Allen-Bradley 20G1ANF171JN0NNNNN PowerFlex 755 AC Drive

1. Product Overview

The Allen-Bradley 20G1ANF171JN0NNNNN is a high-power air-cooled AC drive from the PowerFlex 755 series, designed for demanding industrial motor-control applications requiring high voltage, high current capacity, reliable speed regulation, and flexible automation integration.

This model is rated for 690 VAC, three-phase operation and provides a continuous output-current class of 171 A. It is rated at approximately 160 kW under Normal Duty (ND) and 132 kW under Heavy Duty (HD) conditions.

The drive uses a Frame 7 power section and a forced-air cooling system, making it suitable for larger industrial installations where motor loads, process equipment, pumps, fans, conveyors, compressors, and other rotating machinery require controlled acceleration, deceleration, speed regulation, and torque management.

The 20G1ANF171JN0NNNNN is configured with an AC input with precharge and no DC terminals, an IP20/IP00 open-type enclosure, integrated filtering with the CM jumper installed, embedded EtherNet/IP communication, and a blank configuration without a HIM operator interface.

A major characteristic of the JN configuration is that the drive is specified with no internal dynamic-braking transistor. This distinguishes it from corresponding JA-configured versions when braking hardware is required.

5. Electrical Rating

The 171 A output-current rating is one of the most important characteristics of this drive.

At the 690 VAC class, the drive is intended for large industrial motors and high-power mechanical systems. The normal-duty rating reaches approximately 160 kW, while the heavy-duty rating is approximately 132 kW.

The distinction between Normal Duty and Heavy Duty is important when selecting the drive.

Normal Duty applications generally involve loads where the motor does not experience severe cyclic overload requirements.

Heavy Duty applications normally involve higher torque requirements, more demanding acceleration, frequent load changes, or higher overload demands.

For engineering selection, the actual motor full-load current should always be compared with the drive’s applicable duty rating rather than selecting the drive based only on motor horsepower or kilowatt rating.

---

6. Normal Duty and Heavy Duty Capability

Rating Category	Specification
Model	20G1ANF171JN0NNNNN
Voltage Class	690 VAC
Output Current	171 A
Normal Duty	160 kW
Heavy Duty	132 kW
Frame	Frame 7
Cooling	Forced Air
Phase	Three Phase

The 160 kW Normal Duty rating makes the drive suitable for large centrifugal pumps, large ventilation systems, conveyors, fans, process machinery, and other applications where the operating load is relatively stable.

The 132 kW Heavy Duty rating provides a lower motor-power rating because Heavy Duty operation places greater thermal and electrical demands on the drive.

For applications with significant starting torque, frequent acceleration and deceleration, or high cyclic loading, the Heavy Duty rating should receive particular attention during drive selection.

---

7. Frame 7 Construction

The 20G1ANF171JN0NNNNN uses a Frame 7 power section.

Frame 7 is associated with higher-power PowerFlex 755 configurations and provides a substantially larger power-handling structure than the smaller Frame 6 units.

The larger frame allows the drive to accommodate higher current levels, larger power components, greater cooling requirements, and the physical clearances necessary for high-power electrical equipment.

Because this is a large industrial drive, cabinet layout should provide sufficient space around the equipment for ventilation, service access, wiring, and removal of major components.

---

8. Dimensions and Weight

The physical size and shipping weight of a PowerFlex 755 Frame 7 assembly can vary according to the exact factory configuration, mounting arrangement, accessories, and installation components.

For that reason, the dimensions and weight should be treated as configuration-dependent rather than assuming that every installation has exactly the same mechanical envelope.

Mechanical Parameter	Specification
Model	20G1ANF171JN0NNNNN
Frame	Frame 7
Enclosure	IP20/IP00 Open Type
Cooling	Forced Air
Overall Dimensions	Configuration dependent
Width	Configuration dependent
Height	Configuration dependent
Depth	Configuration dependent
Net Weight	Configuration dependent, kg
Shipping Weight	Higher than net equipment weight
Cabinet Clearance	Required for airflow and maintenance
Installation Orientation	Follow approved drive installation arrangement

For engineering drawings, cabinet fabrication, transportation planning, and replacement projects, the actual dimension drawing associated with the specific drive configuration should be used.

This is particularly important for Frame 7 equipment because cabinet depth, airflow clearance, power wiring, and service access can significantly affect the overall installation space.

---

9. AC Input with Precharge

The 20G1ANF171JN0NNNNN uses an AC input with precharge.

The precharge function helps manage the initial charging of the drive’s internal DC bus capacitors when power is applied.

This is important for high-power drives because the DC bus contains substantial stored energy and the input charging process must be controlled appropriately.

The model does not provide external DC input terminals as part of this standard configuration.

