20G11TC460AN0NNNNN PowerFlex 755 AC Drive — Detailed Product Introduction, Specifications, Applications and Model Recommendations

1. Product Overview

The 20G11TC460AN0NNNNN is a high-power industrial AC variable frequency drive belonging to the PowerFlex 755 series.

It is designed for large three-phase motor applications where high output current, controlled motor speed, industrial automation integration and reliable power conversion are required.

This model is substantially larger and more powerful than the smaller PowerFlex 755 drives commonly used for low- and medium-power machinery.

The catalog configuration is associated with a 400 VAC three-phase power system, with a 460 A normal-duty output rating, a 250 kW normal-duty rating, and a 200 kW heavy-duty rating.

It is also capable of approximately 540 A light-duty operation at 315 kW, depending on the applicable operating-duty classification.

The drive is an IP00 / NEMA/UL Open Type Frame 8 power-conversion assembly.

Because of its high-power rating, it is intended for floor-mounted or cabinet-integrated industrial installations rather than compact machine-mounted applications.

The model is particularly appropriate for large industrial machinery where a conventional small variable frequency drive would not provide sufficient current or power capacity.

Typical application areas include large conveyors, pumps, fans, compressors, material-handling systems, process equipment, large mixers, industrial machinery and other high-power motor-driven systems.

---

5. Electrical Rating Details

The 20G11TC460AN0NNNNN is a particularly high-current PowerFlex 755 configuration.

Its ratings can be divided into three operating-duty categories.

Duty Classification	Continuous Output	1-Minute Overload	3-Second Overload	Power Rating
Light Duty	540 A	540 A class	594 A class	315 kW
Normal Duty	460 A	506 A	693 A	250 kW
Heavy Duty	385 A	578 A	693 A	200 kW

The normal-duty rating is particularly important for general industrial motor applications.

At normal duty, the drive is rated for approximately 460 A continuous output and approximately 250 kW.

For heavy-duty applications, the continuous rating is approximately 385 A, with a corresponding power rating of approximately 200 kW.

The light-duty rating increases the available continuous output to approximately 540 A and the corresponding power capability to approximately 315 kW.

The correct duty classification should always be selected according to the actual motor load, overload profile, acceleration requirements and operating cycle.

---

6. Input Voltage

The model is associated with a 400 VAC three-phase input class.

The applicable input range is approximately 360–440 VAC.

This makes it suitable for industrial electrical systems designed around 380/400/415 VAC three-phase power.

It should not be confused with the 480 VAC configurations of the same product family.

The voltage class is an important selection parameter because PowerFlex 755 catalog numbers can look very similar while being intended for different electrical systems.

---

7. Output Current

The principal normal-duty output rating is:

460 A

This is a very high output-current rating for an industrial variable frequency drive.

The high current capacity makes the model suitable for large motors and large mechanical systems.

The actual motor selection should be based on the motor nameplate current rather than simply selecting the drive based on horsepower.

This is especially important for large industrial motors because motor current can vary significantly depending on motor efficiency, power factor, voltage, duty class and operating conditions.

---

8. Power Rating

The principal normal-duty rating is:

250 kW

The heavy-duty rating is:

200 kW

The light-duty rating is:

315 kW

Rating	kW	Approx. HP Equivalent
Light Duty	315 kW	Approx. 422 HP
Normal Duty	250 kW	Approx. 335 HP
Heavy Duty	200 kW	Approx. 268 HP

The horsepower figures are approximate conversions.

For actual equipment selection, the electrical current rating and motor nameplate information should take priority over a simple kW-to-HP conversion.

---

9. Frame 8 Construction

The 20G11TC460AN0NNNNN uses Frame 8 construction.

Frame 8 is intended for high-power applications and is physically very different from smaller PowerFlex 755 frames.

A Frame 8 installation requires substantial mechanical and electrical infrastructure.

The drive is designed for floor-mounted installation and cabinet integration.

The large physical size is necessary to accommodate:

• High-current power components
• Semiconductor switching equipment
• DC bus components
• Cooling systems
• Power connections
• Mechanical supports
• Electrical isolation
• Protective equipment
• Airflow paths

The installation therefore needs to be planned as part of the complete electrical room or motor-control system.

---

10. Dimensions and Weight

Because this is a Frame 8 high-power drive, dimensions depend on the enclosure arrangement.

