Mar. meas.
catch up
Continuous measurement of distance between master and follower marker. At every follower marker the
distance is measured to the latest master marker. The result of the measurement is updated in parameter
18-24 Marker Pos. Offset in position units as defined in parameter group 17-0* Position Scaling.

Enter the approximate distance between 2 markers. To measure the marker distance for follower or master marker, select the corre-
sponding marker measuring function in parameter 3-33 Sync. Mode & Start Behavior. Marker distance is in position units as defined in
parameter group 17-1* Position Scaling. The value is converted to the position units of the follower using the master scale set in
parameter 3-22 Master Scale Numerator and parameter 3-23 Master Scale Denominator. Configure the marker distance to utilize the
marker window function.
Parameter 3-35 Marker Window

Default value: 0 CustomReadoutUnit2
Parameter type: Range, 0 - par. 3-34 CustomReadoutUnit2
Setup:
Conversion index: 0
Data type: Int32
Change during operation:
N O T I C E
This parameter is only available with software version 48.XX.
Make sure to configure parameter 3-34 Marker Distance. The marker window function is only active when the marker distance is set.
Enter the window size around the expected marker position where the marker is accepted. The marker window is used for both
master and follower marker and the position units are as defined in parameter group 17-7* Position Scaling. Master position value is
converted to follower position units using the master scale set in parameter 3-22 Master Scale Numerator and parameter 3-23 Master
Scale Denominator.
