5. Dimensions and Weight

The 20F11NB9P6JA0NNNNN uses a Frame 2 package.

Its approximate physical dimensions are:

424.2 mm high × 134.5 mm wide × 212 mm deep

or approximately:

16.70 in high × 5.30 in wide × 8.35 in deep.

The approximate product weight is 7.4 kg (16.37 lb).

These figures describe the drive package itself. The complete installed envelope must be larger because cabinet design also needs to provide space for power cables, control wiring, ventilation, mounting hardware, maintenance access, and the required clearance around the cooling system.

6. Product Introduction

The PowerFlex 753 platform is intended for industrial motor applications where simple ON/OFF motor control is not enough.

The 20F11NB9P6JA0NNNNN provides electronic control over motor speed and acceleration, allowing a motor to operate at different speeds instead of being permanently connected directly to the fixed-frequency supply.

This makes the drive suitable for machines where operating speed is part of the production process.

For example, a conveyor may need to run slowly during loading and faster during normal production.

A pump may need to reduce speed when process demand decreases.

A fan may need to operate at different speeds according to ventilation requirements.

A packaging machine may need controlled acceleration and deceleration between production cycles.

The drive provides the electrical control platform needed for these types of applications.

---

7. 9.6 A Output Rating

The 9.6 A output current rating is the key electrical specification for this model.

It places the drive in the smaller industrial motor range, while still providing enough capacity for many three-phase motors in the 2–3 HP class.

The motor should not be selected solely according to horsepower.

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

Other factors should also be considered, including:

• Motor voltage.
• Motor rated current.
• Normal-duty or heavy-duty operation.
• Starting torque.
• Acceleration time.
• Deceleration time.
• Load inertia.
• Ambient temperature.
• Altitude.
• Motor cable length.
• Operating frequency.
• Required overload capability.

For this reason, a 3 HP motor with an unusually high current requirement should not automatically be assumed to be suitable simply because the horsepower matches.

---

8. Normal Duty and Heavy Duty

The model has two important motor ratings:

Duty Type	Rating
Normal Duty	3 HP / approximately 2.2 kW
Heavy Duty	2 HP / approximately 1.5 kW
Output Current	9.6 A

Normal Duty is generally associated with applications where the drive experiences comparatively moderate overload requirements.

Heavy Duty is more appropriate for applications involving higher starting torque, repeated acceleration, high inertia, or more severe cyclic loading.

Therefore, if a 3 HP motor is used in a demanding application, the Heavy Duty rating should be considered rather than relying only on the 3 HP Normal Duty figure.

For a straightforward fan, conveyor, pump, or similar application with a relatively moderate load profile, the Normal Duty rating may be appropriate.

For a high-torque machine, mixer, loaded conveyor, or equipment with frequent starts and stops, a heavier-duty drive selection may be necessary.

---

9. Embedded I/O

One of the useful features of this configuration is its embedded I/O.

The drive can interface with external control equipment without requiring every basic motor-control function to be provided by separate expansion hardware.

Typical functions can include:

• Start command.
• Stop command.
• Forward command.
• Reverse command.
• External speed reference.
• Run indication.
• Fault indication.
• Digital inputs.
• Analog signals.
• Machine interlocks.
• Process-control signals.

This is particularly useful when the drive is installed inside a machine cabinet and controlled from a PLC or centralized HMI.

---

10. Blank / No HIM Configuration

The model is configured as Blank / No HIM.

HIM means Human Interface Module.

A HIM is normally a local keypad/display used to program, monitor, and troubleshoot the drive.

The absence of a HIM is not necessarily a disadvantage.

In many modern industrial machines, the drive is not operated directly by a person standing in front of it.

Instead, the control architecture may look like:

Operator → HMI → PLC → Drive → Motor

In this arrangement, the machine’s HMI provides the operator interface while the drive performs the actual motor-control function.

A no-HIM configuration can therefore be particularly suitable for:

• Automated machinery.
• PLC-controlled equipment.
• Centralized production lines.
• Machines installed inside electrical cabinets.
• Systems where local drive parameter access is restricted.
• Machines with multiple drives controlled from one HMI.

---

11. Dynamic Braking

The 20F11NB9P6JA0NNNNN includes a dynamic-braking transistor.

This is useful when the application requires controlled motor deceleration.

During deceleration, the motor can return mechanical energy to the drive’s DC bus.

The resulting increase in DC-bus voltage can be managed through a braking circuit using an appropriately selected external braking resistor.

The built-in braking transistor provides the switching function required by this arrangement.