For the IP00 open-type drive assembly, commonly specified approximate dimensions are:

Height: 2145 mm

Width: 778 mm

Depth: 425 mm

The open drive assembly can weigh up to approximately:

286 kg

For an IP20 NEMA/UL Type 1 MCC-style cabinet configuration, the approximate overall dimensions are:

Height: 2453 mm

Width: 600 mm

Depth: 600–800 mm

The approximate cabinet weight is:

623 kg

Mechanical Parameter	Open IP00 Drive	IP20 Cabinet Configuration
Model	20G11TC460AN0NNNNN	20G11TC460AN0NNNNN
Frame	Frame 8	Frame 8
Height	Approx. 2145 mm	Approx. 2453 mm
Width	Approx. 778 mm	Approx. 600 mm
Depth	Approx. 425 mm	Approx. 600–800 mm
Enclosure	IP00	IP20 / NEMA Type 1
Cooling	Forced air	Forced air
Weight (kg)	Approx. 286 kg	Approx. 623 kg

The difference between the two weights is important.

The 286 kg figure represents the approximate open drive assembly, while the approximately 623 kg figure represents the larger cabinet-style configuration.

Cabinet accessories, filters, options and auxiliary equipment can increase the installed weight.

---

11. Product Introduction

The 20G11TC460AN0NNNNN is designed for applications where a large AC motor must be controlled accurately and efficiently.

Unlike a simple motor starter, a variable frequency drive can control motor speed by changing the output frequency and voltage.

This allows the motor to operate at different speeds according to production requirements.

For a large industrial system, variable-speed operation can provide important benefits.

The motor does not necessarily need to run continuously at maximum speed.

Instead, the drive can adjust motor operation according to:

• Process demand
• Production rate
• Material flow
• Pressure
• Temperature
• Machine speed
• Load conditions
• Feedback signals

The PowerFlex 755 architecture also allows the drive to become part of a larger automation system.

This is especially useful in factories where multiple drives, PLCs, HMIs and process-control systems need to operate together.

---

12. Embedded EtherNet/IP

Embedded EtherNet/IP is an important feature of this configuration.

It allows the drive to communicate with an industrial automation system without requiring a separate external communication adapter for basic network integration.

A typical architecture may look like:

Industrial Controller

↓

EtherNet/IP Network

↓

20G11TC460AN0NNNNN

↓

Large Three-Phase Motor

↓

Industrial Machine

The controller can send commands such as:

• Start
• Stop
• Speed reference
• Direction
• Enable
• Reset
• Operating mode

The drive can return information such as:

• Output frequency
• Motor current
• Motor speed
• Drive status
• Warning information
• Fault information
• Diagnostic information

This type of communication can significantly simplify large automated systems.

---

13. Dynamic Braking

The catalog configuration has:

Dynamic Braking: None

This is an important distinction.

The drive should not be described as having an internal dynamic-braking transistor.

If the application requires rapid deceleration or regeneration management, the braking system must be designed separately according to the application.

Large rotating machinery can contain substantial kinetic energy.

When a large motor decelerates, energy may return to the DC bus.

The braking strategy therefore needs to be evaluated carefully for applications involving:

• High-inertia loads
• Rapid stopping
• Vertical machinery
• Large conveyors
• Centrifuges
• Hoists
• Rollers
• Frequent acceleration/deceleration

A suitable external braking or regenerative solution may be required depending on the application.

---

14. Filtering Configuration

The model uses a filtered configuration.

The catalog configuration also identifies the CM capacitor jumper as removed.

This type of configuration can be important when designing a large industrial electrical system.

Large drives can interact with:

• Transformers
• Motor cables
• Other drives
• PLC equipment
• Sensors
• Communication networks
• Instrumentation
• Grounding systems

Proper cable routing, grounding and shielding remain important even when filtering is included.

---

15. No-HIM Configuration

The model is configured as:

Blank / No HIM

This means the drive does not include a local Human Interface Module as part of this catalog configuration.

This arrangement is useful when the drive is controlled and monitored from a central automation system.

For example:

PLC → EtherNet/IP → Drive

or:

SCADA → PLC → Drive

The absence of a local HIM can also make sense in large electrical rooms where the drive is installed inside a centralized motor-control system.

---

16. Product Applications

16.1 Large Conveyors

Large conveyor systems are one of the most suitable application categories for a high-power drive of this type.

Large conveyors may involve:

• Long transport distances
• Heavy materials
• High motor power
• Large rotating inertia
• Multiple drive sections
• Variable production rates
• Controlled acceleration
• Controlled deceleration

The drive can adjust motor speed according to the production requirement.

For example, a mining conveyor may need to operate at different speeds depending on material flow.

A variable frequency drive can provide the required flexibility.

---

17. Mining and Bulk Material Handling

High-power drives are commonly associated with large material-handling systems.

Potential applications include:

• Ore conveyors
• Bulk material conveyors
• Crushers
• Feed systems
• Transfer systems
• Stockpile conveyors
• Large processing machines

These applications can involve very high mechanical loads.

