9.5.3 Functional description
Before the drive controller can be switched to the interpolated position mode operating
mode, several settings have to be made.
These settings include the interpolation interval (interpolation_time_period), i.e. the time
interval between two sync telegrams, and the interpolation type
(interpolation_submode_select). Additionally, access to the position buffer must be
enabled via the buffer_clear object.
