The 5 A output rating is one of the most important selection parameters for this model.

When selecting the drive for a motor, the motor nameplate current should be compared with the applicable drive current rating.

Motor power in kilowatts is useful for initial selection, but it should not be used as the only selection criterion.

The actual motor current, duty cycle, acceleration requirements and mechanical load should also be considered.

---

5. Normal-Duty Rating

For normal-duty operation, the drive is rated at approximately:

2.2 kW / 5.0 A

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

Typical normal-duty applications include:

• Fans
• Pumps
• Conveyors
• Small material-handling systems
• Feeders
• Packaging equipment
• General rotating machinery

For these applications, the drive can provide adjustable speed while maintaining controlled acceleration and deceleration.

The normal-duty overload capability also allows the drive to handle temporary increases in load within the specified limits.

---

6. Heavy-Duty Rating

The heavy-duty rating is approximately:

1.5 kW / 3.5 A

Heavy-duty operation should be considered when the machine requires greater overload capability or higher torque during demanding operating conditions.

Examples can include:

• Loaded conveyors
• Feed mechanisms
• Material-handling equipment
• High-inertia machines
• Repeated acceleration and deceleration
• Machines with higher starting torque requirements

The important point is that the normal-duty and heavy-duty ratings are not interchangeable.

A motor may have a nominal power rating that appears suitable, but if the machine has high starting torque or frequent overload conditions, the heavy-duty rating may become the more appropriate selection criterion.

---

7. Physical Dimensions and Weight

These figures should be regarded as product-package reference values for engineering and preliminary cabinet planning.

When designing a control cabinet, additional clearance should be provided for airflow, power cables, control cables, terminals and maintenance access.

---

8. Product Introduction

The 20G11RC5P0JA0NNNNN is designed to regulate the speed and operating behavior of three-phase AC motors.

A conventional motor connected directly to a fixed-frequency power supply generally operates at a relatively fixed speed.

An AC drive changes the frequency and voltage supplied to the motor.

This makes it possible to control the motor according to the actual requirements of the machine.

For example, a conveyor does not always need to run at maximum speed.

With a variable frequency drive, the conveyor speed can be increased or reduced according to the production process.

Similarly, a pump can operate at a lower speed when process demand is low and increase speed when demand rises.

A fan can also reduce speed when less airflow is required.

This flexibility is one of the main reasons industrial variable frequency drives are widely used.

---

9. Main Control Functions

9.1 V/Hz Control

V/Hz control is a relatively straightforward motor-control method.

It is suitable for applications where the load does not require advanced torque control.

Typical applications include:

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

It is often selected when the primary requirement is reliable and adjustable motor speed.

---

9.2 Sensorless Vector Control

Sensorless vector control provides better motor performance than basic V/Hz control in many applications.

It can provide improved torque control, especially at lower speeds.

This makes it useful for:

• Conveyors
• Feeders
• Material handling
• Machine tools
• Production machinery
• Variable-load applications

The actual performance depends on motor parameters, drive tuning and machine characteristics.

---

9.3 Flux Vector Control

The PowerFlex 755 platform supports advanced vector-control functions.

These functions can be useful when accurate motor torque and speed control are important.

Applications may include:

• High-performance conveyors
• Material handling
• Position-related machinery
• Industrial processing equipment
• Machines requiring better low-speed control

Feedback devices can also be used in suitable configurations when the application requires more precise control.

---

10. Embedded EtherNet/IP Communication

One of the major advantages of this model is its embedded EtherNet/IP communication capability.

The drive can communicate with a control system without requiring a separate external communication module for basic EtherNet/IP integration.

The control system can exchange information such as:

Information	Typical Purpose
Start command	Start motor
Stop command	Stop motor
Speed reference	Set motor speed
Direction command	Forward/reverse control
Actual speed	Motor monitoring
Output current	Load monitoring
Drive status	Machine sequencing
Fault status	Troubleshooting
Warning status	Preventive maintenance
Parameter information	Configuration
Diagnostic information	Maintenance

This makes the drive suitable for automated production lines.

It can become an integrated part of the machine control architecture rather than operating as an independent device.

---

11. Dynamic Braking

The model includes an internal dynamic braking transistor.

Dynamic braking is useful when a motor must decelerate quickly or when the machine has significant rotating inertia.

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

The braking system can direct this energy to an appropriately selected braking resistor.

The resistor converts the energy into heat.

This can provide better stopping performance than simply relying on a long deceleration ramp.

