Set this option when the machine belongs to rotational system and reversing is not desired.
In this mode, the motor always runs in the set homing direction, and the edge of home sensor is detected and
set to the home. (In this case, runs in + direction only with no reversing.)
If a limit sensor in running direction is detected during homing, homing error (E-HO) is found.

e.g. : When "Pr41 Detects the homing direction in
−

In using this mode, the motor at the home position is within the limit sensor, therefore be sure to set the home
offset (Pr47). When the offset is set to -100, the point which is moved 100 pulses in + direction as viewed from
the edge of limit sensor in - direction is set to the home. (Set a value of plus and minus opposite to the desired
travel direction as an offset.)
