10. Spindle Functions
Rotation and rotation direction
(1) The rotation speed and rotation direction of the basic spindle and synchronous spindle during
spindle synchronous control are the rotation speed and rotation direction commanded for the
basic spindle. Note that the rotation direction of the synchronous spindle can be reversed from
the basic spindle through the program.
(2) The basic spindle's rotation speed and rotation direction can be changed during spindle
synchronous control.
(3) The synchronous spindle's rotation command is also valid during spindle synchronous control.
When spindle synchronous control is commanded, if neither a forward run command nor
reverse run command is commanded for the synchronous spindle, the synchronization
standby state will be entered without starting the synchronous spindle's rotation. If the forward
run command or reverse run command is input in this state, the synchronous spindle will start
rotation. The synchronous spindle's rotation direction will follow the direction commanded in
the program.
If spindle stop is commanded for the synchronous spindle during spindle synchronization
control (when both the forward run and reverse run commands are turned OFF), the
synchronous spindle rotation will stop.
(4) The rotation speed command (S command) and constant surface speed control are invalid for
the synchronous spindle during spindle synchronous control. Note that the modal is updated,
so these will be validated when the spindle synchronization is canceled.
(5) The constant surface speed can be controlled by issuing a command to the basic spindle even
during spindle synchronous control.
