5. Electrical Rating

The 212 A output-current rating is the main electrical characteristic of this drive.

At the 690 VAC voltage class, the drive is designed for large industrial motors and high-capacity mechanical equipment.

The drive provides approximately:

• 200 kW Normal Duty
• 160 kW Heavy Duty

The two duty ratings allow the drive to be applied to different types of motor loads.

Normal Duty is generally associated with applications where the motor operates with comparatively moderate overload requirements.

Heavy Duty is intended for applications with greater torque demand, more demanding acceleration, higher cyclic loading, or more severe overload conditions.

The actual motor full-load current should always be checked against the applicable drive current rating during engineering selection.

---

6. Normal Duty and Heavy Duty Ratings

Rating	Specification
Model	20G1ANF212JA0NNNNN
Voltage	690 VAC
Output Current	212 A
Normal Duty	200 kW
Heavy Duty	160 kW
Frame	Frame 7
Cooling	Forced Air
Phase	Three Phase

The 200 kW Normal Duty rating makes this drive suitable for large pumps, fans, blowers, conveyors, process machinery, material-handling equipment, and other high-power rotating equipment.

The 160 kW Heavy Duty rating provides a lower motor-power classification because heavy-duty operation places greater thermal and electrical demands on the drive.

When the application involves frequent starting and stopping, high acceleration torque, rapid load changes, or high-inertia machinery, the Heavy Duty rating should be used as an important selection reference.

---

7. 690 VAC Three-Phase Operation

The 20G1ANF212JA0NNNNN is designed for a 690 VAC three-phase industrial power system.

The 690 V class is commonly used in larger industrial installations where substantial motor power needs to be transmitted and controlled.

For the same approximate power level, a higher motor voltage allows the operating current to remain lower than it would be on a lower-voltage system.

This can be beneficial when designing large motor installations, switchgear systems, motor feeders, and industrial control cabinets.

The actual incoming power system should always be checked against the drive’s specified voltage range and installation requirements.

---

8. Frame 7 Construction

The 20G1ANF212JA0NNNNN uses a Frame 7 power section.

Frame 7 is intended for high-power PowerFlex 755 applications and provides a larger mechanical and thermal platform than the smaller frame configurations.

The larger frame accommodates the power electronics and cooling requirements associated with the 212 A current class.

For cabinet design, sufficient room should be allowed for:

• Drive installation.
• Power cable routing.
• Control wiring.
• Cooling airflow.
• Maintenance access.
• Fan service.
• Electrical clearances.
• Grounding connections.
• Removal and replacement of major components.

---

9. Dimensions and Weight

The physical dimensions of this model are suitable for high-power industrial cabinet installations.

The approximate mechanical dimensions are:

Height: 881.5 mm

Width: 430 mm

Depth: 349.6 mm

Weight: approximately 48 kg

Mechanical Parameter	Specification
Model	20G1ANF212JA0NNNNN
Frame	Frame 7
Height	Approx. 881.5 mm
Width	Approx. 430 mm
Depth	Approx. 349.6 mm
Overall Size	Approx. 881.5 × 430 × 349.6 mm
Net Weight	Approx. 48 kg
Enclosure	IP20/IP00 Open Type

Installation	Cabinet / Panel
Service Clearance	Required
Airflow Clearance	Required

The stated dimensions and weight should be treated as equipment-reference values. Final cabinet design should allow additional space for wiring, ventilation, cable bending radius, service access, and any installation accessories.

---

10. AC Input with Precharge

The model uses an AC input with precharge and no DC terminals.

The precharge system controls the initial charging process of the drive’s internal DC bus capacitors when the drive is energized.

This is particularly important for high-power equipment because the internal DC bus contains substantial stored energy.

The configuration is intended primarily for conventional AC-fed motor-drive systems.

The absence of external DC terminals also distinguishes this configuration from certain PowerFlex 755 variants designed specifically for different DC-bus arrangements.

---

11. Dynamic Braking Capability

One of the most important characteristics of the JA configuration is the presence of an internal dynamic-braking transistor.

The 20G1ANF212JA0NNNNN includes a DB transistor.

Dynamic braking is useful when a motor needs to decelerate more rapidly than would normally occur through natural mechanical deceleration.

During deceleration, the motor can return energy toward the drive’s DC bus. A dynamic-braking system can manage this energy and dissipate it through an appropriate braking resistor arrangement.

This is particularly useful for applications involving:

• High-inertia loads.
• Rapid stopping.
• Frequent acceleration and deceleration.
• Large conveyors.
• Centrifuges.
• Material-handling equipment.
• Unwinders and winders.
• Large rotating machinery.
• Hoisting-related machinery where the overall drive architecture permits its use.

