 Operation in the Function Module Where an Event Occurred
The operation of the function module in which an event occurs depends on the level of the event.

tion Module
Note Major fault level errors occur only in the PLC Function Module. Operations described under the major fault
level column mean the operation in each function module when a major fault level error occurs in the PLC
Function Module.

User program execution ---
stops.
--- All axes stop. (The
stop method depends
on the error.)
--- EtherCAT communi-
cations stop. (The

1 Overview of Errors
Level of current event
Minor fault level
Operation continues.
• The affected
axes/axes group
stops. (The stop
method depends on
the settings.)
• The motion control
instruction is not exe-
cuted (for instructions
related to axis opera-
tion.)
I/O refreshing for Ether-
CAT communications
stops or continues
according to the fail-soft
operation settings in the
master. (If I/O refreshing
stops, the slaves oper-
ate according to the set-
tings in the slaves.)
Part of EtherNet/IP com-
munications stop.
(Online connections to
the Sysmac Studio and
communications con-
nections with an HMI is
possible if the online
connections or commu-
nications connection is
not the cause of the
error.)
Observation
• Axis operation
continues.
