20G11JC1K0AN0NNNNN — Detailed Product Profile and Technical Specification

The 20G11JC1K0AN0NNNNN is a large-capacity industrial AC drive from the PowerFlex 755 series. It is designed for high-power three-phase motor applications where substantial current capacity, variable-speed control, industrial networking, enclosed construction and centralized automation are required.

This particular configuration is a 400 VAC, three-phase, air-cooled, Frame 9 drive with an output current rating of approximately 1,040 A. Its published power ratings are approximately 630 kW light duty, 560 kW normal duty and 500 kW heavy duty.

The model is substantially larger than the 22–55 kW drives commonly used for individual machines. It belongs to the high-power end of the PowerFlex 755 range and is intended for large industrial equipment, process systems and high-power motor applications.

---

1. Brand, Series and Product Classification

---

2. Product Introduction

The 20G11JC1K0AN0NNNNN is designed for applications where the motor power requirement is far beyond the range of small or medium-sized industrial inverters.

With a rated current of approximately 1,040 A, the drive is intended for very large motors and heavy industrial equipment.

The 560 kW normal-duty rating makes it appropriate for continuous industrial applications where the motor operates with a conventional load profile.

The drive also provides a 500 kW heavy-duty rating, which is relevant when the application requires increased overload capability and more demanding acceleration or torque characteristics.

A 630 kW light-duty rating is also associated with this configuration, making the drive suitable for certain variable-torque or lighter-load applications.

The model therefore provides three different application capacity levels depending on the load profile.

---

3. Power Rating Structure

The difference between these ratings is important.

A 630 kW light-duty application generally has different overload requirements from a 500 kW heavy-duty application.

For engineering selection, the motor’s actual rated current, torque requirement, acceleration time, duty cycle, overload profile and mechanical load should be considered.

---

4. Detailed Electrical Parameters

---

5. Mechanical Construction

This model is fundamentally different from smaller panel-mounted drives.

The 20G11JC1K0AN0NNNNN is configured as an 800 mm deep MCC-style cabinet arrangement.

It is therefore intended to be integrated into a larger electrical distribution or motor-control environment rather than mounted like a small standalone inverter.

For this particular high-power MCC-style configuration, it is important not to treat the drive itself as a small standalone component.

The 800 mm depth describes the MCC-style cabinet configuration. The complete height, width and installed weight can depend on the exact cabinet arrangement, incoming/outgoing section, bus configuration and other equipment included in the assembly.

Therefore, unlike the smaller Frame 5 drives, it would be inappropriate to assign a single exact overall cabinet weight without the specific mechanical configuration.

---

6. Important Note About Dimensions and Weight

For engineering purposes, the most useful confirmed mechanical characteristic of this catalog configuration is its 800 mm deep MCC-style construction.

The total installed assembly is substantially different from a small individual drive module.

The final cabinet dimensions and total weight can be influenced by:

• MCC section configuration.
• Busbar arrangement.
• Incoming power equipment.
• Output connections.
• Disconnect equipment.
• Auxiliary control equipment.
• Cooling equipment.
• Cabinet construction.
• Cable-entry arrangement.
• Optional accessories.

For this reason, the dimensions and weight should be treated as configuration-dependent rather than using an artificially precise number.

For a replacement or cabinet-layout project, the actual mechanical drawing for the exact assembly should be used.

---

7. Enclosure and Environmental Protection

The model uses an IP54 / NEMA Type 12 industrial enclosure configuration.

This provides considerably more environmental protection than an open-frame drive.

The enclosure is suitable for many indoor industrial environments where dust and incidental moisture protection are required.

The installation environment should nevertheless be evaluated carefully.

---

8. Embedded EtherNet/IP Communication

The drive includes embedded EtherNet/IP communication.

This is especially important for a high-power drive because large motors are often integrated into centralized process-control systems.

A typical architecture can be represented as:

PLC / DCS / Controller

↓

Industrial Ethernet

↓

20G11JC1K0AN0NNNNN

↓

Large Industrial Motor

↓

Pump / Fan / Conveyor / Compressor / Process Machine

The drive can exchange control and diagnostic information with the control system.

This allows the drive to become part of a larger automated production or process system.

