Commissioning NC-controlled drives
6.9 Tips for commissioning the SINAMICS drives
p0978[7] = 2
p0978[8] = 0
p0978[n] = 0
PROFIBUS telegram 370 for the infeed (ALM) is not supported by SINUMERIK. However,
according to the SINAMICS rule, all DO from parameter p0101 have to be assigned in
parameter p0978. For this reason, the DO number of the infeed should be entered in index 9.
Note
The list of DO involved in process-data exchange is completed by entering the value "0".
The list of drive objects is already preassigned in the following sequence by the system upon
initializing the drive (acceptance of topology): ALM, 1st Motor Module ... n, CU; e.g. 2-3-4-5-1.
Components that do not communicate via PROFIBUS automatically have "255" preassigned to
them.
Example: Assigning drive objects
The following table shows on a SINAMICS S120 component structure the drive object
assignment for the drive parameters:
● One Control Unit (CU)
● One Active Line Module (ALM)
● Three Motor Modules
Assignment p0978[0...9] for supply with DRIVE-CLiQ connection:
Component
1. Motor Module
2. Motor Module
3. Motor Module
not found

not found
CU
ALM (only if protocol 370 is available)
not found
ALM (default setting for SINUMERIK)
1) Not active
2) Ends the exchange of PZD
The following table describes the assignment of the drive objects in p0978[0...9] for an infeed
without DRIVE-CLiQ connection. This assignment is also done for a drive group with NX
module.
