The 20F14NF171JN0NNNNN is a high-power industrial AC drive in the PowerFlex 753 series. It is designed for large three-phase motor applications where high current capacity, reliable variable-speed control, industrial automation integration, and flexible motor-control functions are required.
This model is rated for 690 VAC, three-phase operation and provides a 171 A Normal Duty output rating, corresponding to 160 kW Normal Duty power. Its Heavy Duty rating is 142 A and 132 kW.
The drive uses a Frame 7 mechanical configuration and forced-air cooling. It is an open-type industrial drive intended for installation inside a suitable control cabinet or enclosure.
The catalog number specifies a DC input with precharge, filtered operation with the common-mode capacitor jumper installed, embedded I/O, standard protection, a blank/no-HIM configuration, and no internal dynamic-braking transistor.
The 20F14NF171JN0NNNNN is therefore a particularly suitable choice for large industrial equipment such as pumps, fans, blowers, conveyors, rollers, mixers, material-handling equipment, process machinery, and other high-power motor-driven systems.
Because this model provides 171 A and 160 kW Normal Duty capacity, it is a substantial step above the 142 A / 132 kW configuration. It is appropriate when a smaller 690 VAC PowerFlex 753 drive does not provide enough current or power margin.

The mechanical weight can vary within the Frame 7 range depending on the specific hardware arrangement and configuration. For this reason, approximately 32.9–49.4 kg is a more useful planning range than treating one single weight as universal for every Frame 7 configuration.
The approximate mechanical dimensions of 881.5 × 430 × 349.6 mm are suitable for preliminary cabinet planning. Final installation should always allow additional space for power connections, ventilation, control wiring, communication wiring and service access.

