The 248 A normal-duty output current is one of the most important characteristics of this model.

For drive selection, the motor’s actual nameplate current should always be compared against the applicable drive current rating.

Horsepower is useful for initial selection, but motor current provides a more direct basis for determining whether a particular drive is adequately sized.

---

5. Normal-Duty Rating

The 20F1AND248JN0NNNNN provides a 200 HP normal-duty rating.

This is approximately equivalent to:

200 HP ≈ 149.2 kW

The normal-duty rating is particularly relevant to applications where the load is relatively smooth and the motor does not continuously require severe overload torque.

Typical examples include:

• Centrifugal pumps
• Large centrifugal fans
• Large blowers
• Cooling systems
• Water circulation equipment
• Process-air equipment
• Certain conveyors with moderate starting requirements

The exact suitability still depends on motor current and application conditions.

---

6. Heavy-Duty Rating

Under heavy-duty conditions, the drive is rated at 150 HP.

This corresponds to approximately:

150 HP ≈ 111.9 kW

The heavy-duty rating is important for applications that experience greater torque requirements, more demanding acceleration or more severe overload conditions.

Potential examples include:

• Conveyors
• Mixers
• Agitators
• Process machinery
• Material-handling systems
• Certain compressors
• Machinery with higher starting torque

The correct duty rating should be selected based on the actual load profile rather than simply choosing the larger horsepower value.

---

7. 248 A Output Capacity

The 248 A normal-duty output rating makes this drive suitable for large industrial motors.

A high-current drive of this class is normally installed in industrial electrical rooms, motor-control cabinets or large machine-control panels.

The current rating provides a considerable operating range for high-power motors.

When evaluating motor compatibility, the following parameters should be checked:

• Motor nameplate current
• Motor voltage
• Motor power
• Motor frequency
• Motor speed
• Motor service factor
• Load torque
• Starting torque
• Overload requirements
• Acceleration time
• Deceleration time
• Operating temperature

A motor should not be selected solely because its horsepower appears to match the drive.

---

8. 480 V Three-Phase Operation

The drive belongs to the 480 V AC three-phase class and accepts approximately 380–480 V AC input.

This voltage class is widely used for large industrial motor systems.

High-voltage-class motor systems are particularly practical for large motors because higher voltage allows substantial power to be transferred without requiring the same current that would be needed at lower voltage.

The drive can therefore be used in large industrial electrical systems involving:

• Large pumps
• Large fans
• Compressors
• Conveyors
• Industrial processing equipment
• Cooling systems
• Manufacturing machinery

---

9. Frame 6 Construction

The 20F1AND248JN0NNNNN uses a Frame 6 construction.

Frame 6 provides a substantial mechanical platform capable of handling the electrical requirements associated with a 248 A drive.

Mechanical Parameter	Specification
Model	20F1AND248JN0NNNNN
Frame	6
Height	Approx. 665.5 mm
Width	Approx. 308.0 mm
Depth	Approx. 346.4 mm
Dimensions	Approx. 665.5 × 308.0 × 346.4 mm
Weight	Approx. 38.6 kg
Cooling	Forced Air
Enclosure	IP00/IP20
Installation	Cabinet / Panel
Mounting Hardware	Suitable Frame 6 mounting hardware

The Frame 6 format provides a useful balance between high electrical capacity and a relatively compact footprint compared with larger Frame 7 configurations.

---

10. Dimensions and Weight

The approximate dimensions of the open-type Frame 6 unit are:

665.5 mm high × 308.0 mm wide × 346.4 mm deep

The approximate equipment weight is:

38.6 kg

Mechanical Specification	Value
Model	20F1AND248JN0NNNNN
Height	665.5 mm
Width	308.0 mm
Depth	346.4 mm
Overall Dimensions	665.5 × 308.0 × 346.4 mm
Weight	38.6 kg
Frame	6
Cooling	Forced Air
Enclosure	IP00/IP20 Open Type

Because the drive is an open-type industrial component, the cabinet designer must provide additional space beyond the physical dimensions.

Cable bending radius, terminal access and ventilation are particularly important for a drive of this size.

---

11. Open-Type Enclosure

The model uses an IP00/IP20-class NEMA/UL Open Type construction.

This type of drive is intended for installation inside an appropriate protected electrical environment.

It is not intended to be treated as a fully sealed outdoor enclosure.

The installation should protect the drive from:

• Water
• Condensation
• Oil
• Corrosive chemicals
• Excessive dust
• Metal particles
• Conductive contamination
• Mechanical impact
• Direct environmental exposure

The open-type design is advantageous for custom control cabinets because the machine builder can determine the overall enclosure architecture.

