Allen-Bradley 20G14TF415AN0NNNNN PowerFlex 755 AC Drive

1. Product Overview

The Allen-Bradley 20G14TF415AN0NNNNN is a high-power PowerFlex 755 AC Drive designed for large industrial three-phase motor-control applications.

It belongs to the PowerFlex 750 Series and specifically to the PowerFlex 755 product family. The unit is an air-cooled, open-type, high-power drive using Frame 8 construction.

The 20G14TF415AN0NNNNN is a 415 A class configuration intended for large 690 V-class motor systems. Its published duty ratings are approximately 450 kW for Light Duty, 400 kW for Normal Duty, and 355 kW for Heavy Duty.

This model is particularly appropriate for large conveyors, pumps, fans, blowers, compressors, mining equipment, cement and aggregate machinery, bulk-material handling systems, and other industrial machines where a conventional small or medium-size variable-frequency drive is not sufficient.

The catalog number also identifies a specific electrical configuration. The AN version is distinct from the corresponding JN configuration, so the two should not be treated as interchangeable simply because they share the same 415 A rating.

The 415 A current class places this model above the 370 A version and below the 460 A version in the same TF high-power range.

This makes it a useful selection when a 370 A drive does not provide enough current margin, but the application does not require the larger 460 A configuration.

---

4. Current and Power Ratings

The drive’s primary rating structure can be summarized as follows:

Duty Rating	Power Rating
Light Duty	450 kW
Normal Duty	400 kW
Heavy Duty	355 kW
Current Class	415 A

The difference between the three duty categories is important when selecting the drive.

A Light Duty application generally has lower overload requirements and can make use of the higher 450 kW rating.

A Normal Duty application has a more conventional industrial load profile and can be evaluated around the 400 kW level.

A Heavy Duty application has greater overload requirements and is evaluated around the 355 kW rating.

For this reason, the drive should not be selected solely by comparing the motor’s nameplate kW with the drive’s Light Duty rating.

The motor’s full-load current, overload requirement, acceleration requirements, load type, operating cycle, and mechanical inertia should all be considered.

---

5. 690 VAC-Class Operation

The 20G14TF415AN0NNNNN is intended for a 690 VAC-class motor system.

This voltage class is particularly useful in large industrial installations because high motor power can be achieved without requiring extremely high motor current.

For a large motor, reducing current can have practical benefits for electrical distribution equipment, busbars, motor feeders, cable sizing, and cabinet design.

The 690 V class also makes the model suitable for large motors commonly found in heavy industrial plants.

Typical examples include:

• Large pumps.
• Large fans.
• Compressors.
• Conveyors.
• Mining machinery.
• Cement-processing machinery.
• Bulk-material systems.
• Large process equipment.

---

6. DC Input and Common-Bus Architecture

The 20G14TF415AN0NNNNN is a DC-input configuration with precharge.

This is an important distinction when comparing this model with conventional AC-input drives.

The drive is designed to operate as part of a high-power DC-bus architecture.

In a common-bus system, multiple drive sections can share a DC power source.

This type of architecture can be particularly useful in large production systems where several motors operate together.

A properly engineered common-bus system can also make better use of regenerative energy.

For example, when one motor is accelerating while another motor is decelerating, energy returned by the decelerating motor can potentially be utilized elsewhere on the DC bus.

This can be an important advantage in multi-drive industrial systems.

Because the DC bus contains high electrical energy, the complete installation must be designed with appropriate protection, isolation, grounding, precharge, disconnect, and maintenance procedures.

---

7. Precharge Function

The DC-input architecture includes a precharge arrangement.

Precharge is important in a large DC-link system because the drive contains substantial DC-link capacitance.

When the system is energized, the precharge process controls the initial charging of the DC bus.

This reduces the electrical stress that could occur if a large capacitor bank were connected directly to the DC source without an appropriate charging sequence.

In a high-power installation, precharge should be considered as part of the complete electrical system rather than as an isolated drive feature.

---

8. Frame 8 Construction

The 20G14TF415AN0NNNNN uses Frame 8 construction.

Frame 8 is intended for high-power industrial installations and requires considerably more mechanical and thermal planning than small wall-mounted variable-frequency drives.

