The leading axis-specific synchronization profile is defined by the "Synchronization
length" and "Desynchronization length" parameters.
Synchronization length Distance during synchronization
Desynchronization length Distance during termination of synchronism
For synchronization based on leading axis values, define a start or end value for
synchronization and a synchronization length ("Synchronization length" or
"Desynchronization. length") based on the control value.
A synchronization profile is determined. That is, a dynamic transition is calculated
independently of the dynamic response characteristic of the control value.
The velocities at the margins of the synchronization process are constant.
The synchronization length specified in the dialog forms the basis for the definition
of the synchronization range with reference to the control value. The cams are
synchronized by means of the technology functions "MC_GearIn" (gearing) or
"MC_CamIn" (camming), or "MC_GearInSuperImposed" (superimposing gearing),
or by starting camming with FB 441 "MC_CamInSuperImposed" superimposing
camming).
Input parameter Mode at the technology functions determines whether to fetch the
values for the synchronization profile from S7T Config (Mode = 0), or whether to
use the dynamic defaults of the block (Mode = 1).
Note
The synchronization profile is calculated only in relation to the synchronization
length and not in relation to the limitation in the following axis.
For this reason, the dynamic response limitation only occurs in the following axis.
