4. Output Current Ratings

The 20G1ALE395JN0NNNNN is a multi-duty industrial drive.

Its published ratings allow it to be applied to different load categories.

Duty	Continuous Output Current	Short-Time Overload	Approx. Motor Rating
Light Duty	395 A	435 A / 1 min	450 HP
Normal Duty	355 A	391 A / 1 min; higher short-time overload capability	400 HP
Heavy Duty	295 A	443 A / 1 min; higher short-time overload capability	350 HP

The distinction between LD, ND, and HD is important.

A drive should not simply be selected according to the highest horsepower number shown in a product description.

The motor’s actual full-load current, required overload capability, starting torque, acceleration profile, operating cycle, and load characteristics should be checked before final selection.

---

5. Light Duty Rating

In Light Duty operation, the drive provides its highest continuous current rating.

For this model, the Light Duty rating is:

395 A continuous output current

with an approximate motor rating of:

450 HP

Light Duty operation is generally appropriate for applications with relatively moderate overload requirements and smoother torque characteristics.

Typical examples can include large centrifugal pumps, large fans, and certain blower applications.

---

6. Normal Duty Rating

The Normal Duty rating is approximately:

355 A continuous output current

with an approximate motor rating of:

400 HP

Normal Duty operation provides a different balance between motor power and overload capability.

This rating can be relevant to general industrial machinery where the load is more demanding than a typical variable-torque application but does not require the highest Heavy Duty operating profile.

---

7. Heavy Duty Rating

The Heavy Duty rating is approximately:

295 A continuous output current

with an approximate motor rating of:

350 HP

Heavy Duty operation is intended for applications where higher torque demand and overload performance are important.

Examples can include certain conveyors, heavy process machinery, mixers, material-handling equipment, and machinery with demanding acceleration requirements.

---

10. Product Introduction

The PowerFlex 755 is a high-performance industrial drive platform designed for large motor-driven machinery.

The 20G1ALE395JN0NNNNN combines a high-current power section with embedded industrial network communication.

Instead of operating a large motor directly from a fixed-frequency AC supply, the drive can regulate the motor’s operating speed according to the needs of the machine.

This is useful in applications where process demand changes during operation.

For example, a large pump may not need to run at full speed continuously.

A large fan may need different airflow at different production conditions.

A conveyor may require controlled acceleration rather than an immediate full-speed start.

A process machine may need a specific speed profile during different stages of operation.

The PowerFlex 755 platform is intended to handle these types of requirements.

---

11. Main Product Functions

Variable-Speed Motor Control

The fundamental function of the drive is to provide adjustable-speed operation for a three-phase AC motor.

Motor speed can be changed by controlling the output frequency and voltage.

This allows the mechanical equipment to operate according to the actual production or process requirements.

Controlled Acceleration

The drive can provide programmed acceleration instead of connecting the motor directly to full line power.

This can help reduce mechanical shock and provide smoother machine startup.

Controlled Deceleration

The drive can also provide controlled deceleration.

This is useful for conveyors, process machinery, fans, pumps, and other systems where an uncontrolled stop may cause mechanical or process problems.

Torque Control

The PowerFlex 755 platform supports motor-control functions suitable for applications requiring controlled torque.

This is useful where the load changes during operation.

Networked Control

The embedded EtherNet/IP interface allows the drive to be integrated into an industrial automation network.

This can allow commands, references, status information, and diagnostic information to be exchanged between the drive and the control system.

---

12. Embedded EtherNet/IP

The 20G1ALE395JN0NNNNN includes embedded EtherNet/IP communication.

This is one of the most useful characteristics of this configuration for modern industrial automation systems.

A typical system can be arranged as:

PLC → EtherNet/IP Network → PowerFlex 755 → AC Motor → Mechanical Load

The drive can exchange operating information with the control system.

Typical network information can include:

Data Type	Typical Function
Start Command	Starts motor operation
Stop Command	Stops motor operation
Speed Reference	Sets required speed
Frequency Reference	Sets output frequency
Output Frequency	Reports actual operating frequency
Output Current	Reports motor current
Drive Status	Reports operating condition
Fault Status	Reports faults
Alarm Status	Reports warnings
Control Word	Sends operating commands
Status Word	Returns drive status
Diagnostic Information	Supports troubleshooting

This makes the drive particularly useful in automated production environments.

---

13. CM Jumper Configuration

A key difference between the 20G1ALE395JN0NNNNN and the closely related 20G1ALE395AN0NNNNN is the CM jumper configuration.

For the J configuration, the CM jumper is specified as:

CM Jumper Installed — Preferred

The complete configuration information identifies the unit as filtered with the CM jumper installed.

