Allen-Bradley 20F1ANF034AN0NNNNN — Detailed Product Specifications, Introduction, Applications, Advantages and Related Models

1. Product Overview

The Allen-Bradley 20F1ANF034AN0NNNNN is a PowerFlex 753 air-cooled AC drive designed for three-phase industrial motor control applications.

This model belongs to the 690 VAC class and provides a nominal output current of 34 A. Its rated capacity is 30 kW for Normal Duty and 22 kW for Heavy Duty, making it suitable for a broad range of medium-power industrial machinery.

The drive uses a Frame 6 construction and an IP20/IP00 Open Type enclosure. It is intended for installation inside an appropriate electrical cabinet or control panel where the required environmental protection, ventilation and electrical clearances can be provided.

A particularly important characteristic of this exact catalog number is its EMC-filtered configuration with the common-mode jumper removed.

The model also has no internal dynamic-braking transistor and is supplied in a blank/no-HIM configuration.

The combination of 690 VAC operation, 34 A output capability, 30 kW Normal Duty capacity, embedded I/O and the flexible PowerFlex 753 architecture makes this model well suited to industrial pumps, fans, blowers, conveyors, process equipment and other variable-speed motor applications.

---

2. Brand and Series

The PowerFlex 753 series is an industrial AC drive platform designed for applications requiring adjustable motor speed, controlled acceleration and deceleration, motor protection, process control and integration with automated machinery.

---

3. Main Technical Parameters

*The listed weight should be treated as an approximate reference because published mechanical data can vary depending on the exact packaged configuration, mounting hardware and accessories. For cabinet engineering, the actual nameplate/package data should be used for the final mechanical design.

---

4. Product Introduction

The 20F1ANF034AN0NNNNN is a high-voltage industrial variable-frequency AC drive intended to control three-phase AC motors.

Rather than operating a motor continuously at the fixed speed determined by the incoming electrical frequency, the drive controls the motor by adjusting the electrical output supplied to the motor.

This allows the motor to run at different speeds according to the requirements of the machine.

In practical industrial equipment, this can be extremely useful.

A pump may only need full speed during periods of high demand.

A fan may need to slow down when ventilation requirements decrease.

A conveyor may require a controlled acceleration profile instead of starting abruptly.

A process machine may require several different operating speeds during different stages of production.

The drive provides the electrical platform required to achieve this type of variable-speed operation.

---

5. 690 VAC Three-Phase Design

One of the most important characteristics of this model is its 690 VAC three-phase rating.

This places it in a higher-voltage industrial motor-control category.

The 690 VAC class is commonly used for larger industrial motors and equipment where higher motor voltage can be beneficial for managing current at a given power level.

For example, when comparing motors with similar power ratings, a higher-voltage motor generally operates at a lower current than an equivalent lower-voltage motor.

This can influence:

• Cable selection
• Distribution design
• Motor starter design
• Drive sizing
• Panel construction
• Protection requirements

The motor must, of course, have an appropriate voltage rating for the intended application.

---

6. 34 A Output Current

The defining electrical characteristic of this model is its 34 A output-current rating.

The 34 A version occupies an important position in the 690 VAC PowerFlex 753 range.

It provides more capacity than the 30 A model while remaining below the larger 46 A and 50 A configurations.

This makes it useful when the motor current is too high for a 30 A drive but does not justify moving to a substantially larger drive.

For drive selection, the motor’s actual nameplate current should always be considered.

The kW rating is useful for preliminary selection, but motor current, duty cycle, overload requirements and operating conditions provide a more complete basis for the final selection.

---

7. 30 kW Normal Duty Rating

The Normal Duty rating of the 20F1ANF034AN0NNNNN is:

30 kW / 34 A

This rating is especially useful for variable-torque applications.

Typical examples include:

• Centrifugal pumps
• Fans
• Blowers
• Ventilation systems
• Cooling systems
• Water circulation
• Air-handling systems
• Fluid-transfer systems

In these applications, the mechanical load often changes with speed.

The drive can therefore adjust motor speed according to the actual process requirement.

---

8. 22 kW Heavy Duty Rating

The Heavy Duty rating is:

22 kW

Heavy Duty operation is more relevant to applications where the motor must provide substantial torque and where acceleration or overload conditions are more demanding.

