Parameter Descriptions
3-33 Sync. Mode & Start Behavior
Option: Function:
[11] Marker Catch Select this option to accelerate the
Up follower to reach the position of
the previous master marker during
marker synchronization.
[12] Marker Slow Select this option to decelerate the
Down follower to align with the
subsequent master marker during
marker synchronization.
[13] Mar. Dis. Meas. Select this option to measure
Fo. follower marker distance while
synchronizing without marker
correction, when the master is
running. The measured follower
marker distance is set in
parameter 3-34 Marker Distance.
[14] Mar. Dis. Meas. Select this option to measure
Ma. master marker distance while
synchronizing without marker
correction, when the master is
running. The measured master
marker distance is set in
parameter 3-34 Marker Distance.

Enter the approximate distance
between 2 markers. To measure the
marker distance for follower or
master marker, select the
corresponding marker measuring
function in parameter 3-33 Sync.
Mode & Start Behavior.
Marker distance is in position units
as defined in parameter group 17-7*
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 in
order to utilize the marker window
function.

Ensure 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.
