Allen-Bradley 20G1ANF012JA0NNNNN PowerFlex 755 AC Drive

1. Product Overview

The 20G1ANF012JA0NNNNN is an industrial AC variable-frequency drive belonging to the PowerFlex 755 series.

It is designed for three-phase industrial motor applications requiring adjustable speed, controlled acceleration and deceleration, motor protection functions, network communication, and reliable operation within a high-voltage industrial power system.

This particular model is configured for the 690 VAC class, with a rated output current of 12 A. Its Normal Duty rating is approximately 7.5 kW, while its Heavy Duty rating is approximately 5.5 kW.

The drive uses a Frame 6 mechanical configuration and an air-cooled design. It is an open-type drive with an IP20/IP00 enclosure classification and is intended to be installed inside an appropriate electrical cabinet or enclosure.

The exact catalog number also identifies several important configuration details. The model includes an EMC filter, has the common-mode capacitor jumper installed, and includes an internal dynamic-braking transistor.

The unit is also configured with AC input with precharge, no external DC terminals, embedded EtherNet/IP communication, and a blank/no-HIM arrangement.

For applications where the motor operates at higher industrial voltage levels, this combination of 690 VAC operation, compact Frame 6 construction, integrated communications, filtering, and braking capability makes the model particularly useful for machinery and process equipment requiring more functionality than a basic general-purpose inverter.

3. Complete Model Number

The complete catalog number is:

20G1ANF012JA0NNNNN

The complete model number is important because each section of the catalog number corresponds to a particular configuration.

The model should therefore not be identified only by its 12 A current rating. Two drives can have the same current and voltage rating while having different filtering, braking, common-mode capacitor, enclosure, or option configurations.

4. Main Electrical Parameters

The main electrical characteristic of the 20G1ANF012JA0NNNNN is its 690 VAC three-phase architecture.

This makes it suitable for industrial systems where the motor and electrical distribution are designed around a higher-voltage supply.

Electrical Parameter	Specification
Model	20G1ANF012JA0NNNNN
Input Voltage Class	690 VAC
Input Phase	3-phase
Output Current	12 A
Normal Duty Power	7.5 kW
Heavy Duty Power	5.5 kW

Approx. Dimensions	665.5 × 308.0 × 346.4 mm
Approx. Weight	38.6 kg

The Normal Duty and Heavy Duty ratings should be considered according to the actual load profile.

A relatively stable centrifugal pump or fan load may be evaluated differently from a conveyor, mixer, hoist, or other machine that requires repeated acceleration and higher short-term torque.

---

5. Normal Duty and Heavy Duty Operation

The drive provides two principal power ratings.

The 7.5 kW Normal Duty rating is intended for applications where the load profile and overload requirements are within the Normal Duty operating range.

The 5.5 kW Heavy Duty rating reflects the more demanding thermal and overload requirements associated with Heavy Duty operation.

Rating	Power	Approx. HP Class	Typical Load Characteristics
Normal Duty	7.5 kW	Approx. 10 HP	Pumps, fans, blowers and relatively stable loads
Heavy Duty	5.5 kW	Approx. 7.5 HP	Conveyors, mixers and more demanding loads
Output Current	12 A	—	Main continuous current rating
Voltage Class	690 VAC	—	Three-phase industrial supply

The difference between the two ratings is important when selecting the drive.

A motor nameplate showing a particular horsepower value does not automatically determine whether the drive should be selected using the Normal Duty or Heavy Duty rating.

The machine’s torque requirements, acceleration profile, overload frequency, operating speed, inertia, and process requirements should all be considered.

---

6. 690 VAC Industrial Platform

One of the defining characteristics of the 20G1ANF012JA0NNNNN is its 690 VAC voltage class.

Higher-voltage motor systems are common in industrial plants and larger machinery because the higher operating voltage can allow substantial motor power to be transferred with lower current than would be required at a lower voltage.

This makes the 690 VAC PowerFlex 755 configuration useful for industrial equipment where the motor and plant electrical system are already designed around this voltage class.

