10.6 Communication via SINAMICS Link
10.6.3 Configuring and commissioning
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. Set parameter p2037 of the drive objects to "2" (do not freeze setpoints).
4. Assign the nodes in parameter p8836 to the SINAMICS Link node number. The first
Control Unit is always assigned the number 1. Node number 0 means that for this Control
Unit SINAMICS Link has been shut down. Observe the specifications under "Topology".
5. Set the Control Unit parameter p0009 = 0 (ready).
6. Then execute a "Copy RAM to ROM".
7. Carry out a POWER ON (switch off the Control Unit and switch on again).
Sending data
In this example, the first node has Control Unit 1, two drive objects, drive 1 and drive 2.
Proceed as follows to send data:
1. For each drive object, in their associated parameters p2051[0...15], define which data
(PZD) should be sent. The data is simultaneously reserved in the send slot of the
p8871[0...15].
2. You must enter double words in p2061[x]. Double word data is simultaneously written to
p8861[0...15].
3. For each drive object, allocate the send parameters in p8871[0...15] to a send slot of its
own node.
