● The numbers of the various nodes are entered into parameter p8836[0...63] in ascending
● Gaps in the numbering are not permitted.
● The node with the number 1 is automatically the sync master of the communication link.

Configuring and commissioning

Commissioning
When commissioning, proceed as follows for the Control Unit:
● On the CU, set parameter p0009 to 1 (unit configuration).
● On the CU, set parameter p8835 to 3 (SINAMICS Link).
● Using p8836, assign node numbers to the nodes (the first CU is always assigned the
● On the CU, set parameter p0009 to 0 (unit configuration).
● Save the changes saved in the RAM in a non-volatile fashion.
● Perform a Power ON (switch-off/switch-on).
