Limitations:
● Within a telegram, it is not permissible that a PZD is sent or received twice; otherwise
● It is not possible to read in its own send date, otherwise alarm A50006 is output.
● The maximum number of PZD that can be received and sent depends on the drive object.
Transmission time
With SINAMICS Link, a transmission time of 1000 µs is possible (with a max. controller cycle
of 500 µs; synchronous bus cycle, 500 µs).
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.
● In non-synchronized operation (p8812[0] = 0), the PZD sampling time (p2048/p8848) is
After changing over parameter p8811 and p8812, a POWER ON must be carried out to
accept the settings.

alarm A50002 or A50003 is output.
The number of PZD that can be evaluated corresponds to communication according to
PROFIdrive.
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.
