---

5. Product Series: PowerFlex 755

The PowerFlex 755 is a high-performance member of the PowerFlex 750-Series.

It is intended for larger industrial applications where a conventional compact machine drive is no longer sufficient.

The series provides a broad range of voltage, current, power, enclosure, communication, braking, and operator-interface configurations.

The 20G1AJF460JN0NNNNN represents the 690 VAC / 460 A / Frame 8 segment of this product family.

The same basic platform can be selected at different current ratings, allowing engineers to standardize drive architecture across multiple large motors.

For example, closely related 690 V configurations include 265 A, 330 A, 370 A, 415 A, 460 A, and 500 A classes.

This makes the PowerFlex 755 family practical for large plants with many different motor sizes.

---

6. Electrical Rating

The drive operates in the 690 VAC three-phase class.

This voltage level is particularly relevant to large industrial motor systems.

For a given motor power, increasing motor voltage allows the required current to be reduced compared with a lower-voltage motor system.

This can be beneficial for:

• Large motor feeders.
• Long motor cable runs.
• Large process plants.
• Mining installations.
• Cement plants.
• Water infrastructure.
• Large ventilation systems.
• Heavy industrial production.

The 460 A current class provides a substantial power range while maintaining the same general Frame 8 mechanical architecture used by nearby models.

---

7. Duty Ratings

The drive provides three primary operating-duty categories.

Duty	Continuous Current	1-Minute Current	3-Second Current	Motor Rating
Light Duty	500 A	550 A	—	500 kW
Normal Duty	460 A	506 A	690 A	450 kW
Heavy Duty	375 A	563 A	675 A	375 kW

These ratings are important because the appropriate drive size depends on more than the motor’s nameplate kW.

The motor current, torque characteristics, overload requirement, acceleration profile, deceleration profile, and operating cycle should all be considered.

A 450 kW motor operating a relatively smooth pump load may have very different drive requirements from a 375 kW motor operating a high-inertia or high-torque machine.

---

8. Light-Duty Operation – 500 kW

The 500 kW Light-Duty rating is the highest nominal motor-power rating associated with this configuration.

It is particularly useful for relatively smooth variable-torque applications.

Typical examples include:

• Large centrifugal pumps.
• Large centrifugal fans.
• Cooling-water systems.
• Ventilation systems.
• Large process blowers.
• Industrial air systems.
• Utility pumps.

Variable-speed control can allow the process to operate according to actual demand instead of maintaining maximum motor speed continuously.

---

9. Normal-Duty Operation – 450 kW

The 450 kW Normal-Duty rating is suitable for a broad range of general industrial equipment.

Typical applications include:

• Large conveyors.
• Process pumps.
• Large blowers.
• Material-handling systems.
• Industrial fans.
• Process machinery.
• General production equipment.

Normal-Duty operation is often the appropriate selection category for industrial machinery where moderate overload capacity is required but the load is not considered extremely severe.

---

10. Heavy-Duty Operation – 375 kW

The 375 kW Heavy-Duty rating provides a more conservative motor-power selection for applications requiring greater overload capability.

Potential applications include:

• Heavy conveyors.
• Mixers.
• Crushers.
• High-inertia machinery.
• Heavy material-handling equipment.
• Certain process machines.

The Heavy-Duty rating should be considered when the machine has significant starting torque, repeated acceleration, high inertia, or demanding cyclic loading.

---

11. Embedded EtherNet/IP

One of the important characteristics of the 20G1AJF460JN0NNNNN is its embedded EtherNet/IP communication.

This allows the drive to be incorporated directly into an industrial Ethernet control architecture.

A typical arrangement can be represented 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 is particularly useful in large facilities where the drive is located inside an electrical room while the operator works from a centralized control station.

---

12. Centralized Control Architecture

The Blank / No HIM configuration is well suited to centralized automation.

The drive does not need to depend on a permanent local keypad for normal operation.

Instead, the control architecture can be based on:

• PLC.
• DCS.
• SCADA.
• Remote HMI.
• EtherNet/IP.
• Plant-wide control systems.