Examples include:

• Conveyors
• Feeders
• Mixers
• Material-handling machinery
• Processing equipment
• Constant-torque machines

The Heavy Duty rating is lower than the Normal Duty rating because Heavy Duty operation places greater current and thermal demands on the drive.

This distinction is important when selecting a drive for a motor.

A 30 kW motor in a variable-torque pump application and a 30 kW motor driving a heavily loaded conveyor are not necessarily equivalent drive-selection cases.

---

9. Normal Duty and Heavy Duty Comparison

The actual application should determine whether Normal Duty or Heavy Duty sizing is appropriate.

---

10. EMC Filtering Configuration

The 20F1ANF034AN0NNNNN is configured with an EMC filter.

This is one of the important configuration details contained in the catalog number.

The EMC filter can help manage high-frequency electrical noise generated by power-electronic switching.

This is particularly relevant in industrial control panels containing:

• PLC equipment
• HMI equipment
• Communication devices
• Analog instruments
• Sensors
• Measurement equipment
• Other drives
• Industrial control electronics

The filtering arrangement should be considered together with the complete grounding, cable-routing and cabinet design.

---

11. CM Jumper Removed

Another important characteristic is:

CM Jumper Removed

The common-mode jumper configuration affects the drive’s common-mode capacitive connection to ground.

Removing the jumper changes the way common-mode current can flow through the drive’s internal capacitances.

This can be relevant in installations where:

• Grounding conditions are unusual
• Leakage current needs to be managed
• EMC requirements are strict
• Sensitive instrumentation is present
• Multiple drives share the same electrical system
• Long motor cables are used

The correct configuration should be selected according to the electrical system and installation requirements.

---

12. Dynamic Braking

The 20F1ANF034AN0NNNNN does not include an internal dynamic-braking transistor.

This is an important distinction when comparing it with closely related catalog configurations.

During motor deceleration, a motor can act as a generator.

The regenerated energy can return to the drive’s DC bus and increase DC-bus voltage.

If the application requires rapid deceleration, that regenerated energy must be managed appropriately.

For applications with low inertia and relatively long stopping times, dynamic braking may not be necessary.

For high-inertia machinery, rapid stopping or frequent deceleration cycles, a braking solution may need to be evaluated.

---

13. Applications Without Major Braking Requirements

The lack of an internal dynamic-braking transistor is often perfectly acceptable for applications such as:

• Centrifugal pumps
• Large fans
• Blowers
• Ventilation equipment
• Water circulation
• Cooling systems
• Continuous process equipment

These machines often operate for relatively long periods and may not require aggressive stopping.

The motor can simply decelerate according to the programmed ramp.

This makes the no-dynamic-braking configuration practical for many continuous-duty systems.

---

14. Applications With High-Inertia Loads

More attention should be given to braking when the drive controls equipment such as:

• Large flywheels
• High-speed rotating machinery
• Heavy conveyors
• Large mixers
• Loaded material-handling equipment
• Machinery requiring rapid stops
• Machines with frequent start/stop cycles

In these cases, the mechanical energy stored in the rotating system can be significant.

The drive selection should therefore consider:

• Load inertia
• Maximum speed
• Deceleration time
• Number of stopping cycles
• Regenerative energy
• Required stopping performance

The absence of an internal braking transistor does not prevent the drive from being used in such systems, but it does mean that the braking architecture needs to be considered separately.

---

15. AC Input With Precharge

The model uses:

AC Input with Precharge, No DC Terminals

The precharge circuit controls the initial charging of the drive’s internal DC bus.

This is important because the DC bus contains capacitors that would otherwise draw a very large inrush current if connected directly to the incoming supply.

The precharge system helps control this initial energization process.

The model does not provide external DC terminals for a common DC-bus arrangement.

This should be taken into account when designing multi-drive systems or special DC-bus architectures.

---

16. Embedded I/O

The PowerFlex 753 architecture provides embedded I/O for integration with industrial control systems.

This can allow the drive to receive commands and provide status information without requiring a large amount of additional interface equipment.

Common functions can include:

• Start
• Stop
• Enable
• Direction
• Speed reference
• Fault reset
• Drive status
• Digital interlocks
• Analog reference
• Feedback signals

For a conventional industrial machine, embedded I/O can simplify the overall control architecture.

