Allen-Bradley 20G11NE032AA0NNNNN Product Details and Technical Specification

1. Product Overview

20G11NE032AA0NNNNN is a PowerFlex 755 series AC variable frequency drive (VFD) designed for industrial three-phase motor control.

It belongs to the 600 VAC class and has an output current rating of approximately 32 A. In the normal-duty range, it is generally associated with a motor capacity of approximately 30 HP, while the heavy-duty rating is lower and is intended for applications with greater overload or torque requirements.

The drive is designed for applications where motor speed, acceleration, deceleration, torque, and operating status need to be controlled accurately.

Compared with a simple fixed-speed motor starter, this type of drive provides much greater flexibility. Motor speed can be adjusted according to the process requirement, and the motor can be accelerated and decelerated in a controlled manner.

The model is particularly suitable for industrial machinery, conveyors, pumps, fans, blowers, material-handling equipment, production lines, feeders, process equipment, and other applications requiring adjustable-speed motor control.

---

2. Brand and Product Series

The 20G11NE032AA0NNNNN belongs to the PowerFlex 755 family and is positioned above the 22 A class in the same 600 VAC product range.

For applications where a 22 A drive is close to its operating limit, a 32 A model provides additional current capacity and can offer more selection flexibility.

---

3. Complete Model Identification

The complete catalog number is:

20G11NE032AA0NNNNN

The model number contains multiple configuration characters that define the electrical and functional arrangement of the drive.

For practical purchasing and replacement work, the complete catalog number should be retained rather than selecting a replacement based only on the first several characters.

Different suffix configurations can change functions such as:

• Input arrangement
• Enclosure configuration
• Operator interface
• Communication arrangement
• EMC configuration
• Braking capability
• Control options

Therefore, the complete catalog number is important when replacing an existing drive.

---

4. Main Technical Parameters

The 32 A current rating is the most important electrical characteristic when matching this drive to a motor.

For final engineering selection, motor nameplate current should be checked rather than selecting solely by horsepower.

---

5. 600 VAC Voltage Class

The 20G11NE032AA0NNNNN is intended for a 600 VAC-class industrial power system.

This makes it appropriate for industrial electrical systems where the available line voltage is compatible with the drive’s rated input range.

The voltage class is an important selection parameter.

A 480 VAC drive and a 600 VAC drive should not be treated as interchangeable simply because they have the same current rating.

When selecting this type of equipment, the following should be checked together:

---

6. 32 A Output Current

The drive has an approximately 32 A output current rating.

This places it in the medium-power range of the PowerFlex 755 600 VAC family.

The 32 A capacity makes the model useful for applications where a smaller drive may not provide enough current margin.

For example, if an application is close to the current limit of a 22 A model, moving to a 32 A model can provide a more appropriate selection, provided that the motor and duty requirements are compatible.

The actual motor full-load current should always be compared with the drive’s applicable current rating.

---

7. 30 HP Normal-Duty Rating

The model is generally associated with approximately 30 HP normal-duty operation.

Normal-duty applications typically have relatively predictable loading conditions and do not continuously demand severe overload performance.

Typical examples include:

• Centrifugal pumps
• Fans
• Blowers
• Conveyors
• Standard material-handling equipment
• General production machinery
• Process equipment
• Feeders

The actual application must still be evaluated based on current, torque, acceleration, inertia, and duty cycle.

---

8. Heavy-Duty Capability

For applications involving greater torque demand, repeated acceleration, or heavier loading, the heavy-duty rating becomes important.

The approximate heavy-duty capacity is around 25 HP, subject to the applicable drive rating and operating conditions.

Heavy-duty applications may include:

• High-inertia conveyors
• Heavily loaded feeders
• Mixers
• Material-handling machinery
• Machinery with frequent starts and stops
• Machinery requiring higher acceleration torque
• Equipment with demanding deceleration requirements

The motor should be selected based on actual load characteristics rather than simply matching horsepower.

---

9. Power Conversion

The approximate power equivalents are:

The horsepower-to-kilowatt conversion is a mathematical equivalence.

The actual drive selection should be based primarily on electrical current and application duty.

---

10. Frame 4 Construction

The 32 A model is associated with a Frame 4 mechanical configuration.

Frame size affects:

• Drive dimensions
• Mounting arrangement
• Cabinet layout
• Cooling requirements
• Cable access
• Service clearance
• Weight
• Replacement compatibility

A Frame 4 drive should therefore not automatically be considered a drop-in replacement for a smaller Frame 3 drive.

Even when two drives have similar electrical functions, differences in physical frame size can require modifications to the electrical cabinet.

---

11. Dimensions and Weight

For planning purposes, the drive should be treated as a medium-size cabinet-mounted power electronic unit.

