Allen-Bradley 20G14TF460AN0NNNNN PowerFlex 755 AC Drive

1. Product Overview

The Allen-Bradley 20G14TF460AN0NNNNN is a high-power PowerFlex 755 air-cooled AC drive designed for demanding industrial motor-control applications.

It belongs to the PowerFlex 750 Series and the PowerFlex 755 product family. This particular configuration is part of the high-power TF range and is intended for large industrial motors, heavy machinery, continuous-process equipment, and engineered common-bus systems.

The drive is associated with the 690 VAC three-phase class and provides a 460 A current rating. Its high-power rating makes it suitable for applications requiring approximately 500 kW Light Duty, 450 kW Normal Duty, and 375 kW Heavy Duty capability.

The TF configuration is particularly important because it is designed around a DC-input / precharge architecture, making it different from a conventional standalone AC-line-input variable-frequency drive.

This type of configuration is especially useful in large installations where several drives may be integrated into a common DC-bus system.

The drive uses forced-air cooling and a large Frame 8 mechanical configuration. As a result, it is intended for industrial electrical rooms, drive cabinets, MCC-style installations, large machinery, and other engineered environments where sufficient ventilation, power distribution, cable space, and maintenance access are available.

The 20G14TF460AN0NNNNN is therefore best regarded as a high-capacity industrial motor-control platform rather than a compact general-purpose VFD.

The product is identified as a PowerFlex Air Cooled 755 AC Drive / PowerFlex 755 AC Packaged Drive.

The 460 A class places this model above the 415 A version and below the 500 A version within the immediate TF high-power range. The associated TF family provides a progressive set of current and power ratings for large motor applications.

4. Current and Power Ratings

The 20G14TF460AN0NNNNN is a high-capacity drive with a 460 A current class.

Its commonly associated duty ratings are:

Duty Classification	Approximate Current Class	Power Rating
Light Duty	500 A class	500 kW
Normal Duty	460 A class	450 kW
Heavy Duty	375 A class	375 kW

These different duty ratings are important when selecting the drive for an actual motor.

A drive should not be selected solely by looking at the motor’s nominal kW value. The actual motor full-load current, overload requirement, starting torque, acceleration time, operating speed, load inertia, and duty cycle all affect the correct selection.

For a large conveyor, crusher, compressor, or other constant-torque machine, Heavy Duty capability may be more important than simply matching the motor’s nameplate power.

For a large fan or centrifugal pump, the Normal Duty rating may provide a more appropriate reference depending on the operating conditions.

5. 690 VAC High-Voltage Class

The 20G14TF460AN0NNNNN belongs to the 690 VAC three-phase class.

This voltage class is commonly used for large industrial motors because increasing motor voltage allows a high-power motor to operate at a lower current than an equivalent motor at a much lower voltage.

Lower operating current can be beneficial for large installations because it can influence:

• Cable sizing.
• Busbar sizing.
• Switchgear selection.
• Transformer arrangement.
• Electrical losses.
• Cabinet architecture.
• Motor-terminal equipment.

The 690 VAC rating should be understood as the drive and motor/system voltage class. The TF configuration itself is associated with a DC-input architecture, so it should not be treated as an ordinary 690 VAC line-input drive without considering the complete electrical system.

6. DC Input and Precharge Architecture

One of the most significant characteristics of the 20G14TF460AN0NNNNN is its DC-input with precharge configuration.

This architecture is useful in high-power systems where several drives may share a common DC bus.

In a common-bus installation, multiple drive sections can be connected to a coordinated DC power system rather than treating every drive as a completely independent AC-input unit.

This can be especially valuable in large production lines where several motors operate together.

The precharge arrangement is important because the drive contains substantial DC-link capacitance.

When the DC bus is initially energized, the precharge system controls the charging process and limits the initial charging current.

For a large industrial system, the precharge function should be considered together with:

• DC-bus protection.
• Disconnecting equipment.
• Fusing.
• Bus voltage.
• Grounding.
• Capacitor discharge.
• Common-bus architecture.
• Emergency isolation.
• System-level protection.

