(1) Start of the axis (2) Twin head reach the nominal position earlier, Overshot
control needs 11ms longer to trigger the end signal
(3) Overshot is higher than ’allowed deviation of position’ at the Twin head--> end signal delayed

(1) Start of the axis (2) Twin head reach the nominal position nearly at the
same time, but Overshot control need 7ms longer to
trigger the end signal
(3) Overshot is higher than ’allowed deviation of