---

12. Forced-Air Cooling

The drive uses forced-air cooling.

Large industrial drives produce heat as a natural consequence of power conversion.

A cabinet containing a 248 A drive therefore requires careful thermal planning.

The cabinet design should consider:

• Ambient temperature
• Drive heat dissipation
• Cooling-air flow
• Fan condition
• Cabinet ventilation
• Air filters
• Adjacent heat-generating equipment
• Cabinet internal temperature
• Installation spacing

If multiple drives are installed together, the total thermal load of the cabinet must be considered rather than evaluating each drive independently.

---

13. AC Input with Precharge

The 20F1AND248JN0NNNNN uses AC input with precharge.

Precharge is particularly important in a large AC drive because the internal DC bus contains substantial energy-storage components.

The precharge circuit helps manage the initial charging process when the drive is energized.

This makes the input architecture appropriate for a high-power industrial drive of this class.

---

14. No DC Terminals

This particular configuration does not provide external DC terminals.

This is an important distinction when comparing different PowerFlex 753 catalog numbers.

A conventional AC-fed motor application can normally use this configuration without requiring a shared external DC bus.

However, applications involving common DC bus systems, shared regeneration or special DC-bus architectures should be evaluated separately.

---

15. Filtered Configuration

The model is configured with filtering and an installed CM capacitor jumper.

This is beneficial when the drive is integrated into a larger industrial electrical environment containing sensitive electronic equipment.

Examples include:

• PLC systems
• HMIs
• Sensors
• Industrial communication devices
• Instrumentation
• Measurement equipment
• Other variable frequency drives
• Electronic power supplies

Proper installation practices remain essential.

Filtering should be combined with suitable grounding, motor-cable routing and cabinet design.

---

16. Dynamic Braking Configuration

The 20F1AND248JN0NNNNN does not include an internal dynamic-braking transistor.

This is one of the most important catalog configuration details.

For many centrifugal pump and fan applications, this may not create a practical problem because these machines often use relatively gradual acceleration and deceleration.

However, applications involving large rotating inertia can behave very differently.

Examples include:

• Large conveyors
• Centrifuges
• Heavy rotating machines
• High-speed fans
• Certain compressors
• Hoists
• Rapid-stop machinery

If the application needs rapid deceleration, the braking strategy must be evaluated separately.

---

17. Product Introduction

The 20F1AND248JN0NNNNN can be regarded as a high-capacity industrial motor-control solution for applications where conventional motor starters do not provide sufficient speed-control flexibility.

A conventional starter generally controls whether a motor is running or stopped.

A variable frequency drive goes much further.

It can control motor speed by adjusting the output frequency and voltage according to the requirements of the application.

This provides the machine designer with much greater flexibility.

For example, a large pump does not necessarily need to run at full speed all the time.

A fan may require different airflow levels during different production stages.

A conveyor may need a controlled acceleration profile.

A mixer may require several operating speeds.

The 20F1AND248JN0NNNNN can provide the adjustable-speed control needed in these situations.

---

18. Major Product Advantages

18.1 High Power Capacity

The 200 HP normal-duty rating makes the drive suitable for large industrial motors.

This allows one drive to control equipment that would be far beyond the capacity of compact machine-level drives.

---

18.2 High Current Capability

With 248 A normal-duty output current, the drive provides substantial electrical capacity.

This is particularly useful for large motor systems where current is the primary sizing parameter.

---

18.3 480 V Industrial Compatibility

The 380–480 V AC input range makes the drive suitable for common industrial three-phase power systems.

This makes it practical for large factory installations and heavy industrial machinery.

---

18.4 Built-In I/O

The embedded I/O reduces the need for external interface equipment in many standard applications.

This can simplify wiring and provide a straightforward connection between the drive and machine control system.

---

18.5 Flexible Automation Integration

The PowerFlex 753 platform supports expansion for communication, feedback, additional I/O and safety-related functions.

This gives machine designers room to develop more advanced control architectures.

---

18.6 Large-Motor Speed Control

The drive provides adjustable motor speed instead of simple fixed-speed operation.

This is particularly valuable for process applications where machine speed must change according to production demand.

---

18.7 Controlled Acceleration

Controlled acceleration can reduce mechanical shock.

This can help protect:

• Motors
• Gearboxes
• Couplings
• Shafts
• Bearings
• Belts
• Conveyor systems
• Mechanical structures

---

18.8 Controlled Deceleration

The drive can provide controlled deceleration.

However, the lack of an internal dynamic-braking transistor means that applications requiring rapid braking need additional system evaluation.

