The 5.0 A output rating is one of the key selection parameters.

For motor selection, the motor nameplate current should be compared directly with the drive’s applicable output-current rating.

Motor horsepower or kilowatt rating alone should not be used as the only selection criterion.

---

5. Normal-Duty and Heavy-Duty Ratings

The drive has two important application ratings.

Normal Duty

The normal-duty rating is approximately:

2.2 kW / 5.0 A

This rating is appropriate for applications where the motor operates under a relatively normal load profile.

Typical examples include:

• Fans
• Pumps
• Conveyors
• Feeders
• General machinery
• Packaging equipment

Heavy Duty

The heavy-duty rating is approximately:

1.5 kW

Heavy-duty operation is appropriate where the motor experiences higher torque demand or more demanding overload conditions.

Examples include:

• Heavily loaded conveyors
• Feeders
• Material handling
• Machines with higher starting torque
• Applications involving repeated acceleration

This difference is important when selecting the drive.

A 2.2 kW motor used on a light-load fan application is not necessarily equivalent to a 2.2 kW motor driving a high-inertia conveyor.

The load profile must be considered.

---

6. Physical Dimensions and Weight

Weight in pounds	Approx. 13.2 lb

The approximate physical dimensions are:

H × W × D = 400.5 × 110 × 211 mm

The approximate product weight is:

6 kg

The actual control cabinet should provide additional space around the drive.

The exact cabinet dimensions should also account for power cables, control wiring, airflow, maintenance access and heat dissipation.

---

7. Product Construction

The drive is an air-cooled industrial AC drive.

The internal power section converts the incoming AC power into controlled motor output.

The control electronics continuously regulate the output according to the selected motor-control method.

The drive can therefore control:

• Motor speed
• Motor acceleration
• Motor deceleration
• Motor direction
• Motor torque
• Current
• Process feedback

The internal braking transistor provides an additional means of handling regenerative energy during motor deceleration.

---

8. Product Introduction

The 20G11RC5P0AA0NNNNN is designed for industrial applications where a standard AC motor needs adjustable speed and controlled operation.

Instead of connecting the motor directly to the fixed-frequency power supply, the drive generates a controlled output frequency and voltage.

This allows the motor to run at different speeds.

For example, a motor connected directly to a 50 Hz supply normally operates around its normal operating speed.

With a variable frequency drive, the operating frequency can be changed.

Reducing the frequency reduces motor speed.

Increasing the frequency, within the permitted operating range of the motor and machine, increases motor speed.

This makes the drive useful in machinery where production speed must change during operation.

---

9. Main Operating Functions

The PowerFlex 755 platform provides several motor-control functions.

V/Hz Control

V/Hz control provides a straightforward relationship between output frequency and voltage.

It is suitable for relatively simple loads.

Typical examples include:

• Fans
• Pumps
• Basic conveyors
• Air handling
• Simple rotating equipment

---

Sensorless Vector Control

Sensorless vector control provides improved torque control compared with basic V/Hz control.

It is useful where the motor needs better performance at lower speeds or where the load varies significantly.

Typical applications include:

• Conveyors
• Feeders
• Material handling
• Machinery
• Production equipment

---

Advanced Vector Control

Advanced control functions can provide improved control of motor torque and speed.

This is useful when the machine needs more controlled motor behavior.

The exact performance depends on the motor, drive configuration, tuning and application.

---

10. Embedded EtherNet/IP

One of the important features of the PowerFlex 755 family is its ability to integrate into industrial Ethernet-based control systems.

The drive can exchange information with the machine controller.

Typical information can include:

Data	Application
Start command	Motor starting
Stop command	Motor stopping
Speed reference	Speed control
Direction	Forward/reverse operation
Actual speed	Monitoring
Output current	Load monitoring
Drive status	Machine sequencing
Fault status	Troubleshooting
Warning status	Preventive maintenance
Parameter data	Configuration
Diagnostic information	Service

This reduces the need for large numbers of individual hardwired control signals.

---

11. Dynamic Braking

The drive incorporates an internal dynamic braking transistor.

This is useful when a motor needs to decelerate more quickly than it would under normal ramp-down conditions.

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

The braking circuit can transfer this energy to a properly selected external braking resistor.

The resistor converts the energy into heat.

Dynamic braking can therefore provide improved stopping performance.

It is particularly useful for:

• High-inertia loads
• Conveyors
• Feeders
• Material handling
• Repetitive start/stop applications
• Rotating machinery

The braking resistor must be selected according to the actual motor inertia, braking frequency and required stopping time.

---

12. PID Process Control

The drive can be used for process-control applications through PID functionality.

For example, consider an industrial pump.

A pressure sensor can provide feedback.

The drive compares the measured pressure with the desired pressure.