For example:

Process Pressure Transmitter

↓

PLC

↓

EtherNet/IP

↓

20G1AJF460JN0NNNNN

↓

690 VAC Motor

This arrangement is common for large pumping, ventilation, material-handling, and process applications.

---

13. Blank / No HIM Configuration

The model is configured with a Blank / No HIM arrangement.

HIM stands for Human Interface Module.

The absence of a local HIM can be advantageous where the plant already has a centralized operator interface.

Typical examples include:

• Pump stations.
• Water-treatment plants.
• Mining electrical rooms.
• Cement plants.
• Process plants.
• Centralized MCC rooms.
• Large automated production facilities.

In these installations, operators normally interact with the drive through a PLC, DCS, SCADA system, or remote HMI.

A related JN4 configuration can be considered when a dedicated enhanced local HIM is required.

---

14. JN0 Versus JN4

The 20G1AJF460JN4NNNNN is a closely related configuration.

Feature	20G1AJF460JN0NNNNN	20G1AJF460JN4NNNNN
Voltage	690 VAC	690 VAC
Current	460 A	460 A
Light Duty	500 kW	500 kW
Normal Duty	450 kW	450 kW
Heavy Duty	375 kW	375 kW
Frame	8	8
Enclosure	IP54 / Type 12	IP54 / Type 12
Cooling	Forced Air	Forced Air
EtherNet/IP	Embedded	Embedded
Input	AC with Precharge	AC with Precharge
Dynamic Braking	None	None
CM Jumper	Installed	Installed
HIM	Blank / No HIM	Enhanced LCD / Full Numeric
HIM Protection	Not Applicable	IP66 / NEMA Type 4X/12 class
Typical Control Style	Centralized	Local + Centralized

The main practical difference is the operator-interface configuration.

The JN0 model is better suited to installations where the drive is normally operated remotely.

The JN4 model is better suited to applications where technicians or operators require an enhanced local interface.

---

15. Input Precharge

The drive uses AC input with precharge.

The precharge system manages the initial energization of the internal DC-link capacitors.

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

The precharge arrangement contributes to controlled startup of the power section.

The specified configuration does not provide external DC terminals.

---

16. No DC Terminals

The 20G1AJF460JN0NNNNN is configured for AC input and does not provide DC terminals in this configuration.

This makes the drive a conventional AC-input PowerFlex 755 arrangement rather than a common-DC-bus configuration.

For a conventional motor-control application, the AC-input configuration is straightforward.

For systems requiring shared DC bus operation or special regenerative architectures, a different configuration should be evaluated.

---

17. Input Filtering

The model is specified as Filtered.

The filtering arrangement contributes to management of high-frequency electrical noise associated with power-electronic switching.

For a high-power drive installation, overall electromagnetic compatibility also depends on:

• Grounding.
• Shielding.
• Motor cable design.
• Cable routing.
• Cabinet construction.
• Separation of control and power cables.
• Motor installation.
• Earthing arrangement.

The filter is therefore one part of the overall EMC design.

---

18. CM Jumper Installed

The JN0 configuration specifies the CM jumper installed.

The common-mode configuration should be considered together with the complete electrical installation.

Relevant factors include:

• Grounding system.
• Motor cable construction.
• Cable length.
• Motor insulation.
• EMC requirements.
• Leakage current.
• Input power-system configuration.
• Installation environment.

The correct configuration should be confirmed against the specific electrical system and project requirements.

---

19. Dynamic Braking

The specified configuration has no dynamic braking.

This is an important selection consideration for high-inertia applications.

During deceleration, a motor can return energy to the drive’s DC bus.

If the deceleration is too aggressive, DC-bus voltage can rise.

For applications with significant regenerative energy, engineers should evaluate:

• Deceleration time.
• Load inertia.
• Motor speed.
• Regenerative energy.
• Braking requirements.
• External braking options.
• Regenerative drive alternatives.

For centrifugal pumps and fans, controlled deceleration is usually more practical than very rapid stopping.

