1. Basic Product Information

---

2. Product Introduction

The 20G11NC030JA0NNNNN is a PowerFlex 755 industrial AC drive designed for adjustable-speed control of three-phase AC motors.

It is positioned for industrial machinery that requires more than simple motor starting and stopping. Instead of operating a motor at one fixed speed, the drive can regulate motor speed according to the process requirement.

The model has a 30 A normal-duty rating and a 15 kW normal-duty power rating. For heavier operating conditions, it is rated at approximately 22 A and 11 kW in heavy-duty service.

This makes it particularly suitable for medium-power industrial machinery where controlled acceleration, controlled deceleration, variable-speed operation, motor protection, diagnostics and industrial network integration are important.

The unit uses Frame 3 construction and forced-air cooling. Its open-type construction is intended for installation within a suitable electrical cabinet or protected control enclosure.

The built-in EtherNet/IP interface is especially useful for automated production lines because the drive can exchange operating commands, speed references, status information, alarms and fault information with the control system.

---

3. Brand and Series

The most important identification point is that 20G11NC030JA0NNNNN belongs to the PowerFlex 755 series.

It should not be confused with the PowerFlex 525 family, which is aimed more toward compact general-purpose drive applications.

The PowerFlex 755 platform is designed with a more modular architecture and is better suited to applications requiring advanced control, network integration, feedback, safety options and additional drive functionality.

---

4. Detailed Technical Parameters

---

5. Electrical Rating

The most important electrical characteristic of the 20G11NC030JA0NNNNN is its dual-duty rating.

For normal-duty operation, the drive provides:

30 A / 15 kW

For heavy-duty operation, the rating is:

22 A / 11 kW

This distinction is important when selecting a drive.

A motor that appears to be within the 15 kW range may still require a different drive selection if the application involves high starting torque, frequent acceleration, severe overload or other demanding operating conditions.

The motor nameplate current should therefore be considered together with the machine’s actual load characteristics.

---

6. Normal-Duty Rating

The normal-duty specification is:

The 15 kW normal-duty rating makes this model suitable for many medium-size industrial motors.

Typical applications include conveyors, fans, pumps, blowers, material-handling systems and general process machinery.

---

7. Heavy-Duty Rating

The heavy-duty rating is:

Heavy-duty selection becomes particularly important when the machine requires substantial torque during starting or acceleration.

Examples include:

• Loaded conveyors
• Mixers
• Material-handling machinery
• High-inertia machines
• Machines with frequent acceleration and deceleration
• Machinery with significant torque fluctuations

---

8. Physical Construction

The drive is a Frame 3 PowerFlex 755 configuration.

It uses forced-air cooling to remove heat generated by the power electronics.

The open-type IP20/IP00 construction means that the drive is generally intended to be installed inside an appropriate electrical enclosure rather than exposed directly to the plant environment.

A suitable cabinet should provide protection against:

• Dust
• Water
• Condensation
• Conductive particles
• Accidental contact
• Excessive environmental contamination

The cabinet must also provide adequate ventilation and clearance.

---

9. Dimensions and Weight

The model uses the larger Frame 3 mechanical configuration compared with the smaller Frame 2 versions.

The approximate product weight is 24 kg.

Because the exact physical dimensions can vary depending on the mechanical arrangement and associated enclosure components, the installation drawing should be used for final cabinet fabrication.

For preliminary planning, the product should be treated as a Frame 3 industrial drive rather than using the smaller Frame 2 dimensions associated with lower-current versions.

Important: for a final cabinet design, the exact dimension drawing for the specific hardware revision should be used. The 24 kg figure is useful for equipment handling and preliminary mechanical planning.

---

10. Communication Capability

One of the major features of the 20G11NC030JA0NNNNN is its integrated EtherNet/IP communication capability.

This makes the drive suitable for networked automation architectures.

Instead of wiring every command individually between the controller and drive, many operating parameters can be exchanged digitally through the industrial network.

Typical information can include:

This can simplify the control architecture of automated production equipment.

---

11. Motor Control

The PowerFlex 755 platform provides multiple motor-control approaches.

The exact control mode should be selected according to the motor type, load characteristics and performance requirements.

V/Hz Control

V/Hz control is appropriate for relatively straightforward applications.

Typical examples include:

• Fans
• Blowers
• Basic pumps
• Simple conveyors

Sensorless Vector Control

Sensorless vector control provides improved torque and speed regulation compared with basic V/Hz operation.

It is useful when the load changes during operation.

Closed-Loop / Feedback-Based Control

When the application requires more precise speed or torque regulation, feedback devices can be incorporated using suitable hardware and configuration.

This can be useful for:

• Hoists
• High-performance conveyors
• Winding equipment
• Machinery requiring accurate speed regulation

---

12. Dynamic Braking

The model includes an internal dynamic-braking transistor.

This is an important feature for machines where the motor must decelerate quickly.

When a motor is decelerated, the rotating mechanical system can return energy to the drive’s DC bus.