---

18.9 Cabinet Integration

The open-type Frame 6 construction is suitable for integration into custom industrial electrical cabinets.

This is useful when the drive needs to be combined with:

• Circuit protection
• Contactors
• PLCs
• Communication equipment
• Terminal blocks
• Safety equipment
• Control power supplies
• Other drives

---

19. Pump Applications

Large centrifugal pumps are one of the strongest application areas for this drive.

A pump does not always need maximum motor speed.

The drive can adjust speed according to:

• Pressure
• Flow
• Tank level
• Process demand
• Cooling requirements
• Water circulation requirements

For suitable centrifugal pump systems, variable-speed operation can significantly improve process flexibility.

It can also reduce unnecessary energy consumption when compared with operating a pump continuously at full speed and controlling the process primarily through throttling.

Typical applications include:

• Industrial water systems
• Cooling-water circulation
• Process-water systems
• Water treatment
• Industrial fluid transfer
• Pressure-boosting systems
• Chemical process circulation

---

20. Fan Applications

Large industrial fans can require hundreds of horsepower.

The 20F1AND248JN0NNNNN is suitable for high-power fan and blower systems where the motor current falls within the drive’s applicable rating.

Typical applications include:

• Factory ventilation
• Process ventilation
• Industrial exhaust
• Large air-handling systems
• Cooling fans
• Dust collection
• Mining ventilation
• Furnace ventilation

The drive can vary fan speed according to airflow or pressure requirements.

This can improve process control and may provide energy savings in suitable variable-torque systems.

---

21. Blower Applications

Industrial blowers frequently operate continuously.

A fixed-speed blower can consume considerable energy when the process demand is below maximum capacity.

The drive can adjust the blower speed to match actual demand.

Potential benefits include:

• Adjustable airflow
• Pressure regulation
• Smooth startup
• Reduced mechanical stress
• Improved process control
• Reduced unnecessary full-speed operation

The motor and blower characteristics should still be evaluated before final selection.

---

22. Conveyor Applications

Large conveyor systems can benefit from variable-speed control.

The drive can provide controlled acceleration rather than applying full motor torque instantly.

This can reduce mechanical stress on:

• Conveyor belts
• Gearboxes
• Couplings
• Shafts
• Bearings
• Mechanical frames

Variable speed can also help synchronize different conveyor sections.

However, the application must be evaluated carefully if the conveyor has substantial inertia or requires rapid stopping.

---

23. Compressor Applications

Large compressors can require significant motor power.

Where the compressor is suitable for variable-speed operation, the drive can provide:

• Controlled startup
• Adjustable speed
• Pressure control
• Process regulation
• Reduced mechanical shock
• Improved operating flexibility

Compressor loads can vary considerably.

Therefore, the compressor’s actual torque characteristics should be reviewed rather than assuming that every compressor has the same drive requirements.

---

24. Mixer Applications

Industrial mixers can require different speeds during different stages of operation.

For example:

• Low speed during loading
• Moderate speed during initial mixing
• Higher speed during blending
• Reduced speed during discharge

The 20F1AND248JN0NNNNN can provide the variable-speed control needed for these operating sequences when the motor and mechanical load are properly matched to the drive.

---

25. Agitator Applications

Large agitators are commonly used in:

• Chemical processing
• Water treatment
• Food processing
• Material blending
• Industrial production

Variable-speed control allows the agitator to operate according to the actual process requirement.

This can improve flexibility and reduce unnecessary mechanical stress.

The heavy-duty rating should be considered where the agitator has substantial starting torque or continuously demanding load conditions.

---

26. Material-Handling Applications

The high current capacity makes the drive suitable for substantial material-handling machinery.

Potential applications include:

• Bulk conveyors
• Feed systems
• Transfer systems
• Production conveyors
• Material-processing machines
• Industrial transport systems

The drive can control acceleration, speed and stopping behavior according to the overall machine sequence.

---

27. Process Machinery

The drive can be integrated into industrial process machinery where speed is part of the process.

Potential applications include:

• Production machinery
• Process pumps
• Large fans
• Industrial mixers
• Blowers
• Material-processing systems
• Manufacturing equipment
• Utility systems

The ability to vary motor speed provides a useful additional control variable for machine designers.

---

28. PID and Process Control

PID control can be used when motor speed needs to respond automatically to a process variable.

For example, a pump can regulate:

• Pressure
• Flow
• Tank level

A fan can regulate:

• Air pressure
• Airflow

A process machine can respond to:

• Temperature
• Pressure
• Flow
• Other analog process measurements

The drive can adjust motor speed based on the difference between the actual process value and the desired setpoint.

This reduces the need to create all process-control logic externally.