The DC input architecture therefore makes this drive particularly suitable for engineered high-power systems rather than simple standalone installations.

7. Frame 8 Construction

The 20G14TF460AN0NNNNN uses a Frame 8 configuration.

Frame 8 indicates a large physical and electrical platform designed to accommodate substantially higher power than the smaller PowerFlex drive frames.

A Frame 8 installation requires careful mechanical and electrical planning.

Important considerations include:

• Cabinet width.
• Cabinet height.
• Cabinet depth.
• Cable bending radius.
• Power-terminal accessibility.
• Airflow path.
• Heat dissipation.
• Maintenance clearance.
• Drive removal space.
• Mechanical lifting.
• DC-bus connections.
• Grounding arrangements.

The exact physical dimensions should be taken from the applicable mechanical drawing for the final configuration because physical arrangements can vary depending on installation architecture and options.

For that reason, the safest product specification is:

Dimensions: Configuration-dependent

Weight: Configuration-dependent kg

This is preferable to inserting a generic Frame 8 measurement that may not correspond to the actual installed configuration.

8. Cooling System

The drive uses forced-air cooling.

Air cooling is a practical approach for large industrial drive systems because it avoids the additional complexity associated with liquid cooling.

The cooling system depends on a clean and adequately ventilated installation environment.

The surrounding cabinet should therefore be designed so that:

• Cool air can enter the drive area.
• Heated air can leave the enclosure.
• Airflow is not blocked by adjacent equipment.
• Dust accumulation is controlled.
• Ambient temperature remains within the permitted range.
• Cooling fans can be inspected and serviced.

In dusty environments such as mining, cement, aggregate, and bulk-material plants, cooling-system maintenance becomes particularly important.

A high-power drive can generate substantial heat, so cabinet ventilation should be treated as an essential part of the overall system design.

9. EMC Filtering

The catalog configuration is associated with an EMC Filter.

The filtering arrangement is important in industrial installations because high-power variable-frequency drives can generate electrical noise and high-frequency components.

A properly engineered filter and grounding arrangement can help reduce unwanted electrical interference and improve compatibility with surrounding control equipment.

This becomes increasingly important when the drive is installed close to:

• PLC systems.
• Analog instrumentation.
• Industrial Ethernet equipment.
• Temperature controllers.
• Pressure transmitters.
• Measurement equipment.
• Communication equipment.
• Safety systems.
• Other variable-frequency drives.

The final EMC performance depends not only on the drive itself but also on motor-cable construction, cable length, shielding, grounding, cabinet layout, and the overall installation.

10. Dynamic Braking

The 20G14TF460AN0NNNNN is specified with no dynamic braking.

This is an important consideration for applications involving large amounts of regenerative energy.

During deceleration, a high-inertia motor/load combination can return energy toward the drive’s DC bus.

If the application requires frequent rapid deceleration, the system designer should determine how this energy will be managed.

Applications that deserve particular attention include:

• High-inertia conveyors.
• Large centrifuges.
• Hoisting systems.
• Winders and unwinders.
• Rapid-cycle machinery.
• Large rotating equipment.
• Heavy material-handling systems.

For such applications, an external braking or regenerative-energy solution may need to be considered.

11. Human Interface

The specified configuration is associated with a blank / no HIM arrangement.

This is suitable for systems where the drive is primarily controlled through an automation network, PLC, DCS, SCADA system, or centralized operator station.

A local operator interface is not always necessary for large automated systems.

In a centralized plant, the operator may monitor:

• Motor speed.
• Motor current.
• Drive status.
• Fault conditions.
• Alarms.
• Output frequency.
• Torque.
• Operating commands.

through the plant’s control system rather than directly from the drive enclosure.

This can help keep large drive cabinets simpler and can support centralized operation.

12. Industrial Network Integration

The PowerFlex 755 platform is designed for integration into modern industrial automation systems.

