[Pr.406] Main 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 main
shaft gear and the main shaft clutch will change depending on the reference address setting.
Setting value
0: Position value after composite
main shaft gear
1: Position value per cycle after
main shaft gear
The setting values for the following parameters are in units based on the reference address setting.
• "[Pr.407] Main shaft clutch ON address"
• "[Pr.409] Main shaft clutch OFF address"
• "[Pr.408] Movement amount before main shaft clutch ON", "[Pr.410] Movement amount before main shaft clutch OFF"
• "[Pr.413] Slippage amount at main shaft clutch ON", "[Pr.414] Slippage amount at main shaft clutch OFF"
[Pr.407] Main shaft clutch ON address
Set the clutch ON address when address mode is configured for the ON control mode of the main shaft clutch.
When the reference address is the position 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 ON address is controlled as 19000 pulses when the setting value is "-1000".
[Pr.408] Movement amount before main shaft clutch ON
Set the movement amount of the reference address with a signed value between the clutch ON condition completing and the
clutch closing.
Setting value
1 to 2147483647 (Positive value)

[Md.401] Position value per cycle
after main shaft gear
Movement amount after clutch output
[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 position 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".
Details
The clutch is controlled by using the position value after composite main shaft gear as a reference.
Output after the clutch is a converted movement amount through the main shaft gear.
The clutch is controlled by using the position value per cycle after main shaft gear.
Output after the clutch is a movement amount without conversion.
Details
Used when the reference address is increasing in direction.
No movement amount (The clutch is immediately turned ON with the clutch ON condition completing.)
