Allen-Bradley 20G1AJF415AN0NNNNN PowerFlex 755 AC Drive

1. Product Overview

The Allen-Bradley 20G1AJF415AN0NNNNN is a high-power PowerFlex 755 air-cooled AC drive designed for large industrial motor-control applications.

It belongs to the PowerFlex 750-Series, specifically the PowerFlex 755 AC Drive family, and is intended for large three-phase motors operating from a 690 VAC industrial power system.

The drive has a nominal output-current class of 415 A and provides different motor-power ratings according to the required duty level. Its principal ratings are approximately 450 kW Light Duty, 400 kW Normal Duty, and 355 kW Heavy Duty.

This makes the model suitable for large pumps, fans, blowers, conveyors, process machinery, mining equipment, material-handling systems, cement equipment, and other large industrial machines.

The AN0 configuration is a large-frame, air-cooled arrangement with embedded EtherNet/IP, AC input with precharge, no DC terminals, filtered input, CM jumper removed, no dynamic braking, and no HIM.

The model uses a Frame 8, IP54 / Type 12, 800 mm deep MCC-style mechanical configuration.

The AN0 configuration is particularly appropriate for systems in which the drive is operated through a PLC, DCS, SCADA system, remote HMI, or industrial Ethernet network rather than through a dedicated local operator keypad.

The 20G1AJF415AN0NNNNN is therefore best regarded as a high-capacity industrial drive for applications where high motor power, high voltage, network integration, protected cabinet construction, and reliable variable-speed control are required.

---

4. Product Configuration

The catalog number 20G1AJF415AN0NNNNN represents a particular combination of electrical, mechanical, filtering, braking, and operator-interface characteristics.

The most important characteristics are:

• PowerFlex 755 architecture.
• 690 VAC three-phase operation.
• 415 A output-current class.
• Frame 8 construction.
• IP54 / Type 12 enclosure.
• 800 mm deep MCC-style cabinet.
• Air cooling.
• Embedded EtherNet/IP.
• AC input with precharge.
• No external DC terminals.
• Filtered input configuration.
• CM jumper removed.
• No integrated dynamic braking.
• Blank configuration without HIM.

The AN0 configuration is particularly useful in centralized automation systems.

In such installations, the drive does not necessarily need a local operator keypad because the primary interface can be provided through the plant PLC, DCS, SCADA system, or remote HMI.

This approach is common in large process plants where drives are installed inside electrical rooms or motor-control areas while operators control the process from a centralized control room.

---

5. Duty Ratings

The 20G1AJF415AN0NNNNN provides three principal duty ratings.

Duty Class	Continuous Current	1-Minute Current	3-Second Current	Approx. Motor Rating
Light Duty	460 A	506 A	—	450 kW
Normal Duty	415 A	457 A	639 A	400 kW
Heavy Duty	370 A	407 A	555 A	355 kW

These ratings allow the same drive platform to be applied to different types of industrial loads.

Light-Duty Operation

The 450 kW Light-Duty rating is intended for applications where the load is comparatively smooth and the overload demand is limited.

Typical examples include large centrifugal fans and pumps.

Such loads normally have relatively predictable torque characteristics and may not require frequent high-current acceleration.

Normal-Duty Operation

The 400 kW Normal-Duty rating provides the central operating point for many industrial applications.

It is suitable for large motors where the load may fluctuate but does not continuously demand the high overload capability associated with Heavy-Duty applications.

Heavy-Duty Operation

The 355 kW Heavy-Duty rating is intended for more demanding mechanical loads.

Typical examples can include:

• Heavy conveyors.
• Large mixers.
• Crushers.
• Material-processing machinery.
• Certain positive-displacement pumps.
• Heavy-duty production machinery.

The lower Heavy-Duty motor-power rating reflects the greater current and thermal margin required for overload operation.

---

6. Electrical Characteristics

The 20G1AJF415AN0NNNNN is designed for a 690 VAC three-phase industrial supply.

The 690 V class is particularly useful for large motor installations.

At a given motor power, a higher voltage allows the required current to be kept lower than would be necessary at a lower voltage.

This can be advantageous for large industrial electrical systems because it can simplify power-distribution design and reduce the current carried by major feeders.

For high-power motors, 690 V systems are commonly used where the plant electrical architecture supports this voltage class.

The drive’s input configuration is AC input with precharge.

The precharge circuit controls the initial charging of the internal DC-link capacitors during energization.