---

17. PID Process Control

PID control is another useful capability for process-oriented applications.

Instead of simply commanding a fixed motor speed, the drive can adjust motor speed based on a process feedback signal.

For example, in a pumping application:

1. The system measures pressure.
2. The measured pressure is compared with the desired pressure.
3. The drive adjusts motor speed.
4. Pump output changes.
5. The system moves toward the desired operating point.

This approach can be useful for:

• Pressure control
• Flow control
• Air pressure
• Ventilation
• Cooling systems
• Fluid circulation
• Water systems

PID control can therefore make the drive more than just a simple speed controller.

---

18. Blank / No HIM Configuration

The model is configured without a dedicated local HIM.

HIM means Human Interface Module.

A blank configuration can be useful where the drive is intended to operate as part of an automated system.

For example, the drive can be controlled by:

• PLC
• HMI
• Digital control signals
• Analog references
• Industrial communications
• Centralized machine-control systems

This approach is common in automated production machinery where operators interact with a higher-level control interface rather than directly with each drive.

---

19. Frame 6 Construction

The drive uses Frame 6 construction.

Frame size affects much more than physical dimensions.

It also relates to:

• Cooling arrangement
• Power component construction
• Terminal layout
• Mounting
• Cabinet space
• Heat dissipation
• Service access
• Cable routing

The Frame 6 platform provides the physical structure needed for this 34 A, 690 VAC drive class.

---

20. Dimensions and Weight

*The approximate weight should be treated as a reference figure rather than a final cabinet-load value because packaged and mechanical configurations can differ. For detailed mechanical engineering, the actual unit should be weighed or its specific equipment documentation checked.

The physical cabinet requirement is larger than the drive body itself.

Additional space should be reserved for:

• Power wiring
• Motor cables
• Control wiring
• Ground connections
• Airflow
• Service access
• Cable bending radius
• Adjacent components

---

21. Open-Type Enclosure

The drive uses an IP20/IP00 Open Type construction.

This means the drive is intended to be installed inside a suitable protective enclosure.

The external cabinet should provide protection appropriate for the surrounding environment.

This becomes especially important in locations containing:

• Dust
• Moisture
• Oil mist
• Metal particles
• Chemicals
• Water spray
• High humidity
• Mechanical contamination

The cabinet must also provide suitable ventilation.

---

22. Forced-Air Cooling

The drive is air cooled using forced airflow.

The power electronics generate heat during operation.

The cooling system transfers this heat away from the internal components and helps maintain acceptable operating temperatures.

Thermal performance depends on:

• Output current
• Motor load
• Ambient temperature
• Cabinet temperature
• Switching conditions
• Airflow
• Fan condition
• Dust accumulation
• Installation altitude

A cabinet with inadequate airflow can cause the drive to operate at an elevated temperature.

For this reason, ventilation should be treated as part of the drive installation rather than as an optional consideration.

---

23. Pump Applications

The 20F1ANF034AN0NNNNN is well suited to pump applications.

Possible applications include:

• Industrial water pumps
• Process pumps
• Cooling-water pumps
• Circulation pumps
• Water-treatment systems
• Fluid-transfer systems
• Pressure-control systems
• Industrial pumping stations

The 30 kW Normal Duty rating is particularly useful for variable-torque centrifugal pump systems.

A drive can adjust pump speed according to process demand rather than operating the pump continuously at full speed.

This can improve process control and may reduce unnecessary motor operation at maximum speed.

---

24. Fan and Blower Applications

Fans and blowers are another strong application area.

Typical uses include:

• Factory ventilation
• Exhaust systems
• Air-handling systems
• Cooling fans
• Industrial blowers
• Process-air systems
• Dust extraction
• Ventilation equipment

Fans commonly operate under variable-speed requirements.

The drive can increase speed when more airflow is required and reduce speed when demand falls.

---

25. Conveyor Applications

Conveyors can use the drive for controlled speed and acceleration.

Potential benefits include:

• Smooth starting
• Reduced mechanical shock
• Adjustable speed
• Controlled acceleration
• Controlled deceleration
• Production-line synchronization
• Improved process coordination

However, conveyor applications should be evaluated according to their torque and braking requirements.

A heavily loaded conveyor may require Heavy Duty sizing.

If the conveyor also needs very fast stopping, the lack of an internal dynamic-braking transistor becomes an important design consideration.

