CONTROL
[Function]
The spindle synchronous control mode is entered by turning this signal ON.
[Operation]
The spindle synchronous control mode is entered by inputting the "Spindle synchronous control"
signal (SPSY). During the spindle synchronous control mode, the synchronous spindle is controlled
in synchronization with the rotation speed commanded for the basic spindle.
Set the basic spindle, synchronous spindle and rotation direction beforehand.
