[Pr.405] Main shaft clutch control setting
Set the ON and OFF control methods separately for the main shaft clutch.
The clutch control setting can be changed during synchronous control, however, the setting "No clutch" (Direct coupled
operation) cannot be selected during synchronous control after already selecting another setting.
Refer to the following for operation details on the clutch control.

Details
Execute direct coupled operation without clutch control.
The clutch is turned ON/OFF by the operation of "[Cd.400] Main shaft clutch command" ON/OFF. (Setting in the OFF
control mode is not applicable in this mode.)
The clutch is turned ON when "[Cd.400] Main shaft clutch command" passes the leading edge (from OFF to ON).
The clutch is turned ON when "[Cd.400] Main shaft clutch command" passes the trailing edge (from ON to OFF).
The clutch is turned ON when the reference address (the position value after composite main shaft gear or the position
value per cycle after main shaft gear) matches "[Pr.407] Main shaft clutch ON address".
The movement amount after passing through the ON address is calculated as the output movement amount of the clutch
based on the reference address passing through, thereby controlling the clutch with an accurate movement amount.
The clutch is turned ON when the high speed input request [DI] turns ON.
Details
Clutch OFF control is not used. This setting is applicable only for execution with clutch ON control.
The clutch is turned OFF after moving the distance "[Pr.410] Movement amount before main shaft clutch OFF" (One-
shot operation) after "[Md.420] Main shaft clutch ON/OFF status" turns ON.
If "[Pr.410] Movement amount before main shaft clutch OFF" is 0, "[Md.420] Main shaft clutch ON/OFF status" does not
turn ON in order to turn back OFF immediately.
The clutch is turned OFF when "[Cd.400] Main shaft clutch command" passes the leading edge (from OFF to ON).
The clutch is turned OFF when "[Cd.400] Main shaft clutch command" passes the trailing edge (from ON to OFF).
The clutch is turned OFF when the reference address (the position value after composite main shaft gear or the position
value per cycle after main shaft gear) reaches "[Pr.409] Main shaft clutch OFF address".
The movement amount before passing through the OFF address is calculated as the output movement amount of the
clutch based on the reference address passing through, thereby controlling the clutch with an accurate movement
amount.
The clutch is turned OFF when the high speed input request [DI] turns ON.
