Allen-Bradley 20G1ANF023AN0NNNNN PowerFlex 755 AC Drive

1. Product Overview

The Allen-Bradley 20G1ANF023AN0NNNNN is a PowerFlex 755 AC drive designed for three-phase industrial motor-control applications using a 690 VAC power system.

This model has a 23 A Normal Duty output rating and an 18.5 kW Normal Duty rating, while its Heavy Duty rating is 20 A and 15 kW. It occupies an important position in the 690 VAC section of the PowerFlex 755 family, sitting between the 20 A and 30 A drive classes.

The drive uses a Frame 6 mechanical platform and forced-air cooling. Its open-type IP20/IP00 construction is intended for installation in a suitable electrical cabinet or enclosure.

The model is configured with AC input with precharge and no external DC terminals. It also incorporates embedded EtherNet/IP communication, providing a convenient way to integrate the drive into an industrial automation network.

An important characteristic of this particular catalog number is the AN0 configuration. Compared with the corresponding JA0 version, the AN0 configuration has the CM jumper removed and does not include an internal dynamic-braking transistor.

This distinction is important when selecting a replacement because two drives with the same voltage, current, power, and frame ratings may still have different factory configurations.

5. Normal Duty Rating

The Normal Duty rating of the 20G1ANF023AN0NNNNN is 23 A continuous and 18.5 kW.

The drive can provide approximately 25.3 A for one minute and 34.5 A for three seconds under the specified Normal Duty rating conditions.

This makes the model suitable for industrial loads that normally operate within the 23 A continuous-current range while occasionally experiencing short-term increases in current.

Typical examples include pumps, fans, blowers, conveyors, process equipment, and other machinery with moderate overload requirements.

The actual motor nameplate current should always be checked when selecting the drive.

---

6. Heavy Duty Rating

For Heavy Duty operation, the drive is rated at 20 A continuous and 15 kW.

Its Heavy Duty short-term current capability is approximately 30 A for one minute and 36 A for three seconds.

The Heavy Duty rating is relevant to machines with higher starting torque, more demanding acceleration, or temporary overload conditions.

This gives the same drive platform two useful application points: 18.5 kW under Normal Duty and 15 kW under Heavy Duty.

For applications with high inertia or frequent acceleration and deceleration, the Heavy Duty rating should be evaluated using the actual load profile.

---

7. 690 VAC Three-Phase Voltage Class

The 20G1ANF023AN0NNNNN is designed for a 690 VAC three-phase system.

This voltage class is commonly associated with higher-voltage industrial motor systems.

It can be considered for industrial pumping stations, process plants, production equipment, ventilation systems, conveyors, material-handling systems, and other applications where 690 VAC motors are used.

The incoming supply voltage and motor nameplate voltage should be compatible with the drive’s voltage class.

A lower-voltage motor-control system should not be treated as interchangeable simply because the output current appears suitable.

---

8. Frame 6 Mechanical Design

The drive uses a Frame 6 mechanical design.

Frame 6 is a substantial industrial drive platform and provides a common physical format across several nearby current ratings in the 690 VAC PowerFlex 755 range.

The approximate dimensions are:

665.5 mm × 308.0 mm × 346.4 mm

The approximate weight is:

38.6 kg

These figures are useful for preliminary cabinet planning.

The actual installation should allow additional space for cable routing, cooling airflow, maintenance access, mounting arrangements, and associated electrical equipment.

---

9. Forced-Air Cooling

The drive uses forced-air cooling to manage heat generated by the power electronics.

This cooling arrangement is appropriate for the drive’s power class but requires a suitable installation environment.

The cabinet should be designed so that hot air does not accumulate around the drive.

Adequate airflow should be maintained throughout the operating life of the equipment.

Dust, oil mist, fibers, and other industrial contaminants can gradually affect cooling performance, so the surrounding environment should be considered when designing the enclosure.

---

10. Embedded EtherNet/IP Communication

The 20G1ANF023AN0NNNNN includes embedded EtherNet/IP capability.

