Allen-Bradley 20G11TD617JN0NNNNN PowerFlex 755 AC Drive – Detailed Product Specifications, Applications, Advantages and Related Models

1. Product Introduction

The Allen-Bradley 20G11TD617JN0NNNNN is a high-power PowerFlex 755 AC Drive designed for large industrial motor-control applications where high current capacity, reliable variable-speed operation, flexible control, and industrial network integration are required.

This model is part of the PowerFlex 755 series and is designed for a 480 VAC, three-phase power system. It uses a large Frame 8 construction and provides a rated output current of 617 A.

The drive is rated for approximately 600 HP in Light-Duty applications, 500 HP in Normal-Duty applications, and 400 HP in Heavy-Duty applications. This makes it suitable for a broad range of large industrial machinery, including pumps, fans, compressors, conveyors, material-handling systems, mining equipment, cement machinery, and other high-power motor-driven equipment.

The 20G11TD617JN0NNNNN uses an air-cooled / forced-air cooling system, an open-type construction, embedded Ethernet/IP communication, an AC input with precharge, and DC terminals. Its input configuration also includes filtering with the CM jumper installed, which is an important configuration characteristic of this particular catalog number.

The model is supplied in a blank configuration without a HIM. This allows the drive to be incorporated into a larger automation system where control and monitoring are handled through an industrial controller, HMI, network, or other system-level interface.

The 20G11TD617JN0NNNNN is therefore not simply a general-purpose frequency inverter. It is a large industrial drive intended to form part of a complete motor-control and automation system.

The 480 VAC three-phase configuration is commonly used in large industrial electrical systems.

The 617 A rating places this model firmly in the high-power category. It is intended for applications where smaller compact drives would not provide sufficient current capacity.

The Normal-Duty rating of 500 HP is especially useful for applications involving large continuously operating motors with moderate overload requirements.

For more demanding applications involving high starting torque or substantial cyclic overload, the Heavy-Duty rating of 400 HP should be used as the more conservative selection reference.

5. Duty Ratings Explained

Light Duty – 600 HP

The Light-Duty rating is approximately 600 HP.

Light-Duty applications generally have comparatively moderate overload requirements. Typical examples include large centrifugal fans and centrifugal pumps where the mechanical load characteristics are relatively predictable.

For these applications, the 600 HP rating provides a very high level of motor-control capacity while retaining the advantages of variable-speed operation.

Normal Duty – 500 HP

The Normal-Duty rating is 500 HP.

This is one of the most important ratings when considering this drive for general industrial machinery.

Normal-Duty applications may include:

• Large pumps
• Large fans
• Blowers
• Conveyors
• Process machinery
• Compressors
• Material-handling equipment
• Industrial production equipment

The 500 HP Normal-Duty rating provides a practical reference point for selecting the drive for large industrial motors.

Heavy Duty – 400 HP

The Heavy-Duty rating is approximately 400 HP.

Heavy-Duty applications normally require greater overload capability or experience more severe mechanical conditions.

Examples can include:

• Crushers
• Heavy conveyors
• High-inertia machines
• Large mixers
• Material-processing machinery
• Cyclic industrial machinery
• Heavy-duty production equipment

When a machine has a difficult starting condition or regularly experiences high torque demand, the Heavy-Duty rating should receive particular attention during sizing.

6. Physical Dimensions and Weight

The physical size of this drive is an important consideration because it belongs to the large Frame 8 class.

Mechanical Parameter	Approximate Value
Model	20G11TD617JN0NNNNN
Frame Size	Frame 8
Approx. Width	720 mm
Approx. Height	2185 mm
Approx. Depth	650 mm
Approx. Overall Dimensions	720 × 2185 × 650 mm
Approx. Weight	335 kg
Cooling Method	Forced Air
Construction	Open Type
Installation	Industrial cabinet / electrical room
Handling Requirement	Mechanical lifting recommended
Service Clearance	Large equipment access required

The dimensions and weight should be treated as approximate reference values. The exact overall dimensions can vary depending on the final mechanical arrangement, installation configuration, ducting, cabinet design, and associated equipment.

For detailed engineering work, the exact dimensional drawing for the selected configuration should always be used.

At approximately 335 kg, this drive should be treated as heavy electrical equipment. Transportation, lifting, mounting structure, floor loading, cabinet construction, and maintenance access should all be considered during installation planning.

