Use example of clutch
The following machine shows an example using clutch control for a flying shear cutting system that synchronizes off a start
signal from a sensor input.

[Pr.406] Main shaft clutch reference address setting 0: Position value after composite main shaft gear
[Pr.408] Movement amount before main shaft clutch ON 0mm
[Pr.410] Movement amount before main shaft clutch OFF 380 mm (14.96inch)
[Pr.411] Main shaft clutch smoothing method 4: Slippage method (Linear)
[Pr.413] Slippage amount at main shaft clutch ON 100mm (3.94inch) (Distance between the sensor and the waiting position)
[Pr.414] Slippage amount at main shaft clutch OFF 20mm (0.79inch)
