In "1-axis linear control" (" Da. 2 Control method" = 1-axis linear control (ABS), 1-axis
linear control (INC), 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
control are used. Position control 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".
Example
When the start point address (current stop position) is 1000, and the end point address (positioning address) is 8000,
position control is carried out in the positive direction for a movement amount of 7000 (8000-1000)
0 1000
Positioning control (movement amount 7000)
Positioning data setting example
The following table shows setting examples when "1-axis linear control (ABS)" is set
in positioning data No. 1 of axis 1.
Setting example
Positioning Set "Positioning termination" assuming the next positioning data will not
termination be executed.
