4. HOW TO USE THE POINT TABLE
4 - 20
(b) Automatic continuous positioning operation
By merely selecting a point table and switching on ST1 (Forward rotation start) or ST2 (Reverse
rotation start), 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.

When the position data is absolute value When the position data is incremental value
1 or more 1 3
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 the incremental value command method.

Note 1. For MR-JE-_A servo amplifiers, up to four points of DO are available; therefore, PT0 to PT4 cannot be outputted
simultaneously.