Dynamic braking can be particularly useful for:

• High-inertia conveyors
• Material-handling equipment
• Feeders
• Repetitive start/stop machinery
• Rotating equipment
• Machines requiring faster stopping

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

---

12. PID Process Control

The PowerFlex 755 platform supports PID control.

This is useful for applications where motor speed needs to respond automatically to process feedback.

For example, in a pressure-control application:

1. A pressure sensor measures the actual pressure.
2. The measured value is sent to the control system or drive.
3. The drive compares the actual value with the desired setpoint.
4. The drive adjusts motor speed.
5. Motor speed changes the pump output.
6. The pressure moves toward the required setpoint.

This principle can also be applied to:

• Flow control
• Pressure control
• Airflow control
• Water circulation
• Cooling systems
• Process systems

---

13. Applications

13.1 Conveyor Systems

The 20G11RC5P0JA0NNNNN is well suited to small industrial conveyor systems within its current and power rating.

A conveyor can benefit from:

• Adjustable speed
• Smooth acceleration
• Smooth deceleration
• Reduced mechanical shock
• Network control
• Motor protection
• Drive diagnostics

The acceleration and deceleration ramps can be programmed according to the mechanical characteristics of the conveyor.

This can help reduce sudden stress on belts, couplings, gearboxes and mechanical components.

---

13.2 Pumps

Pump applications are another important use for variable frequency drives.

Instead of operating the motor continuously at full speed, the drive can adjust motor speed according to process demand.

Typical applications include:

• Water circulation
• Cooling-water systems
• Industrial fluid transfer
• Pressure-control systems
• Process pumping
• Utility pumping

PID control can be particularly useful when pressure or flow must be maintained automatically.

---

13.3 Fans and Blowers

Fans frequently operate at different load requirements.

A drive can reduce the motor speed when full airflow is not required.

This can provide more flexible operation.

Typical applications include:

• Industrial ventilation
• Exhaust systems
• Cooling equipment
• Process-air systems
• Factory ventilation
• Equipment cooling

---

13.4 Packaging Machinery

Packaging machinery often requires controlled motor speed.

The drive can be used for:

• Product conveyors
• Feed rollers
• Material feeders
• Film-handling systems
• Small rotating mechanisms
• Auxiliary motors

The embedded network communication can also allow the machine controller to coordinate the motor with other machine functions.

---

13.5 Material Handling

Material-handling systems often require controlled acceleration and stopping.

Sudden acceleration can cause products to shift.

Sudden stopping can produce mechanical stress.

The drive can therefore be configured with suitable acceleration and deceleration ramps.

Dynamic braking can also be used when required.

Potential applications include:

• Roller conveyors
• Transfer systems
• Sorting equipment
• Feed systems
• Material transfer machinery
• Production-line handling equipment

---

13.6 Feeders

Feeders often require adjustable and stable motor speed.

The drive can control feeder speed according to production requirements.

Potential applications include:

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

The actual suitability depends on motor current and load characteristics.

---

13.7 Small Mixers

Small industrial mixers may require controlled acceleration and sufficient starting torque.

Vector-control functions can be useful in these applications.

However, mixer applications should be evaluated carefully because the starting load can be substantially higher than the steady-state load.

---

14. Main Product Advantages

14.1 5 A Output Capacity

The 5 A output rating makes the drive suitable for motors in the approximately 2.2 kW normal-duty range.

This provides a practical capacity for many small industrial machines.

---

14.2 400 VAC Three-Phase Design

The 400 VAC three-phase configuration makes the drive suitable for common industrial three-phase motor systems.

It is appropriate for machinery designed around 400 VAC-class electrical systems.

---

14.3 Compact Frame 1 Construction

The Frame 1 configuration provides a relatively compact physical package.

This is valuable when cabinet space is limited.

The approximate dimensions are:

400.5 × 110 × 211 mm

with an approximate weight of:

6 kg.

---

14.4 Embedded EtherNet/IP

The embedded communication capability allows the drive to integrate into an industrial automation network.

This can reduce the need for extensive hardwired control signals.

---

14.5 Dynamic Braking

The internal braking transistor provides additional flexibility for applications requiring controlled stopping.

---

14.6 Multiple Motor-Control Modes

The drive can support several control methods.

This means the same product platform can be used for simple applications and more demanding industrial machinery.

---

14.7 PID Function

PID capability makes the drive suitable for process-control applications.

It can automatically adjust motor speed based on feedback.

---

14.8 Diagnostic Capability

Drive status, warning and fault information can help maintenance personnel identify operating problems.

