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.
Limitations for a slave axis
!
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).