---

26. Mixer Applications

Industrial mixers can have highly variable mechanical loads.

The torque requirement can change according to:

• Material density
• Material viscosity
• Batch size
• Mixing speed
• Material temperature
• Process stage

The 22 kW Heavy Duty rating can make the drive appropriate for many medium-sized mixer applications, provided that the motor current remains within the applicable drive rating.

---

27. Feeder Applications

Feeders require stable and controllable motor speed.

The drive can be used in:

• Material feeders
• Production feeders
• Process feeders
• Bulk material systems
• Dosing equipment
• Production-line feeding machinery

Speed control can help coordinate material flow with other machines in a production process.

---

28. Process Machinery

The drive is also suitable for general process machinery.

Potential applications include:

• Industrial processing equipment
• Fluid-handling machinery
• Cooling systems
• Ventilation machinery
• Production equipment
• Mechanical processing systems
• Automated machinery

The PowerFlex 753 platform is particularly useful where motor control must be integrated with a larger automated system.

---

29. Material Handling

Material-handling machinery often requires controlled motor speed and smooth acceleration.

Examples include:

• Belt conveyors
• Transfer conveyors
• Roller conveyors
• Feed systems
• Production-line handling systems
• Bulk material handling

The drive can provide adjustable speed and controlled acceleration.

The actual motor current and mechanical torque requirements should determine whether Normal Duty or Heavy Duty sizing is appropriate.

---

30. Main Product Advantages

---

31. Main Advantage: 34 A Capacity

The 34 A output capability is one of the strongest characteristics of this model.

It provides more capacity than the 30 A configuration.

This makes it useful when the motor current is close to or above the practical range of the smaller drive.

At the same time, it avoids unnecessarily moving to a much larger 46 A or 50 A configuration.

For equipment designers, this provides a useful intermediate selection point.

---

32. Main Advantage: 30 kW Normal Duty

The 30 kW Normal Duty rating provides substantial capacity for variable-torque machinery.

It is particularly suitable for:

• Pumps
• Fans
• Blowers
• Ventilation systems
• Cooling systems
• Fluid circulation
• Air-handling systems

The drive can therefore serve as the main motor controller in many medium-power industrial systems.

---

33. Main Advantage: 22 kW Heavy Duty

The 22 kW Heavy Duty rating gives the model useful capability for constant-torque equipment.

Applications such as conveyors, feeders and mixers can require higher torque than typical variable-torque equipment.

The Heavy Duty rating should therefore be evaluated separately from the 30 kW Normal Duty rating.

---

34. Main Advantage: EMC Filter

The integrated EMC-filter configuration can be valuable in industrial environments where electrical noise is an important design consideration.

This can help make the drive more suitable for installations containing:

• Control electronics
• Instrumentation
• Communication equipment
• Analog devices
• Sensors
• Other motor drives

Proper grounding and installation practices are still essential.

---

35. Main Advantage: Embedded I/O

Embedded I/O can simplify the control architecture.

Instead of adding separate hardware for every basic drive-control function, the drive can directly interact with the machine-control system.

This can help reduce:

• Wiring
• Panel space
• Interface hardware
• Installation complexity
• Troubleshooting time

---

36. Main Advantage: Industrial Cabinet Integration

The Frame 6 construction is designed for industrial cabinet installation.

The open-type enclosure allows the drive to become part of a larger electrical system.

The cabinet can contain:

• Drive
• Circuit protection
• PLC
• Contactors
• Control transformers
• Communication equipment
• Terminal blocks
• Relays
• Other automation components

Proper spacing and airflow must be maintained.

---

37. Five Recommended Same-Series or Related Models

The following models are useful alternatives around the same PowerFlex 753 690 VAC family.

These alternatives are useful because they allow the user to compare not only power capacity but also filtering and braking configurations.

---

38. Recommended Model 1 — 20F1ANF023AN0NNNNN

The 23 A version is a smaller-capacity alternative.

This model is suitable when the motor current is lower than the 34 A requirement.

---

39. Recommended Model 2 — 20F1ANF030AN0NNNNN

The 30 A version is a close lower-capacity alternative.

This is a practical choice for motors below the 34 A current requirement.

---

40. Recommended Model 3 — 20F1ANF034JN0NNNNN

This model has the same basic 34 A power rating but a different filtering/common-mode configuration.

