(3) Automatic-teaching (set by a moving workpiece)
Measure the sensing distance while the key is held down, and set the value between the minimum and maximum distance
values as the threshold value.
Before making this setting, make sure that the MODE key setting is set to [AUTO]. The default setting is [2PNT]. Refer to
"Function Transition Charts" in "5. Function Overview."
(4) Position teaching
Set the sensing distance of the workpiece as the threshold value.
Before making this setting, make sure that the MODE key setting is set to [PPT]. The default setting is [2PNT]. Refer to
"Function Transition Charts" in "5. Function Overview."
• Teaching error display
An error occurs if the following is displayed on the sub-display after teaching is executed.
Execute teaching again.
OVER error
The taught distance is outside the sensing range.
Check the position of the workpiece, and then execute teaching again.
NEAR error
The difference between the maximum taught distance and the minimum
taught distance is too small.
Check the teaching position, and then execute teaching again.
(This error occurs with teaching with and without a workpiece, and
automatic-teaching.)
"AUTO" is displayed as the sub-
display value, and sampling of
the sensing distance is started.
