*13. If you enable the cable redundancy in the network configuration, set a value other than No check .
*14. If the set value is Setting = Actual device , communications are not started with a slave, in a network,
that is replaced. If it is necessary to replace a slave while the set value is Setting = Actual device , you
must correct the network configuration information and transfer it to the EtherCAT master again. Set this
parameter to
Setting = Actual device only when strict management of the equipment configuration is
required.
*15. A CPU Unit with unit version 1.10 or later and Sysmac Studio version 1.12 or higher are required to use
this function. However, for project unit version 1.40 or later, this setting is not supported. Select Enable
slave monitoring option to use DC Synchronous Correction.
Precautions for Safe Use
• If the Fail-soft Operation Setting parameter is set to Stop , process data communications
will stop for all slaves when an EtherCAT communications error is detected in a slave.
The Servo Drive will operate according to the Servo Drive specifications.
Make sure that the Fail-soft Operation parameter setting results in safe operation when a de-
vice error occurs.
• If the Revision Check Method is set to No check , parameters are also transferred to slaves
with different EtherCAT revisions.
If an incompatible revision of a slave is connected, incorrect parameters may be set and op-
eration may not be correct.
If you set the
Revision Check Method to No check , make sure that only compatible slaves
are connected before transferring the parameters.