Network-based control can be used for functions such as:

• Start and stop commands.
• Speed reference.
• Torque reference.
• Drive status.
• Fault monitoring.
• Alarm monitoring.
• Parameter management.
• Diagnostic information.
• Production information.
• Maintenance data.
• Remote troubleshooting.

This makes the drive suitable for large production lines where multiple high-power motors must operate together under coordinated control.

13. Product Introduction

The Allen-Bradley 20G14TF460AN0NNNNN PowerFlex 755 is designed for applications that require substantially more power than typical compact or medium-size variable-frequency drives.

Its combination of:

• 460 A current class.
• Approximately 450 kW Normal Duty capability.
• Approximately 375 kW Heavy Duty capability.
• 690 VAC system class.
• DC-input architecture.
• Precharge.
• Frame 8 construction.
• Forced-air cooling.
• EMC filtering.

makes it particularly appropriate for large industrial machinery.

The drive can be used as part of a centralized automation system or as a component within a larger common-bus architecture.

Its high-power capacity makes it particularly relevant to mining, cement, material handling, water infrastructure, heavy manufacturing, process industries, large ventilation systems, compressors, and large pumping systems.

14. Main Product Advantages

14.1 High Current Capacity

The 460 A current class gives the drive substantial motor-control capability.

This allows it to handle large industrial motors without relying on multiple smaller drives simply to obtain the necessary output capacity.

14.2 High Power Capability

The approximate 450 kW Normal Duty rating makes this drive suitable for large motors and high-capacity machinery.

For Heavy Duty applications, the approximately 375 kW rating provides a strong capacity for demanding constant-torque loads.

14.3 High-Voltage Operation

The 690 VAC class is well suited to large industrial motor systems.

Higher motor voltage can help reduce current for a given power level, which can be useful when designing large motor feeders and electrical distribution systems.

14.4 Common-Bus Compatibility

The DC-input architecture is one of the major advantages of this configuration.

It allows the drive to be considered as part of a common-bus system where multiple drive sections operate from a coordinated DC power architecture.

14.5 Precharge Capability

The integrated precharge arrangement supports controlled energization of the DC-link system.

This is particularly important for large drives with substantial DC-link capacitance.

14.6 Industrial Automation Integration

The PowerFlex 755 platform can be integrated into a wider industrial control system.

This allows drive operation, diagnostics, and monitoring to be incorporated into centralized automation.

14.7 Air-Cooled Design

Forced-air cooling is a familiar industrial technology and can be easier to maintain than a liquid-cooled system.

It is well suited to many industrial electrical rooms and machine cabinets when adequate ventilation is provided.

14.8 Flexible Duty Ratings

The Light Duty, Normal Duty, and Heavy Duty classifications provide more flexibility when matching the drive to the actual load.

This is especially useful because large industrial motors can have very different operating profiles even when their nameplate power ratings are similar.

14.9 Large Industrial Frame

Frame 8 construction provides the physical platform required for high-power applications.

This makes the drive appropriate for large industrial installations where compact drives would not provide enough current capacity.

15. Typical Applications

15.1 Mining Conveyors

Mining conveyors can require very large motors and substantial starting torque.

The 20G14TF460AN0NNNNN can be considered for high-capacity conveyor systems where controlled acceleration, speed regulation, and centralized monitoring are required.

15.2 Cement Production

Cement plants contain many large motors used for:

• Raw-material handling.
• Crushers.
• Fans.
• Conveyors.
• Process equipment.
• Material transfer.
• Large pumps.

The drive’s high-power capability makes it suitable for these types of engineered motor-control systems.

15.3 Large Pumps

Large pumps can benefit from variable-speed control.

Speed adjustment allows the pump to respond to process demand rather than operating continuously at one fixed speed.

This can improve process control and, under suitable operating conditions, reduce unnecessary energy consumption.

15.4 Large Fans

Large industrial fans often operate continuously.

Variable-speed control allows airflow to be adjusted according to actual process requirements.

Potential applications include:

• Furnace ventilation.
• Dust collection.
• Process cooling.
• Industrial ventilation.
• Mining ventilation.
• Cement-process fans.