The approximate product weight is in the range of:

18–20 kg

The mechanical envelope is approximately in the 600 × 300 × 300 mm class, depending on the exact hardware configuration and installation arrangement.

Important: The above dimensions are suitable for preliminary space planning only. Exact mounting-hole locations and cabinet cutout dimensions should be taken from the applicable mechanical drawing for the specific hardware version before fabrication.

---

12. Forced-Air Cooling

The drive uses forced-air cooling to remove heat produced by its power electronics.

The cooling system is important because the power semiconductor section can generate significant heat during normal operation.

Cabinet design should therefore consider:

• Ambient temperature
• Internal cabinet temperature
• Airflow
• Ventilation
• Fan operation
• Clearance around the drive
• Heat generated by other equipment
• Cabinet orientation

Poor ventilation can increase the internal operating temperature and potentially reduce equipment reliability.

---

13. Open-Type Installation

The drive is intended for installation within an appropriate electrical enclosure rather than being used as a completely exposed field device.

The enclosure provides protection from:

• Dust
• Moisture
• Mechanical impact
• Oil contamination
• Conductive particles
• Accidental contact

The enclosure also provides a controlled environment for cooling and cable routing.

---

14. Variable Frequency Operation

The primary function of the drive is variable-frequency motor control.

A conventional fixed-speed motor connected directly to the power supply normally operates at a speed determined mainly by the motor design and supply frequency.

A VFD changes the electrical frequency supplied to the motor.

As a result, motor speed can be adjusted.

For example:

Low Frequency → Low Motor Speed

Medium Frequency → Medium Motor Speed

High Frequency → Higher Motor Speed

The actual motor speed is also influenced by motor characteristics and load conditions.

---

15. Controlled Acceleration

One of the major benefits of the drive is controlled acceleration.

Instead of applying a sudden full-speed command, the drive can gradually increase motor speed.

This can reduce mechanical shock on:

• Belts
• Chains
• Gearboxes
• Couplings
• Shafts
• Bearings
• Rollers
• Conveyor structures
• Machine frames

This feature is especially valuable in machinery with high mechanical inertia.

---

16. Controlled Deceleration

The drive can also provide controlled deceleration.

This is useful when a machine needs to slow down smoothly instead of stopping abruptly.

Typical applications include:

• Conveyors
• Rollers
• Material-handling machines
• Process equipment
• Production lines
• High-inertia machinery

Where the application produces significant regenerative energy during deceleration, an appropriate braking arrangement may be required.

---

17. Dynamic Braking

Dynamic braking is particularly useful for machinery that needs controlled stopping.

When a motor decelerates, energy can be returned to the drive’s DC bus.

If this energy becomes excessive, the DC-bus voltage can rise.

A braking system can dissipate the excess energy through an appropriately selected braking resistor.

This can be useful in:

• High-inertia conveyors
• Roll systems
• Material handling
• Rapid stopping applications
• Machinery with frequent deceleration

The braking resistor must be properly selected for the actual machine.

---

18. Industrial Communication

The PowerFlex 755 platform is designed for integration with industrial automation systems.

Depending on the exact configuration, the drive can exchange operating and diagnostic information with the control system.

Typical information may include:

• Start command
• Stop command
• Speed reference
• Direction command
• Output frequency
• Motor current
• Drive status
• Fault status
• Alarm information
• Operating condition

This makes the drive suitable for centralized machine control.

---

19. Product Applications

The 20G11NE032AA0NNNNN can be applied to a broad range of industrial equipment.

---

20. Conveyor Applications

Conveyors are one of the most common applications for industrial VFDs.

A conveyor may need different operating speeds during:

• Startup
• Normal production
• Product changeover
• Inspection
• Maintenance
• Shutdown

Using a variable-speed drive allows the machine designer to select the operating speed according to production requirements.

The drive can also provide controlled acceleration, reducing sudden mechanical loading on the conveyor.

---

21. Pump Applications

The drive can be used to control pump motor speed.

This can be useful for:

• Water circulation
• Process fluids
• Cooling systems
• Industrial pumping
• Fluid transfer
• Process supply

Instead of running a pump continuously at full speed, the motor can be operated at a speed appropriate to the process.

For centrifugal pump applications, variable-speed operation can be especially useful when process demand changes.

---

22. Fan and Blower Applications

Fans and blowers often operate under changing process conditions.

The drive can adjust motor speed according to required airflow.

Typical applications include:

• Factory ventilation
• Exhaust systems
• Cooling systems
• Process ventilation
• Air-handling equipment
• Industrial machine cooling

This can provide much greater operating flexibility than fixed-speed operation.

---

23. Material-Handling Applications

Material-handling systems often require smooth motor operation.

