7.3.6 Management to Resume Slave CPU Synchronization
The slave CPU synchronous process is automatically carried out when its execution requirements are met.
Here, in a transient state from slave CPU asynchronous to slave CPU synchronous state, the following operations are
carried out by the system:
• Start of timing adjustment of the slave scan cycle
• When SVB-01 is attached to a optional slave slot, the MECHATROLINK communication is reset
As a result operation of the slave side application is affected as follows:
• One scan with a longer cycle than the setup time occurs
• When a servo connected to the SVB-01 is running, its axis stops and an alarm occurs
To avoid these impacts (to avoid automatic recovery to the slave CPU synchronous state), use the slave side application
to operate a control bit “SLVSC (slave CPU synchronous resume control)”.
Operating this bit allows you to control the synchronous process.

Resume enable
When out of slave CPU synchronization, the slave CPU synchroniza-
tion is automatically resumed.

Resume disable
Even when out of slave CPU synchronization, the operation continues
in an asynchronous state.
