20G11BE900JN0NNNNN — Detailed Product Information

1. Product Overview

The 20G11BE900JN0NNNNN is a high-power AC variable frequency drive designed for large industrial motor-control applications. It belongs to the PowerFlex 755 series and is positioned in the high-current, large-frame section of the product family.

The model is configured for a 600 VAC, three-phase input and provides a rated output current of 900 A. Its published capacity is 1,000 HP for Light Duty, 950 HP for Normal Duty, and 800 HP for Heavy Duty.

The unit uses a Frame 9 construction and a 600 mm deep MCC-style enclosure. It is an air-cooled, Type 1 / IP20 packaged AC drive with an AC input, precharge function, DC terminals, embedded EtherNet/IP, filtering, and a common-mode jumper installed.

The model is supplied in a blank / no-HIM configuration, meaning that a factory-mounted local HIM is not included in this particular catalog configuration. This makes the model well suited to installations where operation and monitoring are primarily handled through a central control system or an external operator interface.

Because of its 900 A output rating, this is not a compact machine-level inverter. It is a large industrial drive intended for substantial motors and equipment such as large pumps, fans, conveyors, compressors, crushers, material-handling systems, and other high-power machinery.

4. Dimension and Weight Information

The physical characteristics of this model are particularly important because it belongs to the very-large Frame 9 class.

Mechanical Parameter	Specification
Frame	Frame 9
Cabinet Style	MCC Style
Enclosure Depth	600 mm
Width	Configuration dependent
Height	Configuration dependent
Overall H × W × D	Must be confirmed from the exact mechanical drawing
Approximate Equipment Weight	1,270 kg class

The 600 mm figure represents the specified enclosure depth. It should not be interpreted as the complete physical size of the drive.

For transportation, cabinet layout, foundation design, floor-loading calculations, lifting operations, and maintenance planning, the complete height and width should be taken from the mechanical drawing corresponding to the exact packaged configuration.

The approximate 1,270 kg weight places the unit firmly in the heavy industrial equipment category. A drive of this size requires suitable lifting equipment and a properly designed supporting structure.

For a real installation, the equipment nameplate and final mechanical documentation should be used for the final shipping weight, installed weight, center of gravity, lifting arrangement, and foundation calculations.

---

5. Electrical Specifications Explained

5.1 600 VAC Input

The drive is designed for the 600 VAC three-phase class.

This voltage class is commonly associated with large industrial electrical systems.

Using a higher system voltage for high-power equipment helps keep current levels within a manageable range on the incoming electrical distribution side.

---

5.2 900 A Output

The 900 A output rating is the defining characteristic of this model.

It places the drive among the very high-current configurations of the PowerFlex 755 series.

A 900 A drive is intended for large motors where the current demand is far beyond the range of compact industrial drives.

---

5.3 Three Duty Ratings

The model has three principal horsepower ratings.

Duty Type	Rating	Approx. kW
Light Duty	1,000 HP	746 kW
Normal Duty	950 HP	708 kW
Heavy Duty	800 HP	597 kW

These ratings should not be treated as interchangeable.

The actual motor application determines which duty rating is appropriate.

For a relatively stable load, the normal-duty rating may be the most relevant reference.

For equipment with high torque demand, repeated overloads, or severe acceleration requirements, the heavy-duty rating is more important.

---

6. Product Introduction

The 20G11BE900JN0NNNNN is designed to provide controlled variable-speed operation for very large AC motors.

In a conventional fixed-speed motor installation, the motor generally operates at a speed determined by the power-system frequency and motor design.

A variable frequency drive changes the electrical frequency supplied to the motor, allowing the motor speed to be adjusted.

This provides a major advantage in industrial processes where equipment demand changes over time.

A pump does not necessarily need maximum flow continuously.

A fan does not necessarily need maximum airflow continuously.

A conveyor may need different speeds for different production conditions.

A compressor may need to follow changing process demand.

A process machine may require controlled acceleration, controlled deceleration, and different operating speeds during different stages of production.

The drive provides the electrical control needed to achieve these operating conditions.

At this power level, the drive is also an important part of the plant’s electrical infrastructure. Installation is therefore not simply a matter of mounting the inverter and connecting a motor. Power distribution, cooling, grounding, cable routing, EMC, mechanical support, maintenance access, and control-system integration all need to be considered.

