20F11ND034JA0NNNNN — Detailed Product Specifications, Product Introduction, Applications, Advantages and Related Models

1. Product Overview

The 20F11ND034JA0NNNNN is a PowerFlex 753 AC drive designed for industrial three-phase AC motor control. It is a medium-power variable-frequency drive intended for machinery and process applications where adjustable motor speed, controlled acceleration and deceleration, motor protection, braking capability and flexible automation integration are required.

The model is rated for a 480 VAC, three-phase power system and provides a 34 A output current rating. Its principal power rating is 25 HP (approximately 18.6 kW) for Normal Duty and 20 HP (approximately 14.9 kW) for Heavy Duty. It uses a Frame 3 mechanical configuration, forced-air cooling and an open-type IP20/IP00 construction.

The model includes embedded I/O, an internal dynamic-braking transistor, a filtered configuration with the CM jumper installed, AC input with DC terminals and a blank front interface without a factory-installed HIM.

For equipment designers, system integrators and maintenance departments, this model is particularly useful when a machine requires more capacity than the smaller PowerFlex 753 drives while retaining the same general drive platform.

The published mechanical dimensions for the Frame 3 configuration are approximately 454 mm high × 190 mm wide × 212 mm deep. A commonly listed equipment weight is approximately 9.98 kg.

The 34 A output rating and 25 HP Normal Duty / 20 HP Heavy Duty ratings are the principal electrical characteristics of this particular configuration.

---

5. Mechanical Dimensions and Weight

Mechanical Item	Value
Height	454 mm
Width	190 mm
Depth	212 mm
Approx. Weight	9.98 kg
Frame Size	Frame 3
Enclosure	IP20/IP00
Cooling	Forced air
Installation	Electrical cabinet / control panel
Mounting Orientation	Vertical

The approximate physical envelope is therefore:

454 mm × 190 mm × 212 mm

For preliminary cabinet design, the drive itself should be allocated more space than its exact outside dimensions because power cables, control wiring, ventilation, maintenance access and optional modules also require room.

The approximately 9.98 kg equipment weight should likewise be considered together with the weight of installed options, wiring and any external braking components when calculating cabinet or mounting-plate loading.

---

6. Electrical Characteristics

The 20F11ND034JA0NNNNN is intended for a 380–480 VAC, three-phase supply, with a nominal voltage class of 480 VAC.

Its continuous output-current class is 34 A, which corresponds to a 25 HP Normal Duty rating. For Heavy Duty operation, the rating is approximately 20 HP.

This difference between Normal Duty and Heavy Duty is important.

A machine driving a centrifugal fan or pump may have relatively predictable loading characteristics, whereas a conveyor, mixer or high-inertia machine may place much greater demands on the drive during starting and acceleration.

For that reason, the correct drive should be selected according to the motor nameplate current and actual load profile rather than horsepower alone.

---

7. Product Introduction

The 20F11ND034JA0NNNNN is essentially the electrical control interface between an industrial AC motor and the plant power system.

A conventional AC motor connected directly to a fixed-frequency supply normally operates at a relatively fixed speed. A variable-frequency drive changes the electrical conditions supplied to the motor so that the motor speed can be controlled according to the requirements of the machine.

This provides much greater flexibility.

For example, a conveyor can run slowly during loading and increase speed during normal production.

A fan can operate at reduced speed when full airflow is unnecessary.

A pump can adjust its speed according to process demand.

A mixer can accelerate gradually and operate at different speeds during different stages of a process.

The same basic drive principle can therefore be applied to a large variety of industrial machines.

---

8. Main Control Functions

8.1 Variable-Speed Operation

The most important function is adjustable motor speed.

The drive generates a controlled three-phase output whose frequency and voltage are adjusted according to the selected motor-control strategy.

This allows the machine operator or automation system to change motor speed without mechanically changing pulleys, gears or other transmission components.

---

8.2 Controlled Acceleration

The drive can be configured to accelerate the motor gradually.

This is particularly valuable for machines with:

• Large rotating inertia
• Long conveyor belts
• Gearboxes
• Heavy rollers
• Large fans
• Pumps with significant fluid inertia
• Mixers
• Material-handling equipment

A controlled acceleration profile can reduce mechanical shock and improve overall machine behavior.

---

8.3 Controlled Deceleration

The same principle applies during stopping.

Instead of abruptly removing the motor command, the drive can reduce the motor speed according to a programmed deceleration profile.