This detail should not be ignored when replacing an existing drive.

Two drives can have almost identical current and horsepower ratings but still have different electrical configurations.

For replacement work, the complete catalog number should therefore be checked rather than matching only the series and amp rating.

---

14. Difference Between 20G1ALE395JN0NNNNN and 20G1ALE395AN0NNNNN

---

21. Physical Dimensions and Weight

The model is a large Frame 8, 800 mm deep MCC-style drive configuration.

For this type of equipment, physical dimensions can depend on the complete cabinet arrangement, installation configuration, and associated components.

The available product information identifies the enclosure as Type 1 / IP20 with an 800 mm deep MCC-style construction.

For weight, a listed unit reference gives approximately 185 lb, which is about 84 kg. This figure should be treated as a product/unit reference rather than a guaranteed shipping weight for every complete cabinet arrangement.

Physical Parameter	Specification / Reference
Model	20G1ALE395JN0NNNNN
Frame	Frame 8
Enclosure	Type 1 / IP20
Cabinet Style	MCC Style
Cabinet Depth	800 mm
Approx. Unit Weight	84 kg
Weight Reference	Approximately 185 lb
Overall Dimensions	Large Frame 8 MCC-style arrangement
Installation	Vertical industrial cabinet / MCC
Cooling	Forced Air
Service Space	Required according to installation design

For cabinet fabrication, transportation, lifting, foundation design, or final mechanical engineering, the exact mechanical drawing for the configured unit should be used.

The 800 mm depth is a particularly important consideration when planning the electrical room or MCC lineup.

---

22. Installation Requirements

A high-power drive such as the 20G1ALE395JN0NNNNN requires careful installation planning.

Important considerations include:

• Incoming voltage
• Incoming current capacity
• Short-circuit conditions
• Protective devices
• Grounding
• Motor cable size
• Motor cable routing
• Motor insulation
• Cabinet ventilation
• Ambient temperature
• Altitude
• Service clearance
• Control wiring
• Network wiring
• Heat dissipation
• Maintenance access

The drive should be installed in a suitable industrial electrical environment.

Because the enclosure is Type 1 / IP20, the equipment should not be treated as a weatherproof or washdown enclosure.

---

23. Cooling and Heat Management

The 20G1ALE395JN0NNNNN uses forced-air cooling.

At this power level, heat management becomes an important part of system design.

The actual heat generated depends on:

• Motor load
• Output current
• Switching conditions
• Ambient temperature
• Motor operating speed
• Drive operating cycle
• Cabinet arrangement
• Installation altitude
• Drive configuration

The cabinet should provide adequate airflow and should avoid recirculating hot exhaust air back into the cooling inlet.

Air filters and cooling fans should also be included in the maintenance plan.

---

24. Maintenance Considerations

Regular maintenance can include inspection of:

• Cooling fans
• Air filters
• Cabinet ventilation
• Electrical connections
• Power terminals
• Grounding connections
• Control wiring
• Network connections
• Drive alarms
• Fault history
• Motor cables
• Cabinet cleanliness

The forced-air cooling system is particularly important.

Dust accumulation around air filters or cooling passages can reduce airflow and increase operating temperature.

For large industrial drives, planned inspection is preferable to waiting for a cooling-related fault.

---

25. Network Integration Advantages

The integrated EtherNet/IP interface provides several practical benefits in an automated system.

The drive can be connected to the plant network and controlled from a central automation system.

A typical architecture may include:

Operator HMI → PLC → Industrial Ethernet Network → PowerFlex 755 → Motor

This architecture allows motor operation to become part of the overall machine-control strategy.

For example, the PLC can determine the required motor speed based on process conditions, send the reference to the drive, and monitor drive status.

The operator can then view drive information through the HMI.

---

26. Process Control Applications

The model is particularly useful when motor speed is part of the process itself.

Examples include:

Flow Control

Pump speed can be adjusted according to required flow.

Pressure Control

Pump speed can be changed according to system pressure.

Airflow Control

Fan speed can be adjusted according to ventilation demand.

Conveyor Speed Control

Conveyor speed can be coordinated with production requirements.

Process Machine Speed

Motor speed can be adjusted according to different stages of a manufacturing process.

---

Large General Industrial Load	20G1ALE395JN0NNNNN	Balanced high-power capacity

These are application-oriented reference points rather than automatic replacement recommendations.

Final selection should be based on motor nameplate current and actual load characteristics.

---

31. Electrical Advantages

The 600 VAC three-phase configuration is suitable for large industrial motor systems.

Using a higher motor voltage for large power levels can allow the required motor power to be delivered at a lower current than would be required at a substantially lower motor voltage.