---

7. Main Functions

7.1 Variable-Speed Operation

The primary function is to regulate motor speed.

The drive can adjust output frequency and voltage to provide the required motor operating point.

This allows the machine to operate closer to actual process requirements instead of running continuously at maximum speed.

---

7.2 Controlled Acceleration

Large motors can create significant mechanical stress during startup.

Controlled acceleration allows the motor to increase speed gradually.

This can reduce stress on:

• Gearboxes
• Couplings
• Shafts
• Belts
• Chains
• Conveyor structures
• Pump assemblies
• Fan assemblies
• Compressor systems

This is especially useful for machines with large rotating masses.

---

7.3 Controlled Deceleration

The drive can also control motor deceleration.

The stopping behavior depends on the load inertia, programmed parameters, motor characteristics, and braking requirements.

This specific configuration has no dynamic braking.

Therefore, applications requiring rapid deceleration of very high-inertia loads should be evaluated carefully before final drive selection.

---

7.4 Industrial Network Integration

The embedded EtherNet/IP capability allows the drive to communicate with a larger industrial automation system.

Typical information exchanged with the control system can include:

• Start and stop commands
• Speed reference
• Actual speed
• Current
• Drive status
• Fault information
• Alarm information
• Operating conditions
• Diagnostic information

This can make the drive easier to integrate into centralized production-control systems.

---

8. Product Applications

8.1 Large Pump Systems

Large pumps are among the most suitable applications for a high-power variable frequency drive.

Typical applications include:

• Water circulation
• Wastewater treatment
• Cooling systems
• Industrial process water
• Chemical process systems
• Mining dewatering
• Large irrigation systems
• Process-fluid transfer

The ability to reduce pump speed when full flow is unnecessary can provide significant energy-saving potential.

---

8.2 Large Fans and Blowers

Industrial fans can consume substantial electrical power.

Variable-speed operation allows airflow to be adjusted according to actual process demand.

Typical applications include:

• Industrial ventilation
• Furnace systems
• Exhaust systems
• Cooling systems
• Dust collection
• Forced-draft fans
• Induced-draft fans
• Large process blowers

The 900 A current class makes the model appropriate for very large fan motors.

---

Heavy conveyors can require motors with several hundred horsepower or more.

Applications include:

• Mining conveyors
• Bulk-material conveyors
• Cement conveyors
• Aggregate handling
• Port equipment
• Steel-material handling

The drive can provide controlled acceleration, reducing the mechanical shock associated with starting a heavily loaded conveyor.

---

8.4 Compressors

Large compressors can also use high-power variable-speed drives.

Variable-speed control allows compressor output to follow process requirements more closely.

This can be useful when demand changes significantly during production.

Compressor applications should be evaluated according to the actual compressor torque curve, motor current, acceleration requirements, and overload characteristics.

---

8.5 Crushers

Crushers can impose substantial torque demands on their motors.

The ability to control acceleration and motor operation can be useful when starting heavy mechanical loads.

For crusher applications, the heavy-duty rating should receive particular attention.

---

8.6 Mills and Grinding Equipment

Large mills and grinding machines may require high motor torque and significant continuous power.

The 900 A drive class provides sufficient capacity for many large motor installations.

The final selection should be based on the actual motor nameplate current and the process load profile.

---

8.7 Mining Equipment

The model is particularly relevant to mining applications because mining equipment frequently uses very large motors.

Typical equipment includes:

• Ore conveyors
• Crushers
• Large pumps
• Ventilation fans
• Processing machinery
• Material-handling equipment

The combination of high current, industrial communication, variable-speed control, and large-frame construction makes the drive suitable for these demanding environments.

---

9. Product Advantages

9.1 Very High Current Capacity

The 900 A rating is the primary advantage.

This provides substantial capacity for large industrial motors.

Compared with lower-current drives in the same family, the 900 A configuration can accommodate significantly larger motors and higher process loads.

---

9.2 Up to 1,000 HP Light-Duty Capacity

The 1,000 HP light-duty rating places the drive in the very-high-power industrial category.

It is suitable for applications where large motors need controlled operation without using multiple smaller drives for the same motor.

---

9.3 950 HP Normal-Duty Rating

The 950 HP normal-duty rating is particularly relevant to large continuous-process equipment.

For applications with relatively stable loading, this rating provides a useful reference for motor selection.

