Model: 20G1ALE395AN0NNNNN

The Allen-Bradley 20G1ALE395AN0NNNNN is a high-power AC variable frequency drive from the PowerFlex 755 series, designed for demanding industrial motor-control applications where reliable speed regulation, torque control, network connectivity, and flexible drive configuration are required.

This model is intended for large three-phase AC motors and is particularly suitable for industrial machinery, pumps, fans, conveyors, compressors, process equipment, material handling systems, and other large motor-driven applications.

The drive is configured for a 600 VAC, three-phase input supply and belongs to the high-power Frame 8 class. Its published current ratings provide different operating levels for Light Duty, Normal Duty, and Heavy Duty applications, allowing the same drive platform to be applied to different motor-load requirements.

The model provides an integrated EtherNet/IP communication interface, making it suitable for modern industrial control systems where the drive needs to exchange operating commands, speed references, status information, diagnostic information, and other data with a plant control network.

The unit uses forced-air cooling and is designed in an industrial Type 1 / IP20 enclosure configuration. The configuration is associated with an 800 mm deep MCC-style installation arrangement, making it suitable for larger industrial electrical rooms, motor control centers, drive cabinets, and centralized motor-control installations.

4. Output Current Ratings

The 20G1ALE395AN0NNNNN provides different current capabilities depending on the selected operating duty.

Duty Rating	Continuous Output Current	Short-Time Rating	Typical Motor Rating
Light Duty (LD)	395 A	435 A for 1 min	450 HP
Normal Duty (ND)	355 A	391 A for 1 min; up to 533 A for 3 sec	400 HP
Heavy Duty (HD)	295 A	443 A for 1 min; up to 533 A for 3 sec	350 HP

The actual usable motor rating should always be selected according to the motor nameplate current, load profile, acceleration requirements, overload requirements, ambient conditions, installation method, and applicable drive configuration.

The current rating is especially important for large industrial motors because two motors with the same horsepower rating can have different full-load current requirements depending on motor efficiency, power factor, voltage, construction, and operating conditions.

For that reason, the motor’s nameplate current should be treated as a primary selection parameter, rather than selecting the drive from horsepower alone.

---

5. Motor Capacity

The model is designed for large 600 VAC three-phase motor applications.

Duty	Approximate Motor Capacity
Light Duty	450 HP
Normal Duty	400 HP
Heavy Duty	350 HP
Motor Voltage	Up to 600 VAC class
Motor Type	Three-phase AC motor
Control Application	Variable-speed industrial motor control

The different duty ratings allow the drive to be used with different types of loads.

A pump or fan with a relatively smooth torque requirement may use a different duty selection than a heavily loaded conveyor, crusher, mixer, compressor, or other application requiring substantial starting and accelerating torque.

---

6. Input Power Characteristics

The 20G1ALE395AN0NNNNN is configured for a 600 VAC three-phase AC input.

The input section incorporates a precharge arrangement, which is important in a high-power drive because the DC bus contains substantial energy storage. Precharge limits the initial charging current into the DC bus components during startup.

Number of Phases	3
Input Type	AC
Precharge	Included
Frequency	50/60 Hz class
DC Input Terminals	Not provided in the stated configuration

8. Product Introduction

The PowerFlex 755 is a high-performance industrial drive platform intended for applications in which the motor must operate at controlled variable speed rather than simply running at a fixed line frequency.

The 20G1ALE395AN0NNNNN combines high current capacity with networked control capability. Its integrated EtherNet/IP interface allows it to become part of a larger automation architecture instead of operating as an isolated motor controller.

In a typical installation, the drive can receive a start command and speed reference from a control system, regulate motor speed, monitor operating conditions, provide diagnostic information, and transmit status information back to the control system.

This makes the drive suitable for centralized industrial automation environments where motor-control information needs to be available to operators and maintenance personnel.

The Frame 8 design places the product in the high-power segment of the PowerFlex 755 family. It is intended for substantial motor loads and is commonly considered for large process and production equipment.

---

9. Main Functions

The 20G1ALE395AN0NNNNN is designed to provide a broad range of motor-control functions.

Variable Speed Control

The primary function is to control the speed of a three-phase AC motor by varying the frequency and voltage supplied to the motor.

This can allow machinery to operate at the speed required by the production process rather than continuously operating at full motor speed.

Acceleration and Deceleration Control

Programmable acceleration and deceleration profiles allow the motor to start and stop in a controlled manner.

This can reduce mechanical shock and help coordinate motor operation with conveyors, pumps, fans, and other equipment.

Torque Control

The PowerFlex 755 platform supports advanced motor-control functions suitable for applications where maintaining motor torque is important.

This is particularly useful for material handling, conveyors, hoists, process equipment, and other applications where load conditions can change significantly.

Networked Control

The integrated EtherNet/IP interface provides a convenient method for connecting the drive to an industrial control network.

Depending on the control architecture, the drive can exchange commands, references, status data, feedback, alarms, and diagnostic information with the automation system.

Diagnostic Functions

Drive operating conditions and fault information can be used for troubleshooting and maintenance.

This can reduce the need to troubleshoot the motor-control system entirely through physical inspection.

---

10. EtherNet/IP Communication

One of the important features of the 20G1ALE395AN0NNNNN is its embedded EtherNet/IP communication capability.

This allows the drive to communicate with an industrial automation network without necessarily requiring a separate external communication module for basic EtherNet/IP integration.

