During an axis stop with the M12 command the actual posiĆ
tion will be accepted as the new nominal position.
Warning
If an interfering variable causes a deviation between the
actual and nominal positions, the constant repetition of
the axis stop command (M12) can cause the drive to drift.
Each time the M12 command is accessed, the new actual
position will be accepted again as the new nominal posiĆ
tion.
Avoid the drifting by programming a locking which will
prevent the constant repetition of the axis stop command
(M12).
