(2) 1-axis linear control (INC linear 1)
Operation chart
In increment system 1-axis linear control, addresses established by a machine
zero point return 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
" Da.5 Positioning address/movement amount". The movement direction is
determined by the sign of the movement amount.
Example
When the start point address is 5000, and the movement amount is -7000, positioning is carried out to
the -2000 position.
-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.
Setting example
Positioning Set "Positioning complete" assuming the next positioning data will not
complete be executed.
INC linear 1 Set increment system 1-axis linear control.
Designate the value set in " Pr.26 Acceleration time 1" as the
1
acceleration time at start.
Designate the value set in " Pr.9 Deceleration time 0" as the
0
deceleration time at deceleration.
Set the movement amount. (Assuming "mm" is set in " Pr.1 Unit
– 7 0 0 0 . 0  m
setting".)
– Setting not required (setting value will be ignored).
6000.00mm/min Set the speed during movement.
Set the time the machine dwells after the positioning stop (pulse output
500ms
stop) to the output of the positioning complete signal.
Set this when other auxiliary operation commands are issued in
10
combination with the No. 1 positioning data.
