Bus cycle and number of nodes
You can operate the bus cycle of the SINAMICS Link with the current controller cycle, either
synchronized or non-synchronized.
● You set synchronized operation with p8812[0] = 1. A maximum of 64 nodes can then
communicate with one another via SINAMICS Link. To do so, set the maximum number
of nodes with p8811 (project selection):
Number of nodes/
project no.
Number of PZD Bus cycle (µs)
64 16 1000 or 2000
16 16 500
12 24 500
8 32 500
● A maximum of 64 participants can communicate with one another via SINAMICS Link.
If you change one of the parameters p8811, p8812, p8835 or p8836, then you must carry out
