20G1ANF046JA0NNNNN — 690 V AC Variable Frequency Drive

1. Product Overview

The 20G1ANF046JA0NNNNN is a high-voltage, three-phase AC variable frequency drive designed for industrial motor speed control, torque control, acceleration and deceleration management, and automated process applications.

This model belongs to the PowerFlex 755 series and is configured for a 690 VAC three-phase industrial power system. It has a rated output current of approximately 46 A, with a typical 37 kW normal-duty rating and 30 kW heavy-duty rating.

The drive is designed for applications where conventional low-voltage drive products are not suitable, particularly larger industrial machinery, process equipment, conveyors, pumps, fans, blowers, material-handling systems, and production machinery.

The JA0 configuration is important because it identifies a configuration incorporating an internal dynamic-braking transistor. This makes the model particularly useful where controlled deceleration or connection to an external braking resistor is required.

The unit uses forced-air cooling and an open-type installation arrangement. In a normal installation, it is mounted inside an appropriate electrical control cabinet or enclosure with sufficient ventilation and heat dissipation.

The drive also provides embedded Ethernet/IP communication, allowing it to be integrated into industrial automation systems and used as part of a networked motor-control architecture.

---

2. Brand and Series

The PowerFlex 755 series is intended for demanding industrial motor-control applications where a combination of power capacity, network communication, braking capability, and flexible motor control is required.

The 20G1ANF046JA0NNNNN sits within the higher-current portion of the 690 V configuration range and provides more output capacity than the 34 A version.

---

3. Main Technical Parameters

The 46 A output-current rating is the key electrical characteristic of this model.

Compared with a 34 A version, the 46 A model provides additional current capacity and is therefore suitable for larger motors and more demanding load requirements.

For normal-duty applications, the drive is generally associated with motors in the 37 kW class.

For heavy-duty applications, the corresponding rating is approximately 30 kW.

The actual motor selection should always be based primarily on the motor’s rated current and required duty rather than selecting the drive solely from the motor’s nominal kW value.

---

4. Electrical Characteristics

The 690 V class is one of the major reasons to select this model.

For larger industrial motors, operating at 690 V can reduce current compared with equivalent motor power at lower voltage levels. This can be useful when designing motor feeders, switchgear, cable systems, and industrial power-distribution equipment.

The drive is therefore particularly relevant to large industrial plants where 690 V motors are already part of the electrical system.

---

5. Normal-Duty and Heavy-Duty Ratings

The drive has two important application ratings.

Normal-Duty Applications

The 37 kW normal-duty rating is appropriate for applications where the motor load is relatively stable and the overload requirement is moderate.

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

Heavy-Duty Applications

The 30 kW heavy-duty rating is more appropriate for equipment that requires higher overload capability or experiences more demanding starting and acceleration conditions.

Typical examples include conveyors, mixers, material-handling equipment, high-inertia machinery, and certain process machines.

The distinction between the two ratings is important when selecting the drive for an actual machine.

A 37 kW motor used in a demanding heavy-duty application should not automatically be matched to this drive simply because the nominal motor power is 37 kW. The actual motor current and required overload capability must be checked.

---

6. Physical Dimensions and Weight

The approximate dimensions of 570 × 345 × 377 mm are useful for preliminary cabinet planning.

The approximate weight is 14.51 kg, which should be considered when designing the cabinet mounting plate, support structure, transportation arrangement, and installation procedure.

Because this is a forced-air-cooled industrial drive, adequate air circulation should be provided around the cooling area.

For final cabinet fabrication, mounting-hole locations, clearance requirements, cable-routing space, ventilation openings, and service access should be checked against the mechanical documentation for the exact configuration being supplied.

---

7. What the Model Number Means

The complete catalog number is:

20G1ANF046JA0NNNNN

The individual sections provide information about the drive configuration.

20G

1

Identifies the relevant AC-input configuration.

ANF

Identifies the 690 V-class filtered open-type configuration.

046

Corresponds to the 46 A output-current class.

This is one of the most important parts of the model number when comparing different drive sizes.

This is particularly important when comparing the model with configurations that do not include the same braking-transistor arrangement.

NNNNN

The remaining characters represent additional factory configuration options and selections.

For purchasing, replacement, and technical documentation, the complete catalog number should be used.

---

8. Dynamic Braking

One of the notable features of the JA0 configuration is the internal dynamic-braking transistor.

When a motor decelerates, especially a motor connected to a high-inertia mechanical load, energy can flow back toward the drive’s DC bus.

This regenerative energy can increase the DC bus voltage.

A dynamic-braking circuit can be used to control this energy through an appropriately selected braking resistor.

