20G1ANF034JN0NNNNN — 690 V AC Variable Frequency Drive Product Overview

1. Product Introduction

The 20G1ANF034JN0NNNNN is a high-voltage, three-phase AC variable frequency drive designed for industrial motor speed control, torque regulation, acceleration and deceleration management, and process automation applications.

It belongs to the PowerFlex 755 series, a high-performance industrial drive family intended for demanding motor-control applications where stable operation, flexible control, network connectivity, and reliable power handling are important.

This particular model is configured for a 690 VAC three-phase power system and provides a rated output current of 34 A. Its normal-duty rating is 30 kW, while the heavy-duty rating is 22 kW.

The drive uses forced-air cooling and an open-type IP20/IP00 enclosure arrangement, making it suitable for installation inside an electrical cabinet, control panel, or other protected industrial enclosure.

The model includes embedded Ethernet/IP communication, allowing it to be integrated into an industrial automation network without requiring a separate external communication adapter for basic network connectivity.

The JN0 configuration is an important part of the catalog number. Compared with the corresponding JA0 configuration, the JN0 version uses the installed braking-transistor configuration. This can be particularly useful for applications requiring controlled deceleration or connection to an external braking resistor system.

The drive uses an AC input with precharge and does not provide dedicated DC input terminals in this configuration.

2. Basic Product Information

Note: Dimensions and weight should be treated as approximate engineering values for preliminary planning. Actual shipping dimensions, mounting clearances, accessories, terminal arrangements, and cabinet requirements can vary depending on the installed configuration.

---

3. Electrical Parameters

The 34 A output rating is one of the most important selection parameters. When selecting the drive for a motor, the motor’s rated current should be compared directly with the drive output-current capability rather than relying only on the motor’s nominal kW rating.

For normal-duty applications, this model is associated with a 30 kW motor rating. For heavier-duty applications, the corresponding rating is approximately 22 kW.

This difference is important because heavy-duty motor applications generally require greater overload capability and thermal margin. Applications involving frequent acceleration, high starting torque, shock loading, or rapid speed changes should therefore be evaluated according to motor current and duty requirements.

---

4. Voltage and Power Characteristics

The 20G1ANF034JN0NNNNN is designed for the 690 VAC class, making it particularly suitable for industrial facilities using medium/high industrial low-voltage motor systems.

A 690 V motor system can provide advantages in larger industrial installations because higher voltage allows the same motor power to be transferred with lower current compared with a lower-voltage system.

For example, a 30 kW motor operating at a higher voltage can generally have lower line current than an equivalent motor supplied from a 400 V or 480 V system.

This makes 690 V drives attractive in applications such as large fans, pumps, compressors, conveyors, process machinery, and centralized production equipment.

---

5. Normal-Duty and Heavy-Duty Operation

The drive provides different application ratings depending on the required duty level.

Normal-duty operation is generally appropriate for applications where the motor load is comparatively stable and overload requirements are moderate.

Typical examples include centrifugal pumps, fans, blowers, and other variable-torque machinery.

Heavy-duty operation is more relevant to applications where the motor must repeatedly handle higher torque demand, acceleration loads, or mechanical disturbances.

Typical examples include conveyors, mixers, material-handling systems, and machinery with more demanding starting or acceleration conditions.

The motor manufacturer’s full-load current should always be checked when selecting between normal-duty and heavy-duty operation.

---

6. Physical Parameters

The physical installation should provide adequate airflow around the drive. Because the unit uses forced-air cooling, the cabinet should not be designed as a completely sealed enclosure without considering heat dissipation.

The 14.51 kg approximate weight should also be considered when designing the mounting plate, support structure, cabinet back panel, and transportation arrangements.

For final cabinet fabrication, the actual mechanical drawing for the specific revision should be used rather than relying only on the approximate dimensions shown above.

---

---

8. Communication and Automation Capability

One of the significant features of this drive is embedded Ethernet/IP communication.

This allows the drive to become part of a larger industrial automation architecture and exchange operating information with a controller or supervisory system.

Typical information exchanged in an automation system can include:

• Motor speed reference
• Actual motor speed
• Start/stop commands
• Drive status
• Fault information
• Warning information
• Output current
• Output frequency
• Motor operating condition
• Drive diagnostic information
• Acceleration and deceleration commands

This communication capability is particularly useful in production lines where multiple drives must be coordinated from a central control system.

---

9. Applications

Conveyor Systems

The drive can be used for conveyor systems where motor speed needs to be adjusted according to production requirements.

For example, conveyor speed can be synchronized with upstream and downstream machines, allowing material movement to be controlled more smoothly.

