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.

Setting item Setting details
[Cd.406] • Set "1" to initiate a synchronous control
Synchronous change command request. The value is reset
control change to "0" automatically after completion of the
request synchronous control change.
Fetch cycle: Operation cycle
[Cd.407] • Set the synchronous control change
Synchronous command.
control change Fetch cycle: At request (Synchronous control
command change request)
[Cd.408] • Set the change value for synchronous control
Synchronous change processing.
control change Fetch cycle: At request (Synchronous control
value change request)
[Cd.409] • Set the reflection time for synchronous
Synchronous control change processing.
control reflection Fetch cycle: At request (Synchronous control
time change request)
*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.

Application
Adjust the cam reference position by the
movement amount.
Change the cam axis position value per cycle.
Change the position value per cycle after main
shaft gear.
Change the position value per cycle after auxiliary
shaft gear.
Adjust the phase of the cam axis by the movement
amount.