15.5 Compressors

Large compressors can require carefully controlled acceleration and speed.

A high-power variable-frequency drive can provide controlled motor operation while integrating the compressor into a wider automated process.

15.6 Bulk Material Handling

The drive can be used in large material-handling systems such as:

• Belt conveyors.
• Transfer systems.
• Feeders.
• Bulk-material processing.
• Large production lines.

Controlled acceleration can help reduce mechanical shock to gearboxes, belts, couplings, and other mechanical components.

15.7 Heavy Manufacturing

Large industrial machines often require precise variable-speed motor control.

The PowerFlex 755 platform can be used where a high-power motor must operate under coordinated PLC or plant-control supervision.

17. Five Recommended Same-Series Models

The following five models are particularly relevant because they are part of the same high-power TF family or are immediately adjacent to the 20G14TF460AN0NNNNN in the same product range.

Model	Voltage Class	Current Class	Light Duty	Normal Duty	Heavy Duty	Frame
20G14TF330AN0NNNNN	690 VAC / 932 VDC class	330 A	355 kW	315 kW	250 kW	Frame 8
20G14TF370AN0NNNNN	690 VAC / 932 VDC class	370 A	400 kW	355 kW	300 kW	Frame 8
20G14TF415AN0NNNNN	690 VAC / 932 VDC class	415 A	450 kW	400 kW	355 kW	Frame 8
20G14TF460JN0NNNNN	690 VAC / 932 VDC class	460 A	500 kW	450 kW	375 kW	Frame 8
20G14TF500AN0NNNNN	690 VAC / 932 VDC class	500 A	530 kW	500 kW	400 kW	Frame 8

These models form a useful progression around the 460 A configuration and allow selection according to actual motor current and duty requirements. The catalog listings confirm the 330 A through 500 A TF model range.

18. Same-Series Model Comparison

Model	Current	Normal Duty	Heavy Duty	Relative Position
20G14TF330AN0NNNNN	330 A	315 kW	250 kW	Lower-power option
20G14TF370AN0NNNNN	370 A	355 kW	300 kW	Medium-high power
20G14TF415AN0NNNNN	415 A	400 kW	355 kW	High power
20G14TF460AN0NNNNN	460 A	450 kW	375 kW	Very high power
20G14TF500AN0NNNNN	500 A	500 kW	400 kW	Highest standard option in this group

The 20G14TF460AN0NNNNN is positioned toward the upper end of the standard TF Frame 8 range.

It is therefore a strong choice when the 415 A configuration is no longer sufficient but a 500 A configuration would provide more capacity than necessary.

19. Recommended Same-Series Alternatives

20G14TF330AN0NNNNN

This model is appropriate when the application requires the same general high-voltage TF architecture but has a smaller motor.

Its approximately 315 kW Normal Duty rating and 250 kW Heavy Duty rating make it suitable for substantial industrial machinery without moving all the way up to the 460 A class.

20G14TF370AN0NNNNN

The 370 A configuration provides approximately 355 kW Normal Duty and 300 kW Heavy Duty capability.

It is a practical middle option for applications where the 330 A configuration is insufficient but the 415 A or 460 A models would be larger than necessary.

20G14TF415AN0NNNNN

The 415 A version is one of the closest alternatives to the 460 A model.

Its approximately 400 kW Normal Duty rating and 355 kW Heavy Duty rating make it suitable when the application requires high power but does not require the full 460 A class.

20G14TF460JN0NNNNN

This model is particularly relevant because it shares the same basic 460 A high-power configuration while using a different catalog configuration suffix.

It can be considered when the filtering and CM-capacitor configuration associated with the JN version is required.

It should not, however, be treated as identical to the AN configuration without checking the complete catalog configuration.

20G14TF500AN0NNNNN

This is the next step upward from the 460 A version.

Its approximately 500 kW Normal Duty and 400 kW Heavy Duty capability makes it appropriate for applications requiring additional motor current and power capacity.

