6. Output Current
The key electrical characteristic of the 20G11NE011AA0NNNNN is its approximately 11 A output-current class.
Output current is more important than horsepower alone when selecting a variable frequency drive.
For final selection, the motor’s nameplate current should be compared with the applicable drive rating.
A motor may have a nominal horsepower rating that appears suitable while still requiring a larger drive because of:
- High starting torque
- High inertia
- Frequent acceleration
- Frequent deceleration
- High ambient temperature
- Continuous overload
- Rapid cycling
- Process-specific torque requirements
Therefore, the 11 A rating should be treated as an important selection parameter rather than using horsepower as the only criterion.
7. Motor Capacity
The drive is generally associated with the approximately 7.5 HP / 5.5 kW motor class for a 480 VAC industrial application.
A typical application range can include:
| Motor Class | Suitability |
|---|---|
| 3 HP | More than sufficient capacity |
| 5 HP | Suitable depending on motor current |
| 7.5 HP | Primary application range |
| 10 HP | Requires careful current/duty verification |
| Above 10 HP | Normally consider a larger current-rated drive |
The actual motor current, load torque, overload requirements, speed range, and duty cycle should determine the final selection.
8. Voltage Class
The 20G11NE011AA0NNNNN is associated with the 480 VAC class.
This makes it suitable for industrial three-phase power systems designed around the 480 V class.
Typical industrial environments where this voltage class is encountered include:
- Manufacturing plants
- Process facilities
- Material-handling systems
- Packaging plants
- Pumping systems
- HVAC equipment
- Production machinery
- Machine tools
Correct input-voltage compatibility should always be verified before installation.
9. Three-Phase Operation
The drive is intended for three-phase industrial motor control.
Three-phase AC drives are widely used because they provide efficient control of three-phase induction motors and other compatible AC motors.
The drive regulates motor operation by controlling the electrical output delivered to the motor.
This enables the machine to operate at different speeds instead of relying only on fixed-frequency operation.
10. Variable-Speed Operation
One of the main purposes of the drive is to provide adjustable motor speed.
Instead of operating the motor continuously at one fixed speed, the controller can command different operating speeds according to process requirements.
Typical examples include:
- Low speed during setup
- Medium speed during normal production
- High speed during peak production
- Controlled speed during material transfer
- Reduced speed during positioning
- Controlled deceleration during stopping
This flexibility is particularly valuable in automated machinery.
11. Acceleration and Deceleration Control
The drive can control the rate at which the motor accelerates and decelerates.
This provides several practical advantages.
A conveyor, for example, does not necessarily need to reach full speed immediately.
A controlled acceleration ramp can reduce mechanical shock to:
- Gearboxes
- Couplings
- Shafts
- Belts
- Chains
- Rollers
- Product materials
Likewise, controlled deceleration can reduce abrupt mechanical loading during stopping.
12. Dynamic Braking
The PowerFlex 755 platform can support dynamic braking configurations.
Dynamic braking is useful when a machine has significant rotating inertia or requires relatively rapid stopping.
During motor deceleration, mechanical energy can be returned to the drive’s DC bus.
The braking system can then dissipate this energy through an appropriate braking resistor arrangement.
Typical applications include:
- Conveyors
- Feeders
- High-inertia machinery
- Material-handling equipment
- Packaging machinery
- Machines with frequent stopping
- Machinery requiring controlled deceleration
The braking resistor must be correctly selected for the actual application.
13. EtherNet/IP Communication
The drive is designed for integration into industrial Ethernet-based automation systems.
Network communication can allow the control system to exchange information such as:
| Data | Typical Function |
|---|---|
| Start Command | Starts the motor |
| Stop Command | Stops the motor |
| Speed Reference | Sets desired motor speed |
| Direction | Controls rotation direction |
| Output Frequency | Monitors operating speed |
| Output Current | Monitors motor load |
| Drive Status | Determines operating condition |
| Fault Status | Identifies drive faults |
| Alarm Status | Indicates abnormal conditions |
| Reset Command | Resets appropriate faults |
| Parameter Information | Configuration and monitoring |
This makes the drive suitable for centralized machine control.
14. Product Introduction
The 20G11NE011AA0NNNNN is an industrial variable frequency drive intended to provide controlled AC motor operation.
In a conventional fixed-speed motor installation, a motor may run at approximately one operating speed whenever it is energized.
An AC drive introduces another level of control.
The drive can vary the electrical frequency supplied to the motor and adjust other motor-control parameters, allowing the motor to operate over a controlled speed range.
This can improve the machine’s flexibility and make motor operation more closely match the actual process requirement.
The PowerFlex 755 architecture also allows the drive to be integrated into a larger automation system.

35. Advantages for Machine Builders
For machine builders, this drive provides several useful characteristics.
Compact Industrial Solution
The drive provides considerable control functionality within a relatively compact cabinet-mounted package.
Network Integration
The drive can communicate with the machine’s control system.
Adjustable Speed
Machine speed can be changed through the drive rather than requiring mechanical changes.
Controlled Acceleration
The motor can be started progressively.
Controlled Deceleration
The motor can be stopped according to a programmed ramp.
Diagnostics
Operating and fault information can assist machine troubleshooting.
Flexible Applications
The same basic drive platform can be used across many machine types.
36. Advantages for Automation Engineers
Automation engineers can benefit from the drive’s ability to participate in a centralized control architecture.
Typical architecture:
Controller → Industrial Ethernet → Drive → Motor
The controller can issue:
- Start commands
- Stop commands
- Speed references

- Reset commands
At the same time, the drive can return:
- Status
- Speed
- Current
- Faults
- Alarms
This provides two-way communication between the motor-control system and the machine controller.
37. Advantages for Maintenance Personnel
Maintenance personnel benefit from access to drive status and diagnostic information.
Instead of checking only whether the motor is running, a maintenance technician can examine information such as:
- Output current
- Operating frequency
- Fault status
- Alarm status
- Drive state
- Network condition
This can help identify the difference between an electrical problem and a mechanical process problem.
38. Energy and Process Control Benefits
Variable-speed operation can help a machine avoid unnecessary full-speed operation.
This is particularly relevant for:
- Fans
- Blowers
- Pumps
- Circulation systems
- Air-handling equipment
The actual energy savings depend on the machine, process, load profile, motor efficiency, operating hours, and control strategy.
The drive itself should therefore be viewed as an enabling technology for process optimization rather than assuming a fixed energy-saving percentage.

44. Final Product Summary
The 20G11NE011AA0NNNNN is a PowerFlex 755 industrial AC variable frequency drive in the 480 VAC class with an approximately 11 A output-current rating.
It is primarily suited to motor applications around the 7.5 HP / 5.5 kW class, provided the motor nameplate current and application duty are compatible with the drive rating.
The drive is suitable for a wide range of industrial equipment, including conveyors, pumps, fans, blowers, feeders, packaging machinery, material-handling systems, and general production machinery.
Its main strengths are the combination of adjustable-speed motor control, industrial networking, diagnostic functions, controlled acceleration and deceleration, dynamic-braking capability, and flexible integration into automated control systems.
For an application where a smaller 5 A or 8 A drive does not provide enough current capacity, the 11 A class is a practical next step.
For larger motor loads, the 15 A, 22 A, or higher-current PowerFlex 755 models should be considered.
