Allen-Bradley 20G1F3E595LNDNNNNN PowerFlex 755 AC Drive

1. Product Overview

The 20G1F3E595LNDNNNNN is a high-power industrial AC variable frequency drive from the Allen-Bradley PowerFlex 755 series.

It is designed for large three-phase AC motor applications where high current capacity, adjustable motor speed, controlled acceleration and deceleration, and flexible industrial motor control are required.

This model is part of the large-frame PowerFlex 755 product family and is associated with a 600 V AC class and approximately 596 A rated current.

Unlike compact variable frequency drives intended for small machines, this type of drive is designed for large industrial equipment. It can be applied to large pumps, fans, conveyors, compressors, processing machinery, material-handling systems, and other heavy-duty motor-driven equipment.

The model is an air-cooled AC packaged drive configuration. Its physical size is considerably larger than compact panel-mounted drives because the drive must handle a very high electrical current and dissipate a substantial amount of heat during operation.

The complete catalog number is important when identifying this product because the letters and numbers at the end of the catalog number represent configuration information. A replacement should therefore be selected by comparing the complete catalog number, electrical requirements, enclosure arrangement, options, and application requirements rather than comparing only voltage and current.

The product belongs to the PowerFlex 755 family and is commonly associated with large industrial motor-control systems.

4. Product Dimensions and Weight

Because the 20G1F3E595LNDNNNNN is a large packaged drive rather than a small standalone inverter module, its physical dimensions need to be considered at the cabinet level.

A practical reference for a large-frame installation is approximately:

Dimension / Physical Characteristic	Approximate Value
Height	≈ 2450 mm
Width	≈ 1200 mm
Depth	≈ 600–800 mm
Weight	≈ 1246 kg
Height in inches	≈ 96.5 in
Width in inches	≈ 47.2 in
Depth in inches	≈ 23.6–31.5 in
Weight in pounds	≈ 2747 lb

The approximately 1246 kg figure should be treated as a reference value for the large-frame cabinet arrangement. It should not automatically be used as the shipping weight for every possible configuration.

Additional cabinets, disconnect equipment, filtering equipment, input/output components, enclosure options and other accessories can increase both the overall dimensions and the total weight.

For installation planning, it is therefore advisable to allow additional clearance around the cabinet and to verify the actual nameplate and mechanical drawing for the specific unit being installed.

---

5. Product Series — PowerFlex 755

The 20G1F3E595LNDNNNNN belongs to the PowerFlex 755 series.

The PowerFlex 755 family is intended for demanding industrial motor-control applications. It covers a wide range of drive sizes and current ratings, allowing the same general drive platform to be used from relatively moderate industrial applications through very large motor installations.

The 755 series is particularly suitable where a basic fixed-speed starter is insufficient and the motor needs controlled speed, torque, acceleration, deceleration or process-related operation.

The high-current configurations are physically large because they are intended to control large motors and industrial loads.

The series can be found in applications involving:

• Large pumps
• Industrial fans
• Heavy conveyors
• Compressors
• Mixers
• Crushers
• Mills
• Material-handling equipment
• Processing machinery
• Large production systems

The series is also suitable for applications where integration with an industrial control system is required.

---

6. Understanding the Model Number

The catalog number 20G1F3E595LNDNNNNN contains multiple configuration characters.

The first portion identifies the PowerFlex 755 product family.

The remaining characters identify characteristics such as the drive configuration, electrical arrangement, enclosure or packaging arrangement, and other factory-selected options.

For this reason, two PowerFlex 755 drives can have very similar electrical ratings but still have different catalog numbers and different physical or functional configurations.

This is particularly important when replacing an existing large drive.

A replacement should be checked against:

1. Input voltage.
2. Motor voltage.
3. Motor full-load current.
4. Normal-duty rating.
5. Heavy-duty rating.
6. Overload requirements.
7. Enclosure type.
8. Cooling arrangement.
9. Input configuration.
10. Output configuration.
11. Feedback requirements.
12. Braking requirements.
13. Communication requirements.
14. Harmonic requirements.
15. Cabinet dimensions.
16. Existing control-system architecture.
17. Available installation space.
18. Cable entry arrangement.
19. Environmental conditions.
20. Required maintenance access.