Product Family: PowerFlex 750-Series.
Product Series: PowerFlex 753.
The PowerFlex 753 series is an industrial architecture-class drive family designed for large and demanding motor applications.
Compared with compact variable-frequency drives, the PowerFlex 753 platform provides a larger and more flexible architecture.
It is particularly useful when a machine requires a combination of:
The 20F14NF171JN0NNNNN represents a high-power 690 VAC configuration within this product family.
The primary purpose of the 20F14NF171JN0NNNNN is to control a large three-phase AC motor.
In a conventional fixed-speed motor installation, the motor receives power directly from the electrical supply and normally operates close to its designed operating speed.
A variable-frequency drive changes the electrical conditions supplied to the motor and allows the machine to operate at different speeds.
This provides much greater control over industrial machinery.
For example, a pump does not necessarily need to operate at maximum speed all the time.
A fan may need different airflow depending on the production process.
A conveyor may require controlled acceleration to prevent material movement or mechanical shock.
A mixer may require different speeds during different stages of production.
A roller may need coordinated speed control to maintain the correct production rate.
The drive therefore becomes a central component between the electrical power system, motor, mechanical equipment and automation controller.
| Electrical Parameter | Normal Duty | Heavy Duty |
|---|---|---|
| Model | 20F14NF171JN0NNNNN | 20F14NF171JN0NNNNN |
| Continuous Output Current | 171 A | 142 A |
| Power Rating | 160 kW | 132 kW |
| Voltage | 690 VAC | 690 VAC |
| Phase | 3 Phase | 3 Phase |
| Frame | Frame 7 | Frame 7 |
| Cooling | Forced Air | Forced Air |
| Input | DC Input with Precharge | DC Input with Precharge |
| Dynamic Braking | None | None |
The key electrical rating is 171 A Normal Duty.
At this rating, the drive provides a 160 kW Normal Duty power class.
Under Heavy Duty conditions, the drive is rated at 142 A, corresponding to 132 kW Heavy Duty power.
This makes the model suitable for very large industrial motors.
The distinction between Normal Duty and Heavy Duty should be considered carefully because the correct selection depends on the motor’s nameplate current, torque requirements, overload requirements and operating cycle.
The 160 kW Normal Duty rating makes this model suitable for large motors used in applications where the load is generally stable and the drive is not subjected to the most demanding overload conditions.
Typical Normal Duty applications include:
A 160 kW motor should not be selected solely because its kW rating appears to match the drive.
The actual motor nameplate current must be checked.
Motor efficiency, power factor, operating speed, duty cycle, overload requirements and ambient conditions can all affect the final selection.
The Heavy Duty rating is 142 A / 132 kW.
Heavy Duty operation is relevant when the machine requires greater torque or experiences more demanding load conditions.
Typical applications include:
A 132 kW Heavy Duty motor may be a suitable application when the motor current and complete operating profile remain within the applicable drive rating.
The 20F14NF171JN0NNNNN is designed for 690 VAC, three-phase industrial power systems.
This voltage class is particularly relevant to large motors.
As motor power increases, the current required by the electrical system becomes a significant engineering factor.
A higher motor voltage can allow large amounts of power to be delivered with lower current than would otherwise be required at lower voltage classes.
This can influence:
The 690 VAC class therefore makes this model especially appropriate for large industrial installations rather than small machine applications.
The drive is configured for DC input with precharge.
The associated DC-bus class is approximately 932 VDC.
A DC-bus architecture can be useful in industrial systems where several drives or power-conversion devices share a common electrical bus.
The precharge function is important because high-power drives contain substantial DC-bus capacitance.
When the system is energized, the precharge sequence controls the initial charging of the DC bus.
This can be particularly important in large common-bus systems where several high-power components may be energized within the same electrical architecture.
The exact catalog number 20F14NF171JN0NNNNN specifies no internal dynamic-braking transistor.
This is an important configuration detail.
The absence of an internal dynamic-braking transistor does not mean the drive cannot control a machine that decelerates.
It means that the internal switching device used for a conventional dynamic-braking resistor arrangement is not included in this particular configuration.
If the machine has substantial regenerative energy, the braking architecture must be evaluated separately.
When an electric motor decelerates, the mechanical load can return energy toward the drive.
This is particularly important for equipment with:
The returned energy can increase DC-bus voltage.
Depending on the application, the system may require:
Because the target model has no internal dynamic-braking transistor, braking requirements should be determined during the engineering stage rather than after commissioning.
The final characters of the catalog number are important when comparing related configurations.
| Feature | 20F14NF171JN0NNNNN | Braking-Enabled Configuration |
|---|---|---|
| Voltage | 690 VAC | 690 VAC |
| Normal Duty Current | 171 A | Similar high-current class |
| Normal Duty Power | 160 kW | Similar high-power class |
| Heavy Duty Current | 142 A | Similar high-current class |
| Heavy Duty Power | 132 kW | Similar high-power class |
| Frame | 7 | Frame 7 class |
| Cooling | Forced Air | Forced Air |
| Filtering | Filtered | Configuration dependent |
| CM Jumper | Installed | Configuration dependent |
| Internal Dynamic-Braking Transistor | None | Included in suitable configuration |
| HIM | Blank / No HIM | Configuration dependent |
The choice should be based on the machine’s braking requirements rather than simply choosing the highest-rated drive.
The 20F14NF171JN0NNNNN uses a Frame 7 construction.
This is a larger physical platform than the Frame 6 configurations used by many lower-current 690 VAC models.
The approximate dimensions are:
Height: 881.5 mm.
Width: 430 mm.
Depth: 349.6 mm.
Overall dimensions: approximately 881.5 × 430 × 349.6 mm.
The approximate weight range for this Frame 7 class is:
32.9–49.4 kg.