The ability to control acceleration and deceleration can also reduce mechanical shock on belts, couplings, gearboxes, and conveyor structures.

---

Pumps

The drive is suitable for industrial pump applications where variable flow is required.

Instead of operating a pump continuously at full speed and controlling flow through mechanical throttling, the motor speed can be adjusted according to process requirements.

This can provide more flexible process control and may reduce unnecessary energy consumption in variable-flow applications.

---

Fans and Blowers

Large industrial fans and blowers are another important application area.

The drive can regulate motor speed according to ventilation, cooling, exhaust, combustion-air, or process requirements.

Variable-speed control can be particularly useful when airflow demand changes throughout the production process.

---

Material Handling Equipment

The 20G1ANF034JN0NNNNN can also be applied to industrial material-handling equipment.

Examples include:

• Conveyors
• Feed systems
• Transfer machines
• Hoists and auxiliary systems
• Production-line transport equipment
• Bulk material handling machinery

The drive’s adjustable acceleration and deceleration characteristics can help reduce sudden mechanical loading.

---

Mixers and Agitators

Mixing equipment frequently requires controlled acceleration and adjustable operating speed.

The drive can provide a controlled motor-speed profile, allowing the process to start gradually and operate at different speeds according to material characteristics.

---

Process Machinery

The drive can be incorporated into production machinery where motor speed is part of the process-control strategy.

Examples include:

• Manufacturing equipment
• Processing machinery
• Production lines
• Machine tools
• Industrial feeders
• Process pumps
• Industrial blowers

10. Main Product Advantages

1. 690 VAC Capability

The 690 VAC rating makes this drive suitable for high-voltage industrial motor systems where a conventional 400 V or 480 V drive would not be appropriate.

This makes the model especially relevant to larger industrial installations.

---

2. 34 A Output Capacity

The 34 A output-current class provides a useful combination of motor power capability and relatively compact installation requirements.

For appropriate motor applications, the drive can support motors in the approximately 30 kW normal-duty class.

---

3. 30 kW Normal-Duty Rating

The 30 kW normal-duty rating allows the drive to be applied to many medium-power industrial machines.

This makes it suitable for pumps, fans, conveyors, process machines, and other equipment where the motor operates within the corresponding current and duty requirements.

---

4. Heavy-Duty Capability

The approximately 22 kW heavy-duty rating provides a separate application point for machines that require more demanding overload performance.

This is useful for machinery where acceleration torque and mechanical loading are more significant.

---

5. Embedded Ethernet/IP

The built-in industrial Ethernet communication capability simplifies integration into automation systems.

It can reduce the need for additional communication hardware and provides a convenient way to exchange control and diagnostic information.

---

6. Forced-Air Cooling

The forced-air cooling arrangement provides active thermal management.

This is important for industrial drives operating under continuous load, particularly when the drive is installed inside a control cabinet with multiple heat-generating components.

Proper cabinet ventilation remains essential.

---

7. Integrated Braking Transistor Configuration

The JN0 configuration is equipped with the relevant braking-transistor arrangement.

This can be useful for applications where braking energy must be managed during deceleration.

Typical applications include machines with relatively high inertia or applications requiring controlled stopping.

---

8. Filtered Configuration

The filtered configuration can be advantageous where electrical noise management and electromagnetic compatibility are important design considerations.

It is particularly useful in industrial control panels containing PLCs, sensors, communication equipment, instrumentation, and other electronic devices.

---

9. Flexible Industrial Application

The drive is not limited to a single type of machinery.

Its combination of high-voltage operation, variable-frequency motor control, industrial networking, braking capability, and cabinet installation makes it suitable for a broad range of production equipment.

---

11. Recommended Same-Series Models

The following models are closely related PowerFlex 755 configurations in the same 690 V class.

These models are useful when selecting a replacement or neighboring capacity within the same product family.

The 20G1ANF030JN0NNNNN is one step below the target model in current capacity, while the 20G1ANF046JN0NNNNN is the next higher current class.

For replacement selection, the most important comparison is not simply the kW rating. The motor full-load current, overload requirement, duty cycle, voltage, braking requirements, enclosure, and environmental conditions should all be checked.

---

12. Additional Same-Series Models

These higher-current versions are suitable for larger motor systems where a 34 A drive is insufficient.

When moving to a higher-current model, however, the cabinet thermal design, cable size, protective devices, mounting requirements, and upstream power distribution should also be reviewed.

---

13. Five Popular Models from the Same Brand

Below are representative popular models from the same manufacturer across different industrial drive families. They are not direct replacements for the 20G1ANF034JN0NNNNN; they are included as related products for comparison and selection.

