(2) Positioning Operation (ST0, ST1, LS0, LS1, LS2, PE0, PE1, PE2)
Positioning is at the start point when Movement Signal 1 ST0 is ON, and at the end point
when Movement Signal 2 ST1 is ON.
When both ST0 and ST1 are ON (Note 1) , the positioning is at the intermediate point. If turning
the both signals OFF (Note 1) during the operation, the actuator decelerates and stops.

• Intermediate Point Indication Both ON : Positioning at intermediate point
when both ST0 and ST1 are ON, and
decelerate and stop when both OFF
during an operation.
• Intermediate Point Indication Both OFF : Positioning at intermediate point
when both ST0 and ST1 are OFF,
and decelerate and stop when both
ON during an operation.
Note 2 If “Use Pressing Function” is selected in the initial setting and the positioning is
performed, this signal becomes the positioning complete (LS0 to 1 ĺ PE0 to 1).
