4. Product Introduction

The 20G11NB022JA0NNNNN is designed to regulate the speed and operating characteristics of three-phase AC motors.

Instead of connecting the motor directly to a fixed-frequency power supply, the drive converts and controls the electrical power supplied to the motor.

The output voltage and frequency can be adjusted according to the required motor speed and load condition.

A simplified system can be represented as:

Three-Phase AC Power → PowerFlex 755 → AC Motor → Mechanical Load

The mechanical load may be a:

• Pump
• Fan
• Conveyor
• Blower
• Mixer
• Machine tool
• Material-handling machine
• Process machine
• Production machine

The drive can also communicate with a PLC or other industrial controller.

A typical automation arrangement is:

PLC → EtherNet/IP → PowerFlex 755 → Motor

This allows motor operation to become part of the overall machine-control system.

---

5. Electrical Rating

The main electrical rating of the 20G11NB022JA0NNNNN is 22 A normal-duty output current.

For heavy-duty operation, the continuous current rating is approximately 15.3 A.

Electrical Parameter	Normal Duty	Heavy Duty
Model	20G11NB022JA0NNNNN	20G11NB022JA0NNNNN
Voltage	208–240 VAC	208–240 VAC
Phase	3 Phase	3 Phase
Continuous Current	22 A	15.3 A
Power	7.5 HP / 5.5 kW	5 HP / 4 kW
Cooling	Forced Air	Forced Air
Application	General / variable-torque	More demanding load

The difference between normal-duty and heavy-duty ratings is important when selecting a motor.

A motor that is suitable under a normal-duty rating may not necessarily be suitable for a constant-torque application requiring greater overload capability.

---

Suitable Applications	Conveyors, fans, machinery and other rotating loads

The presence of the braking transistor does not mean that an external braking resistor is automatically included.

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

---

10. Filtering and CM Jumper

The drive is configured with filtering and a CM jumper.

These characteristics are important when considering the electrical environment in which the drive will operate.

Filtering can help manage electrical noise and electromagnetic effects associated with variable-frequency-drive operation.

The CM configuration is related to common-mode behavior and grounding.

The complete installation should consider:

• Motor cable length

The forced-air cooling system provides active thermal management.

This is useful when the drive is operating continuously or under substantial load.

Proper ventilation remains essential.

---

23. Energy-Saving Potential

One of the main reasons to use a variable-frequency drive is the ability to match motor speed to actual process requirements.

This is especially useful for variable-torque loads.

For example, a fan may not need to operate at maximum speed throughout an entire production cycle.

Similarly, a pump may only require full flow during certain operating periods.

By reducing motor speed when demand decreases, the system may consume less energy.

Potential benefits include:

• Reduced motor speed
• Reduced mechanical output
• Improved process matching

40. Overall Product Assessment

The 20G11NB022JA0NNNNN is a versatile industrial variable-frequency drive for motors in the approximately 5 HP to 7.5 HP range, depending on the selected duty.

Its 240 VAC three-phase input, 22 A normal-duty rating, 15.3 A heavy-duty rating, compact Frame 2 construction and integrated communication capabilities make it suitable for a broad range of industrial machinery.

One of its strongest characteristics is the combination of motor-control flexibility and relatively compact physical dimensions.

With dimensions of approximately 424.2 × 134.5 × 212 mm and a weight of approximately 8 kg, it can be incorporated into many control cabinets without the mechanical requirements associated with larger PowerFlex frames.

The integrated dynamic-braking transistor is another useful feature.

For applications where the load has substantial inertia, an appropriately selected braking resistor can be used to improve controlled deceleration.

The embedded EtherNet/IP capability is valuable in automated production environments.

The drive can communicate operating commands and status information with a control system, making it possible to integrate motor speed control into a larger machine-control strategy.

The product is suitable for pumps, fans, conveyors, mixers, material-handling equipment and many other general industrial motor applications.

For variable-torque loads, variable-speed operation can also provide an opportunity to reduce energy consumption when the machine does not need to operate at full speed.

For constant-torque or high-inertia loads, the heavy-duty rating and braking requirements should receive particular attention.

The open IP20/IP00 enclosure means that the drive should normally be installed inside an appropriately protected electrical panel or cabinet.

Environmental conditions such as temperature, dust, humidity and ventilation should be controlled.

When selecting a replacement, the complete catalog number should always be checked.

Models with similar voltage, current or horsepower ratings can still have different braking, filtering, enclosure, communication or mechanical configurations.

42. Conclusion

The 20G11NB022JA0NNNNN is a compact but capable PowerFlex 755 industrial AC drive designed for three-phase motors in the approximately 5 HP heavy-duty and 7.5 HP normal-duty range.

Its 22 A normal-duty current rating, 15.3 A heavy-duty current rating, 240 VAC input, forced-air cooling, Frame 2 mechanical design, dynamic-braking transistor, filtering and embedded EtherNet/IP communication give it a broad range of practical industrial applications.

For pumps and fans, it provides adjustable speed and improved process control.

For conveyors and material-handling equipment, it provides controlled acceleration and deceleration.

For mixers and production machinery, it allows motor speed to be matched to the actual production requirement.

For automated equipment, the embedded industrial communication capability allows the drive to become part of the larger machine-control system.

Its approximate 424.2 × 134.5 × 212 mm dimensions and approximately 8 kg equipment weight also make it considerably easier to install than high-power PowerFlex configurations with larger frames.

The main advantages can therefore be summarized as:

compact Frame 2 construction, 240 VAC three-phase operation, 22 A normal-duty capacity, flexible motor-control modes, integrated dynamic braking, industrial Ethernet communication, adjustable acceleration and deceleration, and useful diagnostic functions.

For final engineering, replacement or purchasing, the complete catalog number 20G11NB022JA0NNNNN should be retained exactly because the individual catalog-number characters define the drive configuration.

The product is best suited to industrial users who need a flexible variable-speed drive for pumps, fans, conveyors, mixers, material-handling systems and general machinery where a compact but advanced AC drive is required.