| Service Clearance | Required |
Frame 7 is considerably larger than the Frame 6 drives.
Cabinet designers should therefore consider the physical height and width before selecting the enclosure.
The drive also requires adequate room for:
The drive is specified as an IP00 / NEMA/UL Open Type unit.
This type of construction normally requires installation within a suitable industrial enclosure.
An enclosure may be selected according to the environmental conditions of the installation.
The cabinet may need to provide protection against:
For applications requiring greater enclosure protection, appropriate enclosure and conversion options should be considered during system design.
The Frame 7 open-type configuration can be converted to a more protected enclosure arrangement using a suitable enclosure kit.
This can be useful when the installation requires a different level of touch protection or enclosure configuration.
However, the enclosure rating should always be considered as a property of the complete installed system.
The cabinet itself, cable entries, ventilation openings and other components must also be suitable for the desired environmental protection level.
The 20F14NF171JN0NNNNN uses forced-air cooling.
At 160 kW Normal Duty, thermal management is one of the most important installation considerations.
The cooling system must be able to remove the heat generated by the drive during continuous operation.
The cabinet design should provide an appropriate airflow path.
Cooling openings should not be blocked by:
| Cooling Parameter | Consideration |
|---|---|
| Model | 20F14NF171JN0NNNNN |
| Cooling Method | Forced Air |
| Cabinet Ventilation | Required |
| Airflow | Must remain unobstructed |
| Cooling Fans | Require preventive maintenance |
| Cabinet Temperature | Must remain within allowable limits |
| Heat Dissipation | Must be included in cabinet design |
| Air Filters | Inspect and clean where applicable |
| Nearby Heat Sources | Must be considered |
| Service Access | Required |
The cooling system should be included in the plant’s preventive-maintenance program.
A blocked airflow path can cause unnecessary thermal stress even when the electrical load is within the drive rating.
The 20F14NF171JN0NNNNN uses a filtered configuration with the common-mode capacitor jumper installed.
This is an important part of the electrical configuration.
High-power drives should be installed with appropriate attention to:
Good cable management can help reduce unwanted electrical interference between the drive system and sensitive control equipment.
The PowerFlex 753 platform includes embedded I/O.
This allows many basic drive-control functions to be handled directly through the drive.
Typical machine-control signals may include:
Embedded I/O can reduce the need for additional external interface equipment and can simplify the electrical architecture of the machine.
The PowerFlex 753 architecture is designed to operate as part of an industrial automation system.
A typical arrangement can be:
PLC → Industrial Network → PowerFlex 753 → Motor
A more complete system may be:
HMI → PLC → Network → PowerFlex 753 → Motor → Mechanical Load
The drive can exchange operating information with the main controller.
Typical information may include:
This makes the drive suitable for large production systems in which motor control is integrated into the plant automation structure.
The PowerFlex 753 platform supports multiple motor-control approaches depending on the application and selected configuration.
Possible control methods include:
The correct control method depends on the machine.
A large centrifugal fan may not need the same control precision as a production roller.
A conveyor may require more precise acceleration and torque control.
A mixer may require strong starting torque.
A process machine may require feedback for improved speed regulation.
Large pumps are one of the most practical applications for the 20F14NF171JN0NNNNN.
Industrial pumping systems often operate at different flow requirements.
Using a variable-speed drive allows motor speed to be adjusted according to process demand.
Potential applications include:
The ability to control acceleration and operating speed can also reduce mechanical stress compared with uncontrolled starting and stopping.
Large fans can require very high motor power.
The 160 kW Normal Duty rating makes this model suitable for substantial industrial ventilation systems.
Applications may include:
The drive allows fan speed to be adjusted to actual process demand.
This can be useful when the required airflow changes throughout the production cycle.