Important installation considerations include:

• Cabinet construction.
• Floor loading.
• Mounting structure.
• Cable routing.
• DC-bus connections.
• Motor connections.
• Cooling-air flow.
• Service access.
• Maintenance clearance.
• Lifting and handling.
• Grounding.
• Electrical separation.

For a large Frame 8 drive, the installation team should plan the handling method before the equipment arrives.

A suitable mechanical handling system is especially important because the complete drive assembly is significantly larger and heavier than low-power drive products.

---

9. Dimensions and Weight

The exact mechanical dimensions and weight should be confirmed against the final mechanical configuration and applicable dimensional drawing.

For product catalog purposes, the appropriate specification is:

Mechanical Parameter	Specification
Model	20G14TF415AN0NNNNN
Frame	Frame 8
Mounting	Floor-Mount / Cabinet Installation
Enclosure	Open Type
Width	Configuration-dependent
Height	Configuration-dependent
Depth	Configuration-dependent
Overall Dimensions	Configuration-dependent
Weight	Configuration-dependent kg
Cooling Clearance	Installation-dependent
Service Clearance	Installation-dependent
Handling Requirement	Heavy Industrial Equipment Handling

An exact weight should not be substituted with an estimated value because shipping weight, installed drive weight, cabinet arrangement, and associated hardware can vary according to the final configuration.

For an engineering drawing or cabinet layout, the exact dimensional information for the selected configuration should be used.

---

10. Cooling System

The drive uses forced-air cooling.

At this power level, thermal management is a major part of reliable operation.

Power semiconductors, bus components, and other internal components generate heat during operation.

The forced-air cooling system moves air through the drive and removes heat from the power section.

The installation should therefore provide sufficient airflow.

Important factors include:

• Ambient temperature.
• Cabinet ventilation.
• Cooling-air inlet.
• Exhaust-air path.
• Fan condition.
• Dust accumulation.
• Installation altitude.
• Motor loading.
• Switching frequency.
• Continuous current.
• Overload operation.

A high-power air-cooled drive should not be installed without considering the total thermal load of the cabinet.

---

11. EMC Filter Configuration

The catalog configuration specifies an EMC filter.

This is relevant to the electrical noise characteristics of the drive installation.

At high power, electromagnetic compatibility becomes increasingly important because the drive uses high-energy switching devices and can be connected to long motor cables.

The overall installation should therefore consider:

• Grounding.
• Motor cable routing.
• Shielding.
• Cable separation.
• Cabinet bonding.
• Control cable routing.
• Common-mode behavior.
• Motor cable length.

The EMC filter should be considered together with the complete installation rather than as an independent component.

---

12. Embedded EtherNet/IP

The PowerFlex 755 platform provides embedded EtherNet/IP communication capability.

This allows the drive to communicate with the larger industrial automation system.

Typical information that can be exchanged includes:

• Start and stop commands.
• Speed references.
• Drive status.
• Output frequency.
• Motor current.
• Fault status.
• Alarm status.
• Operating conditions.
• Diagnostic information.
• Control parameters.

For a large production system, this capability can reduce the need for extensive point-to-point wiring.

The drive can become an integrated part of the automation architecture rather than operating as an isolated motor controller.

This is especially useful in plants where multiple large motors are controlled from a centralized automation system.

---

13. HIM Configuration

The catalog configuration is specified as Blank / No HIM.

This means a standard local human-interface module is not included in the basic catalog configuration.

This can be suitable for applications where the drive is installed inside a cabinet and controlled primarily through an industrial network or external control system.

For large automated installations, a no-HIM configuration can provide a cleaner cabinet arrangement.

If local commissioning or operator access is required, the appropriate interface equipment can be selected separately according to the project requirements.

---

14. Dynamic Braking

The 20G14TF415AN0NNNNN is specified with no dynamic braking.

This means the basic catalog configuration does not include an integrated dynamic-braking arrangement.

The drive can still perform controlled acceleration and deceleration.

However, applications with high inertia or frequent deceleration should be evaluated for regenerative energy.

Potentially demanding applications include:

• Large conveyors.
• High-inertia fans.
• Centrifugal machines.
• Hoists.
• Downhill conveyors.
• Large rotating equipment.
• Material-handling systems.

