(Example) Repetition of ST1 → ST2 → ST1 →• • •
Insert timer Δt if necessary.
Δt : Time required to certainly reach the target position after the position sensing output LS1 or 2 is turned on.
[Example of stop position when the ST* signal is turned OFF by the LS* signal]
If the positioning width is set at a position before the original deceleration start position,
the actuator cannot reach the target position.