7. Product Introduction

The 20G1F3E595LNDNNNNN is intended for applications where the motor load is large enough that a conventional small variable-frequency drive is not suitable.

The 596 A current rating places this product in the high-power industrial category.

In a typical installation, the drive receives three-phase AC electrical power from the plant distribution system and converts that electrical power into controlled variable-frequency output power for the motor.

By changing the output frequency and voltage according to the selected control strategy, the drive can control motor speed and operating torque.

This provides considerably more control than a simple motor starter.

For example, a conveyor can gradually accelerate instead of starting suddenly. A pump can operate at a lower speed when full flow is not required. A fan can adjust its speed according to ventilation requirements. A compressor can be controlled according to the process demand.

The drive therefore acts as an important interface between the plant electrical system and the mechanical equipment.

---

8. How the Product Works

A variable-frequency drive essentially controls the electrical energy supplied to the motor.

The incoming AC power is processed by the drive’s power-conversion section.

The drive then generates a controlled output waveform that allows the connected AC motor to operate at the required speed and torque.

For a large industrial drive such as the 20G1F3E595LNDNNNNN, the power section must handle a very substantial current.

This explains the large physical construction, large cooling system, substantial semiconductor power section, large bus structure, and heavy cabinet arrangement.

The drive can also provide controlled acceleration and deceleration.

Instead of applying full electrical power to the motor immediately, the motor can be brought from standstill toward operating speed according to a programmed acceleration profile.

The same principle can be used during stopping.

This can reduce sudden mechanical loading on shafts, couplings, gearboxes, belts, pumps, fans and other connected equipment.

---

9. Main Product Applications

9.1 Large Pump Systems

Large pumps are one of the most suitable applications for high-power variable-frequency drives.

A pump does not necessarily need to operate at maximum speed continuously.

With adjustable-speed operation, the motor can operate closer to the actual process requirement.

Typical applications include:

• Water treatment
• Industrial water circulation
• Cooling-water systems
• Process water
• Chemical processing
• Wastewater systems
• Irrigation
• Large fluid-transfer systems
• Manufacturing processes

The ability to change motor speed can also make process control easier because the pump output can be adjusted without relying entirely on mechanical throttling.

---

10. Fan and Blower Applications

Large fans and blowers can require substantial motor power, especially in manufacturing plants and heavy industrial facilities.

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

Applications include:

• Industrial ventilation
• Furnace ventilation
• Process exhaust
• Dust collection
• Large HVAC systems
• Mining ventilation
• Industrial cooling
• Air-handling equipment

Variable-speed operation can be particularly useful when the required airflow changes throughout the production process.

---

11. Conveyor Applications

Heavy conveyors can experience high starting torque and large changes in mechanical load.

The drive can provide controlled acceleration and deceleration, helping the conveyor reach operating speed in a controlled manner.

Potential applications include:

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

The ability to control motor speed can also be useful when different sections of a production line need to operate at different rates.

---

12. Compressor Applications

Large compressors can require considerable motor current, particularly during acceleration and under heavy process conditions.

A high-power drive can provide controlled motor operation and allow the compressor system to respond to changing process requirements.

Possible applications include:

• Industrial air compressors
• Process compressors
• Gas-processing equipment
• Manufacturing systems
• Refrigeration-related industrial equipment
• Chemical-processing machinery

The final drive selection should always be based on the compressor manufacturer’s motor requirements and the actual load profile.

---

13. Crusher and Mill Applications

Heavy processing equipment often requires high starting torque and substantial continuous motor current.

The PowerFlex 755 high-current platform can be considered for equipment such as:

• Crushers
• Mills
• Mixers
• Grinding equipment
• Material processors
• Heavy-duty agitators
• Industrial processing machines

These applications require careful attention to overload capacity, acceleration time, torque requirements and mechanical inertia.

---

14. Mining Applications

The high current capability of this drive makes it suitable for consideration in large mining and mineral-processing installations.

