1. Product Identification

---

2. Product Introduction

The 20G11LE595AN2NNNNN is a large-capacity variable-frequency AC drive designed to control the speed and torque of industrial AC motors.

Its 595 A output capability places it in the high-power range of the PowerFlex 755 family.

Unlike a conventional motor starter, which generally starts a motor at essentially full line frequency, a variable-frequency drive can control the electrical frequency and voltage delivered to the motor.

This allows the motor to accelerate gradually, operate at different speeds and decelerate in a controlled manner.

For large industrial machinery, this type of control can provide significant operational advantages.

A pump, for example, may not need to operate at full speed continuously. A large conveyor may require a slow starting speed before reaching normal production speed. A fan may need to change speed according to ventilation requirements.

The 20G11LE595AN2NNNNN is intended for precisely these types of applications.

---

makes it suitable for large production machinery and process equipment.

---

4. Main Technical Parameters

---

5. Electrical Characteristics

The most important electrical characteristic of this model is its 595 A output current rating.

This makes it suitable for large AC motors and high-power industrial machinery.

The drive is designed for a 600 VAC, three-phase electrical system.

The motor and electrical supply should be checked carefully before installation.

---

6. Duty Ratings

The 595 A configuration has different motor horsepower ratings depending on the duty requirement.

This distinction is important when selecting the drive.

A motor operating a centrifugal fan may have a very different electrical load profile from a conveyor carrying heavy material.

The drive should therefore be selected based on the actual load characteristics rather than simply choosing a model according to the motor’s horsepower.

---

7. Light-Duty Applications

The light-duty rating is approximately 700 HP.

Light-duty applications generally have comparatively predictable loading and lower overload requirements.

Typical applications include:

• Large centrifugal fans
• Large centrifugal pumps
• Ventilation systems
• Cooling systems
• Certain process pumps
• Air-handling equipment

The actual motor current should still be checked before selection.

---

8. Normal-Duty Applications

The normal-duty rating is approximately 600 HP.

This rating is suitable for many conventional industrial motor applications.

Typical examples include:

• Industrial pumps
• Large fans
• Blowers
• Conveyors
• Process machinery
• Material-handling systems

The motor’s continuous current and operating cycle should be compared with the drive rating.

---

9. Heavy-Duty Applications

The heavy-duty rating is approximately 500 HP.

Heavy-duty applications can involve increased starting torque, frequent acceleration, high inertia or repeated overload conditions.

Potential applications include:

• Heavy conveyors
• Material-handling machinery
• High-inertia equipment
• Certain mining machinery
• Heavy process machinery

The heavy-duty rating is lower in horsepower because the drive must tolerate more demanding electrical and thermal operating conditions.

---

10. Frame 9 Construction

The Frame 9 designation indicates that this is a physically large, high-power drive.

Frame size is important for both electrical and mechanical planning.

A Frame 9 drive requires substantially more space than a compact variable-frequency drive.

Before installation, engineers should consider:

• Cabinet dimensions
• Cable routing
• Cable bending radius
• Ventilation
• Heat dissipation
• Maintenance clearance
• Floor loading
• Lifting arrangements
• Electrical access

---

11. Dimensions

The model is associated with an 800 mm deep MCC-style cabinet.

A practical dimensional reference is approximately:

The exact overall dimensions can depend on the final packaged configuration and installation arrangement.

For engineering drawings, panel fabrication and installation work, the dimensions of the actual supplied unit should always take precedence over a general catalog reference.

---

12. Weight

The complete equipment weight should be regarded as configuration dependent.

Large packaged drives can contain different cabinet and power-component arrangements, so the total shipping and installed weight can vary.

For lifting and transportation, the actual equipment shipping weight should be confirmed before moving the drive.

This is particularly important for a Frame 9 cabinet.

---

13. Air-Cooled Design

The drive uses an air-cooled design.

At a 595 A output rating, the amount of heat generated by the power electronics is significant.

The installation therefore requires adequate ventilation and heat removal.

Important environmental considerations include:

• Ambient temperature
• Airflow
• Cabinet ventilation
• Cooling fan operation
• Dust
• Humidity
• Room temperature
• Heat generated by adjacent equipment

The cooling path should be kept clean and unobstructed.

---

14. IP20 / Type 1 Protection

The configuration uses an IP20 / Type 1 style enclosure arrangement.

This means the equipment is intended for installation in a suitable protected industrial environment.

It should not be treated as a waterproof or outdoor enclosure.

The electrical room or cabinet should protect the equipment from:

• Rain
• Direct water
• Condensation
• Excessive dust
• Conductive contamination
• Corrosive substances
• Excessive humidity

---

15. EMC Filter Configuration

The 20G11LE595AN2NNNNN incorporates an EMC filter configuration.

