2. Basic Product Information

---

3. Brand and Product Series

The 20G11ND8P0JA0NNNNN belongs to the PowerFlex 755 product family.

The PowerFlex 755 platform is designed for industrial applications where motor control, communication, diagnostics, flexibility, and system integration are important.

Compared with a basic compact inverter, the PowerFlex 755 architecture is more suitable for machinery where the drive needs to become an active part of the automation system.

---

4. Model Number

20G11ND8P0JA0NNNNN

The catalog number identifies the drive family, voltage class, current rating, and option configuration.

The 8P0 section is particularly important because it identifies the 8.0 A output-current class.

---

5. Main Electrical Parameters

---

6. Output Current

The 20G11ND8P0JA0NNNNN has an 8.0 A output-current rating.

Output current is one of the most important parameters when selecting an AC drive for a motor.

The motor should not be selected only according to horsepower. The motor nameplate current should be compared with the applicable drive current rating, particularly when the motor will operate under heavy load or frequent acceleration.

---

7. Motor Capacity

The 8 A model is intended for approximately 5 HP-class motor applications in the applicable 480 VAC configuration.

This makes it a useful step above smaller 3 HP drives.

Typical motor applications include:

• Conveyors
• Pumps
• Fans
• Blowers
• Feeders
• Material-handling machinery
• Packaging equipment
• Processing machinery
• General industrial equipment

The actual motor nameplate current should always be considered when making the final drive selection.

---

8. Normal-Duty Applications

Normal-duty operation is generally associated with applications where the motor does not continuously experience significant overload conditions.

Typical applications include:

• Centrifugal pumps
• Centrifugal fans
• Blowers
• Light conveyors
• Air-handling equipment
• Cooling equipment
• General-purpose machinery

The 8 A output class provides additional capacity for larger motors compared with the smaller 5 A model.

---

9. Heavy-Duty Applications

The drive can also be used for more demanding motor-control applications when the motor and application remain within the applicable heavy-duty rating.

Potential applications include:

• Loaded conveyors
• Feeders
• Material-handling equipment
• Small mixers
• Machinery with repeated acceleration
• Machinery with frequent stopping
• Higher-inertia loads

For heavy-duty applications, the actual overload requirement and operating cycle should be evaluated carefully.

---

10. Physical Dimensions

The model belongs to Frame 2.

A typical reference mechanical envelope for this general Frame 2 configuration is approximately:

424 mm × 135 mm × 212 mm

or approximately:

16.7 in × 5.3 in × 8.35 in

The actual installation drawing should be used for cabinet fabrication because mounting holes, clearances, cable-entry requirements, accessories, and service space can affect the required cabinet envelope.

---

11. Product Weight

The drive is a relatively compact industrial drive for its power class.

A practical reference value for the bare drive is approximately 5 kg, although actual shipping weight can be higher.

Shipping weight may include:

• Packaging
• Protective material
• Mounting hardware
• Documentation
• Accessories
• Optional modules

For transportation planning, the packaged weight should be treated separately from the bare-drive weight.

---

12. Enclosure and Protection

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

This means the drive is generally intended for installation inside a suitable control cabinet or electrical enclosure.

The cabinet should protect the equipment from:

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

The enclosure design should also provide sufficient ventilation and heat dissipation.

---

13. Cooling System

The 20G11ND8P0JA0NNNNN uses forced-air cooling.

During operation, semiconductor switching components generate heat.

The drive’s cooling system transfers this heat away from the power electronics.

Good thermal management requires consideration of:

• Ambient temperature
• Cabinet temperature
• Internal cabinet airflow
• Fan operation
• Drive loading
• Installation spacing
• Nearby heat sources
• Dust accumulation

When several drives are installed in the same cabinet, their combined heat dissipation should be considered during cabinet design.

---

14. Embedded EtherNet/IP

A major advantage of the 20G11ND8P0JA0NNNNN is its embedded EtherNet/IP communication capability.

This allows the drive to communicate directly with a networked automation system.

Typical information exchanged includes:

This network capability makes the drive suitable for automated production systems.

---

15. Dynamic-Braking Transistor

The model incorporates a dynamic-braking transistor.

Dynamic braking is particularly useful when the motor must slow down quickly.

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

A braking circuit and appropriately selected resistor can dissipate this energy.

Typical applications include:

• Conveyors
• Feeders
• Packaging machines
• Material-handling systems
• Rotating equipment
• Machines with frequent stopping
• High-inertia loads

The actual braking resistor should be selected based on the machine’s inertia, stopping time, braking frequency, and energy requirements.

---

16. EMC Filtering

The model incorporates an EMC-filtered configuration.

Electromagnetic compatibility is important in industrial automation because high-frequency switching can generate electrical noise.

The drive’s filter configuration helps manage this noise, but the complete installation still depends on:

• Proper grounding
• Shielded motor cable
• Correct cable routing
• Separation between power and control wiring
• Proper cabinet bonding
• Appropriate motor-frame grounding
• Correct cable termination

Good installation practices are essential for reliable operation.

---

17. CM Jumper

The catalog configuration includes an installed CM jumper.

This forms part of the drive’s common-mode and EMC configuration.

The jumper configuration should be considered when the drive is installed in a particular grounding system.

The electrical installation should be designed according to the requirements of the overall power system rather than treating the drive as an isolated component.

---

18. Human Interface Module

The catalog number indicates a blank / no HIM configuration.

This means the drive does not include a local Human Interface Module as part of the specified catalog configuration.

This arrangement can be useful when the drive is primarily controlled through:

• PLC
• EtherNet/IP
• Remote HMI
• Supervisory control system
• Centralized machine-control software

A local interface can be considered when direct local operation is required.

---

19. Product Introduction

The 20G11ND8P0JA0NNNNN is designed to control the speed and operation of a three-phase AC motor.

Traditional motor starters typically provide basic switching.

An AC variable frequency drive provides a much broader range of control.

The drive changes the electrical frequency and voltage supplied to the motor so that the motor can operate at different speeds.

This allows the machine to control:

• Speed
• Acceleration
• Deceleration
• Direction
• Stopping
• Process throughput
• Motor loading
• Machine synchronization

The result is a more flexible motor-control solution for industrial equipment.

---

The internal braking transistor gives the system additional flexibility when controlled stopping is required.

---

20.6 Compact Frame 2 Design

The Frame 2 construction provides a relatively compact package for an approximately 5 HP drive.

This is helpful when electrical cabinet space is limited.

---

20.7 Forced-Air Thermal Management

The forced-air cooling system supports continuous industrial operation when the drive is installed correctly and sufficient ventilation is provided.

---

This can reduce troubleshooting time and help maintenance personnel identify abnormal operating conditions.

---

21. Typical Product Applications

---

The drive is well suited to fan and blower applications.

Motor speed can be adjusted according to required airflow.

Typical applications include:

• Factory ventilation
• Exhaust systems
• Cooling systems

35. Comparison of the Recommended Models

---

36. Why Choose the 20G11ND8P0JA0NNNNN?

The 20G11ND8P0JA0NNNNN occupies an important position between the smaller 3 HP class and larger 7.5 HP class PowerFlex 755 drives.

The smaller 20G11ND5P0JA0NNNNN has a 5 A current class.