7. Construction and Cooling

The 20G11TD617JN0NNNNN uses a Frame 8 open-type construction with forced-air cooling.

Large industrial drives generate substantial heat during operation. Proper airflow is therefore an important part of system reliability.

The installation should provide adequate:

• Air intake
• Air exhaust
• Cabinet ventilation
• Heat dissipation
• Service clearance
• Fan access
• Dust management

Air should not be allowed to recirculate excessively from the hot exhaust side back into the cooling-air intake.

For industrial environments with significant dust or contamination, cabinet filtration and maintenance practices become particularly important.

8. Embedded Ethernet/IP Communication

One of the major advantages of the PowerFlex 755 platform is its industrial communication capability.

The 20G11TD617JN0NNNNN incorporates embedded Ethernet/IP.

This allows the drive to become part of a larger automation network.

A typical control system can include:

Equipment	Typical Function
20G11TD617JN0NNNNN	Large motor speed and torque control
PLC	Machine and process control
HMI	Operator monitoring and command
Ethernet/IP Network	Drive communication
Sensors	Process feedback
SCADA	Plant-level monitoring
MCC	Motor power distribution
Safety System	Safety-related functions
Motor	Mechanical power output

The drive can therefore be integrated into a centralized industrial control structure instead of operating as an isolated inverter.

9. AC Input with Precharge

The 20G11TD617JN0NNNNN uses an AC input with precharge configuration.

Precharge is particularly important in large drives because the DC bus contains substantial capacitive energy storage.

During energization, controlled charging of the DC bus helps manage the initial charging current.

This is an important feature in high-power drive systems because the electrical energy involved is considerably greater than that found in small compact drives.

10. DC Terminals

The model includes DC terminals.

This provides additional flexibility for drive-system architecture and can be useful when a project involves DC-bus arrangements or coordinated drive systems.

However, the availability of DC terminals does not automatically mean that an external common DC-bus system should be used.

The actual application should determine whether the DC terminals are required and how they should be integrated into the overall electrical design.

11. Filtering and CM Jumper

The 20G11TD617JN0NNNNN is specified as:

• Filtered
• CM jumper installed
• Preferred CM configuration

This is one of the details that distinguishes this configuration from some earlier catalog versions.

A related legacy configuration, 20G11TD617AN0NNNNN, used the same major current and horsepower ratings but had the CM jumper removed.

The JN configuration therefore should not be treated as merely a cosmetic catalog-number change. The configuration of the CM jumper is part of the electrical installation characteristics and should be considered during replacement or retrofit work.

12. No HIM Configuration

The catalog number specifies a Blank / No HIM configuration.

This means the drive does not include a standard HIM operator interface as part of this base configuration.

For automated industrial systems, this can be perfectly practical because drive operation can instead be handled through:

• PLC control
• Ethernet/IP communication
• HMI
• SCADA
• External control devices
• Engineering software

For applications where local operator access is important, the system designer can select the appropriate operator-interface arrangement separately.

13. Product Applications

Large Industrial Pumps

The 20G11TD617JN0NNNNN is well suited to large pump applications.

Typical applications include:

• Water treatment
• Industrial water circulation
• Cooling-water systems
• Process pumping
• Irrigation
• Wastewater systems
• Chemical-process pumping
• Mining water management

Variable-speed control allows pump output to be adjusted according to process demand.

This can provide better process control and potentially reduce energy consumption compared with continuously operating a motor at full speed.

Large Fans

Large industrial fans can also benefit from variable-speed operation.

Typical applications include:

• Industrial ventilation
• Furnace systems
• Cooling towers
• Exhaust systems
• Dust collection
• Combustion-air systems
• Mine ventilation
• Process-air systems

The drive can regulate motor speed according to the required airflow.

Large Conveyors

Conveyors are another major application area.

Potential applications include:

• Mining conveyors
• Cement conveyors
• Aggregate handling
• Bulk material systems
• Port equipment
• Steel plants
• Material-processing plants

Variable-speed control can provide controlled acceleration and deceleration.

This can help reduce mechanical shock and improve material-handling performance.

Mining Equipment

The high current rating makes the PowerFlex 755 platform particularly relevant to large mining equipment.

