Minimum PDO Communications Cycle Time
Do not set the communication cycle (PDO communication cycle time) for EtherCAT communication to a value
lower than the applicable minimum time given in the following table.
The minimum communication cycle (PDO communication cycle time) depends on the Data output byte size and
the use of the User area differs with the Number of controlled lines, as shown below. When multi-line random
trigger mode is used, the minimum communication cycle is the minimum value of the maximum byte size for each
line.
If the Communication cycle (PDO Communication cycle time) is set lower than the minimum value below, an
exception (AL status code: 0x0035) will occur and EtherCAT communications will be lost.
