20G11TC540AN0NNNNN — PowerFlex 755 AC Drive

1. Product Overview

The 20G11TC540AN0NNNNN is a high-power AC variable frequency drive belonging to the PowerFlex 755 series.

It is designed for large three-phase industrial motors and is intended for applications where accurate speed regulation, controlled acceleration and deceleration, high-current motor control, industrial networking and integration with an automation system are required.

This model is part of the 400 VAC class and has a 540 A nominal output-current rating. Its published continuous ratings are approximately:

• 315 kW Light Duty
• 315 kW Normal Duty
• 250 kW Heavy Duty

The drive uses a Frame 8 construction and is intended for large industrial installations rather than compact machine applications.

The catalog configuration includes an AC input with DC terminals, embedded EtherNet/IP communication, forced-air cooling, open-type construction and no integrated dynamic-braking transistor.

A particularly important feature of this exact catalog number is the A configuration in the catalog-number option position, which corresponds to the common-mode capacitor jumper being removed. This distinguishes it from closely related configurations using the J option.

5. What Does 540 A Mean?

The 540 A value is one of the most important characteristics of this model.

It indicates that the drive is intended for a very large motor application.

At this power level, the drive is not normally used for small machine motors. It is intended for equipment such as:

• Large conveyors
• Large pumps
• Large fans
• Industrial blowers
• Compressors
• Mixers
• Rollers
• Process equipment
• Material-handling systems
• Large production machinery

The actual motor should always be selected according to its nameplate current and the required duty classification.

The kW value alone should not be used as the only selection criterion.

---

6. Light-Duty Rating

The light-duty rating is approximately:

585 A / 315 kW

Light-duty operation is generally associated with applications where the motor does not continuously require the higher overload capability associated with heavy-duty machinery.

Typical examples can include:

• Centrifugal fans
• Large centrifugal pumps
• Large blowers
• Process ventilation
• Water circulation
• Cooling systems

The exact application suitability depends on the motor current, load profile and operating conditions.

---

7. Normal-Duty Rating

The normal-duty rating is approximately:

540 A / 315 kW

This is the principal rating that makes the model attractive for large industrial motor applications.

Normal-duty operation can be suitable for machinery with relatively stable mechanical loads and moderate overload requirements.

Typical applications include:

• Large pumps
• Large fans
• Conveyors
• Process machinery
• Industrial blowers
• Material-handling equipment

---

8. Heavy-Duty Rating

The heavy-duty rating is approximately:

456 A / 250 kW

Heavy-duty operation should be considered when the application requires greater overload capability or more demanding acceleration.

Examples can include:

• High-inertia conveyors
• Heavy mixers
• Large material-handling equipment
• Machinery with frequent acceleration
• Equipment with substantial load variation
• Process machinery with high starting torque requirements

When selecting the drive for heavy-duty operation, the motor’s actual rated current should be compared directly with the heavy-duty current rating.

---

9. Input Voltage

The drive belongs to the:

400 VAC three-phase class

This voltage class is commonly associated with industrial electrical systems using approximately 380 V, 400 V or 415 V supply arrangements, depending on the specific electrical installation.

The input side is configured for:

AC Input with DC Terminals

The DC terminals can be important in applications where the DC bus is part of a larger drive-system architecture.

---

10. Output

The drive produces a variable-frequency three-phase output.

The basic energy-conversion process can be represented as:

Three-Phase AC Input

↓

Input Power Conversion

↓

DC Bus

↓

Inverter

↓

Variable-Frequency AC Output

↓

Three-Phase Motor

By changing the output frequency and voltage, the drive can control motor speed and torque.

This is fundamentally different from a fixed-frequency motor starter, where the motor generally operates close to its rated speed whenever it is running.

---

11. Embedded EtherNet/IP

The 20G11TC540AN0NNNNN includes embedded EtherNet/IP communication.

This makes the drive suitable for integration into an industrial automation network.

A typical control architecture can be:

PLC

↓

Industrial Ethernet Network

↓

20G11TC540AN0NNNNN

↓

Large AC Motor

The control system can exchange information such as:

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

This is particularly useful in factories where multiple drives must be controlled from a centralized automation system.

---

12. No Dynamic-Braking Transistor

This particular configuration does not include an integrated dynamic-braking transistor.

This is an important consideration for applications with substantial rotating inertia.

When a large motor decelerates, mechanical energy can be returned to the drive’s DC bus.

If the application requires very rapid stopping, the braking strategy must be evaluated separately.

This is especially important for:

• Large conveyors
• High-speed rollers
• Centrifuges
• Large flywheels
• High-inertia machinery
• Certain lifting systems

The absence of an integrated braking transistor does not mean the drive cannot be used for controlled deceleration. It means that the braking architecture needs to be engineered appropriately for the application.