Possible applications include:

• Ore conveyors
• Crushers
• Large pumps
• Mine ventilation
• Material handling
• Processing equipment
• Auxiliary machinery

Mining applications can involve high inertia, variable loads, harsh operating cycles, and continuous operation, making high-power industrial drive architecture particularly useful.

Cement Plants

Large cement and aggregate facilities frequently use large variable-speed motors.

Possible applications include:

• Crushers
• Conveyors
• Fans
• Pumps
• Feeders
• Processing machinery
• Material-handling systems

The drive’s high current capacity makes it appropriate for large motors used in these processes.

Steel and Metal Processing

The drive can also be considered for large steel and metal-processing machinery.

Applications may include:

• Process fans
• Cooling pumps
• Material handling
• Production-line equipment
• Auxiliary machinery
• Large rotating equipment

The Ethernet/IP capability can also simplify integration with a plant-wide control system.

Compressors

Large compressors can require high motor current and controlled acceleration.

The PowerFlex 755 platform can be used for suitable compressor applications where the motor and compressor characteristics are compatible with the drive’s ratings.

Compressor selection should always consider starting torque, operating speed range, mechanical inertia, pressure requirements, and process control requirements.

14. Product Advantages

1. High 617 A Current Capacity

The most obvious advantage of this model is its 617 A output-current class.

This allows it to control very large motors that are far beyond the range of compact general-purpose drives.

2. 500 HP Normal-Duty Capability

The 500 HP Normal-Duty rating provides substantial capacity for large industrial machinery.

This makes the drive particularly useful for large pumps, fans, conveyors, blowers, compressors, and processing equipment.

3. 600 HP Light-Duty Capability

For applications with relatively moderate load characteristics, the drive can reach a Light-Duty rating of approximately 600 HP.

This makes the same drive platform useful across different load categories.

4. 400 HP Heavy-Duty Capability

For more demanding machinery, the drive offers a Heavy-Duty rating of approximately 400 HP.

This gives designers an appropriate reference point for higher-overload applications.

5. Embedded Ethernet/IP

The embedded communication capability makes the drive suitable for modern industrial automation.

It can be integrated into a networked control system rather than being operated as an independent motor controller.

6. Large Industrial Architecture

The PowerFlex 755 platform is intended for large industrial systems.

It provides a more appropriate architecture for high-power machinery than compact drives designed primarily for smaller motors.

7. Flexible Duty Selection

Having Light-Duty, Normal-Duty, and Heavy-Duty ratings allows engineers to match the drive to the actual mechanical load.

This is important because two motors with the same horsepower can have very different current and overload requirements.

8. Air-Cooled Design

Forced-air cooling is a practical solution for many large industrial drive installations.

It avoids the additional complexity associated with liquid cooling while providing an effective method for removing drive heat when the airflow system is correctly designed.

9. Integration into Large Automation Systems

The drive can become part of a complete automated production system.

This is especially valuable in large facilities where motor control, process control, diagnostics, and operator monitoring need to work together.

15. Recommended Applications by Suitability

Application	Suitability	Main Reason
Large Centrifugal Pump	Excellent	Variable-speed process control
Large Industrial Fan	Excellent	Airflow regulation
Large Conveyor	Excellent	Controlled acceleration and speed
Mining Conveyor	Excellent	High current and high power
Large Blower	Excellent	Variable airflow
Water Treatment Pump	Excellent	Large motor speed control
Cement Equipment	Excellent	High-power process machinery
Steel Equipment	Very Good	Large motor applications
Compressor	Good	Requires application-specific sizing
Crusher	Good	Requires heavy-duty evaluation
Hoist	Application Dependent	Braking and regenerative requirements
Regenerative Load	Application Dependent	Base model has no dynamic braking
Small Machinery	Not Recommended	Drive is oversized for the application

16. Important Consideration: Dynamic Braking

The catalog configuration specifies Dynamic Braking: None.

This is an important point for applications where the motor must decelerate rapidly or where the mechanical load can return energy to the drive.

Applications such as:

• High-inertia machinery
• Hoists
• Certain conveyors
• Rapid cycling equipment
• Large rotating machinery

may require additional braking or regenerative-energy management.

The absence of an internal dynamic-braking configuration does not mean that the drive cannot be used in these applications, but the complete braking architecture must be engineered separately.

17. Same-Series Recommended Models

The following models are closely related PowerFlex 755 configurations in the same high-power 480 VAC class.