This allows the drive to be integrated into an industrial Ethernet-based control system.

Depending on the automation architecture, the drive can exchange operating commands and status information with a compatible controller.

Commonly useful information includes motor speed, output current, drive status, alarms, fault information, and other operating data.

This makes the PowerFlex 755 more than a standalone frequency converter. It can function as an integrated motor-control device within a larger automation system.

---

11. AC Input With Precharge

The drive uses an AC input with precharge.

Precharge is part of the input-power architecture and controls the initial charging of the drive’s internal DC bus when the drive is energized.

The model has no external DC terminals.

Therefore, the installation should be designed around its specified AC-input configuration rather than assuming that external DC-bus connections are available.

---

12. Filtered Configuration

The model uses a filtered configuration.

Electromagnetic compatibility is an important consideration in VFD installations because the high-frequency switching operation of the power electronics can generate electrical noise.

The drive’s filtering configuration can help support an appropriate EMC installation strategy.

However, the complete installation still matters.

Motor cable construction, grounding, shielding, cable length, cabinet layout, signal wiring, and separation between power and control wiring can all affect the final EMC performance of the system.

---

13. CM Jumper Removed

One of the most important configuration details of 20G1ANF023AN0NNNNN is the CM jumper removed arrangement.

This differentiates the model from the corresponding configuration with the CM jumper installed.

The common-mode capacitor configuration can affect the electrical relationship between the drive, motor, and grounding system.

For replacement work, this detail should be matched to the intended installation.

A drive with the same current and voltage rating but a different CM jumper configuration should not automatically be treated as an identical replacement.

---

14. No Internal Dynamic-Braking Transistor

The model does not include an internal dynamic-braking transistor.

This characteristic is represented by the N0 portion of the configuration.

Dynamic braking becomes important when a motor must decelerate rapidly or when a high-inertia load returns significant energy to the drive.

For applications with gradual acceleration and deceleration, this may not present a major concern.

For high-inertia machinery or applications requiring frequent rapid stopping, the braking system should be evaluated separately.

---

15. Product Introduction

The PowerFlex 755 is an industrial AC drive platform designed for applications requiring adjustable motor speed, configurable motor control, automation-system integration, and a broad range of industrial operating capabilities.

The 20G1ANF023AN0NNNNN occupies the 23 A position in the 690 VAC PowerFlex 755 range.

Its 18.5 kW Normal Duty rating makes it suitable for medium-power industrial motors.

Its 15 kW Heavy Duty rating provides a separate operating point for applications with greater overload requirements.

This makes the model useful across a broad range of industrial machines where motor speed must be controlled rather than operated continuously at fixed line frequency.

---

16. Pump Applications

Pumping systems are one of the most common applications for variable-frequency drives.

The drive can adjust motor speed according to process demand.

This can be useful for:

• Water circulation systems
• Industrial cooling systems
• Process-fluid transfer
• Water-treatment equipment
• Industrial pumping stations
• Utility pumping systems
• Process pumps

A variable-speed motor can provide more flexibility than a fixed-speed motor when the required flow changes.

The 690 VAC class also makes this model suitable for higher-voltage industrial pumping equipment.

---

17. Fan and Blower Applications

Fans and blowers frequently operate under changing airflow requirements.

A variable-frequency drive can adjust motor speed according to the required airflow rather than operating continuously at maximum speed.

Potential applications include:

• Industrial ventilation
• Exhaust systems
• Cooling fans
• Process blowers
• Air-handling systems
• Industrial ventilation equipment

The 18.5 kW Normal Duty rating provides a useful capacity for medium-power industrial fan and blower motors, subject to the actual motor current.

---

18. Conveyor Applications

Conveyor systems benefit from controlled acceleration and adjustable operating speed.

The drive can provide a gradual acceleration profile rather than simply connecting the motor directly to full-frequency power.

This can help provide smoother machine operation.

Conveyors can also benefit from adjustable speed when production rates change or when different products require different handling speeds.