This can make the machine stop more smoothly and reduce stress on mechanical components.

---

8.4 Dynamic Braking

The model contains an internal dynamic-braking transistor.

This is an important feature for applications where the motor needs to decelerate faster than normal coasting would allow.

During deceleration, energy from the rotating load can be returned to the drive’s DC bus.

A suitable braking resistor can then be used to dissipate the excess energy.

The braking transistor is built into the drive, but the braking resistor itself still needs to be correctly selected according to the machine’s stopping time, inertia, braking frequency and thermal requirements.

---

9. Embedded I/O

The 20F11ND034JA0NNNNN includes embedded I/O.

This is useful because many standard machine-control functions can be connected directly to the drive rather than requiring a large amount of additional interface hardware.

Typical applications can use I/O for functions such as:

• Start commands
• Stop commands
• Direction control
• External interlocks
• Fault reset
• Speed references
• Machine status
• Process signals
• Drive-running indications

The actual I/O configuration should always be matched to the electrical control design of the specific machine.

---

10. Industrial Applications

10.1 Conveyor Systems

Conveyors are one of the most natural applications for this type of drive.

A conveyor rarely needs to operate at exactly the same speed under every production condition.

Variable-speed operation allows the conveyor to be synchronized with upstream and downstream equipment.

The controlled acceleration function is also useful because starting a conveyor suddenly can place significant stress on belts, chains, couplings and gearboxes.

The 34 A rating makes this configuration suitable for substantially larger conveyor motors than the smaller PowerFlex 753 models.

---

10.2 Pumps

The drive can be used for industrial pumping systems when the motor current and duty requirements are within the drive rating.

Variable-speed pump control can be useful when flow requirements change throughout the production process.

Instead of continuously operating the pump at full speed, the drive can adjust motor speed according to process requirements.

---

10.3 Fans

Industrial ventilation fans and cooling fans often have changing airflow requirements.

Variable-speed control allows the motor speed to follow the actual demand.

Typical applications include:

• Factory ventilation
• Cooling systems
• Process-air systems
• Extraction systems
• Industrial blowers
• Dust-control equipment

---

10.4 Blowers and Compressors

The drive can also be considered for selected blower and compressor applications.

However, compressor loads should be evaluated carefully because compressor torque characteristics can differ considerably from those of centrifugal fans and pumps.

The motor current, starting torque, acceleration profile and duty cycle should all be considered before selecting the drive.

---

10.5 Mixers and Agitators

Mixing equipment often benefits from adjustable speed.

A machine may require a slow speed during loading and a higher speed during the mixing process.

The drive allows these operating points to be controlled electronically.

Controlled acceleration can also be useful for reducing the mechanical shock associated with starting a mixer containing a heavy load.

---

10.6 Material Handling Machinery

Material-handling machinery can benefit from both variable speed and controlled stopping.

Typical applications include:

• Roller conveyors
• Belt conveyors
• Feeders
• Transfer systems
• Packaging lines
• Industrial material movement
• Production-line equipment

---

10.7 General Manufacturing Machinery

The drive can be incorporated into a wide variety of general industrial machines.

It is particularly useful when a machine needs adjustable motor speed but does not require the extremely high dynamic performance normally associated with a dedicated servo system.

---

11. Product Advantages

11.1 34 A Output Capacity

The 34 A output rating gives this model substantially more capacity than smaller configurations in the same family.

The 25 HP Normal Duty rating makes it appropriate for a broad range of medium-sized industrial motors.

---

11.2 25 HP Normal Duty Rating

The 25 HP Normal Duty rating places the product in a useful range for industrial machinery.

It can cover many applications that are too demanding for small compact drives while remaining considerably smaller than high-power industrial drive systems.

---

11.3 20 HP Heavy Duty Capability

The Heavy Duty rating is approximately 20 HP.

This provides an additional selection point for applications with more demanding load characteristics.

When selecting a drive, the Heavy Duty rating is especially important for applications involving high starting torque, high inertia or frequent acceleration and deceleration.

---

11.4 Internal Dynamic Braking

The internal DB transistor is a practical advantage.

It simplifies the drive architecture when dynamic braking is required because the switching element for the braking resistor is already integrated into the drive configuration.

---

11.5 Embedded I/O

Embedded I/O helps reduce the amount of additional interface equipment required for conventional machine-control functions.

This can make the control cabinet cleaner and can simplify wiring.