Model	Voltage	Current	Light Duty	Normal Duty	Heavy Duty	Frame
20G11TD430JN0NNNNN	480 VAC, 3 PH	430 A class	400 HP	350 HP	300 HP	8
20G11TD485JN0NNNNN	480 VAC, 3 PH	485 A class	450 HP	400 HP	350 HP	8
20G11TD545JN0NNNNN	480 VAC, 3 PH	545 A class	500 HP	450 HP	350 HP	8
20G11TD617JN0NNNNN	480 VAC, 3 PH	617 A	600 HP	500 HP	400 HP	8
20G11TD710JN0NNNNN	480 VAC, 3 PH	710 A class	650 HP	600 HP	450 HP	8

These models provide a useful progression when selecting a high-power PowerFlex 755 drive.

The 20G11TD430JN0NNNNN is suitable for a lower current requirement, while the 20G11TD710JN0NNNNN moves into an even higher current and horsepower class.

The 20G11TD617JN0NNNNN is therefore a strong middle-to-high capacity choice for systems requiring approximately 500 HP Normal-Duty capability.

18. Same-Series Comparison with Dimensions and Weight

Model	Voltage	Current	LD	ND	HD	Frame	Approx. Dimensions	Approx. Weight
20G11TD430JN0NNNNN	480 VAC	430 A class	400 HP	350 HP	300 HP	8	Large Frame 8	Approx. 300–335 kg
20G11TD485JN0NNNNN	480 VAC	485 A class	450 HP	400 HP	350 HP	8	Large Frame 8	Approx. 300–335 kg
20G11TD545JN0NNNNN	480 VAC	545 A class	500 HP	450 HP	350 HP	8	Large Frame 8	Approx. 300–335 kg
20G11TD617JN0NNNNN	480 VAC	617 A	600 HP	500 HP	400 HP	8	Approx. 720 × 2185 × 650 mm	Approx. 335 kg
20G11TD710JN0NNNNN	480 VAC	710 A class	650 HP	600 HP	450 HP	8	Large Frame 8	Approx. 335 kg+

The physical dimensions and weights of related Frame 8 configurations should be regarded as reference values.

For cabinet design, transportation planning, and installation drawings, the exact mechanical configuration should be checked because accessories, ducting, mounting arrangements, and enclosure design can change the final dimensions.

19. Five Related High-Power PowerFlex 755 Models

Model	Voltage	Current Class	LD Rating	ND Rating	HD Rating	Frame	Approx. Dimensions	Approx. Weight
20G11TD430JN0NNNNN	480 VAC	430 A	400 HP	350 HP	300 HP	8	Large Frame 8	Approx. 300–335 kg
20G11TD485JN0NNNNN	480 VAC	485 A	450 HP	400 HP	350 HP	8	Large Frame 8	Approx. 300–335 kg
20G11TD545JN0NNNNN	480 VAC	545 A	500 HP	450 HP	350 HP	8	Large Frame 8	Approx. 300–335 kg
20G11TD710JN0NNNNN	480 VAC	710 A	650 HP	600 HP	450 HP	8	Large Frame 8	Approx. 335 kg+
20G11TD740JN0NNNNN	480 VAC	740 A	700 HP	650 HP	500 HP	8	Large Frame 8	Approx. 335 kg+

The 20G11TD740JN0NNNNN is particularly interesting for applications requiring a higher power margin.

It provides approximately 700 HP Light Duty, 650 HP Normal Duty, and 500 HP Heavy Duty, making it a logical higher-capacity member of the same family.

20. Five Popular Allen-Bradley Models from Other Drive Families

The following models represent popular Allen-Bradley drive families for applications with substantially lower power requirements than the 617 A PowerFlex 755.

They should not be considered direct electrical replacements for the 20G11TD617JN0NNNNN. Instead, they are useful reference models when comparing the broader Allen-Bradley drive portfolio.

Model	Series	Voltage Class	Current Class	Phase	General Power Class	Typical Application	Approx. Dimensions / Weight
25B-D024N114	PowerFlex 525	480 VAC	24 A class	3 PH	Small / Medium	Pumps, fans, conveyors, machinery	Compact; much smaller than Frame 8
25B-D6P0N114	PowerFlex 525	480 VAC	6 A class	3 PH	Small	Small pumps, fans, conveyors	Compact; low weight
20F11NC3P4JA0NNNNN	PowerFlex 753	480 VAC	Small current class	3 PH	Small / Medium	Industrial automation	Medium frame
20F11ND077AA0NNNNN	PowerFlex 753	480 VAC	77 A class	3 PH	Medium / Large	Industrial machinery	Medium frame
25C-D043N114	PowerFlex 523	480 VAC	43 A class	3 PH	Medium	General machinery	Compact / medium

The main reason for comparing these models is to show the difference in application scale.

