The internal data transfer takes place with write access to
subindex 1. If subindex 2 should also be used, it must be written
before subindex 1.

: interpolation_time_period
The synchronisation interval can be set via the object record
interpolation_time_period
.
Via
ip_time_index
, the unit (ms or 1/10 ms) of the interval is established, which is
parameterised via
ip_time_units
. To achieve synchronisation, the complete controller
cascade (current, speed and position controller) is synchronised up to the external cycle.
A change in the synchronisation interval is therefore effective only after a reset. Therefore,
if the interpolation interval is to be changed via the CAN bus, the parameter set must be
saved (see chapter 6.1) and a reset performed (see chapter 5.6) so that the new
synchronisation interval becomes effective. The synchronisation interval must be
maintained exactly.
