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.
Sensor input
(High speed input
request signal)
100mm(3.94inch)
Synchronous
encoder
Waiting position
Sensor position
Main shaft clutch setting item
[Pr.405] Main shaft clutch control setting
(D15008+150n)
[Pr.406] Main shaft clutch reference address setting (D15009+150n)
[Pr.408] Travel value before main shaft clutch ON (D15012+150n, D15013+150n)
[Pr.410] Travel value before main shaft clutch OFF (D15016+150n, D15017+150n)
[Pr.411] Main shaft clutch smoothing method (D15018+150n)
[Pr.413] Slippage amount at main shaft clutch ON (D15020+150n, D15021+150n)
[Pr.414] Slippage amount at main shaft clutch OFF (D15022+150n, D15023+150n)

Setting value
5: High speed input request
1: One-shot OFF
(Specify the high speed input request signal No., used for sensor input.)
0: Current value after composite main shaft gear

380[mm] (14.96[inch])
4: Slippage method (Linear)
100[mm] (3.94[inch])
(Distance between the sensor and the waiting position)
20[mm] (0.79[inch])
t
All travel value of output axis
...380mm+(20mm-100mm)=300mm
(14.96inch+(0.79inch-3.94inch)=11.81inch)
t
Complete synchronous control and
return to the waiting position by
positioning control.
(It can be returned by auxiliary shaft
without changing synchronous control.)