The embedded Ethernet communication capability is useful when conveyors need to be integrated with a larger production-control system.

---

19. Compressor Applications

Compressors can have demanding acceleration characteristics and can require controlled motor operation.

The drive can provide variable-speed control where the compressor design supports VFD operation.

Potential applications include:

• Industrial air compressors
• Process compressors
• Cooling-related equipment
• Utility compressors
• Industrial pressure systems

The actual compressor load curve should be evaluated before final drive selection.

---

20. Mixer and Agitator Applications

Mixers and agitators often operate at different speeds during different stages of a production process.

The drive allows the motor to accelerate gradually and operate at controlled speeds.

This can be useful in:

• Process mixing
• Chemical processing
• Wastewater treatment
• Material blending
• Food processing
• Industrial agitation

For heavy or highly viscous materials, the starting torque requirement should be checked carefully.

---

21. Material-Handling Applications

Material-handling machinery can benefit from adjustable motor speed and controlled acceleration.

Potential applications include:

• Conveyors
• Feeders
• Transfer systems
• Production-line equipment
• Material-processing machinery
• Packaging systems

The embedded EtherNet/IP interface can also be used to integrate drive operation with other automated equipment.

---

22. Process Machinery Applications

The drive can be considered for a wide variety of process machinery.

Typical applications include:

• Pumps
• Fans
• Blowers
• Mixers
• Agitators
• Conveyors
• Feeders
• Process equipment
• Utility equipment
• Production machinery

The exact selection should be based on the actual motor current, voltage, load characteristics, acceleration requirements, environmental conditions, and required braking performance.

---

23. Main Product Advantages

23.1 23 A Normal Duty Output

The 23 A output rating gives the model a useful position between the smaller 20 A and larger 30 A drives in the same 690 VAC family.

This can be valuable when a motor’s current requirement falls above the 20 A class but does not require the larger 30 A drive.

---

23.2 18.5 kW Normal Duty Rating

The 18.5 kW Normal Duty rating provides substantial capacity for industrial motor applications.

It is suitable for many medium-power machines where the motor operates under normal duty conditions.

---

23.3 15 kW Heavy Duty Rating

The 15 kW Heavy Duty rating provides an alternative operating point for applications with more demanding load conditions.

This makes the drive flexible for applications where the same hardware may be used under different duty classifications.

---

23.4 690 VAC Industrial Voltage

The 690 VAC rating makes the drive suitable for higher-voltage industrial motor systems.

This is particularly relevant in large facilities and process installations where 690 VAC motors are part of the plant electrical architecture.

---

23.5 Embedded EtherNet/IP

Integrated industrial Ethernet communication makes it easier to incorporate the drive into an automation system.

This can simplify monitoring, diagnostics, command functions, and system-level coordination.

---

23.6 Frame 6 Construction

Frame 6 provides a substantial industrial mechanical platform.

It also gives several neighboring current ratings a common physical format, which can simplify mechanical planning when multiple drives are installed in the same system.

---

23.7 Filtered Configuration

The filtered configuration provides an appropriate foundation for industrial EMC planning.

The overall result still depends on proper system installation.

---

23.8 CM Jumper Removed

The removed-jumper configuration provides a clearly defined common-mode arrangement.

This is particularly important for applications where the grounding and motor system have been designed around a specific CM configuration.

---

23.9 No Internal Dynamic-Braking Transistor

The absence of the internal dynamic-braking transistor provides a distinct configuration for applications where an internal braking transistor is not required.

For applications with braking requirements, the complete deceleration and energy-management strategy should be considered separately.

---

The 20 A and 23 A models are particularly close in electrical capacity.

The 23 A version provides additional current capacity above the 20 A class while retaining the same general Frame 6 physical platform.

The 30 A model provides another step upward when the motor requires greater continuous current.

---

25. Five Related Models With Higher Capacity

For larger motors, the 690 VAC PowerFlex 755 family extends into higher current ranges.

