Explanation of the Sensor Configuration
Parameters and commands can be used to configure the sensor functionalities. The following sections
provide a detailed description of the various configuration options.
5.1
Teaching a User-Specific Measuring Range
5.1.1
Parameter
Measuring range work:
This parameter covers the currently used beginning and end values for the
measuring range. The beginning and end values can either be entered directly
into the parameter (numerical teaching), or they can be automatically set via
the interim register to teach an object the parameter comprises two 16 bit
components: Measuring range limit A and Measuring range limit B.
-
Unit:
0.1mm
-
Factory setting:
30 ... 200mm
Measuring range interim:
This parameter serves as a supplemental register to teach the measuring
range for an object.
-
Unit:
0.1mm
5.1.2
Commands
Teach-in measuring range limit A:
Command used to teach measuring range limit A. The taught value is
transferred to the interim register, Measuring range interim.
Teach-in measuring range limit B:
Command used to teach measuring range limit B. The taught value is
transferred to the interim register, Measuring range interim.
Transfer measuring range:
The measuring range learned in the interim register, Measuring
range interim, is transferred to the Measuring range work register
and is set to active.
5.1.3
Description
There are two methods which the user can employ to adjust the measuring range of the UNxK 09:
Numerical teaching: The beginning and end values of the measuring range are written directly to the
Measuring range work parameter;
Teaching an object: the beginning and end values of the measuring range 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.
The measuring value between measuring value limits A and B is output as a relative value between 0 and
4095. Measuring value limits A and B are output as absolute distances from the leading sensor edge in 0.1
millimeter increments. Figure 2 illustrates possible characteristic measuring value curves.
