Measuring from a Reference Point on the Machine Frame
With or without linear units a reference point can be defined. Then, all position vaules will
refer to this reference point. The reference point can be on the machine frame, for example
(fig. 21).

If measuring from a reference point should be activated, the parameters
base distance left
and
base distance right
have to be set as follows (ref. to „9. Parametrization“):
•
Execute special function
Freerun
(fig. 16) to move the sensors to the reference positions of
the linear units.
•
In parameter
Base distance left
set the distance between reference point (i.e. machine
frame) and axis of left sensor (fig. 21).
•
In parameter
Base distance right
set the distance between reference point (i.e. machine
frame) and axis of right sensor (fig. 21).
Note
The reference point must always have a greater distance to the web edge than the sensor
has (fig. 21).
Using center guide, the same reference point is taken for left and right; it is incidental if the
reference point ist left-side or right-side of the web.
If measuring from a reference point is not needed, the parameters
base distance left
and
base distance right
have to be set to Zero. In this case, the position values are referring to
the sensor positions. If linear units are used, the position values are referring to the
reference positions of the linear units (fig. 21).