---

29. Industrial Automation Integration

The PowerFlex 753 platform can be integrated into larger industrial control systems.

Typical systems may include:

• PLC controllers
• Operator interfaces
• Industrial Ethernet
• Analog sensors
• Digital control signals
• Feedback devices
• Safety systems
• Supervisory control systems

Typical information exchanged with a control system can include:

• Start command
• Stop command
• Speed reference
• Actual speed
• Output current
• Drive status
• Fault information
• Warning information
• Operating condition

This allows the drive to become part of the overall machine-control architecture rather than operating as an isolated motor controller.

---

30. Safety and Machine Integration

The PowerFlex 753 platform can be expanded or configured for industrial safety requirements depending on the selected architecture.

Potential applications can include:

• Safe torque removal
• Emergency-stop systems
• Safety interlocks
• Guarding systems
• Controlled machine shutdown

The actual safety architecture must be designed according to the complete machine risk assessment.

The drive itself should be considered one component within the complete safety system.

---

31. Cabinet Design Requirements

Because the 20F1AND248JN0NNNNN is an open-type Frame 6 drive, cabinet design is an important part of installation.

The cabinet should allow room for:

• Incoming power cables
• Motor cables
• Control wiring
• Grounding
• Communication modules
• Safety options
• Ventilation
• Maintenance
• Terminal access
• Heat removal

The physical drive dimensions are approximately:

665.5 × 308.0 × 346.4 mm

However, a cabinet should never be designed using only those three dimensions.

The cabinet must also account for cable bending radius, ventilation and working clearances.

---

32. Thermal Management

Thermal management becomes increasingly important as drive power increases.

The cabinet should have an appropriate method for removing heat generated by:

• The drive
• Other drives
• Contactors
• Transformers
• Power supplies
• Control equipment
• Braking equipment
• Other electrical components

Airflow should be planned so that hot air does not circulate back into the drive cooling intake.

Filters should also be maintained because dust accumulation can restrict airflow and raise internal temperatures.

---

33. Electrical Installation Considerations

Installation Item	Consideration
Input Voltage	380–480 V AC
Input Phase	Three Phase
Normal-Duty Current	248 A
Heavy-Duty Current	186 A
Motor Current	Must remain within applicable rating
Protective Equipment	Correctly sized for installation
Motor Cable	Suitable for motor current and drive application
Grounding	Proper protective grounding required
Cabinet	Protected industrial enclosure
Cooling	Forced-air airflow must be maintained
EMC	Correct grounding and cable routing
Short-Circuit Rating	Must suit the complete installation
Maintenance	Adequate access required

The drive should be treated as part of a complete electrical system.

Protective-device selection, cable sizing and short-circuit considerations must be determined according to the overall installation.

---

34. Motor Selection

The motor nameplate should be checked carefully before selecting the drive.

Motor Parameter	Importance
Rated Voltage	Must be compatible with drive output
Full-Load Current	Primary sizing parameter
Rated Power	General selection reference
Rated Frequency	Required for drive configuration
Rated Speed	Important for control setup
Motor Type	Determines control requirements
Power Factor	Required motor data
Efficiency	Useful operating information
Service Factor	Important for sizing
Encoder	Required for certain closed-loop applications
Load Type	Determines duty requirements
Starting Torque	Important for heavy-duty applications

A 200 HP motor should not automatically be connected to the drive simply because the horsepower values match.

The motor’s actual full-load current and load profile must also be within the appropriate drive rating.

---

35. Normal-Duty vs Heavy-Duty Application Selection

Application	Typical Consideration
Centrifugal Pump	Normal Duty
Centrifugal Fan	Normal Duty
Large Blower	Normal Duty
Cooling Fan	Normal Duty
Water Circulation Pump	Normal Duty
Conveyor	Heavy Duty / Application Specific
Mixer	Heavy Duty / Application Specific
Agitator	Heavy Duty / Application Specific
Compressor	Application Specific
Centrifuge	Application Specific
Crusher	Heavy Duty
Hoist	Special Application
High-Inertia Machine	Application Specific

The final selection should always be based on the actual motor and load conditions.

20F1AND302JN0NNNNN	302 A	248 A	250 HP	200 HP	7	Approx. 72.6 kg

The progression makes the 20F1AND248JN0NNNNN particularly suitable when a motor requires substantially more current than the 150 HP class but does not yet require the larger Frame 7 platform.

---

38. Five Same-Brand Popular Models

The following models provide useful comparison points across the broader Allen-Bradley drive portfolio.