This can be useful in applications requiring:

• Rapid deceleration
• Frequent stopping
• High-inertia load control
• Controlled stopping
• Conveyor braking
• Material-handling equipment
• Certain winding applications
• Machinery with frequent speed changes

The braking resistor must be selected according to the drive configuration, braking resistance requirements, peak braking power, average braking power, and duty cycle.

---

9. Product Applications

Industrial Conveyors

The 20G1ANF046JA0NNNNN can be used for large conveyor systems where controlled motor speed is required.

The drive can provide adjustable acceleration and deceleration, helping reduce sudden mechanical loading on belts, couplings, gearboxes, and other mechanical components.

The 46 A output capacity makes this model suitable for larger conveyor motors than smaller drive configurations.

---

Pumps

Large industrial pumps are another common application area.

The drive can regulate motor speed according to process requirements, allowing the pump to operate at different speeds rather than continuously operating at full speed.

This is particularly useful in applications where flow requirements change during operation.

Typical applications include:

• Water circulation
• Industrial process pumps
• Cooling systems
• Water treatment equipment
• Industrial fluid-transfer systems

---

Fans and Blowers

Large fans and blowers can benefit from variable-speed control.

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

This allows the motor to operate according to actual demand rather than continuously operating at maximum speed.

---

Material Handling

The drive is suitable for industrial material-handling equipment requiring adjustable speed and controlled acceleration.

Applications can include:

• Conveyors
• Transfer systems
• Feed systems
• Bulk material handling
• Production-line transport
• Industrial handling equipment

---

Mixers and Agitators

Industrial mixers can require controlled starting and adjustable operating speed.

The drive can provide a gradual acceleration profile and adjustable speed during normal operation.

The dynamic-braking capability can also be useful when the machine needs controlled deceleration.

---

Process Machinery

The drive can be used in process machinery where motor speed is an important part of the production process.

Examples include:

• Manufacturing equipment
• Processing machinery
• Production lines
• Industrial feeders
• Process pumps
• Blowers
• High-inertia machinery

---

10. Main Product Advantages

1. 690 VAC High-Voltage Capability

The 690 VAC rating allows this drive to be used with industrial motor systems designed around the 690 V class.

This is a major advantage when the plant’s existing motor distribution system is already based on 690 V.

It avoids the need to select a lower-voltage drive that would not match the motor system.

---

2. 46 A Output Current

The 46 A output rating provides considerably more motor capacity than smaller models in the same family.

This makes the model suitable for larger industrial motors and machines.

The higher current capability also provides more flexibility when selecting motors within the permitted operating range.

---

3. 37 kW Normal-Duty Rating

The approximately 37 kW normal-duty rating makes this model suitable for medium-to-large industrial equipment.

It can be applied to applications such as pumps, fans, blowers, conveyors, and process machinery where the motor duty is appropriate.

---

4. 30 kW Heavy-Duty Rating

The 30 kW heavy-duty rating provides an application option for machinery with more demanding torque and overload requirements.

This makes the drive more versatile than a drive intended only for constant, lightly loaded applications.

---

5. Internal Dynamic-Braking Transistor

The JA0 configuration provides an internal braking-transistor arrangement.

This can simplify the overall braking system compared with applications requiring a completely separate external switching device.

The actual braking resistor and braking duty still need to be selected according to the application.

---

6. Embedded Ethernet/IP

Embedded Ethernet/IP communication allows the drive to communicate with an industrial automation system.

This can provide access to:

• Speed reference
• Speed feedback
• Start/stop commands
• Drive status
• Fault information
• Warning information
• Output current
• Output frequency
• Diagnostic information

This is particularly useful in automated production lines where multiple drives are controlled from a central system.

---

7. Forced-Air Cooling

Forced-air cooling provides active thermal management for the drive.

This is useful for continuous industrial operation where the drive may operate under significant electrical load for long periods.

The control cabinet must nevertheless provide sufficient ventilation and heat dissipation.

---

8. Filtered Configuration

The filtered configuration can help with electrical-noise management within an industrial control system.

This can be useful in control cabinets containing PLC equipment, instrumentation, sensors, communication devices, and other sensitive electronics.

---

9. Flexible Industrial Application

The combination of 690 V operation, 46 A output capacity, Ethernet/IP communication, dynamic braking, and industrial cabinet installation makes the model suitable for a broad range of applications.

It is not limited to one particular machine type.

---

11. Recommended Same-Series Models

The following models are useful reference points within the same 690 V PowerFlex 755 family.

The 20G1ANF034JA0NNNNN is particularly useful as a comparison because it is the next lower current class to the target 46 A model.