Model	Normal Duty	Heavy Duty	Frame	Approx. Dimensions	Approx. Weight
20G1ANF030JN0NNNNN	30 A / 22 kW	23 A / 18.5 kW	6	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6 kg

20G1ANF046JN0NNNNN	46 A / 37 kW	34 A / 30 kW	6	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6 kg
20G1ANF061JN0NNNNN	61 A / 55 kW	50 A / 45 kW	6	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6 kg
20G1ANF082JN0NNNNN	82 A / 75 kW	61 A / 55 kW	6	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6 kg

These models provide a practical progression for larger 690 VAC motors.

As the current rating increases, the electrical installation must also be reviewed for appropriate cable sizing, protection, thermal management, and cabinet design.

---

26. Five Related Configuration Models

For applications where the basic electrical rating remains 23 A but configuration requirements differ, the following catalog numbers are useful for comparison.

Model	Voltage	Normal Duty	Heavy Duty	CM Jumper	Dynamic Braking	Frame	Approx. Dimensions	Approx. Weight
20G1ANF023AA0NNNNN	690 VAC	23 A / 18.5 kW	20 A / 15 kW	Removed	Internal DB Transistor	6	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6 kg
20G1ANF023AN0NNNNN	690 VAC	23 A / 18.5 kW	20 A / 15 kW	Removed	None	6	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6 kg
20G1ANF023JA0NNNNN	690 VAC	23 A / 18.5 kW	20 A / 15 kW	Installed	Internal DB Transistor	6	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6 kg

20G1AGF023AN0NNNNN	690 VAC	23 A / 18.5 kW	20 A / 15 kW	Removed	None	6	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6 kg

This table illustrates why the final configuration characters matter.

The 20G1ANF023AN0NNNNN and 20G1ANF023JN0NNNNN have the same basic 23 A, 690 VAC electrical rating, but their CM jumper configurations are different.

The AA0 and JA0 versions add an internal dynamic-braking transistor.

The model requested here is specifically the AN0 configuration, meaning CM jumper removed and no internal dynamic-braking transistor.

The 23 A model provides a higher current and power rating.

The CM jumper configuration is also different between the two catalog numbers shown above, which demonstrates why the exact catalog number should be checked during replacement.

---

29. Comparison With the 20G1ANF023JN0NNNNN

The 20G1ANF023JN0NNNNN is particularly close to the requested model because the voltage, current, power, frame, and general drive platform are the same.

Parameter	20G1ANF023AN0NNNNN	20G1ANF023JN0NNNNN
Voltage	690 VAC	690 VAC
Normal Duty Current	23 A	23 A

Approx. Dimensions	665.5 × 308 × 346.4 mm	665.5 × 308 × 346.4 mm
Approx. Weight	38.6 kg	38.6 kg

This is an important comparison for replacement work.

The two drives have the same basic electrical ratings, but the CM jumper configuration differs.

Therefore, the exact catalog number should be checked before treating one as a direct replacement for the other.

---

30. Comparison With the 20G1ANF023JA0NNNNN

The 20G1ANF023JA0NNNNN has the same basic 23 A, 690 VAC electrical rating but includes an internal dynamic-braking transistor and has the CM jumper installed.

Parameter	20G1ANF023AN0NNNNN	20G1ANF023JA0NNNNN
Voltage	690 VAC	690 VAC
Normal Duty Current	23 A	23 A
Normal Duty Power	18.5 kW	18.5 kW
Heavy Duty Current	20 A	20 A
Heavy Duty Power	15 kW	15 kW

Approx. Dimensions	665.5 × 308 × 346.4 mm	665.5 × 308 × 346.4 mm
Approx. Weight	38.6 kg	38.6 kg

This comparison shows that the catalog-number suffix is not simply an ordering code.

It can identify meaningful differences in the drive’s electrical configuration.

---

31. Pump-System Advantages

For pump applications, the drive provides adjustable motor speed and network integration.

The 18.5 kW Normal Duty capacity provides a useful operating point for medium-power industrial pumps.

The 15 kW Heavy Duty rating gives the same hardware a lower power point when the load requires the Heavy Duty classification.