Large blowers are commonly used in industrial processes requiring controlled airflow or pressure.
Potential applications include:
The drive can regulate blower speed and integrate the blower with the overall automation system.
Large conveyors can require very high motor torque, particularly during startup.
The 171 A Normal Duty rating and 142 A Heavy Duty rating provide substantial capacity for large conveyor systems.
Potential applications include:
Important conveyor considerations include:
Because the target configuration has no internal dynamic-braking transistor, the stopping and braking strategy should be evaluated separately.
Large rollers are common in heavy industrial production.
Applications include:
Roller systems often require coordinated motor speed.
Where multiple drives operate together, communication and feedback functions can help maintain synchronization.
Large industrial mixers can require substantial torque during startup.
The mechanical load can also change significantly as material is added, mixed or removed.
Applications include:
For high-torque mixer applications, Heavy Duty selection should be evaluated using the actual motor current rather than only the motor’s kW rating.
Agitators can have similar requirements to mixers but may operate for long periods under varying process loads.
The drive can provide adjustable speed and controlled acceleration.
Potential applications include:
The application should be evaluated for both continuous thermal load and startup torque.
Large material-handling systems can use multiple high-power motors.
The PowerFlex 753 platform is useful because each drive can be integrated into a larger control system.
Applications can include:
Multi-drive coordination can be important when several motors operate as part of the same mechanical process.
The 20F14NF171JN0NNNNN can also be used in high-power process machinery.
Potential equipment includes:
The PowerFlex 753 architecture is particularly useful when the machine requires more than simple speed control.
The 171 A Normal Duty rating is the primary advantage of this model.
It provides a substantial increase over the 142 A configuration.
This additional current capacity can be useful when the motor current is approaching the limits of a smaller drive.
The 160 kW Normal Duty rating places this model in a high-power industrial category.
It is suitable for large pumps, fans, blowers, conveyors and process equipment.
The 132 kW Heavy Duty rating provides significant capacity for demanding machinery.
This makes the drive suitable for high-torque applications that cannot be treated as simple light-load motor systems.
The 690 VAC voltage class is particularly suitable for large industrial motor systems.
It is one of the defining characteristics of this model.
The Frame 7 mechanical design provides the physical platform necessary for this level of power.
It is intended for large industrial installations rather than compact machine cabinets.
The DC input configuration provides flexibility for common-bus and DC-bus architectures.
The precharge function is important for controlled charging of the high-power DC bus.
Embedded I/O can simplify basic machine integration.
It provides a practical interface between the drive and the machine-control system.
The PowerFlex 753 platform supports modular expansion.
Depending on application requirements, additional functionality can be added through suitable options.
The drive can be integrated into PLC-based control architectures.
This makes it suitable for modern production and process-control environments.
The main advantage of the 20F14NF171JN0NNNNN is its ability to handle very large motor loads while remaining part of an expandable industrial automation platform.
A machine builder can use the PowerFlex 753 family across multiple motor sizes.
A plant can also standardize control methods and maintenance procedures around a common drive platform.
This can simplify:
System integrators often need to connect motor drives with PLCs, HMIs, sensors, feedback devices and other equipment.
The PowerFlex 753 architecture is well suited to this type of system.
The drive can serve as a dedicated motor-control node within a larger automation network.
This can help separate motor-control functions from the main PLC logic while still allowing the controller to supervise the drive.
Maintenance teams benefit from standardized equipment.
Typical maintenance tasks include:
Because this model belongs to the same PowerFlex 753 architecture as lower-current products, technicians familiar with the platform can apply similar troubleshooting principles.

