Meaning
Defines the distance from the destination at
which the drive is slowed down from creep feed
to 0. If the switch-off difference ≥ the switchover
difference, there is no switchover point. There is
no slowdown from rapid feed to creep feed.
Defines the distance from the destination at
which the drive is slowed down from rapid feed
to creep feed.