---

13. CM Jumper Removed

The model number uses the A configuration rather than the closely related J configuration.

For this product family, this option relates to the common-mode capacitor jumper arrangement.

For the 20G11TC540AN0NNNNN, the CM jumper is configured as:

Removed

This can be significant when the drive is installed in different grounding arrangements.

The grounding and EMC configuration should therefore be reviewed before installation.

---

14. Filtered Configuration

The drive is configured with filtering.

High-power switching drives naturally produce electrical noise as a result of their switching operation.

A filtered configuration can help with electromagnetic compatibility, but good installation practices remain important.

The system should consider:

• Grounding
• Shielding
• Motor cable routing
• Control cable routing
• Network cable routing
• Cable separation
• Cabinet bonding
• Motor cable length

A correctly designed electrical installation is essential for reliable operation.

---

15. Frame 8 Construction

The 20G11TC540AN0NNNNN is a Frame 8 drive.

Frame 8 represents a high-power physical platform.

Compared with small-frame drives, Frame 8 equipment requires considerably more planning for:

• Cabinet space
• Floor loading
• Cable entry
• Cable bending radius
• Cooling
• Maintenance access
• Lifting
• Electrical clearances
• Ventilation

The drive should therefore be treated as a major industrial electrical assembly.

---

16. Dimensions

For a Frame 8 high-power drive, the final physical dimensions depend on the exact mechanical arrangement, cabinet configuration and installed options.

For planning purposes, the main drive assembly is in the large industrial Frame 8 size class.

A practical preliminary engineering allowance can be made around:

Mechanical Parameter	Approximate Planning Value
Model	20G11TC540AN0NNNNN
Frame	8
Height	Approx. 2,000–2,200 mm class
Width	Approx. 700–850 mm class
Depth	Approx. 400–600 mm class
Installation	Floor / cabinet
Cooling	Forced air
Service clearance	Additional clearance required
Cable space	Additional space required
Weight (kg)	Approx. 280–320 kg for the major open-drive assembly class

These dimensions and weight values should be treated as engineering planning estimates rather than certified shipping dimensions.

A final cabinet layout should use the mechanical drawing for the exact hardware configuration.

---

17. Weight

The 20G11TC540AN0NNNNN is a large high-power drive.

For preliminary equipment-room planning, an approximate weight in the range of:

280–320 kg

can be used for the major open-drive assembly class.

The final installed system can be considerably heavier once the following are added:

• Cabinet
• Disconnect equipment
• Busbars
• Input protection
• Cooling equipment
• Cable assemblies
• Mounting structure
• Auxiliary components

Therefore, the complete installed cabinet can exceed the drive assembly weight by a substantial amount.

Weight Category	Approximate Value
Drive model	20G11TC540AN0NNNNN
Major drive assembly	Approx. 280–320 kg
Cabinet system	Configuration dependent
Complete installed equipment	Potentially significantly above 300 kg
Weight (kg)	Approx. 280–320 kg drive assembly planning range

---

18. Product Introduction

The 20G11TC540AN0NNNNN is designed for industrial users who need variable-speed control for very large AC motors.

In a conventional fixed-speed motor system, the motor generally operates at a speed determined by the supply frequency and motor characteristics.

With a variable-frequency drive, the motor can operate at different speeds according to the process requirement.

For example, a large pump may not need full flow all the time.

A conveyor may need to operate at different production speeds.

A large fan may require reduced airflow during periods of lower demand.

A process mixer may need different speeds during different stages of production.

The drive provides the electrical control needed to adjust motor operation accordingly.

This makes the drive suitable for large automated production lines.

---

22. Energy-Control Advantages

Variable-speed control can provide energy benefits in suitable applications.

This is particularly relevant to centrifugal pumps and fans.

Instead of forcing a motor to operate continuously at full speed, the drive can reduce speed when process demand is lower.

Potential benefits include:

• Reduced unnecessary motor speed
• Improved process control
• Reduced throttling losses
• Lower mechanical stress
• Better matching between motor output and process demand

The actual energy savings depend on the load profile and process design.

---

23. Motor Selection Considerations

The drive should be matched to the motor using actual electrical data.

Important motor parameters include:

Motor Parameter	Importance
Rated voltage	Must match the drive voltage class
Rated current	One of the most important selection criteria
Rated power	Used together with current and duty
Rated frequency	Required for correct motor control
Rated speed	Important for operating range
Power factor	Used in motor-control calculations
Motor type	Must be compatible with drive control
Service factor	Important for sizing
Overload requirement	Determines duty selection
Acceleration time	Affects current demand
Deceleration time	Affects regeneration and braking
Load inertia	Important for acceleration/deceleration

A 315 kW motor is not automatically a correct match simply because the drive has a 315 kW rating.