The internal DB transistor does not mean that every application automatically has a complete braking-resistor system.

The external braking resistor and associated system design must be selected according to the actual regenerative energy, stopping time, duty cycle, and application requirements.

---

12. JA Versus JN Configuration

The corresponding JN model provides a useful comparison.

Feature	JA Configuration	JN Configuration
Model Example	20G1ANF212JA0NNNNN	20G1ANF212JN0NNNNN
Voltage	690 VAC	690 VAC
Output Current	212 A	212 A
Normal Duty	200 kW	200 kW
Heavy Duty	160 kW	160 kW
Frame	Frame 7	Frame 7
Cooling	Forced Air	Forced Air
Filtering	Filtered	Filtered
CM Jumper	Installed	Installed
Dynamic Braking	DB Transistor	None
HIM	Blank / No HIM	Blank / No HIM
EtherNet/IP	Embedded	Embedded

The principal difference is the dynamic-braking configuration.

For an application where an internal braking transistor is required, the JA configuration is the relevant configuration to evaluate.

For applications where dynamic braking is not required, the corresponding JN configuration may be considered.

---

13. Embedded EtherNet/IP

The drive includes embedded EtherNet/IP communication.

This allows the drive to be integrated directly into a networked industrial control architecture.

Typical communication functions can include:

• Start and stop commands.
• Speed reference.
• Frequency reference.
• Motor current monitoring.
• Motor speed monitoring.
• Drive status.
• Fault status.
• Alarm information.
• Parameter access.
• Diagnostic information.
• PLC control.
• HMI monitoring.
• Supervisory control.
• Production data collection.

The integrated communication capability is particularly useful in plants where multiple variable-frequency drives need to be controlled from a central automation system.

---

14. No HIM Configuration

The model is supplied as Blank / No HIM.

HIM means Human Interface Module.

A no-HIM configuration is often appropriate when the drive is installed in a centralized control cabinet and operators interact with the equipment through a PLC, HMI, SCADA system, or industrial Ethernet network.

This configuration also reduces the need for a local operator keypad on the front of every drive.

If local operator adjustment is required, a compatible human-interface solution can be added according to the system design.

---

15. Filtered Configuration

The 20G1ANF212JA0NNNNN is specified with a filtered configuration and CM jumper installed.

This arrangement is useful in industrial environments where electromagnetic compatibility and common-mode electrical behavior are important design considerations.

Filtering can be beneficial in installations containing:

• Multiple variable-frequency drives.
• Long motor cables.
• Sensitive control equipment.
• Instrumentation systems.
• Industrial Ethernet equipment.
• PLC systems.
• Analog measurement equipment.
• Other electronic equipment installed in the same electrical environment.

Correct grounding and motor-cable practices remain essential.

The drive filter should not be considered a substitute for proper cabinet grounding, cable shielding, cable routing, and system-level EMC engineering.

---

16. Product Introduction

The 20G1ANF212JA0NNNNN is a high-capacity industrial AC drive intended for large motor applications.

With a 212 A current rating and 200 kW Normal Duty capability, it is positioned toward the high-power end of the PowerFlex 755 family.

The combination of 690 VAC operation and Frame 7 construction makes the drive suitable for large industrial equipment where motor power and system voltage are considerably higher than those found in small machine applications.

The integrated EtherNet/IP interface allows the drive to become part of a larger automation system instead of functioning as an isolated motor controller.

The internal dynamic-braking transistor further expands the range of applications by providing a drive configuration suitable for systems where controlled braking and energy management during deceleration are required.

---

---

17.7 Forced-Air Cooling

Forced-air cooling provides the airflow needed to remove heat generated by the high-power switching components.

For reliable operation, cabinet airflow and environmental conditions must be managed correctly.

---

17.8 Industrial Open-Type Construction

20. Installation Considerations

Because the 20G1ANF212JA0NNNNN is an IP20/IP00 open-type drive, it should normally be installed inside a suitable electrical cabinet or protected industrial enclosure.

The installation environment should provide appropriate protection from excessive dust, moisture, corrosive substances, and other contaminants.

Adequate airflow is particularly important because the drive uses forced-air cooling.

The cabinet should provide sufficient clearance around the drive so that cooling air can move through the equipment without excessive restriction.

Important installation factors include:

• Input power protection.
• Proper grounding.
• Motor cable selection.
• Motor cable routing.
• Control cable routing.
• EtherNet/IP cable installation.
• Cabinet ventilation.
• Cooling fan access.
• Service clearance.
• Environmental protection.
• EMC considerations.
• Braking resistor installation where required.