For high-inertia machinery, braking requirements require more careful engineering.

---

20. Forced-Air Cooling

The drive uses forced-air cooling.

At this power level, substantial heat is generated by the power electronics.

The cooling system removes this heat through forced airflow.

The electrical installation should therefore provide adequate:

• Airflow.
• Ventilation.
• Ambient temperature control.
• Heat removal.
• Cooling-component access.
• Cabinet clearance.

Large installations should consider the combined heat output of all drives and electrical equipment in the room.

---

21. Frame 8 Construction

The 20G1AJF460JN0NNNNN uses Frame 8 construction.

Frame 8 is intended for large industrial drives.

The mechanical arrangement is significantly larger than compact machine-level drives.

The Frame 8 architecture is appropriate for:

• Large motor control.
• MCC rooms.
• Electrical rooms.
• Process plants.
• Mining facilities.
• Large utility systems.
• Heavy industrial installations.

The substantial physical size should be considered during engineering, transportation, installation, and maintenance planning.

---

22. Enclosure Protection

The drive is configured with IP54 / Type 12 enclosure protection.

This is an important advantage in industrial environments.

The protected cabinet construction is suitable for many indoor industrial applications where equipment requires protection against dust and incidental moisture.

Typical installation environments include:

• Electrical rooms.
• MCC rooms.
• Process plants.
• Manufacturing facilities.
• Water-treatment facilities.
• Cement plants.
• Mining electrical rooms.
• Utility facilities.

The IP54 / Type 12 rating does not mean that the drive can be installed without environmental consideration.

Ambient temperature, humidity, corrosive gases, dust concentration, altitude, ventilation, and condensation must still be evaluated.

---

23. Mechanical Dimensions and Weight

The following dimensions represent the approximate standard Frame 8 IP54 / Type 12 MCC-style cabinet reference.

Mechanical Parameter	Approximate Value
Model	20G1AJF460JN0NNNNN
Frame	8
Height	2477 mm
Width	600 mm
Depth	800 mm
Depth with Filter Arrangement	Approximately 898 mm
Approximate Weight	644 kg
Enclosure	IP54
Enclosure Type	Type 12
Cabinet Style	MCC Style
Cooling	Forced Air

These dimensions are particularly important for project layout.

At approximately 2.477 m high, the cabinet may require special attention to room height, transport paths, door clearances, lifting points, and installation access.

The approximately 644 kg cabinet weight also requires appropriate handling equipment.

Where option cabinets or additional sections are included, the overall width and weight can increase substantially.

For example, the Frame 8 configuration with drive and option cabinets has an approximate width of 1200 mm and approximate weight of 1166 kg.

---

24. Large Pump Applications

The 20G1AJF460JN0NNNNN is particularly suitable for large pumping systems.

Typical applications include:

• Raw-water pumps.
• High-lift pumps.
• Cooling-water pumps.
• Process-water pumps.
• Transfer pumps.
• Industrial circulation pumps.
• Mine dewatering pumps.
• Utility pumping systems.

The 500 kW Light-Duty rating can be particularly useful for large centrifugal pump applications.

Variable-speed control allows pump speed to follow actual process requirements.

For example:

Pressure Sensor → PLC → Speed Reference → PowerFlex 755 → Pump Motor

This provides a practical closed-loop process-control architecture.

---

25. Large Fan Applications

Large centrifugal fans are another strong application area.

Potential equipment includes:

• Furnace fans.
• Exhaust fans.
• Combustion-air fans.
• Dust-collection fans.
• Cement-process fans.
• Mine ventilation fans.
• Large ventilation systems.
• Industrial blowers.

Large centrifugal fan systems frequently benefit from variable-speed operation.

Rather than running the motor continuously at full speed and controlling airflow primarily through mechanical restriction, the drive can adjust motor speed according to actual process requirements.

---

26. Blower Applications

The drive can be used for high-power industrial blowers.

Potential applications include:

• Process air.
• Combustion air.
• Aeration.
• Pneumatic systems.
• Industrial ventilation.
• Process gas movement.
• Dust-collection systems.

