The Allen-Bradley 20G11ND040AA0NNNNN is a PowerFlex 755 variable frequency drive designed for 380–480 VAC three-phase industrial power systems. It provides a normal duty motor rating of 22 kW (30 HP) with 40 A output current, supporting appropriately sized variable-speed AC motor applications.
The drive also offers a heavy duty rating of 18 kW (25 HP) with 34 A output current. These separate duty ratings help engineers select the appropriate drive configuration for the torque and overload requirements of the connected machine.
The PowerFlex 755 platform includes an integrated EtherNet/IP interface for connection to compatible industrial automation networks. Supported control and monitoring functions enable integration with Rockwell Automation Logix controllers and drive-management software.
An internal dynamic braking transistor supports appropriately engineered braking arrangements. Applications requiring resistor-based dynamic braking must use a correctly selected external braking resistor and associated protection based on the motor and load characteristics.
This catalog number specifies an EMC-filtered configuration with the common-mode capacitor jumper removed. The exact grounding, motor cable and filtering installation requirements should be checked against the PowerFlex 750-Series documentation.
The air-cooled Frame 3 drive has an IP20 open-type enclosure and approximate dimensions of 454 × 190 × 212 mm. The catalog configuration does not include an operator keypad, so any required Human Interface Module must be selected separately.

What is the Allen-Bradley 20G11ND040AA0NNNNN?
It is a Rockwell Automation PowerFlex 755 air-cooled AC variable frequency drive designed for 480 V-class three-phase industrial motor applications, with a normal duty rating of 22 kW (30 HP) and 40 A.
What is the input voltage rating?
The drive is designed for a nominal 380–480 VAC three-phase electrical supply. The exact permitted voltage tolerance and installation requirements should be confirmed using the applicable manufacturer documentation.
What is the normal duty power rating?
The manufacturer and product datasheet identify a 22 kW (30 HP) normal duty motor rating with 40 A rated output current.
What is the heavy duty power rating?
The heavy duty rating is 18 kW (25 HP), with a rated output current of 34 A. Motor selection must account for the intended load profile and overload conditions.
Why does the drive have both normal duty and heavy duty ratings?
Normal duty and heavy duty ratings represent different permitted operating-load conditions. Heavy duty applications can require greater overload capability, which results in a lower permissible continuous current and motor power rating.
Does the 20G11ND040AA0NNNNN support EtherNet/IP?
Yes. The PowerFlex 755 includes an integrated EtherNet/IP communication port for compatible industrial network integration, parameter access and drive monitoring.
Does this drive include a keypad or Human Interface Module?
No. The catalog configuration is specified without a keypad. A compatible Human Interface Module can be selected separately when local display and parameter-entry functions are required.
Does the drive have an internal braking transistor?
Yes. The manufacturer specifies an internal dynamic braking transistor. External braking resistors, if required, must be selected according to the drive and application design requirements.
Does this model include an EMC filter?
Yes. The manufacturer identifies this catalog configuration as EMC-filtered, with the common-mode capacitor jumper removed. EMC performance depends on the complete installation, including grounding and cable routing.
What is the enclosure protection rating?
The drive is a Frame 3, IP20 open-type unit. It is intended for installation inside an electrical cabinet suitable for the operating environment.
What are the physical dimensions?
The listed dimensions are approximately 454 mm high, 190 mm wide and 212 mm deep, with a weight of approximately 12 kg. Allow additional space for ventilation, wiring and maintenance access.
Does the PowerFlex 755 support PID control?
Yes. The PowerFlex 755 series provides PID control functionality that can be configured for supported process-control applications such as pump and fan systems.
Can this drive be integrated into a PLC-controlled system?
Yes. Its built-in EtherNet/IP communication interface supports integration with compatible Rockwell Automation Logix controllers. Verify controller firmware, software profiles, drive parameters and network configuration before commissioning.
Is the 20G11ND040AA0NNNNN discontinued?
Yes. Rockwell Automation lists the product as discontinued effective June 30, 2024. Its lifecycle status should be considered when maintaining existing installations or planning system upgrades.
What is the manufacturer-listed replacement?
Rockwell Automation identifies 20G11ND040JA0NNNNN as a direct replacement. Before installation, verify physical fit, terminal arrangements, communication settings, firmware, drive parameters and electrical compatibility with the existing system.
What should be checked before ordering?
Confirm the complete catalog number 20G11ND040AA0NNNNN, PowerFlex 755 series, 480 V-class three-phase input, 40 A normal duty and 34 A heavy duty ratings, Frame 3 IP20 enclosure, built-in EtherNet/IP interface, EMC-filtered configuration, internal braking transistor, absence of a supplied keypad and the exact requirements of the connected motor and industrial control system.
