20G11BE980JN0NNNNN Product Detailed Specification, Introduction, Applications, Advantages and Model Recommendations

1. Product Overview

The 20G11BE980JN0NNNNN is a high-power air-cooled AC variable frequency drive belonging to the PowerFlex 755 series within the PowerFlex 750 Series family.

It is designed for large industrial motor applications where high output current, controlled acceleration, adjustable motor speed, process control, and industrial network integration are required.

With a 980 A current rating and a 600 VAC class, this model is positioned at the very high end of the PowerFlex 755 range. It is intended for large motors used in heavy industrial equipment such as pumps, fans, compressors, conveyors, mixers, material-handling systems, mining equipment, and other large process machinery.

The 20G11BE980JN0NNNNN is particularly notable because it is an active configuration associated with the replacement path for the earlier 20G11BE980AN0NNNNN model.

---

2. Brand and Product Series

The most important point when identifying this product is that 20G11BE980JN0NNNNN is not simply a generic 980 A inverter. It is a specific catalog configuration containing defined voltage, enclosure, filtering, cooling, communication, braking, and physical installation characteristics.

---

3. Main Technical Parameters

The physical dimensions and weight should be regarded as cabinet-level engineering values rather than a universal shipping dimension for every possible installation. Large Frame 9 equipment can have differences caused by cabinet arrangements, power connections, accessories, mounting arrangements, and factory-installed options.

For transportation, lifting, foundation design, and floor-loading calculations, the actual equipment drawing and shipping data for the specific unit should always take precedence.

---

4. Electrical Performance

The 20G11BE980JN0NNNNN is rated at 980 A, which is its most significant electrical characteristic.

This current capacity places the unit in the very large industrial drive category. It is suitable for motors requiring extremely high current compared with conventional small and medium-sized variable-frequency drives.

The model is rated for approximately 1,100 HP under Low Duty, 1,000 HP under Normal Duty, and 900 HP under Heavy Duty.

The distinction between these duty classifications is important.

A motor that operates under relatively light and stable torque conditions may be able to use the higher Low Duty horsepower rating. A motor with higher continuous torque, frequent acceleration, or demanding overload conditions may require the lower Heavy Duty rating.

Therefore, the drive should not be selected based solely on the motor horsepower shown on a nameplate. The actual current, torque profile, acceleration requirement, overload requirement, and operating cycle should also be considered.

---

5. Duty Rating Explanation

The Heavy Duty rating is particularly important for applications such as heavy conveyors, crushers, loaded material-handling equipment, positive-displacement machinery, and other systems where the motor can experience substantial torque demand.

For a centrifugal fan or pump, the Low Duty rating may be more relevant because the torque characteristic is generally more favorable.

---

6. Product Introduction

The 20G11BE980JN0NNNNN is a large industrial AC drive intended to regulate the speed and torque of high-power three-phase motors.

Instead of connecting a motor directly to the electrical supply and allowing it to operate primarily at the fixed supply frequency, the drive generates a controlled output waveform and regulates the motor’s operating speed.

This makes it possible to match motor speed more closely to the actual production requirement.

For example, a large pump does not necessarily need to operate at full speed throughout the entire day. With variable-speed control, the motor speed can be adjusted as the required flow changes.

Similarly, a conveyor may need different speeds during different production stages, while a fan or blower may need to respond to changing airflow requirements.

The 20G11BE980JN0NNNNN is therefore not simply a motor starter. It is a high-power electronic motor-control system designed to become part of a larger industrial automation and process-control architecture.

---

7. Product Construction

The drive uses an air-cooled Frame 9 architecture.

At this power level, heat generation is considerable, so forced-air cooling is an important part of the overall system.

The physical cabinet is considerably larger than the small-frame drives used for ordinary machine tools, small conveyors, or compact production equipment.

The approximate physical class is:

The 600 mm cabinet-depth configuration is especially useful when the available electrical-room footprint is limited compared with deeper cabinet arrangements.

Nevertheless, sufficient front service access, airflow, cable routing space, and maintenance clearance must be provided.

---

8. Communication Capability

One of the important characteristics of this configuration is its embedded EtherNet/IP communication capability.

For a large industrial drive, network integration is particularly valuable because the drive is usually not operated as an isolated piece of equipment.