The drive must therefore be selected according to motor current, overload requirements and mechanical duty.

---

18. Large Pumps

Large industrial pumps can require hundreds of kilowatts of motor power.

The 20G11TC460AN0NNNNN can be used in suitable pump applications where the motor rating and electrical system match the drive.

Possible applications include:

• Water transport
• Industrial water systems
• Cooling-water systems
• Process circulation
• Wastewater systems
• Large process pumps

Variable-speed operation allows pump output to be adjusted according to process demand.

This can reduce unnecessary operation at maximum speed.

---

19. Large Fans and Blowers

Large industrial fans and blowers can also benefit from variable-speed control.

Applications can include:

• Industrial ventilation
• Furnace air systems
• Process ventilation
• Exhaust systems
• Cooling systems
• Large air-handling equipment

The ability to vary motor speed allows the airflow to be adjusted according to process requirements.

---

20. Compressors

Large compressors can require substantial motor power.

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

Potential applications include:

• Industrial air systems
• Process gas systems
• Large mechanical compressors
• Plant utility systems

The exact drive selection should take into account compressor type, motor characteristics and required starting torque.

---

21. Process Machinery

The drive can also be considered for large process machinery.

Examples include:

• Mixers
• Agitators
• Process rollers
• Material-processing equipment
• Large production machines
• Industrial rotating equipment

Variable-speed operation can allow the production process to be adjusted without changing mechanical transmission components.

---

22. Advantages of the 20G11TC460AN0NNNNN

22.1 High Power Capacity

The most obvious advantage is the high power capability.

A 250 kW normal-duty rating makes the drive appropriate for large industrial motors.

The 315 kW light-duty rating provides additional capacity for applications with less demanding overload requirements.

---

The normal-duty output current is approximately:

460 A

This allows the drive to control large three-phase motors.

---

---

22.7 Forced-Air Cooling

Forced-air cooling allows the high-power electronics to dissipate substantial heat.

For large industrial installations, cooling design is a critical part of reliability.

---

22.8 Flexible Installation

The drive can be incorporated into larger cabinet and motor-control structures.

This makes it suitable for centralized industrial electrical rooms.

---

22.9 No Local HIM

The no-HIM configuration is useful when the drive is intended to be controlled from a centralized automation system.

---

22.10 Industrial Diagnostics

A network-connected drive can provide valuable operational information to the control system.

This can help maintenance personnel identify:

• Overcurrent conditions
• Overvoltage conditions
• Drive faults
• Motor loading
• Operating status
• Communication problems
• Thermal conditions

---

24. Mechanical Installation

The 20G11TC460AN0NNNNN is not a lightweight machine-mounted component.

It is a large industrial power assembly that requires proper floor support.

The installation area should be designed for:

• Drive weight
• Cabinet weight
• Cable weight
• Motor cable routing
• Incoming power connections
• Cooling airflow
• Maintenance access
• Safe working clearance
• Mechanical anchoring
• Grounding

The installation surface should be level, stable and capable of supporting the equipment.

---

25. Cooling Requirements

Because the drive is rated at hundreds of kilowatts, heat management is especially important.

The cooling system must be capable of removing the heat generated by:

• Power semiconductors
• Switching devices
• DC bus components
• Control electronics
• Auxiliary components

The ventilation system should be kept clean.

Dust, metallic particles and corrosive contaminants can reduce cooling performance and shorten equipment life.

The installation environment should therefore be considered carefully.

---

26. Typical Control Architecture

A large industrial installation may use the following structure:

Plant Control System

↓

PLC

↓

Industrial Ethernet

↓

PowerFlex 755

↓

460 A / 250 kW-Class Motor

↓

Large Mechanical Load

The PLC can coordinate the drive with other equipment.

For example, a conveyor drive could receive a speed reference based on upstream material flow.

A pump drive could receive a speed command based on pressure.

A fan drive could receive a command based on airflow or temperature.

A process drive could receive speed references from an HMI.

---

27. Maintenance Advantages

A networked high-power drive can provide useful diagnostic information.

Maintenance personnel can monitor:

• Drive operating status
• Motor current
• Output frequency
• Speed reference
• Actual speed
• Fault conditions
• Warning conditions
• Communication status

This makes troubleshooting more systematic.

Instead of relying only on physical inspection, maintenance teams can use operating data to determine where a problem may be occurring.

---

---

40. Important Limitations

The drive’s high power rating is also a limitation in some applications.

It is not economical or practical to use such a large drive for a small motor.

For example, using a Frame 8 drive for a 5 HP motor would create unnecessary:

• Cost
• Cabinet space
• Electrical infrastructure
• Cooling requirements
• Installation complexity
• Maintenance requirements

The correct application is therefore a large motor system where the required current and power justify the physical size and electrical infrastructure.

