---

4. Electrical Rating

The most important electrical rating of the 20G11RC015JA0NNNNN is its 15.4 A normal-duty output current.

This corresponds to a normal-duty power rating of approximately 7.5 kW.

For applications requiring heavier-duty motor operation, the drive is rated at approximately 11.5 A and 5.5 kW.

Duty	Output Current	Power	Approx. Horsepower
Normal Duty	15.4 A	7.5 kW	10 HP
Heavy Duty	11.5 A	5.5 kW	7.5 HP

The difference between normal-duty and heavy-duty ratings is important when selecting the drive.

A pump or fan may normally operate under a relatively predictable load, while a conveyor, mixer, or material-handling machine may experience considerably higher torque requirements during starting or overload conditions.

For this reason, the motor’s nameplate current and the actual mechanical load should be considered before selecting the drive.

---

5. Input and Output Configuration

The drive is designed for a three-phase 400 V AC class input.

It uses an AC input configuration with precharge and DC terminals.

The output is a controlled three-phase AC supply for the motor.

The drive internally manages the electrical conversion necessary to produce a variable-frequency output.

This allows the motor to operate at different speeds rather than being limited to a single fixed operating speed.

The output frequency can be adjusted according to the programmed operating parameters and control commands.

This makes the drive suitable for machinery where motor speed needs to change according to production requirements.

---

6. Product Construction

The 20G11RC015JA0NNNNN uses a Frame 1 construction.

Its approximate dimensions are:

400 mm high × 190 mm wide × 211.1 mm deep

Its approximate weight is:

6 kg

Mechanical Parameter	Value
Model	20G11RC015JA0NNNNN
Frame	Frame 1
Height	400 mm
Width	190 mm
Depth	211.1 mm
Weight kg	Approx. 6 kg
Enclosure	IP20 / Open Type
Cooling	Forced Air
Installation	Panel Mount

The relatively compact Frame 1 construction makes the drive practical for many industrial control cabinets.

However, the cabinet designer should allow additional space around the unit for ventilation, wiring, maintenance, and heat dissipation.

---

7. Product Introduction

A variable frequency drive controls the electrical power supplied to an AC motor.

With a conventional fixed-speed motor starter, the motor normally receives the available line frequency and accelerates according to its electrical and mechanical characteristics.

A variable frequency drive provides much more control.

The 20G11RC015JA0NNNNN can control motor speed by changing the frequency and voltage supplied to the motor.

This allows the machine to operate at different speeds depending on production requirements.

For example, a conveyor can operate at low speed during loading and increase to normal production speed after the material is positioned.

A pump can operate at reduced speed when less flow is required.

A fan can reduce its speed when less ventilation is needed.

A mixer can use different operating speeds during different stages of a process.

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

---

8. How the Product Works

The basic operating principle can be divided into three stages.

Stage 1 — Receiving Electrical Power

The drive receives three-phase AC power from the electrical distribution system.

For this model, the supply belongs to the 400 V AC class.

The incoming power passes through the drive’s input and precharge system.

Stage 2 — Electrical Conversion

The drive processes the incoming electrical power through its internal power electronics.

The control system determines the required output frequency and voltage based on the motor parameters and operating commands.

Stage 3 — Motor Control

The drive provides controlled three-phase power to the motor.

The motor can then accelerate, decelerate, and operate at different speeds according to the programmed control requirements.

This provides much more flexibility than simply connecting and disconnecting the motor from the power supply.

---

9. Embedded EtherNet/IP

One of the important characteristics of this configuration is its embedded EtherNet/IP communication capability.

This allows the drive to become part of a networked industrial automation system.

The drive can exchange operating information with a controller or other compatible automation equipment.

Typical information can include:

• Start commands.
• Stop commands.
• Speed references.
• Drive status.
• Motor speed.
• Current information.
• Fault information.
• Alarm information.
• Diagnostic information.
• Selected drive parameters.

This can reduce the amount of hardwired control wiring required in some automation systems.

It also makes it easier for operators and maintenance personnel to monitor drive operation through the control system.

---

10. Dynamic Braking

The drive includes a dynamic braking transistor.

Dynamic braking is useful when a motor or mechanical load needs to decelerate quickly.

When a rotating motor slows down, energy stored in the rotating mechanical system can return toward the drive.

The braking system provides a way to manage this regenerated energy.

This is particularly useful for:

• High-inertia machinery.
• Conveyors.
• Material-handling systems.
• Machines with frequent stopping.
• Machines requiring shorter deceleration times.
• Rotating processing equipment.

The braking transistor is part of the drive configuration, but a suitable external braking resistor may still be required depending on the application.

The resistor must be selected according to the required resistance, braking energy, duty cycle, and drive requirements.

---

11. EMC Filtering

The model includes an EMC-filtered configuration.

EMC filtering is useful in industrial environments because variable frequency drives use high-speed electronic switching.

This switching can produce electrical noise.

The EMC filtering arrangement helps control conducted electrical interference.

This can be particularly useful when the control cabinet contains:

• PLC equipment.
• Ethernet devices.
• Analog instruments.
• Sensors.
• Communication modules.
• Human-machine interfaces.
• Other variable frequency drives.
• Sensitive electronic control equipment.

