6.3.4 Behaviour of the Lenze EtherCAT nodes during start−up
If the DC synchronisation is used, the communication module first changes to the
"Operational" state if the standard device has adapted its phase position to the DC signal.
This process can take several seconds.
)
Note!
ƒ If the communication module does not change to "Operational", there
possibly is an error in the configuration or the EtherCAT wiring.
ƒ The communication module compares the cycle time specified by the
EtherCAT master to the cycle time of the standard device set in C1121. The
synchronisation cycle time in the master has to be equal to the cycle time of
the standard device.
ƒ Moreover it is checked whether the selection of the sync source in the
standard device code C01120 is correct.
ƒ Further information can be gathered from the master as status information
or an emergency message.
