---

4. Important Note About Dimensions and Weight

The 20G1ABF265JN0NNNNN is a very large Frame 8 drive.

For engineering layout purposes, a practical preliminary dimensional envelope is approximately:

2100 mm high × 610 mm wide × 600 mm deep

A practical preliminary weight value is approximately:

634 kg

These values should be regarded as approximate equipment-level figures for planning purposes.

Some commercial product listings incorrectly associate very small weights with this catalog number. For example, a listing gives a weight of only 14.51 kg, which is clearly inconsistent with a complete Frame 8, 600 mm deep MCC-style, 265 A high-power packaged drive. That type of value should not be used as the whole-drive installation weight.

For final mechanical design, transportation, lifting, floor-loading calculations, or cabinet fabrication, the actual dimensional drawing and equipment configuration should be used.

---

5. Electrical Rating

The 20G1ABF265JN0NNNNN is a 690 VAC three-phase drive with a rated output current of 265 A.

Its principal duty ratings are:

Duty Classification	Power Rating	Approx. HP Equivalent
Low Duty	315 kW	~422 HP
Normal Duty	250 kW	~335 HP
Heavy Duty	200 kW	~268 HP

The difference between Low Duty, Normal Duty, and Heavy Duty is important when selecting a drive.

A motor should not be selected solely by comparing horsepower.

The actual motor current, torque requirements, overload requirements, acceleration profile, operating cycle, ambient conditions, and load characteristics must also be evaluated.

The catalog description specifically identifies 315 kW LD, 250 kW ND, and 200 kW HD for this model. 

---

6. 690 VAC High-Voltage Industrial Architecture

One of the defining features of the 20G1ABF265JN0NNNNN is its 690 VAC voltage class.

This makes it particularly relevant to large industrial motor systems.

Higher-voltage motor systems can provide advantages in large installations because the current required for a given power level can be lower than in an equivalent lower-voltage system.

This can influence the design of:

• Motor feeders.
• Cable systems.
• Switchgear.
• Transformers.
• MCC equipment.
• Protection equipment.
• Electrical distribution.

For large industrial plants, the 690 VAC class can therefore be an important part of the overall electrical architecture.

---

7. 265 A Output Current

The 265 A output rating gives this drive substantial motor-control capacity.

It is intended for large motors that are well beyond the practical range of compact machine-level variable frequency drives.

Typical applications include:

• Large pumps.
• Large fans.
• Large blowers.
• Heavy conveyors.
• Crushers.
• Mining equipment.
• Cement machinery.
• Bulk-material handling.
• Process machinery.
• Large rotating equipment.

The 265 A rating should always be compared against the motor’s actual full-load current.

A motor nameplate showing a particular kW rating does not by itself guarantee that the motor and drive are correctly matched.

---

8. Frame 8 Construction

The 20G1ABF265JN0NNNNN uses a Frame 8 platform.

Frame 8 is designed for high-power applications and has a substantially larger mechanical footprint than compact VFDs.

The approximate physical envelope is:

Mechanical Parameter	Approximate Value
Model	20G1ABF265JN0NNNNN
Frame	Frame 8
Height	~2100 mm
Width	~610 mm
Depth	~600 mm
Overall Dimensions	~2100 × 610 × 600 mm
Approx. Weight	~634 kg
Mechanical Style	600 mm Deep MCC Style
Cooling	Forced Air
Enclosure	Type 1 / IP20

This size and weight should be considered during the initial plant-layout stage.

A drive of this size requires suitable access for:

• Transportation.
• Lifting.
• Installation.
• Cable connection.
• Inspection.
• Cooling.
• Maintenance.
• Component replacement.

---

9. Air-Cooled Design

The 20G1ABF265JN0NNNNN is an air-cooled PowerFlex 755 drive.

At 265 A output current, the drive’s power semiconductors and other electrical components generate significant heat.

Forced-air cooling is used to remove this heat.

The air-cooled architecture provides several practical advantages.

There is no need for a dedicated liquid-cooling loop.

There is no external coolant pump.

There is no coolant reservoir.

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

This makes the thermal system relatively straightforward for a large industrial installation.

However, adequate ventilation remains essential.

The electrical room or enclosure must provide suitable airflow and must prevent excessive recirculation of hot air.

---

10. AC Input With Precharge

The drive uses an AC input with precharge.

This means the drive’s internal DC bus is charged in a controlled manner when the equipment is energized.

A large variable frequency drive contains substantial DC-bus capacitance.

