[Pr.422] Auxiliary shaft clutch control setting (D15030+150n)
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 to "No clutch" (Direct coupled
operation) cannot be selected during synchronous control after already selecting another setting.
Refer to control method for clutch for details on the clutch control. (Page 99 Control method for clutch)

Setting details
• Set the travel value for the
distance between the clutch
OFF condition completing
and the clutch opening.
• Set a positive value when the
reference address is
increasing, and a negative
value when it is decreasing.
Set the clutch smoothing
method.
For smoothing with a time
constant method, set the
smoothing time constant.
For smoothing with a slippage
method, set the slippage
amount at clutch ON.
For smoothing with a slippage
method, set the slippage
amount at clutch OFF.
Description
Execute direct coupled operation without clutch control.
The clutch is turned ON/OFF by the operation of "[Rq.403] Auxiliary shaft clutch command (M11684+10n)" ON/
OFF. (Setting in the OFF control mode are not applicable in the clutch command ON/OFF mode.)
The clutch is turned ON when "[Rq.403] Auxiliary shaft clutch command (M11684+10n)" passes the leading edge
(from OFF to ON).
The clutch is turned ON when "[Rq.403] Auxiliary shaft clutch command (M11684+10n)" passes the trailing edge
(from ON to OFF).
The clutch is turned ON when the reference address (the auxiliary shaft current value or the current value per
cycle after auxiliary shaft gear) reaches "[Pr.424] Auxiliary shaft clutch ON address (D15032+150n,
D15033+150n)".
The travel value after passing through the ON address is calculated as the output travel value of the clutch based
on the reference address passing through, thereby controlling the clutch with an accurate travel value.
The clutch is turned ON when the high speed input request signal turns ON.