Potential applications include:

• Ore conveyors
• Crushers
• Large fans
• Pumping systems
• Processing equipment
• Material-handling machinery
• Ventilation systems
• Heavy-duty process machinery

Mining installations often require robust electrical equipment because the motor loads can change rapidly and the operating environment can be demanding.

---

15. Manufacturing Applications

The product can also be used in large manufacturing systems where motors need to operate at different speeds.

Examples include:

• Production lines
• Material-handling systems
• Large mixers
• Processing machines
• Extrusion systems
• Industrial winding equipment
• Large machine tools
• Heavy production equipment

The exact suitability depends on the motor and mechanical load characteristics.

---

16. Main Product Advantages

16.1 High Current Capacity

The most important characteristic of this model is its approximately 596 A current rating.

This gives the drive the capacity to serve large industrial motors that cannot be handled by smaller variable-frequency drives.

---

16.2 Large Motor Compatibility

The PowerFlex 755 platform is designed around industrial motor applications.

The large-frame configurations provide a practical solution for large motor systems where compact drives are not sufficient.

---

16.3 Adjustable Motor Speed

The drive allows the motor speed to be controlled rather than simply switching the motor between ON and OFF states.

This is particularly useful for pumps, fans, conveyors and process machinery.

---

16.4 Controlled Acceleration

Large motors can create substantial mechanical stress when started abruptly.

The drive can gradually accelerate the motor according to the configured acceleration profile.

This can help reduce mechanical shock.

---

16.5 Controlled Deceleration

The same principle applies when stopping the motor.

Controlled deceleration can help reduce sudden loading on mechanical components and can provide smoother machine operation.

---

16.6 Flexible Industrial Control

The PowerFlex 755 family is intended for applications where more advanced motor-control functions are required.

Depending on configuration, the system can support different feedback, communication, braking and control arrangements.

---

16.7 Suitable for Centralized Industrial Systems

The drive can form part of a larger automation architecture.

For example, a PLC or supervisory control system can command the drive according to production requirements.

The drive then handles the motor-control portion of the system.

---

16.8 Heavy-Duty Industrial Construction

The physical construction is designed around large industrial applications.

The large cabinet, cooling arrangement and high-current power section are appropriate for applications where electrical power levels are significantly higher than those encountered in small machines.

---

17. Installation Considerations

The size and weight of this product should not be underestimated.

A large-frame cabinet weighing approximately 1246 kg requires proper transportation, positioning and lifting arrangements.

The installation location should have sufficient structural capacity to support the equipment.

Adequate access should also be provided for:

• Power cables
• Control cables
• Ventilation
• Maintenance
• Inspection
• Component replacement
• Electrical isolation
• Service personnel

The installation area should not be selected solely according to cabinet footprint.

The additional space required for opening doors, servicing components and routing cables should also be considered.

---

18. Environmental Considerations

The drive should be installed in an environment appropriate for industrial electrical equipment.

Important considerations include:

• Ambient temperature
• Humidity
• Dust
• Corrosive gases
• Vibration
• Altitude
• Airflow
• Heat accumulation
• Electrical contamination

Air-cooled equipment requires adequate ventilation.

If the cabinet is installed in a poorly ventilated room, the internal temperature can rise and reduce the available thermal capacity of the drive.

For large-power equipment, thermal management is therefore an important part of system design.

---

19. Maintenance Considerations

Large variable-frequency drives should be incorporated into a planned maintenance program.

Maintenance can include:

• Visual inspection
• Cooling-system inspection
• Fan inspection
• Cabinet cleanliness
• Cable connection inspection
• Terminal inspection
• Electrical connection checks
• Alarm history review
• Drive parameter backup
• Control-system verification
• Inspection of ventilation paths

The actual maintenance interval depends on operating conditions.

A dusty industrial environment may require considerably more frequent cleaning than a clean electrical room.

The following models are useful comparison models within the same PowerFlex 755 high-power family.

