5.8 Motion Control with PROFIBUS–DP (from SW 3.1)
The interpolation clock cycle (P1010) must be parameterized the
same for all axes.
The master application clock cycle T
ple of the interpolation clock cycle.
T and T must be the same for all axes.
I O
T must be less than or equal to 16 ms.
DP
For masters, which cannot generate a master sign of life (e.g.
SIMATIC S7), T must be = to T
MAPC
ing in operation must be disabled using P0879.8 = 1.
Presently, there is no run level that is in synchronism with DP cycle
in S7 user programs. This means, that if axes are to be simulta-
neously started, in addition to the clock–synchronous PROFIBUS
operation, the "classic" SYNC mechanism must be used.
SYNC mechanism
––> refer to the documentation of the DP master SIMATIC S7
(SFC 11 "DPSYNC_FR")
The SYNC mechanism may only be activated after the drive has set
the status bit ZSW1.9 "control requested".

must be an integer multi-
