SyncUnit diagnostics

The individual servo drives should be consolidated in meaningful groups, depending on the application. Each of these groups is allocated to a SyncUnit. Since each group has its own working counter, the individual groups can continue to operate independently in the event of fatal errors. For particularly critical applications, each AX5000 can be allocated a separate Sync Unit. However, this step should only be implemented in cases where it is actually required, because each further Sync Unit results in additional data traffic on the EtherCAT strand.
