20G11TC567JN0NNNNN – Detailed Product Description, Technical Parameters, Applications, Advantages and Related Models

1. Product Overview

The 20G11TC567JN0NNNNN is a high-power industrial AC variable frequency drive belonging to the PowerFlex 755 series.

It is designed for controlling large three-phase AC motors in industrial applications where adjustable speed, controlled acceleration, controlled deceleration, process coordination and industrial network communication are required.

This model is a substantial Frame 8 drive, with a 567 A output current rating, a 315 kW normal-duty rating, a 355 kW light-duty rating, and a 250 kW heavy-duty rating.

The drive uses forced-air cooling and is intended for installation as an open-type industrial drive. It is equipped with embedded EtherNet/IP communication, making it suitable for integration into automated production lines and larger plant control systems.

A particularly important characteristic of this exact model is the J configuration, which indicates that the common-mode capacitor jumper is installed.

The model is therefore closely related to the corresponding A-version configuration, but the A and J versions should not simply be treated as interchangeable because their common-mode capacitor configurations are different.

The most important sizing value is generally the motor current rather than the motor power alone.

For a real installation, the motor nameplate current should be compared with the appropriate drive duty rating.

A 315 kW motor does not necessarily have exactly the same current requirement in every installation because motor efficiency, power factor, voltage, frequency and motor design can all affect operating current.

---

5. Duty Ratings

The drive provides different power capabilities depending on the load-duty category.

Duty	Current	Approximate Power
Light Duty	567 A class	355 kW
Normal Duty	567 A	315 kW
Heavy Duty	472 A	250 kW

The difference between these ratings is important when selecting a drive for a particular machine.

A fan or centrifugal pump may have a relatively smooth load profile and can often be considered under a lighter-duty rating.

A conveyor, mixer or high-inertia machine can place much greater demands on the drive during acceleration and operation.

For such applications, the heavy-duty rating should be considered carefully.

---

6. Product Introduction

The 20G11TC567JN0NNNNN is essentially the power-control center between an industrial electrical supply and a large AC motor.

Instead of supplying the motor directly with fixed-frequency AC power, the drive electronically controls the voltage and frequency supplied to the motor.

This provides several important functions.

The motor can start gradually instead of receiving a sudden full-voltage starting condition.

The operating speed can be adjusted according to the production process.

Acceleration and deceleration can be programmed.

The motor can communicate operating information to the plant control system.

Faults and operating conditions can be monitored.

The overall machine can therefore operate in a much more controlled manner than a simple fixed-speed motor arrangement.

---

8. 400 VAC Three-Phase Configuration

The 20G11TC567JN0NNNNN is a 400 VAC, three-phase drive configuration.

This voltage class is widely used in industrial installations based on 380–400 V three-phase power systems.

The drive is therefore particularly relevant to industrial facilities using 400 V-class electrical distribution.

The exact incoming voltage, transformer arrangement, grounding system, protection equipment and motor voltage should be verified during project engineering.

---

9. 567 Amp Current Rating

The 567 A rating is one of the most important characteristics of this model.

A current rating of this magnitude places the drive in the high-power industrial category.

It is intended for motors that require hundreds of amperes rather than the relatively small current levels associated with compact machine drives.

Applications can include:

• Large pumps
• Large fans
• Heavy conveyors
• Large blowers
• Process machinery
• Material-handling equipment
• Industrial mixers
• Large rotating equipment

The motor’s actual nameplate current should always be checked before final drive selection.

---

10. 315 kW Normal-Duty Rating

The normal-duty rating is approximately:

315 kW

This makes the model appropriate for large industrial motors in the 315 kW class when the application’s duty requirements match the normal-duty rating.

Typical examples include large pumps, fans, conveyors and process machinery.

The 315 kW rating should not be interpreted as a universal maximum motor size.

Motor current, overload requirements, acceleration requirements and environmental conditions must also be considered.

---

11. 355 kW Light-Duty Rating

The light-duty rating is approximately:

355 kW

This provides additional motor power capacity for applications where the load profile does not require the same overload capability as a heavy-duty application.

Typical examples can include:

• Centrifugal pumps
• Centrifugal fans
• Ventilation systems
• Large blowers
• Cooling systems
• Water circulation systems

The actual application should determine which duty rating is appropriate.

---

12. 250 kW Heavy-Duty Rating

The heavy-duty rating is approximately:

250 kW / 472 A

Heavy-duty applications may have:

• High starting torque
• High mechanical inertia
• Frequent acceleration
• Frequent deceleration
• High continuous load
• Significant mechanical resistance

Examples include:

• Heavy conveyors
• Mixers
• Material-handling machines
• Processing equipment
• High-inertia rotating machinery

The heavy-duty rating should be used when the application requires the additional overload capability associated with this duty category.

