1) Teaching settings
(1) Teaching with and without a workpiece
Set two points one with a workpiece and another without a workpiece to be respectively sensed, and set the point between
these two points as the threshold value. This setting can be made in both of the RUN and SET modes.
When this setting is made in the RUN mode, make sure that the "MODE key setting" function is set to [2PNT]. The default
setting is [2PNT]. Refer to "Function Transition Charts" in "5. Function Overview."
(2) Teaching without a workpiece (background teaching)
Set the threshold value referenced to a state in which a workpiece is not present (background).
Set the threshold value 10% in front the sensing range width referenced to the distance in a workpiece absent state.
Example: In the case of a 50 to 300 mm type, set the threshold value about 25 mm in front.