---

41. Installation Environment

The drive should be installed in an appropriate industrial environment.

Important environmental considerations include:

• Ambient temperature
• Humidity
• Dust
• Corrosive gases
• Vibration
• Altitude
• Air quality
• Ventilation
• Condensation
• Direct sunlight
• Foreign conductive material

Large power electronic equipment is particularly sensitive to excessive dust and poor cooling.

A clean, dry and adequately ventilated installation environment is strongly preferred.

---

42. Cable and Grounding Considerations

High-current drives require careful electrical engineering.

The installation should consider:

• Input cable size
• Motor cable size
• Grounding conductor
• Cable termination
• Shielding
• Cable routing
• Separation between power and control wiring
• Ethernet cable routing
• Motor cable length
• Electromagnetic compatibility
• Protective devices

The motor cable should be selected according to the actual motor current, installation method, temperature and applicable electrical requirements.

43. Large Motor Application Example

Consider a 250 kW industrial motor used to drive a large conveyor.

A typical control arrangement could be:

Incoming 400 VAC Three-Phase Power

↓

Protection and Isolation

↓

20G11TC460AN0NNNNN

↓

250 kW Motor

↓

Large Conveyor

The PLC can provide the speed reference through the industrial network.

The drive controls motor speed according to the command.

The drive can return operational information to the controller.

If the conveyor load changes, the control system can adjust motor speed accordingly.

This creates a flexible automated production system.

---

44. Large Pump Application Example

A large process pump can operate at different speeds depending on process demand.

For example:

Low process demand

→ Lower motor speed

Normal process demand

→ Medium motor speed

High process demand

→ Higher motor speed

This type of operation can provide better process control than simply operating the motor at a fixed speed.

The actual pump and motor must, of course, be compatible with variable-speed operation.

---

45. Large Fan Application Example

A large industrial fan may require different airflow rates during different production stages.

Instead of continuously running the motor at maximum speed, the drive can regulate motor speed.

For example:

Process Condition	Motor Speed Command
Low airflow demand	Low
Normal airflow demand	Medium
High airflow demand	High
Emergency process condition	Application dependent

This provides flexible airflow management.

48. Overall Technical Evaluation

The 20G11TC460AN0NNNNN is a high-capacity industrial variable frequency drive intended for large motor applications.

Its defining characteristic is its combination of approximately 460 A normal-duty output capacity and 250 kW normal-duty power.

It also provides approximately 385 A heavy-duty output at 200 kW, as well as approximately 540 A light-duty output at 315 kW.

The model uses a Frame 8 architecture.

This makes it physically much larger than the smaller PowerFlex 755 models.

The approximate open-drive dimensions are around 2145 × 778 × 425 mm, while a cabinet-mounted configuration can have an approximate height of 2453 mm.

The open drive assembly can weigh approximately 286 kg, while a complete IP20 cabinet configuration can reach approximately 623 kg.

Therefore, mechanical installation must be planned carefully.

The drive is particularly well suited to:

• Large conveyors
• Mining equipment
• Bulk material handling
• Large pumps
• Industrial fans
• Large blowers
• Compressors
• Process machinery
• Large mixers
• Industrial rollers
• High-power production equipment

Its embedded EtherNet/IP capability makes it suitable for integration into modern industrial automation systems.

The no-HIM configuration is appropriate for installations where operation and monitoring are performed from a PLC, HMI or supervisory control system.

One important characteristic is that the catalog configuration does not include dynamic braking.

Applications requiring rapid deceleration should therefore be evaluated separately for braking or regenerative requirements.

The model should be selected primarily according to the motor’s actual nameplate current, duty class and application load rather than by horsepower alone.

For applications requiring somewhat more capacity while remaining within the same Frame 8 family, the 20G11TC540AN0NNNNN, 20G11TC567AN0NNNNN, 20G11TC650AN0NNNNN, 20G11TC750AN0NNNNN and 20G11TC770AN0NNNNN provide logical comparison points.

For smaller industrial applications, lower-power PowerFlex 755 configurations or compact PowerFlex 525 models can be more practical.

Overall, the 20G11TC460AN0NNNNN should be regarded as a large industrial high-power AC drive for approximately 200–315 kW class motor applications, with the exact operating range determined by the selected duty classification.

Its major strengths are high current capacity, high power capability, advanced industrial drive functionality, network integration, flexible control and suitability for large automated motor systems.

For a large factory, processing plant or heavy-duty material-handling installation, these characteristics make it a strong choice when the motor and electrical infrastructure fall within its rating range.