Where substantial regenerative energy is generated, the system designer should determine whether an external braking solution or regenerative energy-management arrangement is necessary.

---

15. Product Introduction

The Allen-Bradley 20G14TF415AN0NNNNN is designed for large industrial motor-control systems where high current capacity and reliable variable-speed control are required.

It combines a 415 A current class with a 690 V-class motor system and high-power Frame 8 construction.

The drive is intended for applications where the motor is too large for conventional compact drives and where the system requires a more sophisticated industrial control platform.

The PowerFlex 755 family is well suited to applications requiring adjustable motor speed, controlled acceleration, controlled deceleration, motor protection, fault monitoring, industrial networking, and integration with a plant-level automation system.

The 20G14TF415AN0NNNNN is therefore more than a simple frequency converter. It is a high-power motor-control component intended to become part of a larger industrial electrical and automation system.

---

16. Main Product Advantages

16.1 High Current Capacity

The most obvious advantage is the 415 A current class.

This allows the drive to control large industrial motors and provides an important step up from the 330 A and 370 A configurations in the same product range.

For large motor applications, current capacity is often more important than simply comparing nominal kW values.

---

16.2 High Power Capability

The drive offers approximately:

• 450 kW Light Duty.
• 400 kW Normal Duty.
• 355 kW Heavy Duty.

This makes it suitable for a broad range of large industrial loads.

---

16.3 690 V-Class Motor Compatibility

The 690 V class makes the drive particularly suitable for large industrial motor systems.

Higher motor voltage helps control current at high power levels and can be beneficial for large plant electrical distribution systems.

---

16.4 Common-Bus Capability

The DC-input configuration is well suited to common-bus installations.

This can be valuable in systems containing several drives where coordinated energy management is required.

Common-bus architecture can also provide an efficient method of distributing DC power among multiple drive sections when properly engineered.

---

16.5 Flexible Duty Selection

The Light Duty, Normal Duty, and Heavy Duty ratings allow the same drive family to be considered for different mechanical load profiles.

This makes it easier for engineers to match drive capacity to the actual machine rather than relying on one universal motor-power value.

---

16.6 Industrial Network Integration

Embedded EtherNet/IP provides an effective method of connecting the drive to an industrial control system.

This can improve monitoring, diagnostics, command management, and machine-level coordination.

---

16.7 Scalable Product Family

The PowerFlex 755 range includes several closely related current ratings.

This makes it possible for an industrial facility to standardize on a common drive platform while using different current capacities for different machines.

For example, a smaller conveyor may use a 265 A or 330 A configuration, while a larger process machine may use a 415 A or 460 A configuration.

---

17. Typical Applications

Large Conveyor Systems

Large conveyors are a natural application for a 415 A class high-power drive.

Conveyors can have high inertia, especially when transporting large quantities of material.

Controlled acceleration can reduce mechanical shock and improve the starting characteristics of the complete conveyor system.

The drive can also provide adjustable speed according to production requirements.

Applications include:

• Mining conveyors.
• Cement conveyors.
• Aggregate conveyors.
• Port material handling.
• Bulk-material handling.
• Large factory conveyors.

---

Mining Machinery

Mining applications frequently involve high-power motors.

Potential applications include:

• Ore conveyors.
• Crushers.
• Large pumps.
• Ventilation fans.
• Material feeders.
• Processing machinery.
• Bulk-material handling.

The high-power architecture of the PowerFlex 755 makes it suitable for many large mining motor applications when environmental requirements are properly addressed.

---

Cement and Aggregate Plants

Cement and aggregate facilities contain numerous large motor loads.

Typical applications include:

• Crushers.
• Conveyors.
• Fans.
• Blowers.
• Mills.
• Feeders.
• Pumps.
• Material-processing machinery.

The ability to integrate the drive into a larger control network is useful in centralized plant automation.

---

Large Pumping Systems

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

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

This can provide better control of:

• Flow.
• Pressure.
• Process output.
• Pump operating point.
• System response.

The actual energy benefit depends on the pump design and system operating conditions.

---

Large Fans and Blowers

Large fans and blowers can also require substantial motor power.

