4. Product Introduction

The 20G1ABF265JN2NNNNN is intended for industrial installations where the motor power is too large for compact variable frequency drives and where a more substantial drive platform is required.

The PowerFlex 755 architecture provides a combination of high-power motor control, network integration, configurable control functions, and industrial-grade mechanical construction.

The 690 VAC rating makes this model particularly suitable for large motor systems commonly found in heavy industry.

The 265 A output rating places the unit in the high-current industrial drive category.

The drive can be integrated into automated production systems through its embedded EtherNet/IP capability, allowing a programmable controller or supervisory control system to exchange commands, references, status information, diagnostic information, and other operating data with the drive.

The JN2 configuration is especially useful when local access is important.

Unlike the JN0 version, which is supplied without a local HIM, the JN2 configuration provides an Enhanced LCD full numeric handheld/local HIM. This gives maintenance and commissioning personnel a practical interface for local drive setup and troubleshooting. 

---

5. Electrical Rating

The electrical rating of the 20G1ABF265JN2NNNNN can be summarized as follows:

Electrical Rating	Value
Model	20G1ABF265JN2NNNNN
Rated Voltage	690 VAC
Phase	3 Phase
Current	265 A
Low Duty	315 kW
Normal Duty	250 kW
Heavy Duty	200 kW
Approx. LD Horsepower	422 HP
Approx. ND Horsepower	335 HP
Approx. HD Horsepower	268 HP
Input Configuration	AC Input with Precharge
DC Terminals	None

The three duty ratings are important when matching the drive to a motor.

A drive should not be selected simply by comparing the motor’s nominal kW rating with the largest number in the drive’s catalog description.

The actual motor current, torque requirement, overload profile, acceleration requirement, operating cycle, and environmental conditions should also be considered.

---

6. Low Duty, Normal Duty and Heavy Duty

The 20G1ABF265JN2NNNNN provides three major power classifications.

Low Duty – 315 kW

The 315 kW Low Duty rating provides the highest nominal power capability.

Low Duty applications generally have less severe overload requirements and a comparatively moderate torque profile.

Typical examples may include certain centrifugal pumps and fans.

Normal Duty – 250 kW

The 250 kW Normal Duty rating is suitable for many conventional industrial motor applications.

This rating is particularly relevant when the motor operates continuously under a relatively stable load.

Heavy Duty – 200 kW

The 200 kW Heavy Duty rating is intended for applications with greater load demands.

Heavy Duty applications can involve higher starting torque, greater overload requirements, or more demanding acceleration and operating conditions.

The correct duty rating should always be determined from the actual application rather than simply from the motor’s nameplate horsepower.

---

7. 690 VAC Industrial Voltage Class

The 690 VAC rating is one of the most important characteristics of this model.

Large industrial plants frequently use higher-voltage motor systems for high-power machinery.

A 690 VAC motor system can be advantageous in large installations because higher voltage permits the required motor power to be transmitted at a lower current than would be required at a substantially lower voltage.

This can affect the selection of:

• Motor cables.
• Switchgear.
• MCC equipment.
• Transformers.
• Protective devices.
• Power distribution equipment.
• Motor starters and disconnects.

The 20G1ABF265JN2NNNNN is therefore much more appropriately viewed as a large industrial process drive than as a general-purpose small-machine inverter.

---

8. 265 A Current Rating

The 265 A current rating provides substantial capacity for large industrial motors.

The drive can be considered for applications such as:

• Large centrifugal pumps.
• Large process pumps.
• High-capacity fans.
• Large blowers.
• Heavy conveyors.
• Crushers.
• Mining equipment.
• Cement machinery.
• Material-handling equipment.
• Large process machinery.

When selecting a motor, the actual motor full-load current should be checked against the drive rating.

The motor’s kW value alone is not enough to determine compatibility.

---

9. Frame 8 Construction

The drive uses a Frame 8 construction.

Frame 8 is designed for high-power applications and therefore has a considerably larger physical footprint than compact PowerFlex drives.

The approximate equipment envelope is:

Mechanical Characteristic	Approximate Value
Model	20G1ABF265JN2NNNNN
Frame	Frame 8
Height	~2100 mm
Width	~610 mm
Depth	~600 mm
Overall Size	~2100 × 610 × 600 mm
Approx. Weight	~634 kg
Mechanical Style	600 mm Deep MCC Style
Cooling	Forced Air

These figures should be treated as preliminary engineering values.

The final installation should use the dimensional documentation associated with the actual drive configuration.

---

10. Dimensions and Weight

The 20G1ABF265JN2NNNNN is a large industrial drive.

