6.4.3 Response of the Lenze EtherCAT nodes during start-up
Code C13883 / C14883 shows whether the DC synchronisation has been activated for the
communication module.
If the DC synchronisation is used, the communication module only changes to the "Operational"
state when the standard device has adapted its phase position to the DC signal. This process may
take several seconds.
The cycle time (in μs) set by the master on the fieldbus is displayed with code C13870 / C14870 .
The state of the standard device synchronicity is displayed in code C13884 / C14884 .

Note!
• If the communication module does not change to the "Operational" state, there might
be an error in the configuration or in the EtherCAT wiring.
• The communication module compares the cycle time defined by the EtherCAT master
to the internal processing time (1 ms) of the standard device. The synchronisation
cycle time in the master must be identical with or an integer multiple of 1 ms.
• Furthermore it is checked whether the sync source selection in standard device code
C01120 is correct.
• Further information can be found in the status information or emergency messages
of the master.
