The approximate weight of 162 kg also means that mechanical lifting and suitable installation equipment should be considered during project planning.

---

4. Electrical Rating

The 20G14TC567AN0NNNNN is a high-current industrial drive.

Its Normal Duty rating is approximately 567 A, corresponding to approximately 315 kW.

Its Heavy Duty rating is approximately 472 A, corresponding to approximately 250 kW.

Its Light Duty capability is approximately 612 A / 355 kW class.

Duty Rating	Approx. Current	Approx. Motor Power
Light Duty	612 A	355 kW
Normal Duty	567 A	315 kW
Heavy Duty	472 A	250 kW

These ratings provide a useful way to understand the application range of the drive.

A variable-torque application such as a large fan or pump may be able to make use of the higher Light Duty capacity.

A more demanding machine requiring greater torque or overload capability should be evaluated against the Heavy Duty rating.

Motor nameplate current remains the most important starting point for final drive selection.

---

5. What the 567 A Rating Means in Practice

A 567 A Normal Duty rating places the drive firmly in the large-industrial-drive category.

This is not a compact machine inverter.

The drive is intended for motor systems where hundreds of amperes of output current may be required continuously or during demanding operating conditions.

Typical equipment in this range can include:

• Large water pumps.
• Industrial circulation pumps.
• Large ventilation fans.
• Mining conveyors.
• Cement conveyors.
• Process blowers.
• Large material-handling machinery.
• Heavy process equipment.
• Large rotating machinery.

The final suitability depends on the motor’s actual rated current and the application’s duty cycle.

---

6. DC Input With Precharge

The DC input with precharge configuration is one of the defining characteristics of the 20G14TC567AN0NNNNN.

Rather than receiving the main power directly as a conventional three-phase AC input to an individual drive, this configuration is intended for a DC-input power architecture.

This is particularly useful for common-DC-bus systems.

The precharge arrangement controls the initial charging of the drive’s DC-link capacitors.

This is important in high-power installations because the DC-link capacitors represent a substantial electrical load when first energized.

A properly designed precharge system helps control the initial charging process and allows the high-power DC bus to be brought into service in a controlled manner.

---

7. Common DC Bus Applications

The TC configuration is particularly useful in systems where several drives share a common DC bus.

A common DC bus can provide a coordinated power architecture for machines containing multiple motors.

For example, one motor may be accelerating while another is decelerating.

Depending on the overall system architecture, energy generated by one motor during regeneration may be available to other drive sections on the shared DC bus.

This can make the common-DC-bus approach attractive for:

• Multi-drive machines.
• Coordinated conveyor systems.
• Large production lines.
• Material-handling equipment.
• Multi-motor processing systems.
• Large automated machinery.

The common DC bus must be properly engineered with appropriate protection, precharge, disconnecting, grounding, bus capacity, fault handling, and regenerative-energy management.

---

8. AN Configuration

The AN0 configuration is an important part of the catalog number.

For the 20G14TC567AN0NNNNN, the configuration includes the specified filtering and CM jumper arrangement.

This should be considered when comparing the drive with the corresponding JN configuration.

For example:

Model	Configuration
20G14TC567AN0NNNNN	AN configuration
20G14TC567JN0NNNNN	JN configuration

The two models are closely related in current and power capacity, but catalog-number differences should be evaluated before treating them as interchangeable.

A replacement check should consider:

• Filtering.
• Common-mode jumper.
• Grounding.
• Braking.
• Input arrangement.
• Cabinet configuration.
• Communication.
• Motor duty.
• Existing system architecture.

---

9. Dynamic Braking

The 20G14TC567AN0NNNNN is specified without an internal dynamic-braking transistor and without an internal braking resistor.

This configuration is suitable for applications where the machine does not require substantial internal dynamic braking.

However, applications with high inertia can generate significant regenerative energy during deceleration.

When a large motor slows down, mechanical energy can flow back toward the drive’s DC bus.

If this energy is not consumed elsewhere, DC-bus voltage can rise.

Therefore, braking requirements should be evaluated carefully for:

• High-inertia conveyors.
• Hoisting systems.
• Centrifuges.
• Large rotating drums.
• Rapid-stop machinery.
• Large fans.
• High-speed process equipment.

If the application requires frequent rapid deceleration, an external braking or regenerative solution may be necessary.

---

10. Mechanical Specifications

Mechanical Parameter	Specification
Model / Part Number	20G14TC567AN0NNNNN
Frame	8
Construction	Open Type
Approx. Height	2145 mm
Approx. Width	778 mm
Approx. Depth	421 mm
Approx. Dimensions	2145 × 778 × 421 mm
Approx. Weight	162 kg
Cooling	Forced Air
Mounting	Industrial Cabinet
Cabinet Integration	Required
Service Clearance	Required
Mechanical Handling	Lifting Equipment Recommended

Frame 8 equipment is physically large.