---

13. Common-Mode Capacitor Jumper Installed

The J configuration is significant.

For this model, the common-mode capacitor jumper is installed.

Model Configuration	CM Capacitor Jumper
20G11TC567JN0NNNNN	Installed
20G11TC567AN0NNNNN	Removed

The common-mode capacitor configuration can affect the electrical behavior of the drive with respect to grounding and common-mode currents.

Therefore, the A and J configurations should be selected according to the electrical system and installation requirements.

---

14. Embedded EtherNet/IP

The drive includes embedded EtherNet/IP communication.

This is particularly useful in automated industrial environments.

A controller can exchange information with the drive, including:

• Start command
• Stop command
• Speed reference
• Direction
• Enable
• Reset
• Drive status
• Output frequency
• Motor current
• Fault status
• Warning status
• Diagnostic information

This allows the drive to become an integrated part of a plant-wide automation system.

---

15. No Dynamic Braking

The model is specified with:

Dynamic Braking: None

This is an important consideration for machines with large rotating inertia.

When a motor decelerates, mechanical energy can return toward the drive’s DC bus.

If the machine requires rapid deceleration or frequent braking, the overall braking strategy must be evaluated.

Applications requiring high braking performance may require an appropriate external braking arrangement or another system-level solution.

This is especially important for:

• Large conveyors
• High-inertia rollers
• Large fans with significant rotating mass
• Centrifuges
• Heavy rotating equipment

---

16. Cooling System

The 20G11TC567JN0NNNNN uses forced-air cooling.

At a power rating of several hundred kilowatts, the amount of heat generated by power electronics can be significant.

Consequently, ventilation and thermal management are essential.

The installation should provide suitable airflow around the drive.

Particular attention should be paid to:

• Ambient temperature
• Airflow direction
• Cabinet ventilation
• Cooling-fan condition
• Dust accumulation
• Hot-air recirculation
• Cabinet heat dissipation

The drive should not be installed where the cooling airflow is blocked.

---

17. Physical Dimensions

Because this is a large Frame 8 drive, the equipment requires considerably more installation space than compact drives.

For planning purposes, the drive assembly is approximately in the following size range:

Mechanical Parameter	Approximate Value
Model	20G11TC567JN0NNNNN
Frame	Frame 8
Approx. height	2,145 mm
Approx. width	778 mm
Approx. depth	425 mm
Installation type	Open type
Cooling	Forced air
Approx. weight (kg)	286 kg

These figures should be regarded as approximate planning values for the drive assembly.

A complete electrical cabinet, disconnect system, bus system, cooling arrangement, incoming protection and other accessories can result in substantially greater overall dimensions and weight.

For a final mechanical drawing, the exact configuration should be checked against the equipment drawing applicable to the particular installation.

---

18. Weight

The approximate drive assembly weight is:

286 kg

This is a significant mechanical load.

Installation planning should therefore consider:

• Transportation
• Lifting
• Floor loading
• Cabinet structure
• Mounting hardware
• Maintenance access
• Replacement procedures

A lifting method should be planned before the equipment reaches the installation location.

The shipping package may weigh more than the bare drive assembly because of packaging and additional components.

---

19. Product Applications

The drive is well suited to large industrial pumping systems.

Potential applications include:

• Water transfer
• Process-water circulation
• Cooling-water systems
• Industrial pumping
• Wastewater systems
• Large circulation pumps
• Utility pumps

Variable-speed control allows pump output to be adjusted according to process demand.

This can reduce unnecessary operation at maximum speed.

---

19.2 Large Fan Systems

Large fans can consume substantial electrical power when operated continuously at high speed.

The drive can provide:

• Adjustable airflow
• Controlled acceleration
• Controlled speed
• Centralized monitoring
• Process-based speed control

Typical applications include:

• Industrial ventilation
• Exhaust systems
• Furnace systems
• Cooling systems
• Process-air systems

---

19.3 Large Conveyor Systems

Large conveyors often require powerful motors and controlled acceleration.

The drive can help reduce mechanical shock during startup.

Potential applications include:

• Bulk material conveyors
• Mining conveyors
• Production-line conveyors
• Material-transfer systems
• Heavy-duty handling systems

---

19.4 Blower Systems

Large industrial blowers may require several hundred kilowatts.

The drive can regulate blower speed according to pressure or airflow requirements.

This is useful in process plants where air demand changes throughout the production cycle.

---

19.5 Compressors

Large compressors can require substantial motor power.

Where variable-speed operation is appropriate, the drive can provide controlled acceleration and adjustable operating speed.

