4. Electrical Specification

The 20G1ANB130JA0NNNNN operates from a three-phase 208…240 VAC input supply. The voltage class makes this model particularly suitable for industrial facilities and machine systems using 240 V-class three-phase distribution.

The drive converts the incoming fixed-frequency AC supply into a controlled variable-frequency output for the connected motor. By adjusting output frequency and voltage, the drive can regulate motor speed and provide controlled starting and stopping.

The published configuration specifies 130 A Normal Duty current and 104 A Heavy Duty current. The Normal Duty rating corresponds to 50 HP, or approximately 37 kW, while the Heavy Duty rating corresponds to 45 HP, or approximately 33.6 kW.

---

5. Normal Duty Rating

The Normal Duty rating is 130 A continuous and is associated with a 50 HP motor rating in the 208…240 VAC class.

Normal Duty operation is generally used where the motor load does not require the higher overload capability associated with demanding constant-torque machinery. Typical examples include centrifugal pumps, centrifugal fans, blowers, and other loads where the torque requirement generally follows the operating speed.

For these applications, the 20G1ANB130JA0NNNNN provides a combination of speed control, acceleration control, deceleration control, motor protection, and network connectivity.

---

6. Heavy Duty Rating

The Heavy Duty rating is 104 A continuous and corresponds to a 45 HP rating.

Heavy Duty operation is intended for applications where the motor may experience higher starting torque, greater load variation, or more demanding acceleration requirements.

The distinction between Normal Duty and Heavy Duty is important when selecting a drive. A motor should not simply be matched to the highest horsepower number shown on a drive without considering the actual load profile, overload requirements, acceleration time, operating speed, ambient temperature, and application duty cycle.

For conveyors, mixers, positive-displacement equipment, loaded machinery, and other higher-torque applications, the Heavy Duty rating should be considered during system sizing.

---

7. 208…240 VAC Three-Phase Operation

The 208…240 VAC input range places this drive within the lower-voltage PowerFlex 755 product group.

Three-phase input provides the appropriate electrical architecture for industrial motor applications and allows the drive to deliver its specified output ratings when correctly supplied and installed.

The input power system should be checked before installation for:

• Line voltage.
• Phase configuration.
• Available fault current.
• Grounding arrangement.
• Protective device coordination.
• Cable size.
• Disconnect requirements.
• Panel ventilation.
• Local electrical requirements.

The drive should be selected based on the actual motor nameplate voltage and current rather than horsepower alone.

---

8. Frame 6 Construction

The 20G1ANB130JA0NNNNN uses Frame 6 construction.

Frame size determines much more than physical dimensions. It also affects cooling arrangement, mounting requirements, power terminals, cable routing, ventilation clearance, and service access.

The Frame 6 package provides a practical balance between current capacity and cabinet space for medium-power industrial drive systems.

The published dimensions are approximately 665.5 mm × 308 mm × 346.4 mm, with a weight of approximately 37 kg.

---

9. Mechanical Dimensions and Weight

Mechanical Parameter	Specification
Model	20G1ANB130JA0NNNNN
Frame	Frame 6
Height	Approximately 665.5 mm
Width	Approximately 308 mm
Depth	Approximately 346.4 mm
Approximate Weight	37 kg
Height	Approximately 26.20 in
Width	Approximately 12.13 in
Depth	Approximately 13.64 in
Weight	Approximately 82 lb
Mounting Orientation	Vertical
Enclosure	IP20/IP00 Open Type
Cooling	Forced Air
Installation	Panel / Wall Mount

The dimensions and weight should be included in cabinet layout, transportation, installation, lifting, and maintenance planning.

A 37 kg drive should be handled with appropriate lifting and installation procedures, especially when it is being mounted into a high-level panel or equipment enclosure.

---

10. IP20/IP00 Open-Type Construction

The drive uses an IP20/IP00 and NEMA/UL Open Type configuration.

This type of enclosure is intended for installation within a suitable protected electrical environment rather than direct exposure to dust, water, oil mist, washdown spray, or other harsh environmental conditions.

When the drive is installed in a control cabinet, the cabinet should provide suitable environmental protection and maintain adequate airflow around the drive.

The open-type design can be advantageous when the drive is integrated into a larger industrial electrical enclosure because the enclosure can be designed around the complete control system.

---

11. Air-Cooled Design

The 20G1ANB130JA0NNNNN uses forced-air cooling.

The cooling system removes heat generated by the power conversion section during operation. Proper airflow is therefore important for maintaining the drive’s operating temperature.

Panel designers should provide adequate clearance around the drive and avoid positioning heat-producing equipment directly beneath or immediately beside the drive intake area.

