Allen-Bradley 20F1ANF212AN0NNNNN — Detailed Product Specifications, Introduction, Applications, Advantages and Related Models

1. Product Overview

The 20F1ANF212AN0NNNNN is a high-power PowerFlex 753 AC drive designed for large three-phase industrial motor applications.

It is rated for 690 VAC, three-phase input, with a 212 A Normal Duty rating, 200 kW Normal Duty power rating, and 160 kW Heavy Duty rating.

The drive uses a Frame 7 construction and forced-air cooling. It is an open-type industrial drive intended to be installed inside a suitable electrical cabinet or enclosure.

A particularly important characteristic of this exact catalog number is the configuration of its braking and filtering options.

The 20F1ANF212AN0NNNNN does not have an internal dynamic-braking transistor. The catalog configuration also uses an EMC filter with the common-mode capacitor jumper removed.

This means the model should not be confused with closely related versions that include an internal braking transistor or a different common-mode capacitor configuration.

The drive is intended for large industrial applications such as pumps, fans, blowers, conveyors, compressors, mixers and other high-power motor-driven machinery.

---

3. Detailed Technical Parameters

The physical dimensions above correspond to the Frame 7 construction used by this power class.

The actual shipping or installed weight can vary with the exact hardware configuration, accessories and construction, so the 72.6–108.9 kg figure should be treated as an engineering-range value rather than a guaranteed shipping weight for every configuration.

---

4. Product Description

The 20F1ANF212AN0NNNNN is a large industrial variable frequency drive designed to control the speed and torque of three-phase AC motors.

Instead of connecting the motor directly to a fixed-frequency electrical supply, the drive controls the electrical output supplied to the motor.

This allows the motor speed to be adjusted according to the process requirement.

For example, a large pump may need full speed during peak demand but only partial speed during normal operation.

The drive can reduce motor speed rather than keeping the motor at full speed continuously.

The same principle can be used for large fans, blowers, conveyors, mixers and other industrial machinery.

The drive also provides controlled acceleration and deceleration, which can reduce mechanical shock compared with direct-on-line starting.

---

5. 212 A Current Rating

The 212 A current rating places this model in the high-power section of the PowerFlex 753 range.

The two main operating ratings are:

The 200 kW Normal Duty rating is particularly useful for suitable variable-torque applications.

The 160 kW Heavy Duty rating provides a lower power rating for applications with more demanding torque and overload requirements.

Motor selection should always be based on the actual motor nameplate current and application duty rather than relying only on the motor’s kW rating.

---

6. Normal Duty Operation

The 200 kW Normal Duty rating is well suited to applications where the motor load generally follows a variable-torque characteristic.

Typical examples include:

• Centrifugal pumps.
• Centrifugal fans.
• Large blowers.
• HVAC systems.
• Cooling-water pumps.
• Industrial ventilation.
• Water-treatment equipment.
• Circulation systems.

These applications can benefit from variable-speed operation because the process does not always require maximum motor output.

---

7. Heavy Duty Operation

The Heavy Duty rating is approximately:

171 A / 160 kW

This rating is more appropriate for demanding applications where the motor experiences greater torque requirements.

Typical applications can include:

• Heavy conveyors.
• Mixers.
• Material-handling machinery.
• Certain compressors.
• Processing machinery.
• Large industrial machines.
• Constant-torque applications.

The actual machine load profile should always be evaluated before deciding whether Normal Duty or Heavy Duty is appropriate.

---

8. Dynamic Braking Configuration

One of the most important characteristics of 20F1ANF212AN0NNNNN is that it has:

No internal dynamic-braking transistor.

This is an important distinction when comparing it with other PowerFlex 753 catalog numbers.

During normal motor deceleration, the drive can reduce motor speed according to the programmed deceleration ramp.

However, when a high-inertia load decelerates rapidly, the motor can regenerate electrical energy back toward the drive.

That regenerative energy can increase the DC-bus voltage.

Because this particular model does not contain the internal braking transistor, applications requiring substantial dynamic braking need a different braking arrangement or a different drive configuration.