Model	Series	Voltage Class	Current Class	Cooling	Application	Approx. Size	Approx. Weight
20G1F3E545LNDNNNNN	PowerFlex 755	600 V	545 A class	Air cooled	Large pumps, fans, conveyors	Large-frame cabinet	Approx. 1200+ kg class
20G1F3E595LNDNNNNN	PowerFlex 755	600 V	596 A	Air cooled	Large industrial motors	Approx. 2450 × 1200 × 600–800 mm	Approx. 1246 kg
20G1F3E690LNDNNNNN	PowerFlex 755	600 V	690 A class	Air cooled	Heavy industrial motors	Large-frame cabinet	Configuration dependent
20G1F3E760LNDNNNNN	PowerFlex 755	600 V	760 A class	Air cooled	Heavy-duty machinery	Large-frame cabinet	Configuration dependent
20G1F3E825LNDNNNNN	PowerFlex 755	600 V	825 A class	Air cooled	Very large motor systems	Large-frame cabinet	Configuration dependent

These models are useful when comparing different current capacities within the same general product family.

The 20G1F3E595LNDNNNNN is positioned between the lower-current and higher-current configurations.

---

21. Same-Series Model Comparison

Model	Rated Current Class	Voltage Class	Relative Capacity	Typical Use
20G1F3E545LNDNNNNN	545 A	600 V	Lower than target model	Large pumps, fans and conveyors
20G1F3E595LNDNNNNN	596 A	600 V	Target configuration	Large industrial motor systems
20G1F3E690LNDNNNNN	690 A	600 V	Higher	Larger motors and heavier loads

20G1F3E825LNDNNNNN	825 A	600 V	Higher	Very large industrial applications

When choosing between these models, the current rating should not be the only consideration.

The motor nameplate current, overload requirement, duty cycle, ambient temperature, motor type, acceleration requirement and actual load characteristics should all be considered.

---

22. Five Related Models from the Same Brand

The following models represent other commonly encountered Allen-Bradley drive families and provide useful alternatives for different motor sizes and applications.

Model	Series	Voltage Class	Approx. Current / Capacity	Cooling	Approx. Dimensions	Approx. Weight	Typical Application
25B-D017N104	PowerFlex 525	480 V class	17 A class	Air cooled	Compact drive enclosure	Approx. 5–10 kg class	Small machines, pumps, fans
22F-D024N103	PowerFlex 4M	480 V class	24 A class	Air cooled	Compact	Approx. 3–6 kg class	Small machinery and conveyors
20F1ANC156AA0NNNNN	PowerFlex 753	480 V class	High-power class	Air cooled	Large industrial configuration	Configuration dependent	Industrial machinery
20G1F3E595LNDNNNNN	PowerFlex 755	600 V class	596 A	Air cooled	Approx. 2450 × 1200 × 600–800 mm	Approx. 1246 kg	Large industrial motors
20G1F3E980LNDNNNNN	PowerFlex 755	600 V class	980 A class	Air cooled	Very large-frame configuration	Configuration dependent	Extremely large motor systems

These models cover substantially different application ranges.

The PowerFlex 4M and PowerFlex 525 families are intended for considerably smaller applications, while the PowerFlex 753 and PowerFlex 755 families are used for more demanding industrial installations.

The 20G1F3E595LNDNNNNN is therefore positioned at the high-power end of the range.

---

23. Comparison Between Small and Large Drives

A small drive such as a compact PowerFlex 525 may weigh only a few kilograms and can normally be mounted directly inside a machine control cabinet.

The 20G1F3E595LNDNNNNN is completely different in physical scale.

Its high current rating requires a substantially larger power section, cooling system and cabinet arrangement.

This difference affects almost every part of the installation.

A small drive may require only simple cabinet mounting.

A large drive requires:

• Floor loading analysis
• Transportation planning
• Lifting equipment
• Large power cables
• Proper ventilation
• Maintenance clearance
• Electrical isolation
• Heat management
• Larger control panels
• More substantial grounding arrangements

This is why the target model should be regarded as a major industrial electrical component rather than simply a larger version of a compact VFD.

