Nominal
value
-999.999 - +999.999 [mm]
(default value 2.0[mm])
Set the nominal value, +tolerance and
-tolerance of the judgment reference.
Set the "Hi judg. val." and the "Lo judg. val."
along with the "Nominal val.", +tolerance and
-tolerance.
Hi judg. val. = (Nominal val.) + (+tolerance)
Lo judg. val. = (Nominal val.) - (-tolerance)
+ tolerance
- tolerance
0 - +999.999 [mm]
(default value 0.1[mm])
Hysteresis
width 0 - +999.999 [mm]
（
default value 0.05 [mm])
Set the "Hys. Width" (judgment hysteresis
width).
Set the judgment hysteresis width within a
range 50% smaller than the (+tolerance) -
(-tolerance).
●
Relationship of nominal value, tolerances, hysteresis width, high & low
judgment values
As shown in the following figure, the relationship between the nominal
value, tolerances, hysteresis width, high & low judgment values and the
ON/OFF of the output, is activated when the output is ON for the high
judgment value or the low judgment value.
(The same hysteresis width is used for both the high judgment value and
the low judgment value.)
