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 [DI])
100 mm
(3.94 inch)
Synchronous
encoder
Waiting position
Sensor position
Main shaft clutch setting item
[Pr.405]
Main shaft clutch control setting
[Pr.406] Main shaft clutch reference address setting
[Pr.408] Movement amount before main shaft clutch ON
[Pr.410] Movement amount before main shaft clutch OFF
[Pr.411] Main shaft clutch smoothing method
[Pr.413] Slippage amount at main shaft clutch ON
[Pr.414] Slippage amount at main shaft clutch OFF
High speed input request [DI]
Clutch smoothing status
Clutch ON/OFF status
Synchronous encoder axis speed
Output axis speed
Slippage amount at clutch ON
...Distance between the sensor and
the waiting position (100 mm(3.94 inch))
M
Output axis
ON control mode
OFF control mode
High speed input signal
Synchronous encoder axis and
output axis in synchronization
Cutting...After clutch smoothing
All movement amount of output axis
...380 mm + (20 mm - 100 mm) = 300 mm
(14.96 inch + (0.79 inch - 3.94 inch) = 11.81 inch)
Slippage amount at clutch OFF
...Set as 20 mm (0.79 inch)
to stop early.

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

Complete synchronous control and return
to the waiting position by positioning control.
(It can be returned by auxiliary shaft without
changing synchronous control.)