---

11.6 Expandable Architecture

The PowerFlex 753 platform is designed to accommodate additional functionality through appropriate option modules.

Depending on the machine, additional I/O, feedback, communication or safety-related functionality can be incorporated.

This makes the drive useful not only for basic motor control but also for more sophisticated industrial automation systems.

---

11.7 Industrial Cabinet Integration

The IP20/IP00 open-type construction makes the drive suitable for installation inside an appropriately designed electrical cabinet.

This is a common arrangement for industrial machinery because the cabinet can provide environmental protection while also housing PLCs, contactors, circuit protection, terminal blocks and other automation equipment.

---

12. Installation Advantages

The Frame 3 construction provides a relatively compact physical arrangement for a 34 A, 25 HP-class industrial drive.

The approximate dimensions are:

454 mm height × 190 mm width × 212 mm depth

The approximately 9.98 kg weight is also manageable for conventional industrial control-panel mounting.

The actual control cabinet should, however, provide additional room around the drive.

---

13. Cooling and Environmental Considerations

The drive uses forced-air cooling.

Heat produced by the power electronics must be removed continuously during operation.

Cabinet designers should therefore consider:

• Ambient temperature
• Cabinet internal temperature
• Air circulation
• Filter cleanliness
• Fan condition
• Heat produced by other equipment
• Installation spacing
• Maintenance access

The published environmental information includes a storage temperature range extending from approximately -40°C to 70°C, while the normal operating environment is subject to the applicable drive derating requirements.

The drive should not simply be installed in an enclosure without considering total cabinet heat dissipation.

---

14. Enclosure and Protection

The 20F11ND034JA0NNNNN uses an IP20/IP00, NEMA/UL Open Type configuration.

This means the drive itself should not be regarded as a completely sealed industrial enclosure.

The surrounding cabinet must provide the necessary protection against the installation environment.

For dusty, humid or corrosive industrial locations, the cabinet construction and environmental-control strategy become particularly important.

---

15. Filtering Configuration

The catalog configuration includes filtering and has the CM jumper installed.

This configuration is relevant to electromagnetic compatibility and common-mode considerations.

The final installation still requires appropriate grounding, cable routing and motor-cable practices.

A drive with an integrated filter does not eliminate the need for correct system-level EMC design.

---

16. HIM Configuration

The catalog number specifies:

Blank — No HIM

The standard configuration therefore does not include a factory-installed Human Interface Module.

This can be advantageous when the drive is controlled from a PLC, HMI or other supervisory system and a local operator interface is not required.

If local drive operation is required, an appropriate interface can be added separately according to the machine design.

---

17. Control and Automation Integration

The PowerFlex 753 architecture is intended for integration into industrial automation systems.

Depending on the installed options and control architecture, the drive can be incorporated into systems requiring:

• PLC control
• Speed references
• Motor status monitoring
• Fault monitoring
• Remote start/stop
• Feedback
• Additional I/O
• Communication
• Safety functions

The exact communication and safety functions available to a particular installation depend on the option hardware selected.

---

18. Recommended Same-Series Models

The following models are useful related choices when selecting another drive within the same PowerFlex 753 family.

The most important difference between these models is generally the available current and corresponding motor-power capacity.

Recommended Model	Series	Input	Output Current Class	Normal Duty	Heavy Duty	Frame	Approx. Dimensions H × W × D	Approx. Weight
20F11ND027JA0NNNNN	PowerFlex 753	380–480 VAC, 3-phase	27 A	Approx. 20 HP	Approx. 15 HP	Frame 3	Approx. 454 × 190 × 212 mm	Approx. 10 kg
20F11ND034JA0NNNNN	PowerFlex 753	380–480 VAC, 3-phase	34 A	25 HP / 18.6 kW	20 HP / 14.9 kW	Frame 3	454 × 190 × 212 mm	9.98 kg
20F11ND041JA0NNNNN	PowerFlex 753	380–480 VAC, 3-phase	Approx. 41 A	Approx. 30 HP	Approx. 25 HP	Frame 4	Approx. 474 × 222 × 212 mm	Approx. 14 kg
20F11ND052JA0NNNNN	PowerFlex 753	380–480 VAC, 3-phase	Approx. 52 A	Approx. 40 HP	Approx. 30 HP	Larger frame	Approx. 540 × 280 × 250 mm	Approx. 25 kg
20F11ND062JA0NNNNN	PowerFlex 753	380–480 VAC, 3-phase	Approx. 62 A	Approx. 50 HP	Approx. 40 HP	Larger frame	Approx. 540 × 280 × 250 mm	Approx. 25 kg

The 20F11ND027JA0NNNNN is the natural lower-current comparison.