The approximately 2145 mm overall height should be taken seriously when planning the cabinet, equipment room, transport route, and installation area.

The approximately 162 kg weight also means that the drive should not be treated as a component that can be installed by ordinary manual handling.

---

11. Cabinet Installation

The open-type construction allows the drive to be integrated into a larger industrial electrical system.

A suitable cabinet should provide:

• Physical protection.
• Adequate cooling.
• Safe power connections.
• Proper grounding.
• Suitable cable entry.
• Service access.
• Separation of power and control wiring.
• Appropriate environmental protection.

The cabinet should also be designed around the entire system rather than just the drive.

High-power systems may include:

• Disconnects.
• Fuses.
• Busbars.
• DC bus components.
• Reactors.
• Contactors.
• Control power supplies.
• Network equipment.
• PLC equipment.
• Auxiliary cooling equipment.
• Monitoring equipment.

All of these components occupy physical space and contribute to the cabinet’s thermal load.

---

12. Cooling and Thermal Management

The 20G14TC567AN0NNNNN uses forced-air cooling.

The cooling fans move air through the power section to remove heat generated by the switching devices.

Because the drive is designed for high-power operation, airflow is a major part of system reliability.

The cabinet should be designed to prevent:

• Hot-air recirculation.
• Restricted intake airflow.
• Blocked exhaust paths.
• Excessive dust accumulation.
• High internal cabinet temperature.
• Contamination of cooling passages.

Regular inspection of cooling fans and air passages is recommended in industrial environments.

---

13. Environmental Specifications

Environmental Parameter	Typical Specification / Consideration
Model / Part Number	20G14TC567AN0NNNNN
Operating Temperature	Approximately 0–50 °C
Storage Temperature	Approximately -40 to +70 °C
Relative Humidity	Approximately 5–95%, non-condensing
Cooling	Forced Air
Installation Environment	Industrial Enclosure
Condensation	Must Be Prevented
Dust	Appropriate Enclosure Protection Required
Corrosive Atmosphere	Additional Protection May Be Required
High Ambient Temperature	Engineering Review / Derating May Apply
High Altitude	Derating May Apply

Environmental conditions can have a direct effect on drive thermal performance.

A drive installed in a clean, temperature-controlled electrical room has very different cooling requirements from the same drive installed in a hot, dusty industrial area.

---

14. Embedded EtherNet/IP

The 20G14TC567AN0NNNNN includes embedded EtherNet/IP capability.

This allows the drive to become part of a networked industrial control system.

A PLC or supervisory controller can exchange information with the drive through the industrial network.

Typical information can include:

• Start commands.
• Stop commands.
• Speed reference.
• Drive status.
• Output frequency.
• Output current.
• Fault status.
• Warning status.
• Diagnostic information.
• Operating data.

This can simplify the control architecture of large machines.

It can also make troubleshooting easier because drive operating information can be viewed through the automation system rather than relying entirely on local inspection.

---

15. Large Pump Applications

Large pumps are one of the most suitable application areas for this drive.

Typical applications include:

• Water-treatment pumps.
• Cooling-water pumps.
• Industrial circulation pumps.
• Process pumps.
• Mining-water pumps.
• Wastewater systems.
• Large irrigation systems.

A variable-frequency drive allows the motor to operate at different speeds.

This provides flexibility when process flow requirements change.

Instead of operating a pump at full speed continuously, motor speed can be adjusted according to the required process condition.

For large pump systems, this can provide significant operational flexibility and may reduce unnecessary energy use when the process does not require full flow.

---

16. Large Fan Applications

The drive is also well suited to large fan and blower systems.

Potential applications include:

• Furnace fans.
• Large ventilation fans.
• Mining ventilation.
• Cooling towers.
• Industrial exhaust.
• Dust collection.
• Combustion-air systems.
• Process-air blowers.

Fans often operate under changing airflow requirements.

Variable-speed operation allows the motor to follow those requirements more closely.

This can reduce the need for purely mechanical airflow control and can provide smoother process operation.

---

17. Conveyor Applications

The 20G14TC567AN0NNNNN is appropriate for large conveyor systems when the motor current and duty requirements fit the drive rating.

Possible applications include:

• Mining conveyors.
• Ore conveyors.
• Cement conveyors.
• Aggregate conveyors.
• Port material handling.
• Bulk-material conveyors.
• Large manufacturing conveyors.

Controlled acceleration can reduce mechanical shock.

This can help protect:

• Belts.
• Gearboxes.
• Couplings.
• Shafts.
• Bearings.
• Mechanical structures.