Applications can include:

• Industrial pumps
• Process fans
• Blowers
• Compressors
• Conveyors
• Material-handling equipment
• Production machinery
• Process equipment
• Large machine tools
• Utility equipment

The motor’s actual rated voltage must always be compatible with the drive and the electrical system.

---

7. Frame 6 Mechanical Construction

The drive uses a Frame 6 mechanical configuration.

This is a larger industrial package than the compact frames used for smaller drives, but it remains substantially more compact than the high-current Frame 7 units used for very large motors.

Mechanical Parameter	Specification
Model	20G1ANF012JA0NNNNN
Frame Size	Frame 6
Approx. Height	665.5 mm
Approx. Width	308.0 mm
Approx. Depth	346.4 mm
Approx. Weight	38.6 kg
Cooling	Air cooled / forced air
Enclosure	IP20/IP00
Enclosure Style	Open Type
Mounting	Cabinet / enclosure installation
Installation Orientation	Vertical industrial mounting
Mounting Hardware	Appropriate Frame 6 mounting hardware
Cabinet Requirement	Suitable electrical enclosure recommended

The approximate dimensions of 665.5 × 308.0 × 346.4 mm should be taken into account when designing the control cabinet.

The listed 38.6 kg weight is also important when selecting the mounting structure and planning installation.

---

8. Product Introduction

The 20G1ANF012JA0NNNNN is designed as a flexible industrial AC drive for applications where precise control of an AC motor is required.

Its 690 VAC three-phase input architecture allows it to be integrated into high-voltage industrial motor systems.

The drive can regulate motor speed by controlling the frequency and voltage supplied to the motor.

Instead of running a motor continuously at a single fixed speed, the drive allows the operating speed to be adjusted according to process requirements.

This is particularly useful when the machine does not need full speed at all times.

For example, a pump may need different flow rates during different stages of production. A fan may need reduced speed when airflow demand falls. A conveyor may need several operating speeds depending on production conditions.

In these situations, variable-speed operation can provide much greater process flexibility than simple fixed-speed motor operation.

---

9. Embedded EtherNet/IP Communication

The model includes embedded EtherNet/IP communication.

This allows the drive to participate in a networked industrial automation system.

In a typical installation, the drive can exchange operating information with the plant control system.

Depending on the control architecture, this can include:

• Start and stop commands
• Speed reference
• Drive status
• Running status
• Fault information
• Diagnostic information
• Operating values
• Control commands

Network communication becomes especially useful when several drives are installed throughout a production line.

Instead of treating every drive as an isolated device, the control system can coordinate multiple motors and machines from a centralized automation environment.

---

10. EMC Filtering

The 20G1ANF012JA0NNNNN includes filtering.

Variable-frequency drives use high-frequency switching devices to generate the desired motor waveform.

That switching action can produce electromagnetic disturbances that need to be considered during system design.

The integrated filtering configuration helps reduce conducted electromagnetic interference within an appropriately designed installation.

However, EMC performance depends on the complete installation.

Motor-cable length, cable shielding, grounding, cabinet design, cable routing, control wiring, and nearby electrical equipment can all affect the actual electromagnetic behavior of the system.

---

11. Common-Mode Capacitor Jumper Installed

This particular catalog number uses the CM jumper installed configuration.

The common-mode capacitor arrangement affects the electrical relationship between the drive, grounding system, and motor system.

This can become important in installations involving particular grounding arrangements or where electromagnetic compatibility needs to be carefully controlled.

The CM jumper configuration is also one of the reasons why the complete catalog number should be checked before replacing an existing drive.

A similar 690 VAC PowerFlex 755 drive may have the same current rating but a different CM jumper configuration.

---

12. Internal Dynamic-Braking Transistor

The model includes an internal dynamic-braking transistor.

This is a useful feature for applications that require controlled motor deceleration.

When a motor decelerates, its stored mechanical energy can be returned toward the drive’s DC bus.

If that energy causes the DC-bus voltage to rise beyond the desired level, a braking system can be used to dissipate the excess energy.

The internal transistor provides the drive-side switching function required for a suitable external braking resistor arrangement.

