● The ports of the CBE20 must be interconnected strictly in accordance with the previous
diagram. You must always connect port 2 (P2) of node n with port 1 (P1) of node n + 1.
● In the "SINAMICS Link" mode, ports 3 and 4 of the CBE20 can only be used to connect to
the STARTER commissioning tool or Startdrive.
Corresponding parameters for IF1 or IF2

Configuring and commissioning
Note
When using SINAMICS Link, the memory card must remain inserted in the CUD.
p8835 cannot be set to 3 if it is not inserted.
When commissioning, proceed as follows:
1. Set the Control Unit parameter p0009 = 1 (device configuration).
2. Set the Control Unit parameter p8835 = 3 (SINAMICS Link).
3. Using p8839, define which interface should be used (for example for IF1: p8839[0] = 2).