If the application requires rapid or controlled stopping, an appropriate braking resistor arrangement can be used to dissipate this energy.

Potential applications include:

• High-inertia conveyors
• Material-handling equipment
• Mixers
• Rotating machinery
• Hoisting-related equipment
• Machines requiring short stopping times

---

13. Integrated EMC Filtering

The model includes an integrated EMC filter configuration.

This can help reduce conducted electromagnetic interference associated with drive operation.

EMC performance is affected by the complete installation, however.

Cable type, motor cable length, grounding, cabinet design, routing and installation practices all influence the final system performance.

The integrated filter should therefore be viewed as one part of the overall EMC design.

---

18. Five Same-Series / Related Models

The following five models are useful comparison choices within the same PowerFlex 755 range.

The most directly comparable model is 20G11NC022JA0NNNNN, because it is the smaller 400 V-class PowerFlex 755 configuration immediately below the 30 A model.

The 20G11NC037JA0NNNNN is a useful choice when more output current and motor capacity are required.

The 20G11NC043JA0NNNNN and 20G11NC060JA0NNNNN are more appropriate when the application requires a higher-capacity drive.

Exact dimensions and weights should be confirmed from the relevant mechanical drawing before designing a cabinet around any of these alternative models.

---

19. Same-Series Comparison

---

20. Five Popular Models from the Same Brand

For a broader product comparison, the following models represent other commonly used drive configurations within the same brand family.

These products should not be considered direct replacements merely because they belong to the same brand.

Electrical rating, control method, voltage, enclosure, communication, braking, dimensions, motor type and application requirements should all be checked before substitution.

---

21. Comparison with Compact Drives

A compact drive such as the PowerFlex 525 is generally more suitable when the application prioritizes compact physical size and straightforward variable-speed motor control.

The PowerFlex 755 is more appropriate when the system requires a higher level of integration and flexibility.

---

22. Typical Conveyor Application

Consider a conveyor driven by an 11–15 kW motor.

A conventional fixed-speed starter would normally provide only basic starting and stopping.

With the 20G11NC030JA0NNNNN, the conveyor can operate at different speeds.

For example, the control system can command a lower speed during product accumulation and a higher speed during normal production.

Acceleration can be controlled so that the conveyor does not start abruptly.

Deceleration can also be controlled to reduce mechanical shock.

The drive can report status and fault information back to the control system.

This makes the drive particularly useful in automated production environments.

---

23. Typical Pump Application

For a pump, continuously running at maximum speed may not always be necessary.

The drive can adjust motor speed according to process demand.

This can help achieve:

• Better flow control
• Better pressure control
• Smoother starting
• Reduced mechanical stress
• Potential energy savings
• Better process stability

PID functionality can also be used when the application requires automatic regulation of a process variable.

---

24. Typical Fan Application

Fan systems often operate over a range of airflow requirements.

Instead of using a fixed-speed motor and mechanical throttling method, variable-speed control can allow the motor to respond directly to the required airflow.

This can provide a more flexible control strategy.

Applications include:

• Industrial ventilation
• Cooling
• Exhaust
• Air handling
• Process ventilation

---

25. Typical Mixer Application

A mixer may require a low-speed starting condition, a higher mixing speed and a controlled stopping sequence.

The drive can be configured for these different operating requirements.

This is useful when the machine needs controlled torque and speed rather than simply full-speed operation.

For heavy material or high-viscosity processes, the actual motor current and heavy-duty requirement should be evaluated carefully.

---

26. Typical Material-Handling Application

Material-handling systems benefit from controlled movement.

For example, when a conveyor is carrying a heavy load, abrupt acceleration can produce unnecessary mechanical stress.

The drive can establish a controlled acceleration ramp.

During stopping, the internal braking transistor provides additional flexibility for applications requiring controlled deceleration.

This can be useful for:

• Heavy conveyors
• Transfer equipment
• Feeders
• Industrial handling systems
• Automated warehouse machinery

---

27. Maintenance and Troubleshooting

A variable frequency drive is both a power-conversion device and a control device.

When a machine stops unexpectedly, technicians need information about what happened.

Drive diagnostics can help identify whether the problem is associated with:

• Motor overload
• Excessive current
• DC-bus voltage
• Input power
• Temperature
• Ground fault
• Communication
• Control configuration

This can reduce unnecessary component replacement.

Maintenance personnel should still follow appropriate electrical safety procedures before inspecting or servicing the equipment.

---

28. Cabinet Design Considerations

Because this is an open-type Frame 3 drive, cabinet design is important.

The cabinet should provide adequate space for:

• Drive installation
• Input wiring
• Output wiring
• Control wiring
• Network cables
• Grounding
• Ventilation
• Maintenance

The approximate 24 kg equipment weight should also be considered when selecting the mounting panel and fixing hardware.

The final cabinet dimensions should not be based solely on the drive body dimensions.

Additional clearance is needed for wiring and airflow.
