10. Spindle Functions
Starting spindle synchronization
The spindle synchronous control mode is entered by inputting the spindle synchronous control
signal (SPSYC). The synchronous spindle will be controlled in synchronization with the rotation
speed commanded for the basic spindle during the spindle synchronous control mode.
When the difference of the basic spindle and synchronous spindle rotation speeds reaches the
spindle synchronization rotation speed reach level setting value (#3050 sprlv), the spindle rotation
speed synchronization complete signal (FSPRV) will be output.
The synchronous spindle's rotation direction is designated with the spindle synchronization
rotation direction designation as the same as the basic spindle or the reverse direction.

10.8 Spindle synchronization control II
Explanation
The spindle synchronous control mode is
entered when this signal turns ON.
This notifies that the mode is the spindle
synchronous control.
This turns ON when the difference of the basic
spindle and synchronous spindle rotation
speeds reaches the spindle rotation speed
reach level setting value during the spindle
synchronous control mode.
This signal turns OFF when the spindle
synchronous control mode is canceled, or
when an error exceeding the spindle rotation
speed reach level setting value occurs during
the spindle synchronous control mode.
Designate the basic spindle and synchronous
spindle rotation directions for spindle
synchronous control.
0: The synchronous spindle rotates in the
same direction as the basic spindle.
1: The synchronous spindle rotates in the
reverse direction of the basic spindle.