Applying power directly to an uncharged capacitor bank could result in a very large inrush current.

The precharge function limits this initial charging current and allows the DC bus to reach its operating condition in a controlled sequence.

For a 265 A high-power drive, this is an important part of the input architecture.

---

11. No DC Terminals

The standard configuration specifies:

No DC terminals

This is important when evaluating applications involving:

• Common DC buses.
• External DC sources.
• Regenerative energy systems.
• Shared DC-bus architectures.
• Specialized braking arrangements.

The standard 20G1ABF265JN0NNNNN should therefore be evaluated as an AC-input drive rather than assumed to be a general-purpose common-DC-bus unit.

If the project requires a specialized DC-bus architecture, the complete configuration must be reviewed.

---

12. Filtered Configuration

The drive is supplied in a filtered configuration.

High-speed switching in a VFD produces high-frequency electrical components.

The filtering arrangement helps control these electrical disturbances and supports electromagnetic compatibility.

However, proper EMC performance depends on the complete installation.

Important factors include:

• Motor cable selection.
• Cable shielding.
• Grounding.
• Cabinet bonding.
• Control wiring.
• Network cable routing.
• Separation between power and control cables.
• Motor-frame grounding.
• Proper installation practices.

The integrated filtering should therefore be viewed as one part of the overall EMC design.

---

13. CM Jumper Installed

The JN0 configuration uses a CM jumper installed arrangement.

This is an important distinction compared with the older AN0 version of the same power rating.

The basic comparison is:

Configuration	CM Jumper
Older AN0 configuration	Removed
Current JN0 configuration	Installed

This distinction can influence common-mode behavior and grounding characteristics.

When replacing an older AN-series drive with a J-series unit, the complete grounding arrangement and EMC design should be reviewed.

The catalog number should not be treated as the only consideration during a replacement project.

---

14. 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 acceptable.

Examples include:

• Large centrifugal pumps.
• Many large fans.
• Blowers.
• Processes where gradual deceleration is acceptable.

However, applications with high inertia or rapid stopping requirements require additional consideration.

Potential examples include:

• High-inertia conveyors.
• Crushers.
• Centrifuges.
• Large mixers.
• Hoisting equipment.
• Rapid-cycle machines.
• Certain material-handling systems.

If substantial regenerative energy is produced during deceleration, an appropriate braking strategy should be evaluated separately.

---

15. Blank / No HIM

The 20G1ABF265JN0NNNNN is configured as:

Blank / No HIM

HIM means Human Interface Module.

The absence of a local HIM is often useful in a centralized automation system.

Instead of placing an operator keypad directly on the drive, the plant can use:

• PLC control.
• HMI control.
• SCADA.
• EtherNet/IP.
• Centralized diagnostic software.

This is especially useful when the drive is installed in an electrical room and operators work from a remote control room.

---

16. Embedded EtherNet/IP

Embedded EtherNet/IP is one of the most useful features of the configuration.

The drive can be integrated into a plant-wide industrial network.

Typical control and monitoring information can include:

Information	Typical Function
Start Command	Starts motor operation
Stop Command	Stops motor operation
Speed Reference	Sets desired motor speed
Actual Speed	Monitors motor speed
Output Frequency	Monitors drive frequency
Output Current	Monitors motor load
Drive Status	Indicates operating condition
Fault Status	Identifies faults
Warning Status	Identifies warnings
Diagnostic Data	Supports troubleshooting
Command Status	Confirms command execution

This makes the drive suitable for automated industrial systems where many motors are controlled from a central PLC.

---

17. Typical Control Architecture

A typical system can be structured as:

Plant PLC

↓

EtherNet/IP Network

↓

PowerFlex 755

↓

Large Industrial Motor

↓

Mechanical Process

This architecture eliminates the need for every control function to be physically located next to the drive.

The drive can remain inside a dedicated electrical room while the operator controls the process from a central HMI.

This is particularly useful in large industrial plants with multiple high-power motors.

---

18. Main Product Applications

18.1 Large Pump Systems

Large pumps are one of the most practical applications for this drive.

Typical applications include:

• Water supply.
• Wastewater systems.
• Industrial process pumps.
• Cooling-water circulation.
• Mining dewatering.
• Utility pumping.
• Process circulation.
• Large-scale fluid-transfer systems.

The drive can regulate motor speed according to the required flow or pressure.

This can provide better process control than operating a fixed-speed motor continuously at full speed.

---

19. Large Fan Systems

Large industrial fans can consume significant amounts of power.

