10-2 2D Comparator Mode
The 2D (Two dimensional) comparator mode performs a two dimensional comparison by switching
the 5-level comparator with the upper and lower limit values that are preset for each level.
10-2-1 Switching the comparator
Two switching methods are available.
By COMP 1 to COMP 5 inputs (
f-16 4
or
5
)
Switching is performed by the change in position.
Connect the position detection switch to the COMP 1 to COMP 5 input terminals. Set function
mode
f-16
(Comparator mode) to “
4
” or “
5
”.
By time control (
f-16 6
or
7
)
Switching is performed by the change in time.
In addition to the upper and lower limit values, set the starting and ending time to each level of the
comparator. Set function mode
f-16
(Comparator mode) to “
6
” or “
7
”.
10-2-2 Detailed description of the 2D comparator mode
Turn the COMP ON input terminal ON to start a comparison. With the COMP ON input terminal
turned OFF, no comparison or result output is performed. To use the COMP ON input terminal, set
the function mode
f-18
(COMP ON) to “
1
(Used)”.
The relation between the output results, the indicator color and the output condition for each level
is as shown below:

5-level comparator indicators
A number is written above each
z
to
indicate the level.
When the COMP ON input terminal is
turned ON, the
z
indicator, at the level
where the comparison is performed
currently, starts to blink. Then, the
indicator turns to red for HI, green for OK
and orange for LO. When the comparison
moves to another level, the indicator
stops blinking and illuminates in the color
of the result.
NG indicator
In the 2D comparator mode, the NG
indicator turns on when any one of the
5-level comparison results is HI or LO.
The NG indicator is red when HI, and
orange when LO. When the comparison
results of levels 1 through 5 have HI and
LO, it will be red.
