Operation
6.9 Communication via SINAMICS Link
Inverter chassis units
276 Operating Instructions, 07/2016, A5E00331449A
Note
The parameters listed in the following description refer to the assignment of SINAMICS Link
to IF1. If you assigned SINAMICS Link to IF2, then you find the corresponding parameters in
the previous c
hapter.
In this example, the first "Control Unit 1" node has two drive objects, "Drive 1" and "Drive 2".
Proceed as follows to send data:
1. If SINAMICS Link is assigned to IF1, then for each drive object, in its associated
parameter p2051[0...31], you define which data (PZDs) should be sent.
If SINAMICS Link was assigned IF2, then p8851 must be used for the setting. The data is
simultaneously reserved in the send slot of the p8871[0...31].
2. Enter the double words in p2061[x].
Double word data is simultaneously written to p8861[0...31].
3. For each drive object, allocate the send parameters in p8871[0...31] to a send slot of its
own node.
