D When this signal is set to 1, the spindle is oriented by shortcut rotation,
regardless of the specification of the rotation direction command for
spindle orientation stop position modification (ROTAA).
(f) Rotation direction command for spindle orientation stop position modification (ROTAA)
D This signal is used to specify a rotation direction when the spindle is
oriented to a different position immediately after spindle orientation.
When this signal is set to 0, the spindle rotates counterclockwise and
stops.
When this signal is set to 1, the spindle rotates clockwise and stops.
D This signal is valid when the shortcut rotation command for spindle
orientation stop position modification (NRROA) is set to 0.
(g) Spindle orientation external–type stop position command (SHA11 to SHA00)
D This signal is used to specify a stop position when the orientation
function of external stop position setting type is used. A stop position
is determined using the formula below. This command specifies an
absolute position within one rotation.

Note that Pi = 0 when SHAi =0, and Pi = 1 when SHAi = 1.
D When a spindle orientation function of external stop position setting
type is used, the parameter (parameter No. 4031 (FS16)) for setting a
stop position in spindle orientation of position coder type is disabled.