Model	Series	Voltage Class	Power Class	Current Class	Typical Application	Approx. Dimensions	Approx. Weight
20F1AND248JN0NNNNN	PowerFlex 753	480 V	200 HP ND	248 A	Large industrial motors	665.5 × 308 × 346.4 mm	38.6 kg

The models above represent different application levels.

The PowerFlex 753 models are the closest products when high-power general-purpose motor control is required.

The PowerFlex 755 family is more appropriate when the application calls for a broader range of advanced control and system-integration capabilities.

The PowerFlex 525 family is much smaller and is generally more appropriate for compact machine applications.

---

39. Comparison with a Smaller PowerFlex Drive

Typical Use	Large Industrial Motors	Small/Medium Motors

The major difference is the intended motor size.

The 20F1AND248JN0NNNNN is not intended to compete with compact machine drives.

It is designed for large industrial motors where high current capacity and industrial system integration are required.

---

40. Advantages in Large Pump Systems

The drive can provide substantial value in large pumping systems.

A pump driven directly at fixed speed may continuously consume energy even when the process does not require maximum flow.

Variable-speed control allows the motor speed to respond to process demand.

For example, the system can adjust speed according to:

• Discharge pressure
• Flow demand
• Tank level
• Cooling requirements
• Production demand
• Process scheduling

This can provide better process control and, in suitable systems, reduce energy consumption.

---

41. Advantages in Large Fan Systems

Large fans often operate for thousands of hours.

The ability to adjust motor speed provides significant operational flexibility.

The drive can be used to maintain a target:

• Airflow
• Pressure
• Temperature
• Ventilation level

This can also reduce mechanical stress during startup.

For variable-torque fan applications, reducing speed can have a particularly strong effect on power consumption.

---

42. Advantages in Conveyor Systems

Large conveyors can experience considerable mechanical shock if started abruptly.

The drive allows acceleration to be controlled.

This can help reduce:

• Belt tension shock
• Gearbox stress
• Coupling stress
• Shaft stress
• Bearing loading

The drive can also provide adjustable conveyor speed.

This is valuable when multiple production processes need to be synchronized.

However, braking requirements must be evaluated carefully because this particular configuration does not include an internal dynamic-braking transistor.

---

43. Advantages in Mixer and Agitator Systems

Large mixers and agitators frequently require high torque.

The drive’s heavy-duty rating of 150 HP can provide useful capacity for demanding applications when the motor current and load profile remain within the applicable rating.

Variable speed can be used to optimize:

• Mixing speed
• Product quality
• Material consistency
• Startup behavior
• Process sequencing
• Energy consumption

---

44. Advantages in Industrial Blower Systems

Large blowers can benefit from continuous speed adjustment.

Instead of operating at maximum output at all times, the blower can respond to actual process requirements.

Potential advantages include:

• Better pressure regulation
• Better airflow control
• Smooth acceleration
• Reduced mechanical stress
• Improved process flexibility
• Potential energy savings

---

45. High-Inertia Applications

High-inertia machinery requires special attention.

The drive can control acceleration and deceleration, but the mechanical energy stored in a large rotating load must be considered.

Examples include:

• Large fans
• Centrifuges
• Large rollers
• Heavy conveyors
• Flywheel systems
• Certain compressors
• Large rotating production machinery

During deceleration, the motor can operate as a generator and return energy toward the drive’s DC bus.

Because this catalog configuration does not include an internal dynamic-braking transistor, a suitable braking strategy may be required if the application needs rapid stopping.

---

46. Installation and Maintenance

The approximately 38.6 kg weight makes the drive manageable compared with some larger industrial drive configurations, but it should still be handled carefully.

Installation planning should include:

• Proper lifting technique
• Secure mounting
• Adequate cabinet structure
• Correct grounding
• Proper cable routing
• Ventilation
• Maintenance clearance
• Safe access

The cooling system should also be inspected periodically.

Dust and contamination can reduce airflow and increase operating temperature.

---

47. Environmental Considerations

The open-type construction means that the drive should be installed in a controlled industrial environment.

Important environmental considerations include:

• Ambient temperature
• Humidity
• Dust
• Corrosive atmosphere
• Condensation
• Altitude
• Vibration
• Air quality

The drive should not be exposed directly to water or aggressive chemicals.

If the application environment is harsh, the electrical cabinet may need additional environmental protection.

Third, acceleration and deceleration requirements should be evaluated.

Fourth, braking requirements should be considered because this particular configuration does not include an internal dynamic-braking transistor.

Fifth, the cabinet must provide adequate thermal management.

Sixth, the open-type enclosure requires an appropriate protected installation environment.

Seventh, communication, feedback and safety requirements should be considered before the final catalog configuration is selected.

---