The actual motor nameplate current should be checked.

---

24. Installation Considerations

Because the drive is a high-power Frame 8 unit, installation requires careful planning.

Important considerations include:

• Incoming power cables

The cooling system should therefore have sufficient airflow.

The installation should avoid:

• Blocked air passages
• Excessive dust
• Hot-air recirculation
• Excessive ambient temperature
• Contaminated cooling air
• Insufficient cabinet ventilation

The cooling design is particularly important when several high-power drives are installed in the same electrical room or cabinet.

---

Smooth Starting

The drive can control the acceleration profile.

This can reduce sudden mechanical stress compared with direct fixed-speed starting.

---

Centralized Control

Embedded EtherNet/IP allows the drive to become part of a larger automation architecture.

This is particularly valuable for production lines containing many motor-driven machines.

---

Diagnostic Capability

The drive can provide operating and fault information to the control system.

This can simplify maintenance and troubleshooting.

---

High-Power Capability

The 315 kW normal-duty rating places the drive firmly in the large industrial equipment category.

---

41. Recommended Electrical Selection Procedure

A practical selection process can be carried out as follows.

Step 1 — Check Motor Voltage

Confirm that the motor’s rated voltage is compatible with the 400 VAC drive class.

Step 2 — Check Motor Current

Compare the motor nameplate current against the appropriate:

• Light-duty current
• Normal-duty current
• Heavy-duty current

Step 3 — Determine Application Duty

Determine whether the machine is:

• Light duty
• Normal duty
• Heavy duty

Step 4 — Check Acceleration

Large motors may require substantial current during acceleration.

Step 5 — Check Deceleration

High-inertia machinery may require a separate braking strategy.

Step 6 — Check Communication

Confirm whether EtherNet/IP integration is required.

Step 7 — Check Cabinet Space

Frame 8 equipment requires significantly more installation space than compact drives.

Step 8 — Check Cooling

Verify that the electrical room or cabinet can remove the heat produced by the drive.

Step 9 — Check Weight

The mounting structure and lifting equipment must be capable of handling the actual delivered equipment.

Step 10 — Check Environmental Conditions

Temperature, humidity, dust and corrosive contaminants should all be considered.

44. Final Assessment

The 20G11TC540AN0NNNNN is a high-capacity industrial variable-frequency drive intended for large AC motors.

Its most important electrical characteristics are:

400 VAC

3 Phase

540 A Normal Duty

315 kW Normal Duty

585 A Light Duty

315 kW Light Duty

456 A Heavy Duty

250 kW Heavy Duty

The drive belongs to the PowerFlex 755 family and uses a Frame 8 high-power construction.

Its embedded EtherNet/IP capability makes it well suited to PLC-controlled production systems, while its high current capacity makes it suitable for large conveyors, pumps, fans, blowers, compressors, mixers and other heavy industrial machinery.

The main advantages are its high-current capability, large motor capacity, flexible variable-speed control, industrial networking, centralized monitoring and suitability for large automated systems.

The CM jumper is removed in this particular A configuration, which is an important distinction when comparing it with the closely related 20G11TC540JN0NNNNN configuration.

For comparison, the most relevant same-series models are:

1. 20G11TC460AN0NNNNN
2. 20G11TC567AN0NNNNN
3. 20G11TC650AN0NNNNN
4. 20G11TC750AN0NNNNN
5. 20G11TC770AN0NNNNN

Among these, the 20G11TC460AN0NNNNN is the lower-capacity option, while the 20G11TC567AN0NNNNN, 20G11TC650AN0NNNNN, 20G11TC750AN0NNNNN and 20G11TC770AN0NNNNN provide progressively higher current and power capacity.

For smaller machines, models such as 20G11GD014AA0NNNNN, 20G11GD022AA0NNNNN, 20G11GD027AA0NNNNN, 25B-D6P0N104 and 25B-D011N104 are more appropriate because their power and physical requirements are much lower.

For final engineering selection, the most important information is not simply the motor’s kW rating. The motor nameplate current, application duty, acceleration requirement, deceleration requirement, load inertia, voltage, environmental conditions and required braking method should all be checked before the final drive is selected.

For physical installation, the Frame 8 construction should be treated as a large industrial assembly. A preliminary planning allowance of approximately 2,000–2,200 mm height, 700–850 mm width, 400–600 mm depth and 280–320 kg drive-assembly weight can be used for early layout work, but the final cabinet and lifting design should be based on the exact mechanical configuration being installed.