This model is particularly relevant when the system requires the CM jumper installed configuration.

---

41. Recommended Model 4 — 20F1ANF034JA0NNNNN

This is one of the closest configuration alternatives.

This version is especially relevant when the application requires internal dynamic-braking capability.

---

42. Recommended Model 5 — 20F1ANF046AN0NNNNN

The 46 A model is a higher-capacity alternative.

This model is appropriate when the motor current exceeds the practical capacity of the 34 A version.

---

43. Five Representative Same-Brand Models

The following five models represent useful and commonly encountered alternatives from the same brand across different PowerFlex families.

They should not be treated as direct drop-in replacements for the 20F1ANF034AN0NNNNN.

The first three remain closest to the subject product because they belong to the same general industrial drive family and include 690 VAC PowerFlex 753 configurations.

The PowerFlex 755 and PowerFlex 525 examples represent different drive classes and are more appropriate when the system requirements call for a different architecture, voltage class or power range.

---

44. PowerFlex 753 690 VAC Family Comparison

The 34 A model is positioned between the 30 A and 46 A versions.

This makes it a useful intermediate selection when the 30 A model is insufficient but the 46 A model would provide more capacity than necessary.

---

45. Application Suitability

---

46. Electrical Cabinet Design

Because the drive is an open-type unit, it should normally be incorporated into a suitable electrical cabinet.

The cabinet should provide adequate:

• Environmental protection
• Ventilation
• Electrical separation
• Grounding
• Cable management
• Service access
• Thermal management

The cabinet should not simply be large enough to physically contain the drive.

It must also provide enough space to allow air to circulate and to prevent excessive heat accumulation.

---

47. Cable Management

The motor cable arrangement can have a significant influence on the overall electrical behavior of a variable-frequency drive system.

The installation should take into account:

• Motor cable length
• Cable type
• Grounding
• Shielding
• Cable routing
• Separation from sensitive control wiring
• Communication cables
• Analog signal cables
• Other power cables

This is particularly important in an installation using an EMC filter.

---

48. Grounding Considerations

Proper grounding is fundamental to reliable drive operation.

The installation should provide appropriate grounding for:

• Drive enclosure
• Motor
• Motor cable
• Cabinet
• Control system
• Other connected equipment

The removed CM jumper configuration should also be considered as part of the overall grounding and common-mode-current strategy.

---

49. Maintenance

Regular preventive maintenance can significantly improve long-term reliability.

---

50. Thermal Management

The 30 kW Normal Duty rating means that the drive may operate at a significant thermal load.

Heat management should therefore be considered during cabinet design.

Important factors include:

• Ambient temperature
• Cabinet internal temperature
• Drive loading
• Motor loading
• Airflow
• Fan condition
• Cabinet ventilation
• Installation altitude
• Dust accumulation

A drive operating continuously at high load needs substantially more thermal attention than a drive operating intermittently at low load.

---

51. Motor Selection Guidelines

The actual motor nameplate current should be compared with the applicable drive current rating.

---

52. Normal Duty Selection Example

Suppose an industrial centrifugal pump uses a motor whose electrical characteristics fall within the drive’s 30 kW Normal Duty range.

The 20F1ANF034AN0NNNNN can be an appropriate candidate if:

• The motor voltage is compatible.
• The motor current is within the drive rating.
• The application is suitable for Normal Duty.
• The cabinet can accommodate the drive.
• The environmental conditions are acceptable.
• The required braking performance does not exceed the configuration’s capabilities.

This is a typical use case for this model.

---

53. Heavy Duty Selection Example

For a conveyor or mixer, the motor may experience higher torque demand.

In such a case, the 22 kW Heavy Duty rating becomes the relevant figure rather than the 30 kW Normal Duty rating.

The selection process should therefore focus on the Heavy Duty motor current and overload requirements.

This is one of the most important points when comparing industrial drive ratings.

---

54. Difference Between the AN, JN and JA Configurations

This comparison demonstrates why the final characters of the catalog number should not be ignored.

The three drives have the same basic voltage and current capacity, but their electrical configurations are different.

---

55. Why Catalog Number Matching Matters

The complete catalog number contains information about the drive’s configuration.