The PowerFlex 523 and 525 families are generally more suitable for compact machines and lower-power motors.

The PowerFlex 753 family is positioned toward more advanced industrial applications.

The PowerFlex 755 family moves into substantially larger and more demanding industrial motor applications.

21. Comparison of the Main Drive Families

Series	Representative Model	Typical Power Level	Physical Size	Typical Application
PowerFlex 523	25C-D043N114	Small / Medium	Compact	General-purpose machinery
PowerFlex 525	25B-D024N114	Small / Medium	Compact	Connected machinery
PowerFlex 753	20F11ND077AA0NNNNN	Medium / Large	Medium	Advanced industrial control
PowerFlex 755	20G11TD617JN0NNNNN	Very Large	Frame 8	High-power industrial machinery
PowerFlex 755	20G11TD740JN0NNNNN	Extremely Large	Frame 8	Very high-power applications

The 20G11TD617JN0NNNNN belongs to the high-power end of this comparison.

Its 617 A current rating means it should be selected based on a complete motor and application calculation rather than simply choosing it because the motor’s nominal horsepower appears close to the rating.

22. Application Comparison

Application	Recommended Drive Type	Reason
Small pump	PowerFlex 525	Compact and economical
Small conveyor	PowerFlex 523 / 525	Appropriate power range
Medium industrial pump	PowerFlex 753	More advanced control
Medium conveyor	PowerFlex 753	Industrial capability
Large process pump	PowerFlex 755	High current capacity
Large fan	PowerFlex 755	Large motor capability
Large mining conveyor	PowerFlex 755	High-power operation
Large cement machinery	PowerFlex 755	High current and overload capability
Large industrial compressor	PowerFlex 755	High-power motor control
Very large motor	PowerFlex 755 / 755T depending on application	High-power system architecture

23. Installation Requirements

Because the 20G11TD617JN0NNNNN is a large Frame 8 drive, installation should be planned as part of the complete electrical system.

Important considerations include:

Cabinet Space

The cabinet should provide enough room for the drive, incoming power connections, motor cables, control wiring, ventilation, service access, and associated protective equipment.

The approximate 720 × 2185 × 650 mm reference size demonstrates that this is physically large equipment.

Airflow

Adequate forced-air ventilation is essential.

The installation should avoid:

• Blocked air passages
• Excessive dust
• Hot-air recirculation
• Insufficient cabinet ventilation
• High ambient temperature

Power Distribution

The incoming electrical system should be sized appropriately for a 617 A-class drive.

The complete system design should consider:

• Disconnect equipment
• Overcurrent protection
• Short-circuit current
• Cable capacity
• Grounding
• Transformer capacity
• Voltage drop
• Motor cable length
• Installation environment

Motor Cabling

Large variable-frequency drives require careful motor-cable planning.

Considerations include:

• Conductor size
• Cable insulation
• Cable length
• Grounding
• EMC
• Common-mode currents
• Motor insulation
• Bearing protection
• Voltage drop

24. Maintenance

Maintenance is particularly important for a large air-cooled drive.

Maintenance Item	Recommended Attention
Model	20G11TD617JN0NNNNN
Cooling Fans	Inspect condition and airflow
Air Passages	Keep clean and unobstructed
Cabinet Filters	Inspect and clean regularly
Power Connections	Check for overheating and looseness
Grounding	Verify grounding integrity
Ethernet/IP	Check communication stability
Fault History	Review alarms and trips
Motor	Inspect motor condition
Cables	Inspect insulation and terminals
Cabinet Temperature	Monitor operating temperature
Spare Parts	Maintain critical spare strategy

For a high-power drive, preventive maintenance can be particularly valuable because an unexpected drive failure can stop a large production process.

25. Advantages for Industrial Automation

The 20G11TD617JN0NNNNN offers several advantages when used in a modern automated production environment.

First, its large current capacity allows it to control motors that would be beyond the range of compact drives.

