3. Model Number

20G1ANF263JA0NNNNN

This model belongs to the high-power 690 V section of the PowerFlex 755 family.

The 263 A current class places this drive toward the upper end of the Frame 7 range for conventional 690 V PowerFlex 755 applications.

The 250 kW Normal Duty rating makes it suitable for applications where the motor normally operates with relatively stable load requirements, while the 200 kW Heavy Duty rating provides a lower power rating for applications requiring greater overload capability.

The JA configuration is particularly important because it combines the filtered configuration with the installed common-mode capacitor jumper and an internal dynamic braking transistor.

This makes the model different from the corresponding JN configuration, where the internal dynamic braking transistor is not included.

5. Normal Duty and Heavy Duty Ratings

The 20G1ANF263JA0NNNNN provides two primary power ratings: 250 kW Normal Duty and 200 kW Heavy Duty.

Normal Duty operation is generally associated with applications where the motor load is relatively stable and overload requirements are moderate. Typical examples include many large pumps, fans, blowers, and process machines.

Heavy Duty operation is intended for applications where the motor may experience higher starting torque, greater load variation, or more frequent overload conditions.

Duty Rating	Power Rating	Typical Application Characteristics
Normal Duty	250 kW	Pumps, fans, blowers, compressors, conveyors and relatively stable loads
Heavy Duty	200 kW	Conveyors, mixers, crushers, process machinery and higher-load applications

The actual motor selection should always consider motor nameplate current, starting requirements, load profile, ambient temperature, installation method, and required overload capacity rather than selecting the drive only from the motor’s kW value.

---

6. Dimensions and Weight

Because this is a Frame 7 high-power drive, the physical size is substantially larger than the Frame 6 models in the same voltage family.

Mechanical Parameter	Specification
Model	20G1ANF263JA0NNNNN
Frame Size	Frame 7
Height	Approx. 881.5 mm
Width	Approx. 430.0 mm
Depth	Approx. 349.6 mm
Approx. Weight	72.6–108.9 kg
Cooling	Forced Air
Installation	Vertical cabinet/panel installation
Enclosure	Open Type
Protection Class	IP20/IP00

The weight range should be treated as configuration-dependent. Final shipping weight and installed weight can vary depending on the selected hardware, accessories, mounting arrangement, control components, and other configuration details.

For cabinet design, adequate clearance should be provided around the drive for ventilation, cable routing, inspection, and maintenance.

The cabinet should also be designed to handle the mechanical weight of a Frame 7 drive and the thermal load produced during continuous operation.

---

7. Product Introduction

The PowerFlex 755 family is designed for large industrial motor-control applications requiring more than simple variable-speed operation.

The 20G1ANF263JA0NNNNN combines high-voltage motor control with network communication, configurable control functions, diagnostics, and industrial automation integration.

Its 690 VAC rating is especially useful in high-power installations because higher motor voltage can allow high-power motors to operate with lower current than equivalent lower-voltage systems.

The 263 A output-current class gives the drive the capacity to control large motors used in industrial production equipment, pumping systems, material handling equipment, process lines, fans, blowers, and other heavy machinery.

The Frame 7 design provides the physical and thermal platform required for this high-power rating.

Forced-air cooling allows heat generated by the power section to be removed efficiently when the drive is installed correctly inside a suitable electrical cabinet.

---

8. Embedded EtherNet/IP

One of the major features of the 20G1ANF263JA0NNNNN is its embedded EtherNet/IP communication capability.

This allows the drive to become part of an industrial Ethernet-based control system without requiring the same type of external communication arrangement that would be necessary with a drive lacking integrated network communication.

Typical network functions include:

• Drive command control.
• Speed reference transmission.
• Start and stop control.
• Status monitoring.
• Fault and alarm information.
• Drive parameter access.
• Motor operating data.
• Diagnostic information.
• Integration with PLC-based automation systems.

For large industrial systems, network integration can significantly simplify the exchange of operating information between the drive, controller, HMI, SCADA system, and other automation equipment.

---

9. Dynamic Braking

The JA configuration includes an internal dynamic braking transistor.

This is an important feature when the driven machine needs controlled deceleration or when the motor can regenerate energy during rapid speed reduction.

During regenerative operation, the motor can return electrical energy toward the drive DC bus. A dynamic braking system can be used to dissipate excess regenerative energy through an appropriate braking resistor arrangement.

Typical applications that may benefit from dynamic braking include:

• High-inertia fans.
• Large conveyors.
• Centrifuges.
• Material handling equipment.
• Hoisting-related machinery where applicable.
• Large rotating process equipment.
• Machines requiring relatively short stopping times.

The internal braking transistor does not mean that every application automatically has a complete braking system. The braking resistor, resistor sizing, duty cycle, thermal capacity, wiring, and control settings must still be selected according to the machine’s actual regenerative energy requirements.

---

10. Filtering and CM Jumper Configuration

The 20G1ANF263JA0NNNNN uses the filtered configuration with the CM jumper installed.

This configuration is useful in installations where attention must be given to conducted electrical noise, electromagnetic compatibility, and the overall grounding arrangement.

The common-mode capacitor configuration should always be considered together with the motor cable, motor grounding, cabinet grounding, line conditions, and the requirements of the complete electrical installation.

Proper installation practices are particularly important with high-power drives because the physical scale of the system also increases the significance of cable routing, grounding, shielding, and electromagnetic compatibility.