It then adjusts the motor speed.

When demand increases, the motor can increase speed.

When demand decreases, the motor can reduce speed.

This can be useful for:

• Pressure control
• Flow control
• Water circulation
• Cooling systems
• Ventilation
• Process machinery

---

13. Main Applications

• Process-fluid circulation
• Pressure boosting
• Fluid transfer

PID control can also be used for feedback-based operation.

---

13.3 Fans and Blowers

The drive can reduce the motor speed when less airflow is required.

Applications include:

• Industrial ventilation
• Exhaust systems
• Cooling systems
• Air circulation
• Process ventilation

---

13.4 Packaging Machines

Packaging machinery often requires controlled motor speed.

The drive can operate:

The network interface also allows the drive to become part of the machine’s control architecture.

---

13.5 Material Handling

Material-handling machinery often requires smooth acceleration and controlled stopping.

Potential applications include:

• Roller conveyors
• Transfer equipment
• Small lifting-related mechanisms
• Sorting equipment
• Product feeders
• Transfer lines

The braking function can be especially useful when stopping inertia is significant.

---

13.6 Feeders

Industrial feeders require controlled product movement.

The drive can provide adjustable speed and controlled acceleration.

This is useful for:

• Material feeders
• Product feeders
• Packaging feeders
• Production-line feeders
• Dosing-related machinery

---

13.7 Small Mixers

Small mixers can require relatively high starting torque.

The vector-control capabilities of the drive can be useful in these applications.

However, motor current and starting torque must be checked carefully before selecting the drive.

---

14. Product Advantages

14.1 2.2 kW Normal-Duty Rating

The 2.2 kW normal-duty rating makes the drive suitable for a broad range of small industrial motors.

It can be used in applications where adjustable speed is required without moving to a much larger drive frame.

---

14.2 5.0 A Output Current

The 5.0 A output current provides a useful capacity level for industrial machinery.

This allows the drive to handle motors larger than the 3.5 A class while remaining within the same general Frame 1 physical platform.

---

14.3 Advanced Motor Control

The drive supports multiple motor-control methods.

This allows the same drive platform to be used for relatively simple applications and more demanding machinery.

---

14.4 Network Integration

EtherNet/IP capability provides convenient integration into automated systems.

The drive can become part of a larger machine-control network.

---

14.5 Dynamic Braking

The internal braking transistor makes the drive suitable for applications where controlled deceleration is important.

---

14.6 PID Capability

PID functionality is useful for process-control applications.

It allows the drive to respond to feedback from sensors.

---

14.7 Programmable Acceleration and Deceleration

Adjustable ramps allow engineers to control how quickly the motor starts and stops.

This can reduce:

• Mechanical shock
• Belt stress
• Gearbox stress
• Coupling stress
• Product movement

---

14.8 Diagnostics

The drive can provide operating and fault information.

This can make maintenance easier.

Instead of relying only on physical inspection, technicians can use drive information to identify potential electrical or operational problems.

---

15. Environmental Parameters

Parameter	Typical Specification
Enclosure	IP20
Enclosure type	NEMA/UL Open Type
Cooling	Forced air
Installation	Indoor / protected cabinet
Operating environment	Industrial
Humidity	Non-condensing environment recommended
Outdoor use	Requires suitable additional enclosure
Water exposure	Not suitable without additional protection
Dust	Requires suitable cabinet protection
Corrosive environment	Additional protection may be required
Cabinet ventilation	Required
Mounting	Vertical

The IP20 enclosure is designed for protected electrical installation.

It is not a waterproof enclosure.

For applications involving moisture, oil mist, corrosive gases or heavy dust, an appropriate cabinet or environmental protection system should be provided.

---

16. Installation Requirements

The drive should normally be mounted vertically.

Adequate clearance should be provided around the unit.

The cabinet design should consider:

• Heat generation
• Air circulation
• Cable routing
• Maintenance access
• Terminal access
• Drive spacing
• Ambient temperature

The approximate drive dimensions are:

400.5 mm high × 110 mm wide × 211 mm deep

The approximate weight is:

6 kg

The cabinet should not be designed to exactly match the drive’s outer dimensions.

Additional space is needed for wiring and maintenance.

---

17. Heat Dissipation

Variable frequency drives generate heat during operation.

The heat comes primarily from:

• Semiconductor losses
• Switching losses
• Internal control electronics
• Cooling-system losses

The forced-air cooling system helps remove this heat.

If multiple drives are installed in the same cabinet, the combined thermal load must be considered.

Poor ventilation can result in higher operating temperatures.

Therefore, cabinet design is an important part of the overall drive installation.

---

18. Motor Protection Functions

The drive can provide various motor-protection functions.