For the subject model:

20F1ANF034AN0NNNNN

the configuration identifies a PowerFlex 753 drive with:

• AC input
• Precharge
• No DC terminals
• Open-type construction
• 690 VAC class
• 34 A rating
• EMC filtering
• CM jumper removed
• No internal dynamic-braking transistor
• Blank/no-HIM configuration

This means that selecting another 34 A PowerFlex 753 solely because it has the same current rating may not result in an electrically identical replacement.

The filtering and braking configuration can be just as important as the voltage and current rating.

---

56. Five Most Relevant Alternatives at a Glance

Among these, the 20F1ANF034JN0NNNNN is particularly close electrically, while the 20F1ANF034JA0NNNNN is the more relevant choice when internal dynamic braking is required.

---

57. Complete Product Parameter Summary

*For final mechanical design, use the actual unit’s dimensional and weight data because accessory and packaging configurations can affect the practical installation weight.

---

58. Overall Advantages for OEM Equipment

For original equipment builders, the 20F1ANF034AN0NNNNN provides a useful combination of high-voltage operation, substantial output current and flexible control.

The 34 A rating provides enough capacity for a broad range of industrial motors.

The 30 kW Normal Duty rating is useful for pumps, fans and other variable-torque machinery.

The 22 kW Heavy Duty rating provides a separate operating point for constant-torque equipment.

Embedded I/O can also simplify the machine’s electrical architecture.

The blank/no-HIM configuration can be advantageous when the machine already has a centralized operator interface.

---

59. Advantages for System Integrators

For system integrators, the drive offers flexibility in cabinet and automation design.

The PowerFlex 753 platform can be incorporated into systems requiring:

• Variable-speed control
• Process control
• Motor protection
• Digital control
• Analog references
• Automated sequencing
• Remote operation
• Industrial networking

The EMC-filtered configuration can also be useful in installations where electrical noise needs to be carefully managed.

---

60. Advantages for Maintenance Teams

From a maintenance perspective, standardizing a machine around a consistent drive family can simplify:

• Spare-parts management
• Parameter management
• Troubleshooting
• Technician training
• Drive replacement
• Preventive maintenance
• Machine documentation

A common drive platform can also make it easier for maintenance personnel to understand similar machines throughout a production facility.

---

61. Recommended Application Matching

---

62. Final Evaluation

The Allen-Bradley 20F1ANF034AN0NNNNN is a substantial PowerFlex 753, 690 VAC, three-phase, 34 A air-cooled AC drive intended for medium-power industrial motor control.

Its 30 kW Normal Duty rating makes it particularly suitable for variable-torque applications such as pumps, fans, blowers, cooling equipment, ventilation systems and fluid-handling machinery.

Its 22 kW Heavy Duty rating gives it useful capability for more demanding constant-torque applications such as conveyors, feeders, mixers and material-handling systems.

One of the most important characteristics of this exact model is the EMC filter with the CM jumper removed.

This configuration should be considered carefully when the drive is being installed into an existing electrical system or when replacing another drive.

Another important characteristic is the absence of an internal dynamic-braking transistor.

For applications with normal or relatively slow deceleration, this may not present any problem.

For high-inertia equipment or machinery requiring rapid stopping, the braking requirements should be evaluated before final selection.

The drive uses a Frame 6 mechanical construction and an approximately 665.5 × 308 × 346.4 mm dimensional class.

Its open-type enclosure means that it should be installed in an appropriate cabinet or electrical enclosure.

The cabinet should provide sufficient environmental protection, ventilation, thermal management, wiring space and service clearance.

The approximately 14.5 kg reference weight should be treated as an approximate value for planning purposes, with the actual equipment configuration used for final mechanical-load calculations.

Overall, the 20F1ANF034AN0NNNNN is a strong industrial drive choice when the application requires 690 VAC operation, 34 A output current, 30 kW Normal Duty capacity, 22 kW Heavy Duty capacity, forced-air cooling, embedded I/O, EMC filtering, CM jumper removed and no internal dynamic braking.

Its position between the 30 A and 46 A models also makes it a practical intermediate solution when selecting a 690 VAC PowerFlex 753 drive.

For final selection, the most important factors are the motor nameplate current, motor voltage, required duty class, load torque, acceleration time, deceleration time, braking requirements, cabinet temperature, installation environment and the exact filtering/common-mode configuration required by the machine.
