---

20. Application Example — Conveyor

A typical conveyor application can be arranged as:

PLC → EtherNet/IP → 20G11RD5P0AA0NNNNN → Three-Phase Motor → Conveyor

The controller can send a speed reference to the drive.

The drive then controls the motor according to the requested speed.

The controller can also monitor:

• Running status
• Speed
• Current
• Warnings
• Faults
• Drive condition

This architecture is particularly useful in automated production lines.

---

21. Application Example — Pump

For a pump application, the drive can operate according to a pressure or flow requirement.

A typical operating sequence is:

Low pressure → Increase motor speed

Target pressure → Maintain motor speed

High pressure → Reduce motor speed

This provides smoother process control compared with simply switching a fixed-speed motor on and off.

---

22. Application Example — Fan

For a fan or blower system, the motor speed can be adjusted according to actual airflow demand.

For example:

Low demand → Low speed

Medium demand → Medium speed

High demand → High speed

This makes the drive suitable for machine ventilation, industrial airflow and auxiliary cooling systems.

---

23. Application Example — Packaging Machine

A packaging machine may require several different motor speeds during one production cycle.

For example:

Loading → Low speed

Transport → Medium speed

Positioning → Controlled low speed

Stopping → Controlled deceleration

The drive can receive the speed and operating commands from the machine controller.

---

24. Application Example — Material Handling

Material-handling equipment often benefits from controlled acceleration and deceleration.

The drive can gradually increase motor speed instead of applying full speed immediately.

This can help reduce:

• Mechanical shock
• Belt stress
• Coupling stress
• Sudden movement
• Product displacement

Dynamic braking can also be useful when the machine requires controlled stopping.

---

25. Installation Considerations

Because the product uses an IP20 open-type enclosure, installation should normally be inside an appropriate electrical cabinet.

The cabinet should take the following into account:

Consideration	Requirement
Cabinet temperature	Must remain within allowable operating range
Ventilation	Adequate airflow required
Cable routing	Separate power and sensitive control wiring where appropriate
Grounding	Proper protective grounding required
Motor cable	Correctly sized for current and installation
Network cable	Proper industrial Ethernet installation
Maintenance	Sufficient access should be provided
Heat dissipation	Drive losses must be considered
Clearance	Allow sufficient space around the drive
Environment	Protect against water, dust and contamination

The drive’s physical dimensions should not be treated as the complete cabinet footprint.

Additional cabinet space is needed for wiring and maintenance.

---

26. Thermal Considerations

The drive is air cooled.

Heat generated by the power electronics must be removed from the enclosure.

When multiple drives are installed in one cabinet, the combined heat output needs to be considered.

Important factors include:

• Cabinet size
• Ambient temperature
• Airflow
• Fan operation
• Heat from nearby components
• Dust accumulation
• Drive loading
• Switching frequency

A properly designed cabinet can help prevent unnecessary thermal stress.

---

27. Maintenance Recommendations

Regular inspection can help maintain stable operation.

Maintenance Item	Inspection
Cooling fan	Check operation
Air passages	Check for blockage
Cabinet	Check for dust
Power terminals	Check connection condition
Motor cable	Inspect insulation and connections
Grounding	Verify grounding
Network cable	Check physical condition
Drive temperature	Look for abnormal heating
Fault history	Review repeated faults
Motor current	Check for abnormal increase
Braking system	Check where frequently used
Cabinet ventilation	Verify airflow

---

28. Troubleshooting Table

Problem	Possible Cause / Inspection Area
Motor does not start	Enable signal, start command, fault status
Overcurrent during acceleration	Acceleration time, motor load, mechanical resistance
Overvoltage during stopping	Deceleration time, braking requirements
Motor overheating	Load, ventilation, motor condition
Drive overheating	Cabinet airflow, ambient temperature
Incorrect motor speed	Speed reference and parameters
Network communication loss	Ethernet connection and configuration
Unexpected stop	Fault history and control logic
Process pressure unstable	PID settings and feedback
Repeated drive faults	Motor, load, wiring and environmental conditions
Excessive vibration	Motor alignment, coupling and mechanical system

---

29. Why Choose the 20G11RD5P0AA0NNNNN?

The main reason to choose this model is the combination of 3 HP-class motor capacity and advanced industrial drive functionality.

A simple compact drive may be sufficient for basic speed control.

However, a machine requiring:

• EtherNet/IP
• Centralized PLC control
• Dynamic braking
• PID control
• Detailed diagnostics
• Advanced motor control
• Flexible configuration
• Industrial automation integration

can benefit from the PowerFlex 755 architecture.

The 20G11RD5P0AA0NNNNN therefore fits particularly well in applications where the motor is relatively small but the control requirements are more sophisticated.

35. Final Product Assessment

The 20G11RD5P0AA0NNNNN is a 480 VAC, three-phase, 5 A PowerFlex 755 AC drive designed for industrial variable-speed motor applications.

Its principal rating is approximately 3 HP / 2.2 kW for normal-duty operation and 2 HP / 1.5 kW for heavy-duty operation.

The model combines a relatively compact Frame 1 mechanical package with advanced industrial functions.

Its approximate dimensions are 400 mm × 190 mm × 211.1 mm, and its approximate weight is 6 kg.

The built-in EtherNet/IP interface makes it particularly suitable for PLC-controlled automation systems.

The internal dynamic-braking transistor provides additional flexibility for machines that require controlled stopping and deceleration.

The EMC filtering, PID functionality, DC terminals, air-cooled construction and flexible PowerFlex 755 architecture further broaden its application range.

For a machine using a motor around 3 HP, this model is a strong candidate when the application requires more than basic variable-speed control.

For a smaller 2 HP-class motor, the 20G11RD3P4AA0NNNNN is a logical same-family comparison.

For the same general 5 A / 3 HP capacity with a different configuration, the 20G11RD5P0JA0NNNNN is the closest comparison.

For higher motor capacity, the 20G11RD8P7AA0NNNNN and 20G11RD011AA0NNNNN can be considered.

For applications where cabinet space, simplicity and cost are more important than the broader PowerFlex 755 feature set, the compact PowerFlex 525 and PowerFlex 523 families provide alternative solutions.

Overall, the 20G11RD5P0AA0NNNNN is best suited to industrial conveyors, pumps, fans, feeders, packaging equipment, material-handling machinery and other automated systems requiring reliable three-phase variable-speed motor control together with industrial networking, diagnostics, controlled acceleration/deceleration and process-control functionality.
