“Push & hold operation”
The set value defines the maximum distance the actuator will push the work
part in the push & hold mode upon reaching the target position.
Consider the mechanical variations of the work part and set an appropriate
positioning band so that positioning will not complete before the actuator
contacts the work part.
(8) Zone+/– x Define the zone in which the zone output signal turns ON.
For added flexibility, different values can be set for each target
position.
[Setting example]
The position complete signal turns ON here, because the
actuator has contacted the load and the controller has
determined that the push & hold operation has completed.
