Introduction

The Allen-Bradley 20G11NE017AA0NNNNN PowerFlex 755 AC Drive is an air-cooled variable-frequency drive developed for industrial three-phase motor-control applications. It combines a 17 A normal-duty output rating with embedded EtherNet/IP communication, supporting motor-speed regulation and integration with PLC-based automation systems.

This Frame 3 drive is designed for 600 VAC three-phase applications and supports motor ratings of 15 HP under normal-duty operation and 10 HP under heavy-duty operation. Its configuration includes AC input with precharge, an integrated dynamic braking transistor, and EMC filtering. The common-mode capacitor jumper is removed, so the installation's grounding arrangement should be checked carefully.

The PowerFlex 755 series is suitable for conveyor systems, pumps, fans, processing machinery, and automated production equipment. Its communication capabilities help connect motor-control functions with industrial controllers, allowing drive operation to be incorporated into broader automation systems.

For maintenance and replacement projects, checking the complete catalog number is important. Input voltage, output current, motor-duty rating, braking requirements, and filter configuration should all be considered before installation. This AA0 catalog version has been discontinued, with 20G11NE017JA0NNNNN identified as its direct replacement.

Applications

The Allen-Bradley 20G11NE017AA0NNNNN PowerFlex 755 AC Drive is designed for industrial motor-speed regulation in applications that require stable operation, controlled acceleration, and integration with automated control systems. With a 17 A output rating and embedded EtherNet/IP communication, it supports a variety of medium-power motor-control tasks.

Typical applications include:

Conveyor Systems: Regulates motor speed in material handling, packaging, and automated transport equipment.
Pumping Stations: Adjusts pump speed to meet changing flow and pressure requirements.
Industrial Fans: Provides variable-speed operation for ventilation and air-handling systems.
Processing Machinery: Controls motors used in mixers, feeders, and production equipment.
Manufacturing Lines: Integrates motor operation with PLC-based automation and industrial communication networks.

Advantages

1. Embedded EtherNet/IP Communication

The integrated EtherNet/IP interface enables communication with compatible Allen-Bradley controllers and industrial automation systems, supporting coordinated control and drive monitoring.

2. 17 A Output Capacity

The drive provides a 17 A normal-duty output rating and an 11 A heavy-duty rating. This dual-rating design allows engineers to select the appropriate operating mode according to motor load and application requirements.

3. Integrated Dynamic Braking Transistor

The built-in braking transistor supports applications requiring controlled motor deceleration. An appropriately rated external braking resistor can be connected when dynamic braking is required.

4. EMC Filter Configuration

The drive includes an EMC filter. Its common-mode capacitor jumper is removed in this configuration, making it important to verify grounding arrangements and power-system compatibility before installation.

5. Forced-Air Cooling

The forced-air cooling design helps dissipate heat generated during operation. Maintaining adequate cabinet ventilation and unobstructed airflow is essential for reliable performance.

6. Flexible Industrial Integration

The PowerFlex 755 platform offers configurable motor-control and communication functions, making it suitable for integration into a wide range of industrial automation architectures.

Technical FAQs

Q1: What is the rated output current of the 20G11NE017AA0NNNNN?

The drive has a 17 A continuous output rating for normal-duty operation and an 11 A rating for heavy-duty operation. Select the operating duty according to the motor's rated current and application load.

Q2: What input power supply does this model require?

This model belongs to the 600 VAC three-phase input class. Verify the actual supply voltage and electrical installation requirements against the drive nameplate before connecting power.

Q3: What are the motor power ratings?

The listed motor ratings are 15 HP for normal-duty applications and 10 HP for heavy-duty applications. The correct rating depends on the required overload capability and operating conditions.

Q4: Does this drive support EtherNet/IP communication?

Yes. Embedded EtherNet/IP allows the drive to exchange commands, reference values, and operating information with compatible PLCs and other supported automation devices.

Q5: Does the 20G11NE017AA0NNNNN have a built-in braking transistor?

Yes. It includes an integrated dynamic braking transistor. An external braking resistor is required when the application uses dynamic braking, and its electrical ratings must comply with the manufacturer's specifications.

Q6: What does the removed common-mode capacitor jumper mean?

The common-mode capacitor jumper configuration affects the drive's electrical relationship to ground. Installation personnel should check the power distribution system and grounding requirements before commissioning the drive.

Q7: Can this PowerFlex 755 drive be controlled by a PLC?

Yes. A compatible ControlLogix or CompactLogix controller can communicate with the drive through EtherNet/IP. Correct network addressing, drive parameters, and controller configuration are necessary.

Q8: What can cause an overcurrent fault during acceleration?

Potential causes include excessive mechanical load, acceleration settings that are too aggressive, incorrect motor parameters, wiring problems, or an unsuitable current limit. Review the fault history and operating conditions before restarting.

Q9: How can overheating problems be reduced?

Check the cooling fan, cabinet ventilation, ambient temperature, airflow clearance, and accumulated dust. Also confirm that the motor load remains within the applicable drive rating.

Q10: Is the 20G11NE017AA0NNNNN still available as a current-production model?

This earlier catalog version has been discontinued. Rockwell Automation identifies 20G11NE017JA0NNNNN as its direct replacement. Before substitution, verify the filtering and common-mode capacitor configuration as well as the electrical and installation requirements.