This is useful in installations where electromagnetic compatibility is an important consideration.

Industrial facilities may contain many electrical devices operating simultaneously, including:

• Drives
• PLC systems
• Sensors
• Communication equipment
• Motor starters
• Instrumentation
• Computers
• Control networks

Good EMC design can help reduce unwanted electrical interference.

Proper cable routing, grounding and installation practices remain important even when filtering is provided.

---

16. AC Input with Precharge

The model uses an AC input with precharge arrangement.

Precharge is important in large DC-bus drive systems because it helps control the initial charging current when the drive is energized.

For a large-capacity drive, controlling the initial DC-bus charging process is an important part of the power architecture.

This is particularly relevant to high-power Frame 9 equipment.

---

17. Embedded EtherNet/IP

The drive provides embedded EtherNet/IP communication.

This allows it to be integrated into a larger industrial control network.

Typical information exchanged can include:

This makes the drive suitable for centralized automation systems.

---

The drive can provide controlled acceleration and adjustable running speed.

Potential applications include:

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

---

18.5 Mining Equipment

Large mining operations use high-power motors for material movement, ventilation and water handling.

Potential applications include:

• Ore conveyors
• Dewatering pumps

Applications can include:

• Conveyors
• Fans
• Blowers
• Pumps
• Material-handling equipment
• Dust-control systems

---

19. Product Advantages

---

20. Energy-Saving Potential

One of the major reasons for using a variable-frequency drive is to avoid operating a motor unnecessarily at full speed.

This is particularly valuable for centrifugal pumps and fans.

For suitable variable-torque applications, reducing motor speed can significantly reduce the power required by the machine.

Potential benefits include:

• Reduced motor speed
• Reduced throttling losses
• Better flow control
• Better pressure control
• Better process matching
• Reduced mechanical stress
• Potential reduction in energy consumption

Actual savings depend on the application and operating profile.

---

21. Mechanical Advantages

Large motors can produce substantial mechanical stress when started directly.

The drive can provide controlled acceleration.

This can reduce sudden mechanical loading on:

• Shafts
• Couplings
• Bearings
• Gearboxes
• Belts
• Conveyor structures
• Pump assemblies
• Fan assemblies

For large machines, smoother acceleration can improve overall operating behavior.

---

22. Process-Control Advantages

The drive allows motor speed to become a process-control variable.

Instead of simply switching a motor between OFF and ON, the motor can operate at an appropriate speed.

For example:

Pump application:

Low demand → low motor speed.

Medium demand → medium motor speed.

High demand → higher motor speed.

This gives the process system more flexibility.

---

23. Maintenance Advantages

The drive can provide useful operating information to the control system.

Maintenance personnel can monitor:

• Drive status
• Motor speed
• Output current
• Fault conditions
• Warning conditions
• Communication status

A good maintenance program should also include physical inspection.

---

24. Five Recommended Models from the Same Series

The following are useful related PowerFlex 755 configurations for comparison.

These models are useful when comparing drive capacity around the 595 A range.

The higher-current versions may be considered when the motor’s actual full-load current, overload requirements or duty cycle exceed the 595 A configuration.

---

25. Five Closely Related Models

The configuration characters should be checked carefully when selecting a replacement.

Two drives can have the same current rating while having different filtering, cabinet, input-protection or other configuration characteristics.

---

26. Five Popular Models from the Same Brand

34. Overall Product Evaluation

The 20G11LE595AN2NNNNN is a high-capacity industrial AC drive designed for demanding motor-control applications.

Its core specifications — 600 VAC class, 595 A, Frame 9, air-cooled construction and 800 mm deep MCC-style packaging — make it particularly suitable for large industrial machines.

The drive is well matched to applications such as large pumps, fans, blowers, conveyors, mining equipment, cement machinery, aggregate handling systems and large process equipment.

Its EMC filter configuration is useful where electromagnetic compatibility is an important consideration, while the embedded EtherNet/IP capability allows the drive to participate in an industrial automation network.

The different light-duty, normal-duty and heavy-duty ratings also make it possible to evaluate the same drive capacity against different mechanical load conditions.

For engineering purposes, the most important parameters are the 595 A output current, 600 VAC voltage class, motor full-load current, duty cycle and actual application torque requirement.

The mechanical side is equally important. The equipment is a large Frame 9 package with an 800 mm cabinet depth, and the complete installed weight should be confirmed in kg from the actual equipment configuration before transportation, lifting or floor-loading calculations.

In short, the 20G11LE595AN2NNNNN is best suited to large industrial installations where a high-power AC motor requires controlled speed, controlled acceleration, process flexibility and integration into an industrial automation system.
