AC DRIVE7552 CATALOG NUMBERS
Product Description
For compact networked motor feeders, Allen-Bradley 20G11ND2P1JA0NNNNN and 20G11ND5P0JA0NNNNN are PowerFlex 755 AC drives with embedded EtherNet/IP. Each drive converts a 480 V three-phase supply into controlled motor output and uses its embedded network interface to receive commands and references and to return operating status to the automation system.
Both 20G11ND2P1JA0NNNNN and 20G11ND5P0JA0NNNNN share Frame 2 open-type hardware, AC input with DC terminals, filtered forced-air construction, a DB transistor and a blank HIM selection. Their functional architecture is the same, but their output-current and motor-power classes differ, so the motor load—not the common frame or network port—determines which catalog number is used.

Embedded EtherNet/IP Connectivity
PowerFlex 755
The network interface carries control information while the power stage remains responsible for motor energy.
Status channel
Operating state, feedback values and diagnostic information return over the same network connection to the controller.
Power separation
Network data does not carry motor power; line and motor conductors remain on the drive power terminals and follow their own routing.
Small-Motor Output Selection
Two drives share one frame yet serve different motor-current requirements.
Lower-current feeder
The 2.1 A catalog number covers the smaller motor class and retains its own normal- and heavy-duty ratings.
Higher-current feeder
The 5 A catalog number increases available motor output without changing the shared Frame 2 mechanical platform.
Rating discipline
The selected current and duty class must match the motor and overload requirement; network capability does not make the power ratings interchangeable.
Frequently Asked Questions
A controller must send speed references over EtherNet/IP. What extra communication option is required for 20G11ND2P1JA0NNNNN / 20G11ND5P0JA0NNNNN?
No add-on EtherNet/IP module is required. Both catalog numbers include the embedded network interface for configured command, reference and status exchange.
One Frame 2 position is available in the panel. Does that make 20G11ND2P1JA0NNNNN / 20G11ND5P0JA0NNNNN interchangeable?
No. They share the Frame 2 outline, but their output-current and motor-power ratings differ. The chosen drive must still match the motor current and duty class.
Existing motor cables and branch protection were sized for 20G11ND2P1JA0NNNNN. Can they be retained automatically with 20G11ND5P0JA0NNNNN?
No. The shared voltage class and frame do not equal the same output current. Cable and protective-device selection must be checked for the individual catalog number.
Regenerative stopping is required with 20G11ND2P1JA0NNNNN / 20G11ND5P0JA0NNNNN. Which part of the braking path is not supplied?
Both drives include a DB transistor and DC terminals, but neither includes the external braking resistor. That branch must be selected for the chosen drive and deceleration energy.
The available fault-current study approaches the drive rating. How should the 200 kA value for 20G11ND2P1JA0NNNNN / 20G11ND5P0JA0NNNNN be interpreted?
It is the maximum short-circuit rating for an applicable protected installation, not a replacement for branch protection. The required protective-device combination remains part of the system design.