This can reduce troubleshooting time.

---

14.9 Programmable Acceleration and Deceleration

Acceleration and deceleration times can be adjusted according to the machine.

This helps provide smoother operation.

The IP20 enclosure is intended for installation inside a suitable electrical enclosure.

It should not be treated as a waterproof or outdoor enclosure.

If the installation environment contains water, oil mist, corrosive gases, conductive dust or significant airborne contaminants, additional environmental protection should be provided.

---

16. Cabinet Installation

The drive should normally be installed vertically.

The control cabinet should provide enough room for:

• Power cables
• Motor cables
• Control wiring
• Network cables
• Air circulation
• Heat dissipation
• Maintenance access
• Terminal access

The drive itself is approximately:

400.5 mm high

110 mm wide

211 mm deep

The cabinet should be larger than these dimensions.

Additional space is necessary around the drive.

The final cabinet size should also take into account other equipment such as circuit breakers, contactors, terminal blocks, PLC equipment, communication equipment and cooling equipment.

---

17. Heat Management

AC drives generate heat during operation.

Heat is produced by:

• Power semiconductor losses
• Switching losses
• Internal electronic components
• Cooling fan operation
• Electrical conversion losses

The forced-air cooling system removes heat from the drive.

If several drives are installed in one cabinet, the total heat generated by all drives should be calculated.

Poor cabinet ventilation can increase internal temperature.

Higher temperatures can reduce equipment life and may cause thermal protection to activate.

Therefore, cabinet airflow is an important part of drive installation.

---

18. Motor Protection

The drive provides several protection and monitoring functions.

These may include:

• Electronic motor overload protection
• Overcurrent protection
• Overvoltage monitoring
• Undervoltage monitoring
• Thermal monitoring
• Ground-fault-related protection
• Output short-circuit protection
• Stall-related protection
• Drive fault monitoring

Correct motor nameplate data should be entered during commissioning.

Important motor information includes:

• Rated voltage
• Rated current
• Rated frequency
• Rated speed
• Motor power
• Motor configuration
• Motor control mode

Correct configuration is important for obtaining reliable motor performance.

---

19. Motor Selection

The drive should be selected according to the actual motor requirements.

Motor Parameter	Importance
Motor voltage	Critical
Motor current	Very critical
Motor power	Important
Motor frequency	Required
Motor speed	Important
Motor type	Important
Starting torque	Important
Load inertia	Important
Duty cycle	Important
Acceleration time	Important
Deceleration time	Important
Braking requirement	Important
Encoder requirement	Application dependent
Cable length	Installation dependent

The motor’s rated current should always be checked carefully.

A motor with a nominal power rating of 2.2 kW may have different rated current values depending on its voltage and design.

Therefore, power rating alone is not enough to determine compatibility.

---

---

24. Conveyor Application

A production conveyor driven by a 2.2 kW motor is a typical example.

The motor can be started gradually rather than being connected directly to full line voltage.

The drive can increase frequency progressively.

The conveyor then accelerates smoothly.

When the conveyor needs to stop, the drive can reduce frequency according to the programmed deceleration ramp.

If the conveyor has substantial inertia, dynamic braking can be considered.

This approach can provide:

• Smooth starting
• Smooth stopping
• Adjustable production speed
• Reduced mechanical shock
• Better machine synchronization
• Network control
• Drive diagnostics

---

25. Pump Application

Consider an industrial pump that needs to maintain a target pressure.

A pressure sensor measures actual system pressure.

The drive uses PID control to compare the measured pressure with the target.

If pressure is too low, motor speed can increase.

If pressure is too high, motor speed can decrease.

This provides variable-speed control instead of continuously operating the motor at full speed.

The result is a more flexible pumping system.

Typical applications include:

• Water circulation
• Cooling systems
• Industrial process systems
• Pressure boosting
• Fluid transfer
• Utility systems

---

26. Fan Application

Industrial fans frequently experience changing airflow requirements.

Running continuously at full speed may not always be necessary.

The drive can reduce the motor speed when airflow demand decreases.

When demand increases, the speed can be increased.

This makes the drive useful for:

• Factory ventilation
• Exhaust systems
• Cooling fans
• Air-handling equipment
• Process ventilation
• Industrial air circulation

---

27. Packaging Machine Application

Packaging equipment often requires precise coordination between several motors.

One motor may drive a conveyor.

Another motor may control product feeding.

Another may drive rollers.

The drive can receive speed commands through the automation system.

This allows machine functions to be synchronized.