The Frame 7 physical envelope is substantially larger than the Frame 6 configuration.
The approximate height of 881.5 mm is particularly important for cabinet selection.
A cabinet with insufficient vertical clearance can create problems during installation, wiring and maintenance.
The weight should also be considered when designing the cabinet mounting structure.
For transportation and lifting calculations, the actual supplied unit should be checked against its specific configuration and packaging.
The following five models are useful comparisons because they belong to the same 690 VAC PowerFlex 753 family and represent nearby power levels or closely related configurations.

These models form a useful capacity progression.
The 20F14NF098JN0NNNNN provides 90 kW Normal Duty.
The 20F14NF119JN0NNNNN provides 110 kW Normal Duty.
The 20F14NF142JN0NNNNN provides 132 kW Normal Duty.
The target 20F14NF171JN0NNNNN increases the Normal Duty rating to 160 kW.
The 20F14NF212JN0NNNNN provides a further increase to 200 kW Normal Duty.
| Model | ND Current | ND Power | HD Current | HD Power | Frame | Dynamic Braking |

| 20F14NF212JN0NNNNN | 212 A | 200 kW | 171 A | 160 kW | 7 | None |
The progression shows why the 171 A model is an important step in the PowerFlex 753 690 VAC range.
The Normal Duty rating increases from:
90 kW → 110 kW → 132 kW → 160 kW → 200 kW.
The Heavy Duty rating increases from:
75 kW → 90 kW → 110 kW → 132 kW → 160 kW.
The transition from Frame 6 to Frame 7 occurs at the 171 A configuration in this series.

| Approx. Depth | 346.4 mm | 349.6 mm |
| Weight (kg) | Approx. 38.6 | Approx. 32.9–49.4 |
This is one of the most useful comparisons for selecting the target drive.
The 171 A model provides 29 A more Normal Duty current than the 142 A model.
Normal Duty power increases from 132 kW to 160 kW.
Heavy Duty power increases from 110 kW to 132 kW.
However, the physical frame also changes from Frame 6 to Frame 7.
Therefore, the increase in electrical capacity comes with a larger mechanical installation requirement.

The target model provides a very substantial increase in power compared with the 119 A model.
Normal Duty power increases from 110 kW to 160 kW.
Heavy Duty power increases from 90 kW to 132 kW.
This makes the 171 A model a strong choice when the 119 A model is no longer sufficient.

| Weight (kg) | Approx. 32.9–49.4 | Approx. 32.9–49.4 |
The 212 A model should be considered when the motor requires more than the 171 A rating.
The target 171 A model is therefore a useful point between the 142 A and 212 A configurations.
The following models provide a broader comparison across the same brand’s drive portfolio.