---

9. Dynamic Braking Configuration

The catalog configuration specifies:

Dynamic Braking: None

This is an important distinction from smaller PowerFlex 755 configurations that may contain an internal braking transistor.

The absence of an internal dynamic-braking transistor means that the system should not be designed assuming the drive itself provides an integrated braking transistor.

If the application requires rapid deceleration or regenerative-energy management, the complete braking strategy should be evaluated separately.

Possible system-level approaches may include:

• Controlled deceleration.
• External braking equipment where applicable.
• Regenerative power handling.
• Mechanical braking.
• Process-specific stopping methods.

For very large motors, braking energy can be substantial, so braking should be engineered as a complete system rather than treated as a simple drive accessory.

---

10. EMC Configuration

The model is configured with an EMC filter.

The CM jumper is removed in this configuration.

This is relevant when considering grounding, common-mode current and electromagnetic compatibility.

Large-power drives require careful installation because the electrical energy and cable dimensions are considerably greater than those associated with small drives.

Important installation considerations include:

• Protective grounding.
• Cabinet bonding.
• Motor-cable routing.
• Cable shielding.
• Grounding of motor frames.
• Separation between control and power cables.
• Communication-cable routing.
• Proper termination.
• Cabinet grounding.
• Appropriate installation of filters and reactors where required.

---

11. No-HIM Configuration

The catalog configuration is specified as:

Blank / No HIM

This means there is no local Human Interface Module included as part of the basic catalog configuration.

This is particularly suitable for large industrial installations where the operator interface is normally located at a central control station.

A typical system may use:

DCS / PLC → Ethernet → Drive

with the operator interacting through:

HMI / SCADA → Control System → Drive

This arrangement is common for large process systems.

---

12. Main Product Advantages

---

13. Application — Large Pumps

Large industrial pumps can require hundreds of kilowatts of motor power.

The 20G11JC1K0AN0NNNNN is suitable for applications where a large pump motor requires variable-speed operation.

Potential applications include:

• Water-transfer pumps.
• Industrial process pumps.
• Cooling-water systems.
• Large circulation systems.
• Water-treatment processes.
• Petrochemical process systems.
• Mining water systems.
• Large-scale industrial fluid systems.

Variable-speed control allows the pump motor to operate according to process demand.

---

14. Application — Large Fans and Blowers

Large industrial fans and blowers can require very substantial motor power.

Typical applications include:

• Large ventilation systems.
• Industrial exhaust.
• Process-air systems.
• Furnace ventilation.
• Large cooling systems.
• Dust-collection systems.
• Industrial air-handling systems.

The ability to adjust motor speed allows the process to operate according to actual airflow requirements.

---

15. Application — Large Conveyors

High-capacity conveyor systems are another important application area.

Large conveyors may be used in:

• Mining.
• Bulk-material handling.
• Cement production.
• Steel processing.
• Aggregate handling.
• Port facilities.
• Large manufacturing plants.

The drive can provide controlled acceleration and speed regulation.

For long conveyors, multiple motors and drives may also need to operate together.

The integrated communication capability can be useful in coordinating such systems.

---

16. Application — Mining Equipment

Large mining machines often use motors in the hundreds-of-kilowatts range.

Potential applications include:

• Conveyor systems.
• Crushing systems.
• Material handling.
• Large fans.
• Pumping systems.
• Processing machinery.
• Ore-handling equipment.

The high current capacity makes this drive suitable for applications where smaller industrial drives are not adequate.

---

17. Application — Cement and Bulk Material Processing

Cement and bulk-material facilities can contain many high-power motors.

Potential applications include:

• Large conveyors.
• Crushers.
• Fans.
• Blowers.
• Mills.
• Material-processing machinery.
• Large pumps.
• Dust-collection equipment.

The 500–630 kW range makes this model relevant to the larger motors used in such environments.

---

18. Application — Steel and Metal Processing

Large metal-processing facilities may require substantial motor power for:

• Rolling equipment.
• Material handling.
• Large fans.
• Pumps.
• Process lines.
• Cooling systems.
• Auxiliary machinery.

Variable-speed control can help coordinate motor speed with production requirements.

---

19. Application — Process Industries

The drive is also suitable for large process installations.

Potential industries include:

• Chemical processing.
• Water treatment.
• Mining.
• Cement.
• Steel.
• Pulp and paper.
• Large-scale manufacturing.
• Bulk material processing.

