CAN address with CMMD-AS:
The setting for the CAN address of the first controller is
entered in CMMD-AS. The CAN address of the first controller
+ 1 is automatically assigned to the second controller.
When the CMMD-AS is selected, only one controller of the
CMMD-AS is assigned to an axis. When the second controller
of the CMMD-AS must also be assigned to an axis, a CMMD
must also be assigned to this axis.
For more information, refer to the documentation of the
