4.6 Synchronous Control Change Function
4.6 Synchronous Control Change Function
Overview of synchronous control change function
This function can change the cam reference position, the cam axis position value per cycle and the position value per cycle
after the main/auxiliary shaft gear during the synchronous control.
The following 5 methods exist for the synchronous control change function. Refer to the following on each change command.

n: Axis No. - 1
*1 Set the value as follows in a program.
0 to 32767: Set as a decimal.
32768 to 65535: Convert into a hexadecimal and set.
[Cd.406] Synchronous control change request
Set "1" to execute "[Cd.407] Synchronous control change command". After completion of synchronous control change, "0" is
automatically stored by the Motion module.
The setting is initialized to "0" when starting synchronous control.
