[Pr.409] Main shaft clutch OFF address
Set the clutch OFF address when address mode is configured for the OFF control mode of the main shaft clutch.
When the reference address is the current value per cycle after main 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 OFF address is controlled as 60 pulses when the setting value is "40060".
[Pr.410] Movement amount before main shaft clutch OFF
Set the movement amount of the reference address with a signed value between the clutch OFF condition completing and the
clutch opening.
Setting value
1 to 2147483647 (Positive value)
0
-2147483648 to -1 (Negative value)
Clutch OFF condition is completed
(Example: [Cd.400] Main shaft

5: Slippage method (Linear: Input
value follow up)
[Pr.412] Main shaft clutch smoothing time constant
Set a time constant when the time constant method is set in "[Pr.411] Main shaft clutch smoothing method".
The time constant setting applies for clutch ON/OFF.
[Pr.413] Slippage amount at main shaft clutch ON
Set the slippage amount at clutch ON when the slippage method is set in "[Pr.411] Main shaft clutch smoothing method".
The slippage amount is set in units based on the current value selected in "[Pr.406] Main shaft clutch reference address
setting".
If the set amount is negative, slippage amount at clutch ON is controlled as 0 (direct).
Details
Used when the reference address is increasing in direction.
No movement amount (The clutch is immediately turned OFF with the clutch OFF condition completing.)
Used when the reference address is decreasing in direction.
