Adjusting the task cycle time and DC cycle time
The Lenze Controller is the EtherCAT master. The clock pulse of the bus system is determined by the
cycle time of the task that is assigned to the drives (slaves) integrated in the »PLC Designer«.
The task settings in »PLC Designer« only support integer millisecond cycles and the smallest
possible bus cycle is 1 millisecond. This cycle time can be defined via the Task Configuration of the
»PLC Designer«.
The DC cycle time on the tab of the EtherCAT master:
The task cycle time on the Configuration tab of the "MainTask":

Note!
• The DC cycle time to be set must match the set task cycle time.
• Select the cycle times according to the technical data from 1 ... 10 ms.
