20G11NE011JA0NNNNN — PowerFlex 755 AC Drive

1. Product Overview

The 20G11NE011JA0NNNNN is an industrial AC variable frequency drive from the PowerFlex 755 series.

It is designed for three-phase industrial motor applications where accurate speed regulation, controlled acceleration and deceleration, motor protection, network communication, diagnostics, and flexible automation integration are required.

This model is an 11 A, 600 VAC class, three-phase AC drive. It is configured as an air-cooled, open-type drive with embedded Ethernet/IP communication capability, AC input with DC terminals, a built-in dynamic-braking transistor, EMC filtering, and no local HIM display installed as part of this particular catalog configuration.

The drive is intended for industrial control cabinets and machinery where an AC motor needs to operate at adjustable speed rather than simply running continuously at the fixed speed determined by the incoming AC frequency.

The 11 A rating places this model in a useful medium-small industrial motor-control range. Depending on the application duty, it can support motors up to approximately 10 HP under normal-duty conditions or approximately 7.5 HP under heavy-duty conditions.

6. Rated Current

The rated continuous output current of this model is approximately 11 A.

For variable frequency drives, output current is one of the most important selection parameters.

Horsepower is useful for general classification, but the actual motor nameplate current should be checked before selecting the drive.

For example, two motors with the same nominal horsepower may have different current requirements because of differences in:

• Motor efficiency
• Motor power factor
• Motor design
• Motor voltage
• Motor speed
• Duty cycle
• Load characteristics
• Ambient conditions
• Starting requirements

For this reason, the 11 A rating should be considered together with the motor nameplate and actual machine load.

---

7. Normal-Duty and Heavy-Duty Ratings

One of the important characteristics of this model is the difference between normal-duty and heavy-duty operation.

Duty Rating	Approximate Capacity
Normal Duty	10 HP
Heavy Duty	7.5 HP
Output Current	11 A
Application Consideration	Depends on actual motor current and overload requirement

Normal-duty applications generally have less severe overload requirements.

Heavy-duty applications can involve higher starting torque, higher continuous load, or more demanding acceleration and overload conditions.

Therefore, a motor that is nominally within the 10 HP range may not automatically be appropriate if the machine requires heavy-duty torque.

---

8. 600 VAC Class

The 20G11NE011JA0NNNNN is a 600 VAC class drive.

This differentiates it from PowerFlex 755 models designed around lower voltage classes such as 480 VAC.

A 600 VAC class drive is useful in industrial electrical systems where the available three-phase supply is designed around this voltage range.

Typical environments can include:

• Manufacturing facilities
• Industrial processing plants
• Material-handling systems
• Heavy machinery
• Pumping systems
• Large production equipment
• Industrial utility systems

Correct incoming voltage must always be confirmed before installation.

---

9. Three-Phase Motor Control

The drive is designed for three-phase AC motor applications.

The drive receives electrical power from the industrial AC supply and produces a controlled three-phase output for the motor.

By controlling the output frequency and voltage relationship, the drive can regulate motor speed and torque.

This provides much greater flexibility than directly connecting a motor to a fixed-frequency power supply.

---

10. Variable-Speed Operation

The main purpose of the drive is to provide controlled variable-speed operation.

A machine can therefore operate at different speeds according to production requirements.

For example:

Operating Condition	Possible Drive Function
Machine startup	Low-speed controlled acceleration
Normal production	Programmed operating speed
Reduced production	Lower speed
Product changeover	Reduced speed
Positioning	Controlled low speed
Machine stopping	Controlled deceleration
Emergency process response	Application-dependent stopping strategy

This flexibility can simplify machine design and improve process control.

---

11. Acceleration Control

The drive can control how quickly the motor accelerates.

Instead of applying the motor to full operating speed immediately, the drive can use a controlled acceleration ramp.