---

11. Cooling System

The 20G1ANF263JA0NNNNN uses forced-air cooling.

The cooling system is essential because a high-power variable frequency drive generates heat in the power semiconductors, switching components, bus components, control circuits, and associated power electronics.

The installation cabinet should therefore provide suitable airflow.

Important installation considerations include:

• Adequate cabinet ventilation.
• Correct air intake and exhaust arrangement.
• Avoiding blockage of cooling passages.
• Maintaining appropriate ambient conditions.
• Keeping dust accumulation under control.
• Providing sufficient space around the drive.
• Preventing hot exhaust air from being recirculated into the drive intake.

For high-power Frame 7 equipment, thermal management should be considered during the initial cabinet design rather than being treated as a secondary installation issue.

---

12. Main Applications

The 20G1ANF263JA0NNNNN is suitable for many large industrial machines.

Large Pumping Systems

The drive can be used for large process pumps, water pumps, cooling-water pumps, circulation pumps, and industrial fluid-handling systems.

Variable-speed operation allows the motor speed to be adjusted according to process demand rather than operating continuously at full speed.

This can provide improved process control and may reduce unnecessary energy consumption in suitable variable-torque applications.

---

Fans and Blowers

Large fans and blowers are common applications for high-power 690 V drives.

Examples include:

• Industrial ventilation fans.
• Furnace fans.
• Boiler-related fans.
• Cooling tower fans.
• Exhaust systems.
• Dust collection equipment.
• Large air-handling systems.

The 250 kW Normal Duty rating provides a suitable capacity range for many large fan and blower installations.

---

Conveyors

Large conveyors can require significant starting torque and stable speed control.

The drive can regulate conveyor speed, coordinate acceleration and deceleration, and communicate operating conditions to the plant automation system.

Applications may include:

• Mining conveyors.
• Bulk material conveyors.
• Cement handling systems.
• Aggregate processing.
• Warehouse material handling.
• Industrial production lines.

---

Mixers and Agitators

---

Process Machinery

The drive can also be applied to large process machines where precise speed regulation and centralized monitoring are required.

Possible applications include:

• Production machinery.
• Processing lines.
• Industrial machine systems.
• Large rotating equipment.
• Material processing equipment.
• Industrial automation systems.

---

Compressors and High-Power Rotating Equipment

High-power compressors and other large rotating machines can require substantial motor capacity.

The 20G1ANF263JA0NNNNN provides a 690 V, 263 A platform that can be considered for large motor-control applications when the motor current and duty requirements fall within the drive’s specified ratings.

---

13. Product Advantages

13.1 High 690 V Power Capability

The 690 V class makes this drive suitable for high-power industrial systems.

For large motors, higher operating voltage can help reduce current compared with lower-voltage arrangements at the same power level.

This can be beneficial when designing motor cables, switchgear, transformers, and overall power distribution systems.

---

13.2 263 A Output Capacity

The 263 A output-current rating places the 20G1ANF263JA0NNNNN in a high-capacity section of the PowerFlex 755 family.

It is intended for substantially larger motors than the lower-current Frame 6 models.

---

13.3 250 kW Normal Duty Rating

The 250 kW Normal Duty rating provides a substantial power range for large industrial machines.

This is particularly relevant for variable-torque applications such as pumps and fans, as well as other machines operating under relatively stable load conditions.

---

13.4 200 kW Heavy Duty Rating

The 200 kW Heavy Duty rating provides a separate rating for applications where the machine has more demanding load characteristics.

This allows engineers to select the drive according to the actual operating duty instead of relying only on the motor’s nominal power.

---

13.5 Internal Dynamic Braking Transistor

The built-in dynamic braking transistor is a significant advantage for applications requiring controlled deceleration or handling of regenerative energy.

It can simplify the overall braking architecture compared with a configuration that does not include the internal braking transistor, although the braking resistor and complete braking circuit still need to be correctly engineered.

---

13.6 Embedded EtherNet/IP

Embedded EtherNet/IP provides a convenient method for integrating the drive into industrial automation systems.

This is useful for systems where drive control, monitoring, alarms, diagnostics, and process information need to be exchanged over an industrial Ethernet network.

---

13.7 Flexible Industrial Control

The PowerFlex 755 platform is designed for more than basic frequency adjustment.

It can support sophisticated motor-control strategies and system-level control requirements, making it suitable for machinery where stable speed regulation, acceleration control, deceleration control, and monitoring are important.

---

13.8 Suitable for Large Industrial Cabinets

The Frame 7 structure is intended for high-power applications and can be incorporated into larger motor-control centers, automation cabinets, electrical rooms, and dedicated drive cabinets.

The open-type design gives system designers flexibility in selecting the final cabinet arrangement.

The cabinet must have sufficient physical space for the drive body, incoming power cables, motor cables, control wiring, network connections, grounding conductors, and any braking equipment.

Thermal design is equally important.

The drive’s forced-air cooling system requires appropriate air circulation, and the cabinet should prevent hot air from circulating repeatedly through the drive.

Cable routing should also be planned carefully.

High-current motor and input cables should be routed in a manner that supports good electrical practice and minimizes unnecessary interference with low-level control and communication wiring.

The cabinet should also provide convenient access for inspection and maintenance.

---

23. Why the 20G1ANF263JA0NNNNN Is Used for Large Industrial Systems
