(6) Homing profile without using OT
Below is an example of the setting for returning to the home position with the home position LS
signal without the OT signal. Use this profile for mechanical configurations where one of directions
of the moving part of the mechanical system is turned on with the home position LS signal as
shown in the figure below. The starting direction for homing is automatically determined according
to the setting of PA2_10 (homing direction after reference signal detection) and the ON/OFF state
of the home position LS at which return begins.

PA2_13: Home position LS signal edge selection indicates selection of the edge of the home
position LS corresponding to the direction of homing.
If PA2_08 is set at “2,” use of the home position LS is assumed. Accordingly the following
conditions are included in combination conditions.
PA2_11 (Reference signal for shift operation) = 0 (home position LS) or
PA2_11 (Reference signal for shift operation) = 1 (encoder Z-phase) and PA2_12 (reference signal for
homing) = 0 (home position LS)