This can reduce mechanical shock on:

• Gearboxes
• Couplings
• Belts
• Chains
• Shafts
• Rollers
• Bearings
• Conveyors
• Machine structures

Controlled acceleration is particularly useful when the machine contains a large rotating mass or when the product being transported must not be subjected to sudden movement.

---

12. Deceleration Control

The drive can also control motor deceleration.

A controlled deceleration profile can reduce sudden mechanical loading.

This is useful for:

• Conveyors
• Material-handling systems
• Production machinery
• Fans
• Blowers
• Pumps
• Processing equipment

Where rapid stopping is required, the dynamic-braking configuration can become an important part of the system design.

---

13. Dynamic Braking

The 20G11NE011JA0NNNNN includes a dynamic-braking transistor as part of its configuration.

Dynamic braking is useful when a motor has substantial rotating inertia or when the machine needs controlled deceleration.

During deceleration, energy from the rotating motor and mechanical load can be transferred into the drive’s DC bus.

A suitable braking resistor arrangement can then dissipate this energy.

Typical applications include:

• High-inertia conveyors
• Material-handling machinery
• Feed systems
• Packaging machinery
• Rapid-cycle machines
• Machinery requiring faster stopping

The braking resistor must be selected according to the actual application and required braking duty.

---

14. Embedded Ethernet/IP

The model includes embedded Ethernet/IP communication capability.

This allows the drive to participate directly in a networked industrial control system.

Typical information exchanged can include:

Information	Function
Start Command	Starts the motor
Stop Command	Stops the motor
Speed Reference	Sets motor speed
Direction	Controls rotation
Enable	Permits operation
Reset	Clears suitable faults
Drive Status	Monitors operating condition
Output Frequency	Monitors motor speed command
Output Current	Monitors motor loading
Fault Code	Identifies drive faults
Alarm	Indicates abnormal conditions
Operating State	Provides drive condition

This two-way communication is particularly useful in automated production systems.

---

15. No Local HIM

This particular catalog configuration is specified with a blank / no HIM arrangement.

HIM means Human Interface Module.

A drive without a local HIM can still be integrated into a machine control system.

In a networked installation, the drive may be configured and monitored through the control system or suitable engineering tools.

This configuration can be attractive when the machine already has a central operator interface and a local drive display is not required.

It can also help keep the drive configuration focused on cabinet-level automation rather than local operator interaction.

---

16. Open-Type Construction

The drive uses an open-type configuration.

This means the drive is intended to be installed inside an appropriate electrical enclosure or control cabinet rather than being treated as a fully sealed standalone field device.

The cabinet should protect the drive from:

• Water
• Oil
• Excessive dust
• Conductive particles
• Metal debris
• Corrosive substances
• Condensation

The cabinet should also provide adequate cooling.

---

17. Forced-Air Cooling

The drive uses forced-air cooling.

Power electronics generate heat during operation.

The cooling system transfers heat away from the power components and allows the drive to operate within its intended thermal range.

Cabinet design should therefore account for:

• Drive heat generation
• Ambient temperature
• Cabinet size
• Air circulation
• Other heat-producing components
• Filter condition
• Fan condition

Several drives installed in the same cabinet may require additional thermal analysis.

---

18. EMC Filtering

This particular configuration includes filtering intended to support electromagnetic compatibility requirements.

VFDs generate high-frequency switching waveforms, and improper installation can result in electrical noise.

A properly designed installation should consider:

• Motor cable shielding
• Cable routing
• Grounding
• Cabinet bonding
• Separation of control and power wiring
• Motor-frame bonding
• Communication cable routing
• Filter configuration

The actual EMC performance depends on the complete installation rather than the drive alone.

---

19. Product Introduction

The 20G11NE011JA0NNNNN is designed as a flexible industrial motor-control solution.

Its primary function is to convert incoming AC electrical power into a controlled output suitable for an AC motor.

By adjusting the output conditions, the drive can control motor speed and torque according to machine requirements.

Compared with a conventional motor starter, an AC drive offers significantly greater control.