---

9.4 800 HP Heavy-Duty Rating

The 800 HP heavy-duty rating is important for applications where higher overload capability is needed.

Examples can include:

• Crushers
• Heavy conveyors
• Mixers
• Mills
• High-torque process machines

The actual motor current and overload requirements should always be checked.

---

9.5 Embedded EtherNet/IP

Embedded network communication is a major advantage in modern industrial automation.

It allows the drive to become part of the plant’s control architecture rather than operating as an isolated device.

---

9.6 Forced-Air Cooling

High-power electrical equipment generates substantial heat.

The forced-air cooling arrangement helps remove heat from the drive’s power electronics.

Proper airflow is essential to maintaining reliable operation.

---

9.7 Filtered Configuration

The filtered configuration helps address electromagnetic compatibility requirements.

This is valuable in industrial plants where drives operate alongside instrumentation, controllers, sensors, communication equipment, and other electronic systems.

---

9.8 MCC-Style Mechanical Configuration

The 600 mm deep MCC-style construction makes the drive suitable for larger industrial electrical rooms and structured motor-control installations.

This is particularly useful in facilities containing multiple high-power drives.

---

---

14. Energy-Saving Advantages

The 20G11BE900JN0NNNNN can provide substantial energy-saving potential when applied to suitable variable-torque loads.

This is particularly relevant to pumps and fans.

A pump or fan running continuously at maximum speed can consume far more power than necessary when process demand is low.

Reducing motor speed allows the equipment to operate closer to actual requirements.

For very large motors, the difference can be significant.

For example, a facility operating a large pump for many hours per year may be able to reduce electricity consumption by controlling speed instead of maintaining full-speed operation and regulating the process primarily through valves or dampers.

The actual energy savings depend on:

• Motor efficiency
• Pump or fan characteristics
• Required process output
• Annual operating hours
• Speed range
• Mechanical efficiency
• Control strategy
• Process demand

The drive itself does not guarantee a specific energy saving. The saving comes from matching motor operation more closely to the actual process requirement.

---

15. Mechanical Advantages

Variable-speed operation can also provide mechanical benefits.

A large motor connected directly to a mechanical load can create a sudden torque change during starting.

The drive can gradually increase torque and speed.

This can reduce stress on mechanical components such as:

• Couplings
• Gearboxes
• Shafts
• Conveyor belts
• Chains
• Pump impellers
• Fan assemblies
• Compressor components
• Process-machine transmission systems

For equipment with high inertia, controlled acceleration can be particularly valuable.

---

16. Control-System Advantages

The embedded EtherNet/IP capability makes the drive suitable for centralized industrial control.

Instead of treating the drive as a separate electrical device, it can become part of the wider machine-control system.

Typical control functions can include:

• Remote start and stop
• Speed reference
• Operating-state monitoring
• Current monitoring
• Fault monitoring
• Alarm management
• Diagnostic information
• Parameter management

This can reduce manual intervention and make large industrial equipment easier to monitor from a control room.

---

17. Installation Considerations

The physical characteristics of the 20G11BE900JN0NNNNN should be considered early in a project.

Installation Factor	Consideration
Floor Loading	Equipment is approximately 1,270 kg class
Cabinet Depth	600 mm
Cabinet Height	Configuration dependent
Cabinet Width	Configuration dependent
Lifting	Heavy industrial lifting equipment required
Transportation	Route and doorway dimensions must be checked
Ventilation	Forced-air cooling requires adequate airflow
Heat Dissipation	Electrical-room HVAC should account for drive losses
Cable Routing	High-current power cables require careful planning
Grounding	Proper protective grounding is essential
EMC	Motor and control cables should be routed appropriately
Service Access	Adequate maintenance clearance is required
Anchoring	Equipment must be securely supported
Environment	Avoid excessive dust, moisture and corrosive contamination

The large weight means that floor loading should not be treated as a minor consideration.

The supporting structure should be evaluated before the equipment arrives at the installation site.

---

18. Cooling and Thermal Management

The drive is air cooled.

This is important because a high-power drive can generate substantial heat during normal operation.

The cooling system needs sufficient clean airflow.

Blocked ventilation paths can cause internal temperature to increase.

High ambient temperatures can also reduce the available operating margin.

The electrical room should therefore be designed with suitable ventilation and heat removal.

Where several large drives are installed in the same room, their combined heat output can become a significant part of the building’s HVAC calculation.