---

21. Dynamic Braking Application Considerations

The JA configuration is particularly useful when the motor must decelerate quickly.

When a high-inertia load slows down, mechanical energy is transferred back through the motor into the drive system.

Without an appropriate energy-management method, the DC-bus voltage can rise during aggressive deceleration.

A properly engineered dynamic-braking system can dissipate this energy through a braking resistor.

Typical applications that may require such capability include:

• Large conveyors.
• High-speed rotating equipment.
• Centrifugal machinery.
• Large fans with substantial inertia.
• Material-handling equipment.
• Machines with frequent stop/start cycles.
• Certain hoisting-related systems.

The braking resistor must be correctly sized for the application.

Important factors include:

• Motor power.
• Motor speed.
• Load inertia.
• Deceleration time.
• Number of braking cycles.
• Braking frequency.
• Ambient temperature.
• Resistor duty rating.

The internal DB transistor provides the switching capability, while the complete braking system must still be engineered according to the actual application.

---

22. Maintenance Considerations

Routine inspection is important for high-power variable-frequency drives.

The cooling system should be inspected periodically to ensure that airflow is not restricted.

Dust accumulation can reduce cooling performance and increase the operating temperature of the power electronics.

Recommended maintenance activities include:

• Inspecting cooling fans.
• Checking ventilation openings.
• Inspecting power connections.
• Checking control wiring.
• Inspecting grounding connections.
• Reviewing drive fault history.
• Monitoring abnormal temperature conditions.
• Inspecting the cabinet for contamination.
• Checking Ethernet communication.
• Inspecting braking components where installed.
• Checking motor cable connections.

Regular maintenance helps reduce unexpected downtime and can improve the service life of the overall drive system.

---

32. Cabinet Design Considerations

The physical dimensions of approximately 881.5 × 430 × 349.6 mm should be considered when designing the control cabinet.

The cabinet should provide more space than the basic drive dimensions alone.

Additional space may be necessary for:

• Incoming power cables.
• Motor output cables.
• Control wiring.
• Ethernet communication cables.
• Grounding conductors.
• Braking-resistor connections.
• Cooling airflow.
• Cable bends.
• Maintenance access.
• Fan replacement.
• Electrical inspection.
• Safe working clearance.

The drive should not be installed in a cabinet where surrounding components significantly restrict airflow.

---

33. Environmental Considerations

Important environmental factors include:

• Ambient temperature.
• Dust.
• Humidity.
• Condensation.
• Corrosive gases.
• Airborne particles.
• Cooling-air quality.
• Vibration.
• Cabinet ventilation.
• Altitude.

Where the drive is installed in a harsh environment, cabinet design should provide suitable environmental protection.

The open-type construction should not be treated as equivalent to a sealed outdoor enclosure.

---

The Allen-Bradley 20G1ANF212JA0NNNNN is a high-power PowerFlex 755 AC variable frequency drive designed for large industrial motor-control applications.

Its primary electrical characteristics are 690 VAC three-phase input, 212 A output current, 200 kW Normal Duty capacity, and 160 kW Heavy Duty capacity.

The drive uses a Frame 7 construction with forced-air cooling and an open-type IP20/IP00 design intended for integration into an industrial electrical cabinet.

Its approximate physical dimensions are 881.5 mm high × 430 mm wide × 349.6 mm deep, with an approximate equipment weight of 48 kg.

One of the defining characteristics of the JA configuration is the internal dynamic-braking transistor.

This makes the 20G1ANF212JA0NNNNN particularly relevant to high-power machinery where controlled deceleration and management of regenerative energy are important design requirements.

The drive also includes embedded EtherNet/IP communication, allowing it to be integrated into PLC-controlled production systems, HMI platforms, supervisory systems, and larger industrial automation networks.

Its filtered configuration and installed CM jumper provide a suitable foundation for industrial EMC considerations, while proper grounding, motor-cable routing, shielding, and cabinet design remain important parts of the complete installation.

Typical applications include large pumps, fans, blowers, conveyors, mining equipment, material-handling machinery, water-treatment systems, process machinery, and other large rotating industrial equipment.

Within the same 690 VAC family, the 20G1ANF142JA0NNNNN, 20G1ANF171JA0NNNNN, 20G1ANF263JA0NNNNN, and 20G1ANF212JN0NNNNN provide useful alternatives depending on current capacity and dynamic-braking requirements.

For applications requiring approximately 212 A of output current, up to 200 kW Normal Duty, and an internal dynamic-braking transistor, the 20G1ANF212JA0NNNNN represents a high-capacity Frame 7 configuration intended for demanding industrial motor-control systems.
