3.8.4 Other Basic Operations
(1) Push operation
[1] Basic operation
As shown below, the actuator moves to the specified target position, and then moves at the specified push speed by
up to the specified positioning band while pushing the work part.
The moment the push force reaches a certain value during push movement, completion of push is recognized and
the position complete signal turns “1” (ON).
x Image of push direction
As shown above, when the actuator pushes from the start point to the target position the direction in which the coordinate
increases is defined as the positive (+) direction, while the direction in which the coordinate decreases is defined as the
negative (-) direction. Exercise caution because if the push direction is set incorrectly, the actuator will not operate correctly
and push the work part at a position offset toward the start point by the distance of “positioning band x 2.”
Speed
When the load is contacted, completion of push is recognized
and the position complete signal turns ON.
