6.10 Communication via SINAMICS Link
6.10.3
Configuring and commissioning
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. Using p8839, define which interface should be used (for example for IF1: p8839[0] = 2).
4. If SINAMICS Link is assigned to IF1, set parameter p2037 of the drive objects to 2 (do not
freeze setpoints).
If SINAMICS Link was assigned IF2, then p8837 must be used for the setting.
5. 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".
6. Check and/or correct the following parameters:
– p8811 must be identical for all nodes
– p8812[1] must be identical for all nodes
– p8812[0] may be different for local nodes
7. Set the Control Unit parameter p0009 = 0 (ready).
8. Then execute a "Copy RAM to ROM".
9. Carry out a POWER ON (switch off the Control Unit and switch on again).
Sending data
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 chapter.
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].