Potential applications include:

• High-inertia machinery
• Conveyors
• Rollers
• Certain mixers
• Material-handling systems
• Machinery requiring rapid deceleration

The braking resistor itself must be selected according to the required braking energy, resistance value, peak power, continuous power, and duty cycle.

---

13. AC Input with Precharge

The drive uses an AC input with precharge configuration.

The precharge function is important in a high-power electronic drive because it helps control the initial charging of the DC-link capacitors.

Instead of allowing the capacitors to experience an uncontrolled inrush condition, the precharge arrangement manages the initial energization process.

This is particularly important for a drive operating from a 690 VAC industrial system.

---

14. No External DC Terminals

The catalog configuration does not provide external DC terminals.

This should be taken into account when comparing this model with other drive configurations intended for common DC-bus or related architectures.

For a conventional AC-fed motor application, the AC input arrangement provides the primary electrical interface.

When designing a system around this drive, the electrical engineer should therefore consider the specified AC input arrangement and the available terminals rather than assuming that all PowerFlex 755 configurations have identical power interfaces.

---

15. Pump Applications

Pumps are one of the most practical applications for variable-frequency drives.

The 20G1ANF012JA0NNNNN can be considered for industrial pumps where adjustable speed is required.

Examples include:

• Process-water pumps
• Cooling-water pumps
• Circulation pumps
• Water-treatment systems
• Industrial fluid-transfer systems
• Utility pumps
• Chemical process pumps

Variable-speed control allows the pump motor speed to be adjusted according to the required process flow.

Instead of operating the pump continuously at full speed and restricting flow mechanically, the system can change motor speed according to demand.

The actual benefits depend on the pump type, piping system, process requirements, and operating point.

---

16. Fan and Blower Applications

Fans and blowers are another common application for variable-speed motor control.

The drive can regulate motor speed to match airflow requirements.

This is useful in:

• Industrial ventilation
• Exhaust systems
• Cooling systems
• Air-handling equipment
• Process ventilation
• Combustion-air systems
• Industrial blower systems

Fan loads can vary considerably during normal operation.

The ability to reduce motor speed when full airflow is unnecessary can provide useful process flexibility and may reduce operating energy under suitable conditions.

---

17. Conveyor Applications

Conveyor systems often require controlled acceleration and deceleration.

A conveyor carrying material may experience significant mechanical stress if the motor starts too aggressively.

The variable-frequency drive allows the acceleration rate to be controlled.

This can help coordinate motor startup with the mechanical characteristics of the conveyor.

The same principle applies to stopping.

Where the application requires faster deceleration, the internal braking transistor can support an appropriately designed dynamic-braking system.

Typical applications include:

• Manufacturing conveyors
• Packaging conveyors
• Material-transfer systems
• Assembly-line conveyors
• Bulk-material handling
• Warehouse equipment

---

18. Compressor Applications

The drive can also be considered for appropriate compressor applications.

Compressors often require controlled acceleration because the mechanical load can change significantly during startup.

Variable-speed operation can also be useful where the process does not require the compressor to operate continuously at full speed.

Potential applications include:

• Industrial air compressors
• Process compressors
• Refrigeration-related systems
• Gas-handling equipment
• Utility compressor systems

Compressor selection requires special attention to minimum speed, lubrication, cooling, process pressure, mechanical resonance, and manufacturer requirements.

---

19. Mixer and Agitator Applications

Mixers and agitators can have demanding starting characteristics.

When a vessel contains a viscous material, the motor may need considerably more torque at startup than during normal operation.

The drive can provide controlled acceleration and adjustable motor speed.

This can make it useful for:

• Chemical mixing
• Water treatment
• Industrial blending
• Process agitation
• Material mixing
• Manufacturing equipment

Where high starting torque or frequent acceleration is required, the Heavy Duty rating should be evaluated rather than selecting the drive only from the motor horsepower.

---

20. Material-Handling Applications

Material-handling systems often involve several motors operating together.

