6 POSITIONING CONTROL
[Cautions]
[Program]
(1) Number of control axes is 1 axis.
(2) Only the absolute data method (ABS ) is used for positioning control to the pass
points.
(3) The speed can be changed during the start.
The changed speed is effective until the stop command is input.
(4) Set the positioning address in the servo program using indirect setting with the
word devices.
(5) Use only even-numbered devices for indirect setting of positioning address in the
servo program.
If odd-numbered devices are used, a minor error (error code: 141) occurs at the
start and control does not start.
(6) Positioning speeds can be set in the servo program using indirect setting with the
word devices.
However, this data is effective only at the position follow-up control start (servo
program start) and the speed does not change if the indirect setting are changed
during the start.
