116 Naming & Configuring Your Motion Axis
Sequence
Select the event that causes the Home Position to be set:
Note: See the section “Homing Configurations,” below, for a detailed
description of each combination of homing mode, sequence and
direction.
Limit Switch
If a limit switch is used, indicate the normal state of that switch (i.e., before
being engaged by the axis during the homing sequence):
• Normally Open
• Normally Closed
Direction
For active homing sequences, except for the Immediate Sequence type, select
the desired homing direction:
Sequence Type: Description:
Immediate Sets the Home Position to the present actual position,
without motion.
Switch Sets the Home Position when axis motion encounters a
home limit switch.
Marker Sets the Home Position when axis encounters an encoder
marker.
Switch-Marker Sets the Home Position when axis first encounters a
home limit switch, then encounters an encoder marker.
Direction Description
Forward Uni-directional The axis jogs in the positive axial direction until a homing
event (switch or marker) is encountered, then continues in
the same direction until axis motion stops (after
decelerating or moving the Offset distance).
Forward Bi-directional The axis jogs in the positive axial direction until a homing
event (switch or marker) is encountered, then reverses
direction until motion stops (after decelerating or moving
the Offset distance).
Reverse Uni-directional The axis jogs in the negative axial direction until a
homing event (switch or marker) is encountered, then
continues in the same direction until axis motion stops
(after decelerating or moving the Offset distance).
Reverse Bi-directional The axis jogs in the negative axial direction until a
homing event (switch or marker) is encountered, then
reverses direction until motion stops (after decelerating
or moving the Offset distance).