The 20G1ANF052JA0NNNNN provides a higher current class and can be considered when the motor requires additional current capacity.

When selecting a replacement, the drive should not be selected only by comparing the model’s final current number. Motor full-load current, overload requirements, braking requirements, power system voltage, enclosure conditions, and application duty should all be checked.

---

12. Additional Related Models

These higher-current configurations are useful when the target 46 A capacity is not sufficient.

For larger models, however, cabinet design, feeder protection, cable sizing, heat dissipation, and mounting requirements become increasingly important.

---

13. Five Popular Models from the Same Brand

The following table gives several widely used models from the same brand across different drive families. They are useful for comparison, but they should not be treated as direct substitutes for the 20G1ANF046JA0NNNNN.

These products cover different levels of industrial motor-control requirements.

The PowerFlex 525 family is generally associated with compact and general-purpose industrial machinery.

The PowerFlex 753 family is intended for more advanced industrial applications.

The PowerFlex 755 family is positioned toward higher-performance and higher-power applications, including the 690 V configuration represented by the target model.

---

14. Direct Comparison with the 34 A Model

The target 46 A model provides a meaningful increase in current capability compared with the 34 A version.

For applications where the motor’s full-load current exceeds the practical capability of the 34 A model, the 46 A model can provide the next capacity level within the same configuration family.

---

15. Cabinet Installation

Because the drive is an open-type industrial unit, it should normally be installed within an appropriate electrical enclosure.

The cabinet should provide protection against:

• Excessive dust
• Moisture
• Conductive contamination
• Corrosive substances
• Mechanical impact
• Excessive ambient temperature
• Poor ventilation

The approximate drive dimensions are:

570 mm × 345 mm × 377 mm

The approximate weight is:

14.51 kg

Adequate clearance should be provided around the drive for cooling and maintenance.

The cabinet designer should also consider the heat generated by other electrical equipment installed in the same enclosure.

---

16. Cooling and Thermal Management

The 20G1ANF046JA0NNNNN uses forced-air cooling.

This means that cabinet design is an important part of the overall installation.

A drive may have the correct electrical rating but still experience thermal problems if installed inside a poorly ventilated cabinet.

The cabinet design should therefore consider:

• Ambient temperature
• Internal cabinet temperature
• Airflow
• Fan condition
• Air filter condition
• Heat generated by neighboring components
• Required drive clearance
• Continuous operating load
• Installation altitude
• Dust and contamination

For installations involving multiple drives, the total cabinet heat load should be calculated rather than considering each drive independently.

---

17. Industrial Automation Integration

The embedded Ethernet/IP capability allows the drive to operate as part of a larger automation network.

A typical architecture may include a programmable controller, human-machine interface, network switch, sensors, motor drives, and other field devices.

The drive can participate in this system by exchanging operational and diagnostic information.

Typical network information can include:

• Run command
• Stop command
• Speed reference
• Actual speed
• Output current
• Output frequency
• Drive status
• Fault status
• Warning status
• Diagnostic information

This type of integration is particularly valuable in automated production lines where operators need centralized control and maintenance personnel need access to drive status and diagnostic information.

---

18. Applications Where the Model Is Particularly Suitable

---

19. Advantages Compared with a Smaller Drive

The main advantage of selecting the 20G1ANF046JA0NNNNN instead of a smaller 690 V model is its increased current capacity.

For example, compared with the 34 A configuration, the 46 A model provides an additional current margin for appropriately sized motors.

This can be important when the motor operates under variable loads.

The higher rating can also be useful when the application has more demanding acceleration requirements, although the correct heavy-duty rating must still be observed.

Another advantage is that the model maintains the same general PowerFlex 755 platform characteristics, allowing a plant already using related drives to maintain a more consistent drive architecture.

---

20. Important Selection Points

Before using the 20G1ANF046JA0NNNNN in an actual machine, the following points should be checked.

Motor Current

The motor’s nameplate full-load current should be compared with the drive’s 46 A output capability.

Motor Voltage

The motor must be suitable for the intended 690 V-class system.

Duty

Determine whether the machine is a normal-duty or heavy-duty application.

Acceleration

High acceleration torque may require additional consideration when selecting the drive.

Deceleration

If the machine has high inertia or requires rapid stopping, the braking system should be evaluated carefully.

Braking Resistor

If dynamic braking is required, the braking resistor should be selected according to the actual machine’s braking energy and duty cycle.

Cabinet Cooling

The cabinet must be capable of removing the heat generated by the drive and other components.

Environment

Ambient temperature, humidity, dust, altitude, vibration, and contamination should be considered.

Communication

If Ethernet/IP is used, the network architecture and control strategy should be planned before commissioning.
