3. Product Series

The 20G11NE2P7AA0NNNNN belongs to the PowerFlex 755 series.

The PowerFlex 755 series is intended for industrial variable-speed motor applications where the drive needs to provide more than basic motor starting and stopping.

The series is suitable for machinery that requires controlled motor speed, adjustable acceleration and deceleration, braking functions, process control, diagnostics, and integration into an industrial automation system.

A major advantage of using a series-based drive platform is consistency. Different drive sizes within the same family can be used for different motor capacities while maintaining a similar overall control philosophy.

6. Electrical Characteristics

The drive has a nominal 600 VAC three-phase input rating.

Its nominal output current is 2.7 A.

For motor selection, the motor’s nameplate current should be considered carefully. Horsepower alone should not be used as the only selection criterion.

A motor with a nominal rating close to 2 HP may still require a different drive if its actual full-load current, overload characteristics, acceleration requirements, or operating duty exceed the capabilities of this model.

7. Normal-Duty Rating

The normal-duty rating of this model is approximately 2 HP / 1.5 kW.

Normal-duty operation is generally associated with applications where the motor does not experience severe continuous overload conditions.

Typical examples include:

• Fans
• Pumps
• Light conveyors
• Small blowers
• Material feeders
• Small machine mechanisms
• Auxiliary production equipment

8. Heavy-Duty Rating

The heavy-duty rating is approximately 1 HP / 0.7 kW.

Heavy-duty applications generally place greater demands on the drive because the motor may experience higher starting torque, more frequent acceleration, repeated overload conditions, or significant mechanical loading.

When the machine requires heavy starting torque or frequent acceleration and deceleration, the heavy-duty rating should be considered instead of simply using the normal-duty horsepower value.

9. Dimensions

The approximate physical dimensions of the drive are:

Mechanical Parameter	Specification
Model	20G11NE2P7AA0NNNNN
Height	454 mm
Width	190 mm
Depth	212 mm
Overall Size	Approximately 454 × 190 × 212 mm
Frame	Frame 3
Cooling	Air Cooled
Weight	12 kg
Weight (kg)	12 kg

These dimensions should be regarded as equipment-envelope dimensions for planning purposes.

A cabinet designer should provide additional space for power cables, control wiring, ventilation, heat dissipation, terminal access, maintenance, and safe servicing.

10. Weight

The approximate product weight is 12 kg.

Model	20G11NE2P7AA0NNNNN
Product Weight	Approximately 12 kg
Weight (kg)	12 kg

The weight of the complete packaged product may be higher because of packaging materials and accessories.

11. Cooling System

The drive uses an air-cooled design.

During operation, the internal switching components generate heat. The cooling system transfers this heat away from the drive.

For reliable operation, the electrical cabinet should provide adequate airflow.

The installation should avoid:

• Blocked ventilation paths
• Excessive cabinet temperature
• Heavy dust accumulation
• Direct exposure to liquids
• Excessive humidity
• Poorly arranged heat-producing equipment

Good cabinet design is particularly important when several drives or other heat-producing electrical components are installed in the same enclosure.

12. Enclosure

The model uses an open-type construction with an IP20-class protection arrangement.

It is therefore normally intended to be installed inside an appropriate electrical enclosure when the surrounding environment requires protection from dust, water, mechanical impact, or other contaminants.

The external cabinet should be selected according to the actual installation environment.

For industrial environments, cabinet design may also need to consider:

• Dust
• Oil mist
• Moisture
• Temperature
• Vibration
• Corrosive substances
• Electrical interference
• Maintenance requirements

13. Dynamic Braking

One of the useful characteristics of this model is the internal dynamic-braking transistor.

Dynamic braking can help control motor deceleration when the mechanical load has substantial stored energy.

This feature is particularly useful for equipment that needs controlled stopping.

Potential applications include:

• High-inertia conveyors
• Rotating equipment
• Material-handling systems
• Rapid stopping mechanisms
• Certain hoisting-related auxiliary systems
• Machines with frequent acceleration and deceleration

The actual braking system must still be designed according to the required stopping time, regenerated energy, braking resistor requirements, and application duty.

14. EMC Filtering

The model includes an EMC filter configuration.

Variable-frequency drives use high-frequency switching to control motor voltage and frequency. This switching can produce electromagnetic disturbances.

A suitable EMC arrangement can help reduce interference when the drive is correctly installed.

Proper EMC performance also depends on:

• Grounding
• Shielding
• Motor-cable selection
• Cable routing
• Cabinet design
• Cable length
• Correct termination
• Separation between power and sensitive signal wiring

15. HIM Configuration

The model is supplied without a standard HIM keypad.