The drive can be used on:

• Conveyors
• Rollers
• Feed systems
• Transfer mechanisms
• Material feeders
• Automated handling equipment

Controlled acceleration and deceleration can help protect both the mechanical equipment and the transported product.

---

24. Packaging Applications

Packaging machinery frequently uses multiple motors operating at coordinated speeds.

A VFD can be used for:

• Feed conveyors
• Rollers
• Product transportation
• Auxiliary mechanisms
• Material feeding
• Machine sections

The drive can become part of the larger machine-control architecture.

---

25. Process Machinery

Industrial process machinery often requires different operating speeds at different stages.

For example:

The flexibility of variable-speed operation makes the drive suitable for many types of process machinery.

---

A typical system can be arranged as:

Industrial Controller

↓

Industrial Network

↓

20G11NE032AA0NNNNN

Mechanical Load

This structure allows motor operation to become part of the overall machine sequence.

---

28. Advantages for System Integrators

System integrators can benefit from using several drives from the same family.

For example, a production line may use:

• One drive for a conveyor
• One drive for a feeder
• One drive for a pump
• One drive for a fan
• One drive for an auxiliary machine

Using drives from a common family can make system configuration and maintenance more consistent.

---

29. Advantages for Maintenance

A standardized drive platform can simplify maintenance activities.

Maintenance personnel can become familiar with:

• Drive parameters
• Fault handling
• Operating status
• Communication structure
• Motor-control settings
• Troubleshooting procedures
• Replacement procedures

This can reduce the learning curve when multiple machines use related drive models.

---

30. Advantages for Mechanical Equipment

Controlled motor operation can help reduce sudden mechanical loading.

Potentially affected components include:

• Bearings
• Gearboxes
• Couplings
• Belts
• Chains
• Shafts
• Rollers
• Conveyor structures
• Machine frames

The actual improvement depends on the machine’s mechanical design and drive settings.

---

31. Motor Selection Requirements

The drive should be matched to the actual motor.

The motor nameplate current is especially important.

A motor should not be selected simply because its horsepower appears to match the drive.

---

32. Five Same-Series or Closely Related Models

The following models are useful for comparison around the 32 A 600 VAC PowerFlex 755 range.

These are primarily capacity-based comparison models.

The final suffix should always be checked before treating any catalog number as an exact replacement because configuration characters can affect the equipment arrangement.

---

33. Same-Series Comparison

---

34. Five Popular Related Models Under the Same Brand

For a broader comparison, the following models represent commonly encountered products within the same general drive portfolio.

These are useful comparison choices when evaluating different drive capacities or product families.

They should not be considered direct electrical replacements without checking voltage, current, motor rating, control method, communication requirements, physical dimensions, and configuration.

---

35. Broader Product Comparison

---

36. 20G11NE032AA0NNNNN vs. 20G11NE022AA0NNNNN

These two models are especially useful to compare because they are close in the same product family.

The 32 A model is therefore appropriate when the 22 A class is not sufficient for the motor or load.

However, selecting the larger model only to obtain additional capacity can increase cabinet size, weight, cost, and thermal requirements.

The best selection is the smallest suitable model that meets the actual electrical and mechanical requirements.

---

37. 20G11NE032AA0NNNNN vs. 20G11NE041AA0NNNNN

51. Conclusion

The 20G11NE032AA0NNNNN is a suitable choice when an industrial application requires a 600 VAC-class, three-phase variable frequency drive with approximately 32 A output capability.

Its approximately 30 HP normal-duty capacity makes it suitable for a wide range of medium-sized industrial machines, while its approximately 25 HP heavy-duty capability provides additional flexibility for more demanding applications.

The drive is particularly well suited to conveyors, pumps, fans, blowers, feeders, material-handling equipment, packaging machinery, and process equipment.

The biggest practical advantages are its higher current capacity compared with smaller models, adjustable motor speed, controlled acceleration and deceleration, industrial automation compatibility, and suitability for cabinet-mounted industrial applications.

For physical planning, the product should be treated as a Frame 4-class drive weighing approximately 18–20 kg, with a preliminary mechanical envelope in the 600 × 300 × 300 mm class. These values are intended for planning purposes; exact mounting dimensions should be confirmed before cabinet fabrication.

For model selection, the closest capacity alternatives are 20G11NE017AA0NNNNN, 20G11NE022AA0NNNNN, 20G11NE027AA0NNNNN, 20G11NE032AA0NNNNN, and 20G11NE041AA0NNNNN.

Among these, 20G11NE032AA0NNNNN is particularly suitable when a 22 A model is too small but a 41 A model would provide unnecessary additional capacity.

The final selection should always be based on the actual motor nameplate current, voltage, duty class, overload requirement, load torque, acceleration/deceleration requirements, braking requirements, ambient temperature, cabinet cooling, and available installation space.