Ventilation should also take into account:

• Ambient temperature.
• Cabinet temperature.
• Heat generated by other equipment.
• Fan airflow.
• Filter condition.
• Cabinet ventilation method.
• Altitude.
• Continuous operating load.

A clean cooling path helps maintain stable operation and reduces thermal stress on power components.

---

12. AC Input with Precharge

The catalog configuration specifies AC input with precharge and no DC terminals.

The precharge arrangement limits the initial charging current associated with the drive’s DC bus when power is applied.

This is an important part of the drive’s power-conversion architecture and should be considered when designing the upstream disconnect, protection, and control system.

The absence of DC terminals means the drive should be treated as an AC-input configuration rather than a configuration intended for direct external DC-bus connection.

---

13. Filtering and CM Jumper

This specific model is configured as filtered, with the CM jumper installed.

The filtering arrangement is intended to help manage conducted electrical noise and electromagnetic compatibility within the intended installation environment.

The CM jumper configuration should be considered together with the facility grounding system and the motor-cable installation.

For industrial installations, correct grounding and bonding are just as important as the drive’s internal filtering configuration.

---

14. Dynamic Braking Transistor

The catalog configuration specifies a DB transistor.

A dynamic braking transistor allows an appropriate external braking resistor arrangement to be used when the application requires controlled dissipation of regenerative energy.

This is useful for applications with frequent deceleration, rapid stopping, high-inertia loads, or loads that can drive the motor during deceleration.

Typical applications where dynamic braking may be useful include:

• Conveyors.
• Hoists and lifting machinery.
• Centrifuges.
• High-inertia fans.
• Material-handling systems.
• Machine tools.
• Rapid-cycle machinery.

The braking resistor itself must be selected according to the actual regenerated energy, braking torque, duty cycle, and required stopping time.

---

15. Embedded EtherNet/IP

Embedded EtherNet/IP is included in the 20G1ANB130JA0NNNNN configuration.

This provides a direct network connection between the drive and an industrial control system.

Network communication can be used for:

• Start and stop commands.
• Speed reference.
• Torque reference where applicable.
• Drive status.
• Fault information.
• Warning information.
• Output frequency.
• Output current.
• Motor feedback values.
• Parameter monitoring.
• Diagnostic information.

Using network control can reduce the amount of hardwired control wiring required between the drive and the main automation controller.

---

16. Motor Control Capability

The PowerFlex 755 platform supports multiple motor-control methods.

Depending on the motor and application configuration, control can be based on:

• Volts per Hertz.
• Sensorless vector control.
• Flux vector control.
• Encoder-based control where appropriate.

The selection of the control method should be based on the motor type, required low-speed torque, speed regulation requirements, feedback arrangement, and application dynamics.

For a standard centrifugal pump or fan, a simpler control mode may be adequate.

For a conveyor, extruder, mixer, or other demanding load, vector-based control may provide more useful torque and speed characteristics.

---

17. Product Introduction

The 20G1ANB130JA0NNNNN is intended for industrial motor-control systems where a fixed-speed motor needs to operate at variable speed.

Instead of running a motor continuously at full line frequency and controlling the process through mechanical throttling, dampers, valves, or other methods, a variable-frequency drive can adjust motor speed directly.

This allows the motor to operate closer to the speed actually required by the process.

In pump and fan applications, speed reduction can significantly change the operating point of the equipment. In conveyors, speed can be matched to material flow. In process machinery, controlled acceleration and deceleration can reduce mechanical shock.

The drive therefore acts as both a motor power converter and a control element within the machine or process.

---

18. Main Product Advantages

18.1 Wide Industrial Application Range

The 20G1ANB130JA0NNNNN can be applied to many types of three-phase AC motor loads.

Its 130 A Normal Duty rating provides a substantial current capacity for medium-power machinery.

---

18.2 Integrated Network Communication

Embedded EtherNet/IP reduces the need for separate communication hardware and allows the drive to become part of a networked automation architecture.

This is useful when multiple drives need to be monitored or controlled from a central automation system.

---

18.3 Dynamic Braking Capability

The internal DB transistor provides a convenient architecture for applications requiring additional braking capability.

This is particularly useful when stopping time is important or when the motor and load have substantial stored kinetic energy.

---

18.4 Controlled Acceleration and Deceleration

The drive allows the motor to accelerate and decelerate according to programmed ramps.

This can reduce mechanical shock compared with direct-on-line starting.

For conveyors and rotating machinery, controlled acceleration can also reduce belt tension changes, coupling stress, gearbox shock, and product movement.