The embedded network interface makes the drive suitable for integration with centralized process-control systems.

---

20. Motor Control

The PowerFlex 755 platform is intended for advanced industrial motor control.

Depending on motor type, feedback configuration and application requirements, the platform can support different control methods.

Potential control approaches include:

• V/Hz control.
• Sensorless vector control.
• Vector control.
• Closed-loop speed control.
• Torque-oriented control.
• Feedback-based control.

The exact control strategy should be selected according to the motor and machine requirements.

---

21. Feedback and Expansion Capability

Large process machinery may require feedback from encoders or other sensors.

The PowerFlex 755 architecture supports expansion through compatible option modules.

This flexibility is useful when the drive is integrated into a complex industrial control system.

---

22. High-Power Electrical Installation

A 1,040 A-class drive requires substantially different installation practices from a small 10–50 A inverter.

The electrical system should consider:

• Incoming cable or busbar sizing.
• Short-circuit protection.
• Disconnect equipment.
• Grounding.
• Motor cable sizing.
• Cabinet ventilation.
• Heat dissipation.
• Harmonic considerations.
• Power quality.
• EMC.
• Transformer capacity.
• Motor starting characteristics.
• Emergency stopping requirements.

The incoming power system should be designed according to the actual drive configuration and applicable electrical standards.

---

23. Thermal Management

At approximately 560 kW normal-duty power, thermal management is a major design consideration.

The drive uses forced-air cooling.

The cabinet and surrounding installation must provide sufficient airflow to remove heat generated by the power electronics.

Important factors include:

• Ambient temperature.
• Cabinet temperature.
• Cooling fan capacity.
• Air inlet temperature.
• Air outlet temperature.
• Airflow restrictions.
• Installation altitude.
• Continuous current.
• Overload cycle.
• Other heat-generating equipment.

A large drive should never be installed in a cabinet without considering the total thermal load.

---

24. Mechanical Installation

Because the model uses an 800 mm deep MCC-style cabinet configuration, the installation should be treated as a complete electrical enclosure system.

---

25. Dimensions and Weight

Because this model is an 800 mm deep MCC-style packaged drive, the dimensions should be handled differently from a conventional standalone drive.

The 800 mm depth is the key mechanical characteristic that can be stated for the catalog configuration.

The exact height, width and total weight depend on the complete MCC-style assembly.

This is particularly important because a large packaged drive may contain cabinet components beyond the power-conversion section itself.

---

26. Five Same-Series or Closely Related Models

The following five models are suitable comparison choices within the high-power PowerFlex 755 range.

These models are all positioned in the high-power range.

The 20G11JC1K0AN0NNNNN occupies a useful middle position between approximately 910 A and the larger 1,090 A, 1,175 A and 1,465 A configurations.

---

27. High-Power Series Comparison

---

28. Why Choose the 1,040 A Model?

The 20G11JC1K0AN0NNNNN is useful when the application falls around the 500–560 kW operating range.

A smaller 910 A-class drive may not provide sufficient normal-duty capacity for a 560 kW application.

At the same time, moving to a much larger 1,090 A or 1,175 A drive may provide additional capacity that is unnecessary for the actual motor.

The 1,040 A model therefore occupies an important position in the high-power selection range.

---

29. Five Popular Models from the Same Brand

The following models represent different capacity levels and product families.

These models represent very different application levels.

The compact PowerFlex 525 models are intended for much smaller machinery, whereas the PowerFlex 755 Frame 9 model is designed for very large industrial motors.

32. Advantages in Large Industrial Systems

High Current Capacity

The 1,040 A output rating is the defining characteristic of this model.

It allows the drive to be used with motors requiring very large current capacity.

This makes it suitable for applications far beyond the range of ordinary machine-building inverters.

---

560 kW Normal-Duty Capacity

The 560 kW normal-duty rating makes this drive suitable for large continuous industrial loads.

Potential applications include:

• Large pumps.
• Large fans.
• Conveyors.
• Processing equipment.
• Mining machinery.
• Material-handling equipment.
• Industrial production lines.

---

500 kW Heavy-Duty Capacity

The heavy-duty rating is 500 kW.

This is important for applications where the motor experiences higher torque requirements or more demanding operating cycles.

