Warning
!
When superimposing the speed of the master and slave drives, a
resulting slave drive speed can be obtained which is greater than the
maximum speed P0102. For slave axes, the speed monitoring in
P1147, P1401:8 and P1405:8 applies.
Note
For coupled operation via PROFIBUS–DP, we recommend that internal
couplings are not used. Instead, the second drive should be
parameterized as subscriber (refer to Chapter 5.10).

SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
It is possible to have mixed operation of position reference value
sources within a drive group. For instance, drive A can receive its
setpoint via the angular incremental encoder and transfer this to
other drives via PROFIBUS–DP. The following secondary conditions
must be observed:
– The synchronous operation of the drive group is poor as a result
of the different data propagation times.
– There are differences in the position resolution between the indi-
vidual sources.
