8 Calculating Safety Reaction Times

For the EtherCAT communications timeout value, multiply the EtherCAT communications cycle

time by the "PDO communications timeout detection count" in the EtherCAT Unit setup and

use the resulting value.

Precautions for Correct Use

• To increase the communications timeout time, you much change both the safety task period

and the value of the FSoE watchdog timer.

Refer to 8-3-3 Settings for FSoE Watchdog Timers on page 8 - 10 for information on chang-

ing the FSoE watchdog timer.

• If the EtherCAT communications cycle is 250 us or lower, use the following minimum safety

task periods.

NX-SL££££ version 1.1 or later: 9 ms or higher

NX-SL££££ version 1.0 or later: 13 ms or higher

Additional Information

We recommend that you set the safety task period with plenty of leeway to allow for the possi-

bility of expanding the safety control system or safety programs in the future.