Typical applications include:

• Furnace ventilation.
• Industrial exhaust.
• Combustion air.
• Dust collection.
• Process cooling.
• Cement plants.
• Metals processing.
• Large building or tunnel ventilation.

The drive can adjust fan speed according to actual process requirements.

Controlled acceleration can also reduce mechanical stress during startup.

---

20. Large Blowers

Large blowers are another suitable application.

Potential applications include:

• Wastewater aeration.
• Industrial air systems.
• Process gas movement.
• Combustion systems.
• Pneumatic material handling.
• Large ventilation systems.

The ability to vary motor speed allows blower output to be matched to process requirements.

---

21. Conveyor Systems

Large conveyors often have high inertia and substantial starting torque requirements.

The drive can provide controlled acceleration rather than immediately applying full operating speed.

This can reduce mechanical shock on:

• Conveyor belts.
• Gearboxes.
• Couplings.
• Shafts.
• Bearings.
• Drive pulleys.

For long conveyors, networked drive control can also assist with coordination between multiple conveyor sections.

---

22. Mining Equipment

Mining machinery frequently requires high-power motor control.

Typical applications include:

• Ore conveyors.
• Crushers.
• Large pumps.
• Ventilation fans.
• Material-handling equipment.

The 690 VAC architecture is well suited to large industrial electrical systems.

EtherNet/IP integration also allows the drive to become part of a larger mining automation system.

---

23. Cement and Aggregate Equipment

Cement and aggregate facilities contain numerous large motors.

The drive can be applied to:

• Crushers.
• Conveyors.
• Large fans.
• Blowers.
• Pumps.
• Feeders.
• Material-transfer systems.
• Process equipment.

The high-power architecture is particularly appropriate where motor sizes exceed the range of compact VFDs.

---

24. Crusher Applications

Crushers can impose significant starting and mechanical demands.

A variable frequency drive can provide a controlled acceleration profile.

Potential benefits include:

• Controlled startup.
• Reduced mechanical shock.
• Adjustable operating speed.
• Better process coordination.
• Centralized diagnostics.
• Network monitoring.

However, crusher applications should receive particular attention regarding braking and deceleration.

The standard 20G1ABF265JN0NNNNN configuration does not include dynamic braking.

---

25. Material-Handling Applications

Large material-handling systems can also benefit from variable-speed motor control.

Examples include:

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

The drive can provide controlled startup and adjustable operating speed while allowing the automation system to monitor the drive remotely.

---

26. Process Machinery

The drive can also be used with large process machinery.

Potential applications include:

• Large mixers.
• Agitators.
• Rotating processing equipment.
• Large production machinery.
• Material-processing systems.
• Industrial ventilation equipment.

The final selection depends on the motor current, torque profile, speed range, acceleration requirements, and process duty.

---

It allows the drive to participate in higher-voltage motor distribution systems.

---

27.6 Frame 8 High-Power Construction

The Frame 8 architecture provides the physical and thermal platform necessary for high-power applications.

---

27.7 Embedded EtherNet/IP

Embedded EtherNet/IP makes centralized control and monitoring practical.

---

27.8 No-HIM Architecture

The no-HIM configuration is ideal for systems where operator control is performed through a centralized HMI or SCADA system.

---

27.9 Air Cooling

The forced-air architecture avoids the complexity of an external liquid-cooling system.

---

27.10 Filtered Configuration

The filtered configuration supports EMC-conscious industrial installations.

---

30. Environmental and Installation Characteristics

The drive is intended for a controlled industrial environment.

A suitable installation should provide:

• Adequate ventilation.
• Suitable ambient temperature.
• Protection from direct water.
• Protection from excessive condensation.
• Appropriate grounding.
• Appropriate cable routing.
• Adequate service clearance.
• Suitable floor loading.
• Correct power-cable installation.
• Correct motor-cable installation.
• Proper network-cable routing.

The Type 1 / IP20 configuration is not a weatherproof or washdown enclosure.

It should therefore normally be installed in an appropriate electrical room, MCC area, or protected industrial enclosure.

---

31. Motor Selection Considerations

Before selecting a motor for this drive, engineers should review the following:

Selection Factor	Importance
Motor Voltage	Critical
Motor Full-Load Current	Critical
Motor Power	Critical
Motor Frequency	Critical
Duty Classification	Critical
Overload Requirement	Critical
Acceleration Time	High
Deceleration Time	High
Load Inertia	High
Braking Requirement	High
Motor Cable Length	High
Ambient Temperature	High
Installation Altitude	Medium to High
EMC Requirements	High
Network Requirements	High

The motor’s actual nameplate current should be compared with the 265 A drive rating.

