5. Electrical Rating

The 212 A output-current rating is the defining electrical characteristic of this model.

At the 690 VAC voltage class, the drive is intended for large industrial motors and high-capacity rotating machinery.

The drive provides two principal motor-duty ratings:

• Normal Duty: 200 kW
• Heavy Duty: 160 kW

The difference between these ratings is important during drive selection.

Normal Duty is generally used for applications where the motor load and overload requirements are comparatively moderate.

Heavy Duty is intended for applications where the motor experiences greater torque demand, more severe acceleration requirements, heavier cyclic loading, or higher overload conditions.

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

---

6. Normal Duty and Heavy Duty

Rating Category	Specification
Model	20G1ANF212JN0NNNNN
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 industrial equipment such as pumps, fans, blowers, conveyors, process machines, and material-handling equipment.

The 160 kW Heavy Duty rating provides a separate rating for applications that impose greater electrical and thermal stress on the drive.

When a motor operates with frequent overload, repeated acceleration, high starting torque, or demanding load cycles, the Heavy Duty rating should be considered during system selection.

---

7. 690 VAC Three-Phase Operation

The 20G1ANF212JN0NNNNN is designed for 690 VAC three-phase industrial systems.

The 690 V class is commonly used in large industrial installations where substantial motor power is required.

Using a higher motor voltage allows high power to be transmitted at a comparatively lower current than would be required by an equivalent lower-voltage motor system.

This can be useful when designing:

• Large motor feeders.
• Industrial switchgear.
• Motor control centers.
• High-power pump stations.
• Large conveyor systems.
• Mining equipment.
• Industrial process machinery.

The actual facility supply voltage and motor voltage must be confirmed before installation.

---

8. Frame 7 Construction

The drive uses a Frame 7 power section.

Frame 7 is intended for high-power PowerFlex 755 applications and provides a larger electrical and mechanical structure for the higher current range.

The Frame 7 design accommodates the power components, cooling requirements, wiring connections, and physical clearances necessary for a 212 A high-power drive.

Because of its size and power rating, cabinet design should provide sufficient space for:

• Power wiring.
• Motor wiring.
• Control wiring.
• Ethernet communication cables.
• Cooling airflow.
• Fan access.
• Grounding connections.
• Maintenance work.
• Component replacement.

---

9. Dimensions and Weight

The approximate dimensions for the Frame 7 open-type construction are:

Height: 881.5 mm

Width: 430 mm

Depth: 349.6 mm

The approximate weight is in the range of 72.6 to 108.9 kg, depending on the specific Frame 7 configuration and associated hardware.

This is an important correction compared with smaller Frame 6 PowerFlex 755 units. A Frame 7 high-power drive should not be treated as a 40–50 kg class unit when planning transportation or cabinet installation.

Mechanical Parameter	Specification
Model	20G1ANF212JN0NNNNN
Frame	Frame 7
Height	Approx. 881.5 mm
Width	Approx. 430 mm
Depth	Approx. 349.6 mm
Overall Dimensions	Approx. 881.5 × 430 × 349.6 mm
Net Weight	Approx. 72.6–108.9 kg
Weight Unit	kg
Enclosure	IP20/IP00 Open Type
Cooling	Forced Air
Installation	Cabinet / Panel
Service Clearance	Required
Airflow Clearance	Required

The exact shipping weight can be higher than the equipment weight because packaging, mounting hardware, accessories, and other components may be included.

For cabinet fabrication and mechanical handling, the actual configuration drawing and equipment documentation should be used as the final dimensional reference.

---

10. AC Input with Precharge

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

The precharge arrangement controls the initial charging of the internal DC bus capacitors when the drive is energized.

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

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

The absence of external DC terminals means that this model is not configured as a dedicated external common-DC-bus connection model.

---

11. Dynamic Braking Configuration

The 20G1ANF212JN0NNNNN is specified with:

Dynamic Braking: None

This means the JN configuration does not include the internal dynamic-braking transistor found in the corresponding JA configuration.

This distinction is important when selecting a drive for high-inertia loads.

Applications that require rapid deceleration may need an alternative drive configuration or a separately engineered braking solution.

Typical applications where braking requirements should be evaluated carefully include:

• High-inertia conveyors.
• Centrifuges.
• Large rotating machinery.
• Rapid-cycle production equipment.
• Certain material-handling machines.
• High-speed machinery.
• Equipment requiring frequent stop/start cycles.

For applications where the internal DB transistor is required, the corresponding 20G1ANF212JA0NNNNN should be considered instead.

---

12. JN Versus JA Configuration

The following table highlights the main difference between the two configurations.

Feature	JN Configuration	JA Configuration
Model Example	20G1ANF212JN0NNNNN	20G1ANF212JA0NNNNN
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	None	DB Transistor
HIM	Blank / No HIM	Blank / No HIM
Embedded EtherNet/IP	Yes	Yes

The electrical power rating is essentially the same between the two configurations.

The major functional difference is the dynamic-braking hardware.

---

13. Filtered Configuration

The 20G1ANF212JN0NNNNN uses a filtered configuration with the CM jumper installed.

This arrangement is useful for industrial systems where electromagnetic compatibility and common-mode electrical behavior need to be considered.

The filtering arrangement can be beneficial in systems containing:

• Multiple AC drives.
• Long motor cables.
• Sensitive instrumentation.
• PLC equipment.
• Industrial Ethernet equipment.
• Analog measurement equipment.
• Process-control systems.
• Other electronic equipment installed within the same electrical environment.

Filtering is only one part of a complete EMC installation.

