Detailed Product Parameters, Product Introduction, Applications, Advantages, Series Information and Recommended Models

Note: The following description is written as an offline technical product profile. I have not included web links, source lists, citations, or company names in the body of the content, as requested. Where exact mechanical data can vary by documentation convention, the dimensions are presented as the commonly specified overall dimensions for this configuration.

---

1. Product Overview

The 20G11GC060JA0NNNNN is a medium-to-high power industrial AC drive designed for variable-speed control of three-phase motors in industrial automation and machinery applications.

It belongs to the PowerFlex 755 product family and the broader PowerFlex 750-Series. This model is designed for applications requiring considerably more control flexibility than a basic variable-frequency drive.

The drive is configured for a 400 VAC, three-phase power system and has a 60 A normal-duty output rating. Its normal-duty power rating is 30 kW, while the heavy-duty rating is 22 kW.

The unit uses a Frame 4 mechanical configuration and forced-air cooling. It is supplied in an IP54 / NEMA Type 12 enclosure configuration, making it suitable for enclosed industrial installations where protection against dust and incidental moisture is required.

The model also incorporates embedded EtherNet/IP communication, a dynamic braking transistor, EMC filtering and a blank/no-HIM configuration.

In practical terms, the 20G11GC060JA0NNNNN is intended for industrial machines where motor speed, acceleration, deceleration, braking, communication, diagnostics and system integration all need to be managed as part of the same automation system.

---

2. Brand and Series Information

The catalog number 20G11GC060JA0NNNNN represents a specific configuration rather than simply identifying a 30 kW inverter.

The configuration includes the electrical rating, enclosure, frame, cooling method, communication capability, braking arrangement, EMC configuration and operator-interface configuration.

---

3. Detailed Technical Parameters

3.1 Main Electrical Parameters

The most important electrical rating is 60 A normal duty / 30 kW.

For heavier applications, the applicable rating is 43 A / 22 kW heavy duty.

This distinction is essential when selecting the drive for a machine with frequent overload, high starting torque or repeated acceleration and deceleration.

---

4. Normal-Duty and Heavy-Duty Ratings

The drive has two important power ratings.

The 30 kW normal-duty rating is appropriate for suitably sized applications where the load does not continuously demand the higher overload capability associated with heavy-duty operation.

The 22 kW heavy-duty rating should be considered when the application involves substantial starting torque, repeated overload, rapid acceleration, high inertia or demanding load cycles.

The motor’s nameplate current should always be compared with the applicable drive current rating.

---

5. Mechanical Parameters

The mechanical envelope is approximately 571 mm high × 300 mm wide × 220.1 mm deep.

The approximate product weight is 20 kg.

When designing a cabinet, these dimensions should not be treated as the complete installation footprint.

Additional space is required for:

• Incoming power cables.
• Motor output cables.
• Grounding connections.
• Network cables.
• Control wiring.
• Cooling airflow.
• Maintenance access.
• Terminal access.
• Cable bending radius.
• Heat dissipation.

The drive is considerably larger than the lower-power Frame 3 configurations, so cabinet layout should be considered carefully before installation.

---

6. Environmental Parameters

The IP54/NEMA Type 12 configuration provides protection appropriate for many industrial cabinets and enclosed machinery.

It is still necessary to consider the actual environment.

High humidity, aggressive chemicals, conductive dust, excessive heat or inadequate cabinet ventilation can affect long-term drive reliability.

---

7. Product Introduction

The PowerFlex 755 is an industrial AC drive platform intended for applications where motor control, communication and system flexibility are important.

The 20G11GC060JA0NNNNN represents a higher-power Frame 4 configuration within this family.

With a 60 A normal-duty rating, the drive can handle motors in the approximately 30 kW class when the application falls within normal-duty requirements.

For heavy-duty applications, the applicable rating is 43 A / 22 kW.

This makes the drive useful across a relatively broad range of industrial equipment.

The integrated EtherNet/IP interface allows the drive to be connected directly to an automation network.

A PLC or other controller can send operating commands and speed references while receiving information such as drive status, motor current, actual speed, alarms and faults.

This makes the 20G11GC060JA0NNNNN particularly useful in production systems where the drive is not an isolated component but part of a larger control architecture.

---

8. Main Features

8.1 60 A Output Rating

The 60 A normal-duty output current is the defining electrical characteristic of this configuration.

It provides significantly more capacity than the smaller 30 A, 37 A and 43 A PowerFlex 755 configurations.

This makes it appropriate for larger motors and machines requiring greater current capacity.

---

8.2 30 kW Normal-Duty Rating

The 30 kW normal-duty rating makes this drive suitable for a broad range of industrial applications.

Potential applications include:

• Large conveyors.
• Pumps.
• Industrial fans.
• Blowers.
• Mixers.
• Material-handling machinery.
• Processing machinery.
• Production equipment.
• General rotating machinery.

---

8.3 22 kW Heavy-Duty Rating

For applications with more demanding overload requirements, the drive is rated at 22 kW heavy duty.

