1. Basic Product Information

The 3.4 A current rating is the most important electrical parameter when matching this drive with a motor. Motor selection should be based on the actual motor nameplate voltage and current, rather than horsepower alone.

---

2. Product Introduction

The 20G11ND3P4JA0NNNNN is an industrial AC drive intended to provide adjustable-speed control for three-phase AC motors.

Compared with a simple fixed-speed motor starter, a variable frequency drive allows the motor’s operating speed to be adjusted according to the process requirement. This can improve machine control, reduce mechanical shock, and provide more flexibility in production equipment.

This particular model combines a relatively compact Frame 2 mechanical design with the functionality of the PowerFlex 755 platform.

The drive operates from a 480 VAC, three-phase supply and provides a maximum rated output current of 3.4 A.

Its 2 HP normal-duty and 2 HP heavy-duty rating makes it suitable for a wide range of small industrial motors.

The model is also equipped with embedded EtherNet/IP, allowing it to be integrated into an industrial automation network.

This is especially useful in machinery where the drive is controlled by a programmable controller and where drive operating information needs to be displayed on an HMI or monitored by a supervisory control system.

---

3. Brand and Product Series

The product belongs to the PowerFlex 755 series.

The PowerFlex 755 platform is designed for applications requiring more advanced control and integration capabilities than a basic general-purpose drive.

It is especially useful when the motor drive needs to communicate with the machine control system, provide detailed operating information, support dynamic braking, or accommodate additional control hardware.

4. Model Number

20G11ND3P4JA0NNNNN

The catalog number can be viewed as a collection of configuration identifiers.

The 3P4 section is particularly important because it identifies the 3.4 A output-current class.

This makes the model a step above the previously mentioned 2.1 A version in terms of motor capacity.

---

5. Main Electrical Parameters

---

6. Motor Capacity

The 20G11ND3P4JA0NNNNN is rated for:

• 2 HP normal duty
• 2 HP heavy duty
• 3.4 A output current

This makes it suitable for small industrial motors that require variable-speed operation.

The actual motor selection should always be checked against the motor’s nameplate.

A 2 HP motor at 480 VAC is generally within the intended application range, but the motor’s actual full-load current should be checked before final selection.

---

7. Normal-Duty and Heavy-Duty Operation

One useful feature of this model is that the Frame 2 configuration provides a 2 HP rating for both normal-duty and heavy-duty operation.

Normal-duty applications typically have relatively moderate overload requirements.

Examples include:

• Fans
• Pumps
• Light conveyors
• Blowers
• General-purpose machinery

Heavy-duty applications can involve higher starting torque or more demanding load conditions.

Examples may include:

• Material handling
• Feed mechanisms
• Small mixers
• Higher-inertia machinery
• Machinery with frequent acceleration

The exact overload profile and operating conditions should still be checked during application engineering.

---

8. Physical Dimensions

The approximate drive dimensions are:

424 mm × 135 mm × 212 mm

or approximately:

16.7 in × 5.3 in × 8.35 in

The dimensions should be treated as an installation reference rather than a substitute for the mechanical drawing.

When designing a cabinet, additional space should be provided for:

• Power cables
• Control cables
• Communication cables
• Airflow
• Maintenance
• Terminal access
• Heat dissipation

---

9. Product Weight

The approximate product weight is:

7.1 kg

The final shipping weight may differ because packaging and accessories are not necessarily included in the bare-drive weight.

---

10. Enclosure

The model uses an IP20/IP00, NEMA/UL Open Type configuration.

This means it is intended primarily for installation inside an appropriate electrical enclosure or cabinet.

It is not intended to be installed as an exposed outdoor drive without additional protection.

The cabinet should protect the drive from:

• Water
• Excessive humidity
• Conductive dust
• Metal particles
• Corrosive substances
• Mechanical impact
• Foreign objects

The final protection level depends on the complete cabinet and installation environment.

---

11. Cooling System

The drive uses forced-air cooling.

Power semiconductors generate heat during operation. The internal cooling system moves air through the drive’s heat-dissipation structure.

Correct cabinet design is therefore important.

Important factors include:

When several drives are installed in the same cabinet, the total heat generated by all drives should be considered.

---

12. Embedded EtherNet/IP

The 20G11ND3P4JA0NNNNN includes embedded EtherNet/IP communication.

This allows the drive to become part of an industrial automation network.

Typical information exchanged between the drive and controller can include:

This capability makes the drive particularly useful in automated production machinery.

---

13. Dynamic Braking

The model includes a DB transistor for dynamic braking.

Dynamic braking can be useful when a motor needs to slow down quickly or when the driven machine contains significant rotating inertia.

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

The braking circuit can direct suitable excess energy to an appropriately selected braking resistor.

This can improve:

• Deceleration performance
• Stopping control
• Machine cycle time
• Handling of high-inertia loads
• Mechanical control

Typical applications include:

• Conveyors
• Feeders
• Packaging equipment
• Rotating machinery
• Material-handling equipment
• Machinery with frequent starts and stops

The braking resistor must be selected according to the actual braking energy and duty cycle.

---

14. EMC Filtering

The model uses a filtered configuration with the CM jumper installed.

EMC filtering helps manage high-frequency electrical noise associated with variable frequency drive operation.

However, good EMC performance does not depend only on the drive’s internal filter.

The complete installation should also consider:

• Grounding
• Motor cable shielding
• Cable length
• Cable routing
• Control-cable separation
• Cabinet grounding
• Motor-frame grounding
• Proper termination

The drive’s EMC configuration therefore works together with proper installation practices.

---

15. Motor Control

The PowerFlex 755 platform provides advanced motor-control capabilities.

Depending on the selected control configuration and application requirements, the platform can be used for different types of motor control.

V/Hz Control

Suitable for relatively straightforward speed-control applications.

Typical examples:

---

Sensorless Vector Control

Provides improved torque and speed behavior compared with basic V/Hz operation.

It is useful when the load varies during operation.

Typical examples include:

• Conveyors
• Feeders
• General machinery
• Variable-load equipment

---

Flux Vector Control

Provides more sophisticated control of motor flux and torque.

This can be useful for applications where dynamic performance is more important.

---

Feedback-Based Control

Where precise speed regulation is required, suitable feedback hardware can be added to the drive architecture.

This can be useful for specialized machinery requiring improved speed accuracy.

---
