■When positioning in the opposite direction in the middle of operation
The following shows an example of behavior for the following setting values.
In this example, point table number 1 is the absolute position command method, point table number 2 is the relative position
command method, and point table number 3 is the absolute position command method.

*2 Always set "0" or "2" for the auxiliary function of the last point table among consecutive point tables.

For the operation timing of S_INP (in-position), S_CPO (rough match), S_MEND (traveling completion), [Point actual value
(Obj. 2D69h)], [Point demand value (Obj. 2D68h)] and [M code actual value (Obj. 2D6Ah)], refer to "When positioning to the
same direction".

Repetitive positioning operation (absolute value command method)
Set the auxiliary function of the point table to return to the operation pattern of the set point table number and enable the
repetitive positioning operation.
When "8" or "10" is set for the auxiliary function, continuous operation or speed change operation is performed up to the point
table, and after positioning is completed, continuous operation or speed change operation is performed again from the
operation pattern of the point table number at startup.
When "9" or "11" is set for the auxiliary function, continuous operation or speed change operation is performed up to the point
table, and after positioning is completed, continuous operation or speed change operation is performed again from the
operation pattern of the point table number 1.
