[Statuses of position detection output signals when the push function is not used]
Even when the servo is turned off, as long as the actuator is positioned within the positioning band
(parameter No. 1) the start point detection signal (LS0), end point detection signal (LS1) or intermediate
point detection signal (LS2) will turn ON according to the applicable position, just like when a sensor is used.
Accordingly, the position detection signal that has turned ON will remain ON after completion of positioning
unless the actuator moves.
[Status of position complete signals when the push function is used]
In push-motion operation, the servo does not turn off automatically while the actuator is pushing the work
part.
If the actuator has missed the work part, the servo turns off automatically.
Once the servo turns off, a position complete status is lost. Accordingly, the push complete signal 0 (PE0),
push complete signal 1 (PE1) and push complete signal 2 (PE2) will all turn OFF regardless of the stop
position.
Caution: No holding torque is applied in the auto servo OFF mode. Since the actuator will move in
this condition if an external force is applied, pay due attention to contact and safety when
setting any operation involving auto servo OFF.
To change the travel speed for operation pattern (PIO pattern) 1, set the position at which to change the
speed, and the new speed, in addition to the position data.

To change the position data for operation pattern (PIO pattern) 2, set the new position data for forward end
or backward end, in addition to the current position data for forward end position or backward end position.
x If CN1 (Operation switching signal) is OFF, the position data for forward end position becomes [1]:
Forward end position.
If the signal is ON, the position data becomes [3]: Forward end position.
x If CN1 (Operation switching signal) is OFF, the position data for backward end position becomes [0]:
Backward end position.
If the signal is ON, the position data becomes [2]: Backward end position.