These can include:

• Electronic overload protection
• Overcurrent protection
• Overvoltage protection
• Undervoltage monitoring
• Thermal monitoring
• Stall-related protection
• Ground-fault-related protection
• Drive fault monitoring

The exact protection behavior depends on configuration and application settings.

Correct motor parameters must be entered during commissioning.

---

19. Motor Selection Considerations

The motor should be checked against the drive’s electrical rating.

Motor Parameter	Importance
Rated voltage	Must match the drive system
Rated current	Critical
Rated power	Important
Rated frequency	Required for configuration
Rated speed	Important
Motor type	Determines control setup
Starting torque	Important for conveyors and feeders
Inertia	Important for braking
Duty cycle	Important for thermal loading
Encoder	Required only for certain advanced applications
Cable length	Important for installation

The most important selection parameter is generally the motor’s rated current.

A motor with a nominal power rating below the drive capacity may still be unsuitable if its operating current or overload requirement exceeds the drive capability.

24. Conveyor Application Example

Consider a production conveyor driven by a 2.2 kW motor.

The conveyor may need to operate at different speeds during different production stages.

The drive can receive a speed reference from the machine controller.

The motor can then accelerate gradually to the desired speed.

When the production line stops, the drive can decelerate according to the programmed ramp.

If the conveyor has significant inertia, dynamic braking can be used where required.

This provides several practical advantages:

• Smooth operation
• Reduced mechanical shock
• Adjustable production speed
• Improved machine synchronization
• Network monitoring
• Easier troubleshooting

---

25. Pump Application Example

A pump may need to maintain constant pressure.

A pressure sensor provides feedback.

The drive uses PID control to adjust motor speed.

If pressure drops, the drive can increase motor speed.

If pressure rises, motor speed can be reduced.

This provides a more flexible system than running the pump continuously at fixed speed.

Such operation is useful for:

• Water circulation
• Cooling systems
• Process fluids
• Industrial pressure systems
• Utility pumping

---

26. Fan Application Example

An industrial ventilation system may not always require maximum airflow.

The drive can reduce motor speed during periods of lower demand.

Another may drive a feeder.

Another may operate a roller or auxiliary mechanism.

Using variable-speed drives allows the machine controller to coordinate these functions.

The drive can provide:

• Speed control
• Acceleration control
• Deceleration control
• Motor protection
• Fault information
• Network status

This can improve the overall flexibility of the machine.

---

28. Material-Handling Application

Material-handling equipment can benefit from controlled acceleration and braking.

Sudden starting can cause the material to shift.

Sudden stopping can also create mechanical stress.

The drive can provide a controlled acceleration ramp and controlled deceleration ramp.

For higher-inertia systems, dynamic braking can further improve stopping behavior.

Potential applications include:

• Roller conveyors
• Transfer lines
• Sorting systems
• Feed systems
• Material positioning equipment

---

29. Maintenance Advantages

The drive’s monitoring functions can provide useful information during maintenance.

For example, if a motor repeatedly trips on overcurrent, the maintenance technician can investigate:

• Mechanical overload
• Bearing problems
• Incorrect motor parameters
• Excessive acceleration
• Motor cable problems
• Motor condition

If communication is lost, the technician can investigate the network connection and control architecture.

This makes troubleshooting more systematic.

---

30. Advantages for Machine Builders

38. Conclusion

The 20G11RC5P0AA0NNNNN is positioned as a flexible industrial drive within the PowerFlex 755 series.

Its 5.0 A output capability, 2.2 kW normal-duty rating, 1.5 kW heavy-duty rating, 400 VAC three-phase input class, Frame 1 construction, IP20 enclosure, EtherNet/IP communication, dynamic braking transistor, PID functionality and multiple motor-control methods make it suitable for a wide variety of industrial applications.

The model is particularly attractive when the machine requires more than simple frequency adjustment.

For a conveyor, it can provide smooth speed changes and controlled stopping.

For a pump, it can provide variable-speed operation and feedback-based process control.

For a fan, it can regulate airflow according to demand.

For packaging equipment, it can provide network-based speed control and machine coordination.

For material handling, its acceleration, deceleration and braking functions can help provide smoother machine operation.

When selecting a replacement or alternative model, the most important factors are motor voltage, motor current, duty cycle, braking requirement, communication requirements, cabinet dimensions and environmental conditions.

For a lower-power application, the 20G11RC3P5 family is a logical step down.

For a higher-power application, the 20G11RC8P7 and 20G11RC011 models provide higher current and power capacity.

For compact machines where the full PowerFlex 755 architecture is not necessary, PowerFlex 525 or PowerFlex 523 models can also be considered.

Overall, the 20G11RC5P0AA0NNNNN represents a strong choice for industrial motor-control applications requiring adjustable speed, reliable control, automation communication and a relatively compact Frame 1 drive package.
