16. HOW TO USE THE POINT TABLE
(2) Parameter setting
Set the following parameters to perform automatic operation.
(a) Rotation direction selection ([Pr. PA14])
Select the servo motor rotation direction when "Controlword bit 4 (New set-point)" is switched on.
[Pr. PA14] setting

"Controlword bit 4 (New set-point)" on
0
CCW rotation with + position data
CW rotation with - position data

CW rotation with + position data
CCW rotation with - position data
(b) Position data unit ([Pr. PT01])
Set the unit of the position data.
[Pr. PT01] setting

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]).
(3) Operation
Selecting the point table with "Target point table" and switching on "Controlword bit 4 (New set-point)"
starts positioning to the position data at the set speed, acceleration time constant and deceleration time
constant.
