[Pr.422] Auxiliary shaft clutch control setting
Set the ON and OFF control methods separately for the auxiliary shaft.
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.403] Auxiliary shaft clutch command" ON/OFF. (Setting in the
OFF control mode are not applicable in this mode.)
The clutch is turned ON when "[Cd.403] Auxiliary shaft clutch command" passes the leading edge (from OFF to ON).
The clutch is turned ON when "[Cd.403] Auxiliary shaft clutch command" passes the trailing edge (from ON to OFF).
The clutch is turned ON when the reference address (the auxiliary shaft current value or the position value per cycle
after auxiliary shaft gear) reaches "[Pr.424] Auxiliary 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.