The appropriate duty rating should be determined from actual blower torque characteristics and motor current.

---

27. Conveyor Applications

The 460 A PowerFlex 755 is well suited to many large conveyor systems.

Potential applications include:

• Mining conveyors.
• Aggregate conveyors.
• Cement conveyors.
• Port conveyors.
• Bulk-material conveyors.
• Steel-handling conveyors.
• Production conveyors.

Variable-speed operation can provide controlled acceleration and deceleration.

This can help reduce mechanical shock to:

• Belts.
• Gearboxes.
• Couplings.
• Bearings.
• Conveyor structures.

For conveyors with very high inertia or frequent regenerative operation, braking requirements should be evaluated separately.

---

28. Mining Applications

Large mining facilities often require high-power drives.

Potential applications include:

• Mine ventilation.
• Dewatering.
• Ore conveyors.
• Material handling.
• Processing equipment.
• Crushing systems.
• Large fans.
• Auxiliary machinery.

The combination of 690 VAC operation, 460 A current capacity, IP54 / Type 12 enclosure construction, and embedded EtherNet/IP makes the configuration suitable for appropriate indoor electrical-room installations.

The actual environmental conditions must be checked carefully in mining applications because dust, temperature, humidity, and corrosive conditions can vary considerably.

---

29. Cement and Aggregate Applications

The drive is also suitable for high-power equipment used in cement and aggregate facilities.

Typical applications include:

• Large process fans.
• Dust-collection fans.
• Conveyors.
• Pumps.
• Blowers.
• Material-handling systems.
• Crushing equipment.
• Utility systems.

Cement and aggregate equipment frequently involves large motors and long operating periods.

The ability to regulate speed according to actual process demand can provide better operational control.

---

30. Steel and Metal Processing

Potential steel and metal-processing applications include:

• Cooling-water pumps.
• Large fans.
• Material conveyors.
• Process equipment.
• Utility systems.
• Material-handling equipment.
• Production machinery.

The drive can be incorporated into a larger PLC or DCS-controlled production architecture through EtherNet/IP.

---

31. Water and Wastewater Applications

High-power water and wastewater equipment is another suitable application category.

Potential equipment includes:

• Raw-water pumps.
• High-lift pumps.
• Transfer pumps.
• Industrial wastewater pumps.
• Large aeration blowers.
• Cooling-water systems.
• Process-water circulation.

The variable-speed drive can be used to match motor output to:

• Flow.
• Pressure.
• Tank level.
• Process demand.
• System pressure.

This can be more flexible than fixed-speed operation.

---

32. Process Industry Applications

The drive is suitable for a broad range of large process applications.

Potential industries include:

• Pulp and paper.
• Mineral processing.
• Cement.
• Steel.
• Water treatment.
• General manufacturing.
• Chemical processing.
• Industrial utilities.
• Bulk-material handling.
• Mining.

The exact suitability depends on motor characteristics and process requirements.

---

46. Installation Considerations

Electrical Supply

The electrical system should be suitable for the 690 VAC three-phase voltage class.

Upstream isolation, circuit protection, grounding, cable sizing, and short-circuit considerations should be established during engineering.

---

Motor Current

The motor nameplate current is one of the most important selection parameters.

The 460 A rating should not be treated simply as a motor-kW number.

Actual motor current and duty profile should determine whether the Light-Duty, Normal-Duty, or Heavy-Duty rating is appropriate.

---

Motor Cable

Motor cable selection should consider:

• Motor current.
• Cable length.
• Installation environment.
• EMC requirements.
• Motor insulation.
• Shielding.
• Grounding.
• Temperature.

---

Cooling

Because the drive is forced-air cooled, sufficient airflow must be available.

The electrical room should have adequate heat-removal capability.

---

Mechanical Installation

The approximately 2.477 m cabinet height and approximately 644 kg reference weight should be considered during:

• Transportation.
• Unloading.
• Lifting.
• Floor preparation.
• Cabinet placement.
• Maintenance planning.

