Start of axis synchronisation
After mains connection and the initialisation phase, the synchronisation is started. After
the first sync telegrams have been received, it takes a few seconds until the system is
compensated. The duration of this process is basically determined by the interval of the
sync signals and the sync correction increment.
The CAN sync correction increment (C0363) indicates the increment used to extend or
shorten the control cycle (e.g. to shift the start time).
The lowest value preset by default can be left as it is. Only in unfavourable conditions (e.g.
if the sync master does not exactly comply with its cycle time) it may be necessary to
prolong the CAN sync correction increment so that the value in C4264 is reduced to a
minimum. Apart from that, a prolongation has a more negative effect on the drive
characteristics.