The 20F11ND041JA0NNNNN provides additional current capacity for applications where 34 A is not sufficient.

The larger models are more appropriate when the motor size increases substantially.

The exact dimensions and weights of related catalog numbers can vary with frame and configuration, so the figures above should be regarded as engineering-selection values rather than a substitute for the mechanical drawing of the exact catalog number.

---

19. Same-Series Model Selection Comparison

Model	Current Level	Approx. Motor Capacity	Relative Size	Recommended Use
20F11ND027JA0NNNNN	27 A	Around 20 HP ND	Medium	Smaller machinery
20F11ND034JA0NNNNN	34 A	25 HP ND	Medium	Medium industrial machinery
20F11ND041JA0NNNNN	41 A	Around 30 HP ND	Medium-large	Higher-load machinery
20F11ND052JA0NNNNN	52 A	Around 40 HP ND	Large	Larger industrial machines
20F11ND062JA0NNNNN	62 A	Around 50 HP ND	Large	Higher-power motor applications

If the motor is close to the 34 A limit, selecting the next higher current rating may provide a more appropriate engineering margin, particularly where overloads or demanding acceleration are expected.

---

20. Five Related Popular Models from the Same Brand

For a broader product comparison, the following models represent other commonly used drive configurations from the same brand.

Model	Product Series	Input Voltage	Output Current	Typical Power Class	Approx. Dimensions H × W × D	Approx. Weight
25B-D010N114	PowerFlex 525	380–480 VAC, 3-phase	Approx. 10.5 A	Approx. 5 HP	Approx. 152 × 87 × 172 mm	Approx. 1.6 kg
25B-D017N114	PowerFlex 525	380–480 VAC, 3-phase	Approx. 17 A	Approx. 10 HP	Approx. 220 × 109 × 184 mm	Approx. 2.3 kg
25B-D024N114	PowerFlex 525	380–480 VAC, 3-phase	Approx. 24 A	Approx. 15 HP	Approx. 260 × 130 × 212 mm	Approx. 3.9 kg
25B-D030N114	PowerFlex 525	380–480 VAC, 3-phase	Approx. 30 A	Approx. 20 HP	Approx. 260 × 130 × 212 mm	Approx. 3.9 kg
20F11ND034JA0NNNNN	PowerFlex 753	380–480 VAC, 3-phase	34 A	25 HP ND / 20 HP HD	454 × 190 × 212 mm	9.98 kg

The compact models in this comparison are substantially smaller than the Frame 3 PowerFlex 753 configuration.

This makes the smaller drive family attractive when cabinet space is limited and the machine does not require the higher expansion capability of the PowerFlex 753 platform.

---

Very Small Machine	May be oversized	Smaller drive may be more appropriate
Servo Motion	Not the preferred solution	Dedicated servo equipment may be required

---

23. Advantages in Conveyor Applications

For conveyor systems, the 20F11ND034JA0NNNNN offers several practical advantages.

The speed can be adjusted according to the production rate.

Acceleration can be controlled so that the conveyor does not start with an abrupt mechanical shock.

Deceleration can be programmed for smoother stopping.

Multiple conveyor sections can operate at different speeds.

The drive can also be integrated with sensors and machine-control systems through its I/O and optional communication architecture.

---

24. Advantages in Pump Applications

For pump applications, variable-speed operation allows the motor speed to follow process requirements.

This can be useful when the required flow varies throughout the day or production cycle.

For centrifugal pumps, changes in motor speed can have a strong influence on flow, pressure and power consumption.

The drive can therefore provide both process-control flexibility and the potential for energy savings.

Actual energy savings depend on the pump system, operating profile and control strategy and should not be assumed simply because a variable-frequency drive is installed.

---

25. Advantages in Fan Applications

Fans are another common application.

An industrial fan does not always need maximum airflow.

By reducing motor speed when demand is lower, the system can reduce the amount of mechanical work performed by the fan.

The drive also makes it possible to create different operating-speed settings for different production conditions.

This is useful for:

• Cooling
• Ventilation
• Extraction
• Dust collection
• Process-air control
• Equipment cooling

---

26. Advantages in Mixer Applications

Mixers can place significant mechanical demands on a motor.