A basic starter primarily turns the motor on or off.

A variable frequency drive can provide:

• Adjustable speed
• Controlled acceleration
• Controlled deceleration
• Motor protection functions
• Operating feedback
• Fault information
• Network communication
• Process integration

This makes the drive appropriate for machines where motor speed is an important part of the process.

---

20. Typical Applications

Application	Suitability	Main Reason
Conveyors	Excellent	Adjustable speed and smooth starting
Pumps	Excellent	Flow and pressure control
Fans	Excellent	Airflow adjustment

Material Handling	Excellent	Controlled acceleration and stopping
Processing Machinery	Very Good	Flexible motor operation
Mixers	Good	Variable-speed operation
Production Lines	Excellent	Network integration
Machine Auxiliary Drives	Excellent	Centralized control
Industrial Utility Equipment	Very Good	Adjustable motor speed

---

21. Conveyor Applications

Conveyor systems frequently require controlled speed.

A fixed-speed motor can limit production flexibility.

With the 20G11NE011JA0NNNNN, the conveyor motor can be operated at different speeds depending on the production process.

Potential benefits include:

• Adjustable conveyor speed
• Smooth startup
• Smooth stopping
• Reduced mechanical shock
• Network control
• Speed reference from the controller
• Fault monitoring
• Current monitoring
• Easier integration with automated production lines

For conveyors with significant inertia, the dynamic-braking function can also be valuable.

---

22. Pump Applications

Pumps are often required to operate at different flow rates.

Variable-speed control can allow the motor to operate closer to the actual process requirement.

Potential applications include:

• Industrial water systems
• Cooling-water systems
• Process circulation
• Transfer pumps
• Utility systems
• Fluid-handling systems

The drive can receive speed commands from a control system and return operating information for monitoring.

---

23. Fan and Blower Applications

Fans and blowers often do not need to operate at full speed continuously.

A variable-speed drive can provide a controlled operating point.

Applications include:

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

The exact energy benefit depends on the fan curve, operating profile, motor efficiency, and process requirements.

---

24. Feeder Applications

Industrial feeders often require controlled material flow.

The drive can regulate the motor speed and therefore influence the material-feed rate.

Typical applications include:

• Material feeders
• Production feeders
• Packaging feeders
• Conveyor feeders
• Processing equipment
• Bulk-material systems

This can provide a more flexible solution than using fixed mechanical speed ratios.

---

25. Packaging Applications

Packaging machines often contain several motors that need to operate in coordination.

The drive can be used for:

• Product conveyors
• Feed rollers
• Transport mechanisms
• Auxiliary drive sections
• Material handling
• Machine sections requiring adjustable speed

Network communication can allow a central controller to modify the speed reference while monitoring the drive’s operating state.

---

26. Material Handling Applications

Material-handling equipment benefits from controlled acceleration and deceleration.

Examples include:

• Transfer conveyors
• Sorting equipment
• Production conveyors
• Feed mechanisms
• Material transport systems
• Automated handling equipment

The ability to monitor current and fault status can also be useful for maintenance.

---

27. Main Product Advantages

27.1 11 A Current Rating

The 11 A output-current class provides a useful capacity range for industrial motors.

It can cover applications that are beyond the range of smaller drives while remaining substantially smaller than high-current industrial units.

---

27.2 600 VAC Capability

The 600 VAC class makes this model suitable for industrial power systems designed around higher three-phase voltage.

---

27.3 10 HP Normal-Duty Rating

The normal-duty rating reaches approximately 10 HP.

This makes the model suitable for many general-purpose industrial motor applications.

---

27.4 7.5 HP Heavy-Duty Rating

For more demanding applications, the heavy-duty rating is approximately 7.5 HP.

This gives the user a useful reference when evaluating higher-torque loads.

---

27.5 Embedded Ethernet/IP

The embedded Ethernet/IP capability allows the drive to be integrated into a networked automation architecture.