Typical applications include:

• Conveyor systems.
• Material handling.
• Packaging machinery.
• High-inertia rotating equipment.
• Rapidly stopping machines.
• Cutting machinery.
• Feed mechanisms.
• Production machinery requiring controlled stopping.

The braking resistor is application-dependent and must be correctly sized according to braking energy, duty cycle, resistance, and thermal requirements.

---

12. EMC Filtering

The model is configured with EMC filtering and the CM jumper installed.

This is useful in industrial environments where variable-frequency drives operate near control systems, instrumentation, communication equipment, sensors, and other electronic devices.

A variable-frequency drive uses high-frequency switching to create the controlled motor waveform.

That switching action can produce electrical noise.

The filtering and grounding arrangement helps manage these effects.

The complete installation should nevertheless consider:

• Motor cable type.
• Motor cable length.
• Grounding.
• Cabinet grounding.
• Control-cable routing.
• Analog signal routing.
• Communication cables.
• Nearby sensitive electronics.
• Motor insulation.
• Overall EMC requirements.

---

13. Air-Cooled Design

The drive uses forced-air cooling.

This is a common arrangement for industrial variable frequency drives because the power electronics generate heat during normal operation.

The cooling system requires an appropriate airflow path.

The cabinet should not be designed so that hot air from one drive is continuously recirculated through another drive.

When several drives are installed in one enclosure, the total heat generation should be considered.

Cabinet thermal calculations should account for:

• Drive heat losses.
• Ambient temperature.
• Number of drives.
• Other electrical equipment.
• Cabinet dimensions.
• Ventilation fans.
• Heat exchangers.
• Air-conditioning equipment.
• Installation altitude.

---

14. Open-Type Enclosure

The 20F11NB9P6JA0NNNNN uses an Open Type enclosure.

This means it is intended to form part of a larger electrical installation rather than being treated as a completely sealed standalone drive.

It is normally installed inside a suitable industrial control cabinet or enclosure.

The cabinet provides the environmental protection required for the final installation.

The designer therefore needs to consider:

• Dust.
• Moisture.
• Chemical exposure.
• Temperature.
• Airflow.
• Cable entry.
• Electrical safety.
• Operator access.
• Service access.

---

15. Product Applications

15.1 Conveyor Systems

The model is well suited to smaller conveyor systems.

A conveyor motor can be started gradually rather than receiving the full mechanical shock associated with direct starting.

The drive can also allow the conveyor to run at different speeds.

Typical applications include:

• Small belt conveyors.
• Roller conveyors.
• Assembly conveyors.
• Packaging conveyors.
• Feed conveyors.
• Transfer systems.

The 3 HP Normal Duty rating is appropriate for many compact conveyor applications.

---

15.2 Pumps

Small industrial pumps are another suitable application.

The drive can adjust motor speed according to process requirements.

Typical applications include:

• Water circulation.
• Cooling systems.
• Process-fluid circulation.
• Small industrial pumping systems.
• Pressure-control applications.

For variable-torque pump applications, reducing motor speed can also reduce energy consumption under appropriate operating conditions.

---

15.3 Fans

Small industrial fans can benefit from variable-speed control.

The motor can operate at reduced speed when full airflow is not required.

Typical applications include:

• Ventilation.
• Exhaust systems.
• Cooling fans.
• Cabinet ventilation.
• Process-air systems.

---

15.4 Blowers

The same principle applies to small industrial blowers.

The drive can adjust blower speed according to:

• Airflow.
• Pressure.
• Temperature.
• Process requirements.

This can be more flexible than operating the blower continuously at a fixed speed.

---

15.5 Packaging Machinery

Packaging equipment frequently uses smaller motors for:

• Feed mechanisms.
• Conveyor sections.
• Rollers.
• Product transport.
• Material positioning.

The variable-speed function allows these mechanisms to be synchronized with the rest of the production system.

The no-HIM configuration also fits well with centralized machine-control architectures.

---

15.6 Material Handling

Small material-handling systems can use this model for:

• Feed conveyors.
• Small transfer mechanisms.
• Sorting equipment.
• Production-line transport.
• Material feeders.

Controlled acceleration and deceleration can help reduce mechanical stress on belts, chains, couplings, and gearboxes.

---

15.7 Machine Auxiliary Systems

The drive can also be used for auxiliary motors in larger machines.

Examples include:

• Cooling fans.
• Lubrication pumps.
• Auxiliary pumps.
• Small material feeders.
• Exhaust systems.
• Machine ventilation.

Using a dedicated variable-speed drive for an auxiliary motor can improve control flexibility.