The final selection should consider compressor torque characteristics and the manufacturer’s motor requirements.

---

19.6 Mixers

Large mixers may experience substantial resistance during startup.

Controlled acceleration can help reduce sudden mechanical stress.

Applications include:

• Chemical processing
• Material mixing
• Industrial production
• Large process mixers
• Heavy-duty mixing equipment

---

19.7 Material-Handling Machinery

The drive can be used for large material-handling systems where motor speed must be coordinated with the overall process.

Examples include:

---

21. Energy-Saving Potential

One major advantage of variable-frequency drives is the ability to operate a motor at the speed actually required by the process.

This is particularly useful for centrifugal pumps and fans.

For example, if a pump does not need to operate at maximum output, reducing its speed can significantly change its operating power requirement.

Possible benefits include:

• Reduced unnecessary energy consumption
• Better process control
• Reduced throttling losses
• Lower mechanical stress
• Reduced wear
• Improved operating flexibility

Actual energy savings depend heavily on the machine’s load characteristics.

---

22. Motor Compatibility

The motor should be selected and checked using its complete nameplate information.

Motor Parameter	Importance
Rated voltage	Must correspond to the drive output range
Rated current	Critical for drive sizing
Rated power	Used together with current and duty
Rated frequency	Required for configuration
Rated speed	Determines operating characteristics
Power factor	Affects current requirements
Efficiency	Affects operating current
Service factor	Important for overload evaluation
Motor type	Determines appropriate control method
Load inertia	Important for acceleration
Starting torque	Important for heavy-duty applications
Speed range	Determines application suitability

The motor should therefore not be selected only by matching its kW value.

---

23. Installation Requirements

A Frame 8 drive requires considerably more installation planning than a small VFD.

Important considerations include:

• Incoming power cables
• Motor output cables
• Grounding
• Control wiring
• Network wiring
• Cable bending radius
• Cabinet ventilation
• Cooling airflow
• Maintenance clearance
• Lifting access
• Floor loading
• Electrical protection
• Environmental conditions

The installation should provide sufficient space for maintenance personnel to safely inspect and service the equipment.

The main difference is the common-mode capacitor jumper configuration.

For that reason, replacement should be based on the complete catalog configuration rather than simply matching the current rating.

---

36. Advantages of the J Configuration

The J configuration provides a defined common-mode capacitor arrangement with the jumper installed.

This can be relevant to the electrical characteristics of the drive installation.

When selecting the correct configuration, the following should be considered:

• Grounding arrangement
• Electrical distribution system
• Motor cable configuration
• EMC requirements
• Leakage-current considerations
• Installation environment
• Motor insulation characteristics

The correct configuration should be selected according to the actual electrical system rather than simply choosing the J version because it has the same current rating as another model.

---

41. Overall Product Assessment

The 20G11TC567JN0NNNNN is a high-power PowerFlex 755 AC variable-frequency drive intended for demanding industrial motor-control applications.

Its 567 A current rating, 315 kW normal-duty capability, 355 kW light-duty capability, and 250 kW heavy-duty capability make it suitable for large motors and substantial mechanical systems.

The model uses a 400 VAC three-phase configuration, Frame 8 construction, forced-air cooling, a filtered input arrangement, AC input with DC terminals, and embedded EtherNet/IP communication.

The J configuration is particularly important because the common-mode capacitor jumper is installed. This differentiates the model from the corresponding A configuration.

The drive is particularly suitable for applications such as:

• Large pumps
• Large fans
• Industrial blowers
• Large conveyors
• Material-handling equipment
• Process machinery
• Large mixers
• Compressors
• Rollers
• Water-treatment equipment
• Industrial ventilation
• Large circulation systems

From a mechanical perspective, this is a substantial piece of equipment. A planning value of approximately 2,145 mm × 778 mm × 425 mm and approximately 286 kg can be used for preliminary space and handling calculations, although the exact dimensions and total installed weight should be confirmed for the final configuration.

The closest same-series alternatives include the lower-capacity 20G11TC460JN0NNNNN and 20G11TC540JN0NNNNN, the configuration variant 20G11TC567AN0NNNNN, and the higher-capacity 20G11TC650JN0NNNNN and 20G11TC750JN0NNNNN.

For final engineering selection, the most important factors are the motor’s rated current, rated voltage, duty cycle, overload requirement, load torque, acceleration time, deceleration time, mechanical inertia, braking requirements, ambient conditions and electrical grounding arrangement.

In practical terms, the 20G11TC567JN0NNNNN can be described as a large-frame, high-current, 315 kW-class industrial AC drive designed for variable-speed control of large three-phase motors, with integrated industrial network capability and a forced-air cooling architecture.
