(10) Jump movement
The actuator is moved to the location of the position data transferred to the controller by
jump motion (arch motion). Before/after normal movement or continuous movement, the
Z-axis is moved up and down.
Motion sequence
㽲 Raise the Z-axis from the current position to the top position (Z = 0). (Motion of the Z-axis
only)
㽳 Movement is performed to above the target position by PTP motion while the Z-axis stays
at the top position. (Motion of the X-axis, Y-axis and R-axis only)
㽴 Lowering is performed to the target position. (Motion of the Z-axis only). When the Z-axis
offset value is set, the Z-axis stops before (above) the target position by the same
amount.
Z-axis offset value: Specify how many millimeters before the target position to stop the
Z-axis. No minus value can be input.
(Example) When the Z-axis target position is 100.000 mm and
the Z-axis offset value is 30.000 mm,
the Z-axis stops at the position of 70.000 mm.
