20G11ND5P0JA0NNNNN — Detailed Product Parameters, Introduction, Applications, Advantages and Related Models

Below is a detailed English-language technical description of 20G11ND5P0JA0NNNNN. I have kept the presentation focused on the product itself and have not included website links, company names, or source references, as requested.

Important note on specifications: some mechanical data for this drive can vary depending on how dimensions are measured and whether accessories or packaging are included. For that reason, the electrical ratings below are stated as product-selection specifications, while dimensions and weight are identified as approximate values where appropriate.

---

1. Product Overview

The 20G11ND5P0JA0NNNNN is a PowerFlex 755 air-cooled AC variable frequency drive designed for three-phase industrial motor control.

It is a 480 VAC, three-phase drive with a 5 A output-current rating and a Frame 2 construction. Its rated motor capacity is 3 HP for normal-duty operation and 3 HP for heavy-duty operation in the Frame 2 configuration.

The drive incorporates embedded EtherNet/IP communication, making it suitable for networked automation systems where the motor drive needs to exchange commands, status information, speed references, alarms, and diagnostic information with a control system.

---

2. Basic Product Information

---

3. Brand and Product Series

The 20G11ND5P0JA0NNNNN belongs to the PowerFlex 755 series.

The PowerFlex 755 family is intended for applications that require more than simple motor starting and stopping. It combines variable-frequency motor control with networking, diagnostics, configurable control functions, expansion capability, and a range of application-oriented options.

For a machine builder, the major attraction is that the drive can be incorporated into a larger automation system rather than operating as an isolated motor controller.

---

4. Model Number Interpretation

The catalog number is:

20G11ND5P0JA0NNNNN

The individual portions identify the general drive configuration.

The most important portion for electrical selection is 5P0, which corresponds to the 5 A output-current class.

---

5. Main Electrical Parameters

---

6. Output Current

The drive has a 5 A output-current rating.

This is one of the most important parameters when matching the drive with a motor.

The motor should not be selected solely by horsepower. The actual motor nameplate current should be compared with the drive’s applicable current rating and duty requirements.

---

7. Motor Capacity

The model provides a 3 HP normal-duty rating and a 3 HP heavy-duty rating in its Frame 2 configuration.

This makes it suitable for applications where a motor around the 3 HP class needs adjustable speed and controlled acceleration/deceleration.

Typical motor applications include:

• Small conveyors
• Pumps
• Fans
• Blowers
• Feeders
• Packaging machinery
• Material-handling equipment
• General industrial machinery

The actual motor nameplate current remains the final selection criterion.

---

8. Normal-Duty Operation

Normal-duty applications generally involve relatively moderate overload requirements.

Examples include:

• Centrifugal fans
• Pumps
• Light conveyors
• Blowers
• Cooling systems
• Air-handling systems
• General-purpose machinery

The 3 HP normal-duty capability makes this drive a practical choice for small industrial machines where variable-speed control is required.

---

9. Heavy-Duty Operation

The model is also rated at 3 HP heavy duty in the Frame 2 configuration.

Heavy-duty operation is more relevant to machinery that requires higher torque or more demanding acceleration conditions.

Potential applications include:

• Feeders
• Material-handling machines
• Small mixers
• Conveyors with variable loading
• Machines with frequent acceleration
• Machinery requiring controlled stopping
• Higher-inertia rotating equipment

The final selection should consider the actual overload percentage, duration, acceleration time, and duty cycle.

---

10. Physical Dimensions

The Frame 2 package is relatively compact for a 3 HP industrial drive.

A commonly referenced approximate mechanical envelope is around:

424 mm × 135 mm × 212 mm

or approximately:

16.7 in × 5.3 in × 8.35 in

However, mechanical dimensions should be verified against the applicable installation drawing before cabinet fabrication because dimension conventions and accessory configurations can affect the actual installation envelope.

For actual panel construction, the published mechanical drawing should take priority over approximate dimensions.

---

11. Product Weight

A commonly listed bare-drive weight is approximately:

4.5 kg

This value should be distinguished from shipping weight.

Packaging, mounting hardware, accessories, optional modules, documentation, and other materials can increase the total shipping weight.

---

12. Enclosure

The drive uses an IP20/IP00 open-type configuration.

This configuration is normally intended for installation inside an electrical control cabinet or other suitable enclosure.

It should not be treated as a weatherproof standalone drive.

The final cabinet should protect the drive from:

• Water
• Condensation
• Conductive dust
• Metal particles
• Excessive dust
• Corrosive gases
• Mechanical impact
• Foreign objects

Proper cabinet design is especially important when the drive is installed in a manufacturing environment.

---

13. Forced-Air Cooling

The model uses forced-air cooling.

Variable frequency drives generate heat during operation because of semiconductor switching losses and other electrical losses.

The internal fan and heat-dissipation structure help remove this heat.

If several drives are installed in one cabinet, the total heat dissipation of the complete system should be considered.

---

14. Embedded EtherNet/IP

One of the major advantages of the 20G11ND5P0JA0NNNNN is its embedded EtherNet/IP capability.

This allows the drive to participate directly in an industrial Ethernet control architecture.

The controller can exchange information such as:

This is particularly useful in automated machinery where the drive needs to communicate with the machine controller.

---

15. Dynamic Braking

The model includes an internal DB transistor.

A dynamic-braking transistor is useful when the motor needs controlled deceleration.

When a motor decelerates, energy can flow back toward the drive’s DC bus.

For applications involving significant inertia or frequent stopping, a properly selected external braking resistor can be used with the braking circuit.

Typical applications include:

• Conveyors
• Feeders
• Packaging machinery
• Material-handling equipment
• Rotating machinery
• Machines with frequent stops

Dynamic braking can help shorten deceleration time and improve machine response.

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

---

16. EMC Filtering

The catalog configuration includes filtering and an installed CM jumper.

EMC filtering helps manage high-frequency electrical noise generated during variable-frequency switching.

However, good electromagnetic compatibility also depends heavily on installation.

Important factors include:

• Grounding
• Motor cable routing
• Shielding
• Cable length
• Separation of power and control wiring
• Proper termination
• Cabinet bonding
• Motor-frame grounding

The internal filter is therefore one part of the overall EMC design rather than a substitute for correct installation.

---

17. No HIM Configuration

The catalog number specifies:

Blank — No HIM

HIM refers to the Human Interface Module.

The blank configuration is useful in applications where the drive is primarily configured and controlled remotely through the automation network or control system.

This can help keep the physical drive configuration simple.

If local operator access is required, an appropriate interface option can be added depending on the system design.

---

18. Product Introduction

The 20G11ND5P0JA0NNNNN is intended to provide adjustable-speed control for industrial three-phase AC motors.

A conventional motor starter generally provides only basic start/stop control.

A variable frequency drive provides considerably more control over the motor.

The drive can vary the motor’s operating frequency and voltage so that the motor can run at different speeds according to the process requirement.

This allows the machine designer to control:

• Motor speed
• Acceleration
• Deceleration
• Direction
• Torque behavior
• Stopping
• Process throughput
• Motor operating conditions

The result is a motor-control solution that is much more flexible than fixed-speed operation.
