MCO 305 Design Guide
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!
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 end at the Stop point.
When moving backward, it begins at the Stop point and ends at the Start point.
A maximum of 25 Start Stop point pairs can be defined. This is useful, for example, to define multiple starts
and stops in a cycle in order to account for different situations during the start. Using the commands
"SYNCCSTART pnum" and "SYNCCSTOP pnum slavepos", you can determine in your program which point
pair is to be used.
If Start points = Stop points, the slave will be engaged with the set maximum velocity (i.e. without a curve)
as soon as the master has reached this point.
If Start point > Stop point, then the engaging/disengaging operation will "wrap around" the master cycle.
If no Start Stop points have been defined, then SYNCCSTART will cause the slave will be engaged with the
set maximum velocity.
If the program is closed without the explicit command "SYNCCSTOP pnum slavepos", then the second point
pair will always be used for disengaging.
Edit Start Stop points
Start Stop points are edited in the Start Stop table:
Adding Start Stop points
To add a new pair of Start Stop points, click the → Add button in the Start Stop Points table. This will
display the dialog for adding point pairs. Points must be specified as pairs of start and stop values and
multiple pairs can be defined at the same time. Unlike Fix points which must be ordered, Start Stop pairs
can be entered in any order.
Deleting Start Stop points
To delete a pair of Start Stop points, click on the Start Stop point pair in the Start Stop Points table and
then press the [Del] key.
Modifying Start Stop points
To modify a pair of Start Stop points, double-click on the Start Stop point pair in the Start Stop Points table.
This will display a dialog allowing the pair to be changed.
