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.