20. Five Popular Allen-Bradley Models for Comparison

The following models are useful comparison points from the same broad PowerFlex platform.

They are not direct replacements for the 20G14TF460AN0NNNNN; their voltage classes, current ratings, and electrical configurations differ.

Model	Product Series	Voltage Class	Current Class	General Application	Configuration Type
20G11GD034AA0NNNNN	PowerFlex 755	480 VAC class	34 A	Medium industrial machinery	AC-input
20G11GD052AA0NNNNN	PowerFlex 755	480 VAC class	52 A	Pumps, fans, conveyors	AC-input
20G11GD077AA0NNNNN	PowerFlex 755	480 VAC class	77 A	Medium/high-power machinery	AC-input
20G14TE510JN0NNNNN	PowerFlex 755	600 VAC class	510 A class	Large industrial equipment	High-power DC-input
20G14TD740JN0NNNNN	PowerFlex 755	High-voltage class	740 A class	Very large industrial systems	High-power DC/common-bus

The wider product catalog includes the TF, TE, TD, and other PowerFlex 755 configurations, allowing the platform to cover a broad range of motor sizes and electrical architectures.

21. Popular Model Comparison

Model	Approximate Application Level	Main Voltage Class	Current Class	Best-Suited Applications
20G11GD034AA0NNNNN	Medium	480 VAC	34 A	Pumps, fans, conveyors
20G11GD052AA0NNNNN	Medium	480 VAC	52 A	Machinery and process equipment
20G11GD077AA0NNNNN	Medium-high	480 VAC	77 A	Larger industrial motors
20G14TE510JN0NNNNN	Very high	600 VAC	510 A class	Large industrial equipment
20G14TD740JN0NNNNN	Extremely high	High-voltage	740 A class	Very large common-bus systems

22. Dimensions and Weight

Because the 20G14TF460AN0NNNNN is a large Frame 8 drive and its final physical arrangement can depend on the selected configuration, exact dimensions and weight should not be guessed.

Physical Parameter	Specification
Frame	Frame 8
Width	Configuration-dependent
Height	Configuration-dependent
Depth	Configuration-dependent
Overall Size	Configuration-dependent
Mounting Footprint	Configuration-dependent
Installed Weight	Configuration-dependent kg
Shipping Weight	Configuration-dependent kg
Cabinet Clearance	Configuration-dependent
Cable Entry Space	Configuration-dependent
Service Clearance	Configuration-dependent

For purchasing, cabinet design, transportation, lifting, and mechanical engineering, the exact mechanical drawing for the intended configuration should be used.

This is particularly important for Frame 8 equipment because cabinet arrangement, power connections, accessories, and installation configuration can affect the final dimensions and weight.

23. Installation Advantages

The 20G14TF460AN0NNNNN is well suited to engineered cabinet installations.

Its high-power design allows large motors to be controlled from a centralized electrical system while maintaining integration with industrial automation.

The installation should provide adequate:

• Ventilation.
• Electrical isolation.
• DC-bus protection.
• Grounding.
• Cable space.
• Motor-cable routing.
• Maintenance access.
• Thermal management.
• Network connectivity.
• Safety isolation.

The physical installation should also account for the weight and dimensions of the Frame 8 assembly.

Large drives may require appropriate mechanical handling equipment during installation or removal.

24. Maintenance Advantages

The air-cooled construction is relatively familiar to industrial maintenance teams.

Routine maintenance can focus on:

• Cooling fans.
• Air passages.
• Electrical connections.
• Grounding connections.
• Cabinet cleanliness.
• DC-bus condition.
• Drive alarms.
• Fault history.
• Network communications.
• Motor-cable condition.

In dusty environments, maintaining clean airflow paths is particularly important.

A clogged cooling path can increase operating temperature and reduce the reliability of power electronics.

Preventive maintenance should therefore be adjusted to the actual environment rather than using one universal inspection interval.

25. Energy and Process-Control Benefits

A variable-frequency drive can provide process advantages beyond simply changing motor speed.

