5.2 Teaching a User-Specific Switching Window
5.2.1 Parameter
Switching points work: This parameter comprises the currently employed beginning and end points of
the switching window. The beginning and end point of the desired switching
window can either be directly defined in the parameter (numerical teaching), or
it can be automatically set via the interim register when an object is being
taught. The parameter comprises two 16 bit components: Switching point A
and Switching point B.
- Unit:
0.1mm
- Factory setting: Switching point A = 50mm; switching point B = 400mm
Switching points interim: This parameter serves as a supplemental register to teach the switching points
for an object.
- Unit:
0.1mm
5.2.2 Commands
Teach-in switching point A: Command to teach switching point A. The taught value is transferred to the
interim register, Switching points interim.
Teach-in switching point B:
Command to teach switching point B. The taught value is transferred to the
interim register, Switching points interim.
Transfer switching points:
The switching points learned in the interim register, Switching points in-
terim, are transferred to the Switching points work work register and and
set to active.
5.2.3 Description
There are two methods which the user can employ to adjust the switching window of the FADK 14:
•
Numerical teaching: The beginning and end points of the switching window are written directly to the
Switching points work parameter;
•
Teaching an object: The beginning and end points of the switching window are learned for an object
by applying the corresponding measuring commands. If the object lies outside the original measuring
range, the minimum or maximum measuring distance are learned.
Switching points A and B define a switching window which, in turn, determines the state of the switch bits.
Switching points A and B are output as absolute distances from the leading sensor edge in 0.1 millimeter
increments.
Figure 4 illustrates all possible characteristic switching curves.