---

9. Applications Where No Internal Braking Is Suitable

The lack of an internal dynamic-braking transistor is not necessarily a disadvantage.

It can be perfectly suitable for applications where the motor does not need rapid stopping.

Typical examples include:

• Large centrifugal pumps.
• Large fans.
• Industrial blowers.
• Cooling systems.
• HVAC equipment.
• Water circulation systems.
• Some process pumps.

For these applications, a relatively long deceleration ramp may be acceptable.

The motor can gradually reduce speed without requiring large amounts of regenerative energy to be dissipated.

---

10. Applications Requiring Special Braking Consideration

Additional braking engineering should be considered for:

• High-inertia conveyors.
• Cranes.
• Hoists.
• Centrifuges.
• Large flywheel systems.
• Rapid stopping machinery.
• Unwinders.
• Rewinders.
• Heavy rollers.
• Machines requiring frequent deceleration.

If the machine requires substantial dynamic braking, a braking-enabled configuration should be evaluated instead.

A suitable braking resistor and complete braking circuit must be selected according to the actual regenerative energy and duty cycle.

---

11. Filtering Configuration

The model uses an EMC filter.

This is an important part of the electrical configuration.

Industrial variable frequency drives can generate high-frequency electrical noise because of their high-speed switching operation.

An appropriate EMC/filtering arrangement can help manage conducted and radiated electrical interference.

However, the filter does not eliminate the need for proper installation practices.

The complete system should still pay attention to:

• Grounding.
• Cable routing.
• Motor cable length.
• Shielding.
• Control cable separation.
• Cabinet bonding.
• Motor-frame grounding.
• Power cable arrangement.

---

12. Common-Mode Capacitor Jumper

The configuration of the common-mode capacitor jumper is another important distinction in the catalog number.

For 20F1ANF212AN0NNNNN, the configuration uses the A option in this position, meaning the common-mode capacitor jumper is removed.

This is different from related configurations where the jumper is installed.

This distinction matters when the drive is installed in systems with specific grounding arrangements.

It is therefore important to match the complete catalog number when replacing an existing drive.

---

13. Product Applications

13.1 Large Centrifugal Pumps

Large centrifugal pumps are among the most suitable applications for this drive.

Typical applications include:

• Water treatment.
• Industrial water circulation.
• Cooling-water systems.
• Process-water systems.
• Large pumping stations.
• Industrial fluid transfer.
• Irrigation systems.

The drive can adjust pump speed to match flow and pressure requirements.

When combined with PID control and appropriate process feedback, the drive can automatically adjust speed to maintain a desired process setpoint.

---

14. Industrial Fans

Large fans can consume significant electrical power when operating continuously.

The drive can adjust fan speed according to actual airflow requirements.

Potential applications include:

• Factory ventilation.
• Industrial exhaust.
• Furnace ventilation.
• Cooling systems.
• Dust extraction.
• Large HVAC installations.
• Process ventilation.

Reducing fan speed during periods of lower demand can improve process efficiency.

---

15. Industrial Blowers

The drive is also suitable for large blower applications.

Examples include:

• Wastewater aeration.
• Combustion air.
• Pneumatic conveying.
• Process air.
• Dust collection.
• Industrial drying.
• Ventilation.

A variable-speed blower can respond more closely to actual process requirements than a fixed-speed blower.

---

16. Large Conveyors

The 212 A current capacity allows the drive to control large conveyor motors.

Potential applications include:

• Mining conveyors.
• Bulk material handling.
• Industrial production lines.
• Aggregate handling.
• Heavy manufacturing.
• Transfer systems.

Controlled acceleration can reduce mechanical shock on the conveyor.

This can help reduce stress on:

• Gearboxes.
• Belts.
• Couplings.
• Bearings.
• Shafts.
• Drive pulleys.

However, because this exact model has no internal braking transistor, conveyor stopping requirements should be evaluated carefully.

---

17. Mixers

Large industrial mixers can require considerable torque.

The Heavy Duty rating of 160 kW / 171 A provides substantial capacity for many large mixer applications.