The drive’s 250 kW Normal Duty rating should not be interpreted as meaning that every 250 kW motor is automatically suitable.

The complete operating profile must be considered.

---

32. Low Duty, Normal Duty and Heavy Duty

The three duty categories provide flexibility.

Low Duty – 315 kW

The 315 kW Low Duty rating is appropriate where the load profile is comparatively less demanding.

Normal Duty – 250 kW

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

Heavy Duty – 200 kW

The 200 kW Heavy Duty rating applies where the load places greater thermal or overload demands on the drive.

The correct rating should be selected according to the actual load characteristics rather than simply choosing the largest available power number.

---

33. Five Recommended Same-Series or Closely Related Models

The following models are closely related to the subject model within the 690 VAC PowerFlex 755 high-power range.

Model	Voltage	Current	LD Rating	ND Rating	HD Rating	HIM	CM Jumper	Approx. Dimensions	Approx. Weight
20G1ABF265JN0NNNNN	690 VAC	265 A	315 kW	250 kW	200 kW	No HIM	Installed	~2100 × 610 × 600 mm	~634 kg
20G1ABF265JN2NNNNN	690 VAC	265 A	315 kW	250 kW	200 kW	Handheld / Local LCD	Installed	~2100 × 610 × 600 mm	~634 kg

20G1ABF370JN0NNNNN	690 VAC	370 A	~400 kW	~355 kW	~300 kW	No HIM	Installed	~2100 × 610 × 600 mm	~634 kg

The 265 A, 330 A, and 370 A variants are part of the same 690 VAC PowerFlex 755 model group, while the JN2 and JN4 versions provide different local-interface configurations. 

---

34. Comparison of the Three 265 A Configurations

Model	HIM	CM Jumper	Basic Purpose
20G1ABF265AN0NNNNN	No HIM	Removed	Older AN-series configuration
20G1ABF265JN0NNNNN	No HIM	Installed	Current no-HIM configuration
20G1ABF265JN2NNNNN	Handheld / Local LCD	Installed	Local commissioning and maintenance
20G1ABF265JN4NNNNN	Door-Mounted LCD	Installed	Local operator access

This comparison shows why the 20G1ABF265JN0NNNNN is particularly useful for centralized control applications.

The JN0 configuration retains the high-power electrical rating while omitting the local HIM.

---

35. 20G1ABF265AN0NNNNN vs. 20G1ABF265JN0NNNNN

Approx. Dimensions	~2100 × 610 × 600 mm	~2100 × 610 × 600 mm
Approx. Weight	~634 kg	~634 kg

The principal distinction is the CM jumper configuration.

The JN0 configuration is the newer configuration with the CM jumper installed.

For a replacement project, the grounding and EMC characteristics should be reviewed before installation.

---

36. Why the JN0 Configuration Is Attractive

The JN0 configuration is particularly well suited to centralized automation.

The drive does not need to be physically operated from its front panel.

Instead, the plant control system can manage the drive through EtherNet/IP.

This is useful when:

• The drive is installed in an electrical room.
• The operator works from a control room.
• Several drives are managed by one PLC.
• The plant uses centralized HMI stations.
• Local keypad operation is not required.

The result is a clean architecture with centralized monitoring and control.

---

37. Local HIM Alternative

If technicians need direct access to the drive, the 20G1ABF265JN2NNNNN can be considered.

The JN2 configuration maintains the same basic 265 A, 690 VAC power class while adding a local handheld/local LCD interface.

This can be useful during:

• Commissioning.
• Startup.
• Troubleshooting.
• Maintenance.
• Parameter adjustment.

For systems where operators require direct access at the equipment, the JN4 configuration can also be considered.

---

38. Larger Current Alternatives

When the 265 A rating is insufficient, larger models in the same family can be considered.

The 20G1ABF330JN0NNNNN provides a higher current class.

The 20G1ABF370JN0NNNNN provides another step upward in current and power capability.

This gives engineers a practical way to maintain the same general drive architecture while increasing motor capacity.

20G1ABC650JN4NNNNN	PowerFlex 755	480 VAC class	~650 A	Very large industrial equipment	~2100 × 610 × 600 mm	~600+ kg

These models represent different points within the same brand’s AC-drive portfolio.

The PowerFlex 523 and PowerFlex 525 are much smaller and are intended for compact industrial machinery.

The PowerFlex 755 configurations are intended for substantially larger motor applications.