The models in this table cover different application levels.

The PowerFlex 525 family is generally associated with compact general-purpose machine applications.

The PowerFlex 753 family is oriented toward more advanced industrial motor-control requirements.

The PowerFlex 755 family provides a broader range of high-performance and high-power industrial applications, including the 690 V configuration represented by the target model.

The smaller compact-drive families are more suitable where cabinet space, simplicity, and cost are more important than the higher-end control and power capabilities of the 755 family.

---

14. Comparison with the Target Model

This comparison shows that the target model occupies a useful middle position in the 690 V Frame 6 range.

The 30 A model can be considered when the motor current is lower, while the 46 A model provides additional current capacity when the motor requires greater output capability.

---

15. Installation Considerations

The 20G1ANF034JN0NNNNN is an open-type drive, so it should normally be installed inside a suitable electrical cabinet or enclosure.

The enclosure should protect the drive from excessive dust, moisture, conductive contamination, corrosive gases, mechanical impact, and other environmental conditions that could affect the electronics.

Because the drive uses forced-air cooling, sufficient ventilation space should be maintained around the unit.

The cabinet designer should also account for heat generated by other equipment such as circuit breakers, contactors, transformers, power supplies, PLC equipment, and additional variable frequency drives.

---

16. Motor Selection

When using this drive with a motor, the most important selection criteria are:

1. Motor voltage
2. Motor rated current
3. Motor power
4. Motor frequency
5. Required overload capability
6. Acceleration requirements
7. Deceleration requirements
8. Motor inertia
9. Required braking performance
10. Operating environment

For the target drive, the motor system should be compatible with the 690 VAC class and the drive’s 34 A output-current capability.

A motor with a nominal power rating below 30 kW may still require careful checking if its full-load current is relatively high.

Likewise, simply selecting a 30 kW motor does not automatically guarantee compatibility because motor efficiency, power factor, voltage, service factor, and operating duty can influence actual current requirements.

---

17. Braking Applications

The JN0 configuration is particularly worth noting when braking is part of the application.

During motor deceleration, the motor can return energy to the drive’s DC bus. If this energy is not appropriately managed, the DC bus voltage can rise.

A braking transistor and properly selected external braking resistor can provide a path for managing regenerative energy in suitable applications.

This can be valuable for:

• High-inertia conveyors
• Rapid stopping machinery
• Material-handling systems
• Centrifuges
• Winders and unwinders
• Certain lifting-related equipment
• Machines requiring frequent acceleration and deceleration

The braking resistor must be selected according to the actual regenerated energy, braking duty cycle, resistance requirements, and drive configuration.

---

18. Advantages in Industrial Automation

The main advantage of this drive is the combination of 690 V operation, 34 A output capability, 30 kW normal-duty rating, embedded Ethernet/IP communication, forced-air cooling, filtering, and braking capability in one industrial drive platform.

This combination allows the drive to be used as part of a larger automated production system rather than simply functioning as a standalone motor-speed controller.

For large production systems, network communication is especially useful because drive status, motor speed, current, alarms, and faults can be incorporated into the overall machine-control strategy.

21. Overall Product Description

The 20G1ANF034JN0NNNNN is a 690 V-class industrial variable frequency drive designed for medium-power three-phase motor applications.

With a 34 A output rating, 30 kW normal-duty capacity, and 22 kW heavy-duty capacity, it provides a practical solution for industrial machinery requiring adjustable motor speed and controlled torque.

Its embedded Ethernet/IP communication makes it well suited to networked automation systems, while the forced-air cooling system supports continuous industrial operation when the drive is installed with appropriate cabinet ventilation.

The JN0 configuration is also significant because it incorporates the installed braking-transistor arrangement, making the drive suitable for applications where controlled deceleration and braking-energy management are important.

The filtered open-type configuration allows the drive to be integrated into a properly designed industrial control cabinet, where additional protection, ventilation, circuit protection, disconnecting equipment, and EMC considerations can be provided as part of the complete installation.

For a 690 V industrial motor system requiring approximately 34 A, this model represents a high-capability drive configuration within the PowerFlex 755 family.

When selecting the unit for an actual project, the motor nameplate current should be treated as the primary sizing reference, followed by duty class, overload requirement, braking requirement, environmental conditions, cabinet cooling, and communication requirements.

Important engineering note: the dimensions of approximately 570 × 345 × 377 mm and weight of approximately 14.51 kg are suitable for preliminary product planning, but final cabinet fabrication, mounting-hole layout, cable-entry design, and transportation calculations should be based on the exact mechanical drawing and configuration of the unit being supplied.