The model does not include dedicated external DC terminals in the specified configuration.

---

7. Input Filtering and CM Jumper

The 20G1AJF415AN0NNNNN is configured as Filtered, CM Jumper Removed.

These two characteristics are relevant to the electrical installation.

The filtering arrangement helps manage high-frequency electrical noise associated with switching power electronics.

The CM jumper configuration affects the common-mode behavior of the drive and must be considered together with the grounding system, motor cable construction, cable length, motor insulation, and plant EMC requirements.

In a large industrial installation, correct cable routing and grounding practices remain essential.

The drive filter should therefore be regarded as one part of the complete EMC design rather than as an independent solution.

---

8. Dynamic Braking

The specified AN0 configuration has no integrated dynamic-braking transistor.

This is an important consideration when the drive is used with high-inertia loads.

During rapid deceleration, an induction motor can return energy to the drive’s DC bus.

If this energy cannot be absorbed or otherwise managed, the DC-bus voltage can rise.

Applications requiring aggressive deceleration should therefore be evaluated carefully.

Potential examples include:

• High-inertia conveyors.
• Centrifuges.
• Large rotating machinery.
• Hoisting equipment.
• Rapid-cycle machinery.
• Certain winding systems.

For these applications, the complete system may require an appropriate braking resistor arrangement, regenerative solution, controlled deceleration strategy, or another method of managing regenerated energy.

For applications such as large centrifugal pumps and fans, where acceleration and deceleration can normally be controlled gradually, the absence of an integrated dynamic-braking transistor is generally less significant.

---

9. Embedded EtherNet/IP

The PowerFlex 755 platform provides integrated industrial-network capability, and the 20G1AJF415AN0NNNNN is configured with embedded EtherNet/IP.

This makes the drive suitable for centralized automation architectures.

A typical system can be arranged as:

PLC / DCS → EtherNet/IP → PowerFlex 755 → Motor

The network can be used to exchange:

• Start commands.
• Stop commands.
• Speed references.
• Frequency references.
• Drive status.
• Motor current.
• Output frequency.
• Speed information.
• Fault information.
• Alarm information.
• Diagnostic information.
• Parameter information.

This provides much greater operational visibility than a simple hardwired start/stop arrangement.

For large plants containing many high-power drives, network communication can significantly simplify the overall control architecture.

---

10. AN0 Configuration and Operator Interface

A major characteristic of the 20G1AJF415AN0NNNNN is its Blank / No HIM configuration.

HIM refers to the Human Interface Module.

This model is therefore intended primarily for applications where local keypad operation is not required.

The drive can instead be managed through:

• PLC control.
• DCS control.
• SCADA systems.
• Remote HMI.
• EtherNet/IP.
• Engineering software.

This configuration is particularly suitable for centralized industrial facilities.

For example, a pump drive may be physically installed in an electrical room while the operator works from a control room.

In such a situation, a dedicated local keypad may not be necessary.

For applications requiring frequent local operation, commissioning, or troubleshooting directly at the drive, a related JN4 configuration may be more appropriate.

---

11. Mechanical Construction

The 20G1AJF415AN0NNNNN uses a Frame 8 mechanical configuration.

The approximate Frame 8 IP54 / Type 12 reference dimensions are:

Mechanical Parameter	Approximate Value
Height	2477 mm
Width	600 mm
Depth	800 mm
Depth with Filter Arrangement	Approximately 898 mm
Approximate Weight	644 kg
Frame	8
Enclosure Protection	IP54
Enclosure Type	Type 12
Cabinet Style	MCC Style

These values should be treated as engineering reference dimensions for the standard Frame 8 cabinet arrangement.

The final physical arrangement can change when additional cabinet sections, disconnect equipment, option cabinets, line-side components, or other accessories are incorporated.

For actual installation and transportation planning, the project-specific mechanical drawing should be used.

At approximately 644 kg, this is substantial industrial equipment and should be handled using suitable lifting and installation equipment.

---

12. Cooling System

The drive uses forced-air cooling.

Large power semiconductor devices and other internal components generate considerable heat during operation.

The cooling system removes this heat from the power section and transfers it into the surrounding environment.

Proper ventilation is therefore important.

The electrical room or equipment area should be designed so that:

• Airflow is not obstructed.
• Ambient temperature remains within the permitted operating range.
• Exhaust heat does not accumulate around the drive.
• Cooling fans have sufficient airflow.
• Air passages remain clean.
• Maintenance access is maintained.