Possible applications include:

• Chemical processing.
• Cement processing.
• Industrial blending.
• Material mixing.
• Food processing.
• Large agitators.

The actual starting torque and load characteristics should be checked before final selection.

---

18. Compressors

The drive can also be used for suitable large compressor applications.

Variable-speed operation can be useful when compressor demand changes during production.

Important selection factors include:

• Compressor type.
• Motor current.
• Motor voltage.
• Starting torque.
• Operating speed range.
• Minimum speed.
• Maximum speed.
• Acceleration.
• Deceleration.

Compressor applications should therefore be evaluated on a machine-by-machine basis.

---

19. Industrial Process Equipment

The drive can be integrated into a wide range of process machinery.

Examples include:

• Large material-processing machines.
• Production lines.
• Industrial rollers.
• Large agitators.
• Processing pumps.
• Cooling systems.
• Industrial air systems.

The ability to adjust motor speed can make it easier to match motor output to changing production requirements.

---

20. Main Product Advantages

20.1 High-Power 690 VAC Operation

The 690 VAC class makes the drive suitable for large industrial electrical systems.

It is intended for applications where smaller low-power drives are no longer appropriate.

---

20.2 212 A Current Capacity

The 212 A current class provides substantial motor-control capability.

This allows the drive to handle large industrial motors within its applicable duty ratings.

---

20.3 200 kW Normal Duty

The 200 kW Normal Duty rating makes the drive particularly attractive for large variable-torque applications.

This includes pumps, fans and blowers.

---

20.4 160 kW Heavy Duty

The 160 kW Heavy Duty rating extends the drive into more demanding industrial applications.

It can therefore be considered for suitable conveyors, mixers and process machinery.

---

20.5 Embedded I/O

Embedded I/O simplifies integration with external machine-control circuits.

This can reduce the amount of additional basic I/O hardware required.

---

20.6 PID Capability

PID control is valuable for process applications.

It can be used for:

• Pressure control.
• Flow control.
• Fan pressure.
• Temperature-related control.
• Process regulation.

This makes the drive particularly useful for pumps and fans.

---

20.7 EMC Filter

The EMC filter provides a useful electrical configuration for applications where electromagnetic compatibility needs to be considered.

The final system still requires proper grounding and cable installation.

---

20.8 No Unnecessary Braking Hardware

For applications that do not require dynamic braking, the absence of an internal braking transistor can be a reasonable configuration.

Large pumps and fans often do not require aggressive deceleration.

---

21. Dimensions and Weight

The physical size of this drive is important for cabinet design.

Because the drive is physically large and can weigh substantially more than 70 kg, the cabinet structure needs to be designed accordingly.

Lifting, transportation and maintenance access should also be considered.

---

22. Cabinet Installation

The drive is an open-type product rather than a complete standalone outdoor enclosure.

It therefore needs to be installed inside an appropriate electrical enclosure or cabinet.

The cabinet should provide adequate room for:

• Power cables.
• Control wiring.
• Cable bending radius.
• Ventilation.
• Heat dissipation.
• Grounding.
• Protective devices.
• Maintenance access.

The cabinet should also be able to support the mechanical weight of the drive.

---

23. Cooling Requirements

The drive uses forced-air cooling.

High-power variable frequency drives generate substantial heat.

The cabinet design therefore needs to consider the total heat load.

Important factors include:

• Ambient temperature.
• Cabinet temperature.
• Airflow.
• Fan operation.
• Air inlet conditions.
• Air outlet conditions.
• Dust accumulation.
• Installation altitude.
• Other equipment inside the cabinet.

Poor ventilation can cause unnecessary thermal stress.

---

24. Motor Selection

The drive should be selected based on the actual motor nameplate.

Important motor information includes:

The motor’s rated current should be checked before selecting the final drive.

---

25. Normal Duty vs. Heavy Duty

---

26. Five Recommended Same-Series or Closely Related Models

The following models are useful when comparing this drive with other PowerFlex 753 configurations.

20F1ANF171JN0NNNNN

This is a lower-capacity alternative in the same 690 VAC PowerFlex 753 family.