---

24. Typical Motor-Control Functions

Depending on the exact configuration and control architecture, the PowerFlex 755 platform can be used for functions such as:

• Motor speed control
• Motor torque control
• Controlled acceleration
• Controlled deceleration
• Start/stop control
• Direction control
• Process-speed regulation
• Load-dependent speed control
• Closed-loop motor control
• Feedback-based control
• Industrial network integration
• Drive diagnostics
• Fault monitoring
• Parameter management

These functions allow the drive to become part of a complete machine-control system rather than operating as an isolated motor starter.

---

25. Advantages for Pump Applications

For a pump system, one of the major benefits is the ability to change motor speed according to the actual process requirement.

For example, a system that requires full pump output during peak demand may need considerably less output during low-demand periods.

Instead of operating the motor continuously at maximum speed, the drive can provide variable-speed operation.

This can improve process flexibility and may reduce unnecessary mechanical loading.

---

26. Advantages for Conveyor Applications

A conveyor can benefit from controlled acceleration because a large conveyor belt and its material load can have considerable inertia.

Starting the motor too aggressively can cause:

• Belt shock
• Mechanical stress
• Product movement
• Coupling stress
• Gearbox loading
• Excessive starting current

A variable-frequency drive can provide a controlled acceleration profile.

This is one reason high-power drives are frequently considered for heavy material-handling systems.

---

27. Advantages for Fan Applications

Fan speed can often be adjusted according to the required airflow.

When full airflow is unnecessary, the motor does not necessarily need to operate at maximum speed.

The drive can therefore become an important part of the overall airflow-control strategy.

This is particularly useful in:

• Ventilation
• Dust extraction
• Furnace systems
• Industrial cooling
• Process air systems

---

28. Advantages for Process Machinery

Industrial processing equipment often operates under changing load conditions.

The drive can provide controlled motor operation throughout the production cycle.

This can make it easier to coordinate motor speed with:

• Production rate
• Material flow
• Pressure
• Temperature
• Machine sequence
• Upstream equipment
• Downstream equipment

As a result, the drive can contribute to both motor control and overall process control.

---

29. Important Selection Information

This information is more important than simply matching the catalog number to another 596 A drive.

---

30. Replacement Considerations

The model 20G1F3E595LNDNNNNN is an older PowerFlex 755 catalog configuration.

For an existing machine, the replacement process should begin by identifying the exact existing drive configuration.

The nameplate should be checked carefully.

The following information should be recorded:

• Complete catalog number
• Series
• Firmware
• Input voltage
• Output voltage
• Current rating
• Enclosure type
• Installed options
• Communication modules
• Feedback devices
• Braking equipment
• External reactors
• Filters
• Cabinet configuration

A replacement with the same current rating is not necessarily electrically or mechanically identical.

For this reason, the complete configuration should be matched before the replacement is ordered.

34. Final Product Assessment

The 20G1F3E595LNDNNNNN is a high-capacity industrial variable-frequency drive intended for large motor applications.

Its 596 A, 600 V AC-class configuration places it firmly in the high-power industrial category.

The main reason to choose a drive of this size is the electrical and mechanical requirements of the motor system. It is not intended for small machines or simple low-power motor applications.

The product is particularly appropriate for applications where motor speed needs to be controlled accurately and where the motor has a substantial power requirement.

Typical applications include large pumps, industrial fans, heavy conveyors, compressors, crushers, mills, mixers, process equipment and large material-handling machinery.

Another important feature is controlled acceleration and deceleration. This can be valuable for large mechanical systems because the motor and driven equipment may have significant inertia.

The physical size of the equipment is also an important consideration. A large-frame cabinet can be approximately 2450 mm high, approximately 1200 mm wide and approximately 600–800 mm deep, with a reference weight around 1246 kg.

Therefore, installation planning must include structural loading, transportation, lifting, ventilation, cable routing and maintenance access.

For replacement applications, the complete catalog number should always be compared. The 596 A rating alone is not enough to guarantee that another PowerFlex 755 configuration is a direct mechanical and electrical replacement.

Overall, the 20G1F3E595LNDNNNNN can be described as a large-frame, air-cooled, 600 V-class, 596 A PowerFlex 755 industrial AC drive designed for high-power three-phase motor control.

Its strongest application area is large industrial equipment where adjustable speed, controlled acceleration, controlled deceleration and high motor current capacity are required.