This rating is more appropriate for applications involving:

• High starting torque.
• Frequent acceleration.
• Frequent deceleration.
• High inertia.
• Repeated overload.
• Rapid production cycles.
• Significant load fluctuations.

---

9. Embedded EtherNet/IP

The embedded EtherNet/IP interface is an important part of the product configuration.

A typical control structure can be arranged as:

PLC → EtherNet/IP Network → 20G11GC060JA0NNNNN → Motor

This architecture allows the drive to become part of a centralized automation system.

Typical control and monitoring information includes:

This capability is particularly useful in production lines containing multiple drives.

---

10. Dynamic Braking

The model includes a dynamic braking transistor.

Dynamic braking is useful when a motor and its mechanical load need to decelerate in a controlled manner.

During deceleration, the motor can return energy to the DC bus.

If this energy is not properly managed, the DC-bus voltage can rise.

A dynamic braking system can dissipate the excess energy through an appropriate braking resistor.

This makes the drive suitable for applications such as:

• High-inertia conveyors.
• Material-handling equipment.
• Certain hoisting systems.
• Centrifuges.
• Rapid-cycle machinery.
• Rotating equipment.
• Machines requiring relatively rapid controlled stopping.

The braking resistor itself must be correctly selected for the application’s resistance value, braking power and duty cycle.

---

11. EMC Filtering

The 20G11GC060JA0NNNNN is configured with EMC filtering.

This helps reduce the possibility of unwanted electromagnetic interference associated with variable-frequency drive operation.

Correct installation remains important.

Particular attention should be given to:

• Grounding.
• Shielding.
• Motor cable routing.
• Control cable routing.
• Communication cable routing.
• Separation between power and signal cables.
• Cabinet bonding.
• Motor cable length.

A filter is therefore one part of the overall EMC solution rather than a replacement for good installation practice.

---

12. No Local HIM

The model is configured as Blank / No HIM.

This means the drive does not include a standard local operator keypad as part of this catalog configuration.

This can be useful when the machine uses:

• A centralized HMI.
• PLC control.
• Remote operator stations.
• Network-based configuration.
• Supervisory control.

The no-HIM configuration can also provide a cleaner machine-panel arrangement where local keypad access is not required.

---

13. Product Applications

Therefore, cabinet thermal design becomes increasingly important with the 30 kW rating.

Important factors include:

• Ambient temperature.
• Cabinet volume.
• Internal heat sources.
• Cooling airflow.
• Fan condition.
• Ventilation arrangement.
• Mounting orientation.
• Clearance around the drive.

If several drives are installed in the same cabinet, their combined heat generation should be considered rather than evaluating each drive independently.

---

33. Motor Selection Considerations

The following parameters should be checked before pairing a motor with the drive.

The drive should be selected based on actual motor current and load characteristics rather than simply matching the motor’s kW value.

---

34. Normal-Duty Application Examples

A replacement should not be selected simply because it has the same 30 kW rating.

The voltage, current, duty rating, frame, enclosure, communication, braking and mechanical dimensions also need to be compatible.

---

38. Key Product Parameters at a Glance

---

39. Overall Product Assessment

The 20G11GC060JA0NNNNN is a robust Frame 4 industrial AC drive intended for applications requiring a higher level of motor-control capability and system integration.

Its 60 A normal-duty rating and 30 kW normal-duty capacity make it suitable for larger industrial motors than the neighboring 37 A and 43 A configurations.

At the same time, its 43 A / 22 kW heavy-duty rating allows it to be used for suitably sized applications with greater overload demands.

The integrated EtherNet/IP interface is particularly useful for modern automated production equipment.

The dynamic braking transistor adds flexibility for applications involving high inertia or controlled stopping.

The IP54 / NEMA Type 12 enclosure makes the configuration suitable for many enclosed industrial environments, while forced-air cooling provides the necessary thermal management for its higher power level.

The physical dimensions of approximately 571 × 300 × 220.1 mm and approximate weight of 20 kg should be taken into account during cabinet and machine design.

Overall, the 20G11GC060JA0NNNNN is well suited to medium-to-large conveyors, industrial pumps, fans, blowers, mixers, material-handling equipment, processing machinery and automated production systems.

Its main strength is the combination of 30 kW normal-duty power, 60 A output current, 22 kW heavy-duty capability, industrial enclosure protection, integrated networking, dynamic braking and flexible expansion options.

For applications around 30 kW under normal-duty conditions, this model provides a practical position within the PowerFlex 755 range.

For approximately 22 kW normal-duty applications, the 20G11GC043JA0NNNNN is a smaller alternative.

For approximately 37 kW normal-duty applications, the 20G11GC072JA0NNNNN provides a higher-capacity alternative.

When making the final selection, the most important factors are motor rated current, motor voltage, normal-duty or heavy-duty requirements, overload profile, acceleration/deceleration requirements, braking requirements, environmental conditions, cabinet dimensions, communication requirements and safety architecture.