For pumps and fans, reducing speed when full output is not required can reduce energy consumption under suitable operating conditions.

For conveyors, controlled acceleration can reduce mechanical shock.

For process machinery, speed control can improve production consistency.

For large motors, variable-speed control can also reduce the need for mechanical throttling or other inefficient control methods.

The actual energy savings depend on the load profile, motor efficiency, process requirements, operating speed, and overall system design.

26. Mechanical and Electrical Application Considerations

Before selecting the 20G14TF460AN0NNNNN, engineers should review the following:

Selection Factor	Recommended Check
Motor Voltage	Confirm 690 VAC class compatibility
Motor Current	Confirm actual full-load current
Motor Power	Compare with ND and HD ratings
Load Type	Constant torque or variable torque
Starting Torque	Determine required starting capability
Acceleration	Confirm required acceleration time
Deceleration	Determine braking-energy requirements
Inertia	Evaluate motor/load inertia
DC Bus	Confirm common-bus voltage
Precharge	Verify system-level precharge arrangement
Cooling	Verify ambient temperature and airflow
Environment	Check dust, humidity, vibration, altitude
Motor Cable	Check cable size, length and EMC requirements
Cabinet	Verify Frame 8 installation requirements
Network	Confirm automation architecture
Grounding	Verify complete system grounding
Maintenance	Provide sufficient service access

27. Why the 460 A Model Can Be a Good Selection

The 460 A version occupies an attractive position within the TF family.

A 330 A or 370 A model may not provide sufficient capacity for a large motor with significant overload requirements.

A 500 A model, on the other hand, may be unnecessarily large for a motor that fits comfortably within the 460 A class.

The 20G14TF460AN0NNNNN therefore provides a useful middle-high capacity option.

For an application around the 450 kW Normal Duty class, it offers a strong combination of motor capacity, high-voltage operation, common-bus architecture, and industrial automation compatibility.

28. Product Selection by Motor Size

Approximate Motor Requirement	Suggested TF Model	Comment
Around 250 kW ND	20G14TF265AN0NNNNN	Lower-power high-voltage option
Around 315 kW ND	20G14TF330AN0NNNNN	Medium-high power
Around 355 kW ND	20G14TF370AN0NNNNN	High-power option
Around 400 kW ND	20G14TF415AN0NNNNN	Higher-capacity option
Around 450 kW ND	20G14TF460AN0NNNNN	Very high-power option
Around 500 kW ND	20G14TF500AN0NNNNN	Highest standard option in this immediate group

Actual selection must be based on motor current and duty requirements rather than kW alone.

29. Key Advantages at a Glance

Feature	Benefit
460 A Current Class	Suitable for very large motors
Approximately 450 kW ND	Strong Normal Duty capability
Approximately 375 kW HD	Suitable for demanding loads
690 VAC Class	Appropriate for large industrial motors

Its 460 A current class, approximately 450 kW Normal Duty rating, approximately 375 kW Heavy Duty rating, 690 VAC class, Frame 8 construction, forced-air cooling, and DC-input/precharge architecture make it a strong candidate for demanding industrial machinery.

Its greatest advantage is the combination of high electrical capacity and compatibility with large engineered drive systems.

For mining conveyors, cement equipment, large pumps, industrial fans, compressors, bulk-material handling equipment, heavy manufacturing machinery, and other large motor-driven processes, this configuration provides a powerful variable-speed control platform.

The DC-input architecture is particularly useful when the drive is part of a common-bus system.

The 460 A class also provides a useful position within the TF family. Applications that need less capacity can move toward the 330 A, 370 A, or 415 A configurations, while applications requiring additional capacity can move to the 500 A version.

The most important point when selecting this drive is to match the drive to the actual motor current, duty cycle, overload requirements, load characteristics, DC-bus architecture, braking requirements, and installation environment.

For large industrial applications around the 450 kW Normal Duty range, the 20G14TF460AN0NNNNN is a particularly strong high-power configuration within the PowerFlex 755 family.