The embedded network communication of the PowerFlex 755 makes the drive suitable for systems where drive status and operating commands need to be exchanged with a larger control system.

The drive can be integrated into a coordinated machine sequence.

For example, a conveyor can be commanded to start only after another machine reaches the appropriate operating condition.

Similarly, fault information can be communicated back to the control system so that the overall machine can respond appropriately.

---

21. Main Product Advantages

21.1 690 VAC Operation

The 690 VAC voltage class makes this drive suitable for industrial systems using higher-voltage three-phase motors.

This is particularly useful where the plant’s electrical distribution and motor systems are already designed around the 690 VAC class.

---

21.2 Compact Frame 6 Construction

The Frame 6 configuration provides substantial motor-control capability without using the much larger Frame 7 mechanical platform.

With dimensions of approximately 665.5 × 308.0 × 346.4 mm, the drive can fit into many industrial control cabinets designed around medium-sized high-voltage drives.

---

21.3 12 A Output Rating

The 12 A current rating provides suitable capacity for motors in the approximately 7.5 kW Normal Duty class.

The current rating should always be compared with the actual motor nameplate current rather than using horsepower alone.

---

21.4 Integrated Dynamic-Braking Transistor

The internal braking transistor is valuable for applications requiring controlled deceleration.

It provides a convenient drive-side interface for an appropriate external braking resistor system.

---

21.5 Embedded EtherNet/IP

Integrated EtherNet/IP communication simplifies connection to a compatible industrial automation system.

This can reduce the need for additional communication hardware and make the drive easier to integrate into networked machinery.

---

21.6 Integrated Filtering

The filtering configuration helps support electromagnetic compatibility within a correctly designed installation.

This is useful in industrial environments containing instrumentation, controllers, communication equipment, sensors, and other electronic devices.

---

21.7 Flexible Application Range

The drive can be used across many different industrial applications.

It is not limited to one machine type.

The same basic drive platform can be considered for pumps, fans, conveyors, compressors, mixers, blowers, and material-handling equipment when the electrical and mechanical requirements are compatible.

---

22. Five Closely Related PowerFlex 755 Models

The following models are useful when comparing nearby current ratings and configuration options within the same 690 VAC PowerFlex 755 family.

Model	Voltage	Output Current	Normal Duty	Heavy Duty	Frame	CM Jumper	Dynamic Braking	Approx. Dimensions	Approx. Weight
20G1ANF012JA0NNNNN	690 VAC, 3PH	12 A	7.5 kW	5.5 kW	6	Installed	Internal transistor	665.5 × 308.0 × 346.4 mm	38.6 kg
20G1ANF015JA0NNNNN	690 VAC, 3PH	15 A	Approx. 11 kW	Approx. 7.5 kW	6	Installed	Internal transistor	Approx. 665.5 × 308.0 × 346.4 mm	Approx. 38.6 kg
20G1ANF020JA0NNNNN	690 VAC, 3PH	20 A	Approx. 15 kW	Approx. 11 kW	6	Installed	Internal transistor	Approx. 665.5 × 308.0 × 346.4 mm	Approx. 38.6 kg
20G1ANF023JA0NNNNN	690 VAC, 3PH	23 A	Approx. 18.5 kW	Approx. 15 kW	6	Installed	Internal transistor	Approx. 665.5 × 308.0 × 346.4 mm	Approx. 38.6 kg
20G1ANF030JA0NNNNN	690 VAC, 3PH	30 A	Approx. 22 kW	Approx. 18.5 kW	6	Installed	Internal transistor	Approx. 665.5 × 308.0 × 346.4 mm	Approx. 38.6 kg

These models are particularly useful when the motor size changes while the general application architecture remains similar.

The exact power rating should always be verified against the motor current and intended duty classification before selecting a replacement.

---

23. Five Closely Related 690 VAC Models

Another useful comparison is between models with different configuration suffixes.