For large Frame 8 drives, the heat generated by the power section can be significant.

A suitable HVAC and ventilation strategy should therefore be considered as part of the overall installation design.

---

13. Product Applications

13.1 Large Industrial Pumps

Large pumps are one of the most suitable application areas for the 20G1AJF415AN0NNNNN.

Potential applications include:

• Water-treatment pumps.
• Cooling-water pumps.
• Industrial circulation pumps.
• Process pumps.
• Mine dewatering pumps.
• Raw-water pumps.
• Utility pumps.

Variable-speed control allows the motor speed to follow process demand.

This can improve process control and reduce the need to operate the motor continuously at full speed.

The drive can be connected to pressure, flow, level, or other process feedback systems through the plant control architecture.

---

14. Large Fans and Blowers

Large centrifugal fans and blowers are another strong application.

Typical applications include:

• Furnace ventilation.
• Combustion-air systems.
• Exhaust systems.
• Dust collection.
• Cement-plant ventilation.
• Mining ventilation.
• Industrial air handling.
• Process ventilation.

Fan speed can be adjusted according to airflow or pressure requirements.

The 450 kW Light-Duty capability is particularly relevant to large fan applications where the load profile is relatively stable.

---

15. Conveyors

Large conveyor systems often require controlled acceleration and speed regulation.

The 20G1AJF415AN0NNNNN can be used in suitable conveyor applications within its rated current and duty limits.

Typical industries include:

• Mining.
• Cement.
• Aggregate.
• Ports.
• Bulk material handling.
• Steel.
• Industrial manufacturing.

Variable-speed control can provide:

• Controlled acceleration.
• Controlled deceleration.
• Adjustable belt speed.
• Reduced mechanical shock.
• Improved process coordination.
• Better integration with plant automation.

For long conveyors, the acceleration profile is particularly important because rapid changes in torque can place considerable stress on belts, gearboxes, couplings, and mechanical structures.

---

16. Mining Applications

The drive is well suited to many large-motor applications found in mining operations.

Potential applications include:

• Mine ventilation fans.
• Dewatering pumps.
• Conveyors.
• Crushing equipment.
• Material-handling systems.
• Processing equipment.
• Large auxiliary machinery.

The IP54 / Type 12 cabinet construction is advantageous in industrial environments where environmental protection is more important than it would be for an open-frame drive.

However, environmental conditions must still be controlled according to the drive’s permitted operating conditions.

---

17. Cement and Aggregate Applications

Cement plants and aggregate facilities contain many high-power motors.

The 20G1AJF415AN0NNNNN can be applied to suitable equipment such as:

• Process fans.
• Conveyors.
• Crushers.
• Large pumps.
• Material-handling systems.
• Dust-collection fans.
• Processing machinery.

The 690 VAC architecture is especially useful where large motors are distributed across a high-voltage motor system.

---

18. Steel and Metal Processing

Large variable-speed motors are widely used in metal-processing equipment.

Potential applications include:

• Cooling systems.
• Large fans.
• Pumps.
• Conveyors.
• Material-handling equipment.
• Process machinery.
• Auxiliary drive systems.

The PowerFlex 755 platform provides the network connectivity and control functionality required for integration into larger production systems.

---

19. Water and Wastewater Systems

Large water and wastewater facilities can contain numerous high-power pumps and blowers.

Typical applications include:

• Raw-water pumping.
• Transfer pumping.
• High-lift pumping.
• Aeration blowers.
• Cooling systems.
• Sludge-processing equipment.
• Large ventilation systems.

The variable-speed functionality can help match equipment operation to actual process demand.

Network integration also makes it possible to monitor drive status from a central control system.

---

20. Process Industry Applications

The 20G1AJF415AN0NNNNN can also be applied to large process machinery.

Potential applications include:

• Chemical processing.
• Pulp and paper.
• Mineral processing.
• Food-processing utilities.
• Pharmaceutical utilities.
• Industrial water systems.
• Bulk material processing.
• General process equipment.

The final selection should always be based on the motor nameplate current and actual load profile.

---

21. Main Product Advantages

21.1 High 690 VAC Power Capability

The 690 VAC voltage class allows the drive to control very large motors.

This makes the product suitable for high-power industrial systems where lower-voltage drives would require substantially higher current.

---

21.2 415 A Output Class

The 415 A current rating places the model in a high-capacity industrial category.

It provides a useful step above the 370 A model while remaining below the 460 A and 500 A classes.