For preliminary equipment-layout purposes, an approximate physical envelope of:

2100 mm × 610 mm × 600 mm

can be used.

The approximate complete-drive weight is:

634 kg

This weight is substantially different from some small weights occasionally associated with this catalog number in commercial databases.

Such very small values can represent packaging, subcomponents, or incorrect database associations rather than the complete Frame 8 drive.

For lifting calculations, transportation, floor loading, structural design, or cabinet engineering, the actual equipment documentation should always take precedence.

---

11. Air-Cooled Design

The 20G1ABF265JN2NNNNN uses an air-cooled / forced-air thermal design.

A drive operating at this power level generates considerable heat.

The cooling system is therefore an important part of the equipment design.

The air-cooled architecture has several practical advantages.

It does not require a dedicated liquid-cooling loop.

There is no external coolant pump required for normal drive cooling.

There is no separate liquid reservoir.

There is no external heat-exchanger circuit dedicated to the drive.

This makes the cooling arrangement comparatively straightforward for large industrial installations.

However, the electrical room or enclosure must provide suitable ventilation.

Hot exhaust air must not be allowed to circulate back into the drive intake.

---

12. AC Input With Precharge

The 20G1ABF265JN2NNNNN uses an AC input with precharge.

A high-power drive contains substantial DC-bus capacitance.

When the equipment is energized, the capacitors need to be charged.

Without appropriate control, the initial charging current could be excessive.

The precharge circuit allows the DC bus to charge in a controlled manner.

This is an important feature for a high-power drive of this size.

---

13. No DC Terminals

The catalog configuration specifies:

No DC terminals

This is important when considering special system architectures.

The model should not automatically be treated as a universal common-DC-bus drive.

Applications involving:

• Shared DC buses.
• External DC supplies.
• Regenerative DC systems.
• Specialized braking arrangements.
• Multi-drive DC architectures.

require separate engineering evaluation.

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

---

14. Filtered Configuration

The drive is supplied with a filtered configuration.

Variable frequency drives use high-speed semiconductor switching.

This switching creates high-frequency electrical components.

Filtering helps manage electromagnetic interference and supports the overall EMC performance of the installation.

Good EMC performance still depends on the complete system.

Important installation factors include:

• Motor cable construction.
• Shielding.
• Grounding.
• Cabinet bonding.
• Power/control cable separation.
• Network cable routing.
• Motor-frame grounding.
• Cable length.

The integrated filter should therefore be considered one part of the complete EMC design.

---

15. CM Jumper Installed

The JN2 configuration specifies:

CM Jumper Installed

This is an important distinction from the older AN2 configuration.

A simplified comparison is:

Configuration	CM Jumper
Older AN2	Removed
Current JN2	Installed

When replacing an older AN-series drive with a J-series drive, engineers should review the grounding and EMC arrangement.

The difference is not merely a cosmetic catalog-number change.

---

16. Dynamic Braking

The standard configuration specifies:

Dynamic Braking: None

This means that dynamic braking is not included in the standard catalog configuration.

For many applications, this is perfectly acceptable.

Examples include:

• Centrifugal pumps.
• Large fans.
• Blowers.
• Certain continuous conveyors.
• Applications where controlled stopping is sufficient.

Applications with large rotating inertia or rapid stopping requirements may require additional braking analysis.

Potential examples include:

• Crushers.
• Centrifuges.
• High-inertia conveyors.
• Large mixers.
• Hoisting systems.
• Rapid-cycle equipment.

The standard 20G1ABF265JN2NNNNN should therefore not be assumed to provide dynamic braking simply because it is a high-power drive.

---

17. Enhanced LCD Full Numeric Handheld / Local HIM

The JN2 configuration is particularly attractive because it includes an Enhanced LCD full numeric handheld/local HIM.

This is one of the principal differences between the JN2 and JN0 versions.

Model	HIM Configuration
20G1ABF265JN0NNNNN	Blank / No HIM
20G1ABF265JN2NNNNN	Enhanced LCD Full Numeric Handheld / Local HIM
20G1ABF265JN4NNNNN	Enhanced LCD Full Numeric Door-Mounted HIM

The JN2 configuration is therefore a good choice when local access is important but a permanent door-mounted operator interface is not required.

---

18. Advantages of the Local HIM

The local HIM can be particularly useful during:

• Initial commissioning.
• Motor setup.
• Parameter configuration.
• Troubleshooting.
• Fault investigation.
• Maintenance.
• Local status checking.
• Drive diagnostics.
• Startup testing.
• Service work.

A technician can work directly at the drive without relying entirely on a remote HMI or PLC interface.

This can significantly simplify maintenance work in a large electrical room.

