Configuring and commissioning

Commissioning
When commissioning, proceed as follows for the Control Unit:
● Set parameter p8835 to 3 (SINAMICS Link).
● Using parameter p8836, assign node numbers to the nodes (the first Control Unit is
● Then execute a "Copy RAM to ROM".
● Perform a POWER ON (switch-off/switch-on).
Sending data
Proceed as follows to send data:
● In parameter p2051[x], for each drive object, define which data (PZDs) should be sent.
● In parameter p8871, for each drive object, assign the send parameter to the send slot of
Receiving data
Proceed as follows to receive data:
Note
The first word of the receive data must be a control word, where bit 10 is set to 1. If this is
not the case, then you must deactivate the evaluation of bit 10 using p2037 = 2.
● Received data are saved in parameter r2050[x]/r2060[x].
● The address of the node from which the relevant PZD is to be read is defined in
● In parameter p8870[0 ... 15], the PZD is defined, which is read from the sent telegram

number 0 means that SINAMICS Link is shut down.
p2061[x] must be used for double word quantities.

p8871[1] = 2 and p8871[2] = 3.
parameter p8872[0 ... 15] (0 ≙ nothing is read in).
and is to be stored in its own receive slot, r2050 for PZD or r2060 for double PZD (0 ≙ no
PZD selected).
Note
For double words, 2 PZD must be read; e.g.: Read in a 32-bit setpoint, which is located
on PZD2+PZD3 for node 5, and map this to PZD2+PZD3 of its own node: p8872[1] = 5,
p8870[1] = 2, p8872[2] = 5, p8870[2] = 3