The PowerFlex 753 is particularly suitable for large industrial machine control.
The PowerFlex 755 family may become more attractive when the machine requires more advanced control functionality or a more sophisticated drive architecture.
The motor should be selected according to its actual nameplate information.
Important parameters include:
| Motor Parameter | Selection Consideration |
|---|---|
| Motor Voltage | Must match the 690 VAC system |
| Motor Current | Must remain within the applicable drive rating |
| Motor Power | Compare against 160 kW ND / 132 kW HD |
| Motor Frequency | Verify required operating frequency |
| Motor Speed | Verify operating speed range |
| Starting Torque | Evaluate |
| Continuous Torque | Evaluate |
| Peak Torque | Evaluate |
| Motor Type | Confirm compatibility |
| Feedback | Determine whether encoder feedback is required |
| Braking | Evaluate regenerative energy |
| Motor Cable | Consider cable length and installation |
| Environment | Consider temperature, dust, moisture and vibration |
A 160 kW Normal Duty motor can be a logical candidate for this drive when its actual current is within the 171 A rating.
A 132 kW Heavy Duty motor can also be considered when the actual motor current and load cycle are compatible with the Heavy Duty rating.
Two motors with the same nominal kW rating can have different current requirements depending on:
For this reason, a proper drive selection should always compare the drive rating with the motor nameplate current.
The 171 A rating is the primary electrical value to consider for Normal Duty operation.
| Application | Suitability | Main Consideration |
|---|---|---|
| Large centrifugal pump | Excellent | Normal Duty |
| Large industrial fan | Excellent | Normal Duty |
| Large blower | Excellent | Airflow and pressure |
| Heavy conveyor | Excellent | Starting torque |
| Large roller | Excellent | Speed and inertia |
| Large mixer | Very Good | Breakaway torque |
| Agitator | Very Good | Torque profile |
| Process machinery | Excellent | Control integration |
| Material handling | Excellent | Acceleration and deceleration |
| High-inertia machinery | Good with appropriate braking architecture | Regenerative energy |
| Rapid-cycle machinery | Application dependent | Braking and thermal duty |
| Large production equipment | Excellent | System integration |
A typical installation can use:
PLC / Controller → Industrial Network → PowerFlex 753 → Motor → Mechanical Load
An HMI can be included:
HMI → PLC → Network → Drive → Motor
A feedback device can also be incorporated:
Encoder → Feedback Interface → Drive
Additional braking equipment can be incorporated when the machine requires controlled dissipation of regenerative energy.
| Industry | Typical Applications |
|---|---|
| Mining | Large conveyors and material handling |
| Metals | Rollers and heavy process machinery |
| Paper | Rollers and production lines |
| Chemical Processing | Pumps, mixers and agitators |
| Water Treatment | Large pumps and blowers |
| Manufacturing | Production machinery |
| Food Processing | Mixers and conveyors |
| Industrial HVAC | Large fans and blowers |
| Utilities | Pumps and auxiliary systems |
| Material Handling | Conveyors and transfer systems |
| General Process Industry | Pumps, fans, blowers and mixers |
The physical size of the Frame 7 drive should be considered at the beginning of cabinet design.
The approximate dimensions are:
881.5 mm high × 430 mm wide × 349.6 mm deep.
The approximate weight range is:
32.9–49.4 kg.
This means the cabinet must have sufficient structural strength.
The drive should also have sufficient clearance for:
A cabinet should not be fabricated with only the drive’s external dimensions in mind.
The surrounding service area is equally important.
Thermal design becomes especially important at 160 kW.
The drive produces heat during normal operation.
The cabinet designer should consider:
If multiple drives are installed in the same cabinet, their combined heat load must be considered.
The drive should not be placed immediately next to another large heat-producing component without evaluating the resulting thermal conditions.
The electrical installation should consider:
Because the drive is a high-power 690 VAC product, electrical installation should be performed according to the applicable industrial electrical requirements and the actual installation documentation.
Regular preventive maintenance can include:
Dust accumulation is especially important because it can restrict airflow and increase thermal stress.
Loose electrical connections can also create localized heating.
Regular inspection therefore contributes significantly to long-term reliability.

The five models provide a useful progression from 90 kW to 200 kW Normal Duty.
For a motor around 90 kW, the 98 A model can be considered.
For approximately 110 kW, the 119 A model is a logical option.
For approximately 132 kW, the 142 A model becomes appropriate.
For approximately 160 kW, the target 171 A model provides the required capacity.
For approximately 200 kW, the 212 A configuration should be considered.

These five models are useful for comparing different product positions within the same brand.
The PowerFlex 525 products are much smaller and are generally suited to compact machines.
The PowerFlex 753 is intended for larger industrial systems.
The PowerFlex 755 is aimed toward more advanced industrial control applications.
The 690 VAC target model is in a substantially higher power class than these 480 VAC examples.

| Larger than 160 kW ND | Consider the next higher current class |
The 171 A model is an important point in the 690 VAC PowerFlex 753 range because it moves into Frame 7.
The electrical capacity increases to:
171 A Normal Duty.
160 kW Normal Duty.
142 A Heavy Duty.
132 kW Heavy Duty.
This makes it suitable for larger motors than the 142 A Frame 6 model.
At the same time, the larger Frame 7 construction means the cabinet design must change accordingly.
Frame 7 provides the physical structure required for higher current capacity.
The larger frame provides room for:
For this reason, the transition from Frame 6 to Frame 7 should be considered both an electrical and mechanical design change.
For a large fan, conveyor, roller or rotating machine, stopping behavior can be just as important as starting behavior.
The stored energy of a large rotating system can be considerable.
A short deceleration time can cause significant regenerative energy.
The application engineer should therefore determine:
The absence of an internal braking transistor in the JN configuration makes this analysis particularly important.
For centrifugal pumps and fans, the machine may not require aggressive braking.
In such applications, the JN configuration can be attractive because the drive provides the required high-power motor control without including an internal dynamic-braking transistor.
The drive can adjust motor speed according to process demand.
This can provide a more flexible operating point than running the motor continuously at full speed.
For conveyors, the high current rating provides useful starting and operating capacity.
The drive can provide:
For very heavy conveyors, the mechanical load and braking requirements must still be evaluated separately.
Process machinery can benefit from the combination of high power and automation integration.
The drive can be part of a larger system involving:
This allows the motor to become part of the overall production process instead of operating as an isolated electrical device.

