4 ADVANCED SYNCHRONOUS CONTROL
4.2 Auxiliary Shaft Module
■OFF control mode
■High speed input request signal
Set the high speed input request signal No. for the ON control mode (1) and the OFF control mode (2) when using the setting
"5: High speed input request".
[Pr.423] Auxiliary shaft clutch reference address setting
Select the address type to be used as the reference address for clutch control. Note that the processing order of the auxiliary
shaft gear and the auxiliary shaft clutch will change depending on the reference address setting.
The setting values for the following parameters are in units based on the reference address setting.
• "[Pr.424] Auxiliary shaft clutch ON address"
• "[Pr.426] Auxiliary shaft clutch OFF address"
• "[Pr.425] Movement amount before auxiliary shaft clutch ON", "[Pr.427] Movement amount before auxiliary shaft clutch
OFF"
• "[Pr.430] Slippage amount at auxiliary shaft clutch ON", "[Pr.431] Slippage amount at auxiliary shaft clutch OFF"
[Pr.424] Auxiliary shaft clutch ON address
Set the clutch ON address when address mode is configured for the ON control mode of the auxiliary shaft clutch.
When the reference address is the position value per cycle after auxiliary shaft gear, the setting address is converted for
control within the range from 0 to (Cam axis length per cycle - 1).
Ex.
Cam axis length per cycle: 20000 pulses
The ON address is controlled as 19000 pulses when the setting value is "-1000".
Setting value Details
0: OFF control invalid Clutch OFF control is not used. This setting is applicable only for execution with clutch ON control.
1: One-shot OFF The clutch is turned OFF after moving the distance "[Pr.427] Movement amount before main shaft clutch OFF" (One-
shot operation) after "[Md.423] Auxiliary shaft clutch ON/OFF status" turns ON.
If "[Pr.427] Movement amount before auxiliary shaft clutch OFF" is 0, "[Md.423] Auxiliary shaft clutch ON/OFF status"
does not turn ON in order to turn back OFF immediately.
2: Clutch command leading edge The clutch is turned OFF when "[Cd.403] Auxiliary shaft clutch command" passes the leading edge (from OFF to ON).
3: Clutch command trailing edge The clutch is turned OFF when "[Cd.403] Auxiliary shaft clutch command" passes the trailing edge (from ON to OFF).
4: Address mode The clutch is turned OFF when the reference address (the auxiliary shaft current value or the position value per cycle
after auxiliary shaft gear) reaches "[Pr.426] Auxiliary 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.
5: High speed input request The clutch is turned OFF when the high speed input request [DI] turns ON.

Setting value Details
0: Auxiliary shaft current value The clutch is controlled by using the position value for the servo input axis/synchronous encoder axis that is set for the
auxiliary shaft.
Output after the clutch is a converted movement amount through the auxiliary shaft gear.
1: Position value per cycle after
auxiliary shaft gear
The clutch is controlled by using the position value per cycle after auxiliary shaft gear.
Output after the clutch is a movement amount without conversion.