For conveyors with high inertia or frequent stopping, braking and regenerative energy must be evaluated separately.

---

18. Mining Applications

Mining operations often use very large electric motors.

The PowerFlex 755 platform can be used in applications such as:

• Mining conveyors.
• Large ventilation fans.
• Dewatering pumps.

37. Braking and Regeneration Considerations

Because the 20G14TC567AN0NNNNN does not include an internal braking transistor or braking resistor, the machine’s deceleration characteristics need to be reviewed during engineering.

Applications with low-inertia loads and slow deceleration may not require a separate braking solution.

Applications with high inertia and rapid deceleration may require additional equipment.

The system designer should evaluate:

• Motor inertia.
• Load inertia.
• Deceleration time.
• Number of stopping cycles.
• Maximum speed.
• Regenerated power.
• DC bus voltage.
• Energy absorption method.

This is particularly important for large conveyor and rotating-machine applications.

38. Maintenance Recommendations

A large industrial drive should be included in the plant’s preventive-maintenance program.

Maintenance activities may include:

• Inspecting cooling fans.
• Cleaning air passages.
• Checking cabinet filters.
• Inspecting power connections.
• Inspecting DC bus connections.
• Checking grounding.
• Checking network connections.
• Reviewing fault history.
• Reviewing warning history.
• Checking for abnormal heating.
• Checking for unusual fan noise.
• Checking fan vibration.
• Inspecting for dust contamination.

The maintenance frequency should be based on the environment and machine operating conditions.

A dusty manufacturing area may require more frequent inspection than a clean, temperature-controlled electrical room.

42. Why Choose the 20G14TC567AN0NNNNN?

The main reason to choose the 20G14TC567AN0NNNNN is its combination of high current capacity, large motor-power capability, common-DC-bus architecture, PowerFlex 755 functionality, and industrial networking.

The 567 A Normal Duty rating gives the drive useful additional capacity compared with the 540 A version.

At the same time, it remains within the same general Frame 8 mechanical platform.

This makes it a practical option for large industrial installations where the motor current is too high for a smaller drive but does not require the full capacity of the larger 650 A or 750 A models.

45. Final Product Assessment

The Allen-Bradley 20G14TC567AN0NNNNN is a high-power PowerFlex 755 Frame 8 air-cooled AC drive intended for large industrial motor-control applications.

Its 567 A Normal Duty rating and approximately 315 kW Normal Duty power capability place it firmly in the high-power industrial drive category.

For Heavy Duty applications, the approximately 472 A / 250 kW rating provides substantial capacity for applications with greater torque and overload requirements.

The Light Duty capability is approximately 612 A / 355 kW class, making the drive particularly attractive for suitable variable-torque applications where the motor load profile allows the higher Light Duty rating to be used.

The DC input with precharge configuration is a major feature of the model.

It makes the drive particularly suitable for engineered common-DC-bus systems and multi-drive architectures.

The embedded EtherNet/IP capability allows the drive to integrate into a modern industrial automation network and exchange operating and diagnostic information with the control system.

The large Frame 8 construction is appropriate for this level of power.

With approximate dimensions of 2145 × 778 × 421 mm and an approximate weight of 162 kg, cabinet design, mechanical support, transportation, lifting, cable routing, and ventilation should all be considered before installation.

The drive is particularly well suited to:

• Large water pumps.
• Industrial circulation pumps.
• Cooling systems.
• Large fans.
• Process blowers.
• Mining conveyors.
• Cement conveyors.
• Material-handling equipment.
• Large process machinery.
• Common-DC-bus systems.

One important selection point is the absence of internal dynamic braking.

For high-inertia equipment or machines requiring rapid and frequent stopping, regenerative energy must be evaluated and an appropriate braking strategy should be engineered if necessary.

The 20G14TC567AN0NNNNN also sits in an important position within the TC family.

The 460 A and 540 A models provide lower current capacity, while the 650 A and 750 A models provide higher capacity.

This makes the 567 A model a useful middle option for applications that need more current than the 540 A class but do not require the additional capacity of the larger models.

When replacing or comparing this drive, the entire catalog number should be considered.

Voltage, current, duty rating, DC-input architecture, precharge arrangement, filtering, CM jumper configuration, braking, communications, frame size, cabinet dimensions, motor characteristics, and application requirements should all be evaluated together.

Overall, the Allen-Bradley 20G14TC567AN0NNNNN PowerFlex 755 is best suited to large, engineered industrial motor-control systems where high current, common-DC-bus capability, network integration, robust cabinet installation, and flexible PowerFlex 755 control architecture are required.

It is a particularly strong choice for large pumps, fans, conveyors, mining systems, material-handling equipment, process machinery, and other high-power applications where a smaller drive would not provide sufficient current capacity.
