(b) Automatic continuous positioning operation
By merely selecting a point table and switching on "Controlword bit 4 (New set-point)", the operation
can be performed in accordance with the point tables having consecutive numbers.
1) Absolute value command method ([Pr. PT01] = _ _ _ 0)
By specifying the absolute value command or the incremental value command in the auxiliary
function of the point table, the automatic continuous operation can be performed.
The following shows how to set.

a) Positioning in a single direction
The following shows an operation example with the set values listed in the table below.
In this example, point table No. 1 and No. 3 are set to the absolute value command method,
and point table No. 2 to the incremental value command method.