This is one reason high-voltage motor systems are common in larger industrial installations.

The 20G1ALE395JN0NNNNN is therefore suited to large electrical systems where substantial motor power is required.

---

32. Mechanical Advantages

The MCC-style construction makes the drive suitable for centralized electrical installations.

This is useful where several motor drives are installed together in a common electrical room or motor control center.

The 800 mm deep configuration should be taken into account during cabinet layout and electrical-room planning.

For large projects, sufficient space should also be allowed for:

• Cable entry
• Maintenance
• Cooling airflow
• Component access
• Network connections
• Power connections
• Removal of service components

---

33. Control Advantages

The drive provides more than simple speed adjustment.

It can become part of a complete machine-control system.

The control system can manage:

• Start
• Stop
• Speed
• Acceleration
• Deceleration
• Operating status
• Fault status
• Alarms
• Diagnostic information

This allows motor operation to be coordinated with the rest of the production process.

---

34. Maintenance Advantages

The PowerFlex 755 platform provides a structured approach to drive diagnostics and maintenance.

The drive can provide operating and fault information that can be integrated into a control system.

This can help maintenance personnel determine whether a problem is associated with:

• Motor operation
• Drive operation
• Control commands
• Network communication
• Overcurrent
• Overload
• Thermal conditions
• Other drive-related conditions

A well-designed networked drive system can therefore provide more information than a conventional standalone motor starter.

---

35. Replacement Considerations

When replacing a 20G1ALE395JN0NNNNN, the complete catalog number should be compared.

The following items are particularly important:

Item	Check

DC Terminals	None
Filtering	Filtered
CM Jumper	Installed
HIM	None
Physical Arrangement	Verify before replacement
Weight	Verify actual shipping/unit configuration

The CM jumper configuration is especially important because the J and A catalog configurations differ in this area.

---

36. Motor Compatibility

Before connecting a motor, check:

Motor Parameter	Required Check
Motor Voltage	Must match drive application
Motor Current	Must be within drive capability
Motor HP	Must match selected duty
Motor Frequency	Verify
Motor Speed	Verify
Motor Insulation	Verify for VFD operation
Motor Cable	Correct size and type

39. Detailed Product Positioning

The Allen-Bradley 20G1ALE395JN0NNNNN is a high-power PowerFlex 755 drive intended for industrial motor applications where the motor power level is substantially above the range normally handled by compact general-purpose drives.

Its 600 VAC three-phase input and Frame 8 power structure make it suitable for large industrial electrical systems.

The 395 A Light Duty rating provides a substantial amount of continuous output current, while the 355 A Normal Duty and 295 A Heavy Duty ratings provide different operating options according to the load profile.

The embedded EtherNet/IP interface is another important characteristic.

Rather than operating as a standalone motor controller, the drive can be integrated into an automated control system and exchange operational information with the rest of the machine or plant.

The forced-air cooling system and MCC-style physical arrangement are consistent with the requirements of high-power industrial equipment.

---

40. Final Product Description

The Allen-Bradley 20G1ALE395JN0NNNNN PowerFlex 755 AC Drive is a high-power three-phase variable frequency drive designed for large industrial motor applications.

The drive is rated for 600 VAC, uses a Frame 8 power structure, and provides a 395 A Light Duty output rating.

Its published motor ratings are approximately 450 HP for Light Duty, 400 HP for Normal Duty, and 350 HP for Heavy Duty.

The drive uses forced-air cooling and a Type 1 / IP20, 800 mm deep MCC-style enclosure.

It includes embedded EtherNet/IP, allowing integration with networked automation systems.

The stated configuration uses AC input with precharge, no external DC terminals, filtered input configuration, no dynamic braking, and no HIM.

One of the defining configuration details of this particular catalog number is the CM jumper installed configuration.

This makes the model distinct from closely related catalog numbers that use a different CM jumper configuration.

The drive is suitable for large pumps, fans, blowers, conveyors, compressors, process machinery, material-handling equipment, water systems, and other large motor-driven industrial equipment.

For physical planning, the unit belongs to the large Frame 8 MCC-style class and uses an approximately 800 mm deep cabinet arrangement.

A listed unit reference gives approximately 84 kg for the unit weight, while the final shipping or installed cabinet weight should be confirmed from the exact mechanical configuration.

The complete catalog number should always be retained when purchasing, replacing, or comparing the drive because configuration characters can change important electrical and mechanical characteristics.

In practical terms, the 20G1ALE395JN0NNNNN is a large-capacity, network-capable industrial drive intended to provide controlled speed, controlled acceleration and deceleration, motor-control functionality, and centralized automation integration for substantial three-phase AC motor loads.