Second, its embedded Ethernet/IP capability allows the drive to communicate directly with the automation system.

Third, the PowerFlex 755 architecture is suitable for applications requiring more sophisticated drive control and diagnostics.

Fourth, the three duty classifications provide greater flexibility during drive selection.

Fifth, the Frame 8 architecture is designed for large industrial systems where motor power and electrical capacity are major design considerations.

26. Advantages for System Integrators

For system integrators, this model can be useful because the drive can be treated as one part of a complete automation architecture.

A typical system can include:

Incoming Power → Protection → 20G11TD617JN0NNNNN → Motor → Mechanical Load

while the control system operates through:

PLC → Ethernet/IP → Drive

and the operator interface can operate through:

HMI / SCADA → Industrial Network → Drive

This structure can simplify centralized monitoring and control of large motors.

27. Advantages for Large Continuous-Process Plants

Large process plants often operate continuously for long periods.

In such environments, motor-control equipment must be selected not only for nominal power but also for:

• Reliability
• Thermal management
• Maintainability
• Communication
• Diagnostics
• Spare-parts strategy
• Process integration
• Load characteristics

The PowerFlex 755 platform is well suited to this type of system-level approach.

Medium industrial motor	PowerFlex 753
Large industrial motor	PowerFlex 755
Very high-power system	PowerFlex 755 / 755T depending on requirements

This guide is intended as a general selection reference.

The final drive should always be sized according to the motor’s actual current and application duty rather than horsepower alone.

29. Key Differences Between 20G11TD617JN0NNNNN and 20G11TD617AN0NNNNN

Parameter	20G11TD617JN0NNNNN	20G11TD617AN0NNNNN

Voltage	480 VAC, 3 PH	480 VAC, 3 PH
Current	617 A	617 A
Light Duty	600 HP	600 HP
Normal Duty	500 HP	500 HP
Heavy Duty	400 HP	400 HP
Frame	8	8
Cooling	Forced Air	Air Cooled
Filtering	Filtered	Filtered
CM Jumper	Installed	Removed
Dynamic Braking	None	None
HIM	No HIM	No HIM
DC Terminals	Yes	Yes
Main Difference	CM jumper installed	CM jumper removed

The two catalog numbers have essentially the same major electrical rating, but the CM-jumper configuration is different.

This is important when replacing an existing unit.

For a new installation, the JN configuration is the more relevant configuration to consider because it is the active catalog configuration.

30. Why the JN Configuration Is Important

The JN configuration is particularly useful for customers who are replacing older PowerFlex 755 installations.

The model retains the familiar 617 A / 600 HP LD / 500 HP ND / 400 HP HD power class while using the updated configuration with the CM jumper installed.

This can make it an attractive choice for maintaining consistency in large industrial installations while moving away from an older configuration.

34. Overall Product Evaluation

The Allen-Bradley 20G11TD617JN0NNNNN is a high-capacity PowerFlex 755 AC drive intended for large industrial motors and demanding process equipment.

Its 617 A current rating, 600 HP Light-Duty rating, 500 HP Normal-Duty rating, and 400 HP Heavy-Duty rating give it considerable application flexibility.

The combination of a 480 VAC three-phase input, Frame 8 construction, forced-air cooling, embedded Ethernet/IP, AC input with precharge, DC terminals, filtered configuration, and installed CM jumper makes it particularly suitable for large automated industrial systems.

The model is especially attractive for large pumps, fans, conveyors, mining equipment, cement machinery, compressors, water-treatment equipment, steel-processing systems, and other applications where a compact general-purpose drive would not provide sufficient current capacity.

Its physical size and approximately 335 kg weight also need to be taken seriously during system design. This is large industrial electrical equipment and should be planned together with the cabinet, cooling system, incoming power, motor cabling, protection equipment, grounding system, lifting equipment, and maintenance access.

For an existing installation, the catalog number is particularly useful when identifying the correct replacement configuration. For a new system, the drive should be selected according to actual motor current, duty classification, load characteristics, braking requirements, operating environment, and automation architecture.

Overall, the 20G11TD617JN0NNNNN is best regarded as a high-power, network-integrated industrial motor-control solution rather than a basic variable-frequency inverter. Its strongest selling points are its high current capacity, large motor capability, flexible duty ratings, industrial Ethernet/IP communication, and suitability for large-scale automated production systems.