It can form part of a complete control system in which a programmable controller or supervisory system provides speed references, start/stop commands, status monitoring, alarms, and diagnostic information.

Typical information that may be exchanged through the industrial network includes:

This type of communication architecture can significantly reduce the need for large quantities of traditional hardwired control signals.

---

9. Product Applications

9.1 Large Industrial Pumps

Large water pumps, cooling-water pumps, process pumps, pipeline systems, and industrial circulation systems can benefit from high-power variable-speed control.

The drive allows the pump motor to operate at different speeds according to process demand.

This can be particularly valuable for variable-flow systems where operating a motor continuously at full speed would result in unnecessary energy consumption.

---

9.2 Large Fans and Blowers

Industrial fans and blowers often represent substantial electrical loads.

Applications can include:

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

The drive can adjust the motor speed to match the required airflow.

---

9.3 Heavy-Duty Conveyors

Large belt conveyors and bulk-material handling systems can require high starting torque.

Controlled acceleration can reduce sudden mechanical loading on:

• Conveyor belts
• Gearboxes
• Couplings
• Shafts
• Bearings
• Drive pulleys

The drive can also allow the conveyor speed to be adjusted according to production requirements.

---

9.4 Mining Equipment

Mining operations often contain extremely large electrical motors.

Potential applications include:

• Mine conveyors
• Crushers
• Large ventilation fans
• Slurry pumps
• Dewatering pumps
• Material-handling equipment
• Processing machinery

The 980 A capacity makes this model suitable for the high-power end of these applications.

---

9.5 Compressors

Large industrial compressors can require controlled acceleration and stable speed regulation.

A variable-frequency drive can help control compressor operating speed while reducing the mechanical shock associated with direct motor starting.

Compressor applications should be carefully evaluated because the compressor’s torque characteristics can vary significantly according to compressor technology and operating conditions.

---

9.6 Large Mixers and Agitators

Industrial mixers can experience substantial torque requirements during startup.

This is particularly true when the material being mixed is viscous or when the machine starts under load.

A high-power drive can provide controlled acceleration and speed regulation.

---

9.7 Metals and Heavy Processing Equipment

Large processing machinery can benefit from adjustable-speed motor control.

Applications can include material handling, cooling systems, large pumps, large fans, process machinery, and other equipment requiring high-power motor regulation.

---

10. Main Product Advantages

10.1 980 A High-Current Capability

The 980 A rating is the primary advantage of this model.

It is designed for very large industrial motors and can accommodate a level of motor current that is far beyond ordinary compact variable-frequency drives.

---

10.2 High Horsepower Capability

The approximately 1,100 HP Low Duty rating makes the model appropriate for extremely large motor applications.

The 1,000 HP Normal Duty and 900 HP Heavy Duty ratings also provide useful capacity for applications with greater mechanical loading.

---

10.3 Adjustable Motor Speed

The drive provides variable-speed operation.

This can improve process flexibility because equipment can operate at the speed actually required instead of being restricted to fixed line-frequency operation.

---

10.4 Controlled Acceleration

Large motors can produce significant starting current and mechanical stress when connected directly to the electrical supply.

Variable-frequency starting allows the motor to accelerate in a controlled manner.

This can reduce mechanical shock and improve the overall starting behavior of large machines.

---

10.5 Process Optimization

Variable-speed control can be used to regulate process output.

For pumps and fans, this may provide a more efficient operating method than continuously operating the motor at maximum speed and controlling flow through mechanical restrictions.

---

10.6 Industrial Network Integration

Embedded EtherNet/IP provides a practical method for integrating the drive with an industrial control system.

This can simplify centralized monitoring and control.

---

10.7 Large Industrial Installation Architecture

The Frame 9 MCC-style configuration is well suited to large electrical rooms and centralized motor-control installations.

It provides a more organized architecture for very large drive equipment than attempting to use numerous smaller drive units.

---

11. Recommended Five Related Models in the Same Series

The following models are particularly relevant when comparing capacity, voltage, enclosure depth, or application requirements within the PowerFlex 755 range.

The first three are the most logical comparisons when the electrical system is based around 600 VAC.

The 690 VAC models are more appropriate when the plant electrical system and motor are designed for the higher voltage class.

---

12. Detailed Comparison of Related Models

The dimensions and weights of large cabinet configurations can change with the selected cabinet arrangement and factory options. The values above are therefore best used for preliminary selection and comparison rather than final mechanical design.

