(2) 1-axis linear control (INC linear 1)
(a) Operation chart
In incremental system 1-axis linear control, positioning of movement amount set in "[Da.6] Positioning
address/movement amount" is carried out from the current stop position (start point address). The movement
direction is determined by the sign of the movement amount.
Reverese direction
Movement direction for
a negative movement amount
When the start point address is 5000, and the movement amount is -7000, positioning is carried out to the
Ex.
-2000 position.
-3000

Setting details
Set "Positioning complete" assuming that the next positioning data will not
be executed.
Set incremental system 1-axis linear control.
Designate the value set in "[Pr.25] Acceleration time 1" as the acceleration
time at start.
Designate the value set in "[Pr.10] Deceleration time 0" as the deceleration
time at deceleration.
Setting not required. (Setting value will be ignored.)
Set the movement amount. (Assuming "mm" is set in "[Pr.1] Unit setting".)
Setting not required. (Setting value will be ignored.)
Set the speed during movement.
Set the time the machine dwells after the positioning stop (pulse output
stop) to the output of the positioning complete signal.
Set this when other sub operation commands are issued in combination
with the No. 1 positioning data.
