Festo P.BE−SPC200−EN en 0901d
During an axis stop with the M12 command the actual posi
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 posi
tion.
Avoid the drifting by
programming a locking which will
prevent the constant repetition of the axis stop command
(M12).