---

13. Five Popular Related Models From the Same Brand

For users who want to compare this high-power unit with other commonly used models from the same brand, the following five are useful reference points.

These models illustrate the broad capacity range available within the same industrial drive family.

The small models are intended for relatively modest motors, while the 980 A Frame 9 model is designed for extremely large industrial motor systems.

---

14. Small-to-Large Model Comparison

The large difference between the current ratings demonstrates why the 20G11BE980JN0NNNNN should not be treated as a normal machine-level inverter.

It is a large-scale industrial motor-control product requiring appropriate electrical infrastructure, mechanical installation, cooling, protection, and maintenance planning.

15. Application Matching Table

16. Installation Considerations

Because this is a large Frame 9 drive, installation requirements are significantly more demanding than those of compact variable-frequency drives.

The equipment requires adequate electrical-room space.

The approximate cabinet dimensions are in the 2.45 m height × 1.2 m width × 0.6 m depth class, which means that transportation routes, door openings, lifting equipment, and floor loading should be checked before installation.

The approximate equipment weight is in the 1,200–1,300 kg range, depending on the exact cabinet and configuration.

This means that the installation area should be evaluated for structural loading and suitable lifting arrangements.

---

17. Cooling Requirements

The 980 A power rating means that considerable heat can be generated during operation.

The forced-air cooling system therefore becomes an important part of the installation.

The electrical room should provide sufficient ventilation and should prevent hot exhaust air from being recirculated into the drive intake.

Filters, fans, airflow paths, and cooling components should be included in the maintenance program.

High ambient temperatures can reduce drive performance or require derating, so the actual installation environment should be considered during engineering.

---

18. Advantages in Energy Management

One of the most important practical advantages of variable-speed control is the ability to match motor speed to actual process demand.

For suitable centrifugal pump and fan systems, reducing motor speed can produce substantial reductions in energy consumption.

For example, when a pump does not need full flow, reducing speed can be more efficient than running the motor at full speed and using a valve to restrict flow.

Similarly, a large ventilation fan does not necessarily need maximum speed when the building or process requires only partial airflow.

The actual energy savings depend on the mechanical system, operating point, motor efficiency, process requirements, and operating schedule.

---

19. Maintenance Considerations

Large industrial drives should be included in a planned preventive-maintenance program.

Typical inspection items include:

For a high-current drive, preventive maintenance is particularly important because an unexpected failure can affect a very large production system.

Among these, the first three are the most useful when the plant electrical system is based on 600 VAC.

The 690 VAC models should only be considered when the motor and electrical distribution system are actually designed for the higher voltage class.

---

24. Final Assessment

The 20G11BE980JN0NNNNN is a high-capacity PowerFlex 755 AC drive intended for large industrial motors.

Its key specifications are a 600 VAC voltage class, 980 A current rating, approximately 1,100 HP Low Duty capacity, 1,000 HP Normal Duty capacity, and 900 HP Heavy Duty capacity.

The Frame 9, 600 mm-deep MCC-style configuration makes it a large cabinet-mounted product rather than a compact drive.

The combination of high current capacity, forced-air cooling, industrial communication, adjustable-speed control, controlled motor starting, and large motor capability makes it particularly suitable for major industrial installations.

The most closely related alternatives are the 20G11BE825JN0NNNNN, 20G11BE900JN0NNNNN, 20G11BE980AN0NNNNN, 20G11LE980JN0NNNNN, and 20G11JE980JN0NNNNN.

For an existing 600 VAC installation requiring approximately 980 A, the 20G11BE980JN0NNNNN remains a particularly strong configuration to evaluate.

For a lower motor-current requirement, the 825 A and 900 A versions may provide a more appropriately sized solution.

For 690 VAC systems, the corresponding 690 V configurations should be considered instead.

The most important selection principle is to match the drive to the actual motor full-load current, voltage, duty classification, torque requirement, acceleration profile, overload requirement, enclosure requirements, communication architecture, braking requirements, physical dimensions, cooling conditions, and installation environment rather than selecting solely by horsepower.

Note: Dimensions and weight for large Frame 9 equipment can vary with the exact cabinet arrangement and installed options. The values above are intended for technical comparison and preliminary planning; final mechanical installation should use the actual equipment configuration.