This configuration can be useful when the drive is intended to be operated as part of a larger automation system.

In such an installation, the drive may receive commands and speed references from a controller or communication network.

A local interface can still be useful during:

• Commissioning
• Parameter setup
• Maintenance
• Fault diagnosis
• Manual testing
• Troubleshooting

Therefore, the absence of a standard HIM should be considered when planning commissioning and maintenance procedures.

16. Product Applications

The 20G11NE2P7AA0NNNNN is suitable for many smaller industrial motor-control applications.

Typical applications include:

Application	Typical Function
Conveyor	Variable-speed transport
Pump	Flow adjustment
Fan	Airflow control
Blower	Variable airflow
Feeder	Controlled material feed
Packaging Machine	Controlled motor movement
Material Handling	Speed and acceleration control
Small Mixer	Adjustable motor speed
Process Equipment	Variable-speed operation
Production Machinery	Controlled motor operation
Machine Auxiliary System	Variable-speed auxiliary drive
Ventilation Equipment	Adjustable airflow

17. Conveyor Applications

Small industrial conveyors frequently require different operating speeds.

A fixed-speed motor may be sufficient for a simple conveyor, but variable-speed control becomes useful when the production line needs adjustable material flow.

The drive can provide:

• Smooth starting
• Adjustable running speed
• Controlled stopping
• Reduced mechanical shock
• Production-line speed matching
• Improved process flexibility

For conveyors with high inertia or frequent starts and stops, the actual load and braking requirements should be evaluated carefully.

18. Pump Applications

Variable-speed control is useful when pump demand changes during operation.

The drive can adjust motor speed according to process requirements.

Typical applications include:

• Water circulation
• Cooling systems
• Transfer systems
• Auxiliary process pumps
• Small industrial pumping systems

Instead of operating the motor continuously at maximum speed, the drive can provide a controlled speed appropriate to the process.

19. Fan and Blower Applications

Fans and blowers are natural variable-speed applications.

Airflow requirements can change depending on:

• Production conditions
• Temperature
• Machine load
• Ventilation demand
• Process requirements

The drive can therefore be used to regulate motor speed rather than simply switching the motor fully on or fully off.

20. Feeder Applications

Material feeders often require controlled and repeatable speed.

The drive can be used with equipment such as:

• Screw feeders
• Belt feeders
• Roll feeders
• Material-transfer mechanisms
• Small production feeders

The correct drive size depends on the motor current and the torque required by the feeder.

21. Packaging Machinery

Packaging machinery often uses several motors for different movements.

A variable-frequency drive can control smaller motor-driven sections such as:

• Rollers
• Conveyors
• Feed mechanisms
• Material transport
• Auxiliary rotating equipment

Controlled acceleration can help reduce mechanical shock and improve the smoothness of machine operation.

22. Main Product Advantages

22.1 Adjustable Motor Speed

The most important advantage is adjustable motor speed.

The drive can change motor operating frequency and voltage to achieve controlled variable-speed operation.

22.2 Smooth Acceleration

Acceleration can be controlled rather than applying full-speed operation immediately.

This can reduce mechanical shock and improve machine behavior.

22.3 Controlled Deceleration

The drive can provide controlled motor deceleration.

This is useful for machinery that needs predictable stopping performance.

22.4 Dynamic Braking Capability

The integrated braking transistor provides additional flexibility for applications where controlled deceleration is important.

22.5 Industrial Automation Integration

The PowerFlex 755 architecture is suitable for integration into industrial automation systems.

This allows the drive to function as part of a complete machine-control system rather than operating as an isolated motor controller.

22.6 600 VAC Capability

The 600 VAC class makes this model suitable for applications requiring a higher-voltage industrial motor supply.

This is an important distinction from many smaller drives designed primarily for 200–240 VAC or 380–480 VAC systems.

22.7 Compact Frame 3 Design

The Frame 3 configuration provides a standardized mechanical arrangement suitable for cabinet-based industrial installation.

22.8 EMC Filtering

The EMC filtering configuration can help support electrically cleaner installations when the complete installation is correctly designed.

22.9 Flexible Application Range

Although the drive is relatively small in power capacity, it can be used across a broad range of industrial applications, including conveyors, pumps, fans, feeders, and auxiliary machinery.

29. Why the 20G11NE2P7AA0NNNNN Is Useful

The biggest advantage of this particular model is the combination of a relatively small motor rating with the functionality of a higher-performance industrial drive platform.