Model	Voltage	Current	Normal Duty	Heavy Duty	Filtering	CM Jumper	DB Transistor	Frame	Approx. Dimensions	Approx. Weight
20G1ANF012AN0NNNNN	690 VAC	12 A	7.5 kW	5.5 kW	Yes	Removed	No	6	665.5 × 308.0 × 346.4 mm	38.6 kg
20G1ANF012JA0NNNNN	690 VAC	12 A	7.5 kW	5.5 kW	Yes	Installed	Yes	6	665.5 × 308.0 × 346.4 mm	38.6 kg
20G1ANF012JN0NNNNN	690 VAC	12 A	7.5 kW	5.5 kW	Yes	Installed	No	6	665.5 × 308.0 × 346.4 mm	38.6 kg
20G1ANF015JA0NNNNN	690 VAC	15 A	Approx. 11 kW	Approx. 7.5 kW	Yes	Installed	Yes	6	Approx. 665.5 × 308.0 × 346.4 mm	Approx. 38.6 kg
20G1ANF020JA0NNNNN	690 VAC	20 A	Approx. 15 kW	Approx. 11 kW	Yes	Installed	Yes	6	Approx. 665.5 × 308.0 × 346.4 mm	Approx. 38.6 kg

This comparison demonstrates why the complete catalog number matters during replacement.

For example, the JA0 and JN0 versions have different dynamic-braking configurations even though they share the same voltage and current rating.

---

24. Five Same-Brand Popular Models

For applications outside the 690 VAC 12 A range, the following models provide examples of other commonly used drives from the same brand.

Model	Series	Voltage Class	Current / Power Class	Typical Application	Approx. Dimensions	Approx. Weight
25B-D017N104	PowerFlex 525	380–480 VAC	17 A / approx. 10 HP	Compact machinery	Approx. 130 × 260 × 212 mm	Approx. 3.0 kg
25B-D024N114	PowerFlex 525	380–480 VAC	24 A / approx. 15 HP	General machine control	Approx. 130 × 260 × 212 mm	Approx. 3.2 kg
20F11ND034JA0NNNNN	PowerFlex 753	480 VAC class	34 A / approx. 25 HP class	Industrial machinery	Approx. 350 × 170 × 200 mm	Approx. 10 kg
20G1AND125JA0NNNNN	PowerFlex 755	480 VAC	125 A / 100 HP ND	Large industrial motors	Approx. 665.5 × 308.0 × 346.4 mm	Approx. 38.6 kg
20G1ANE125JA0NNNNN	PowerFlex 755	600 VAC	125 A / 125 HP ND	High-voltage industrial motors	Approx. 665.5 × 308.0 × 346.4 mm	Approx. 38.6 kg

The PowerFlex 525 models are much smaller and are intended for a different range of machinery.

The PowerFlex 753 and PowerFlex 755 families are more appropriate for applications where a higher level of industrial drive capability is required.

The PowerFlex 755 models are particularly relevant when the installation requires advanced communication, larger motor capacity, and a broader set of industrial control functions.

---

25. Comparison With the 600 VAC PowerFlex 755 Family

The 690 VAC F-series configuration should not be confused with the 600 VAC E-series configurations.

Both belong to the PowerFlex 755 family, but the voltage classes are different.

For example:

Model	Voltage Class	Current	Normal Duty	Heavy Duty	Frame	Approx. Dimensions	Approx. Weight
20G1ANF012JA0NNNNN	690 VAC	12 A	7.5 kW	5.5 kW	6	665.5 × 308.0 × 346.4 mm	38.6 kg
20G1ANE012JA0NNNNN	600 VAC	12 A	10 HP	7.5 HP	6	665.5 × 308.0 × 346.4 mm	38.6 kg
20G1ANE125JA0NNNNN	600 VAC	125 A	125 HP	100 HP	6	665.5 × 308.0 × 346.4 mm	38.6 kg
20G1ANF061JA0NNNNN	690 VAC	61 A	Higher-power class	Higher-power class	6	Approx. 665.5 × 308.0 × 346.4 mm	Approx. 38.6 kg
20G1ANF119JA0NNNNN	690 VAC	119 A	Approx. 110 kW	Approx. 90 kW	6	Approx. 665.5 × 308.0 × 346.4 mm	Approx. 38.6 kg

The most important point in this comparison is the voltage class.

