[2] 1-axis linear control (INC linear 1)
Operation chart
In incremental 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 a position at the end of the movement amount set in "
Positioning address/movement amount". The movement direction is determined by
the sign of the movement amount.
Movement direction for
a negative movement amount
Example
When the start point address is 5000, and the movement amount is -7000, positioning is carried out to
the -2000 position.
Address after positioning control
-3000 -2000 -1000
Positioning control in the reverse direction (movement amount -7000)
Positioning data setting example
The following table shows setting examples when "1-axis linear control (INC linear
1)" is set in positioning data No. 1 of axis 1.

Set "Positioning complete" assuming the next positioning data will not
be executed.
Set incremental system 1-axis linear control.
Designate the value set in "
acceleration time at start.
Designate the value set in "
deceleration time at deceleration.
Setting not required (setting value will be ignored).
Set the movement amount. (Assuming "mm" is set in "
setting".)
Setting not required (setting value will be ignored).
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.