---

630 kW Light-Duty Capacity

The 630 kW light-duty rating provides additional capacity for appropriate variable-torque applications.

This can be relevant to large fan and pump systems.

---

33. Advantages for Process Automation

The integrated EtherNet/IP interface makes the drive suitable for process automation.

A large process system may contain dozens or even hundreds of motors.

Using networked drives allows the control system to monitor:

• Motor speed.
• Motor current.
• Drive status.
• Faults.
• Alarms.
• Operating conditions.
• Production states.

This reduces the need for extensive individual hardwired signals.

---

34. Advantages for Centralized Control

The no-HIM configuration is particularly appropriate for centralized systems.

The drive can be operated from:

• PLC.
• DCS.
• HMI.
• SCADA.
• Central control room.

This is often preferable for large industrial equipment where the drive cabinet is physically distant from the operator.

---

35. Advantages for Large Motor Applications

A large motor requires more than simple speed adjustment.

The complete drive system must handle:

• High input current.
• High output current.
• Thermal loading.
• Large motor cables.
• Electromagnetic effects.
• Grounding.
• Mechanical inertia.
• Acceleration.
• Deceleration.
• Fault protection.
• Communication.

The Frame 9 architecture is designed around this type of high-power industrial environment.

---

36. Maintenance and Service Considerations

Large drives require a more structured maintenance approach than compact drives.

Recommended inspection areas include:

Because the drive operates at very high current, loose or poorly maintained power connections can create substantial heat.

Maintenance procedures should therefore be carried out according to the appropriate electrical safety procedures.

---

37. Motor Selection Considerations

The motor should be matched according to actual electrical requirements.

At this power level, motor current and system design are especially important.

A motor rated at 560 kW should not automatically be paired with this drive without checking the actual motor nameplate current and operating conditions.

---

38. High-Power Application Considerations

When applying a 560 kW-class drive, engineers should evaluate:

• Transformer capacity.
• Short-circuit current.
• Harmonic distortion.
• Power factor.
• Incoming disconnect.
• Semiconductor protection.
• Motor cable size.
• Motor insulation.
• Grounding.
• EMC.
• Cooling.
• Cabinet heat dissipation.
• Mechanical load inertia.
• Acceleration time.
• Deceleration time.
• Emergency stopping.
• Process safety.
• Maintenance access.

These considerations are considerably more important at 1,040 A than they are for a small 10 A drive.

40. Overall Product Assessment

The 20G11JC1K0AN0NNNNN is a high-power member of the PowerFlex 755 series and is designed for industrial systems where motor power reaches the several-hundred-kilowatt range.

Its principal electrical rating is 1,040 A at 400 VAC three-phase, with 630 kW light-duty, 560 kW normal-duty and 500 kW heavy-duty capacity.

This makes it fundamentally different from the smaller 37 kW and 45 kW configurations.

The drive is particularly appropriate for large pumps, fans, blowers, conveyors, mining equipment, cement machinery, steel-processing equipment, material-handling systems and large process machines.

Its embedded EtherNet/IP communication makes it suitable for integration with centralized PLC, DCS, HMI and SCADA architectures.

The IP54 / NEMA Type 12 enclosure and 800 mm deep MCC-style construction provide a configuration intended for large industrial electrical installations.

The model does not include an internal dynamic-braking transistor, so braking requirements should be evaluated separately at the system-design level.

The most important mechanical consideration is that this is an MCC-style Frame 9 package rather than a small standalone drive. The cabinet depth is approximately 800 mm, while the final overall height, width and total weight are configuration-dependent.

For a large motor application around 560 kW normal duty, the 20G11JC1K0AN0NNNNN represents a high-capacity solution with substantial current capability, industrial enclosure protection, network integration and expandable control architecture.

For applications around 400–500 kW, a smaller high-power configuration may be more appropriate.

For applications above 560 kW, the 1,090 A, 1,175 A or 1,465 A configurations provide progressively greater capacity.

When selecting the final drive, the most important parameters to verify are motor rated current, motor voltage, duty classification, overload requirements, acceleration and deceleration characteristics, mechanical inertia, braking requirements, transformer capacity, cable sizing, cabinet cooling, environmental conditions, communication requirements and machine safety requirements.
