Operation
6.10 Communication via SINAMICS Link
Bus cycle and number of nodes
The bus cycle of SINAMICS Link can be operated, synchronized with the current control
cycle, or not synchronized.
● Synchronized operation is set with p8812[0] = 1.
Up to 16 stations with 500 µs bus cycle can communicate with one another via
SINAMICS Link. To do this, the maximum number of nodes must be set with p8811 = 16.
Up to 64 stations with 1000 µs or 2000 µs bus cycle can communicate with one another
via SINAMICS Link. To do this, the maximum number of nodes must be set with
p8811 = 64.
● In non-synchronized operation (p8812[0] = 0), the PZD sampling time (p2048/p8848) is
effective instead of the bus cycle (p8812[1]).
After changing over parameter p8811 and p8812, a POWER ON must be carried out to
accept the settings.