The 20F14NF171JN0NNNNN is a high-power PowerFlex 753 industrial AC drive designed for large three-phase motor applications.
Its principal rating is 171 A Normal Duty, corresponding to 160 kW Normal Duty.
Its Heavy Duty rating is 142 A / 132 kW.
This makes it a substantial step above the 142 A / 132 kW Normal Duty configuration.
The 690 VAC voltage class makes the drive particularly suitable for large industrial motor systems.
The Frame 7 construction provides the mechanical platform necessary for this level of electrical capacity.
The approximate physical dimensions are 881.5 × 430 × 349.6 mm.
The approximate product weight is in the 32.9–49.4 kg range, depending on the exact Frame 7 configuration.
The open-type construction means that an appropriate industrial enclosure should be provided.
The forced-air cooling system also makes cabinet thermal design an important part of the installation.
The DC input with precharge configuration provides flexibility for common-bus and DC-bus applications.
The filtered configuration and installed common-mode capacitor jumper should be considered when designing the complete electrical system.
Embedded I/O simplifies basic machine integration.
The expandable PowerFlex 753 architecture also allows communication, feedback and other application-specific functions to be incorporated where required.
One of the most important details of this exact catalog number is the absence of an internal dynamic-braking transistor.
This is not necessarily a disadvantage.
For pumps, fans, blowers and other applications where aggressive braking is not required, the JN configuration can be a practical choice.
For high-inertia equipment with rapid stopping requirements, the braking system should be engineered separately.
The target model is particularly well suited to:
The most important selection criteria are the 171 A Normal Duty current rating, 160 kW Normal Duty rating, 142 A Heavy Duty current rating, 132 kW Heavy Duty rating, 690 VAC three-phase voltage class, and Frame 7 mechanical configuration.
For a 160 kW Normal Duty motor, the model is a strong candidate when the actual motor nameplate current and application conditions are within the drive rating.
For a 132 kW Heavy Duty motor, it can also be an appropriate selection when the operating cycle, torque requirements and motor current are compatible with the Heavy Duty rating.
The larger Frame 7 dimensions should be considered carefully during cabinet design.
The approximate 881.5 × 430 × 349.6 mm physical envelope is significantly larger than the Frame 6 models below it in the PowerFlex 753 690 VAC range.
The approximate 32.9–49.4 kg weight range should also be considered when designing the cabinet mounting structure, transportation arrangement and installation procedure.
Overall, the 20F14NF171JN0NNNNN can be summarized as a 690 VAC, three-phase, 171 A, 160 kW Normal Duty / 132 kW Heavy Duty, Frame 7, forced-air-cooled PowerFlex 753 industrial AC drive with DC input and precharge, filtered configuration, common-mode capacitor jumper installed, embedded I/O, standard protection, blank/no-HIM configuration and no internal dynamic-braking transistor.
Its combination of high current capacity, high motor-power capability, 690 VAC operation, expandable architecture and industrial automation integration makes it a strong solution for large motor-driven systems.
For applications requiring approximately 160 kW Normal Duty or 132 kW Heavy Duty, the 20F14NF171JN0NNNNN is a particularly important model to consider within the 690 VAC PowerFlex 753 family.