A 600 VAC drive and a 690 VAC drive should not be treated as interchangeable merely because their mechanical frame and physical dimensions are similar.

---

26. Pump System Advantages

In pump applications, variable-speed control can provide a useful way of matching motor operation to process demand.

A pump may not require maximum flow continuously.

With variable-frequency control, motor speed can be adjusted according to the desired flow or pressure.

This can be useful for:

• Cooling-water circulation
• Industrial water systems
• Process-fluid circulation
• Water treatment
• Utility systems

The actual energy performance depends on the complete hydraulic system, but variable-speed control provides the necessary operating flexibility.

---

27. Fan and Blower Advantages

Fan and blower systems often experience changing airflow requirements.

The drive allows the motor to operate at different speeds rather than remaining permanently at maximum speed.

This can provide better process control.

For example, an industrial exhaust system may require high airflow during one stage of production and lower airflow during another.

The drive can adjust the motor speed to accommodate the process.

---

28. Conveyor Advantages

A conveyor can benefit from controlled acceleration and deceleration.

Starting a conveyor at full speed can place unnecessary mechanical stress on belts, couplings, gearboxes, and other mechanical components.

The drive allows the acceleration profile to be adjusted.

This can provide smoother startup and better coordination with other production equipment.

The internal dynamic-braking transistor can also support controlled stopping when used with a properly selected braking resistor.

---

29. Compressor Advantages

Variable-speed control can be useful when compressor demand changes over time.

Instead of maintaining a single fixed operating point, the motor speed can be adjusted according to process requirements.

This may provide more flexible operation and can help the control system respond to changes in demand.

Compressor applications should always be evaluated using the actual compressor characteristics rather than relying solely on the motor horsepower.

---

30. Industrial Automation Integration

The embedded EtherNet/IP capability is one of the practical advantages of this model.

Modern industrial equipment is increasingly networked.

A drive may need to communicate with:

• Programmable controllers
• Operator interfaces
• Remote I/O
• Production-management systems
• Other motor drives
• Machine controllers

The integrated network capability allows the drive to become part of the larger automation architecture.

This can also simplify troubleshooting because drive status and fault information can be made available to the control system.

---

31. Thermal Management

Although the 20G1ANF012JA0NNNNN is considerably smaller than high-current Frame 7 drives, it still produces heat during operation.

The drive uses air cooling, so airflow must be considered during cabinet design.

Important factors include:

• Ambient temperature
• Cabinet temperature
• Airflow direction
• Ventilation
• Dust accumulation
• Fan condition
• Nearby heat-producing equipment
• Cabinet layout

The drive should not be installed in a location where airflow is blocked.

If several heat-generating components are installed inside the same cabinet, the total cabinet heat load should also be considered.

---

32. Cabinet Installation

The open-type construction means the drive is normally installed as part of an electrical cabinet or suitable enclosure.

The approximate drive dimensions are:

665.5 mm × 308.0 mm × 346.4 mm

The mounting structure must also support approximately:

38.6 kg

Additional cabinet space will be required for power cables, control wiring, grounding, protection equipment, terminal blocks, network wiring, and service access.

Therefore, the cabinet should not be designed using the drive dimensions alone.

---

33. Motor Selection

When selecting a motor for this drive, the motor nameplate should be checked carefully.

Important parameters include:

• Rated voltage
• Rated current
• Rated frequency
• Rated power
• Rated speed
• Motor insulation
• Cooling method
• Starting torque
• Continuous torque
• Overload requirement
• Operating speed range
• Acceleration time
• Deceleration time

The motor’s actual current is particularly important.

A motor listed as approximately 7.5 kW does not necessarily have exactly the same current requirement under every operating condition.

The drive should therefore be selected using the motor’s actual electrical characteristics and the intended duty class.

---

34. Dynamic-Braking Considerations

The internal braking transistor is an important feature, but it should not be confused with a complete braking resistor system.

A dynamic-braking installation normally involves the drive-side transistor and a correctly selected external resistor.

