Format  default value: 
Setting  , Tool returns to machine origin along positive direction of coordinate.
Setting  1, Tool returns to machine origin along negative direction of coordinate.
Set this parameter to adust the homing direction if the user finds the homing
direction is not correct.

Taking -ais for eample:
Setting : Means when -ais Motor returns to machines ome Position
OM, the direction for Section-2 to leave imit Switch and
for Section-3 to find ero point RI will be opposite to
Section 1; whereas, the direction for Section-2 to leave imit
Switch and for Section-1 to find ero point RI will be the
same, as per Fig. 4-11 
Setting 1: Means when -ais Motor returns to machines ome Position
OM, the direction for Section-2 to leave the imit Switch
will be consistent with that for Section-1; whereas, the direction
for Section-3 to find ero-point RI will be opposite to that
for Section-1 and Section-2, as per Fig. 4-11 C.