Correct grounding, motor-cable routing, shielding, cabinet bonding, and installation practices remain important.

---

14. Embedded EtherNet/IP Communication

The drive includes embedded EtherNet/IP communication.

This allows the 20G1ANF212JN0NNNNN to communicate with industrial control systems without requiring the basic drive architecture to depend entirely on a separate communication module.

Typical network functions include:

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

This is particularly useful in large installations containing many drives that need to be coordinated from a central automation system.

---

15. Blank / No HIM Configuration

The drive is supplied as Blank / No HIM.

HIM means Human Interface Module.

A no-HIM configuration is appropriate when the drive is expected to operate as part of a centralized automation system.

Instead of using a local keypad, operators can interact with the drive through:

• PLC systems.
• HMI systems.
• SCADA systems.
• Industrial Ethernet.
• Central control stations.
• Supervisory systems.

This configuration can be especially convenient in large drive cabinets where local operator interfaces are not required on every individual drive.

---

16. Product Introduction

The 20G1ANF212JN0NNNNN is a high-power PowerFlex 755 AC drive intended for large industrial motor applications.

Its 212 A output-current capability places it in the high-capacity section of the 690 VAC PowerFlex 755 range.

With approximately 200 kW Normal Duty capability and 160 kW Heavy Duty capability, the drive can control substantial industrial motors used in continuous-process and material-handling applications.

The Frame 7 construction provides the physical and thermal platform necessary for this current class.

The forced-air cooling system removes heat from the power electronics and supports continuous industrial operation when the installation environment and cooling system are correctly designed.

The embedded EtherNet/IP interface allows the drive to become part of a centralized automation architecture.

The JN configuration does not include an internal dynamic-braking transistor, making it important to evaluate braking requirements separately when selecting this model.

---

32. JN Configuration Advantages

The JN configuration has several practical characteristics.

First, it provides the same basic high-power 690 VAC platform as the corresponding JA configuration while omitting the internal dynamic-braking transistor.

This can be appropriate for applications where the motor and mechanical load do not require the internal braking function.

The configuration also includes:

• 690 VAC operation.
• 212 A output current.
• 200 kW Normal Duty.
• 160 kW Heavy Duty.
• Frame 7 construction.
• Forced-air cooling.
• Filtered configuration.
• CM jumper installed.
• Embedded EtherNet/IP.
• AC input with precharge.
• No external DC terminals.
• Blank/no HIM.

---

33. Applications Where the JN Configuration Can Be Appropriate

The JN configuration can be considered for applications where controlled variable-speed operation is required but the internal dynamic-braking transistor is not part of the drive requirement.

Typical examples can include:

Centrifugal Pumps

Pump loads often have predictable deceleration characteristics and may not require aggressive braking.

Large Fans

Large fans can often be allowed to decelerate naturally or according to a controlled ramp.

Process Blowers

Blower systems may prioritize continuous speed control and process regulation over rapid stopping.

Continuous Conveyors

Where the mechanical system has a long controlled stopping time, the absence of an internal DB transistor may be acceptable.

Cooling Systems

Large cooling pumps and fans can use variable-speed control without requiring frequent aggressive braking.

The actual application should always be evaluated for regenerative energy and stopping requirements.

---

34. When to Consider the JA Configuration

The corresponding JA model can be considered when an internal dynamic-braking transistor is required.

Applications with:

• High-inertia loads.
• Frequent deceleration.
• Rapid stopping.
• High-speed rotation.
• Short stopping times.
• Repeated braking cycles.

may require additional braking capability.

The Allen-Bradley 20G1ANF212JN0NNNNN is a high-capacity PowerFlex 755 AC variable frequency drive designed for large industrial motor-control applications.

Its main electrical specifications are 690 VAC, three-phase operation, 212 A output current, 200 kW Normal Duty, and 160 kW Heavy Duty.

The drive uses a Frame 7 construction with forced-air cooling and an IP20/IP00 open-type design.

The approximate physical dimensions are 881.5 × 430 × 349.6 mm, and the approximate equipment weight is 72.6–108.9 kg depending on configuration.

The model includes embedded EtherNet/IP, making it suitable for integration with PLC, HMI, SCADA, and other industrial automation systems.

It also uses a filtered configuration with the CM jumper installed, providing an appropriate configuration for industrial EMC considerations when combined with correct grounding, cabling, and cabinet practices.

The most important characteristic distinguishing this model from the corresponding JA version is its dynamic-braking configuration.

The 20G1ANF212JN0NNNNN does not include the internal dynamic-braking transistor.

For applications that do not require internal dynamic braking, this configuration provides a high-power 690 VAC drive platform with a 212 A output rating.

For applications requiring the internal braking transistor, the corresponding 20G1ANF212JA0NNNNN provides the same principal voltage, current, and power class with the different braking configuration.

Typical applications for the 20G1ANF212JN0NNNNN include large pumps, industrial fans, blowers, conveyors, water-treatment equipment, mining machinery, material-handling systems, process machinery, and other large rotating industrial equipment.

The closely related 690 VAC models include 20G1ANF119JN0NNNNN, 20G1ANF142JN0NNNNN, 20G1ANF171JN0NNNNN, 20G1ANF263JN0NNNNN, and the corresponding 20G1ANF212JA0NNNNN configuration.

For a large 690 VAC motor installation requiring approximately 212 A output current and up to 200 kW Normal Duty, the 20G1ANF212JN0NNNNN provides a high-power Frame 7 platform with network communication, forced-air cooling, filtered configuration, and cabinet-based industrial installation capability.