This configuration is therefore primarily intended for conventional AC line-fed drive applications rather than installations where a common DC bus architecture is the main design requirement.

---

10. Dynamic Braking Configuration

One of the most important differences between the JN and JA versions is the dynamic-braking configuration.

For the 20G1ANF171JN0NNNNN, the specified configuration is:

Dynamic Braking: None

This means the JN version does not include the internal dynamic-braking transistor found in the corresponding JA configuration.

For loads that naturally decelerate slowly, such as many centrifugal fans and pumps, this may not be a major limitation.

However, applications involving rapid stopping, high-inertia machinery, hoists, high-speed conveyors, unwinders, centrifuges, or other systems requiring aggressive deceleration may require a different braking arrangement.

The braking requirements should therefore be evaluated during system design rather than simply comparing motor kW ratings.

---

11. Filtered Configuration and CM Jumper

The drive is supplied in a filtered configuration with the CM jumper installed.

This configuration is useful in industrial environments where electrical noise, common-mode effects, and electromagnetic compatibility need to be considered.

Correct grounding, cable routing, motor cable selection, cabinet construction, and shield termination remain important even when the drive includes filtering.

The filter configuration should be coordinated with the facility grounding system and the motor installation.

---

12. Embedded EtherNet/IP Communication

The 20G1ANF171JN0NNNNN includes embedded EtherNet/IP communication.

This allows the drive to participate directly in an industrial Ethernet control architecture without requiring the basic drive to rely entirely on an external communication adapter.

Typical functions can include:

• Drive command and status communication.
• Speed reference transmission.
• Frequency and speed monitoring.
• Current and torque monitoring.
• Fault and alarm information.
• Drive status feedback.
• Parameter access.
• PLC-based control.
• HMI integration.
• Supervisory control.
• Production data collection.
• Diagnostic information exchange.

For large industrial systems, integrated communication can simplify the overall control architecture and reduce the amount of additional communication hardware required.

---

13. No HIM Configuration

The model is specified as Blank (No HIM).

HIM refers to the Human Interface Module normally used for local drive interaction.

A no-HIM configuration is suitable when the drive is intended to be controlled and monitored primarily through a PLC, HMI, SCADA system, or other automation network.

This arrangement can also be useful for centralized control cabinets where operators are not expected to interact directly with every individual drive.

If local keypad operation is required, an appropriate interface solution can be considered separately.

---

14. Product Introduction

The 20G1ANF171JN0NNNNN is designed for high-power industrial motor control where stable speed regulation, controlled acceleration, controlled deceleration, and integration into a plant automation system are required.

The drive combines a high-voltage 690 VAC class with a 171 A output-current capability, making it suitable for substantial motor loads.

Its Frame 7 construction and forced-air cooling system are intended for continuous industrial operation under appropriate environmental and installation conditions.

The embedded EtherNet/IP interface makes the drive particularly suitable for automated production systems where motor commands and feedback need to be exchanged with a central controller.

Because the model uses an open-type IP20/IP00 construction, it is normally installed inside a suitable industrial cabinet or protected electrical enclosure rather than being mounted directly in an exposed outdoor environment.

---

15. Main Product Advantages

15.1 High Power Capability

The 160 kW Normal Duty rating provides substantial motor-control capacity for large industrial equipment.

The 132 kW Heavy Duty rating provides a defined operating class for applications with more demanding load characteristics.

---

15.2 690 VAC High-Voltage Platform

The 690 VAC class is particularly useful for large industrial motor systems.

Compared with lower-voltage systems, the higher operating voltage allows high power levels to be handled with comparatively lower current for the same approximate power level.

This can help with system architecture, conductor sizing, and high-power motor installations.

---

15.3 171 A Output Capability

The 171 A output class makes this model suitable for considerably larger motors than many smaller Frame 6 PowerFlex configurations.

It is appropriate for applications where motor current requirements exceed the practical range of smaller drive models.

---

15.4 Frame 7 High-Power Construction

The Frame 7 design provides a larger mechanical and electrical platform suitable for high-power drive applications.

It is appropriate for large industrial control cabinets and centralized drive systems.

---

15.5 Embedded EtherNet/IP

Integrated EtherNet/IP communication simplifies integration with industrial automation systems.

The drive can be incorporated into a networked architecture for control, monitoring, diagnostics, and data exchange.

---

15.6 Forced-Air Cooling

Forced-air cooling is suitable for high-power industrial drive applications where significant heat must be removed from the power electronics.

Proper cabinet airflow and cooling design are essential to maintain reliable operation.

---

15.7 Integrated Filtering

The filtered configuration provides additional consideration for electromagnetic compatibility and common-mode electrical behavior.

This can be valuable in installations with multiple drives, long motor cables, sensitive instrumentation, or other electronic equipment.

