The basic conditions mentioned above cause the following processing times for the process data in
the inverter:
• DC use (synchronised operation):
The processing time starts with the acceptance of the setpoints by the inverter with the Sync0
event (DC synchronisation cycle) and ends with the provision of the current actual values in the
EtherCAT interface.
Depending on the selected Process data mode
( 40) (C13892 / C14892), the resulting
processing times are as follows:
• Deterministic mode: 2.1 ms + interval time of the application task
• Optimised mode: 1.3 ms + interval time of the application task
• No DC use (non-synchronised operation):
The processing time starts with the acceptance of the setpoints by the inverter at a time that is
not synchronised with the EtherCAT master and ends with the provision of the current actual
values in the EtherCAT interface.
Hence, the following holds true for the processing time:
1.3 ms + 1.0 ms (tolerance) + interval time of the application task

Here you can find detailed information on how to set the interval time of the application
task.
