Synchronous Control Change Function

Overview of synchronous control change function

This function can be used to change the cam reference position, the cam axis current value per cycle and the current value
per cycle after the main/auxiliary shaft gear during the synchronous control.
The following 5 methods exist for the synchronous control change function. (Page 133 [Cd.407] Synchronous control

Synchronous control change command
Cam reference position movement
Change cam axis current value per cycle
Change current value per cycle after main shaft gear
Change current value per cycle after auxiliary shaft gear

Set ON to initiate "[Cd.407] Synchronous control change command (R: D42770+160n/Q: D15130+150n)". The "[St.426]
Control change complete (R: M38966+16n/Q: M10566+10n)" turns ON at the after completion of the synchronous control
change. "[Rq.406] Control change request command (R: M42408+16n/Q: M11688+10n)" turns OFF at the synchronous
control start.

■[St.426] Control change complete (R: M38966+16n/Q: M10566+10n)
This signal turns ON with the completion of control change.
If the control change processing is stopped midway, the signal remains to be OFF.