---

27.6 Dynamic-Braking Transistor

The integrated braking transistor simplifies the drive configuration for applications requiring dynamic braking.

---

27.7 EMC Filtering

The filtered configuration can help with electromagnetic compatibility when installed correctly.

---

27.8 Forced-Air Cooling

Forced-air cooling provides a practical method of removing heat from the power electronics.

---

Drive status, current, frequency, alarms, and faults can be used for troubleshooting and maintenance.

---

27.10 Flexible Machine Integration

The PowerFlex 755 platform is suitable for applications where the drive is part of a larger automation system.

---

---

30. Installation Requirements

A suitable installation should provide adequate:

• Ventilation
• Electrical protection
• Grounding
• Cable separation
• Service access
• Thermal management
• Environmental protection

The drive should be installed in a suitable enclosure where it is protected from environmental conditions outside its rated installation environment.

Particular attention should be given to cabinet temperature.

High ambient temperature can reduce the available drive capacity and may shorten component life.

---

31. Motor Cable and EMC Considerations

VFD motor wiring should be treated differently from ordinary low-voltage control wiring.

The switching operation of the drive can produce high-frequency electrical noise.

The installation should consider:

• Appropriate motor cable
• Cable shielding
• Short and controlled cable routing
• Proper grounding
• Cabinet bonding
• Separation from analog signals
• Separation from communication wiring
• Proper motor-frame grounding
• Appropriate EMC installation practices

These measures are important when the drive is installed close to PLCs, communication devices, sensors, encoders, and other sensitive electronic equipment.

---

32. Communication and Automation

The drive can be viewed as one component in a complete automation system.

A typical arrangement can be represented as:

Controller → Ethernet/IP Network → Drive → Motor

The controller can send:

• Start command
• Stop command
• Speed reference
• Direction command
• Enable command
• Reset command

The drive can return:

• Running status
• Speed
• Current
• Frequency
• Fault information
• Alarm information
• Drive condition

This architecture reduces the need for independent hardwired control for every drive function.

---

33. Maintenance Advantages

The drive’s monitoring capabilities can assist maintenance personnel.

For example, increasing motor current may indicate:

• Mechanical overload
• Bearing problems
• Conveyor blockage
• Pump problems
• Incorrect process conditions
• Incorrect motor parameters

Repeated drive faults may also indicate:

• Power-quality problems
• Excessive acceleration demand
• Excessive deceleration demand
• Motor problems
• Thermal problems
• Communication issues

The drive therefore provides useful information for troubleshooting beyond simply indicating whether a motor is running.

---

34. Energy Management

A variable frequency drive can help a machine operate at a speed appropriate for the actual process requirement.

This can be particularly useful for:

• Fans
• Blowers
• Pumps
• Circulation systems
• Ventilation equipment

Instead of continuously operating at maximum speed, the motor can operate at a lower speed when the process requires less output.

Actual energy savings depend on the machine design, load characteristics, operating hours, motor efficiency, and control strategy.

---

39. Difference Between the 20G11NE011JA0NNNNN and 480 VAC Models

A particularly important point is the voltage class.

The 20G11NE011JA0NNNNN is a 600 VAC class model.

A similarly numbered 480 VAC model is not automatically an interchangeable replacement.

For example, a 480 VAC drive may have a similar current rating but still be unsuitable for a 600 VAC supply.

The following must be checked:

Selection Factor	20G11NE011JA0NNNNN
Supply Voltage	600 VAC class
Phase	3 Phase
Current	11 A
Normal Duty	10 HP
Heavy Duty	7.5 HP
Motor Voltage	Must match application
Input Protection	Must be correctly selected
Motor Current	Must remain within drive capability

Voltage compatibility should always be verified before substitution.

---

40. Difference Between Normal Duty and Heavy Duty

The distinction between normal duty and heavy duty is important when choosing this drive.

A normal-duty application may involve a relatively stable load with moderate overload requirements.

