[6] Operation when Operation Pattern is “2-Point Stop (2-Point Positioning)”
(1) Home Return (ST0, HEND, LS0, LS1, PE1)
If the home-return operation is not performed with the operation panel, it will be performed
with Movement Signal 1 to the first end point ST0. The actuator moves to the end point after
home-return and then stops (for positioning).
Move signal 1 ST0
Home return completion HEND
Detection of end position LS1 (Note 1)
Actuator operation
Reverse at
mechanical end
Home position End position
Note 1 If “Use Pressing Function” is selected in the initial setting, this signal becomes
the end point positioning complete signal PE1.
(2) Positioning Operation (ST0, LS0, LS1, PE0, PE1)
Positioning is at the end point when Movement Signal 1 ST0 is ON, and goes back to start
point (positioning) when it is OFF.
Move signal 1 ST0
Detection of start position LS0 (Note 1)
Detection of end position LS1 (Note 1)
Actuator operation
End position Start position
Note 1 If “Use Pressing Function” is selected in the initial setting and the positioning is
performed, this signal becomes the positioning complete (LS0 ĺ PE0, LS1 ĺ
PE1). If the operation pattern is “3-point stop (3-Point Positioning)”
