minor fault status in which part of the slaves can
continue communications.

*1. If a minor fault occurs, slaves not separated from the EtherCAT master operate according to Fail-soft Opera-
tion Setting of the CPU Unit. Slaves separated from the EtherCAT master cannot continue communications.
Refer to the NJ/NX-series CPU Unit Built-in EtherCAT Port User’s Manual (Cat. No. W505) for details on
Fail-soft Operation Setting.

Minor fault All slaves can continue communications.
Removing a cable added from the network con-
figuration information and resetting the error
returns the communications status to the status
of No. 1.

Normal status The communications status changes to the ring
disconnection status in which all slaves can
continue communications. If a cable is discon-
nected or broken in this status, the status
changes to the minor fault status in which part
of the slaves can continue communications.
