Commissioning Manual, 07/2007, 6FC5397-2AP10-3BA0
– Instead of the drive components macro call-up, you carry out the following work steps
in order to match the topology:
NX p97=1 (actual topology accepted into setpoint topology),
NX p9=0 (restart of the controller),
wait until NX p3988>=680.
– For the drive object assignment for the PROFIBUS connection, the list of the drive
objects in the parameter p978 for the first motor module begins with "2" (no
ALM/infeed without DRIVE-CLiQ).
The following table illustrates, using the example of an SINAMICS S120 component
structure (one NX (CU), three motor modules (MM)), the assignment of the NCK machine
data for input/output address/message frame/setpoint/actual value.

– Under "General MD" in the "MD13120 [1] CONTROL_UNIT_LOGIC_ADDRESS", you
enter the input/output address for the NX (e.g. address "6516").
You have determined this address in the SIMATIC Manager in the HW Config via
"Object properties > Configuration > Details".
– The following general machine data is preassigned with a default value. No
adjustment is necessary here since these values correspond to those preassigned
values in the HW Config.