For a machine builder, this can make the drive useful for compact machinery that still needs:

• Variable-speed operation
• Controlled acceleration
• Controlled deceleration
• Dynamic braking
• Industrial communications
• Process control
• Diagnostic functions
• Cabinet-based installation
• Consistent drive-family architecture

30. Recommended Application Matching

Application	Suitability	Main Reason
Small Conveyor	Excellent	Adjustable speed and controlled starting
Small Pump	Excellent	Variable-speed flow control
Small Fan	Excellent	Adjustable airflow
Small Blower	Excellent	Variable-speed operation
Feeder	Very Good	Controlled feed rate
Packaging Equipment	Very Good	Controlled motor movement
Material Handling	Very Good	Speed and acceleration control
Small Mixer	Good	Adjustable motor speed
Small Process Machine	Very Good	Flexible speed control
High-Inertia Equipment	Requires Evaluation	Braking and overload must be checked
Large Motor	Not Suitable Without Correct Sizing	Current rating may be insufficient
Heavy Continuous Overload	Requires Evaluation	Heavy-duty rating must be observed

31. Important Selection Considerations

Before replacing another drive with 20G11NE2P7AA0NNNNN, the following points should be checked.

Motor Voltage

The motor voltage must be compatible with the drive’s output requirements.

Motor Current

The motor’s full-load current is one of the most important selection values.

Duty Rating

Determine whether the application should be evaluated under normal-duty or heavy-duty conditions.

Acceleration

If the machine needs rapid acceleration, the required motor current may be significantly higher than the steady-state current.

Deceleration

If the machine needs rapid stopping, the braking requirements should be evaluated.

Mechanical Load

High-inertia loads, conveyors, mixers, and other torque-intensive machines can require different drive sizing than simple fan or pump applications.

Ambient Temperature

The cabinet temperature must remain within the drive’s allowable operating range.

Installation Space

The approximate drive envelope is:

454 mm × 190 mm × 212 mm

The cabinet should provide additional clearance around the drive.

32. Advantages for Machine Builders

For machine builders, the model can provide a standardized approach to variable-speed motor control.

A machine builder can design a control cabinet around the drive and use the same general PowerFlex control concept across several machine configurations.

This can simplify:

• Electrical design
• Operator training
• Maintenance procedures
• Spare-parts planning
• Troubleshooting
• Drive parameter management
• Machine commissioning

33. Advantages for Maintenance Departments

For maintenance personnel, the drive provides a structured approach to motor-drive troubleshooting.

Common diagnostic areas include:

• Overcurrent
• Overvoltage
• Undervoltage
• Overtemperature
• Motor overload
• Communication problems
• Parameter problems
• Acceleration problems
• Deceleration problems
• Braking problems

A well-maintained drive system can also make troubleshooting considerably easier because the drive provides information about the motor-control process.

34. Advantages for Process Control

Variable-speed operation allows the machine to respond more closely to actual production requirements.

For example, a conveyor can slow down when material flow decreases.

A fan can reduce speed when airflow demand is lower.

A pump can adjust speed according to process requirements.

A feeder can change material delivery rate.

This flexibility is one of the major reasons industrial variable-frequency drives are widely used in automated machinery.

36. Final Product Assessment

The 20G11NE2P7AA0NNNNN is a compact 600 VAC PowerFlex 755 variable-frequency drive intended for industrial three-phase motor control.

Its 2.7 A output rating, 2 HP normal-duty capacity, 1 HP heavy-duty capacity, Frame 3 construction, air cooling, EMC filtering, and dynamic-braking transistor make it suitable for a wide range of smaller industrial motor applications.

The model is particularly appropriate when the application requires more control flexibility than a basic motor starter can provide.

It can be used for adjustable-speed conveyors, pumps, fans, blowers, feeders, packaging equipment, material-handling systems, and other machinery where controlled motor operation is required.

The approximate physical dimensions are 454 mm × 190 mm × 212 mm, and the product weight is approximately 12 kg.

For replacement purposes, the complete catalog number should always be checked. A model with a similar horsepower rating is not necessarily electrically interchangeable because voltage class, output current, duty rating, enclosure, braking, filtering, control options, and mechanical dimensions can differ.

Among the closely related models, the 20G11NE1P7AA0NNNNN, 20G11NE3P9AA0NNNNN, 20G11NE6P1AA0NNNNN, and 20G11NE9P0AA0NNNNN can be considered when a lower or higher motor capacity is required within the same general 600 VAC PowerFlex 755 range.

For a direct replacement, however, the complete model configuration—not merely the PowerFlex series or horsepower—should be matched carefully.