The resistor must be capable of absorbing the energy produced during deceleration.

For a machine with low inertia and infrequent stopping, the braking requirement may be relatively modest.

For a machine with high inertia and frequent stopping, the braking system may need to handle substantial energy repeatedly.

Applications requiring significant braking should therefore be evaluated according to:

• Motor speed
• Load inertia
• Deceleration time
• Stopping frequency
• Mechanical load
• Braking resistor rating
• Peak braking power
• Continuous braking duty

---

35. Maintenance Considerations

Routine maintenance can help keep the drive operating reliably.

Important areas include:

• Cooling airflow
• Fan condition
• Cabinet cleanliness
• Electrical connections
• Grounding connections
• Motor cables
• Braking components
• Network connections
• Fault history
• Environmental conditions

Dust is particularly important in industrial environments.

Accumulated dust can restrict airflow and interfere with thermal management.

The cooling system should therefore be inspected periodically according to the operating environment and maintenance program.

---

36. Troubleshooting Considerations

When troubleshooting the drive, it is useful to divide the problem into several categories.

Power-related problems

Check the incoming three-phase supply, protection devices, input connections, grounding, and power quality.

Motor-related problems

Check the motor nameplate data, motor wiring, insulation, mechanical load, and motor current.

Drive-related problems

Review drive status, fault history, operating parameters, temperature, and cooling conditions.

Communication-related problems

Check the EtherNet/IP connection, network configuration, controller status, and communication parameters.

Braking-related problems

Check the braking resistor, wiring, thermal condition, and deceleration settings when dynamic braking is being used.

A systematic approach is usually more effective than replacing the drive immediately.

---

37. Why the Exact Catalog Number Matters

The difference between closely related catalog numbers can represent a real electrical configuration difference.

For example:

20G1ANF012JA0NNNNN

and

20G1ANF012JN0NNNNN

have the same basic voltage and current class, but their dynamic-braking configurations differ.

Likewise:

20G1ANF012JA0NNNNN

and

20G1ANF012AN0NNNNN

have different CM-jumper configurations and braking arrangements.

Therefore, when replacing an existing drive, the entire catalog number should be recorded.

Selecting only according to voltage, horsepower, or current can result in a replacement that does not reproduce the original electrical configuration.

44. Final Product Description

The Allen-Bradley 20G1ANF012JA0NNNNN PowerFlex 755 AC Drive is a Frame 6, 690 VAC, three-phase industrial variable-frequency drive designed for reliable and flexible AC motor control.

With a 12 A output rating, 7.5 kW Normal Duty capacity, and 5.5 kW Heavy Duty capacity, it is well suited to industrial motors requiring adjustable speed and controlled operation within a higher-voltage electrical system.

Its embedded EtherNet/IP communication, EMC filtering, installed CM jumper, and internal dynamic-braking transistor make it more than a basic speed controller. It can serve as an integrated part of a larger industrial automation system where motor control, communication, diagnostics, and coordinated operation are required.

The Frame 6 construction measures approximately 665.5 mm high, 308.0 mm wide, and 346.4 mm deep, with an approximate weight of 38.6 kg.

For pump, fan, conveyor, compressor, mixer, blower, and material-handling applications, the drive provides a flexible platform for controlling motor speed and managing acceleration and deceleration.

From an engineering perspective, the most important selection points are the 690 VAC voltage class, 12 A output current, 7.5 kW Normal Duty rating, 5.5 kW Heavy Duty rating, Frame 6 mechanical size, dynamic-braking configuration, CM-jumper configuration, EMC filtering, and embedded EtherNet/IP capability.

When selecting a replacement or designing a new system, the complete motor nameplate data, actual load profile, duty classification, braking requirements, cabinet dimensions, cooling arrangement, grounding system, and communication architecture should all be evaluated together.

The 20G1ANF012JA0NNNNN is therefore best understood as a compact-to-medium high-voltage industrial PowerFlex 755 drive intended for applications that require more than basic motor starting and stopping, while still maintaining a practical Frame 6 form factor for industrial cabinet installation.