It provides approximately 171 A / 160 kW Normal Duty and 142 A / 132 kW Heavy Duty.

It is useful when the motor current is below the 212 A class.

---

20F1ANF212JN0NNNNN

This is the closest currently active configuration to the target in terms of electrical rating.

It maintains:

• 690 VAC.
• 212 A.
• 200 kW ND.
• 160 kW HD.
• Frame 7.

The important difference is the filtering/common-mode capacitor configuration.

---

20F1ANF263JN0NNNNN

This model increases the capacity to approximately:

263 A Normal Duty

250 kW Normal Duty

212 A Heavy Duty

200 kW Heavy Duty

It is a logical choice for a larger motor system.

---

20F1ANF212JA0NNNNN

This is an especially important comparison model.

It has essentially the same power and current class as the target, but it includes an internal dynamic-braking transistor.

It is therefore more suitable when the application requires a braking resistor arrangement.

---

20F1ANF171JA0NNNNN

This is a lower-current version with an internal braking transistor.

It can be considered when the application needs braking but does not require the full 212 A capacity.

---

27. Five Popular Same-Brand Models

The PowerFlex 755 models are the closest alternatives when the application requires high-power industrial motor control.

The PowerFlex 525 models are much smaller and should not be regarded as direct replacements for the 20F1ANF212AN0NNNNN.

They are included because they are widely used models within the same brand portfolio and cover a different range of motor sizes.

---

28. PowerFlex 753 vs. PowerFlex 755

For conventional high-power applications, the PowerFlex 753 is a strong choice.

For applications involving more advanced control, feedback or coordinated motion, the PowerFlex 755 family can be considered.

---

29. Application Suitability

---

30. Energy-Saving Potential

Variable-speed control can provide significant energy-saving opportunities in suitable applications.

The greatest opportunities are usually associated with centrifugal loads.

Examples include:

• Centrifugal pumps.
• Centrifugal fans.
• Blowers.

If a pump or fan does not need full output, the drive can reduce motor speed.

This can be more efficient than continuously operating the motor at full speed and controlling the process through mechanical restriction.

The actual energy-saving result depends on the equipment and operating profile.

Important factors include:

• Annual operating hours.
• Average load.
• Required flow.
• Required pressure.
• Motor efficiency.
• Pump efficiency.
• Fan efficiency.
• Operating speed.

A proper energy study should therefore use actual operating conditions.

---

31. Mechanical Advantages

The drive can also provide mechanical benefits.

Controlled acceleration can reduce sudden mechanical loading.

This can reduce stress on:

• Gearboxes.
• Belts.
• Couplings.
• Bearings.
• Shafts.
• Conveyor components.
• Pump systems.

Controlled acceleration can be particularly valuable for large machines where direct starting produces a sudden torque shock.

---

32. Process-Control Advantages

The drive can provide more than simple motor-speed control.

It can form part of a process-control system.

For example:

Pressure Sensor → PID Control → Drive → Pump

or:

Air Pressure Sensor → PID Control → Drive → Blower

or:

Temperature Control → Drive → Fan

This allows the motor speed to respond automatically to changing process conditions.

---

33. Electrical Installation Considerations

Because this is a high-power 690 VAC drive, electrical installation should be planned carefully.

Important areas include:

• Input protection.
• Disconnect equipment.
• Grounding.
• Motor cable selection.
• Control cable routing.
• EMC considerations.
• Cabinet bonding.
• Motor grounding.
• Short-circuit protection.
• Cable termination.
• Thermal management.

The final installation should always be designed according to the actual electrical system and applicable engineering requirements.

---

34. Motor Cable Considerations

The motor cable is an important part of a VFD installation.

High-frequency switching can produce electrical noise and voltage stress.

The installation should therefore consider:

• Cable type.
• Cable length.
• Shielding.
• Grounding.
• Motor insulation.
• Cable routing.
• Separation from sensitive control cables.

The exact motor-cable requirements depend on the installation.

---

35. Replacement Considerations

If the 20F1ANF212AN0NNNNN is being used as a replacement part, the entire catalog number should be checked.

