC567JN4NNNNN vs. 20G1ABC567JN2NNNNN

These two models are especially closely related.

The electrical ratings are essentially the same.

The main distinction is the operator-interface configuration.

For installations where the operator needs a protected door-mounted interface, the JN4 configuration is particularly attractive.

For applications where a conventional handheld/local interface is sufficient, the JN2 configuration may be more practical.

---

21. 20G1ABC567JN4NNNNN vs. 20G1ABC567JN0NNNNN

The JN0 version is intended for applications where a local HIM is not required.

The JN4 version is more suitable when local operation, commissioning, diagnostics, and operator access are important.

22. Application Selection Guide

---

23. Installation Considerations

Because the 20G1ABC567JN4NNNNN is a large Frame 8 drive, installation planning is particularly important.

Electrical Installation

The incoming power system should be appropriately sized for the drive and motor.

Power cables should be selected according to current, installation method, ambient temperature, applicable electrical standards, and voltage-drop requirements.

Grounding should be designed carefully.

High-power VFD systems can produce significant electrical noise if grounding and cable routing are poorly designed.

---

Motor Cable Installation

Motor cables should be separated from sensitive control wiring wherever practical.

For long motor cables, additional consideration should be given to:

• Motor insulation
• Reflected-wave effects
• EMC
• Grounding
• Cable shielding
• Output reactor requirements
• Common-mode behavior

The actual motor cable length should be checked against the drive and motor requirements before commissioning.

---

Cooling and Ventilation

The drive uses forced-air cooling.

The cabinet or MCC must therefore provide sufficient airflow.

The installation should avoid:

• Blocked air passages
• Excessive ambient temperature
• Recirculation of hot air
• Dust accumulation
• Poor cabinet ventilation

A high-power drive can generate significant heat, so thermal management should be treated as a major design consideration.

---

Mechanical Handling

With an approximate weight of 623 kg, this is not a lightweight cabinet component.

The lifting, transportation, positioning, and mounting procedure should be planned in advance.

The floor, cabinet structure, mounting system, and handling equipment must be capable of supporting the actual equipment weight.

---

24. Maintenance Advantages

The large PowerFlex 755 architecture is designed for industrial serviceability.

Routine maintenance should include inspection of:

• Cooling fans
• Air passages
• Electrical connections
• Grounding connections
• Power terminals
• Motor connections
• Control wiring
• Network connections
• Alarm history
• Fault history
• Cabinet cleanliness
• Signs of overheating
• Signs of abnormal vibration

For high-power installations, preventive maintenance can be much more valuable than waiting for a drive failure.

---

25. Why Choose the 20G1ABC567JN4NNNNN?

The 20G1ABC567JN4NNNNN is particularly attractive when an application needs a combination of high current capacity, high motor power, network integration, local operator access, and an industrial MCC-style mechanical configuration.

Its main strengths can be summarized as follows:

1. 567 A high-current capacity
2. 355 kW Low Duty rating
3. 315 kW Normal Duty rating
4. 250 kW Heavy Duty rating

14. 600 mm deep MCC-style construction
15. Broad application range
16. Suitable for large industrial motors

---

26. Recommended Model Selection by Power Range

This table should be treated as a preliminary selection guide rather than a substitute for a complete drive-sizing calculation.

Motor nameplate current, overload requirements, ambient conditions, acceleration time, load inertia, operating speed, duty cycle, and installation conditions should all be considered.

---

27. Key Technical Summary

---

28. Overall Product Assessment

The Allen-Bradley 20G1ABC567JN4NNNNN is a high-capacity industrial drive designed for large motor applications where simple speed control is not enough.

Its combination of 567 A current capacity, 355/315/250 kW duty ratings, Frame 8 construction, forced-air cooling, embedded EtherNet/IP, filtered input configuration, precharge, and Enhanced LCD Full Numeric operator interface gives it a strong position in large industrial motor-control systems.

The JN4 configuration is particularly useful when local operator access and a higher-protection door-mounted interface are important.

For a large conveyor, pump, fan, blower, mixer, compressor, material-handling system, or production machine, the model provides a substantial amount of electrical and control capacity while maintaining the broader flexibility of the PowerFlex 755 platform.

From a selection perspective, the most important point is that 567 A should not be evaluated only against motor kW. The final selection should also consider motor nameplate current, load type, overload requirements, acceleration and deceleration requirements, operating speed range, braking requirements, ambient temperature, cable length, cabinet cooling, and the required control architecture.

For applications around the 315–355 kW range, especially where industrial network integration and a protected local operator interface are desired, the 20G1ABC567JN4NNNNN is a particularly strong configuration within the PowerFlex 755 family.