---

18.5 Adjustable Motor Speed

Motor speed can be adjusted according to process requirements.

This is useful when the machine does not need to operate continuously at full speed.

---

18.6 Compact Frame 6 Design

The Frame 6 construction provides a substantial current rating in a relatively compact industrial drive package.

The approximate 665.5 × 308 × 346.4 mm dimensions make cabinet planning straightforward when adequate clearances are provided.

---

18.7 Practical Panel Integration

The open-type IP20/IP00 construction allows the drive to be installed inside a suitable electrical enclosure.

This makes it practical to combine the drive with:

• Circuit protection.
• Disconnects.
• PLC equipment.
• I/O modules.
• Contactors.
• Terminal blocks.
• Network switches.
• Safety equipment.
• Motor protection equipment.

---

19. Pump Applications

Typical examples include:

• Water transfer pumps.
• Industrial circulation pumps.
• Cooling-water pumps.
• Process pumps.
• Booster pumps.
• HVAC pumping systems.
• Water-treatment equipment.

Pump systems often benefit from variable-speed operation because the pump does not necessarily need to operate at maximum speed at all times.

The drive can regulate motor speed to match changing process demand.

---

20. Fan and Blower Applications

Fans and blowers are another common variable-speed-drive application.

Examples include:

• Industrial ventilation.
• Exhaust fans.
• Air-handling equipment.
• Process ventilation.
• Cooling systems.
• Dust-collection systems.
• Combustion-air systems.
• Industrial blowers.

The drive can allow fan speed to be adjusted according to airflow requirements instead of operating continuously at full speed.

---

21. Conveyor Applications

The 20G1ANB130JA0NNNNN can be applied to conveyor systems where speed control and controlled acceleration are required.

Typical applications include:

• Belt conveyors.
• Roller conveyors.
• Material-handling conveyors.
• Packaging conveyors.
• Assembly conveyors.
• Warehouse conveyors.
• Bulk-material conveyors.

Controlled acceleration can reduce sudden mechanical loading on belts, couplings, gearboxes, and driven components.

Network communication can also allow conveyor status and speed information to be exchanged with the main control system.

---

22. Compressor Applications

Variable-speed control can be useful for compressors where process demand changes during operation.

The drive can provide:

• Controlled starting.
• Adjustable operating speed.
• Ramp control.
• Fault monitoring.
• Network communication.
• Motor protection functions.

The actual suitability depends on the compressor type, motor characteristics, required torque curve, minimum operating speed, and process requirements.

---

23. Mixer and Agitator Applications

Mixers and agitators often require controlled acceleration and variable operating speed.

The drive can help control:

• Starting torque.
• Acceleration time.
• Operating speed.
• Deceleration.
• Repeated start/stop cycles.

For high-inertia mixers, the braking and overload requirements should be carefully considered when sizing the drive.

---

24. Material-Handling Applications

The drive can be used in material-handling machinery where motor speed must be adjusted according to production requirements.

Examples include:

• Feed systems.
• Transfer equipment.
• Packaging machinery.
• Conveyor lines.
• Sorting equipment.
• Production machinery.
• Bulk-material systems.

The combination of variable speed, programmable acceleration, braking capability, and network communication is useful in coordinated material-handling systems.

---

25. Industrial Process Applications

The 20G1ANB130JA0NNNNN can also be used as a general-purpose industrial motor controller.

Potential applications include:

• Production machinery.
• Process lines.
• Industrial pumps.
• Fans.
• Blowers.
• Conveyors.
• Mixers.
• Compressors.
• Material-handling equipment.
• Machine auxiliaries.
• Cooling systems.

---

26. Installation Considerations

Before installing the drive, the following should be checked.

Electrical Supply

Confirm that the available three-phase supply is within the 208…240 VAC range.

Motor

Confirm motor nameplate voltage and current.

The motor’s full-load current should be compared against the drive’s applicable duty rating.

Environment

Check ambient temperature, humidity, altitude, dust, corrosive atmosphere, and vibration.

Cabinet

Provide suitable enclosure protection for the IP20/IP00 open-type drive.

Cooling

Maintain the required airflow and prevent recirculation of hot air.

Grounding

Use an appropriate grounding and bonding system.

Motor Cable

Select motor cable according to current, insulation rating, installation method, cable length, EMC requirements, and local electrical standards.

Braking

If rapid deceleration is required, calculate braking energy and select the appropriate braking resistor arrangement.

---

27. Maintenance Considerations

Routine maintenance should include inspection of:

• Cooling fans.
• Air passages.
• Electrical terminals.
• Grounding connections.
• Motor cables.
• Control wiring.
• Network connections.
• Cabinet ventilation.
• Dust accumulation.
• Signs of overheating.
• Fault history.
• Drive operating temperature.

