MCO 305 Design Guide
Interval Size and Interval Time (ms)
These values are only important if interpolation has been enabled. The interval size is the length of a single
interpolation interval in master units. It is derived from the number of intervals and the length of the
master cycle.
The interval time (in milliseconds) is derived from the interval size and the number of cycles of the master
per minute. This time should not be smaller than 30 milliseconds. 30 to 100 ms are suitable values.
Changes should be made in Curve Data → Number of Intervals in order to ensure a reasonable value.
Index Card Synchronization and Sync Marker
The axis synchronization parameters are of particular interest when working with curve profiles since they
affect the synchronization of the slave to the master. The relevant parameters are described below.
Syncfactor Master and Slave
The two parameters 33-10 and 33-11 Syncfaktor [Master:Slave] are used to determine the MU units in the
CAM control.
Marker Distance
Enter the distance of the sensor to the processing point: Parameter 33-17 Master Marker Distance and 33-
18 Salve Marker Distance. The position of the curve where the marker is detected is calculated from the
master marker position and the marker distance.
If → Master Marker or Slave Marker is enabled, then these positions will be shown as a green line in the
curve profile diagram.
Tolerance
This is the tolerance window for the appearance of the master marker 33-21 SYNCMWINM or the slave
marker 33-22 SYNCMWINS (Marker monitoring).
If → Master Marker or Slave Marker is enabled, then the tolerance window is shown as a green area in
the curve profile diagram.
