4. HOW TO USE THE POINT TABLE
(b) Parameter setting
Set the following parameters to perform automatic operation.
1) Command method selection ([Pr. PT01])
Select the incremental value command method as shown below.
2) Rotation direction selection ([Pr. PA14])
Select the servo motor rotation direction when ST1 (Forward rotation start) or ST2 (Reverse
rotation start) is switched on.
3) Position data unit ([Pr. PT01])
Set the unit of the position data.
4) Feed length multiplication ([Pr. PT03])
Set the feed length multiplication (STM) of the position data.
[Pr. PT03] setting
_ _ _ 0
_ _ _ 1

_ _ _ 3
Note. The feed length multiplication setting ([Pr. PT03]) is not applied to the unit multiplication factor.
Adjust the unit multiplication factor in the electronic gear setting ([Pr. PA06] and [Pr. PA07]).