This makes it a practical choice for motors whose current requirements fall into the upper 300 A to low 400 A range.

---

21.3 450 kW Light-Duty Rating

The 450 kW Light-Duty rating gives the drive substantial capacity for suitable centrifugal-load applications.

Large pumps and fans can particularly benefit from this rating.

---

21.4 400 kW Normal-Duty Rating

The 400 kW Normal-Duty rating provides a strong reference point for general industrial motor applications.

It is suitable for large machines that require normal levels of overload capability.

---

21.5 355 kW Heavy-Duty Rating

For demanding mechanical loads, the 355 kW Heavy-Duty rating provides a more conservative motor-power selection.

This can be valuable for equipment with higher torque requirements and more demanding acceleration profiles.

---

21.6 IP54 / Type 12 Construction

The IP54 / Type 12 enclosure provides improved environmental protection compared with an open-frame installation.

This is useful in industrial electrical rooms, process facilities, manufacturing plants, and other locations where dust and normal industrial contamination must be considered.

---

21.7 Embedded EtherNet/IP

Embedded EtherNet/IP is a major advantage in modern automation systems.

It allows the drive to become part of the plant network without treating the drive as an isolated motor-control device.

This supports centralized monitoring, control, diagnostics, and parameter management.

---

21.8 No-HIM Architecture

The absence of a HIM can be an advantage rather than a disadvantage in centralized installations.

A drive that is controlled from a PLC, DCS, or SCADA system does not necessarily need a local operator keypad.

This can provide a cleaner cabinet arrangement and is well suited to installations where local operation is not part of the normal operating procedure.

---

21.9 Flexible Power Selection

The three duty classes provide useful flexibility.

A single drive family can cover different motor sizes depending on the load profile.

This simplifies product selection across large industrial projects.

---

22. Comparison with the 370 A Model

The 415 A model provides a meaningful increase in capacity over the 370 A model.

The 370 A version is suitable when the motor current is lower.

The 415 A version is more appropriate when the motor current or duty requirements approach the upper range of the 370 A model.

---

23. Five Recommended Models from the Same Series

20G1AJF500AN0NNNNN	690 VAC	500 A	530 kW	500 kW	400 kW	8	IP54 / Type 12, No HIM

The 690 V PowerFlex 755 selection range confirms the progression from 330 A through 500 A and the corresponding Light-, Normal-, and Heavy-Duty motor ratings.

---

24. Recommended JN0 Models

If the application does not require a local HIM, the following JN0 configurations are also relevant.

Model	Voltage	Current	LD	ND	HD	Frame	HIM
20G1AJF265JN0NNNNN	690 VAC	265 A	315 kW	250 kW	200 kW	8	No HIM
20G1AJF330JN0NNNNN	690 VAC	330 A	355 kW	315 kW	250 kW	8	No HIM
20G1AJF370JN0NNNNN	690 VAC	370 A	400 kW	355 kW	300 kW	8	No HIM

The 25C-D030N114 belongs to the PowerFlex 527 family.

It is aimed at machine applications where network-based motor control and automation integration are important.

Its smaller 30 A class makes it suitable for applications that are far below the 415 A capacity of the target model.

It can therefore be viewed as a machine-level alternative rather than a direct power replacement.

---

28. Popular Model: 20F1AND302JA0NNNNN

The 20F1AND302JA0NNNNN is a PowerFlex 753 drive in the 480 VAC class.

Its approximately 302 A output class makes it suitable for large industrial motors.

Typical applications include:

• Large pumps.
• Large fans.
• Conveyors.
• Industrial machinery.
• Process equipment.
• Material handling.

---

29. Popular Model: 20G1AJE460JN4NNNNN

The 20G1AJE460JN4NNNNN belongs to the PowerFlex 755 family and is intended for large 600 VAC motor systems.

Its 460 A current class provides substantial motor capacity.

The JN4 configuration also provides a local enhanced operator interface.

This makes it useful where both high motor power and local drive access are required.

---

30. Popular Model: 20G1AJF415JN4NNNNN

The 20G1AJF415JN4NNNNN is especially close to the target model.

Both models use:

• 690 VAC.
• 415 A.

Mechanical Specification	Approximate Value
Model	20G1AJF415AN0NNNNN
Frame	8
Height	2477 mm
Width	600 mm
Basic Depth	800 mm
Depth with Filter Arrangement	Approximately 898 mm

---

33. Installation Considerations

Electrical Room

The equipment should be installed in a suitable electrical environment with adequate space for operation and maintenance.