A heavy-duty application may require greater torque and more severe overload capability.

Examples of potentially more demanding loads include:

• Loaded conveyors
• Mixers
• Crushers
• High-inertia machinery
• Material-handling equipment
• Machines with frequent acceleration
• Machines with frequent deceleration

The fact that the drive is rated at 10 HP normal duty does not mean that every 10 HP motor application is appropriate.

For demanding applications, the 7.5 HP heavy-duty rating is the more conservative reference.

---

41. Advantages for Machine Builders

The 20G11NE011JA0NNNNN provides a good balance between drive capacity and control functionality.

Machine builders can use it where the design requires:

• Adjustable motor speed
• Controlled startup
• Controlled stopping
• Network communication
• Drive diagnostics
• Industrial cabinet installation
• Dynamic braking
• Motor-current monitoring

The absence of a local HIM can also be useful when the machine already has a centralized operator interface.

---

42. Advantages for Automation Engineers

Automation engineers can integrate the drive into a larger control system.

A typical control architecture can include:

PLC / Controller

↓

Ethernet/IP Network

↓

20G11NE011JA0NNNNN

↓

Three-Phase AC Motor

This allows the drive to function as an intelligent motor-control node rather than simply an independent power device.

---

43. Advantages for Maintenance Teams

Maintenance personnel can use drive operating information to assist troubleshooting.

Useful information can include:

• Drive running status
• Motor current
• Output frequency
• Fault condition
• Alarm condition
• Network condition
• Operating state

This information can reduce the time required to identify whether the problem is electrical, mechanical, control-related, or process-related.

---

44. Advantages for Production Systems

In production environments, adjustable motor speed can improve process flexibility.

For example, the same machine may require:

• High speed during normal production
• Low speed during setup
• Reduced speed during product changeover
• Controlled acceleration after startup
• Controlled deceleration before stopping

The drive can support these different operating requirements without mechanically changing the motor’s fixed-speed arrangement.

47. Overall Product Assessment

The 20G11NE011JA0NNNNN is a practical choice for industrial motor-control systems where an approximately 11 A drive is required and the incoming electrical system is in the 600 VAC class.

Its combination of 10 HP normal-duty capacity, 7.5 HP heavy-duty capacity, embedded Ethernet/IP, forced-air cooling, dynamic-braking capability, EMC filtering, and Frame 3 construction gives it a broad application range.

It is particularly attractive for industrial equipment that needs centralized control and monitoring.

The model is not simply a basic speed controller.

It can function as part of an integrated machine-control architecture where motor speed, operating status, current, faults, and commands are exchanged between the drive and the main automation system.

49. Conclusion

The 20G11NE011JA0NNNNN is best understood as a medium-capacity industrial PowerFlex 755 variable frequency drive designed for demanding three-phase motor-control applications.

Its 600 VAC input class and 11 A output rating make it suitable for a different electrical environment from comparable 480 VAC models.

The 10 HP normal-duty and 7.5 HP heavy-duty ratings provide flexibility for different load conditions, while the embedded Ethernet/IP communication makes the drive suitable for modern networked automation systems.

The Frame 3 construction, forced-air cooling, EMC filtering, dynamic-braking transistor, and open-type cabinet installation provide a practical configuration for industrial machinery.

For applications involving conveyors, pumps, fans, blowers, feeders, packaging equipment, material handling, and general production machinery, this model offers a combination of adjustable speed control and automation-system integration.

When selecting this model for a real installation, the most important checks are the 600 VAC supply, three-phase configuration, motor nameplate current, normal-duty or heavy-duty requirement, braking requirement, environmental conditions, cabinet cooling, communication requirements, and physical installation space.

The approximate physical reference for planning is 424 × 170 × 212 mm, with an approximate drive weight of 6.8 kg. These mechanical values should be treated as planning figures, while the actual installation should use the specific mechanical dimensions associated with the unit being installed.
