If the negative edge of the home switch is selected in the homing configuration command a
similar motion path would be followed, but finishing on the other side of the home switch, as
shown in Figure 4-9.

Motion starting on the negative side of the home switch will behave in a similar way, the only
difference being the direction of travel. If the drive was started up already within the
boundaries of the home switch and a go home command was given for a particular edge the
motion would follow the path shown in Figure 4-10, depending upon which edge was
requested. In this situation the home position is known so the indexer knows in which
direction to travel to seek the appropriate edge. In Figure 4-10 acceleration and deceleration
are set to the same value.
