1-axis linear control
In "1-axis linear control" ("[Da.2] Control system" = ABS linear 1, INC linear 1), one motor is used to carry out position
control in a set axis direction.
(1) 1-axis linear control (ABS linear 1)
(a) Operation chart
In absolute system 1-axis linear control, positioning is carried out from the current stop position (start point
address) to the address (end point address) set in "[Da.6] Positioning address/movement amount".
Ex.
When the start point address (current stop position) is 1000, and the end point address (positioning
address) is 8000, positioning is carried out in the positive direction for a movement amount of 7000 (8000-
1000).
(b) Positioning data setting example
The following table shows setting examples when "1-axis linear control (ABS linear 1)" is set in positioning data
No. 1 of axis 1.
Refer to

Page 152, Section 5.3 for information on the setting details.
Setting item Setting example Setting details
Axis 1 positioning
data No. 1
[Da.1] Operation pattern Positioning complete
Set "Positioning complete" assuming that the next positioning data will not
be executed.
[Da.2] Control system ABS linear 1 Set absolute system 1-axis linear control.
[Da.3] Acceleration time No. 1
Designate the value set in "[Pr.25] Acceleration time 1" as the acceleration
time at start.
[Da.4] Deceleration time No. 0
Designate the value set in "[Pr.10] Deceleration time 0" as the
deceleration time at deceleration.
[Da.5] Axis to be interpolated  Setting not required. (Setting value will be ignored.)

Setting not required. (Setting value will be ignored.)
[Da.8] Command speed 6000.00mm/min Set the speed during movement to the positioning address.
[Da.9] Dwell time 500ms
Set the time the machine dwells after the positioning stop (pulse output
stop) to the output of the positioning complete signal.
[Da.10] M code 10
Set this when other sub operation commands are issued in combination
with the No. 1 positioning data.
