01
Product Identification
20G11NC011JA0NNNNN is a Frame 2 PowerFlex 755 drive for 400 V AC three-phase systems. It integrates EtherNet/IP communication with the 750-Series motor-control platform in a forced-air-cooled open-type assembly.
The catalog code identifies AC input with DC terminals, standard protection, filtered input, installed common-mode jumper, dynamic-braking transistor and a blank HIM position.

Functions
- Controls a compatible 400 V motor using the PowerFlex 755 drive platform.
- Provides embedded EtherNet/IP for controller integration and drive diagnostics.
- Supports 750-Series option expansion after slot and firmware compatibility are confirmed.
- Uses forced-air cooling within the specified Frame 2 installation environment.
- Switches an externally designed dynamic-braking circuit through the included DB transistor.
04
Applications
- EtherNet/IP-connected machine axes and process equipment within the 11.5 A rating.
- Frame 2 installations where normal- and heavy-duty selection both align with the 5.5 kW capacity.
- Panel-mounted pumps, conveyors, fans and general machinery using a 400 V supply.
- Filtered open-type drive installations with separately engineered enclosure protection.
- Direct-replacement review for the earlier AA0 catalog variant after system verification.
05
Lifecycle
- Rockwell Automation lists 20G11NC011JA0NNNNN as Active Mature.
- The discontinued 20G11NC011AA0NNNNN has this JA0 catalog number listed as its direct replacement.
- Before exchange, save parameters and record the motor, network address, I/O, option modules and braking circuit.
- Complete application, firmware and installation checks even when the lifecycle record identifies a direct replacement.