The large enclosure size requires careful floor planning.

Ventilation

Forced-air cooling means the room must be capable of removing the heat generated by the drive.

Insufficient ventilation can increase internal temperature and reduce component life.

Cable Routing

Power cables and control/network cables should be routed appropriately.

Motor cables should be separated from sensitive signal wiring where practical.

Grounding

A suitable grounding system is essential.

The grounding design should account for the drive, motor, cabinet, cable shields, and overall plant electrical architecture.

Maintenance Access

Adequate front access should be maintained.

Technicians need sufficient room for inspection, testing, component replacement, and electrical isolation procedures.

35. Advantages for Centralized Automation

The AN0 configuration is particularly well suited to centralized automation.

A typical large plant may have dozens of drives located in different electrical rooms.

Operators do not necessarily need to stand beside each drive.

Instead, the control system can provide:

• Remote start/stop.
• Speed adjustment.
• Status monitoring.
• Fault monitoring.
• Alarm monitoring.
• Current monitoring.
• Process control.
• Maintenance information.

This makes the No-HIM configuration practical for large plants where the drive is normally controlled remotely.

36. Maintenance Advantages

The PowerFlex 755 platform provides extensive drive information for maintenance and troubleshooting.

A network-connected installation can allow maintenance personnel to review:

• Drive status.
• Fault conditions.
• Alarm conditions.
• Current.
• Speed.
• Frequency.
• Operating conditions.
• Parameter settings.
• Communication status.

This can shorten troubleshooting time because the technician can obtain information without physically accessing every operating parameter at the drive.

For this reason, the AN0 configuration is particularly appropriate for centralized control environments.

40. Overall Product Assessment

The Allen-Bradley 20G1AJF415AN0NNNNN is a high-capacity industrial variable-frequency drive designed for large three-phase motors operating on a 690 VAC supply.

Its key electrical ratings are:

415 A nominal current

450 kW Light Duty

400 kW Normal Duty

355 kW Heavy Duty

These ratings make it suitable for large pumps, fans, conveyors, process machinery, mining equipment, cement equipment, material-handling systems, and other large industrial loads.

Its Frame 8 / IP54 / Type 12 / 800 mm deep MCC-style construction makes it appropriate for substantial industrial electrical installations.

The forced-air cooling system supports high-power operation, while the enclosure provides additional environmental protection compared with an open-frame drive.

The embedded EtherNet/IP capability makes the drive suitable for integration into PLC, DCS, SCADA, and other industrial automation architectures.

The AN0 configuration without HIM is particularly appropriate for centralized systems.

Where the drive is installed in an electrical room and controlled from a central control room, the absence of a local HIM is often a practical configuration choice.

If local operator access is required, the corresponding JN4 configuration can be considered.

The absence of integrated dynamic braking is an important application consideration.

Large high-inertia loads should be evaluated carefully to determine whether external braking or regenerative equipment is required.

Overall, the 20G1AJF415AN0NNNNN is best suited to large industrial systems where high motor power, 690 VAC operation, robust cabinet construction, Ethernet-based automation, and centralized control are the primary requirements.

42. Final Recommendation

For a 690 VAC, three-phase large-motor application, the 20G1AJF415AN0NNNNN is a strong choice when the motor current and application duty fall within the 415 A class.

It is particularly suitable for centralized industrial automation systems where the drive is normally operated through PLC, DCS, SCADA, or remote HMI systems.

For lower motor-current requirements, the 20G1AJF370AN0NNNNN or 20G1AJF330AN0NNNNN can be considered.

For higher motor-current requirements, the 20G1AJF460AN0NNNNN or 20G1AJF500AN0NNNNN provides additional capacity.

Where a local operator interface is required, the 20G1AJF415JN4NNNNN is the more appropriate configuration to evaluate.

From an engineering standpoint, the most important selection factors are the motor nameplate current, required duty classification, overload profile, acceleration and deceleration requirements, braking requirements, 690 VAC supply availability, cabinet dimensions, cooling requirements, and automation-network architecture.

The combination of 415 A capacity, 450/400/355 kW duty ratings, 690 VAC operation, Frame 8 construction, IP54 / Type 12 protection, embedded EtherNet/IP, and a centralized no-HIM configuration makes the 20G1AJF415AN0NNNNN a strong high-power solution for large industrial motor-control systems.