---

16. Product Advantages

16.1 Compact Frame 2 Design

The Frame 2 package provides a relatively compact mechanical solution for the 9.6 A class.

With approximately 424.2 × 134.5 × 212 mm dimensions, it can be incorporated into many industrial control cabinets without occupying the space required by larger drive frames.

---

16.2 9.6 A Current Capability

The 9.6 A output rating provides a useful operating range for smaller three-phase industrial motors.

It is particularly suitable for applications in the approximately 2–3 HP class.

---

16.3 3 HP Normal Duty Rating

The 3 HP Normal Duty rating makes the drive suitable for many general-purpose machine applications.

This includes conveyors, pumps, fans, blowers, and other moderate-load equipment.

---

16.4 2 HP Heavy Duty Rating

The 2 HP Heavy Duty rating provides an option for applications requiring greater overload capability.

This is particularly important when the load is more demanding than a simple variable-torque application.

---

16.5 Integrated Dynamic Braking

The internal braking transistor gives the system designer the ability to implement dynamic braking where required.

This can improve stopping performance for applications with higher inertia.

---

16.6 Embedded I/O

Embedded I/O reduces dependence on external hardware for basic drive-control functions.

This can simplify cabinet wiring and machine integration.

---

16.7 No-HIM Architecture

The no-HIM configuration is convenient for centralized control.

The operator can interact with the machine through an HMI while the drive remains inside the electrical cabinet.

---

16.8 EMC Filtering

The filtered configuration is useful in industrial installations where electromagnetic compatibility is an important consideration.

---

16.9 Flexible Motor Control

The PowerFlex 753 platform supports multiple motor-control approaches depending on the overall configuration and application.

This allows the same general drive architecture to be applied to a range of machine requirements.

The 20F11NB9P6JA0NNNNN is the middle reference point in this group.

The smaller 4.2 A and 6.0 A models are useful when the motor current is lower and a smaller capacity drive is sufficient.

The 15 A and 22 A models become more attractive as motor power and current requirements increase.

---

19. Model Selection Within the Same Series

20F11NB4P2JA0NNNNN

This is suitable for smaller motors and lower-current applications.

It can be considered for small fans, pumps, conveyors, and auxiliary machinery.

Its main advantage is that the drive capacity is closer to the actual motor requirement, avoiding unnecessary oversizing.

---

20F11NB6P0JA0NNNNN

The 6.0 A class provides additional capacity over the smaller configuration while remaining appropriate for compact machinery.

It is a practical choice for small industrial motors where the 4.2 A configuration does not provide enough margin.

---

20F11NB9P6JA0NNNNN

This is the reference model.

Its 9.6 A, 3 HP Normal Duty, and 2 HP Heavy Duty ratings make it a good fit for compact industrial machines.

It provides a useful balance between physical size and motor capacity.

---

20F11NB015JA0NNNNN

It is useful when the motor is larger than the typical 3 HP application or when additional current capacity is needed.

---

20F11NB022JA0NNNNN

The 22 A configuration is appropriate for larger industrial machinery.

It can be considered for applications where the 9.6 A model is too small.

---

20. Five Popular Models from the Same Brand

---

23. Application Example — Conveyor

Consider a small conveyor using a 3 HP three-phase motor.

A direct starter can switch the motor on and off, but it does not provide the same degree of speed control.

With the 20F11NB9P6JA0NNNNN, the conveyor can be programmed or commanded to:

• Accelerate smoothly.
• Run at a selected production speed.
• Reduce speed during loading.
• Increase speed during normal transport.
• Decelerate under controlled conditions.
• Stop according to the machine sequence.

This can improve the coordination between the conveyor and other production equipment.

---

24. Application Example — Pump

For a small industrial pump, the drive can adjust motor speed according to the required process condition.

For example, a process may require:

Low demand → low motor speed

Medium demand → medium motor speed

High demand → higher motor speed

This provides greater flexibility than running the pump continuously at full speed.

For centrifugal pumps and other variable-torque applications, variable-speed control can also offer energy-saving potential when operated appropriately.

---

25. Application Example — Fan

A fixed-speed fan normally operates at one speed.

A variable-frequency drive allows the fan speed to follow the actual ventilation requirement.

For example:

Low ventilation demand → low speed

Normal ventilation demand → medium speed

High ventilation demand → high speed

This makes the drive useful for industrial ventilation, exhaust, cooling, and process-air applications.

---

26. Application Example — Packaging Equipment

Packaging machinery often contains several small motors.

Some motors transport products.

Others feed materials.

Others drive rollers or auxiliary mechanisms.