---

47. Maintenance Advantages

The embedded network architecture can simplify maintenance.

The control system can monitor information such as:

• Running status.
• Stop status.
• Fault status.
• Alarm status.
• Motor current.
• Output frequency.
• Speed reference.
• Drive status.
• Communication status.
• Diagnostic information.

This allows maintenance personnel to identify abnormal conditions without always approaching the physical drive cabinet.

In large plants, this can be especially useful because Frame 8 equipment may be located in a dedicated electrical room away from the production area.

---

48. Standardization Benefits

The PowerFlex 755 family provides a useful standardization platform for large motor applications.

For example, a plant may use:

20G1AJF330JN0NNNNN

for a lower-power motor,

20G1AJF370JN0NNNNN

for a larger motor,

20G1AJF415JN0NNNNN

for a still larger motor,

20G1AJF460JN0NNNNN

for a 460 A requirement,

and

20G1AJF500JN0NNNNN

for a higher-capacity motor.

This common architecture can simplify:

• PLC programming.
• Network architecture.
• Maintenance training.
• Spare-parts management.
• Drive replacement.
• Commissioning.
• Troubleshooting.

51. Overall Product Assessment

The Allen-Bradley 20G1AJF460JN0NNNNN is a high-capacity industrial AC drive designed for large three-phase motors.

Its principal electrical characteristics are:

690 VAC

460 A

500 kW Light Duty

450 kW Normal Duty

375 kW Heavy Duty

The drive uses Frame 8 construction with an IP54 / Type 12 MCC-style enclosure and forced-air cooling.

The combination of high voltage and high current makes it suitable for large industrial motors used in pumping, ventilation, material handling, mining, cement, water treatment, process manufacturing, and other heavy industrial applications.

The embedded EtherNet/IP interface makes the drive particularly appropriate for centralized automation systems.

The No-HIM configuration is well suited to applications where the PLC, DCS, SCADA system, or remote HMI is the primary operator interface.

The lack of dynamic braking should be considered carefully for high-inertia applications or machines requiring rapid deceleration.

For centrifugal pumps, fans, and other variable-torque applications, the drive can provide a large amount of capacity while allowing motor speed to follow process demand.

The model also provides a convenient midpoint in the 690 V PowerFlex 755 high-power range.

The 415 A model can be considered when less capacity is required, while the 500 A model can be considered when higher capacity is necessary.

For the same 460 A electrical class but with an enhanced local operator interface, the 20G1AJF460JN4NNNNN is the closely related configuration to consider.

53. Final Recommendation

For large industrial motor systems using a 690 VAC three-phase supply, the 20G1AJF460JN0NNNNN is a strong high-power PowerFlex 755 configuration when the motor current and application duty fall within its 460 A class.

It is particularly suitable for centralized automation systems where embedded EtherNet/IP is required and a local HIM is not necessary.

For variable-torque applications such as large centrifugal pumps, fans, blowers, and ventilation equipment, the 500 kW Light-Duty rating provides substantial capacity.

For general industrial machinery, the 450 kW Normal-Duty rating provides a practical selection point.

For more demanding machinery with higher overload requirements, the 375 kW Heavy-Duty rating should be used as the applicable reference.

The main engineering points to confirm before final selection are motor nameplate current, motor power, load torque, overload requirements, acceleration and deceleration time, regenerative energy, braking requirements, environmental conditions, motor cable length, grounding, EMC requirements, cabinet space, ventilation, and the plant’s control-system architecture.

In summary, the 20G1AJF460JN0NNNNN combines a 460 A current class, 690 VAC operation, 500/450/375 kW duty ratings, Frame 8 construction, IP54 / Type 12 protection, forced-air cooling, embedded EtherNet/IP, filtered input, installed CM jumper, AC input with precharge, and No-HIM centralized control in one high-power industrial drive configuration.

It is therefore well positioned for large-scale motor-control applications where reliability, network integration, high-power capacity, and standardized PowerFlex architecture are important engineering requirements.
