MCO 305 Design Guide
If the Start point is greater than the Stop point,
then the engaging/disengaging operation will "wrap
around" the master cycle.
If no start stop points have been defined, the slave
will be engaged with the set maximum velocity in
the case of SYNCCSTART.
The order of the points in each pair is important
and will automatically be taken into account by the
run direction: When moving forward, the
synchronization begins at the Start point and is
finished at the Stop point. When moving backward,
it begins at the Stop point and is finished at the
Start point.
If the program is closed without the explicit
command SYNCCSTOP pnum slavepos, the second
point pair will always be used for disengaging.
Adding, Deleting, and Displaying Start Stop Points and Progression
Start Stop points can be added by clicking the
"Add" button in the Start Stop Points table. This will
display the dialog for adding points. Points must be
specified as pairs of start and stop values and mul-
tiple pairs can be defined at the same time. Unlike
Fix points which must be ordered, Start Stop pairs
can be entered in any order.
Start Stop points can be deleted by clicking on
desired point in the Start Stop Points table to select
it. Then press the [Del] key.
Start Stop points can be modified by double click-
ing on the desired point in the Start Stop Points
table. This will display the dialog for modifying
points:
You can visually display the Start Stop points and the engage and disengage curves in the curve profile.
Activate Start Stop. Yellow flags indicate the point pairs for the engaging and disengaging in the
synchronization. The Start point will be labeled with "a" and have a yellow arrow. The Stop point will be
labeled with "b" and have a red arrow. If a Start Stop pair has been selected by clicking on it in the Start
Stop Points table, then that pair will be displayed with red flags.
In order to display the engage and disengage curves activate either
or both. Then select the Start Stop pair of interest by clicking on it in the Start Stop Points table.
NB!:
When the master moves forward engaging is shown by the engage path and disengaging is shown
by the disengage path.
When the master moves backward, engaging is shown by the Disengage path and disengaging is
shown by the Engage path!