Cooling fans are particularly important in air-cooled drives. Dust buildup can restrict airflow and increase internal temperature.

A maintenance program should also include periodic inspection of the electrical cabinet and associated motor equipment.

---

31. Five Same-Brand Reference Models

The following models are additional Allen-Bradley PowerFlex 755 models that can be used as reference points when comparing voltage classes and power ranges.

Model	Voltage	Current	Normal Duty	Heavy Duty	Frame	Application Range
20G1AND125AN0NNNNN	480 VAC	125 A	100 HP	75 HP	Frame 6	Medium-power industrial motors
20G1AND156AN0NNNNN	480 VAC	156 A	125 HP	100 HP	Frame 6	Pumps, fans, conveyors, process machinery
20G1AND186AN0NNNNN	480 VAC	186 A	150 HP	125 HP	Frame 6	Higher-power industrial applications
20G1ANC140AN0NNNNN	400 VAC	140 A	75 kW	55 kW	Frame 6	Industrial process equipment
20G1ANF142JA0NNNNN	690 VAC	142 A	132 kW	110 kW	Frame 6	High-voltage industrial drive systems

These models demonstrate the broader PowerFlex 755 range across 400 V, 480 V, and 690 V classes. Their current and motor-power ratings differ significantly, so voltage compatibility must be checked before selecting a substitute or alternative.

---

32. Comparison With 480 VAC Models

The 480 VAC models are intended for a different input-voltage class from the 20G1ANB130JA0NNNNN.

For example, the 20G1AND125AN0NNNNN is rated for 480 VAC and 125 A, with 100 HP Normal Duty and 75 HP Heavy Duty ratings.

The 20G1AND156AN0NNNNN increases the current rating to 156 A and the motor rating to 125 HP Normal Duty and 100 HP Heavy Duty.

These models may appear similar because they belong to the same PowerFlex 755 family, but they should not be treated as direct electrical replacements for a 208…240 VAC model.

---

33. Comparison With 400 VAC Models

The 20G1ANC140AN0NNNNN belongs to the 400 VAC class.

Its published rating is 140 A, with 75 kW Normal Duty and 55 kW Heavy Duty.

This demonstrates how the same PowerFlex 755 family can cover different industrial voltage systems while maintaining a common overall drive architecture.

The input voltage remains one of the first specifications that should be checked when selecting a drive.

---

34. Comparison With 690 VAC Models

The 20G1ANF142JA0NNNNN belongs to the 690 VAC class and is rated at 142 A.

Its Normal Duty rating is 132 kW, with a Heavy Duty rating of 110 kW.

This type of high-voltage model is intended for applications where the plant distribution system and motor voltage are significantly higher than the 208…240 VAC class.

It should not be used as a direct replacement for the 20G1ANB130JA0NNNNN without redesigning the electrical system around the different voltage class.

---

35. Application Selection Guide

Application	Suitability of 20G1ANB130JA0NNNNN	Main Reason
Centrifugal Pump	High	Variable-speed control
Industrial Fan	High	Adjustable airflow
Blower	High	Speed regulation
Conveyor	High	Controlled acceleration and speed
Packaging Machine	High	Adjustable motor speed
Mixer	Suitable	Controlled acceleration and speed
Compressor	Suitable	Variable-speed operation
Material Handling	Suitable	Speed and braking control
High-Inertia Machine	Suitable with correct sizing	Dynamic braking capability
High-Voltage Motor	Not suitable	Input voltage class mismatch
480 VAC Motor	Not directly suitable	Different voltage class
690 VAC Motor	Not directly suitable	Different voltage class

The final selection should always be based on motor nameplate current, voltage, load profile, overload requirements, acceleration/deceleration requirements, environmental conditions, and system protection requirements.

---

36. Advantages for Pump Systems

For pump applications, the main benefit is the ability to adjust motor speed to process demand.

A pump does not always need to operate at maximum speed. When process demand changes, the drive can change motor speed accordingly.

This can improve process control and may reduce unnecessary mechanical and electrical loading.

The drive also provides controlled starting, reducing the abrupt mechanical acceleration associated with direct-on-line starting.

---

37. Advantages for Fan Systems

Fan systems often have highly variable airflow requirements.

Instead of continuously operating at full speed, the motor can be operated at a speed corresponding to the required airflow.

This can make variable-speed operation attractive for:

• HVAC equipment.
• Ventilation systems.
• Exhaust systems.
• Cooling systems.
• Industrial air-handling systems.