---

19. Embedded EtherNet/IP

The drive incorporates embedded EtherNet/IP.

This allows the drive to become part of a networked automation architecture.

Typical information exchanged with the control system may include:

Data	Typical Function
Start Command	Motor start control
Stop Command	Motor stop control
Speed Reference	Desired motor speed
Actual Speed	Motor-speed monitoring
Output Frequency	Drive operating frequency
Output Current	Load monitoring
Drive Status	Operating-state monitoring
Fault Status	Fault indication
Warning Status	Warning indication
Diagnostic Information	Maintenance
Command Feedback	Control confirmation

This makes the model particularly suitable for centralized industrial automation.

---

20. Typical Automation Architecture

A typical installation could be organized as:

Potential applications include:

• Belt conveyors.
• Bucket elevators.
• Feed systems.
• Bulk-material transport.
• Transfer conveyors.
• Processing conveyors.
• Storage systems.

The local HIM is useful during maintenance, while EtherNet/IP provides the centralized control path.

---

The drive can also be considered for large process machines.

Examples include:

• Large mixers.
• Agitators.
• Rotating process machinery.
• Large production equipment.
• Material-processing machinery.

This can reduce troubleshooting time.

For example, during commissioning, the technician can verify:

• Drive status.
• Parameter settings.
• Motor configuration.
• Operating condition.
• Fault information.
• Speed reference.
• Actual operating data.

This is particularly useful for large installations where the drive may be located some distance from the operator station.

and approximately:

634 kg

installation planning should be completed before equipment delivery.

Consider:

• Door dimensions.
• Transportation route.
• Crane capacity.
• Forklift capacity.
• Floor loading.
• Equipment access.
• Cable routing.
• Service clearance.
• Ventilation.
• Maintenance access.
• Electrical-room layout.

The final dimensional drawing should always be used for detailed engineering.

---

53. Electrical Installation Considerations

The electrical installation should consider:

• 690 VAC supply.
• Appropriate upstream protection.
• Grounding.
• Motor feeder design.
• Motor cable selection.
• EMC requirements.
• Cable routing.
• Control wiring.
• Network wiring.
• Cabinet bonding.
• Thermal management.

The high-voltage and high-current nature of the equipment means that installation should be performed by appropriately qualified personnel.

---

54. Environmental Considerations

The drive uses a Type 1 / IP20 configuration.

It is therefore intended for a protected industrial environment rather than direct exposure to weather or washdown conditions.

The installation should provide protection from:

• Direct water.
• Condensation.
• Excessive humidity.
• Conductive dust.
• Corrosive contamination.
• Excessive ambient temperature.
• Other environmental conditions outside the drive’s specified operating range.

59. Final Summary

The Allen-Bradley 20G1ABF265JN2NNNNN is a high-power PowerFlex 755 AC variable frequency drive belonging to the PowerFlex 750-Series.

Its principal electrical characteristics are 690 VAC, three-phase, 265 A, with ratings of approximately 315 kW Low Duty, 250 kW Normal Duty, and 200 kW Heavy Duty. 

The drive uses a Frame 8, 600 mm deep MCC-style mechanical construction and is designed for large industrial motor applications.

The approximate physical envelope is 2100 × 610 × 600 mm, with an approximate equipment weight of 634 kg.

One of the most important features of the JN2 configuration is its Enhanced LCD full numeric handheld/local HIM.

This makes the model particularly attractive for applications where maintenance technicians need direct access to the drive while the machine is also integrated into a centralized PLC and EtherNet/IP control system.

The combination of local access and network control provides a practical balance between centralized automation and field-level maintenance.

The drive is especially suitable for large pumps, fans, blowers, conveyors, mining machinery, crushers, cement equipment, water and wastewater systems, material-handling equipment, and large process machinery.

For a fully centralized system where local access is not required, the 20G1ABF265JN0NNNNN is the closest alternative.

For permanent local operator access, the 20G1ABF265JN4NNNNN is another logical choice.

Where greater current capacity is required, the 20G1ABF330JN0NNNNN, 20G1ABF370JN0NNNNN, and 20G1ABF415JN0NNNNN provide progressively larger alternatives within the same high-power 690 VAC PowerFlex 755 family. The existence of these closely related configurations is reflected in the PowerFlex 755 catalog listings. 

For broader motor-control requirements, smaller PowerFlex 523 and PowerFlex 525 models are more appropriate for compact machinery, while other PowerFlex 755 models provide substantially greater power and current capability.

Overall, the 20G1ABF265JN2NNNNN is best suited to installations that require high-power 690 VAC motor control, 265 A output capability, networked automation, local commissioning access, forced-air cooling, and a robust Frame 8 industrial platform.
