20-COMM Carrier Adapters
The following table details what 20-COMM adapters can be used with the
PowerFlex 750-Series drives.
20-COMM Adapters Compatible with the PowerFlex 750-Series Drives
Most legacy communication adapters (20-COMM) can be used with the
PowerFlex 755 drives (with these restrictions):
• Frame 1 - We recommend that you install catalog number
20-750-20COMM-F1 communication carrier card in port 4. Port 5 is not
accessible when this module is installed.
• Frames 2 and larger - We recommend that you install catalog number
20-750-20COMM communication carrier card in port 6. If you use port 4
or 5, the adjacent left port is inaccessible to other option modules and can
interfere with network cable connections. For details, contact
Rockwell Automation technical support.
