9 MAJOR POSITIONING CONTROL
9.2.2 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)
Operation chart
In absolute system 1-axis linear control, addresses established by a machine OPR
are used. 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".
0
1000
8000
Positioning control (movement amount 7000)
Start point address
(current stop position)
End point address
(positioning address)
Example
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)
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.

Da.1
Operation pattern
Positioning
complete
Set "Positioning complete" assuming the next positioning data will not
be executed.
Da.2

Set the positioning address. (Assuming "mm" is set in "
Pr.1
Unit
setting".)
Da.7
Arc address
–
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.

Set this when other sub operation commands are issued in
combination with the No. 1 positioning data.
Refer to Section 5.3 "List of positioning data" for information on the setting details.
