・SV speed control mode cancellation
If you perform live tool indexing with G96.1, SV speed control mode is
canceled when live tool indexing is completed.
If you perform live tool indexing with G96.2, use G96.3 to check for the
completion of live tool indexing; it cancels SV speed control mode if it is
completed. The G96.2 command alone does not cancel SV speed control
mode.
・Live tool indexing command during spindle rotation
During spindle rotation, specifying G96.1/G96.2 and a position allows you
to stop the rotation of the spindle at the specified position.
Example) M03 S1000 ; … Rotation at S1000
G96.1 P1 R180. ; … Stoppage of rotation at the 180° position
・Live tool indexing speed
If the speed is specified with G96.1/G96.2, the movement speed is for live
tool indexing only. Set the live tool indexing speed in parameter
No. 11012.
Live tool indexing acceleration/deceleration
