Automatic Operation (Synchronous Control)

12.3.2 Precautions When Canceling or Starting Synchronous Control

 Precautions when canceling synchronous control
• The synchronous control can be canceled during the master operation, however, slave axes
will stop immediately.
• It is recommended to cancel the synchronous control after stopping slave axes using the
clutch function.
• When the synchronous control is canceled, relays related to the synchronous control
(synchronous slave gear ratio change state annunciation, synchronous slave clutch
connection state notification) will turn off.
 Conditions for starting synchronous control
Only when the following conditions are met, the synchronous control can be started.
• Slave axes stop.
• No stop request for slave axes is generated.
• No error occurs in slave axes.
When these conditions are not met, the unit does not become the synchronous state and the
synchronous control cancel active annunciation relay does not turn off. If the synchronous
cancel request kept off while the conditions are not met, the synchronous control will start
once the condition to start the synchronous control is met.
 Phase when starting synchronous control
It is calculated from the "current value after unit conversion" of master axis and the "cam
control synchronous master axis cycle" of synchronous parameter. The remainder obtained by
dividing "current value after unit conversion" by "cam control synchronous master axis cycle"
is used as a phase.
