■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.
*1 Set to "0".
*2 Always set "0" or "2" for the auxiliary function of the last point table among consecutive point tables.
0: When using the point table as the absolute position command method
2: When using the point table as the relative position command method
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".
Page 554 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.
