(3) Stop position external setting type spindle orientation
NOTE
Set t = 50 msec or more.
Stop <1>
• Predetermined stop position based on the normal orientation
command
• The rotation direction of the spindle motor is determined by
parameter setting.
• After the power is turned on, the spindle rotates at the orientation
speed and seizes the one-rotation signal before stopping at a
predetermined position for the first time. After the first stop, the
spindle stops at a predetermined position within one rotation.
• When the stop position external setting type spindle orientation
function is used, the spindle stops at a predetermined position
after shifting by the stop position data read on the rising edge of
the spindle orientation command signal if the data of the spindle
orientation stop position command SHA00-SHA11 is set after
the first stop.