---

15.8 No Internal Dynamic-Braking Transistor

The absence of an internal braking transistor makes the JN configuration distinct from the JA version.

This configuration can be appropriate when the application does not require the internal dynamic-braking function or when braking is handled through a different system architecture.

---

16. Typical Applications

Industrial Pumps

Large water pumps, process pumps, cooling-water pumps, circulation pumps, and other large centrifugal pumping systems can benefit from variable-speed operation.

The drive can regulate pump speed according to process demand rather than operating the motor continuously at full speed.

This can improve process control and reduce unnecessary mechanical operation.

---

Large Fans and Blowers

The drive is well suited to industrial ventilation fans, exhaust systems, cooling towers, combustion-air fans, process blowers, and other large airflow equipment.

Fan applications are often suitable for variable-speed control because airflow requirements can change substantially during operation.

---

Conveyor Systems

Large conveyors used in mining, bulk material handling, manufacturing, warehousing, and processing facilities can require controlled acceleration and speed regulation.

The drive can provide controlled motor operation while allowing the production system to adjust conveyor speed according to process requirements.

---

Material Handling Equipment

High-power material-handling systems can use this type of drive for controlled motor speed and coordinated automation.

Examples include large belt conveyors, transfer systems, feeders, and other continuous material movement equipment.

---

Process Machinery

The drive can be used on mixers, agitators, processing equipment, large rotating machinery, and production systems where motor speed needs to be adjusted according to process conditions.

---

Water and Wastewater Equipment

Large pumping stations, water-treatment systems, aeration equipment, and wastewater pumping systems can require high-power variable-frequency control.

The 690 VAC platform is suitable for large installations where substantial motor power is required.

---

Mining and Bulk Handling

Large material transport and processing equipment often requires high-power drives.

The 171 A rating and Frame 7 architecture make this model suitable for selected high-power mining and bulk-material applications where environmental and cabinet requirements are properly addressed.

18. Installation Considerations

The 20G1ANF171JN0NNNNN is an open-type industrial drive and should normally be installed inside an appropriate electrical cabinet, control enclosure, MCC, or other protected installation.

The cabinet must provide adequate airflow around the drive.

Because this is a high-power forced-air-cooled drive, heat generated during operation must be removed effectively.

Important installation considerations include:

• Adequate cabinet ventilation.
• Correct incoming power protection.
• Proper grounding.
• Correct motor cable selection.
• Appropriate cable routing.
• Adequate clearance around the drive.
• Correct control wiring.
• Proper EtherNet/IP network installation.
• Protection from excessive dust and moisture.
• Appropriate ambient temperature management.
• Service access for cooling fans and power components.

---

19. Maintenance Considerations

Routine maintenance should focus on airflow, electrical connections, cooling components, and the overall installation environment.

The cooling system should be kept clean because dust accumulation can restrict airflow and increase operating temperature.

Electrical connections should be inspected according to the applicable maintenance schedule.

The drive cabinet should also be inspected for excessive dust, moisture, corrosion, loose wiring, abnormal noise, or signs of overheating.

Network communication should be monitored where the drive is integrated into a PLC or supervisory control system.

Fault history and diagnostic information can also be useful for identifying developing problems before they become major production interruptions.

32. Overall Product Summary

The Allen-Bradley 20G1ANF171JN0NNNNN is a high-power PowerFlex 755 AC drive designed for large industrial motor-control applications.

Its combination of 690 VAC three-phase operation, 171 A output current, 160 kW Normal Duty capacity, 132 kW Heavy Duty capacity, Frame 7 construction, forced-air cooling, integrated filtering, and embedded EtherNet/IP communication makes it suitable for large automated industrial systems.

The JN configuration is particularly important because it is specified with no dynamic-braking transistor. Therefore, braking requirements should be evaluated carefully when applying the drive to high-inertia machinery or systems requiring rapid controlled stopping.

Its open-type IP20/IP00 construction means that the drive is normally integrated into a suitable electrical cabinet or protected industrial enclosure.

For centralized automation systems, the blank/no-HIM configuration can be advantageous because control and monitoring can be handled through EtherNet/IP, PLC systems, HMIs, or supervisory control platforms.

The most closely related models are the 20G1ANF142JN0NNNNN, 20G1ANF212JN0NNNNN, 20G1ANF263JN0NNNNN, and the corresponding 20G1ANF171JA0NNNNN configuration.

When selecting among these models, the most important factors are the facility voltage, motor full-load current, Normal Duty or Heavy Duty classification, required braking performance, cabinet arrangement, cooling requirements, and automation-network architecture.

For a 690 VAC high-power installation where the motor current is around the 171 A class and the application does not require the internal dynamic-braking transistor, 20G1ANF171JN0NNNNN represents a high-capacity Frame 7 PowerFlex 755 configuration intended for demanding industrial motor-control systems.
