4. Product Introduction

The 20G11LE980AN0NNNNN is designed for controlling very large AC motors used in industrial production and process equipment.

Unlike a simple motor starter, a variable frequency drive can control motor speed and acceleration.

This allows the motor to operate according to the requirements of the machine rather than simply running continuously at full speed.

The drive sits between the industrial electrical supply and the motor.

A typical power arrangement is:

Three-Phase AC Supply → Variable Frequency Drive → Three-Phase Motor

The control arrangement can also be connected to an automation network:

Industrial Controller → EtherNet/IP → Drive → Motor

This combination makes the drive suitable for large automated machinery, process equipment and plant-wide motor-control systems.

5. 980 A High-Power Rating

The most important feature of this model is its 980 A current rating.

This places the drive in the very high-power range.

The 980 A capacity makes it suitable for large motors where smaller PowerFlex configurations may not provide sufficient current capacity.

The rated horsepower varies according to duty classification.

Duty	Motor Rating
Light Duty	1,100 HP
Normal Duty	1,000 HP
Heavy Duty	900 HP
Rated Current	980 A
Voltage	600 VAC
Phase	3 Phase

The duty classification should always be considered together with the actual motor nameplate current and application load.

A 900 HP motor, for example, may have very different operating requirements depending on whether it drives a pump, conveyor, crusher, compressor or another type of machinery.

6. Light Duty, Normal Duty and Heavy Duty

Understanding the duty ratings is important when selecting this drive.

Light Duty

The Light Duty rating reaches approximately 1,100 HP.

This rating is generally associated with applications where the motor load and overload requirements are comparatively moderate.

Typical examples can include suitable fan and pump applications, subject to the actual motor and load characteristics.

Normal Duty

The Normal Duty rating is approximately 1,000 HP.

This provides a balance between motor power and application loading.

Large process machinery can fall into this category when the actual load profile is appropriate.

Heavy Duty

The Heavy Duty rating is approximately 900 HP.

Heavy-duty applications can require greater overload capability because the machine may experience high torque, high inertia or frequent load changes.

Applications such as heavy conveyors and certain material-processing systems should be evaluated according to the actual mechanical load.

8. Physical Dimensions

The catalog configuration is identified as an 800 mm deep MCC-style drive.

Therefore, the clearly established mechanical depth is:

800 mm

The total width and height can depend on the complete packaged arrangement and installation configuration.

For that reason, assigning an arbitrary width or height would not be appropriate.

Enclosure	Type 1 / IP20
Cooling	Forced Air
Depth	800 mm
Width	Configuration-dependent
Height	Configuration-dependent

9. Weight

The requested weight parameter is included here explicitly.

Weight Item	Value
Product Weight (kg)	Configuration-dependent
Shipping Weight (kg)	Configuration-dependent
Complete MCC Assembly Weight (kg)	Configuration-dependent
Installed System Weight (kg)	Configuration-dependent

For a Frame 9 high-power drive, the final mass can vary depending on the physical package and associated equipment.

For transportation, lifting and floor-loading calculations, the exact equipment configuration should be used rather than relying on an estimated number.

This is particularly important for a drive approaching the 1 MW-class motor range.

10. Cooling System

The drive uses forced-air cooling.

High-power semiconductor devices generate considerable heat while converting electrical energy for motor control.

The cooling system removes heat from the power section and helps maintain an appropriate operating temperature.

Adequate airflow is therefore an important part of installation planning.

The surrounding installation should provide sufficient ventilation and maintenance access.

Important considerations include:

• Ambient temperature
• Airflow
• Dust
• Moisture
• Ventilation
• Altitude
• Cabinet arrangement
• Cooling-fan condition
• Air inlet and outlet clearance

11. Enclosure

The specified configuration uses a Type 1 / IP20 enclosure arrangement.

This configuration is intended for appropriate industrial electrical environments.

It is generally more appropriate for protected electrical rooms, control areas and suitable MCC installations than for locations where the equipment is directly exposed to water, excessive dust or outdoor weather.

The installation environment should therefore be evaluated before the drive is selected.

12. 600 VAC Electrical System

The 600 VAC rating makes this model suitable for high-power industrial electrical systems.

Large motors are often operated at higher voltages because higher voltage can help manage the current required to transmit very large amounts of power.

With a 980 A rating, this drive is intended for substantial industrial motor loads.

13. Embedded EtherNet/IP

The model includes embedded EtherNet/IP communication.

This allows the drive to become part of a networked control system.

A controller can exchange operating commands and drive information with the variable frequency drive.

Typical information can include:

Data	Purpose
Run Command	Starts motor operation
Stop Command	Stops motor operation
Speed Reference	Sets desired speed
Actual Speed	Provides operating feedback
Output Frequency	Monitors drive frequency
Motor Current	Monitors motor loading
Drive Status	Shows operating state
Warning Status	Indicates abnormal conditions
Fault Status	Identifies fault conditions
Diagnostic Information	Supports troubleshooting

14. Industrial Automation Integration

A typical automation arrangement can be structured as:

Controller

↓

EtherNet/IP Network

↓

20G11LE980AN0NNNNN

↓

Large Three-Phase AC Motor

An operator interface can be used above the controller to provide centralized monitoring.

This is useful when a plant contains many large motors.

Instead of requiring operators to stand beside each drive, operating information can be presented at a central control location.

The complete installation should therefore consider:

• Grounding
• Bonding
• Motor cable routing
• Cable shielding
• Control-cable routing
• Power-cable separation
• Cabinet construction
• Motor cable length

20. Input Configuration

The model uses AC input with precharge and DC terminals.

33. Energy-Saving Potential

Variable-speed operation can provide energy-saving opportunities when the motor load changes according to process demand.

This is especially relevant to variable-torque applications.

For example, a large fan or pump may not need to operate at maximum speed continuously.

Reducing motor speed can reduce power consumption substantially in suitable applications.

Actual energy savings depend on:

• Motor efficiency
• Load characteristics
• Operating hours
• Process demand
• Speed range
• Mechanical efficiency
• Pump or fan characteristics
• Control strategy

34. Large-Motor Starting

Large motors can generate significant electrical and mechanical effects during startup.

The drive provides controlled acceleration instead of immediately applying full operating speed.

This can help reduce mechanical shock on:

• Shafts
• Couplings
• Gearboxes
• Belts
• Bearings
• Pulleys
• Other rotating components

35. Process Control Benefits

The drive can become part of the process-control system.

For example:

Pump → Flow Control

Fan → Airflow Control

Conveyor → Material Speed Control

Compressor → Process Capacity Control

Mixer → Mixing-Speed Control

This makes the variable frequency drive more than a simple motor starter.

It becomes an active component of the production process.