The actual energy savings depend on the fan curve, operating point, system resistance, motor efficiency, and operating schedule.

---

38. Advantages for Conveyor Systems

Conveyor systems can benefit from controlled acceleration and deceleration.

The drive can gradually increase motor speed rather than applying full motor torque immediately.

This can reduce:

• Belt shock.
• Gearbox shock.
• Coupling stress.
• Product movement.
• Mechanical vibration.

Network communication can also allow conveyor speed and status to be coordinated with upstream and downstream equipment.

---

39. Advantages for Process Machinery

Industrial process machinery often requires stable and repeatable motor operation.

The drive can provide programmable:

• Speed.
• Acceleration.
• Deceleration.
• Stop behavior.
• Current limits.
• Fault response.
• Network commands.

This allows the motor controller to become part of the machine’s overall operating sequence.

---

40. Advantages of Embedded EtherNet/IP

The embedded EtherNet/IP interface allows the drive to participate in a networked automation architecture without requiring a separate communication interface for basic network integration.

Typical information exchanged with a controller can include:

• Start command.
• Stop command.
• Speed reference.
• Actual speed.
• Output current.
• Drive status.
• Fault status.
• Warning status.
• Operating information.

This can simplify system wiring and provide a more integrated method of monitoring multiple drives.

---

41. Advantages of the Dynamic Braking Arrangement

The DB transistor configuration is useful where controlled stopping is required.

When a motor decelerates, energy can be returned from the motor into the drive’s DC bus. In applications with rapid deceleration or high inertia, that regenerated energy can increase DC-bus voltage.

A braking resistor arrangement can dissipate this energy as heat.

The braking resistor must be sized for the actual application rather than selected solely from the drive horsepower.

---

42. Advantages of the Open-Type Design

The IP20/IP00 open-type configuration is appropriate when the drive is installed inside a properly designed industrial cabinet.

This allows system designers to integrate the drive with:

• Main disconnects.
• Circuit protection.
• Control power supplies.
• Network equipment.
• PLC systems.
• Safety equipment.
• Terminal blocks.
• Contactors.
• Motor protection equipment.

The enclosure should be selected to provide the environmental protection required by the installation.

43. Control and Monitoring

The drive can be integrated into a larger control architecture where motor operation is controlled from an external automation system.

A typical system can include:

Controller → EtherNet/IP Network → PowerFlex 755 Drive → Motor → Machine

The controller can issue speed and operating commands while receiving status and diagnostic information from the drive.

This architecture is useful for multi-drive production systems because operating parameters can be coordinated from one control platform.

44. Maintenance and Diagnostic Benefits

A networked variable-frequency drive provides more operating information than a simple motor starter.

Depending on the programmed system, maintenance personnel can monitor:

• Output current.
• Motor speed.
• Drive status.
• Fault condition.
• Warning condition.
• Operating state.
• Communication status.
• Thermal condition.
• Runtime information.

This information can help maintenance personnel identify problems before they develop into extended downtime.

47. Overall Product Description

The Allen-Bradley 20G1ANB130JA0NNNNN is a Frame 6 PowerFlex 755 air-cooled AC drive designed for three-phase 208…240 VAC industrial motor applications.

Its 130 A Normal Duty rating and 104 A Heavy Duty rating provide a useful capacity range for medium-power motor systems. The Normal Duty rating reaches 50 HP, while the Heavy Duty rating is 45 HP.

The drive combines adjustable-frequency motor control with embedded EtherNet/IP communication, allowing it to be connected directly to a networked industrial control system.

Its AC input with precharge, no-DC-terminal configuration, filtered input arrangement, CM jumper, and DB transistor are part of the defined catalog configuration for this model.

The Frame 6 mechanical package is approximately 665.5 mm high, 308 mm wide, and 346.4 mm deep, with an approximate weight of 37 kg.

For applications such as pumps, fans, blowers, conveyors, compressors, mixers, material-handling equipment, and general process machinery, the drive provides adjustable speed, controlled acceleration and deceleration, network monitoring, and configurable motor-control functions.

The model is particularly useful when the machine needs more control than a conventional fixed-speed starter can provide, while maintaining a conventional industrial drive architecture that can be installed inside a suitable electrical enclosure.

For equipment selection, the most important checks are the actual motor voltage, motor full-load current, required duty rating, load torque characteristics, acceleration and braking requirements, ambient temperature, cabinet ventilation, and available electrical protection.

When these factors are correctly matched, the 20G1ANB130JA0NNNNN provides a practical PowerFlex 755 solution for medium-power three-phase AC motor control systems.