Do not replace the drive based only on:

690 VAC + 212 A + 200 kW

because other configuration details can be different.

In particular, check:

• Dynamic braking.
• EMC filter.
• CM jumper configuration.
• I/O.
• HIM.
• Enclosure.
• Communication modules.
• Safety functions.
• Existing motor parameters.

The filtering and common-mode capacitor configuration can be especially important in a replacement installation.

---

36. Difference Between 20F1ANF212AN0NNNNN and 20F1ANF212JN0NNNNN

This is a good example of why the complete catalog number matters.

The two drives have very similar power ratings, but the filtering/common-mode configuration is different.

---

37. Difference Between 20F1ANF212AN0NNNNN and 20F1ANF212JA0NNNNN

This is probably the most important comparison when selecting between closely related catalog numbers.

---

38. Recommended Model Selection

---

39. Important Lifecycle Information

The 20F1ANF212AN0NNNNN is a discontinued configuration.

For projects involving an existing installation, this means the catalog number may be encountered primarily in installed equipment, replacement inventories, refurbished equipment or legacy systems.

A related replacement configuration is available in the same PowerFlex 753 family.

When replacing an older unit, it is important to check the complete configuration rather than selecting a replacement only by voltage and power.

This is particularly important because the original model has a specific EMC filter and CM jumper arrangement and does not have an internal dynamic-braking transistor.

---

40. Overall Product Evaluation

The 20F1ANF212AN0NNNNN is a high-power industrial AC drive designed for large three-phase motor systems.

Its key electrical ratings are:

690 VAC

212 A Normal Duty

200 kW Normal Duty

171 A Heavy Duty

160 kW Heavy Duty

The Frame 7 construction provides the physical capacity required for this power level.

The drive is especially suitable for large pumps, fans, blowers and other industrial machines that require variable-speed operation without requiring an internal dynamic-braking transistor.

The EMC filter and CM-jumper-removed configuration are also important when matching the drive to the electrical grounding and noise-control strategy of an existing system.

43. Final Conclusion

The 20F1ANF212AN0NNNNN is a high-capacity Allen-Bradley PowerFlex 753 Frame 7 AC drive designed for large three-phase industrial motors.

Its 212 A Normal Duty rating and 200 kW Normal Duty capacity make it suitable for large variable-speed applications, while its 171 A / 160 kW Heavy Duty rating gives it additional capability for demanding industrial loads.

The most important feature of this exact configuration is that it does not include an internal dynamic-braking transistor.

That makes it a particularly sensible configuration for applications such as large pumps, fans, blowers and other machines where controlled acceleration and deceleration are required but aggressive dynamic braking is not part of the application.

The drive also uses an EMC filter with the common-mode capacitor jumper removed.

This configuration should be matched carefully to the grounding and EMC requirements of the installation, especially when the unit is being used as a replacement for an existing drive.

Physically, it is a substantial Frame 7 drive, with approximate dimensions of 881.5 × 430 × 349.6 mm and an approximate weight range of 72.6–108.9 kg.

Because of its size and weight, cabinet construction, ventilation, lifting, cable routing and maintenance access should all be considered during installation.

For a lower-capacity application, the 20F1ANF171JN0NNNNN is a natural alternative.

For the same 212 A / 200 kW class with the CM jumper installed, the 20F1ANF212JN0NNNNN is a closely related option.

For applications where internal dynamic braking is required, the 20F1ANF212JA0NNNNN is the more appropriate configuration to evaluate.

For applications requiring still greater capacity, the 20F1ANF263JN0NNNNN moves into the approximately 263 A / 250 kW Normal Duty class.

Overall, the 20F1ANF212AN0NNNNN is best understood as a large 690 VAC, 212 A, 200 kW Normal Duty PowerFlex 753 drive with Frame 7 construction, forced-air cooling, embedded I/O, EMC filtering, CM jumper removed and no internal dynamic-braking transistor, making it a strong fit for large industrial variable-speed motor systems where those specific configuration characteristics match the application.
