For spindle control, the following normal miscellaneous functions are
used:
See the description of the miscellaneous functions.
M03: CW spindle rotation
M04: CCW spindle rotation
M05: Spindle stop
M19: Spindle orientation (M series)
When the rotation direction of the spindle is to be switched from one
direction to the other (for example, when M04 is output during M03
operation), a parameter can specify whether to send M05 at the time
switching.