Correct grounding and cable routing are still important.

The filter should be considered as one part of the overall EMC installation strategy rather than as a replacement for proper wiring practices.

---

12. PID Control

The drive supports PID control.

PID control is useful when the motor speed needs to respond automatically to a process variable.

For example, a pump may need to maintain a certain pressure.

A pressure sensor can provide feedback to the control system.

If the pressure decreases, the drive can increase motor speed.

If the pressure becomes higher than the required value, the drive can reduce motor speed.

The same general principle can be used for:

• Flow.
• Pressure.
• Air volume.
• Liquid level.
• Process ventilation.
• Other feedback-controlled applications.

This can make the drive particularly useful for pump and fan systems.

---

• Production-line handling systems.

Controlled acceleration and deceleration can reduce mechanical stress on belts, couplings, gearboxes, and other transmission components.

---

19. Mixer and Processing Machinery

Mixers often require different motor speeds during different stages of operation.

For example, a machine may run slowly during material loading and increase speed during the main mixing stage.

The drive allows these operating speeds to be programmed and controlled.

Potential applications include:

• Industrial mixers.
• Blending equipment.
• Processing machinery.
• Production equipment.

The drive can operate the motor at different speeds according to process requirements.

This is useful for applications where the motor does not need to operate continuously at maximum speed.

---

21.2 7.5 kW Normal-Duty Rating

The drive provides a 7.5 kW normal-duty rating.

This makes it suitable for a substantial range of medium-sized industrial motor applications.

The 15.4 A current rating also provides a more useful selection reference than horsepower alone.

---

21.3 5.5 kW Heavy-Duty Rating

The heavy-duty rating is approximately 5.5 kW.

This provides a practical option for applications where the load requires greater overload capability than a typical variable-torque application.

---

21.4 Dynamic Braking Capability

The built-in braking transistor is valuable for applications requiring controlled deceleration.

It provides a practical foundation for dynamic braking without requiring a separate external drive braking interface.

---

21.5 Industrial Ethernet Communication

Additional space is required for:

• Input power cables.
• Motor cables.
• Control wiring.
• Network cables.
• Grounding connections.
• Airflow.
• Terminal access.

---

31. Advantages in Pump Applications

For pump applications, the main advantage is the ability to adjust motor speed according to actual flow or pressure requirements.

A fixed-speed pump may operate at full speed even when the process requires less flow.

With a variable frequency drive, motor speed can be reduced when demand is lower.

This provides more flexible operation and can make the system easier to control.

The integrated PID functionality is particularly useful when pressure or flow must be maintained automatically.

---

32. Advantages in Fan Applications

Fans often operate under changing airflow requirements.

The drive allows fan speed to be adjusted according to process demand.

This is useful in:

• Factory ventilation.
• Cooling systems.
• Exhaust systems.
• Air-handling equipment.
• Process ventilation.

The drive can also provide controlled acceleration and deceleration, which can reduce sudden mechanical stress.

---

33. Advantages in Conveyor Applications

For conveyor systems, the drive provides controlled motor operation.

The acceleration time can be adjusted to suit the mechanical system.

The deceleration time can also be programmed according to the load.

This can reduce sudden belt movement and improve the overall operating behavior of the machine.

Dynamic braking can be especially useful when the conveyor needs relatively rapid stopping.

---

34. Advantages in Automated Machinery

The embedded Ethernet capability allows the drive to become part of a larger automation system.

A controller can send operating commands to the drive.

The drive can return status and diagnostic information.

This allows the machine control system to coordinate motor operation with:

• Sensors.
• Valves.
• Other motors.
• Production equipment.
• Safety systems.
• Human-machine interfaces.

This type of integration is particularly useful in automated production lines.

---

35. Maintenance Considerations

Regular maintenance helps maintain stable drive operation.

Important inspection items include:

• Cooling airflow.
• Fan condition.
• Dust accumulation.
• Electrical connections.
• Grounding connections.
• Motor cables.
• Input power cables.
• Control wiring.
• Communication cables.

• Ventilation.

Dust buildup can restrict airflow.

Poor ventilation can increase operating temperature.

Loose electrical connections can produce abnormal heating.

For these reasons, preventive inspection should be included in the machine maintenance schedule.

---

36. Replacement Considerations

When replacing an existing drive, the complete catalog number should be checked.

The replacement drive should be compared in terms of:

Selection Parameter	Requirement
Input Voltage	400 V AC class
Input Phase	Three-phase
Motor Current	Must be within drive rating
Normal Duty	7.5 kW class
Heavy Duty	5.5 kW class
Frame	Frame 1
Cooling	Forced Air

EMC Configuration	Filtered
Braking	DB transistor
Communication	Embedded EtherNet/IP
HIM	No HIM in this configuration
Dimensions	Approx. 400 × 190 × 211.1 mm
Weight	Approx. 6 kg

A replacement should not be selected only because its horsepower appears similar.

Electrical current, duty rating, voltage, braking, communication, enclosure, dimensions, and options should all be considered.
