[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.
Page 108 Control method for clutch
■ON control mode
Other clutch parameters are not applicable during direct coupled operation by setting "0: No clutch". "[Cd.405]
Auxiliary shaft clutch forced OFF command" and the change of the clutch control setting are ignored during
direct coupled operation.

Setting value Details
0: No clutch (Direct coupled
operation)
Execute direct coupled operation without clutch control.
1: Clutch command ON/OFF 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.)
2: Clutch command leading edge The clutch is turned ON when "[Cd.403] Auxiliary shaft clutch command" passes the leading edge (from OFF to ON).
3: Clutch command trailing edge The clutch is turned ON when "[Cd.403] Auxiliary shaft clutch command" passes the trailing edge (from ON to OFF).
4: Address mode 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.
5: High speed input request The clutch is turned ON when the high speed input request [DI] turns ON.