---

19. Maintenance Considerations

Cooling Fans

Cooling fans should be inspected regularly for abnormal noise, vibration, reduced airflow, and signs of wear.

Because the drive operates at very high power, cooling performance is directly related to long-term reliability.

Electrical Connections

High-current connections should be maintained according to the applicable maintenance schedule.

Poor connections can create localized heating and increase the risk of equipment damage.

Airflow Paths

Ventilation paths should be kept clean.

Dust accumulation can reduce cooling efficiency.

Fault History

Drive alarms and faults should be analyzed rather than simply reset repeatedly.

Repeated over-current, over-temperature, DC-bus, or communication problems can indicate an underlying mechanical, electrical, or control-system issue.

---

20. Selection Guide for the 900 A Model

The 20G11BE900JN0NNNNN should generally be considered when the following conditions apply:

Selection Factor	Suitable Condition
Motor Voltage	600 VAC class
Motor Size	Very large industrial motor
Motor Current	Within the 900 A drive capability
Application	Industrial variable-speed motor control
Load	Pump, fan, conveyor, compressor, crusher, mill or similar
Duty	Light, normal or heavy according to actual rating
Communication	EtherNet/IP required or beneficial
Installation	Large MCC-style electrical system
Cooling	Forced-air installation available
Cabinet	Space available for Frame 9 equipment
Weight	Supporting structure can accommodate approximately 1,270 kg class equipment

---

21. When to Choose a Smaller Model

A 900 A drive should not automatically be selected simply because the motor horsepower is large.

If the actual motor current is significantly below the 900 A range, a smaller PowerFlex 755 model may be more appropriate.

The 760 A and 825 A configurations can provide substantial capacity while reducing the required drive rating.

Choosing a drive closer to the actual motor requirement can sometimes reduce equipment cost and simplify the overall installation.

However, the final decision should consider overload capability, ambient conditions, acceleration requirements, and the actual load profile.

---

22. When to Choose a Larger Model

The 980 A configuration becomes worth considering when the motor current approaches the limits of the 900 A model or when additional capacity is required for the application.

This may occur with:

• High-inertia equipment
• Severe overload conditions
• Heavy material handling
• Large crushers
• High-torque process machinery
• Difficult acceleration requirements

The heavy-duty rating should be checked carefully before making the final decision.

---

24. Final Product Assessment

The 20G11BE900JN0NNNNN is a high-capacity industrial AC variable frequency drive in the PowerFlex 755 series.

Its defining characteristics are the 600 VAC three-phase electrical class, 900 A output current, 1,000 HP light-duty rating, 950 HP normal-duty rating, 800 HP heavy-duty rating, Frame 9 construction, 600 mm deep MCC-style enclosure, Type 1 / IP20 protection, forced-air cooling, embedded EtherNet/IP, filtered configuration, precharge input, DC terminals, and blank/no-HIM configuration.

The model is particularly well suited to very large industrial equipment.

Its most natural applications include large pumps, fans, conveyors, compressors, crushers, mills, mining equipment, material-handling systems, and heavy process machinery.

The greatest technical advantage is the combination of very high current capacity with flexible variable-speed motor control.

For pumps and fans, the main benefit can be better process matching and energy management.

For conveyors and heavy material-handling equipment, controlled acceleration can reduce mechanical stress.

For compressors and process machines, variable speed can help match equipment output to actual process requirements.

For large industrial automation systems, embedded EtherNet/IP provides a convenient method of connecting the drive to the plant control network.

The physical characteristics should also be taken seriously. The 600 mm enclosure depth and approximately 1,270 kg class weight place this equipment in a completely different installation category from compact VFDs. Floor loading, transportation, lifting, ventilation, cable routing, grounding, EMC, and maintenance clearance should all be considered during engineering.

For a motor requirement below the 900 A range, the 760 A or 825 A versions may be more economical choices.

For an application that requires additional current capacity, the 980 A version is a logical higher-capacity comparison.

For existing installations, the complete catalog number should always be matched before replacement because differences in operator interface, filtering, enclosure, braking, communication, and other option codes can affect compatibility.

In practical terms, the 20G11BE900JN0NNNNN is best characterized as a very-high-power, large-frame industrial variable frequency drive intended for major motor-driven equipment, particularly where high current, controlled acceleration, variable speed, network integration, and reliable industrial operation are required.