Typical information exchanged over the network can include:

Network Data	Typical Function
Start Command	Starts motor operation
Stop Command	Stops motor operation
Speed Reference	Sets desired motor speed
Frequency Reference	Provides operating frequency command
Output Frequency	Reports actual drive output frequency
Output Current	Reports motor current
Drive Status	Provides operating-state information
Fault Status	Reports drive faults
Alarm Information	Provides warning information
Control Word	Coordinates drive commands
Status Word	Returns drive operating status
Diagnostic Data	Supports troubleshooting

25. Five Popular Allen-Bradley Reference Models

For a broader Allen-Bradley comparison, the following PowerFlex models are useful reference products within the same general variable-frequency-drive family.

Model	Product Series	Voltage Class	Approximate Capacity	Typical Application
20G1ALE355AN0NNNNN	PowerFlex 755	600 VAC	High-power, Frame 8	Pumps, fans, conveyors
20G1ALE395AN0NNNNN	PowerFlex 755	600 VAC	High-power, Frame 8	Large industrial motors

These models are particularly useful when the main requirement is to remain within the same high-power PowerFlex 755 platform while adjusting the available current capacity.

---

26. Why the 395 A Model Is Important

The 20G1ALE395AN0NNNNN occupies a substantial power range within the Frame 8 PowerFlex 755 family.

Its 395 A Light Duty rating gives it enough capacity for large motors, while the Normal Duty and Heavy Duty ratings provide different operating points for applications with different load characteristics.

This makes the model appropriate for installations where motor load is significant and where a compact low-power VFD would not provide sufficient current capacity.

For industrial engineering projects, the 395 A class is particularly relevant to large process pumps, large fans, conveyors, compressors, and other machinery that requires substantial motor power.

---

27. Light Duty vs Normal Duty vs Heavy Duty

Duty classification is important when selecting a large industrial drive.

Light Duty

Light Duty applications generally have relatively moderate overload requirements and smoother load characteristics.

Typical examples may include certain centrifugal pumps and fans.

For this model, the Light Duty rating is approximately:

395 A continuous / 435 A for 1 minute / 450 HP

Normal Duty

Normal Duty applications require more capability than typical variable-torque loads but may not require the highest heavy-duty overload performance.

For this model:

355 A continuous / 391 A for 1 minute / up to 533 A for 3 seconds / approximately 400 HP

Heavy Duty

Heavy Duty operation is intended for applications where the motor experiences higher torque requirements or more demanding acceleration and overload conditions.

For this model:

295 A continuous / 443 A for 1 minute / up to 533 A for 3 seconds / approximately 350 HP

The correct duty rating should be selected from the actual load characteristics rather than simply choosing the highest horsepower number.

---

28. Typical Industrial Equipment

The 20G1ALE395AN0NNNNN can be considered for equipment such as:

Equipment	Suitability
Large Centrifugal Pumps	Suitable
Water Pumps	Suitable
Wastewater Pumps	Suitable
Cooling Pumps	Suitable
Industrial Fans	Suitable
Large Blowers	Suitable
Conveyors	Suitable
Material Handling Systems	Suitable
Compressors	Suitable
Process Machinery	Suitable
Industrial Ventilation	Suitable
Production Equipment	Suitable
Bulk Material Systems	Suitable
Large Mechanical Drives	Suitable

Actual suitability depends on the motor nameplate current, load torque curve, acceleration requirements, braking requirements, environmental conditions, and control method.

---

29. Advantages for Automation Systems

The embedded EtherNet/IP interface is especially useful in automated production environments.

A typical system can include:

PLC → Industrial Network → PowerFlex 755 → Motor → Mechanical Equipment

The control system can issue commands to the drive while receiving operational feedback.

This arrangement can reduce the amount of hardwired control wiring required for basic command and status functions.

The drive can also become part of the plant’s diagnostic architecture, allowing operators to view motor-control information from an HMI or supervisory system.

---

30. Advantages for Maintenance

Large industrial motors and drives are expensive pieces of equipment, so maintenance visibility is important.

Networked drive information can help maintenance personnel identify:

• Drive running status
• Motor current
• Output frequency
• Fault conditions
• Warning conditions
• Command status
• Speed reference
• Operating state
• Diagnostic information

This can help reduce unnecessary physical troubleshooting and provide a clearer picture of the drive’s operating condition.

---

31. Replacement and Retrofit Considerations

When replacing an existing PowerFlex 755 drive, the complete catalog number should be checked.

The following items should be compared:

Check Item	Required
Voltage	Yes
Phase	Yes
Current	Yes
Duty Rating	Yes
Motor HP	Yes
Frame Size	Yes
Enclosure	Yes
Cooling	Yes
Network	Yes
Dynamic Braking	Yes
Input Filtering	Yes
CM Jumper Configuration	Yes
HIM Configuration	Yes
Cabinet Dimensions	Yes
Motor Cable	Yes
Control Wiring	Yes
Parameter Settings	Yes

A drive with a similar horsepower rating is not automatically a direct replacement.

---

32. Motor Selection

For the 20G1ALE395AN0NNNNN, motor selection should consider:

• Motor rated voltage
• Full-load current
• Rated frequency
• Motor horsepower
• Motor speed
• Motor service factor
• Starting torque
• Running torque
• Load inertia
• Acceleration time
• Deceleration time
• Operating speed range
• Motor insulation
• Cable length

For large motors, the current rating is particularly important.

A motor’s horsepower rating by itself does not provide enough information to confirm drive compatibility.