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

Applications can include:

• Industrial ventilation.
• Mine ventilation.
• Furnace systems.
• Cement-process fans.
• Exhaust systems.
• Cooling systems.
• Combustion-air systems.

---

Compressors

Large compressors require carefully controlled motor operation.

The drive can provide variable-speed control where the compressor and motor are designed for such operation.

Acceleration and deceleration requirements should be evaluated carefully because compressors can have substantial mechanical and process-related loading.

---

18. Material-Handling Equipment

The drive can be considered for large material-handling systems where motor speed needs to be adjusted according to production demand.

Potential applications include:

• Bulk-material feeders.
• Large conveyors.
• Transfer systems.
• Loading systems.
• Processing lines.
• Industrial handling machinery.

The high current rating provides additional capacity for applications with substantial mechanical loads.

---

19. Manufacturing Applications

Large manufacturing plants often contain several high-power motors.

The 20G14TF415AN0NNNNN can be used where a machine requires a high-power variable-speed motor controller.

Possible applications include:

• Process lines.
• Large production machines.
• Cooling systems.
• Large pumps.
• Industrial fans.
• Material-handling equipment.
• Heavy processing equipment.

The network communication capability can also allow the drive to be integrated into centralized production control.

---

20. Advantages in Multi-Drive Systems

The DC-input architecture is particularly interesting in multi-drive systems.

A production line may contain several motors operating at different points in the process.

For example, one motor may accelerate while another decelerates.

With a properly engineered common DC bus, energy can be transferred between drive sections.

This can reduce the amount of energy that needs to be dissipated through conventional braking methods.

It can also provide a more coordinated electrical architecture for large systems.

The actual energy-management benefits depend on the complete system design and should be evaluated during engineering.

---

21. Installation Considerations

The 20G14TF415AN0NNNNN should be installed by personnel experienced with high-power variable-frequency drives and industrial electrical systems.

The installation should provide suitable:

• Mechanical support.
• Electrical protection.
• Grounding.
• Ventilation.
• DC-bus protection.
• Cable routing.
• Service access.
• Maintenance clearance.
• Environmental protection.

The cabinet should be designed around the heat generated by the drive as well as the heat generated by other equipment inside the enclosure.

The installation must also account for the high energy stored in the DC bus.

---

22. Maintenance Considerations

Routine maintenance should include inspection of the cooling system and electrical connections.

Important maintenance items include:

• Cooling fans.
• Air passages.
• Electrical terminals.
• DC-bus connections.
• Motor connections.
• Grounding connections.
• Cabinet ventilation.
• Dust accumulation.
• Signs of overheating.
• Network connections.

A clean cooling path is especially important for a high-power air-cooled drive.

In dusty industrial environments, periodic cleaning and inspection can be critical to maintaining thermal performance.

32. Final Product Evaluation

The Allen-Bradley 20G14TF415AN0NNNNN is a high-power PowerFlex 755 drive positioned for demanding industrial motor-control applications.

Its 415 A current class, 450 kW Light Duty, 400 kW Normal Duty, and 355 kW Heavy Duty ratings make it suitable for large motors and substantial mechanical loads.

The combination of 690 V-class operation, Frame 8 construction, forced-air cooling, DC input with precharge, EMC filtering, and embedded EtherNet/IP gives the drive a strong position in large industrial automation systems.

It is particularly suitable for large conveyors, pumps, fans, compressors, mining machinery, cement and aggregate equipment, bulk-material handling systems, and large manufacturing or process machines.

The DC-input/common-bus arrangement is also an important advantage for multi-drive installations where coordinated DC-bus energy management is required.

The 20G14TF415AN0NNNNN is best selected according to the motor’s actual current, duty, overload, acceleration, deceleration, regenerative-energy requirements, and electrical architecture.

For a 400 kW-class industrial motor system, this model provides a substantial combination of power capacity and industrial control capability while remaining within the same scalable PowerFlex 755 platform as the smaller 265 A, 330 A, and 370 A models and the larger 460 A configuration.

For cabinet design, transportation, installation, and procurement, the exact mechanical dimensions and final weight should always be taken from the selected configuration rather than estimated from the nominal frame designation.