A compact PowerFlex 753 drive can be used to control one of these motors where adjustable speed is required.

The centralized-control configuration is particularly suitable when a PLC and HMI already manage the complete packaging process.

---

27. Application Example — Material Handling

Small material-handling systems can benefit from controlled acceleration.

Starting a loaded conveyor abruptly can produce mechanical shock.

Using a controlled acceleration ramp allows the motor to build speed gradually.

Similarly, controlled deceleration can reduce sudden mechanical loading when the conveyor stops.

This can help improve machine behavior and production consistency.

---

28. Advantages for Control-System Integration

The 20F11NB9P6JA0NNNNN is not simply a motor-speed controller.

It can become part of a larger automation architecture.

A typical system may include:

PLC → control commands → drive → motor

while feedback and status information can move in the opposite direction:

Motor / Drive → status → PLC → HMI

This architecture is common in automated production equipment.

The embedded I/O and expandable architecture make the drive suitable for this type of integration.

---

29. Advantages for Cabinet Design

The Frame 2 package is relatively compact.

The approximate:

424.2 mm × 134.5 mm × 212 mm

envelope makes it easier to integrate into a control cabinet than larger PowerFlex frames.

The approximate 7.4 kg product weight is also manageable for standard industrial panel mounting.

Nevertheless, the final cabinet should provide additional space for:

• Input wiring.
• Motor wiring.
• Control wiring.
• Grounding.
• Ventilation.
• Service access.
• Clearance between components.
• Cable bending radius.

---

30. Maintenance Advantages

The drive is designed for industrial applications and can be incorporated into a structured maintenance program.

Typical maintenance attention should include:

• Cooling fan condition.
• Airflow.
• Dust accumulation.
• Terminal connections.
• Grounding.
• Motor cables.
• Cabinet temperature.
• Drive fault history.
• Braking components where used.
• General cabinet cleanliness.

Maintaining proper airflow is particularly important for air-cooled drives.

---

31. Important Selection Considerations

Before using the 20F11NB9P6JA0NNNNN as a replacement for an existing drive, the following should be checked.

Check Item	Requirement

Cabinet	Verify dimensions and thermal design
I/O	Verify required control signals
HIM	Confirm whether local keypad is required
Communication	Verify required communication architecture
Safety	Verify machine safety requirements
Braking Resistor	Select if dynamic braking is required

---

32. What Makes This Model Different from a Basic Small Drive

Many small variable-frequency drives are intended primarily for simple speed control.

The 20F11NB9P6JA0NNNNN belongs to a more flexible industrial drive architecture.

Its advantages include:

• Embedded I/O.
• Dynamic braking transistor.
• EMC filtering.
• Expandable architecture.
• Industrial control integration.
• Multiple motor-control strategies.
• Centralized-control compatibility.
• Frame-based mechanical construction.
• Industrial diagnostic capabilities.

This makes it suitable for applications where the drive needs to be integrated into a larger automation system rather than operating as an isolated component.

36. Overall Evaluation

The 20F11NB9P6JA0NNNNN is a compact but capable industrial AC drive designed for smaller three-phase motor applications.

Its 9.6 A output rating, 3 HP Normal Duty rating, and 2 HP Heavy Duty rating place it in the smaller industrial machinery segment, while its PowerFlex 753 architecture gives it considerably more flexibility than a basic low-cost variable-speed controller.

The Frame 2 construction keeps the physical package relatively compact.

The approximately 424.2 × 134.5 × 212 mm dimensions allow the drive to fit into many industrial cabinets, while its approximately 7.4 kg weight makes panel installation relatively straightforward.

The combination of embedded I/O, EMC filtering, CM jumper configuration, dynamic-braking transistor, forced-air cooling, AC input with precharge, DC terminals, and no-HIM configuration makes it particularly suitable for automated machines.

38. Final Recommendation

For a 208/240 V three-phase motor in the approximately 2–3 HP range, the 20F11NB9P6JA0NNNNN is a well-balanced PowerFlex 753 configuration.

It is especially appropriate when the application requires more than simple motor ON/OFF control and needs adjustable speed, controlled acceleration, controlled deceleration, embedded I/O, dynamic braking capability, and integration into a PLC/HMI-based automation system.

For a smaller motor, the 4.2 A or 6.0 A configurations may be more economical.

For a larger motor, the 15 A or 22 A configurations provide additional current capacity.

For substantially larger machinery, the 54 A and 70 A PowerFlex 753 configurations become relevant.

From a practical engineering perspective, the most important figures for this particular model are:

9.6 A output current

3 HP Normal Duty

2 HP Heavy Duty