The 690 VAC rating also makes it appropriate for higher-voltage industrial pump systems.

---

32. Fan and Blower Advantages

Fan and blower applications can benefit from variable-speed operation.

The motor can be adjusted according to ventilation or process requirements instead of operating continuously at a fixed speed.

The 23 A output capacity gives the drive enough current capability for a range of medium-power industrial fans and blowers, subject to the motor’s actual rated current.

---

33. Conveyor Advantages

The drive can provide controlled acceleration and variable operating speed for conveyors.

This can be useful when the conveyor needs to synchronize with other production machinery.

Network communication can also allow operating status and faults to be monitored centrally.

For high-inertia conveyors, however, the deceleration and braking requirements should be examined carefully because this particular model does not contain an internal dynamic-braking transistor.

---

34. Compressor Advantages

For compatible compressor designs, variable-speed operation can provide greater flexibility than fixed-speed motor operation.

The drive can control acceleration and operating speed while communicating important operating information to the automation system.

The actual compressor load characteristics should be evaluated before final application selection.

---

35. Process Equipment Advantages

The drive is suitable for process equipment where motor speed needs to change according to production requirements.

Examples include:

• Mixing equipment
• Agitators
• Pumps
• Fans
• Blowers
• Conveyors
• Feeders
• Industrial processing machines

The ability to communicate over Ethernet can also simplify integration with a broader process-control architecture.

---

36. Cabinet Installation Considerations

Because the drive is an IP20/IP00 open-type product, it should be installed in a suitable electrical cabinet or enclosure.

The cabinet should provide enough space for the approximately 665.5 × 308.0 × 346.4 mm drive.

The approximately 38.6 kg weight should also be considered when designing the mounting structure.

Additional space should be reserved for:

• Power cables
• Motor cables
• Control wiring
• Ethernet cables
• Grounding connections
• Cooling airflow
• Service access
• Maintenance work

A compact cabinet should not sacrifice the airflow required for proper thermal management.

---

37. Motor Selection Considerations

The motor should be evaluated using actual nameplate information.

Important parameters include:

• Rated voltage
• Rated current
• Rated power
• Rated frequency
• Rated speed
• Starting torque
• Continuous torque
• Overload requirements
• Acceleration time
• Deceleration time
• Mechanical inertia

The 23 A Normal Duty rating should not be interpreted as meaning that every 18.5 kW motor is automatically suitable.

Motor voltage and actual motor current remain important selection criteria.

---

38. Dynamic-Braking Considerations

The 20G1ANF023AN0NNNNN does not contain an internal dynamic-braking transistor.

This should be considered for machines requiring rapid stopping.

Potentially demanding applications include:

• High-inertia conveyors
• Large rotating equipment
• Centrifugal machinery
• Hoisting-related machinery
• Rapid-cycle production equipment
• Machines with frequent acceleration and deceleration

If the application does not require rapid deceleration, the absence of the internal braking transistor may be less significant.

---

39. EMC and Grounding Considerations

The AN0 configuration has the CM jumper removed.

This configuration should be considered together with the grounding arrangement, motor cable design, and overall electrical system.

Good installation practice remains important.

Power and control wiring should be routed appropriately, grounding should be properly established, and motor cable selection should be suitable for variable-frequency-drive operation.

The drive’s filtering configuration is only one part of the complete EMC solution.

---

40. Maintenance Considerations

Maintenance should include inspection of the drive’s cooling system and surrounding cabinet environment.

The forced-air cooling path should remain clear.

The cabinet should be kept reasonably clean and free from excessive dust, oil mist, and other contamination.

Electrical connections should be inspected according to the maintenance procedures established for the installation.

Network connections should also be checked in systems where the drive is integrated through EtherNet/IP.

Monitoring fault history can provide useful information when investigating intermittent problems.

41. Troubleshooting Considerations

A structured troubleshooting process can help identify whether a problem is caused by the drive, motor, power system, communication system, or mechanical equipment.

Incoming Power

Check three-phase supply voltage, protection devices, connections, and power quality.

Motor

Check motor wiring, insulation, nameplate information, current, and mechanical load.

Drive

Check drive status, alarms, fault history, cooling condition, and configuration.

Communication

Check Ethernet connections, network configuration, controller communication, and drive status.

Mechanical Equipment

Check bearings, couplings, gearboxes, pumps, fans, conveyors, and other mechanical components.

A drive fault does not necessarily mean that the drive itself is defective.

48. Why the Exact Model Number Matters

The catalog number 20G1ANF023AN0NNNNN should be treated as a complete technical identification.

The 23 A current class identifies the drive’s output capacity, while the voltage designation identifies the 690 VAC system.

The A configuration indicates the CM jumper-removed arrangement.

The N0 configuration identifies the version without an internal dynamic-braking transistor.

These details can become especially important when purchasing replacement equipment.

A replacement that matches the current and voltage rating but has a different CM or braking configuration may not provide the same electrical arrangement as the original drive.

49. Spare-Parts Planning

For industrial plants, maintaining accurate spare-drive information can simplify maintenance.

A spare for the 20G1ANF023AN0NNNNN should be checked for:

• Exact catalog number
• Voltage class
• Current rating
• Normal Duty rating
• Heavy Duty rating
• Frame size
• Filtering configuration
• CM jumper configuration
• Dynamic-braking configuration
• Communication requirements
• Physical dimensions
• Weight
• Motor requirements

This information helps prevent confusion between closely related PowerFlex 755 models.

51. Final Product Description

The Allen-Bradley 20G1ANF023AN0NNNNN PowerFlex 755 AC Drive is a 690 VAC three-phase industrial variable-frequency drive designed for medium-power motor-control applications.

With a 23 A Normal Duty output and 18.5 kW Normal Duty rating, it provides a useful solution for industrial motors operating under normal load conditions.

Under Heavy Duty operation, the drive provides a 20 A continuous output rating and 15 kW Heavy Duty power rating.

The drive’s Normal Duty short-term ratings are approximately 25.3 A for one minute and 34.5 A for three seconds, while the Heavy Duty ratings provide approximately 30 A for one minute and 36 A for three seconds.

The Frame 6 mechanical design uses forced-air cooling and has approximate dimensions of 665.5 × 308.0 × 346.4 mm, with an approximate weight of 38.6 kg.

The model uses AC input with precharge and does not provide external DC terminals.

Its filtered configuration and CM jumper removed arrangement distinguish it from related PowerFlex 755 catalog numbers with the jumper installed.

The model also does not include an internal dynamic-braking transistor. This is an important consideration for applications involving high-inertia loads or rapid deceleration.

Embedded EtherNet/IP provides a convenient communication interface for integrating the drive into industrial automation systems.

The model can be applied to pumps, fans, blowers, conveyors, compressors, mixers, agitators, material-handling equipment, and other process machinery where variable-speed AC motor control is required.

One of the main practical strengths of this model is its position within the 690 VAC PowerFlex 755 range. The 20 A version provides a lower capacity option, while the 30 A, 34 A, 46 A, and larger models provide progressively greater motor capacity.

The 20G1ANF023AN0NNNNN is therefore a useful selection for applications where a 690 VAC motor requires more capacity than the 20 A class but does not need the larger 30 A class.

For replacement purposes, the complete catalog number should always be checked. In particular, the difference between AN0, JN0, AA0, and JA0 configurations can affect the CM jumper and dynamic-braking arrangement even when the basic voltage, current, power, and frame ratings are similar.

Overall, the 20G1ANF023AN0NNNNN combines 690 VAC three-phase operation, 23 A Normal Duty capacity, 18.5 kW Normal Duty power, 20 A Heavy Duty capability, 15 kW Heavy Duty power, Frame 6 construction, forced-air cooling, embedded EtherNet/IP communication, filtered configuration, and a CM-jumper-removed/no-internal-DB configuration into a substantial industrial motor-control platform.