Typical advantages include:

• Adjustable motor speed
• Controlled acceleration
• Controlled deceleration
• Network-based commands
• Drive status monitoring
• Fault reporting
• Flexible machine configuration

---

28. Material Handling Application

Material-handling equipment can benefit from gradual acceleration and controlled deceleration.

For example, a loaded conveyor may require a significant amount of torque during startup.

If the motor is started abruptly, the mechanical system may experience unnecessary stress.

The drive can gradually increase motor output.

Similarly, during stopping, the drive can use a controlled deceleration ramp.

If the machine has high inertia, dynamic braking can provide additional stopping capability.

---

29. Feeder Application

A feeder often needs to operate at a stable and adjustable speed.

The drive can provide the required speed reference.

The machine controller can change the speed according to production requirements.

Potential feeder applications include:

• Product feeding
• Material feeding
• Packaging lines
• Dosing systems
• Production-line feeding
• Small processing equipment

---

30. Advantages for Machine Builders

The PowerFlex 755 platform provides a consistent drive architecture.

This can be useful for machine builders who need to create multiple machine configurations.

Potential benefits include:

• Standardized drive family
• Consistent programming approach
• Network integration
• Reusable control concepts
• Flexible motor-control methods
• Diagnostic information
• Optional feedback functions
• Expansion capability
• Easier commissioning
• Simplified maintenance

If a machine manufacturer uses several different motor sizes, related models in the same series can provide a consistent engineering platform.

---

31. Advantages for End Users

For machine operators and maintenance personnel, the drive provides several practical benefits.

Adjustable Speed

The motor can operate at different speeds according to production requirements.

Smooth Starting

Acceleration can be programmed instead of applying full motor speed immediately.

Controlled Stopping

The motor can decelerate according to the programmed ramp.

Network Monitoring

Drive operating conditions can be monitored through the automation system.

Fault Information

Drive faults and warnings can assist maintenance personnel.

Process Control

PID functions can be used for pressure, flow and similar process applications.

Dynamic Braking

The braking transistor provides additional stopping flexibility.

Motor Protection

---

32. Replacement and Selection Considerations

When replacing an existing drive, the catalog number should not be selected based solely on motor horsepower.

The following parameters should be checked.

Selection Item	What Should Be Checked
Voltage	400 VAC class
Input phase	Three-phase
Motor current	Must be within drive rating
Normal-duty power	Approximately 2.2 kW
Heavy-duty power	Approximately 1.5 kW
Frame	Frame 1
Enclosure	IP20
Communication	EtherNet/IP requirements
Braking	Confirm braking requirement
Filtering	Confirm electrical system requirements
HIM	Confirm whether a keypad is required
Feedback	Confirm encoder requirements
Control method	V/Hz, vector or other required mode
Cabinet space	Check dimensions
Cooling	Check cabinet airflow
Motor cable	Check cable requirements
Environmental conditions	Check temperature, dust, moisture and altitude
Parameters	Transfer and verify configuration

The suffix of the catalog number is important.

Two drives may have similar electrical ratings but differ in filtering, braking, interface or other configuration details.

38. Overall Product Evaluation

The 20G11RC5P0JA0NNNNN is a versatile industrial AC drive for three-phase motor applications.

Its 400 VAC input class, 5 A output current, 2.2 kW normal-duty rating and 1.5 kW heavy-duty rating place it in a useful range for small and medium industrial machinery.

Its Frame 1 construction provides a relatively compact package.

The approximate dimensions are:

400.5 × 110 × 211 mm

and the approximate weight is:

6 kg.

The embedded EtherNet/IP interface makes it particularly suitable for automated production systems.

The drive can receive commands from a controller and provide operating and diagnostic information back to the control system.

The dynamic braking transistor provides additional flexibility when the machine requires controlled stopping.

The multiple motor-control methods allow the same drive platform to be used for simple V/Hz applications as well as more demanding vector-control applications.

PID functionality expands the possible application range into process-control systems such as pumps, fans and fluid-handling equipment.

The IP20 enclosure means the drive should normally be installed inside an appropriate electrical cabinet.

Good cabinet ventilation is important because the drive uses forced-air cooling and generates heat during normal operation.

For a lower-power application, a 20G11RC3P5 configuration may be considered.

For a higher-power application, the 20G11RC8P7 or 20G11RC011 configurations may provide additional capacity.

For compact machines where a smaller drive package is preferred, the PowerFlex 525 family can be an alternative.

For simpler motor-control applications, the PowerFlex 523 family can also be considered.
