CONTROL
[Function]
This signal informs that the spindle synchronous control mode has been entered.
[Operation]
The signal turns ON when:
• The G114.1 is commanded, and spindle synchronous control is entered. (Spindle synchronous
control I)
• The spindle synchronous control signal (Y432) turns ON. (Spindle synchronous control II)
The signal turns OFF when:
• Spindle synchronous control is canceled with the G113 command. Or, when the spindle
synchronization cancel signal (Y430) turns ON. (Spindle synchronous control I)
• When the spindle synchronous control signal (Y432) turns OFF. (Spindle synchronous control II)

SPINDLE ROTATION SPEED
— SYNCHRONIZATION
COMPLETE
[Function]
This signal informs that the spindle synchronization state mode is entered.
[Operation]
The signal turns ON when:
• The difference of the rotation speeds of the basic spindle and synchronous spindle reaches the
value set for the spindle rotation speed attainment level during the spindle synchronous control
mode.
The signal turns OFF when:
• The actual rotation speed of the synchronous basic spindle or synchronous spindle, in respect to
the spindle synchronous rotation speed command value, widely exceeds or deviates value set for
the spindle synchronization rotation speed attainment level during the rotation synchronization
mode.
• The spindle synchronous control mode is canceled.