Starting a heavily loaded mixer at full speed can produce high mechanical stress.

The drive allows the motor to accelerate according to a programmed ramp.

Once the desired operating speed has been reached, the speed can be maintained or adjusted as the process changes.

This makes the drive suitable for many industrial mixing and agitation applications, subject to the actual motor current and load requirements.

---

27. Advantages in Material Handling

Material-handling systems benefit greatly from controlled motor speed.

A conveyor moving too quickly can cause product damage or positioning problems.

A conveyor moving too slowly can reduce production capacity.

Variable-speed control provides a convenient way to match the conveyor to the rest of the production line.

Controlled acceleration and deceleration can also improve product handling and reduce mechanical wear.

---

28. Maintenance Considerations

Regular maintenance of a forced-air AC drive should include inspection of:

• Cooling fans
• Air passages
• Cabinet ventilation
• Electrical connections
• Grounding
• Motor cables
• Control wiring
• Braking components
• Dust accumulation
• Ambient temperature

The cooling system is particularly important.

Dust buildup can restrict airflow and increase operating temperature.

The cabinet environment should therefore be kept within the applicable environmental limits.

---

29. Replacement Considerations

When replacing an existing drive with the 20F11ND034JA0NNNNN, the following parameters should be checked before installation.

Check	Requirement
Supply Voltage	Confirm 380–480 VAC, 3-phase compatibility
Motor Voltage	Confirm motor voltage
Motor Current	Confirm motor current is appropriate for the duty rating
Motor Power	Confirm 25 HP ND / 20 HP HD requirement
Load Type	Determine constant- or variable-torque characteristics
Overload	Check acceleration and overload requirements
Braking	Check stopping time and braking energy
Cabinet	Confirm adequate space
Dimensions	Allow for 454 × 190 × 212 mm drive envelope
Weight	Allow for approximately 9.98 kg
Cooling	Confirm sufficient airflow
HIM	No HIM included in this configuration
I/O	Confirm control wiring compatibility
Communication	Confirm required option hardware
Safety	Confirm required machine-safety architecture
Parameters	Record existing motor and drive settings before replacement

---

30. Important Difference Between Normal Duty and Heavy Duty

One of the most important points when evaluating this model is the difference between Normal Duty and Heavy Duty.

The catalog configuration is rated approximately:

Normal Duty: 25 HP / 18.6 kW

Heavy Duty: 20 HP / 14.9 kW

A machine should not be selected based solely on the larger Normal Duty horsepower number.

If the machine requires frequent high-current acceleration, high starting torque or repeated overload operation, the Heavy Duty rating becomes more relevant.

This is why the motor’s actual nameplate current and the machine’s load profile should be reviewed before final selection.

---

31. Overall Advantages

The main advantages of the 20F11ND034JA0NNNNN can be summarized as follows:

Advantage	Description
34 A Output	Suitable for medium-power industrial motors
25 HP ND	Strong Normal Duty capacity
20 HP HD	Suitable for more demanding load conditions within rating
Frame 3	Practical medium-size mechanical platform
Embedded I/O	Simplifies standard control wiring
Dynamic Braking	Internal DB transistor included

33. Final Evaluation

The 20F11ND034JA0NNNNN is a medium-power industrial AC drive with a strong combination of electrical capacity and application flexibility.

Its 34 A output, 25 HP Normal Duty rating, 20 HP Heavy Duty rating, Frame 3 construction, embedded I/O, internal dynamic-braking transistor, filtered configuration and 480 VAC three-phase input make it suitable for a broad range of industrial motor-control applications.

Its approximate physical dimensions of 454 × 190 × 212 mm and approximate weight of 9.98 kg should be taken into account during cabinet design.

For a medium conveyor, pump, fan, blower, mixer, feeder or material-handling system, this model provides a practical combination of motor capacity and control flexibility.

For a smaller motor, a compact drive can reduce cabinet space and overall equipment size.

For a motor requiring more than the 34 A class, a higher-current PowerFlex 753 configuration is a more logical choice.

The most important point when selecting or replacing this drive is to compare the motor nameplate current, motor voltage, duty category, overload requirements, acceleration/deceleration requirements, braking requirements, environmental conditions and available cabinet space. Horsepower by itself is not sufficient for final drive selection.

For cabinet planning, the key figures to retain are:
