7. HOW TO USE THE POINT TABLE
(d) Automatic repeat positioning operation
By setting the auxiliary function of the point table, the operation pattern of the set point table No. can
be returned to, and the positioning operation can be performed repeatedly.
1) Absolute value command method ([Pr. PT01] = _ _ _ 0)
Setting "8" or "10" to the auxiliary function performs an automatic continuous operation or a
varying-speed operation until that point table, and after the completion of positioning, performs
the operation again from the operation pattern of the point table No. used at start-up.
Setting "9" or "11" to the auxiliary function performs an automatic continuous operation or a
varying-speed operation until that point table, and after the completion of positioning, performs
the operation again from the operation pattern of point table No. 1.
a) Automatic repeat positioning operation by absolute value command method
Example 1. Operations when "8" is set to the auxiliary function of point table No. 4

Operation sequence
1) Starting with point table No. 2
2) Executing point table No. 3
3) Executing point table No. 4
4) Executing again point table No. 2 used at start-up when "8" is set to the auxiliary function of
point table No. 4
5) Repeating the above execution in the sequence of 2), 3), 4), 2), 3), 4)
