The mentioned basic conditions result in the following processing times for the process data in the
drive:
• DC use (synchronised operation):
The processing time starts with the acceptance of the setpoints by the drive 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 ( 39) ( C13892 / C14892 ), the following
processing times result:
• 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 drive 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.
The following processing time arises:
1.3 ms + 1.0 ms (tolerance) + interval time of the application task

task.
